Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method, device, terminal and network equipment. Background Art

[0002] In the development process from 5G to 6G, Extended Reality (XR) services are introduced, and XR services are expected to become the killer application of 6G. XR services can have many user devices, such as 3D glasses, handle remote controls, etc. There are two basic ways to connect XR services to wireless networks. One is that all user devices are connected to a user equipment (UE, also known as a terminal), and the XR service accesses the wireless network through the terminal. In this way, the same terminal must be used to coordinate the transmission of different streams in an XR service; the other is that different user devices access the wireless network as different terminals. In this way, multiple terminals must be used to coordinate the transmission of different streams in the same XR service.

[0003] Currently, multiple terminals are not supported to coordinate transmission of the same service, and each terminal is accessed independently. Therefore, when the network side initiates a downlink XR service, it is currently not supported for multiple terminals to establish the downlink XR service within the same time range.

[0131] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The information transmission method, device, terminal and network device provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0132] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0133] First, based on the technical solution provided in this application, some technical terms that may be involved are introduced.

[0134] In the existing protocol, there is only a process for establishing a service for a single terminal. When the network side determines to initiate a downlink service, the core network initiates a paging message for a single terminal and sends it to all base stations in the Tracking Area (TA). These base stations send air interface paging messages in the cells included in the TA. The paging message carries the User Equipment (UE) identifier. After receiving the paging message, the terminal initiates a connection establishment process (terminals in the Radio Resource Control Idle (RRC_IDLE) state) or a connection recovery process (terminals in the Radio Resource Control Inactive (RRC_INACTIVE) state) to the base station, and after entering the connected state, it performs service establishment and subsequent service transmission processes.

[0135] Based on the analysis, the embodiments of the present application provide an information transmission method, apparatus, terminal, and network device to ensure support for multiple terminals to establish XR services within the same time range.

[0136] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0137] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, which is executed by a first network device and includes:

[0138] Step S201, in the case of initiating a target service corresponding to at least two terminals, sending a first paging message to the at least two terminals;

[0139] Wherein, the first paging message carries a service identifier and / or a terminal group identifier of a target service.

[0140] It should be noted that the terminal group indicated by the terminal group identifier is associated with the target service. Optionally, the at least two terminals mentioned above are terminals in the terminal group.

[0141] Optionally, the target service referred to in the embodiment of the present application refers to an XR service.

[0142] It should be noted that in an embodiment of the present application, when the first network device determines that it is necessary to initiate a target service corresponding to at least two terminals, it is necessary to send a first paging message to the at least two terminals. The first paging message can be called an air interface paging message. It should be noted that the first paging message can be sent to at least two terminals at the same time, or it can be sent to different terminals within a time range. Ultimately, it can achieve the goal of enabling multiple terminals to establish target services at the same time and realize communication between multiple terminals for the target service at the same time, for example, realizing communication between multiple terminals for downlink XR services at the same time.

[0143] Optionally, in an implementation manner, if the first paging message carries only a terminal group identifier, the terminals included in the terminal group indicated by the terminal group identifier are all terminals associated with the target service.

[0144] Optionally, in one implementation, the service identifier of the target service is used to indicate at least one of the following:

[0145] A11, Class I business;

[0146] For example, when the target service is an XR service, the service identifier is used to indicate the XR service.

[0147] A12. A type of business under a type of business;

[0148] It should be noted that, in this case, the service identifier indicates a specific service under a category of services, and the specific service may be a data transmission service, a data processing service, etc. For example, when the target service is an XR service, the service identifier is used to indicate a service under the XR service.

[0149] Optionally, in an implementation manner, the sending a first paging message to the at least two terminals includes:

[0150] Sending a paging message indication to the second network device, where the paging message indication is used to instruct the second network device to send a first paging message to the terminal within the coverage area, and the paging message indication carries a service identifier and / or a terminal group identifier of the target service;

[0151] receiving a first response message sent by the second network device;

[0152] A first paging message is sent to at least one terminal among the at least two terminals according to the first response message.

[0153] The second network device and the first network device are in the same radio access network notification area (RAN-based Notification Area, RNA).

[0154] It should be noted here that this situation refers to when the first network device cannot determine that all terminals that need to perform the target service are completely within its coverage area (this situation is usually when the terminal is in the RRC inactive state), it is necessary to page within a determined predefined area, and all network devices within the area must participate in the paging, and the area is the wireless access network notification area. Therefore, the first network device must send a paging message indication to other network devices in the RNA so that other network devices and the first network device can cooperate to perform paging of multiple terminals. Optionally, in one case, after receiving the first response message sent by the second network device, the first network device begins to send the first paging message to the terminals within its coverage area; and after sending the first response message, the second network device can send the first paging message to the terminals within its coverage area. Optionally, in another case, the first network device can also directly send the first paging message, that is, the process of the first network device sending the paging message is independent of the process of the first network device interacting with the second network device.

[0155] For example, the first network device determines that it needs to initiate target services corresponding to five terminals, but only terminal A is within the coverage of the first network device, while terminal B, terminal C, terminal D and terminal E are within the coverage of the second network device. The first network device needs to send a paging message indication to the second network device, so that the second network device initiates paging to terminal B, terminal C, terminal D and terminal E, so that terminal A, terminal B, terminal C, terminal D and terminal E all establish the target service.

[0156] Optionally, in one implementation, the first response message may establish a response message for the target service.

[0157] Optionally, in one implementation, the paging message indication further carries at least one of the following:

[0158] A21, terminal identification corresponding to the target service;

[0159] A22, sub-business identifier of the target business;

[0160] It should be noted that a sub-business can be understood as a specific business under the target business.

[0161] A23. Terminal identifier corresponding to the sub-service of the target service.

[0162] Optionally, in an implementation manner, before sending the first paging message to the at least two terminals, the method further includes:

[0163] Receiving a second paging message sent by the core network device;

[0164] The first paging message is sent to the at least two terminals according to the second paging message.

[0165] It should be noted that this situation can be understood as: when there is a data transmission demand for the target service on the core network side, it is necessary to first send a second paging message to the first network device to page the terminal under the first network device. When the first network device receives the second paging message sent by the core network device, it can send a first paging message to the terminal within the coverage area to page the terminal within the coverage area and establish a connection with the core network device. This situation is mainly applicable to the establishment of the target service of the terminal in the RRC_IDLE state.

[0166] Optionally, the second paging message includes at least one of the following:

[0167] A31, business identification of the target business;

[0168] For example, the service identifier may be a service number, a service index, etc.

[0169] A32, terminal identification corresponding to the target service;

[0170] For example, the terminal identifier can be the terminal's 5G S-Temporary Mobile Subscription Identifier (5G-S-TMSI).

[0171] A33, terminal group identifier corresponding to the target service;

[0172] A34, sub-business identifier of the target business;

[0173] Optionally, in one implementation, the sub-service identifier includes at least one of the following:

[0174] Sub-service number, flow ID, sub-flow ID.

[0175] A35, terminal identifier corresponding to the sub-service of the target service;

[0176] A36. Terminal group identifier corresponding to the sub-service of the target service.

[0177] Optionally, in an implementation manner, after sending the first paging message to the at least two terminals, the method further includes:

[0178] A first request message sent by at least one of the at least two terminals is received, wherein the first request message carries at least one of the following: a service identifier of a target service, a sub-service identifier of the target service, a terminal identifier, a terminal group identifier, and a request reason.

[0179] Optionally, the request reason is used to indicate establishment or restoration of services of at least two terminals.

[0180] Optionally, the first request message may be an RRC connection establishment request message or an RRC recovery request message. In the case of an RRC connection establishment request message, the request cause is used to indicate establishment of at least two terminal services; in the case of an RRC recovery request message, the request cause is used to indicate recovery of at least two terminal services.

[0181] Optionally, in an implementation manner, the manner in which the terminal sends the first request message to the first network device includes at least one of the following:

[0182] B11. If the service identifier of the target service carried in the first paging message indicates a type of service and the terminal is a terminal executing the target service, send the first request message to the first network device;

[0183] This situation can be understood as, if the first paging message is used to indicate the target service, and the terminal determines by itself that it needs to execute the target service, then at this time the terminal needs to send a first request message to the first network device.

[0184] B12. If the first paging message carries a terminal group identifier, and the terminal is a terminal in the terminal group corresponding to the terminal group identifier, sending the first request message to the first network device;

[0185] This situation can be understood as, if the terminal receives the first paging message, and the terminal group indicated by the first paging message is the terminal group to which the terminal belongs, then the terminal needs to send a first request message to the first network device.

[0186] B13. If it is determined that the service supported by the terminal matches a type of service or a type of service under a type of service indicated by the service identifier of the target service carried in the first paging message, sending the first request message to the first network device;

[0187] This situation can be understood as, if the terminal receives a first paging message indicating a specific service under the target service, and the terminal supports the service, the terminal needs to send a first request message to the first network device; or, if the terminal receives a first paging message indicating the target service, and the terminal supports the target service, the terminal needs to send a first request message to the first network device.

[0188] Further optionally, in an implementation manner, after receiving the first request message sent by at least one terminal of the at least two terminals, the method further includes:

[0189] If at least one of the at least two terminals is associated with the target service or terminal group, establishing or restoring a radio bearer corresponding to the target service or terminal group for at least one of the at least two terminals;

[0190] A second response message is sent to the terminal.

[0191] It should be noted here that the association between the terminal and the target service or terminal group can be understood as that the first network device side stores the correspondence between the target service and the terminal, or the correspondence between the terminal group and the terminal, and the correspondence can be reflected through a terminal list, and the terminals included in the terminal list are associated with the target service or terminal group.

[0192] Optionally, the second response message includes radio bearer information corresponding to the target service and / or configuration information of the radio bearer corresponding to the target service.

[0193] Optionally, the radio bearer information may include: a radio bearer identifier (DRB ID), a default radio bearer or an activated stored radio bearer; the specific radio bearer corresponding to the radio bearer information may be pre-stored and configured in the base station and the terminal.

[0194] Optionally, the configuration information of the radio bearer may include: a radio bearer identifier (DRB ID) and configurations of each protocol layer corresponding to the radio bearer.

[0195] Optionally, in one implementation, the first request message is a radio resource control (RRC) connection establishment request message, and the second response message is an RRC connection establishment message; or

[0196] The first request message is an RRC recovery request message, and the second response message is an RRC connection establishment message or an RRC connection recovery message.

[0197] The following takes the communication between the terminal and the base station to perform the XR service as an example to illustrate the specific implementation of the embodiment of the present application as follows.

[0198] Application Scenario 1: Paging initiated by the core network side

[0199] like Figure 3 As shown in the figure, the main implementation process includes:

[0200] Step 300: The first base station pre-stores relevant information of the XR service, including the XR service identifier and the terminal identifier;

[0201] Optionally, sub-service information corresponding to the XR service on different terminals is also included.

[0202] It should be noted that step 300 is an optional step.

[0203] Step 301: The first base station receives a second paging message sent by a core network device;

[0204] Optionally, the second paging message carries: 1) a service identifier of the XR service, which is specifically used to indicate all XR services (i.e., not for a specific XR service, all XR service UEs must respond when receiving the paging message) or a specific service under the XR service (i.e., the XR service identifier of the specified XR service (such as Common ID)); 2) if step 300 is not performed, that is, the first base station does not store information related to the XR service, the first paging message sent by the core network device may also carry a terminal identifier corresponding to the XR service, and / or a sub-service identifier of the XR service corresponding to the terminal, where the sub-service identifier may be a sub-service ID, a flow identifier (flow ID), or a sub-flow identifier (sub-flow ID).

[0205] Step 302: The first base station sends a first paging message over an air interface. The first paging message carries a service identifier of the XR service.

[0206] Step 303: The terminal determines the service identifier of the XR service carried in the first paging message according to the received first paging message.

[0207] Step 304: If the XR service is related to the terminal, an RRC connection establishment request message is initiated to the first base station;

[0208] Optionally, this step may be implemented by at least one of the following:

[0209] C11. If the terminal is an XR service terminal, the service identifier of the XR service carried in the first paging message is used to indicate all XR services (i.e., not for a specific XR service, all XR service UEs receiving the paging message must respond), and an RRC connection establishment process is initiated to the first base station. Optionally, the service identifier of the XR service is carried in the RRC connection establishment request message, which is used to indicate all XR services or a specific service under the XR service; or, an XR sub-service identifier;

[0210] C12. If the terminal can determine the specific XR service it supports (i.e., determine the service identifier (such as Common ID) of the specific XR service it supports), and the service identifier carried in the first paging message sent by the first base station matches the XR service identifier supported by the terminal, the terminal initiates an RRC connection establishment process to the first base station. Optionally, the RRC connection establishment request message carries the service identifier of the specific XR service, or the sub-service identifier of the specific XR service.

[0211] Step 305: If the terminal that initiates the RRC connection establishment request message is in the list of terminals associated with the XR service, the first base station determines to establish a radio bearer related to the XR service for the terminal;

[0212] Step 306: Send an RRC connection establishment message to the terminal;

[0213] The RRC connection establishment message carries radio bearer information and / or configuration information of the radio bearer corresponding to the target service.

[0214] It should be noted that Figure 3 The communication process between the second base station and the core network device and the terminal is similar to that of the first base station, and will not be repeated here. The communication process between the second base station and the core network device and the terminal and the communication process of the first base station can be carried out simultaneously.

[0215] Application scenario 2: Paging initiated by the base station side

[0216] like Figure 4 As shown in the figure, the main implementation process includes:

[0217] Step 400: The first base station pre-stores relevant information of the XR service, including an XR service identifier and a terminal identifier;

[0218] Optionally, it also includes sub-service information corresponding to the XR service under different terminals. In the existing protocol, when the terminal enters the inactive state, the base station needs to save the terminal context. Based on this basic process, the difference of this application is that the terminal context that needs to be saved on the base station side also includes XR service-related context information.

[0219] It should be noted that step 400 is an optional step.

[0220] Step 401: If the terminal related to the XR service is under the second base station, a paging message indication is sent to the second base station;

[0221] Optionally, the paging message indication may be understood as an XR establishment notification, or a notification of initiating RAN-side paging, and the paging message indication carries an XR service identifier and / or an XR service-related terminal identifier.

[0222] Step 402: Receive a first response message fed back by the second base station;

[0223] Optionally, the first response message may be referred to as an XR service establishment response, or as a RAN side paging response, which determines that the second base station under the RAN paging area is to send the first paging message together.

[0224] Step 403: The base station sends a first paging message over the air interface. The first paging message carries a service identifier of the XR service.

[0225] Step 404: The terminal determines the XR service identifier carried in the first paging message according to the received first paging message.

[0226] Step 405: If the XR service is related to the terminal, an RRC recovery request message is sent to the base station;

[0227] Optionally, this step may be implemented by at least one of the following:

[0228] C21. If the terminal is an XR service terminal, the service identifier of the XR service carried in the first paging message is used to indicate all XR services (i.e., not for a specific XR service, all XR service UEs receiving the paging message must respond), and an RRC connection recovery process is initiated to the base station. Optionally, the service identifier of the XR service in the RRC recovery request message is used to indicate all XR services or a specific service under the XR service; or, an XR sub-service identifier;

[0229] C22. If the terminal can determine the specific XR service it supports (i.e., determine the service identifier (such as Common ID) of the specific XR service it supports), and the service identifier carried in the first paging message sent by the base station matches the XR service identifier supported by the terminal, the terminal initiates an RRC connection recovery process to the base station. Optionally, the RRC recovery request message carries the service identifier of the specific XR service, or the sub-service identifier of the specific XR service.

[0230] Step 406: If the terminal that initiates the RRC recovery request message is in the list of terminals associated with the XR service, the base station determines to establish a radio bearer related to the XR service for the terminal;

[0231] Step 407: Send an RRC connection establishment message or an RRC connection recovery message to the terminal;

[0232] The RRC connection establishment message or the RRC connection recovery message carries the radio bearer information and / or the configuration information of the radio bearer corresponding to the target service.

[0233] It should be noted that Figure 4 The first base station needs to send a first paging message to the terminals within its coverage, and the terminals within the coverage of the first base station also send RRC recovery request messages to the first base station; the second base station needs to send a first paging message to the terminals within its coverage, and the terminals within the coverage of the second base station also send RRC recovery request messages to the second base station.
