[0042] The present application embodiment provides a switching method, such as Figure 1 As shown, applied to a first base station, the method may include:

[0043] S101. Receive a non-connectivity service switching request message sent by a second base station.

[0044] In an embodiment of the present application, the first base station is a destination base station to be switched, and the second base station is a source base station or a computing service node to which the terminal is currently connected.

[0046] In an embodiment of the present application, after the second base station receives the measurement report (Measurement Report, MR) reported by the terminal and makes a switching decision, when it determines that a connection switching needs to be performed, when the second base station provides both connection service and non-connection service, the second base station sends a first switching request message to the first base station, and the first switching request message includes a connection switching request message and a non-connection service switching request message; the first base station receives the first switching request message sent by the second base station.

[0047] In some embodiments, the terminal may be referred to as User Equipment (UE). The terminal may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), etc. The terminal may also be a smart phone, a tablet computer, a PDA, a Mobile Station (MS), a Mobile Terminal, etc. The terminal may communicate with one or more network devices via a Radio Access Network (RAN).

The terminal may also be a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future evolving network, etc., which is not limited in the implementation of this application.

[0048] In the embodiment of the present application, the non-connection service switching request carries the first information, and the first information includes at least one of the following: non-connection service type information, non-connection service resource requirement information, and non-connection service life cycle state information. The specific information can be selected according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0049] Optionally, the non-connectivity service type information may include perception service, computing service, AI service and other type information, which may be selected based on actual conditions, and the embodiments of the present application do not make any specific limitations.

[0050] Optionally, the non-connectivity service resource requirement information may include resources such as CPU, graphics processing unit (GPU), tensor processing unit (TPU), memory, hard disk and corresponding size requirement information. The specific one can be selected according to actual conditions, and the embodiments of the present application do not make specific limitations.

[0051] Optionally, the non-connection service life cycle status information may include periodic / non-periodic, period size, current execution start and end status and other information, which can be selected according to actual conditions and is not specifically limited in the embodiments of the present application.

[0052] In an embodiment of the present application, a connection is established between the first base station and the second base station based on XnAP (Layer n Access Protocol), and the second base station sends a first switching request message carrying a non-connection service switching request message to the second base station through the Xn interface (network interface) between the first base station and the second base station.

[0053] S102: Determine whether switching to a non-connection service is allowed.

[0054] It should be noted that the original handover admission switching admission judgment condition is enhanced on the base station side. Specifically, based on the resource information of the first base station and the first information, it is judged whether the non-connectivity service is allowed to be switched.

[0055] In an embodiment of the present application, whether the first information is satisfied is determined based on the resource information of the first base station. If the resource information of the first base station can satisfy the first information, switching of the non-connection service is allowed; if the resource information of the first base station cannot satisfy the first information, switching of the non-connection service is not allowed.

[0056] For scenarios where switching to non-connected services is not allowed, specifically: if the non-connected service lifecycle status information is executing, the source base station cannot complete the data transfer because it is in the calculation process, and thus switching to non-connected services is not allowed; if the resource information of the first base station cannot meet the resource requirements of the non-connected service, then it indicates that the computing power resources of the first base station are insufficient, and thus switching to non-connected services is not allowed.

[0057] S103: When it is determined that switching of the non-connectivity service is not allowed, send a non-connectivity service non-switching message to the second base station.

[0058] In an embodiment of the present application, when it is determined that switching to a non-connectivity service is not allowed, a first switching confirmation message is sent to the second base station; the first switching confirmation message includes a connectivity switching message and a non-connectivity service non-switching message.

[0059] Furthermore, when it is determined that switching to non-connectivity service is allowed, indicating that the non-connectivity service is not being executed and the computing resources of the first base station are sufficient, a second switching confirmation message is sent to the second base station; wherein the second switching confirmation message includes a connection switching message and a non-connectivity service switching message.

[0060] In an embodiment of the present application, the first base station sends a first switching confirmation message or a second switching confirmation message to the second base station through a network interface between the first base station and the second base station.

[0061] It should be noted that the network interface between the first base station and the second base station may be an Xn interface.

[0062] S104, receiving non-connection service identification information sent by the second base station; the non-connection service identification information is used to implement the identification and forwarding processing process for the non-connection service data after the terminal switches to access the first base station.

[0063] In the embodiment of the present application, the non-connection service identification information includes: terminal identification and non-connection service sequence number information.

[0064] In an embodiment of the present application, the non-connection service identification information is carried in a sequence number identification transmission (SNStatusTrans) message.

[0065] In an embodiment of the present application, the second base station sends an SNStatus Trans message to the first base station through a network interface between the first base station and the second base station.

[0066] It should be noted that after receiving the non-connection service identification information sent by the second base station, the connection switching process of the terminal from the second base station to the first base station is executed, including RRC reconfiguration, data transmission, random access channel (Random Access Channel, RACH) and other processes.

[0067] Furthermore, after the terminal switches from the second base station to the first base station, the first base station receives the first data sent by the terminal; when it is determined that the first data is non-connection service data based on the non-connection service identification information, the first data is forwarded to the second base station for processing; first result data corresponding to the first data returned by the second base station is received; and the first result data is forwarded to the terminal.

[0068] It should be noted that for the first base station, related functions of non-connection services are added, including non-connection service execution status maintenance (including task start time, whether the task is completed, task termination time, etc.), non-connection service data identification, cross-station non-connection service data forwarding and other functions.

[0069] It should be noted that the enhanced non-connectivity service-related data transmission between base stations is used for the interaction and collaborative processing of non-connectivity service data.

[0070] It can be understood that, in terms of interface messages, the present application first enhances the control plane signaling compared to the original Xn interface: specifically, the control plane interface adds new non-connection-related control instruction transmission, including: switching request (S101): new information about non-connection services, including the terminal's non-connection service type (perception, computing, AI, etc.), service resource requirements (CPU, GPU, TPU, memory, hard disk and other resources and corresponding size requirements), service life cycle status (periodic / non-periodic, cycle size, current execution start and end status, etc.). Switch confirmation (S102): Add an indication of whether to accept the switching of non-connection services. Status transmission (S103): Add a new non-connection service identifier (terminal identifier, non-connection service serial number, etc.) for the first base station to identify and forward non-connection service data. Secondly, enhance data transmission: specifically, enhance non-connection-related data transmission between base stations for interaction and collaborative processing of non-connection-related data.

[0071] It can be understood that the newly added non-connection service-related control instruction transmission enables the second base station to send a non-connection service switching request message to the first base station, the first base station executes a judgment on whether the switching of the non-connection service is allowed, and the second base station sends the non-connection service identification information to the first base station; when the first base station determines that the switching process of the non-connection service is not allowed, the switching of the non-connection service is not executed during the base station switching access process, and in the non-connection service data processing process after the base station switching, the first base station performs the identification and forwarding processing operations of the non-connection service data based on the non-connection service identification information sent by the second base station, and the first base station and the second base station collaborate in processing the non-connection service data, which can ensure the continuous execution of the non-connection service when the base station switches.

[0072] Based on the above embodiment, the present application embodiment further proposes a switching method, which is applied to the second base station, such as Figure 2 As shown, the method may include:

[0073] S201. Send a non-connectivity service switching request message to a first base station.

[0075] S202: Receive a non-connectivity service non-switching message sent by the first base station.

[0076] In an embodiment of the present application, the second base station sends a first switching request message to the first base station, and the first switching request message includes a connection switching request message and a non-connection service switching request message; thereafter, the second base station receives a first switching confirmation message sent by the first base station; the first switching confirmation message includes a connection switching message and a non-connection service non-switching message.

[0077] S203, sending non-connection service identification information to the first base station; the non-connection service identification information is used to implement the identification and forwarding processing process for the non-connection service data after the terminal switches to access the first base station.

[0078] In the embodiment of the present application, the non-connection service identification information includes at least one of the following: a terminal identification and non-connection service sequence number information.

[0079] It should be noted that the non-connectivity service switching request message, the non-connectivity service non-switching message and the non-connectivity service identification information are transmitted through the network interface between the first base station and the second base station.

[0080] In an embodiment of the present application, after the terminal switches to the first base station for connection, when the terminal sends the first data to the first base station, the second base station receives the first data sent by the first base station; the second base station processes the first data to obtain first result data; thereafter, the second base station returns the first result data to the first base station.

[0081] It should be noted that S201-S203 are methods on the opposite side of S101-S104. For the specific description of S201-S203, reference can be made to the description of S101-S104, which will not be repeated here.

[0082] Based on the above embodiments, the present application proposes a message transmission method for inter-base station service collaboration, such as Figure 3 As shown, the method may include:

[0083] 1. The initial access process of the terminal to the core network.

[0084] It should be noted that the XnAP: connection establishment process is executed between the source base station and the target base station.

[0085] 2. The terminal reports the measurement report to the source base station.

[0086] 3. The source base station executes the handover decision.

[0087] 4. When it is detected that a base station connection switching needs to be performed, a connection switching request and a non-connection service switching request are sent to the target base station.

[0088] It should be noted that the connectionless service switching request carries the connectionless service type information, the connectionless service resource requirement information, and the connectionless service life cycle state information.

[0089] 5. The target base station determines whether to allow switching to the non-connection service based on the non-connection service switching request.

[0090] 6. The target base station sends a first switching confirmation message to the source base station.

[0091] It should be noted that the first switching confirmation message includes connection switching and non-connection service non-switching.

[0092] 7. The source base station sends a connection switching instruction to the terminal.

[0093] 8. The source base station sends an SNStatus Trans message carrying non-connection service identification information to the target base station.

[0095] 9. Execute the switching process.

[0096] 10. A handover state based on the Next Generation Access Protocol (NGAP) protocol is executed between the target base station and the core network.

[0097] 11. The target base station sends a terminal connection context release message to the source base station.

[0099] 12. The terminal transmits non-connection service data to the target base station.

[0100] 13. The target base station forwards the non-connection service data to the source base station for processing.

[0101] 14. The source base station sends the first result data to the target base station.

[0102] 15. The target base station sends first result data to the terminal.

[0103] 12-15 Completed the post-switching non-connection service process.

[0104] Based on the above embodiments, taking the network providing computing services as an example, an embodiment is proposed, in which the computing service control of the base station is separated from the computing data transmission function, see Figure 4, where the main base station of the source computing service node and the main base station of the target computing service node are both in 5GC, the main base station is responsible for computing service control, the slave base station is responsible for providing computing power, the main base station of the source computing service node and the main base station of the target computing service node are connected through an Xn interface, and the slave base station of the source computing service node and the slave base station of the target computing service node are connected through an Xn interface. Control plane signaling is implemented between the main base station of the source computing service node and the main base station of the target computing service node to achieve base station connection switching after the terminal moves. The terminal connects to the slave base station of the target computing service node for service. Since the slave base station of the target computing service node cannot meet the computing requirements, the terminal transmits the computing data to the slave base station of the source computing service node through the slave base station of the target computing service node to provide computing power.

[0105] The protocol stack diagram between nodes is as follows: Figure 5 As shown, computing service messages are added to the air interface messages of the Radio Resource Control (RRC) layer of the terminal and the base station-slave station, including: authentication, computing request, dedicated bearer, quality of service (QoS), mobility guarantee, idle state enhancement, etc. Computing control messages are added to the Xn messages of the Xn-AP layer of the base station-slave station and the base station-master station 1, including: available resource reporting, node selection, task allocation, context, state management, etc. Computing control messages are added to the Xn-C messages of the Xn-AP layer of the base station-master station 1 and the base station-master station 2, which are used to inform the slave station to continue processing computing data after the master station is switched, including: synchronization of available resource information, interaction of context and necessary information, state management, etc. Control management message enhancements are added to the N2 messages of the NG-AP layer of the base station-master station 2 and the authentication management function (AMF), which are used to continue billing and other management of the master station 1 after the master station is switched, including: access authentication, billing, etc.

[0106] Based on the above embodiments, taking the network providing computing services as an example, an embodiment is proposed, in which the computing service control and computing data transmission functions of the base station are combined, see Figure 6 , where both the source base station and the target base station are in 5GC, the source base station provides computing services, the target base station provides connection services, the source base station and the target base station are connected via an Xn interface, the source base station and the target base station interact with each other via control plane signaling to implement base station connection switching, after the terminal moves from the source base station to the target base station, it performs connection services with the target base station, after which the terminal transmits the calculation data to the source base station through the target base station for calculation, and transmits the calculation result data to the terminal through the target base station.
