Description

[0001] This application is a divisional application. The application number of the original application is 201810252314.9, and the original application date is March 26, 2018. The entire content of the original application is incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information processing method and device. Background Art

[0003] To cope with the explosive growth of mobile data traffic, the massive number of connected devices, and the emergence of various new services and application scenarios, the fifth-generation mobile communication (5G) system will emerge. Currently, the standards for the next-generation wireless communication technology (New Radio, NR) within the 5G system are under discussion to increase wireless network transmission rates and enhance user experience.

[0004] The 5G system will support a wide range of services, and various services have different requirements for latency. For idle user equipment (UE), different types of services will trigger a random access process. In the existing technology, services with different latency requirements may adopt different processing methods during random access, such as increasing the transmission power. However, in the existing technology, for services with different latency requirements, the random access process initiated by the UE is still based on competition. In the contention-based random access process, the UEs all randomly initiate random access. Then, it is possible that two UEs select the same resource, but the base station can only identify one UE at the same time. Because of the competition, the access delay of this access method may be greater.

[0005] How to further optimize the random access method to further reduce network access and data communication delays is still a problem to be solved urgently in this field. Summary of the Invention

[0006] Embodiments of the present application provide an information processing method and device for reducing network access and data communication delays.

[0007] To solve the above technical problems, the embodiments of the present application provide the following technical solutions:

[0008] In a first aspect, an embodiment of the present application provides an information processing method, comprising: a core network device determining service indication information of data to be processed, the service indication information being used to indicate that the data to be processed is delay-sensitive; and the core network device sending the service indication information. In an embodiment of the present application, the core network device can determine the service indication information corresponding to the data to be processed, the core network device can send the service indication information, and a terminal device can send and receive the data to be processed through the service indication information, so that the transmission mode or service requirements of the data to be processed are carried by the service indication information. The terminal device can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0009] In a possible design of the first aspect, the service indication information includes one or more of the following information: service type information, service priority information, service delay information, small packet transmission indication information, early data transmission (EDT) transmission indication information, dedicated resource allocation indication information, and service volume information. In an embodiment of the present application, the core network device determines the service information of the data to be processed. For example, the core network device can determine the service type, service priority, service delay, and service volume of the data to be processed. After the core network device determines at least one of the above service information, the core network device can generate service indication information. The service indication information can be used to indicate at least one of the following information: service type information, service priority information, service delay information, and service volume information. It is not limited to the above that the core network device can also determine whether to use small packet transmission, whether to use EDT transmission, and whether the network device needs to allocate dedicated resources to the terminal device based on the above service information. Therefore, the core network device can also indicate the following through service indication information: small packet transmission indication information, EDT transmission indication information, and dedicated resource allocation indication information.

[0010] In a possible design of the first aspect, when the service indication information includes the dedicated resource allocation indication information, the core network device determines the service indication information of the data to be processed, including: when the dedicated resource allocation indication information is to allocate dedicated resources, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or, when the dedicated resource allocation indication information is not to allocate dedicated resources, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. Among them, the core network device can also determine whether the data to be processed needs to be allocated dedicated resources, and through the mapping relationship between whether dedicated resources need to be allocated and whether it is delay-sensitive, it can instruct the network device whether the data to be processed is delay-sensitive through specific resource allocation. For example, when the data to be processed needs to be allocated dedicated resources, the core network device instructs the network device to determine that the data to be processed is delay-sensitive. When the data to be processed does not need to be allocated dedicated resources, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0011] In a possible design of the first aspect, when the service indication information includes the service volume size information, the core network device determines the service indication information of the data to be processed, including: when the service volume size corresponding to the service volume size information is less than or equal to a threshold, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or when the service volume size corresponding to the service volume size information is greater than the threshold, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. The service volume size information is used to indicate whether the corresponding service volume size is less than the threshold. The core network device may also determine whether the data to be processed is less than or equal to the threshold. By mapping whether the service volume size is less than or equal to the threshold and whether the data is delay-sensitive, the core network device may indicate to the network device whether the data to be processed is delay-sensitive based on the specific service volume size. For example, when the service volume of the data to be processed is less than or equal to the threshold, the core network device instructs the network device to determine that the data to be processed is delay-sensitive. When the service volume of the data to be processed is greater than the threshold, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0012] In a possible design of the first aspect, the method further includes: the core network device sends status indication information, and the status indication information is used to indicate the state that the terminal device enters after executing the random access process. The core network device can also generate status indication information, that is, the core network device indicates the state that the terminal enters after executing the random access process through the status indication information, so that the terminal device can determine the state that needs to be entered after the terminal device completes the random access process through the status indication information, wherein the terminal device can have multiple states, such as idle state, access state, inactive state (Inactive), etc. There are multiple ways for the core network device to send status indication information, for example, the core network device sends status indication information to the network device, and the network device then sends the status indication information to the terminal device.

[0013] In a possible design of the first aspect, the core network device sending the service indication information includes: when the core network device determines that the terminal device is in an idle state or an inactive state, the core network device sending the service indication information. Before sending the service indication information, the core network device needs to determine the terminal device's state. For example, when the terminal device is in an idle state, the core network device may send a paging message, with the paging message carrying the service indication information. For another example, when the terminal device is in an inactive state, the core network device may send a paging message, with the paging message carrying the service indication information. Because a base station does not know which base station an idle or inactive terminal device is located under, it cannot determine which base station's paging message will page the terminal device. Therefore, the core network device may set a range within which all base stations within the range will send paging messages for a particular terminal device. This range may be determined by a tracking area (TA) or a RAN area. The core network equipment can send paging messages when the terminal device is in an inactive state, thereby reducing the number of participating base stations. This is because reserving dedicated resources occupies air interface resources, and paging messages are a large-scale broadcast. If more base stations are involved, it may result in a large waste of resources.

[0014] In a possible design of the first aspect, when the service indication information includes the service type information, the core network device determines the service indication information of the data to be processed, including: when the service type information is a first service type, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or when the service type information is a second service type, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. The service type information may indicate the service type of the data to be processed. For example, service types are divided into at least two categories: a first service type and a second service type. Through a mapping relationship between different service types and whether they are delay-sensitive, the network device may be instructed by a specific service type whether the data to be processed is delay-sensitive. For example, the first service type may be AR data or VR data, and the second service type may be voice data. When the service type information of the data to be processed is AR data or VR data, the core network device instructs the network device to determine that the data to be processed is delay-sensitive. When the service type information of the data to be processed is voice data, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0015] In a possible design of the first aspect, when the service indication information includes the service priority information, the core network device determines the service indication information of the data to be processed, including: when the service priority information is high priority, the core network device instructs the network device to determine that the data to be processed is delay sensitive; or, when the service priority information is low priority, the core network device instructs the network device to determine that the data to be processed is delay insensitive. Wherein, the service priority information can represent the service priority of the data to be processed, for example, the service priority is divided into at least two categories: high priority and low priority. Through the mapping relationship between different service priorities and whether it is delay sensitive, the network device can be instructed by the specific service priority whether the data to be processed is delay sensitive. For example, when the service priority information of the data to be processed is high priority, the core network device instructs the network device to determine that the data to be processed is delay sensitive. When the service priority information of the data to be processed is low priority, the core network device instructs the network device to determine that the data to be processed is delay insensitive.

[0016] In a possible design of the first aspect, when the service indication information includes the service delay information, the core network device determines the service indication information of the data to be processed, including: when the service delay information is low delay, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or when the service delay information is high delay, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. The service delay information can represent the service delay of the data to be processed. For example, service delays are divided into at least two categories: low delay and high delay. Through the mapping relationship between different service delays and whether the data is delay-sensitive, the specific service delay can be used to indicate to the network device whether the data to be processed is delay-sensitive.

[0017] In a possible design of the first aspect, when the service indication information includes the small packet transmission indication information, the core network device determines the service indication information of the data to be processed, including: when the small packet transmission indication information is for using a small packet transmission mode, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or, when the small packet transmission indication information is for not using a small packet transmission mode, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. Among them, the core network device can also determine whether the data to be processed needs to be transmitted using small packets, and through the mapping relationship between whether small packet transmission needs to be used and whether it is delay-sensitive, it can indicate to the network device whether the data to be processed is delay-sensitive through specific transmission.

[0018] In a possible design of the first aspect, when the service indication information includes the EDT transmission indication information, the core network device determines the service indication information of the data to be processed, including: when the EDT transmission indication information is for using the EDT transmission mode, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or, when the EDT transmission indication information is for not using the EDT transmission mode, the core network device instructs the network device to determine that the data to be processed is delay-insensitive. The core network device can also determine whether the data to be processed needs to be transmitted using EDT, and through the mapping relationship between whether EDT transmission needs to be used and whether it is delay-sensitive, it can indicate to the network device whether the data to be processed is delay-sensitive through specific transmission.

[0019] In a possible design of the first aspect, the core network device sending the status indication information includes: the core network device sending the status indication information to the terminal device through non-access layer NAS signaling. That is, the core network device can directly send the service indication information to the terminal device.

[0020] In a possible design of the first aspect, the core network device sending the service indication information includes: the core network device sending a paging message carrying the service indication information. The core network device may send a paging message that carries the service indication information, for example, by using a reserved field in the paging message to carry the service indication information, or by extending a new field in an existing paging message to carry the service indication information.

[0021] In a possible design of the first aspect, the core network device sending the status indication information includes: the core network device sending the status indication information to the terminal device via non-access stratum (NAS) signaling. Optionally, the core network device may also send the status indication information to the network device via a paging message, and the network device then sends the status indication information to the terminal device. For example, a communication connection is established between the core network device and the network device, and the core network device sends a paging message carrying the status indication information to the network device.

[0022] In a possible design of the first aspect, the dedicated resources include: dedicated random access resources, and / or dedicated cell radio network temporary identifiers (CRNTIs). For example, the dedicated random access resources may include: dedicated preambles and / or dedicated time-frequency resources. The allocation method of the dedicated random access resources may be the same as the random access resources allocated by the network device for the EDT transmission mode. When the dedicated resource is a dedicated CRNTI, the network device may directly send downlink data to the terminal device via the allocated dedicated CRNTI.

[0023] In a second aspect, an embodiment of the present application further provides an information processing method, comprising: a network device determining service indication information of data to be processed, the service indication information being used to indicate that the data to be processed is delay-sensitive; and the network device sending the service indication information. In an embodiment of the present application, the network device can determine the service indication information corresponding to the data to be processed, the network device can send the service indication information, and the terminal device can send and receive the data to be processed through the service indication information, so that the transmission method or service requirement of the data to be processed is carried by the service indication information. The terminal device can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0024] In a possible design of the second aspect, the service indication information includes one or more of the following information: service type information, service priority information, service delay information, packet transmission indication information, early data transmission EDT transmission indication information, dedicated resource allocation indication information, and service volume information.

[0025] In a possible design of the second aspect, the method further includes: the network device allocating dedicated resources to the terminal device; and the network device determining resource configuration information indicating the dedicated resources. When the core network device instructs the network device to allocate dedicated resources, the network device may allocate dedicated resources to the terminal device according to the instruction of the core network device. Alternatively, the network device may determine whether to allocate dedicated resources to the terminal device based on its own circumstances. When the network device allocates dedicated resources to the terminal device, the terminal device may use the dedicated resources to send and receive data to be processed.

[0026] In a possible design of the second aspect, after the network device sends the service indication information, the method further includes: the network device sending the data to be processed to the terminal device via a dedicated CRNTI. For example, the data to be processed is downlink data, and the network device may send the downlink data to the terminal device via a dedicated CRNTI. The terminal device determines the dedicated CRNTI allocated by the network device based on the service indication message, and the terminal device uses the dedicated CRNTI to monitor the control channel. The terminal device then receives the downlink data via a data channel scheduled by the control channel, thereby enabling early transmission of the downlink data from the network device to the terminal device.

[0027] In a possible design of the second aspect, the network device sending the service indication information includes: the network device sending the service indication information carrying the resource configuration information.

[0028] In a possible design of the second aspect, the dedicated resources include: dedicated random access resources, and / or dedicated cell radio network temporary identifiers (CRNTIs). For example, the dedicated random access resources may include: dedicated preambles and / or dedicated time-frequency resources. The allocation method of the dedicated random access resources may be the same as the random access resources allocated by the network device for the EDT transmission mode. When the dedicated resource is a dedicated CRNTI, the network device may directly send downlink data to the terminal device through the allocated dedicated CRNTI.

[0029] In a possible design of the second aspect, after the network device sends the service indication information, the method includes: the network device sends the data to be processed to the terminal device through a random access response RAR message or a radio resource control RRC command. The RRC command that the network device can use can specifically be an RRC establishment or reconstruction command, such as Msg4 or other RRC signaling. If the network device detects a random access process initiated by the terminal device through dedicated resources, it can send downlink data to the terminal device in a RAR message or Msg4, thereby realizing early transmission of downlink data from the network device to the terminal device.

[0030] In a third aspect, embodiments of the present application provide an information processing method, comprising: a terminal device receiving service indication information of data to be processed, the service indication information being used to indicate that the data to be processed is latency-sensitive; and the terminal device sending and receiving the data to be processed based on the service indication information. The terminal device can send and receive the data to be processed using the service indication information, thereby enabling the transmission method or service requirements of the data to be processed to be carried by the service indication information. The terminal device can quickly begin processing the data to be processed using the service indication information, thereby reducing network access and data communication delays.

[0031] In a possible design of the third aspect, the service indication information includes one or more of the following information: service type information, service priority information, service delay information, packet transmission indication information, early data transmission EDT transmission indication information, dedicated resource allocation indication information, and service volume information.

[0032] In a possible design of the third aspect, the terminal device sends and receives the data to be processed according to the service indication information, including: the terminal device determines that the data to be processed is delay-sensitive according to the service type information being the first service type; or, the terminal device determines that the data to be processed is delay-sensitive according to the service priority information being high priority; or, the terminal device determines that the data to be processed is delay-sensitive according to the service delay information being low delay; or, the terminal device determines that the data to be processed is delay-sensitive according to the small packet transmission indication information using the small packet transmission mode; or, the terminal device determines that the data to be processed is delay-sensitive according to the EDT transmission indication information using the EDT transmission mode; or, the terminal device determines that the data to be processed is delay-sensitive according to the dedicated resource allocation indication information allocating dedicated resources; or, the terminal device determines that the data to be processed is delay-sensitive according to the business volume size information being less than or equal to a threshold value; when the data to be processed is delay-sensitive, the terminal device uses the small packet transmission mode or the EDT transmission mode to send and receive the data to be processed.

[0033] In a possible design of the third aspect, the terminal device sends and receives the data to be processed based on the service indication information, including: the terminal device obtaining resource configuration information indicating dedicated resources; the terminal device determining dedicated random access resources based on the resource configuration information; the terminal device using the dedicated random access resources to send a random access request to the network device, and sending and receiving the data to be processed via a random access response (RAR) message or a radio resource control (RRC) command. The network device may allocate dedicated resources to the terminal device and may also send resource configuration information to the terminal device. After receiving the resource configuration information, the terminal device parses the resource configuration information to determine the dedicated random access resource, and the terminal device uses the dedicated random access resource to send a random access request to the network device. The RRC command that the network device may use may specifically be an RRC establishment or re-establishment command, such as "Msg4" or other RRC signaling. Upon detecting that the terminal device has initiated a random access process using dedicated resources, the network device may send downlink data to the terminal device in a RAR message or Msg4, thereby enabling early transmission of downlink data from the network device to the terminal device.

[0034] In a possible design of the third aspect, the terminal device sends and receives the data to be processed according to the service indication information, including: the terminal device obtains resource configuration information indicating dedicated resources; the terminal device determines a dedicated cell radio network temporary identification code CRNTI according to the resource configuration information; the terminal device uses the dedicated CRNTI to monitor a control channel; and the terminal device receives the data to be processed through a data channel scheduled by the control channel. For example, if the data to be processed is downlink data, the network device can send the downlink data to the terminal device through a dedicated CRNTI, the terminal device determines the dedicated CRNTI allocated by the network device according to the service indication message, the terminal device uses the dedicated CRNTI to monitor the control channel, and then the terminal device receives the downlink data through the data channel scheduled by the control channel, thereby achieving early transmission of downlink data from the network device to the terminal device.

[0035] In a possible design of the third aspect, when the data to be processed is low-latency data, or high-priority data, or data transmitted in small packets, or data transmitted in EDT, the terminal device is configured to use a backoff strategy and / or a power ramping strategy to reduce the access delay of the terminal device during random access.

[0036] In a possible design of the third aspect, the method further includes: the terminal device receives status indication information via non-access stratum NAS signaling sent by the core network device; or the terminal device receives the status indication information via a paging message sent by the network device; and the terminal device enters the state indicated by the status indication information after executing the random access process. Taking the case where the data to be processed is downlink data as an example, the core network device may also generate status indication information, that is, the core network device indicates the state that the terminal enters after executing the random access process through the status indication information, so that the terminal device may determine the state that it needs to enter after completing the random access process through the status indication information, wherein the terminal device may have multiple states, such as an idle state, an access state, an inactive state, etc. The core network device may send status indication information in multiple ways, such as the core network device sending status indication information to the network device, and the network device then sending the status indication information to the terminal device. The terminal device may receive status indication information from the core network device or the network device.

[0037] In a possible design of the third aspect, the method further includes: the terminal device determining a state to enter after completing the random access procedure based on the traffic volume information. The core network device may determine the traffic volume of the current communication so that the terminal device can determine whether to enter a connected state or remain in an idle state after completing the random access procedure using the EDT method. For example, a traffic volume threshold may be set; when the threshold is exceeded, the terminal device enters a connected state; otherwise, the terminal device remains in an idle state.

[0038] In a possible design of the third aspect, the method further includes: the terminal device sending status indication information to the network device, the status indication information being used to indicate a state entered by the terminal device after sending the data to be processed. For a calling service, the data to be processed is uplink data, the terminal device may further send the uplink data to the network device, and the terminal device may further generate the status indication information, so that the network device can determine the state entered by the terminal device after sending the uplink data based on the status indication information.

Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0085] Figure 1 A schematic diagram of the structure of a possible radio access network (RAN) according to an embodiment of the present application is shown. The RAN may be a base station access system of a 2G network (i.e., the RAN includes a base station and a base station controller), a base station access system of a 3G network (i.e., the RAN includes a base station and an RNC), a base station access system of a 4G network (i.e., the RAN includes an eNB and an RNC), or a base station access system of a 5G network.

[0086] The RAN includes one or more network devices 20. The radio access network can be connected to a core network (CN) device 30. The CN can be the MME and / or S-GW of a 4G network, or the SGSN or GGSN of a 3G network, or the access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) of the next generation core network (NG-Core) of a 5G network. The network device 20 can be any device with wireless transceiver functions, or a chip set in a device with specific wireless transceiver functions. The network device 20 includes but is not limited to: base stations (such as base stations BS, base stations NodeB, evolved base stations eNodeB or eNB, base stations gNodeB or gNB in fifth-generation 5G communication systems, base stations in future communication systems, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes), etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, etc. Multiple base stations can support networks of one or more technologies mentioned above, or future evolved networks. The core network can support networks of one or more technologies mentioned above, or future evolved networks. The base station can include one or more co-sited or non-co-sited transmission receiving points (TRP). The network device 20 can also be a wireless controller, a centralized unit (CU) or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The network device can also be a server, a wearable device, or a vehicle-mounted device. The following is an example of network device 20 being a base station. The multiple network devices 20 can be base stations of the same type or different types. The base station can communicate with the terminal device 10, or it can communicate with the terminal device 10 through a relay station. The terminal 10 can support communication with multiple base stations of different technologies. For example, the terminal device can support communication with a base station supporting an LTE network, or it can support communication with a base station supporting a 5G network, or it can support dual connection with a base station of an LTE network and a base station of a 5G network. For example, the terminal is connected to a radio access network (RAN) node of a wireless network.Currently, some examples of RAN nodes include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP). In a network architecture, network equipment may include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including CU nodes and DU nodes.

[0087] The terminal device 10, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), or terminal, is a device that provides voice and / or data connectivity to a user, or a chip within the device, such as a handheld device or vehicle-mounted device with wireless connection capabilities. Currently, some examples of terminal devices include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes.

[0088] The core network device 30 may be a Mobility Management Entity (MME) in a 4G network or an Access Management Function (AMF) in a 5G network. The core network device 30 may be a physical entity, a functional entity, or a chip disposed within a physical entity.

[0089] First, the paging process in the embodiment of the present application is schematically explained: when the core network device (such as MME) pages a terminal device, it sends a paging message to the base station, and the base station pages the terminal device. After the core network device initiates the paging, it starts a timer. If the timer times out and no paging response is received from the terminal device, the paging is resent and the timer is restarted. If a paging response is received, the timer is stopped. Base station (such as eNB): After receiving the paging message from the core network device, it will page the terminal device according to the paging message sent by the core network device. The terminal device (such as UE) wakes up once every period to listen for paging according to the configuration of the core network device.

[0090] See also Figure 2 As shown, it is a schematic diagram of an interaction process between a network device, a terminal device, and a core network device provided in an embodiment of the present application. The information processing method provided in an embodiment of the present application mainly includes the following processes:

[0091] S01. The core network device determines service indication information of data to be processed.

[0092] In an embodiment of the present application, the core network device may specifically be an MME or an AMF. The core network device first determines the data to be processed, which may specifically be downlink data to be sent to the terminal device. The core network device determines the service information of the data to be processed. For example, the core network device may determine the service type, service priority, service delay, and service volume of the data to be processed. Among them, the service type of the data to be processed is voice data, video data, augmented reality (AR) data, or virtual reality (VR) data. The service priority of the data to be processed refers to different priorities such as high priority, medium priority, or low priority. The service delay of the data to be processed refers to low delay, medium delay, or high delay. The service volume of the data to be processed refers to the amount of data occupied by the data to be processed or the transmission volume.

[0093] After the core network device determines at least one of the above service information, the core network device can generate service indication information, and the core network device can indicate that the data to be processed is delay sensitive through the service indication information. Whether the data to be processed is delay sensitive can be determined by the service attributes of the data to be processed. Among them, delay sensitivity means that the data to be processed requires low delay or very short delay, that is, the data to be processed cannot tolerate excessive delay. The core network device can first determine that the data to be processed is delay sensitive before processing the data, and indicate that the data to be processed is delay sensitive through service indication information, so that the network device and the terminal device can determine that the data to be processed is delay sensitive according to the service indication information before sending and receiving data, and then can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0094] In some embodiments of the present application, the service indication information may be used to indicate at least one of the following information: service type information, service priority information, service latency information, and service volume information. It is not limited to the following: the core network device may also determine, based on the above service information, whether to use small packet transmission, whether to use Early Data Transmission (EDT), and whether the network device needs to allocate dedicated resources for the terminal device. Therefore, the core network device may also indicate, through the service indication information: small packet transmission indication information, EDT transmission indication information, and dedicated resource allocation indication information. Small packet transmission refers to the transmission of data packets with very small service volumes. Traditionally, data communication can only be carried out after the UE and the network access the network through a random access process and establish a bearer with the network. Small packet transmission refers to data transmission during the random access process. For small packet transmission, the UE may send a small data packet. Using small packet transmission, data can be transmitted directly during the random access process, eliminating the need for a subsequent bearer establishment process. EDT transmission also refers to data transmission during the random access process, eliminating the need for a bearer establishment process. Dedicated resource allocation indication information may be used to indicate whether the network device needs to allocate dedicated resources for the terminal device. Upon receiving the dedicated resource allocation indication information, the network device may determine whether to allocate dedicated resources to the terminal device based on its actual circumstances, such as resource availability. In other words, the dedicated resource allocation indication information sent by the core network device may only be a suggestion to the network device, and the network device may still decide whether to allocate dedicated resources based on its actual circumstances. Upon receiving the dedicated resource allocation indication information, the terminal device may determine whether the network device has allocated dedicated resources to it.

[0095] S02. The core network device sends service indication information to the network device.

[0096] For example, a core network device establishes a communication connection with a network device, and the core network device sends service indication information to the network device. Alternatively, the core network device can communicate directly with a terminal device through transparent transmission, sending service indication information directly to the terminal device. The terminal device can then use this service indication information to determine whether the data being processed is latency-sensitive.

[0097] S03. The network device receives service indication information of the data to be processed.

[0098] Among them, the network device may refer to a base station, for example, the base station receives service indication information from the core network device. The network device receives the service indication information, and through the service indication information, the service indication of the core network device for the data to be processed can be determined. For example, the network device can determine the following based on the service indication information: service type information, service priority information, service delay information, packet transmission indication information, EDT transmission indication information, dedicated resource allocation indication information, and service volume information. For example, the network device can obtain the service type information of the data to be processed, thereby determining the service type of the data to be processed, or obtain the service priority information, service delay information, and service volume information of the data to be processed. Alternatively, the core network device can also determine whether to use packet transmission, whether to use EDT transmission, and whether the network device needs to allocate dedicated resources to the terminal device based on the service indication information. When the core network device instructs the network device to allocate dedicated resources, the network device can allocate dedicated resources to the terminal device based on the instruction of the core network device.

[0099] S04. The network device sends service indication information to the terminal device.

[0100] In an embodiment of the present application, after the network device receives the service indication information, the network device sends the service indication information to the terminal device.

[0101] It should be noted that in an embodiment of the present application, if the network device obtains service indication information from the core network device, then when the network device sends the service indication information to the terminal device, the network device does not necessarily have to send the received service indication information to the terminal device in its entirety, or at least not send all the contents of the service indication information to the terminal device. The network device only processes the service indication information and then sends it to the terminal device. As long as the terminal device determines that the data to be processed is delay-sensitive after receiving the indication information from the network device, it is sufficient.

[0102] Optionally, after the network device receives the service indication information from the core network device, the network device sends the indication information in the service indication information to the terminal device. For example, the service indication information includes both small packet transmission indication information and EDT transmission indication information. The network device only sends the EDT transmission indication information to the terminal device, and no longer sends the small packet transmission indication information at the same time. Alternatively, some service indication information is only used to instruct the network device to perform related operations without being sent to the terminal device. For example, the service indication information includes dedicated resource allocation indication information. The network device can allocate dedicated resources to the terminal according to the dedicated resource allocation indication information, and send the configuration information of the allocated dedicated resources to the terminal device, instead of sending the dedicated resource allocation indication information to the terminal device.

[0103] S05. The terminal device receives service indication information of the data to be processed.

[0104] In an embodiment of the present application, a terminal device may receive service indication information from a network device, or a core network device may communicate directly with the terminal device via transparent transmission, with the core network device directly sending the service indication information to the terminal device. The terminal device may then determine, based on the service indication information, that the data to be processed is latency-sensitive. The terminal device may determine, based on the service indication information, one or more of the following information: service type information, service priority information, service latency information, packet transmission indication information, EDT transmission indication information, dedicated resource allocation indication information, and service volume information.

[0105] S06. The terminal device sends and receives data to be processed according to the service instruction information.

[0106] In an embodiment of the present application, a terminal device may receive service indication information, and the terminal device may determine the method to be used to send and receive data to be processed through the service indication information. For example, the data to be processed may be downlink data, and the terminal device may determine the service type information of the downlink data through the service indication information, thereby determining the service type of the downlink data, or obtaining the service priority information, service delay information, and service volume information of the downlink data. Alternatively, the terminal device may also determine whether to use packet transmission or EDT transmission based on the service indication information, or the terminal device may also obtain whether the network device has allocated dedicated resources for the terminal device and the dedicated resources allocated to the terminal device based on the service indication information.

[0107] In an embodiment of the present application, a core network device may determine service indication information corresponding to the data to be processed, and the core network device may send the service indication information. A terminal device may obtain the service indication information and send and receive the data to be processed according to the service indication information, thereby enabling the transmission mode or service requirements of the data to be processed to be carried by the service indication information. The terminal device may quickly start processing the data to be processed based on the service indication information, thereby reducing network access and data communication delays.

[0108] Next, the information processing method provided by the embodiment of the present application is described from the perspectives of network equipment, core network equipment and terminal equipment. First, please refer to Figure 3 As shown, the embodiment of the present application provides an information processing method, including:

[0109] 301. A core network device determines service indication information of data to be processed, where the service indication information is used to indicate that the data to be processed is delay sensitive.

[0110] The core network device can generate service indication information, and the core network device can indicate that the data to be processed is delay-sensitive through the service indication information. Whether the data to be processed is delay-sensitive can be determined by the service attributes of the data to be processed. Among them, delay sensitivity means that the data to be processed requires low delay or very short delay, that is, the data to be processed cannot tolerate excessive delay. Before processing the data, the core network device can first determine that the data to be processed is delay-sensitive, and indicate that the data to be processed is delay-sensitive through service indication information, so that the network device and the terminal device can determine that the data to be processed is delay-sensitive according to the service indication information before sending and receiving data, and then can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0111] In an embodiment of the present application, the core network device may specifically be an MME or an AMF. The core network device first determines the data to be processed, which may specifically be downlink data to be sent to the terminal device. The core network device determines the service information of the data to be processed. For example, the core network device may determine the service type, service priority, service delay, and service volume of the data to be processed. After the core network device determines at least one of the above service information, the core network device may generate service indication information, which may be used to indicate at least one of the following information: service type information, service priority information, service delay information, and service volume information. It is not limited that the core network device may also determine whether to use packet transmission, whether to use EDT transmission, and whether the network device is required to allocate dedicated resources for the terminal device based on the above service information. Therefore, the core network device may also indicate through service indication information: packet transmission indication information, EDT transmission indication information, and dedicated resource allocation indication information.

[0112] In some embodiments of the present application, the aforementioned dedicated resources include: dedicated random access resources, and / or dedicated cell radio network temporary identification codes (Cell Radio Network Temporary Identify, CRNTI). For example, the dedicated random access resources may include: dedicated preamble sequences (preamble) and / or dedicated time-frequency resources. The allocation method of the dedicated random access resources can be the same as the random access resources allocated by the network device for the EDT transmission mode. When the dedicated resource is a dedicated CRNTI, the network device can directly send downlink data to the terminal device through the allocated dedicated CRNTI.

[0113] In some embodiments of the present application, when the service indication information includes service type information, the core network device determines the service indication information of the data to be processed in step 301, including:

[0114] When the service type information is the first service type, the core network device instructs the network device to determine whether the data to be processed is delay sensitive; or,

[0115] When the service type information is the second service type, the core network device instructs the network device to determine whether the data to be processed is delay-insensitive.

[0116] Among them, the service type information can indicate the service type of the data to be processed. For example, the service type is divided into at least two categories: a first service type and a second service type. Through the mapping relationship between different service types and whether they are delay sensitive, the network device can be instructed by the specific service type whether the data to be processed is delay sensitive. For example, the first service type may be AR data or VR data, and the second service type is voice data. When the service type information of the data to be processed is AR data or VR data, the core network device instructs the network device to determine that the data to be processed is delay sensitive. When the service type information of the data to be processed is voice data, the core network device instructs the network device to determine that the data to be processed is delay insensitive.

[0117] In some embodiments of the present application, when the service indication information includes service priority information, the core network device determines the service indication information of the data to be processed in step 301, including:

[0118] When the service priority information is high priority, the core network device instructs the network device to determine that the data to be processed is delay sensitive; or,

[0119] When the service priority information is low priority, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0120] Among them, the service priority information can represent the service priority of the data to be processed. For example, the service priority is divided into at least two categories: high priority and low priority. Through the mapping relationship between different service priorities and whether the data is delay sensitive, the network device can be instructed by the specific service priority whether the data to be processed is delay sensitive. For example, when the service priority information of the data to be processed is high priority, the core network device instructs the network device to determine that the data to be processed is delay sensitive. When the service priority information of the data to be processed is low priority, the core network device instructs the network device to determine that the data to be processed is delay insensitive. It is not limited that the service priority can be divided into more levels, which will not be repeated here.

[0121] In some embodiments of the present application, when the service indication information includes service delay information, step 301, in which the core network device determines the service indication information of the data to be processed, includes:

[0122] When the service delay information indicates low delay, the core network device instructs the network device to determine that the data to be processed is delay-sensitive; or

[0123] When the service delay information indicates high delay, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0124] Among them, the service delay information can represent the service delay of the data to be processed. For example, the service delay is divided into at least two categories: low delay and high delay. Through the mapping relationship between different service delays and whether the data is delay sensitive, the specific service delay can be used to indicate whether the data to be processed by the network device is delay sensitive. For example, when the service delay information of the data to be processed is low delay, the core network device instructs the network device to determine that the data to be processed is delay sensitive. When the service delay information of the data to be processed is high delay, the core network device instructs the network device to determine that the data to be processed is delay insensitive. It is not limited that the service delay can be divided into more levels, which will not be repeated here.

[0125] In some embodiments of the present application, when the service indication information includes packet transmission indication information, the core network device determines the service indication information of the data to be processed in step 301, including:

[0126] When the small packet transmission instruction information indicates that the small packet transmission mode is used, the core network device instructs the network device to determine whether the data to be processed is delay sensitive; or

[0127] When the small packet transmission indication information indicates not to use the small packet transmission mode, the core network device instructs the network device to determine whether the data to be processed is delay-insensitive.

[0128] The core network device can also determine whether the data to be processed requires transmission using small packets. By mapping the need for small packet transmission to latency sensitivity, the core network device can instruct the network device whether the data to be processed is latency sensitive through specific transmission. For example, if the data to be processed requires transmission using small packets, the core network device instructs the network device to determine that the data to be processed is latency sensitive. If the data to be processed does not require transmission using small packets, the core network device instructs the network device to determine that the data to be processed is latency insensitive.

[0129] In some embodiments of the present application, when the service indication information includes EDT transmission indication information, the core network device determines the service indication information of the data to be processed in step 301, including:

[0130] When the EDT transmission instruction information indicates that the EDT transmission mode is used, the core network device instructs the network device to determine whether the data to be processed is delay sensitive; or

[0131] When the EDT transmission instruction information indicates not to use the EDT transmission mode, the core network device instructs the network device to determine whether the data to be processed is delay-insensitive.

[0132] The core network device can also determine whether the data to be processed requires EDT transmission. By mapping the need for EDT transmission to latency sensitivity, the core network device can instruct the network device whether the data to be processed is latency sensitive through specific transmission. For example, if the data to be processed requires EDT transmission, the core network device instructs the network device to determine whether the data to be processed is latency sensitive. If the data to be processed does not require EDT transmission, the core network device instructs the network device to determine whether the data to be processed is latency insensitive.

[0133] In some embodiments of the present application, when the service indication information includes dedicated resource allocation indication information, the core network device determines the service indication information of the data to be processed in step 301, including:

[0134] When the dedicated resource allocation indication information indicates allocating dedicated resources, the core network device instructs the network device to determine whether the data to be processed is delay sensitive; or

[0135] When the dedicated resource allocation indication information indicates that dedicated resources are not allocated, the core network device instructs the network device to determine whether the data to be processed is delay-insensitive.

[0136] The core network device can also determine whether the data being processed requires allocation of dedicated resources. By mapping the need for dedicated resource allocation to latency sensitivity, the core network device can indicate to the network device whether the data being processed is latency sensitive through specific resource allocation. For example, if the data being processed requires allocation of dedicated resources, the core network device instructs the network device to determine that the data being processed is latency sensitive. If the data being processed does not require allocation of dedicated resources, the core network device instructs the network device to determine that the data being processed is latency insensitive.

[0137] In some embodiments of the present application, when the service indication information includes service volume information, step 301 of the core network device determining the service indication information of the data to be processed includes:

[0138] When the traffic volume size corresponding to the traffic volume size information is less than or equal to the threshold, the core network device instructs the network device to determine that the data to be processed is delay sensitive; or,

[0139] When the traffic volume size corresponding to the traffic volume size information is greater than a threshold, the core network device instructs the network device to determine whether the data to be processed is delay-insensitive.

[0140] The core network device can also determine whether the data to be processed is less than or equal to a threshold. By mapping whether the data is less than or equal to the threshold and whether it is delay-sensitive, the core network device can indicate to the network device whether the data to be processed is delay-sensitive based on the specific traffic volume. For example, when the traffic volume of the data to be processed is less than or equal to the threshold, the core network device instructs the network device to determine that the data to be processed is delay-sensitive. When the traffic volume of the data to be processed is greater than the threshold, the core network device instructs the network device to determine that the data to be processed is delay-insensitive.

[0141] 302. The core network device sends service indication information.

[0142] A communication connection is established between the core network device and the network device, and the core network device sends service indication information to the network device.

[0143] In some embodiments of the present application, step 302 of the core network device sending service indication information includes:

[0144] The core network device sends a paging message carrying service indication information.

[0145] Among them, the core network device can send a paging message, which carries service indication information in the paging message, for example, using a reserved field in the paging message to carry the service indication information, or extending a new field in the original paging message to carry the service indication information.

[0146] Optionally, the core network device may also send the service indication information to the terminal device via Non-Access Stratum (NAS) signaling, that is, the core network device may directly send the service indication information to the terminal device.

[0147] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0148] The core network device sends status indication information, which is used to indicate the state entered by the terminal device after performing the random access process.

[0149] The core network device may also generate status indication information, that is, the core network device indicates the state that the terminal enters after performing the random access process through the status indication information, so that the terminal device can determine the state to be entered after the terminal device completes the random access process through the status indication information, wherein the terminal device can have multiple states, such as idle state, access state, inactive state, etc. The core network device can send status indication information in multiple ways, such as the core network device sends status indication information to the network device, and the network device then sends the status indication information to the terminal device.

[0150] An example is given below. The core network device generates status indication information based on the need to use small packet transmission mode for downlink data. When the downlink data needs to be transmitted using the small packet transmission mode, the status indication information is used to instruct the terminal device to remain in an idle state after receiving the downlink data. When the downlink data is not transmitted using the small packet transmission mode, the status indication information is used to instruct the terminal device to enter a connected state after receiving the downlink data.

[0151] Optionally, the core network device may also only send the status indication information. That is, the core network device may only send the service indication information, or may only send the status indication information, or may send both the service indication information and the status indication information, which is not limited in this embodiment.

[0152] Furthermore, in some embodiments of the present application, the core network device sending the status indication information includes:

[0153] The core network device sends status indication information to the terminal device through Non Access Stratum (NAS) signaling.

[0154] Optionally, the core network device may also send the status indication information to the network device via a paging message, and the network device may then send the status indication information to the terminal device. For example, a communication connection may be established between the core network device and the network device, and the core network device may send a paging message carrying the status indication information to the network device.

[0155] Among them, the core network device can send a paging message, carrying the status indication information in the paging message, for example, using a reserved field in the paging message to carry the status indication information, or extending a new field in the original paging message to carry the status indication information.

[0156] After receiving the above-mentioned paging message sent by the core network device, the network device sends a paging message carrying the status indication information to the terminal device.

[0157] The status indication information sent by the terminal device through the core network device can determine the state that the terminal device needs to enter after completing the random access process, solving the problem that the terminal device cannot determine which state it should enter after performing the random access process.

[0158] In some embodiments of the present application, step 302 of the core network device sending service indication information includes:

[0159] When the core network device determines that the status of the terminal device is idle or inactive, the core network device sends service indication information.

[0160] Before sending service indication information, the core network device needs to determine the terminal device's status. For example, when the terminal device is in the idle state, the core network device can send a paging message that carries the service indication information. Alternatively, when the terminal device is in the inactive state, the core network device can send a paging message that carries the service indication information. For paging, a base station does not know which base station an idle or inactive terminal device is located under, meaning it cannot determine which base station should send the paging message to reach the terminal device. Therefore, the core network device can set a range within which all base stations within the range will send paging messages for a particular terminal device. This range can be determined by a tracking area (TA) or RAN area. The core network device can send paging messages when the terminal device is in the inactive state, thereby reducing the number of participating base stations. Reserving dedicated resources consumes air interface resources, and paging messages are broadcast over a large area. If many base stations are involved, this can result in significant resource waste.

[0161] Through the examples of the method executed by the core network device in the above-mentioned embodiment, it can be seen that the core network device can determine the service indication information corresponding to the data to be processed, the core network device can send the service indication information, and the terminal device can send and receive the data to be processed through the service indication information, so that the transmission method or service requirements of the data to be processed are carried by the service indication information. The terminal device can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0162] The above embodiment describes the information processing method provided by the embodiment of the present application from the perspective of the core network device. Next, the information processing method provided by the embodiment of the present application is described from the perspective of the network device. Figure 4 As shown, the embodiment of the present application provides an information processing method, including:

[0163] 401. A network device determines service indication information of data to be processed, where the service indication information is used to indicate that the data to be processed is delay sensitive.

[0164] In some embodiments of the present application, step 401, in which the network device determines the service indication information of the data to be processed, includes: the network device receives the service indication information sent by the core network device. The network device may refer to a base station, for example, the base station receives the service indication information from the core network device. The network device receives the service indication information, and through the service indication information, the network device can determine the service indication of the core network device for the data to be processed. For example, the network device can determine the following based on the service indication information: service type information, service priority information, service delay information, packet transmission indication information, EDT transmission indication information, dedicated resource allocation indication information, and service volume information. For example, the network device can obtain the service type information of the data to be processed, thereby determining the service type of the data to be processed, or obtain the service priority information, service delay information, and service volume information of the data to be processed. Alternatively, the core network device can also determine whether to use packet transmission, whether to use EDT transmission, and whether the network device needs to allocate dedicated resources to the terminal device based on the service indication information.

[0165] Optionally, the network device may independently determine all or part of the service indication information without receiving the service indication information from the core network device. For example, the network device may determine whether to allocate dedicated resources based on its own resource conditions and determine the dedicated resource allocation indication information.

[0166] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0167] Network equipment allocates dedicated resources to terminal devices;

[0168] The network device determines resource configuration information indicative of dedicated resources.

[0169] When the core network device instructs the network device to allocate dedicated resources, the network device may allocate dedicated resources to the terminal device according to the instruction of the core network device. Alternatively, the network device may determine whether to allocate dedicated resources to the terminal device based on its own circumstances. When the network device allocates dedicated resources to the terminal device, the terminal device may use the dedicated resources to send and receive data to be processed.

[0170] Optionally, the dedicated resource allocation indication information can be sent explicitly, for example, using a dedicated field to carry the dedicated resource allocation indication information; it can also be sent implicitly, for example, when the network device allocates dedicated resources to the terminal device, the dedicated resource allocation indication information can be implicitly indicated.

[0171] In some embodiments of the present application, the aforementioned dedicated resources include dedicated random access resources and / or dedicated CRNTIs. For example, the dedicated random access resources may include dedicated preamble sequences and / or dedicated time-frequency resources. The dedicated random access resources may be allocated in the same manner as the random access resources allocated by the network device for the EDT transmission mode. When the dedicated resource is a dedicated CRNTI, the network device may directly send downlink data to the terminal device using the allocated dedicated CRNTI.

[0172] 402. The network device sends service indication information.

[0173] In an embodiment of the present application, after the network device obtains the service indication information, the network device sends the service indication information to the terminal device.

[0174] In the aforementioned embodiment, if the network device also generates resource configuration information indicating dedicated resources, step 402 of the network device sending service indication information includes: the network device sending service indication information carrying resource configuration information. That is, the service indication information sent by the network device also carries resource configuration information indicating dedicated resources. Thus, after receiving the service indication information, the network device can obtain the resource configuration information based on the service indication information, and the terminal device can use the dedicated resources to send and receive data to be processed.

[0175] In some embodiments of the present application, after the network device sends the service indication information in step 402, the information processing method provided in the embodiment of the present application may further perform the following steps:

[0176] The network device sends the data to be processed to the terminal device through a Random Access Response (RAR) message or a Radio Resource Control (RRC) command.

[0177] The RRC command that the network device can use can specifically be an RRC establishment or re-establishment command, such as Msg4 or other RRC signaling. When the network device detects a random access process initiated by the terminal device through dedicated resources, it can send downlink data to the terminal device in a RAR message or Msg4, thereby achieving early transmission of downlink data from the network device to the terminal device.

[0178] In some embodiments of the present application, after the network device sends the service indication information in step 402, the information processing method provided in the embodiment of the present application may further perform the following steps:

[0179] The network device sends the data to be processed to the terminal device through a dedicated CRNTI.

[0180] For example, the data to be processed is downlink data. The network device can send downlink data to the terminal device through a dedicated CRNTI. The terminal device determines the dedicated CRNTI allocated by the network device based on the service indication message. The terminal device uses the dedicated CRNTI to monitor the control channel. Then, the terminal device receives the downlink data through the data channel scheduled by the control channel, thereby realizing the early transmission of downlink data from the network device to the terminal device.

[0181] Through the examples of the methods executed by the network device in the above-mentioned embodiments, it can be seen that the network device can determine the service indication information corresponding to the data to be processed, the network device can send the service indication information, and the terminal device can send and receive the data to be processed through the service indication information, so that the transmission method or service requirements of the data to be processed are carried by the service indication information. The terminal device can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0182] The above embodiment describes the information processing method provided by the embodiment of the present application from the perspective of the network device. Next, another information processing method performed by the terminal device is introduced. Figure 5 As shown, the embodiment of the present application provides an information processing method, including:

[0183] 501. A terminal device receives service indication information of data to be processed, where the service indication information is used to indicate that the data to be processed is delay sensitive.

[0184] In an embodiment of the present application, the terminal device can receive service indication information from the network device, and the terminal device can determine one or more of the following information based on the service indication information: service type information, service priority information, service delay information, packet transmission indication information, EDT transmission indication information, dedicated resource allocation indication information, and service volume information.

[0185] 502. The terminal device sends and receives data to be processed according to the service instruction information.

[0186] In an embodiment of the present application, a terminal device can receive service indication information, and the terminal device can determine what method to use to send and receive the data to be processed through the service indication information. For example, the data to be processed can be downlink data, and the terminal device can determine the service type information of the downlink data through the service indication information, thereby determining the service type of the downlink data, or obtaining the service priority information, service delay information, and service volume information of the downlink data. Alternatively, the terminal device can also determine whether to use packet transmission or EDT transmission based on the service indication information, or the terminal device can also obtain the dedicated resources allocated by the network device to the terminal device based on the service indication information. In an embodiment of the present application, the needs of communication services with higher latency requirements can be met, and it can be ensured that terminal devices that initiate services with higher latency requirements can access the network first to reduce access latency.

[0187] In some embodiments of the present application, step 502 of the terminal device sending and receiving data to be processed according to the service indication information includes:

[0188] The terminal device determines that the data to be processed is delay-sensitive based on the service type information being the first service type; or, the terminal device determines that the data to be processed is delay-sensitive based on the service priority information being high priority; or, the terminal device determines that the data to be processed is delay-sensitive based on the service delay information being low delay; or, the terminal device determines that the data to be processed is delay-sensitive based on the small packet transmission indication information being the use of a small packet transmission mode; or, the terminal device determines that the data to be processed is delay-sensitive based on the EDT transmission indication information being the use of an EDT transmission mode; or, the terminal device determines that the data to be processed is delay-sensitive based on the dedicated resource allocation indication information being the allocation of dedicated resources; or, the terminal device determines that the data to be processed is delay-sensitive based on the service volume size information being less than or equal to a threshold value;

[0189] When the data to be processed is delay-sensitive, the terminal device uses a small packet transmission mode or an EDT transmission mode to send and receive the data to be processed.

[0190] Among them, when the terminal device determines that the data to be processed is of low latency or high priority, the terminal device can use the small packet transmission mode or the EDT transmission mode to send and receive the data to be processed. Or when the terminal device determines that the core network device instructs to use the small packet transmission mode or the EDT transmission mode, the terminal device can use the small packet transmission mode or the EDT transmission mode to send and receive the data to be processed, or when the terminal device determines that the service type is the specified first service type or the service volume is less than or equal to the threshold, the small packet transmission mode or the EDT transmission mode can be used to send and receive the data to be processed, and the threshold can be determined according to the specific scenario. In an embodiment of the present application, the terminal device can use the small packet transmission mode or the EDT transmission mode to send and receive the data to be processed, so that the processing of the data to be processed can be started quickly, reducing network access and data communication delays.

[0191] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0192] When the data to be processed is low-latency data, or high-priority data, or data transmitted using small packets, or data transmitted using EDT, the terminal device is configured with a backoff strategy and / or a power ramping strategy to reduce the access delay of the terminal device during random access.

[0193] Among them, the terminal device can determine the backoff strategy and power ramping strategy based on the service priority indication information. During the random access process initiated by the terminal device or the paging message triggered by a high-priority service, a smaller backoff parameter can be adopted, or a larger ramping step or a higher ramping frequency can be used. The terminal device has different processing methods for the backoff parameter (BI) and the power ramping parameter (power ramping step). For example, services / events with higher latency requirements back off for a shorter time, or more power ramping is adopted to increase the transmit power of Msg1. For example, after the UE sends a preamble, if it fails to successfully access the network, it will send the preamble again. Power ramping means that the transmit power of the preamble must be increased compared to the transmit power of the previous preamble. The amount of power increase is the ramping step. In addition, if the base station detects a conflict, that is, when too many UEs initiate the random access process on the same resource, the base station sends a BI in the RAR to instruct the UE to back off. Under normal circumstances, the UE generates a random number less than or equal to the BI based on the BI value, and then backs off for the duration corresponding to this random number, thereby spreading out the UE's random access process and reducing concurrency. The backoff strategy allows for a shorter backoff period for random access processes if a UE's service priority warrants network access. Otherwise, the UE can back off according to the normal backoff mechanism, or even for a longer period.

[0194] In some embodiments of the present application, in step 502, the terminal device sends and receives data to be processed according to the service indication information, and may perform the following steps:

[0195] The terminal device obtains resource configuration information indicating dedicated resources;

[0196] The terminal device determines the dedicated random access resource according to the resource configuration information;

[0197] The terminal device uses dedicated random access resources to send a random access request to the network device, and sends and receives data to be processed through RAR messages or RRC commands.

[0198] Among them, the network device can allocate dedicated resources to the terminal device, and the network device can also send resource configuration information to the terminal device. After the terminal device receives the resource configuration information, it can parse the resource configuration information to determine the dedicated random access resource, and the terminal device uses the dedicated random access resource to send a random access request to the network device. The RRC command that the network device can use can specifically be an RRC establishment or reconstruction command, such as "Msg4" or other RRC signaling. When the network device detects the random access process initiated by the terminal device through dedicated resources, it can send downlink data to the terminal device in an RAR message or Msg4, thereby realizing the early transmission of downlink data from the network device to the terminal device.

[0199] In some embodiments of the present application, the aforementioned dedicated resources include dedicated random access resources and / or dedicated CRNTIs. For example, the dedicated random access resources may include dedicated preamble sequences and / or dedicated time-frequency resources. The dedicated random access resources may be allocated in the same manner as the random access resources allocated by the network device for the EDT transmission mode. When the dedicated resource is a dedicated CRNTI, the network device may directly send downlink data to the terminal device using the allocated dedicated CRNTI.

[0200] In some embodiments of the present application, in step 502, the terminal device sends and receives data to be processed according to the service indication information, and may perform the following steps:

[0201] The terminal device obtains resource configuration information indicating dedicated resources;

[0202] The terminal device determines the dedicated CRNTI based on the resource configuration information;

[0203] The terminal device uses a dedicated CRNTI to monitor the control channel;

[0204] The terminal device receives the data to be processed through the data channel scheduled by the control channel.

[0205] For example, the data to be processed is downlink data. The network device can send downlink data to the terminal device through a dedicated CRNTI. The terminal device determines the dedicated CRNTI allocated by the network device based on the service indication message. The terminal device uses the dedicated CRNTI to monitor the control channel. Then, the terminal device receives the downlink data through the data channel scheduled by the control channel, thereby realizing the early transmission of downlink data from the network device to the terminal device.

[0206] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0207] NAS signaling reception status indication information sent by the terminal device through the core network device; or paging message reception status indication information sent by the terminal device through the network device;

[0208] After performing the random access process, the terminal device enters the state indicated by the state indication information.

[0209] Taking downlink data as an example, the core network device may also generate state indication information. Specifically, the core network device uses the state indication information to indicate the state the terminal enters after performing a random access procedure. The terminal device can then use the state indication information to determine the state it should enter after completing the random access procedure. The terminal device can have multiple states, such as an idle state, an access state, or an inactive state. The core network device may send the state indication information in multiple ways. For example, the core network device may send the state indication information to a network device, which then sends the state indication information to the terminal device. The terminal device may receive the state indication information from the core network device or from the network device. For example, the core network device may generate the state indication information based on whether the downlink data requires small packet transmission. When the downlink data requires small packet transmission, the state indication information instructs the terminal device to remain in the idle state after receiving the downlink data. Therefore, the terminal device remains in the idle state or inactive state after receiving the downlink data. When the downlink data does not require small packet transmission, the state indication information instructs the terminal device to enter the connected state after receiving the downlink data. Therefore, the terminal device switches from the idle state or inactive state to the connected state after receiving the downlink data.

[0210] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0211] The terminal device determines the state to be performed after performing the random access process based on the traffic volume information.

[0212] The core network equipment can determine the traffic volume of this communication so that the terminal device can determine whether to enter the connected state or remain in the idle state after completing the random access process using the EDT method. For example, a traffic volume threshold can be set. If the threshold is exceeded, the terminal device enters the connected state; otherwise, the terminal device remains in the idle state.

[0213] In some embodiments of the present application, the information processing method provided in the embodiments of the present application may further perform the following steps:

[0214] The terminal device sends status indication information to the network device, where the status indication information is used to indicate the status entered by the terminal device after sending the data to be processed.

[0215] Among them, for calling services, the data to be processed is uplink data. The terminal device can also send uplink data to the network device, and the terminal device can also generate status indication information, so that the network device can determine the state entered by the terminal device after sending the uplink data based on the status indication information.

[0216] It can be seen from the examples of the method executed by the network device in the above-mentioned embodiment that the terminal device can send and receive the data to be processed through the service indication information, so that the transmission method or service requirement of the data to be processed is carried by the service indication information. The terminal device can quickly start processing the data to be processed through the service indication information, thereby reducing network access and data communication delays.

[0217] In the embodiments of the present application, the information processing method provided in the embodiments of the present application mainly includes the following steps:

[0218] The core network device determines status indication information for the terminal device, where the status indication information is used to indicate the state entered by the terminal device after performing the random access procedure;

[0219] The core network device sends status indication information.

[0220] Among them, the core network device can generate status indication information, that is, the core network device indicates the state entered by the terminal after performing the random access procedure through the status indication information, so that the terminal device can determine the state to be entered after the terminal device completes the random access procedure through the status indication information, where the terminal device can have multiple states, such as idle state, access state, inactive state, etc. The core network device can send the status indication information in multiple ways, such as the core network device sends the status indication information to the network device, and the network device then sends the status indication information to the terminal device.

[0221] An example is given below. The core network device generates status indication information based on the need to use small packet transmission mode for downlink data. When the downlink data needs to be transmitted using the small packet transmission mode, the status indication information is used to instruct the terminal device to remain in an idle state after receiving the downlink data. When the downlink data is not transmitted using the small packet transmission mode, the status indication information is used to instruct the terminal device to enter a connected state after receiving the downlink data.

[0222] Furthermore, in some embodiments of the present application, the core network device sending the status indication information includes:

[0223] The core network device sends status indication information to the terminal device through NAS signaling.

[0224] Optionally, the core network device may also send the status indication information to the network device via a paging message, and the network device may then send the status indication information to the terminal device. For example, a communication connection may be established between the core network device and the network device, and the core network device may send a paging message carrying the status indication information to the network device.

[0225] Among them, the core network device can send a paging message, carrying the status indication information in the paging message, for example, using a reserved field in the paging message to carry the status indication information, or extending a new field in the original paging message to carry the status indication information.

[0226] After receiving the above-mentioned paging message sent by the core network device, the network device sends a paging message carrying the status indication information to the terminal device.

[0227] The status indication information sent by the terminal device through the core network device can determine the state that the terminal device needs to enter after completing the random access process, solving the problem that the terminal device cannot determine which state it should enter after performing the random access process.

[0228] To facilitate a better understanding and implementation of the above solutions in the embodiments of the present application, the following examples are given for specific explanation using corresponding application scenarios.

[0229] Next, taking the use of the embodiment of the present application in the NR application scenario as an example, the EDT transmission mode is used to meet the low latency requirements of delay-sensitive services, such as solving the problem of delay-sensitive downlink data arrival in the called scenario. The embodiment of the present application involves a base station (such as a gNB), a core network device (such as an MME or AMF), and a terminal device (such as a UE).

[0230] Please refer to Figure 6 FIG. 1 is a flow chart of an information processing method according to an embodiment of the present application, which mainly includes the following steps:

[0231] S11. The core network device sends a paging message carrying service indication information.

[0232] When the core network device determines that the UE is in an idle state, if delay-sensitive downlink data is generated, the core network device can generate a paging message for the UE, and carry service indication information in the UE's paging message to indicate the service type or priority that triggers the paging message, or the service indication information can also instruct the UE to access the network using EDT.

[0233] It should be noted that the same downlink service may need to transmit a lot of downlink data. Priority can be a transmission priority issue. For example, the network has so many resources. The data of high-priority services can be sent first, and the data of low-priority services need to wait. Priority can be called access priority in the access stage. In addition, in the embodiment of the present application, "small packet transmission" can be defined as a service. Then EDT is originally for the service of small packet transmission. If low latency is defined as another service, then the EDT transmission method can also be applied to low-latency services.

[0234] S12. The base station determines that low-latency access is required according to the service indication information and determines dedicated random access resources.

[0235] After receiving the paging message from the core network device, the base station determines that it is a paging message triggered by a delay-sensitive service. The paging message sent by the base station may also carry service indication information to indicate the service type or priority that triggered the paging message.

[0236] Optionally, the base station can allocate dedicated random access resources based on the service type or priority indication information in the paging message sent by the core network. Among them, random access includes two categories: one is competitive random access, and this type of random access resources are shared by all UEs, such as random access time and frequency resources, preamble resources, etc. Competition means that the UE will randomly select resources from these resources to initiate a random access process. Since each UE is random, it is possible that two UEs select the same resource. If two UEs select the same resource, the base station can only identify one UE at the same time. This is competition. Because of competition, the access delay may be long. One type is non-competitive random access, which uses dedicated random access resources. Dedicated random access resources are UE-specific. In this way, there will be no conflict and no competition. Because there is no competition, the access delay may be very short.

[0237] It should be noted that the base station can allocate dedicated random access resources based on service indication information. If a service has a high priority and requires rapid network access, dedicated random access resources can be used to access the network, so dedicated random access resources need to be allocated. The base station can include dedicated random access resources in the paging message it sends. Dedicated random access resources include: dedicated preamble and / or dedicated time-frequency resources. For example, dedicated preamble and / or dedicated time-frequency resources can be determined based on the resources allocated by the base station for EDT.

[0238] S13. The base station sends a paging message carrying service indication information and resource configuration information.

[0239] The base station sends a paging message to the UE, and the UE can determine the service indication information and resource configuration information through the paging message.

[0240] Next, the base station and the UE may transmit downlink data in the manner of steps S14 and S15, or in the manner of steps S16 and S17.

[0241] S14. The UE sends a preamble sequence.

[0242] S15. The base station sends downlink data through the RAR.

[0243] S16. UE sends Msg3.

[0244] S17. The base station sends Msg4.

[0245] Among them, after the UE receives the paging message from the base station, if the paging message received by the UE carries service indication information for indicating the service type or priority of the service that triggered the paging message, the UE can determine the service type or priority information of the triggered paging message based on the service indication information, and use the EDT transmission method for random access and data communication.

[0246] Optionally, if the paging message carries a dedicated random access resource, the dedicated random access resource is used to initiate a random access process.

[0247] When the base station detects the random access procedure initiated by the UE using dedicated resources, it can send downlink data to the UE in RAR / Msg4. The UE can determine that the base station will send downlink data in RAR / Msg4 based on the service type and / or priority indication information carried in the paging message that indicates the triggering of the paging message;

[0248] Optionally, after receiving a paging message carrying dedicated random resources sent by the base station and initiating a random access process using the above-mentioned dedicated random access resources, the UE assumes that the base station will send downlink data in RAR / Msg4 and attempts to receive downlink data in RAR / Msg4.

[0249] It should be noted that the gNB can determine whether to allocate dedicated random access resources based on service priority and / or latency requirements, as well as current load. Service priority refers to the priority of the service, which may include service type and priority. Current load refers to the load on the base station, primarily the load on random access resources. Allocating dedicated random access resources for non-contention access reduces resources for contention access, increasing contention. Therefore, if the load is high, allocating dedicated resources is not recommended. Otherwise, allocating dedicated resources can be considered. Latency requirements refer to the latency requirements of the service, and the base station also determines whether to allocate dedicated random access resources based on the latency requirements of the service.

[0250] At the same time, the UE can also determine the backoff strategy and power ramping strategy based on the service type and / or service priority indication information carried in the paging message sent by the base station that triggered the paging message. During the random access process initiated by the UE or the paging message triggered by a high-priority service, a smaller backoff parameter, a larger ramping step size, or a higher ramping frequency can be used.

[0251] In addition, core network equipment can also send paging messages when the terminal device is inactive, reducing the number of participating base stations. This is because reserving dedicated resources consumes air interface resources, and paging messages are broadcast over a large area. If many base stations are involved, it may result in significant resource waste.

[0252] Of course, in combination with the small packet service, if the paging message is triggered by the small packet service, the small packet service can also be indicated in the paging message, so that the UE can also use the EDT solution for the called service. The specific process is similar to the above process and will not be repeated here. What this means is that for the called small packet service, it can also be indicated in the paging message that a downlink small packet service is about to be carried out, and the EDT transmission method can be used. For the calling service, the UE knows what service it is sending and can determine whether to use the EDT transmission method. However, for the called party, the UE does not know what service the network is going to send, so there is no way to determine whether to use EDT. Therefore, the core network equipment needs to use a paging message to tell the UE what service the network is about to send.

[0253] Optionally, status indication information can also be carried in paging messages, such as those sent by core network equipment to a base station and / or by a base station to a UE. This status indication information indicates the UE's state after data transmission based on the EDT scheme, such as whether to remain in the idle state or enter the connected state. For example, if it is a small packet service, the UE may enter the idle state, while a latency-sensitive non-small packet service requires entering the connected state. For the called service, the core network can determine the traffic volume of the current communication, such as whether it is a small packet service and whether there will be subsequent service requirements after the downlink data transmission is completed using RAR / Msg4 based on EDT. Therefore, the paging message sent by the core network equipment to the base station carries status indication information, informing the base station whether the downlink data for this communication can be completed in a single EDT transmission. If a single EDT transmission can be completed, the UE can continue in the idle state after using the EDT transmission method. After obtaining this indication information, the base station can inform the UE whether to enter the connected state or remain in the idle state after the EDT through a paging message sent by the base station. Alternatively, the base station can use Msg4 to tell the UE whether to enter the connected state or remain in the idle state after using the EDT transmission mode. Alternatively, the core network device can directly tell the UE whether to enter the connected state, remain in the idle state, or enter the inactive state after using the EDT transmission mode through a NAS message. Alternatively, the core network device can know the traffic volume of this communication so that the UE can determine whether to enter the connected state or remain in the idle state after using the EDT transmission mode. For example, a traffic volume threshold can be set. If the threshold is exceeded, the UE enters the connected state; otherwise, the UE remains in the idle state.

[0254] Optionally, the base station will indicate the status of the UE after using the EDT transmission mode in Msg4. However, for calling services, the base station actually does not know whether the UE still has data to transmit after EDT. Therefore, the UE tells the base station in Msg3 whether the UE's uplink data can be transmitted completely through EDT. The data transmitted by EDT at one time is limited and predictable. Whether the UE's data can be transmitted completely through EDT at one time can be known, so that the base station can determine the status of the UE after using the EDT transmission mode and notify the UE in Msg4. For example, for an idle UE, this status indication information can be a separate indicator bit. For an inactive or connected UE, it can also be a buffer status report (BSR) information. For called services, the UE can know whether EDT is used, whether it is a called low-latency service or a called small packet service. For calling services, the UE feedbacks information to the base station so that the base station can notify the UE of its status after using the EDT transmission mode in Msg4.

[0255] Please refer to Figure 7 FIG. 1 is a flow chart of another information processing method according to an embodiment of the present application, which mainly includes the following steps:

[0256] S21. The core network device sends a paging message carrying service indication information.

[0257] When the core network device determines that the UE is in an idle state, if delay-sensitive downlink data is generated, the core network device can generate a paging message for the UE, and carry service indication information in the UE's paging message to indicate the service type or priority that triggers the paging message, or the service indication information can also instruct the UE to access the network using EDT.

[0258] It should be noted that the same downlink service may need to transmit a lot of downlink data. Priority can be a transmission priority issue. For example, the network has so many resources. The data of high-priority services can be sent first, and the data of low-priority services need to wait. Priority can be called access priority in the access stage. In addition, in the embodiment of the present application, "small packet transmission" can be defined as a service. Then EDT is originally for the service of small packet transmission. If low latency is defined as another service, then the EDT transmission method can also be applied to low-latency services.

[0259] S22. The base station determines that the service is a low-latency service based on the service indication information.

[0260] After receiving the paging message from the core network device, the base station determines that it is a paging message triggered by a delay-sensitive service. The paging message sent by the base station may also carry service indication information to indicate the service type or priority that triggered the paging message.

[0261] After receiving a paging message from the core network, the base station determines that it is a paging message triggered by a latency-sensitive service, allocates a dedicated identifier, such as a CRNTI, and sends it to the UE, for example, via a paging message. In this way, the base station can directly send downlink data to the UE using the allocated dedicated CRNTI.

[0262] S23. The UE sends a paging message carrying a dedicated CRNTI.

[0263] The UE needs to descramble the physical downlink control channel using a scrambling code (CRNTI, etc.). If the UE can correctly descramble and receive the physical downlink control channel, it can then receive the physical downlink shared channel or send the physical uplink shared channel based on the physical downlink control channel.

[0264] S24. The base station sends the downlink data scrambled by the dedicated CRNTI.

[0265] After receiving the dedicated CRNTI, the UE can use the dedicated CRNTI to monitor the control channel and receive downlink data.

[0266] S25. Obtain a new CRNTI or use the EDT transmission mode to transmit data.

[0267] Optionally, the UE may further initiate a random access procedure. If the random access procedure is successful, the UE may use the new CRNTI generated during the random access procedure to replace the CRNTI previously assigned by the base station. If the random access is successful, the UE will enter the connected state because there will be subsequent data transmission.

[0268] Optionally, the UE may also use the EDT transmission mode to perform the random access process and uplink data transmission.

[0269] Optionally, the core network equipment can also reduce the number of participating base stations by combining the terminal device's inactive state. Because the paging area of an inactive UE is inherently smaller than that of an idle UE, combining the UE's inactivity can reduce the number of base stations. Because reserving CRNTIs occupies air interface resources, and paging messages are broadcast over a large area, involving many base stations can result in significant resource waste.

[0270] It can be seen from the above examples that the embodiment of the present application can start downlink data transmission as soon as possible for delay-sensitive services.
