Description

Technical Field

[0030] Based on the aforementioned description of the wireless communication system, such as Figure 1b As shown, this application also provides a communication switching system, which includes a first terminal, a second terminal, a first mobile access point, a second mobile access point, a first base station system, a second base station system, a first core network, and a second core network. The functions of the first core network include, but are not limited to, the AMF corresponding to the terminal, i.e., AMF for UE. The functions of the second core network include, but are not limited to, the AMF corresponding to the mobile access point (such as the first mobile access point), i.e., AMF for VMR.

[0031] Based on this, the technical solutions provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0032] like Figure 2 The diagram shown illustrates a flow chart of a mobility update method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0033] S210, when the terminal is camped on the first mobile access point, it performs a first mobility update operation and cancels a second mobility update operation.

[0034] The first mobile access point can be a vehicle (such as a high-speed rail or bus) or a mobile transfer device installed in the vehicle, and the terminal can be a user terminal, camera device, ticket vending machine, etc. located in the vehicle.

[0035] Based on this, after the terminal camps on the first mobile access point, considering that the terminal moves along with the first mobile access point, that is, the changes in the terminal's registration area or radio area are consistent with those of the first mobile access point, in order to avoid frequent mobility update operations, the terminal can perform a first mobility update operation when camping on the first mobile access point, and cancel the second mobility update operation that occurs after the first mobility update operation. This can effectively avoid the problem of high terminal power consumption caused by frequent mobility update operations when the terminal moves with the first mobile access point.

[0036] Meanwhile, if a large number of terminals move together with the first mobile access point, this application can also avoid signaling storms caused by frequent mobile update operations due to a large number of terminals moving out of the registration area or radio area during the movement process by canceling the second mobility update operation through the terminal, thereby ensuring wireless communication performance.

[0037] Of course, when the terminal moves with the first mobile access point, the terminal can access the first base station system through the first mobile access point, communicate with other terminals through the first mobile access point (understood as a relay), or communicate with other terminals without using the first mobile access point; no restrictions are imposed here.

[0038] In addition, when the terminal is stationed at the first mobile access point, it can move arbitrarily, such as from an idle state to the first mobile access point, or from an inactive state to the first mobile access point, without any restrictions.

[0039] In this embodiment, the terminal cancels other mobility update operations that occur after the first mobility update operation by performing a first mobility update operation after camping on the first mobile access point. This allows the terminal to reasonably control the number of mobility update operations when it moves out of the registration area or radio area, thereby reducing terminal power consumption, avoiding signaling storms, and ensuring wireless communication performance.

[0040] like Figure 3 The diagram shown is a flowchart illustrating a mobility update method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0041] S310, when the terminal is camped on the first mobile access point, it performs a first mobility update operation and cancels a second mobility update operation, or sends information to the core network side and cancels the first mobility update operation;

[0042] Wherein, the first mobile access point resides in the first base station system, and the second mobility update operation is a mobility update operation that occurs after the first mobility update operation.

[0043] It is understood that, in addition to referring to the relevant description in method embodiment 200, as a possible implementation method, whether the terminal cancels the second mobility update operation can be achieved by protocol agreement, higher layer configuration, network side configuration, etc.

[0044] For example, after the terminal camps on the first mobile access point, the first mobile access point can send a first indication message to the terminal, so that the terminal can cancel the second mobility update operation or cancel the first mobility update operation based on the first indication message.

[0045] The first indication information can be either explicit or implicit. For example, in the case of implicit indication, if the first indication information indicates to the terminal that the first mobile access point is a mobile access point, the terminal can determine that the second mobility update operation needs to be cancelled based on the first indication information. It is understood that since the terminal can move arbitrarily, when the terminal switches from the first mobile access point to the second mobile access point, the terminal is unaware whether the second mobile access point is a mobile access point.

[0046] Alternatively, the first indication information may include 1 bit of information used to indicate whether the terminal has cancelled the second mobility update operation.

[0047] In addition, when the terminal performs the first mobility update operation, it can obtain a first identifier from the first mobile access point, and then perform the step of performing the first mobility update operation based on the first identifier, or perform the step of sending information to the core network side based on the first identifier.

[0048] The first identifier may include at least one of Tracking Area Identity (TAI), Tracking Area Code (IMEI Type Allocation Code (TAC), Routing Area Identity (RAI), and Routing Area Code (RAC).

[0049] It should be noted that the first indication information and the first identifier can be sent to the terminal simultaneously by the first mobile access point. For example, the first mobile access point can send the first indication information and the first identifier to the terminal through a single message, or it can send the first indication information and the first identifier to the terminal through different messages. This embodiment does not impose any restrictions here.

[0050] In addition, both the first indication information and the identifier can be transmitted through system messages, broadcasts, multicasts, Radio Resource Control (RRC) messages, etc., without any restrictions.

[0051] Furthermore, when the terminal performs the first mobility update operation, the first mobility update operation may include at least one of the following (11)-(12).

[0052] (11) Registration operation.

[0053] (12) Radio Area Update operation.

[0054] Furthermore, when the terminal sends information to the core network side, the information may include at least one of the following (13)-(16).

[0055] (13) Registration information.

[0056] (14) Service Request information.

[0057] (15) Message Data Unit Session (PDU Session) information.

[0058] (16) Non-access stratum (NAS) information.

[0059] S320, when the terminal is camped on a second mobile access point or a second base station system, the terminal performs the second mobility update operation or performs the first mobility update operation.

[0060] Optionally, the second mobility update operation includes at least one of the following (21)-(22).

[0061] (21) Registration process.

[0062] (22) Wireless zone update operation.

[0063] Optionally, before performing the second mobility update operation, the terminal may first obtain the second mobility update operation from the second base station system or the second mobile access point, and perform the second mobility update operation based on the second identifier, or perform the first mobility update operation.

[0064] Similar to the first identifier, the second identifier may also include at least one of the following: tracking area identifier, tracking area code, routing area identifier, and routing area code.

[0065] Of course, please combine again Figure 1b During the mobility update process, assuming the terminal is stationed at the first mobile access point, the terminal can send relevant terminal information to the network side through the first mobile access point, wherein the relevant terminal information is used for at least one of the following (31)-(33).

[0066] (31) Associate the terminal with the first mobile access point.

[0067] The process of "associating the terminal with the first mobile access point" can be that the terminal sends relevant information to the network side to instruct (or request) the network side to associate the terminal with the first mobile access point, or the network side, after receiving the relevant information from the terminal, associates the terminal with the first mobile access point according to its own communication needs. This allows the network side to realize signaling transmission and terminal location determination between the two based on the association relationship.

[0068] It is understood that, assuming the terminal is a terminal that moves with the first mobile access point or the terminal is connected to the first mobile access point, when the network side needs the location information of the terminal or needs to perform signaling interaction with the terminal, it can obtain the location information of the terminal or perform signaling interaction with the terminal by obtaining the location information or signaling transmission information of the first mobile access point associated with the terminal. This can reduce signaling overhead and improve the efficiency of the communication process.

[0069] (32) Send first information to the terminal based on the relevant information of the first mobile access point.

[0070] The first information may be information requested by the terminal from the network side (such as the first base station system, the first core network function, the second core network function, etc.), or it may be information that the network side needs to send to the terminal. This application does not limit the type or content of the first information. For example, the first information may be user plane signaling, control plane signaling, etc. Accordingly, the first information is received and sent through the signaling plane or data plane.

[0071] In other words, in this application, the terminal reports its relevant information, enabling the network side to perform signaling interaction with the terminal based on the relevant information of the first mobile access point. This ensures signaling transmission between the network side and the terminal while reducing signaling overhead.

[0072] (33) Determine the location of the terminal based on the relevant information of the first mobile access point.

[0073] The terminal may request the network side to determine the terminal's location based on the relevant information of the first mobile access point after receiving the terminal's relevant information. Alternatively, when the network side needs to determine the terminal's location according to actual communication requirements, it may determine the terminal's location based on the terminal's relevant information and the relevant information of the first mobile access point. In other words, the terminal's relevant information is used by the network side to determine the terminal's location.

[0074] Furthermore, as a possible implementation, the relevant information of the terminal may include at least one of the following (41)-(43).

[0075] (41) The attribute information of the terminal; wherein, the attribute information of the terminal may include the terminal's identification information, the terminal's address (such as physical address or logical address, etc.), the terminal's connection identifier, the terminal's type information, etc., without limitation.

[0076] (42) The connection information between the terminal and the first mobile access point, such as whether the terminal and the first mobile access point are connected via Uu port or PC5 port, is not limited here.

[0077] (43) Network-side information, which serves the terminal. The network-side information includes information about the first base station system, information about the first core network function, information about the second core network function, etc.

[0078] Accordingly, the relevant information of the first mobile access point may include at least: the attribute information of the first mobile access point. The attribute information of the first mobile access point may include the type of the first mobile access point, the identification information of the first mobile access point, the address information of the first node, etc.

[0079] Corresponding to the terminal side, the first mobile access point can also report the relevant information of the terminal to the network side, or, after obtaining the relevant information of the terminal, the first base station system on the network side can also report the relevant information of the terminal and the relevant information of the first mobile access point to the core network function (such as the first core network function, the second core network function), so that the first base station system and / or the core network function can perform at least one of the aforementioned (31)-(33).

[0080] Of course, as one implementation method, in addition to the aforementioned information reporting, the relevant information of the terminal and the relevant information of the first mobile access point can also be configured in the first base station system and the core network function through protocol agreement, high-level configuration or network-side configuration, so as to realize signaling interaction with the terminal and determination of the terminal location based on the relevant information of the first mobile access point, without any restrictions.

[0081] In other words, the network side can realize signaling interaction with the terminal and determine the terminal's location based on the relevant information of the first mobile access point associated with the terminal. This avoids the problem in related technologies that require obtaining the terminal's communication-related information to realize signaling interaction with the terminal, reduces signaling overhead, and ensures the reliability of wireless communication.

[0082] In addition, if the first mobile access point switches from the first base station system to the second base station system, the first base station system can also send the relevant information of the terminal and the relevant information of the first mobile access point to the second base station system through the core network function, thereby ensuring that the core network function and the second base station system can realize signaling interaction with the terminal through the first mobile access point, and ensuring the continuity of the communication process.

[0083] like Figure 4 The diagram shown illustrates a flow chart of a mobility update method 400 provided in an exemplary embodiment of this application. This method can be, but is not limited to, executed by a first mobile access point, specifically by hardware and / or software installed in the first mobile access point. In this embodiment, the method 400 may include at least the following steps.

[0084] S410, the first mobile access point sends a first indication message, wherein the first indication message is used by the terminal to cancel the second mobility update operation or cancel the first mobility update operation based on the first indication message.

[0085] Wherein, the first mobile access point is camped on the first base station system, the first mobility update operation is a mobility update operation performed when the terminal is camped on the first mobile access point, and the second mobility update operation is a mobility update operation that occurs after the first mobility update operation.

[0086] Optionally, the first mobile access point sends the first indication information via at least one of the following: system message, broadcast, or Radio Resource Control (RRC) message.

[0087] Optionally, the method further includes: the first mobile access point sending a first identifier, wherein the first identifier is obtained by the first mobile access point from the first base station system; wherein the first identifier is used by the terminal to perform the first mobility update operation based on the first identifier, or to perform the step of sending information to the core network side based on the first identifier.
