Description

Technical Field

[0002] In wireless communication systems, resource allocation is a very important part of the base station's work, which is related to whether the base station and UE (English: User Equipment; Chinese: User Equipment) can communicate normally. When allocating downlink resources, the base station knows whether there is downlink data, so it can directly allocate it. When allocating uplink resources, if the base station knows that a certain service process requires the UE to respond uplink, it will generally actively allocate uplink resources to the UE without waiting for the UE to apply to the base station for uplink resource allocation.

[0003] However, the current base station actively allocating uplink resources to the UE has certain limitations, resulting in the UE needing to apply to the base station for allocation of uplink resources in some cases, thereby affecting communication latency. Summary of the invention

[0067] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] In wireless communication systems, resource allocation is a very important work link of the base station, which is related to whether the base station and UE (English: User Equipment; Chinese: User Equipment) can communicate normally. When allocating downlink resources, the base station knows whether there is downlink data, so it can directly allocate. When allocating uplink resources, the base station generally cannot predict when the UE needs to perform uplink transmission. Therefore, it is usually necessary for the UE to actively apply for uplink resources from the base station when there is an uplink transmission demand. The base station allocates uplink resources to the UE based on the UE's application. However, if the base station knows that a certain service process requires the UE to respond uplink, it will generally actively allocate uplink resources to the UE without waiting for the UE to apply to the base station for allocation of uplink resources.

[0069] However, the base station's active allocation of uplink resources to the UE is limited to service processes that the base station itself can identify. For service processes that the base station cannot identify, the base station cannot determine whether the service process requires the UE to make an uplink response. Therefore, the base station cannot actively allocate uplink resources to the UE.

[0070] In actual applications, the service processes that the base station can recognize may include, for example, many service processes of the RRC (Radio Resource Control) protocol, and the service processes that the base station cannot recognize may include, for example, many service processes involving NAS (Non-Access Stratum) messages.

[0071] Since the base station cannot actively allocate uplink resources to the UE for the service processes that it cannot recognize, the base station needs to apply to the base station for allocation of uplink resources before making an uplink response during these service processes. The base station will allocate uplink resources to the UE only after receiving the UE's application, which will affect the communication delay to a certain extent.

[0072] In view of this, an embodiment of the present application provides a resource allocation method, in which, for a service process involving NAS messages that cannot be recognized by the base station, the base station can actively allocate uplink resources to the UE, thereby reducing the communication delay of the service process involving NAS messages.

[0073] Please refer to Figure 1 , which shows a schematic diagram of the implementation environment involved in the resource allocation method provided in the embodiment of the present application, such as Figure 1As shown, the implementation environment may include UE 101, base station 102 and AMF (English: Access and Mobility management Function; Chinese: Access and Mobility Management Function) 103, wherein UE 101 and base station 102 perform data transmission through the network, and base station 102 and AMF 103 perform data transmission through the network.

[0074] It should be pointed out that the resource allocation method provided in the embodiment of the present application can be applied to a terrestrial wireless communication system or a satellite communication system. In a satellite communication system, in one possible deployment scheme, the base station 102 can be deployed on a satellite. In another possible deployment scheme, the base station 102 can be deployed on the ground, and the satellite serves as a transit device to realize data transmission between the base station 102 and the UE 101.

[0075] It should be noted that the UE involved in the embodiments of the present application may be a wireless terminal, which may be a device that provides voice and / or other business data connectivity to a user, or a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal may be a USB storage device, other personal computer memory devices, and a dongle, or may communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device, which exchanges language and / or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDA), personal computers, tablet computers, Machine-type Communication (MTC) terminal devices, etc. Wireless terminals can also be called systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal equipment, access terminal equipment, user terminal equipment, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, which are not limited in the embodiments of the present application.

[0076] The base station involved in the embodiment of the present application may include multiple cells that provide services for wireless terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The base station involved in the embodiment of the present application may be a 5G base station (gNB) in the 5G network architecture (English: next generation system), or may be a home evolved Node B (English: Home evolved Node B; abbreviated: HeNB), a relay node (English: relay node), a home base station (English: femto), a micro base station (English: pico), a network test device, etc., which is not limited in the embodiment of the present application. In some network structures, the base station may include a centralized unit (English: centralized unit; abbreviated: CU) node and a distributed unit (English: distributed unit; abbreviated: DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0077] The AMF involved in the embodiment of the present application is deployed in the 5G core network, which is one of the most important network functions in the 5G core network. Its functions include registration management, connection management and mobility management, which is similar to the MME (English: Mobility Management Entity; Chinese: Mobility Management Entity) in the LTE (English: long term evolution; abbreviated as: long term evolution) core network.

[0078] In actual applications, AMF can send NGAP (Next Generation Application Protocol) messages to the base station, where the NGAP messages can include PDU session management messages, paging messages, NAS messages, etc.

[0079] For NAS messages in NGAP messages, the base station will transparently forward them to the UE, that is, the base station will not parse the NAS message, but only forward it to the UE. Since the base station does not parse the NAS message, the base station cannot identify the NAS message, and therefore cannot determine whether the UE needs to respond to the NAS message uplink. In this case, the base station cannot actively allocate uplink resources to the UE, which results in a large communication delay for the service process involving the NAS message.

[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0081] Please refer to Figure 2 In an exemplary embodiment, a resource allocation method is provided, wherein the method is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, and the following steps are included:

[0082] Step 201: The base station receives the NGAP message sent by the AMF.

[0083] As described above, NGAP messages can be transmitted between the base station and the AMF, where the NGAP messages can include multiple contents, such as PDU session management messages, paging messages, NAS messages, configuration information, etc.

[0084] Step 202: If it is determined based on the NGAP message that the UE needs to make an uplink response to the NAS message in the NGAP message, the base station allocates uplink resources to the UE.

[0085] In the traditional method, the base station transparently forwards the NAS message in the NGAP. Therefore, the base station cannot identify the NAS message, and therefore cannot determine whether the UE needs to make an uplink response to the NAS message. In this case, the base station cannot actively allocate uplink resources to the UE, but needs to wait until the UE receives the NAS message and determines that it needs to make an uplink response to the NAS message. The UE applies for uplink resources from the base station, and the base station will allocate uplink resources to the UE based on the UE's application.

[0086] In the embodiment of the present application, the NGAP message can indicate whether the NAS message contained therein requires the UE to perform an uplink response. Therefore, although the base station still transparently forwards the NAS message, that is, the base station still cannot identify the NAS message, the base station can determine whether the UE needs to perform an uplink response to the NAS message in the NGAP message based on the NGAP message. In this way, when the UE needs to perform an uplink response to the NAS message in the NGAP message, the base station can actively allocate uplink resources to the UE without waiting for the UE's application.

[0087] In the resource allocation method provided in this embodiment, after receiving the NGAP message sent by the AMF, if the base station determines based on the NGAP message that the UE needs to make an uplink response to the NAS message in the NGAP message, the base station allocates uplink resources to the UE. In this way, for the NAS message, the base station can determine based on the NGAP message whether the UE needs to make an uplink response to the NAS message, and actively allocate uplink resources to the UE when it is determined that the UE needs to make an uplink response to the NAS message, without waiting for the UE to apply to the base station for allocation of uplink resources before allocating uplink resources to the UE, thereby reducing the communication delay of the business process involving the NAS message.

[0088] In particular, for satellite communication systems, due to their long communication distance and long time, the processing flow should be simplified as much as possible to avoid excessive round-trips between UE and base station to reduce communication delay. The technical solution provided in the embodiment of the present application can enable the base station to actively allocate uplink resources for the uplink response of the NAS message without waiting for the UE to apply. Therefore, the communication delay can be reduced, which has a significant effect on improving the performance of the satellite communication system.

[0089] In one embodiment of the present application, after receiving the NGAP message sent by the AMF, the base station may first detect whether there is a NAS message in the NGAP message. If there is no NAS message, the base station may not perform the above step 202. If there is a NAS message, the base station may perform the above step 202, so as to actively allocate the uplink resources required for the uplink response to the UE when the NAS message in the NGAP message requires the UE to perform an uplink response. In this way, the base station can perform step 202 only when necessary, thereby reducing the processing delay of the base station and then reducing the communication delay as a whole.

[0090] In an optional embodiment of the present application, a new NGAP parameter may be defined in the NGAP message. The NGAP parameter may be called an uplink transmission parameter (English: UL data to be transmitted), for example. The uplink transmission parameter is used to indicate that the UE needs to make an uplink response.

[0091] In an optional embodiment of the present application, if the uplink transmission parameter exists in the NGAP message, it means that the NAS message in the NGAP message requires the UE to perform an uplink response. Conversely, if the uplink transmission parameter does not exist in the NGAP message, it means that the NAS message in the NGAP message does not require the UE to perform an uplink response.

[0092] After receiving the NGAP message sent by the AMF, the base station can detect whether the NGAP message contains the uplink transmission parameters. If so, the base station determines that the UE needs to make an uplink response to the NAS message in the NGAP message. In this case, the base station can actively allocate uplink resources to the UE. If not, the base station determines that the UE does not need to make an uplink response to the NAS message in the NGAP message. In this case, the base station may not actively allocate uplink resources to the UE.

[0093] Of course, in an optional embodiment of the present application, after receiving the NGAP message sent by the AMF, the base station can first detect whether there is a NAS message in the NGAP message. If there is a NAS message, the base station will then execute the step of detecting whether the NGAP message contains the uplink transmission parameters, so as to ensure that the base station will execute the step of detecting whether the NGAP message contains the uplink transmission parameters only when necessary, thereby reducing the processing delay of the base station and then reducing the communication delay as a whole.

[0094] In an optional embodiment of the present application, when determining that the NGAP message contains uplink transmission parameters, the base station can send DCI (Downlink Control Information) to the UE to allocate uplink resources to the UE, wherein the DCI is used to indicate the uplink resources allocated to the UE, and optionally, the DCI can indicate the time-frequency position of the uplink resources allocated to the UE.

[0095] Please refer to Figure 3 In an exemplary embodiment, a resource allocation method is provided, wherein the method is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, and the following steps are included:

[0096] Step 301: The base station receives the NGAP message sent by the AMF.

[0097] Step 302: The base station parses the received NGAP message to determine whether it is necessary to trigger the sending of a downlink RRC message. If not, the process ends; if so, jumps to step 303.

[0098] Step 303: The base station allocates downlink resources and sends a first DCI to the UE to indicate the downlink resources allocated by the base station to the UE through the first DCI. The base station sends a downlink RRC message to the UE through the allocated downlink resources, which may include a NAS message.

[0099] Step 304: When determining that there is a NAS message in the NGAP message, the base station determines whether there is an uplink transmission parameter in the NGAP message. If not, the process ends; if so, step 305 is executed.

[0100] Step 305: The base station allocates uplink resources to the UE and sends a second DCI to the UE, so as to indicate to the UE through the second DCI the uplink resources allocated by the base station to the UE, and the uplink resources are used by the UE to send an uplink response message to the NAS message to the base station.

[0101] Please refer to Figure 4 In an exemplary embodiment, a resource allocation method is provided, wherein the method is applied to Figure 1 The AMF in the example is used to illustrate, including the following steps:

[0102] Step 401: AMF determines that the NAS message to be sent requires an uplink response from the UE.

[0103] Since the sender of the NAS message is the AMF, the AMF can identify the NAS message and determine whether the NAS message requires the UE to perform an uplink response. If it is determined that the NAS message requires the UE to perform an uplink response, step 402 can be executed.

[0104] Step 402: AMF generates a NGAP message based on the NAS message, where the NGAP message is used to indicate that the UE needs to make an uplink response.

[0105] Optionally, when the AMF determines that the NAS message requires the UE to make an uplink response, the AMF may generate an NGAP message based on the NAS message to indicate that the UE needs to make an uplink response. Conversely, when the AMF determines that the NAS message does not require the UE to make an uplink response, the AMF may generate an NGAP message based on the NAS message to indicate that the UE does not need to make an uplink response.

[0106] It should be noted that the embodiment of the present application does not limit the message type of the NGAP message. For example, the NGAP message may be a downlink NAS transport message (English: DOWNLINK NAS TRANSPORT) message, or an initial context setup request (English: Initial Context Setup Request) message.

[0107] Step 403: AMF sends the generated NGAP message to the base station.

[0108] The resource allocation method provided in this embodiment, when it is determined that the NAS message to be sent requires the UE to perform an uplink response, the AMF can generate an NGAP message for indicating that the UE needs to perform an uplink response based on the NAS message, and then send the NGAP message to the base station. In this way, for the NAS message that requires the UE to perform an uplink response, the base station can determine that the UE needs to perform an uplink response to the NAS message based on the received NGAP message, and when it is determined that the UE needs to perform an uplink response to the NAS message, the base station actively allocates uplink resources to the UE without waiting for the UE to apply to the base station for allocation of uplink resources before allocating uplink resources to the UE, thereby reducing the communication delay of the business process involving the NAS message.

[0109] As described above, in an optional embodiment of the present application, a new NGAP parameter may be defined in the NGAP message, and the NGAP parameter may be called an uplink transmission parameter, for example, wherein the uplink transmission parameter is used to indicate that the UE needs to make an uplink response.

[0110] Optionally, when the AMF determines that the NAS message to be sent requires an uplink response from the UE, the AMF may package the uplink transmission parameters and the NAS message together into an NGAP message to indicate to the base station that the NAS message in the NGAP message requires an uplink response from the UE. Conversely, when the AMF determines that the NAS message to be sent does not require an uplink response from the UE, the AMF may package the NAS message into the NGAP message without packaging the uplink transmission parameters, thereby indicating to the base station that the NAS message in the NGAP message does not require an uplink response from the UE.

[0111] In actual applications, NAS messages are generated at the NAS protocol layer of AMF, and NGAP messages are packaged at the NGAP protocol layer of AMF. Therefore, in an embodiment of the present application, it is necessary to transfer information between the NAS protocol layer and the NGAP protocol layer to inform the NGAP protocol layer whether the NAS message requires the UE to perform an uplink response, so that the NGAP protocol layer selects the packaging method of the NGAP message.

[0112] Optionally, an embodiment of the present application newly defines an indication message between the NAS protocol layer and the NGAP protocol layer, and the indication message may be called uplink response requirement information (English: UL data response needed). If the NAS protocol layer in the AMF determines that the NAS message requires the UE to perform an uplink response, it may pass the uplink response requirement information to the NGAP protocol layer in the AMF, thereby notifying the NGAP protocol layer that the NAS message requires the UE to perform an uplink response. Conversely, if the NAS protocol layer determines that the NAS message does not require the UE to perform an uplink response, it may not pass the uplink response requirement information to the NGAP protocol layer. If the NGAP protocol layer does not receive the uplink response requirement information passed by the NAS layer, the NGAP protocol layer may determine that the NAS message does not require the UE to perform an uplink response.

[0113] In an optional embodiment of the present application, the NGAP protocol layer may select an NGAP message packing method based on whether it has received the uplink response requirement information transmitted by the NAS protocol layer. Optionally, the NGAP protocol layer may pack the uplink transmission parameters and the NAS message into the NGAP message together when it has received the uplink response requirement information transmitted by the NAS protocol layer. The NGAP protocol layer may also pack the NAS message into the NGAP message without packing the uplink transmission parameters when it has not received the uplink response requirement information transmitted by the NAS protocol layer.

[0114] Please refer to Figure 5 In an exemplary embodiment, a resource allocation method is provided, wherein the method is applied to Figure 1 The AMF in the example is used to illustrate, including the following steps:

[0115] Step 501: The NAS protocol layer in the AMF determines whether the NAS message to be sent requires an uplink response from the UE. If so, execute steps 502 and 503; if not, execute 504.

[0116] Step 502: The NAS protocol layer transmits the uplink response request information to the NGAP protocol layer.

[0117] Step 503 : Upon receiving the uplink response requirement information, the NGAP protocol layer packages the NAS message and the uplink transmission parameters into the NGAP message, and jumps to step 505 .

[0118] Step 504 : If the NGAP protocol layer does not receive the uplink response request information, the NGAP protocol layer packages the NAS message into the NGAP message and jumps to step 505 .

[0119] Step 505: AMF sends the NGAP message to the base station.

[0120] It should be pointed out that in actual applications, there are many business processes involving NAS messages, such as identity identification process, authentication process, encryption process, security mode control process, etc. Correspondingly, there are many types of NAS messages, such as authentication request message (English: Authentication request), etc. The embodiments of the present application do not make specific limitations on this.

[0121] In order to make it easier for readers to understand the technical solution provided by the embodiment of the present application, the embodiment of the present application will take the identity recognition process as an example to illustrate the technical solution provided by the embodiment of the present application. Please refer to Figure 6 , the identity recognition business process includes the following steps:

[0122] Step 601, UE601 sends a random access message 1: UE monitors the SSB (English: Synchronization Signal Block; Chinese: Synchronization Signal Block) and system information in the signaling beam, selects preamble (Chinese: Random Access Preamble) and PRACH (English: Physical Random Access Channel; Chinese: Physical Random Access Channel) resources, and uses the PRACH resources to send the selected preamble to the base station.

[0123] Step 602, the base station sends a random access message 2: After the UE sends the preamble, it starts a RAR (English: random access response; Chinese: random access response) window (Chinese: window) after a specific offset, and monitors the DCI that schedules the RAR within the RAR window, and receives the RAR sent by the base station based on the monitored DCI.

[0124] Step 603, UE sends random access message 3: UE sends message 3 according to UL grant (Chinese: uplink authorization) in message 2. It should be noted that the message 3 corresponding to the random access triggered by different random access reasons is different. For example, message 3 can be RRC Setup Request (Chinese: RRC establishment request) or RRC Resume Request (Chinese: RRC recovery request). In this example, it is RRC Setup Request.

[0125] Step 604, the base station sends a random access message 4: After monitoring the DCI on the PDCCH (English: Physical Downlink Control Channel; Chinese: Physical Downlink Control Channel), the UE determines the PDSCH (English: Physical Downlink Shared Channel; Chinese: Physical Downlink Shared Channel) resource according to the DCI, and then receives message 4 on the PDSCH resource. The message 4 includes RRC Setup (Chinese: RRC establishment message) and also includes an identifier for contention resolution.

[0126] Step 605, the UE feeds back HARQ (English: Hybrid Automatic Repeat Request; Chinese: Hybrid Automatic Repeat Request) ACK information of message 4 to the base station: After successfully receiving and decoding message 4, the UE submits message 4 to the high-level protocol stack and feeds back HARQ ACK information to the base station.

[0127] Step 606, the UE sends a message 5 to the base station: After the high-level protocol stack of the UE receives the message 4, if the contention is resolved successfully, it monitors the PDCCH to obtain the DCI, thereby determining the transmission resource of the message 5, and then transmits the message 5 through the transmission resource. The message 5 is the RRC Setup Complete (Chinese: RRC setup completion message), and the message 5 will carry the Registration request (Chinese: registration request) of the NAS protocol layer.

[0128] Step 607: The base station sends an Initial UE Message to the AMF. The Initial UE Message includes a Registration request of the NAS protocol layer.

[0129] Step 608, the NAS protocol layer in the AMF transmits information to the NGAP protocol layer: the NAS protocol layer analyzes the status of the current process. If there is no identity information of the UE, it is necessary to initiate an identity identification process. During the identity identification process, the NAS protocol layer transmits the Identity request (Chinese: Identity Identification Request) to the NGAP protocol layer, wherein the Identity request is a NAS message. The NAS protocol layer determines that the Identity request requires an uplink response from the UE. Therefore, the NAS protocol layer transmits the uplink response requirement information to the NGAP protocol layer to notify the NGAP protocol layer that the Identity request requires an uplink response from the UE.

[0130] Step 609, AMF sends DOWNLINK NAS TRANSPORT to the base station: After the NGAP protocol layer in the AMF receives the Identity request and uplink response requirement information transmitted by the NAS protocol layer, it packages the Identity request and the uplink transmission parameters into the DOWNLINK NAS TRANSPORT, where the DOWNLINK NAS TRANSPORT is an NGAP message, and the uplink transmission parameters are used to indicate that the Identity request requires the UE to perform an uplink response.

[0131] Step 610: The base station sends a first DCI and DLInformationTransfer (Chinese: downlink message transmission) to the UE: the first DCI is used to indicate the downlink resources for transmitting the DLInformationTransfer, and the DLInformationTransfer includes an Identity request message.

[0132] Step 611, the base station sends a second DCI to the UE: after parsing the DOWNLINK NAS TRANSPORT, the base station determines that the DOWNLINK NAS TRANSPORT includes uplink transmission parameters, then the base station actively allocates uplink resources to the UE, and sends a second DCI to the UE to indicate the uplink resources actively allocated by the base station to the UE.

[0133] Step 612, the UE sends a ULInformationTransfer (Chinese: uplink message transmission) to the base station: the UE determines the uplink resources actively allocated to the UE by the base station according to the second DCI, and sends a ULInformationTransfer to the base station through the uplink resources. The ULInformationTransfer includes an Identity response (Chinese: identity recognition response) to respond to the Identity request in an uplink manner.

[0134] Step 613: The base station sends an UPLINK NAS TRANSPORT (Chinese: uplink NAS transfer message) to the AMF: After receiving the ULInformationTransfer sent by the UE, the base station sends an UPLINK NAS TRANSPORT to the AMF, and the UPLINK NAS TRANSPORT includes an Identity response.
