Description

Information processing method, device and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on June 26, 2023, with application number 202310756999.1 and application name “A Method, Device and Equipment for Information Processing,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

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

[0003] Future 6th generation (6 th The 6G network adopts a decentralized hierarchical network with centralized and distributed collaboration. The 6G network is organized in a centralized and distributed collaborative and distributed autonomous manner. On the one hand, it extends more network functions to the edge of the network. On the other hand, it centralizes global core functions and supports more complex services through cloud-network integration and distributed collaboration.

[0004] In a distributed network scenario, each distributed node has a limited service area, managed by the centralized network node to which it belongs. For a user traveling at high or ultra-high speeds, choosing a centralized node for service may result in long signaling delays. Choosing a distributed network node with a smaller service area may result in frequent handoffs.

[0005] Specifically, related solutions (such as the registration process, deregistration process, access network release process, service request process, and data warehouse-based cross-domain mobility management process) retain the processing of user equipment (UE) context information in distributed network scenarios within the local network. This results in frequent mobile update and registration processes for UEs with high or ultra-high mobility, resulting in a poor service experience.

[0006] As mentioned above, in related solutions, UE context information is retained locally: within the distributed network node providing the service. This solution may result in high signaling overhead and poor service experience for high-speed or ultra-high-speed mobile UEs. If all neighboring nodes, centralized nodes, and / or non-neighboring nodes also store context information, network resources will be wasted.

[0007] Based on the above, the processing solutions for terminal context information in related technologies have problems such as high signaling overhead and waste of resources.

[0358] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0359] Regarding the 6G distributed network architecture vision:

[0360] A key trend in the development of 6G networks is the shift towards centralized and distributed network architectures. The original design of 5G and previous generations of network architectures was based on centralized control, meaning that core network functions were centrally deployed in core network rooms based on demand. As networks evolve, driven by both business scenarios and technological advancements, the architectural design of 6G networks needs to consider a distributed architecture, with control gradually evolving towards a distributed approach. With the distributed development of intelligence and cloud computing, new connections and networks will also require distributed deployment.

[0361] As shown in Figure 2, 6G will address diverse scenarios and network requirements in the air, space, land, and sea. A centralized network architecture cannot uniformly meet all scenarios. To address this challenge, the 6G network architecture needs to move beyond centralized control and gradually evolve toward a distributed architecture. This will extend more network functions (such as authentication) to the network edge and establish distributed, homogeneous micro-cloud units with varying levels of functionality. Each micro-cloud unit is self-contained and has complete control and data forwarding capabilities. Multiple micro-cloud units can form autonomous micro-networks based on business needs, providing targeted network services based on specific business scenarios, user scale, geographic environment, and other requirements. These micro-cloud units, also known as distributed network nodes, represent a customized or fully functional core network. These distributed network nodes are managed and controlled by a centralized network node.

[0362] Based on the foregoing, embodiments of the present disclosure provide an information processing method, apparatus, and device to address the high signaling overhead and resource waste associated with terminal context information processing solutions in related technologies. The method, apparatus, and device are based on the same patent application concept. Since the principles underlying the problems solved by the method, apparatus, and device are similar, their implementations can be referenced in conjunction with each other, and any repetitions will not be repeated.

[0363] The information processing method provided in the embodiment of the present disclosure is applied to a first network node, as shown in FIG3 , and includes:

The second network node includes: a centralized node, a cluster head node, or a target distributed network node. This method can store context information based on the UE mobility type, thereby avoiding frequent mobility updates caused by directly storing the context information in the distributed network node providing the service, thereby reducing signaling overhead.

[0378] Furthermore, the information processing method further includes: obtaining terminal context information from the second network node during the access network release process; and / or updating the terminal context information to the second network node when the access network is released.

[0436] In a distributed network scenario, (the first network node) determines a processing method for UE context information based on the UE mobility type (corresponding to the above-mentioned processing method for determining the terminal context information based on the current mobility type of the terminal):

[0437] 1) If the UE's mobility is no mobility or low mobility (corresponding to the mobility type of the above-mentioned terminal being the first type with a moving speed lower than the first threshold); for the UE registered with the network, the UE context and state information are stored in the currently serving network node (corresponding to the above-mentioned processing method including: storing the terminal context information in the distributed network node currently serving the terminal), and the Tracking Area Identity (TAI) list is determined by the distributed network node (it can also be understood that the Access and Mobility Management Function (AMF) included in the distributed node performs the aforementioned storage operation);

[0438] 2) If the UE's mobility is high speed or ultra-high speed (corresponding to the above-mentioned terminal's mobility type being the second type with a mobility speed greater than or equal to the first threshold); for the UE registered with the network, processing and data separation (i.e., decoupling of data and function) is adopted, and the data is stored in the centralized node and / or cluster head (through the concept of cluster division) and / or a distributed network node (which may be specified according to a compromise between the frequency of tracking area updates and paging resources or the service range, processing capability, connection capability with other distributed network nodes, etc.) and / or related distributed network nodes (related to the policy) (corresponding to the above-mentioned processing method including: storing the terminal context information in the second network node, the second network node is the target network node, and the second network node includes: a centralized node, a cluster head node, or a target distributed network node); wherein the (currently providing) service distributed network node has only processing capability, and the TAI list can be determined by the centralized node and / or cluster head (through the concept of cluster division) and / or a distributed network node (it can also be understood that the AMF contained in the distributed node or the centralized node performs the aforementioned storage operation). In this way, when moving to a new network node within the range of the TAI list, there is no need to re-register, and the mobility and periodic update registration process can be performed based on the TAI list (that is, there is no need to move and register frequently).

[0439] Among them: 1) The determination of the UE mobility type can be performed based on at least one of the following information: UE subscription information, UE mobility statistics, network local policy, UE auxiliary information, etc. (corresponding to the above-mentioned determination of the terminal's current mobility type based on the first information; wherein the first information includes at least one of the following: terminal subscription information; terminal mobility statistics; network local policy; terminal auxiliary information; terminal movement speed; terminal historical movement trajectory information). The determination of the UE mobility type can be determined by the base station and sent to the first network node, or can be determined by the first network node itself, which is not limited here.

[0440] 2) The data is stored in the access mobility management function (i.e., AMF) of the centralized node and / or cluster head and / or distributed network node (which may be specified based on a compromise between the frequency of tracking area updates and paging resources, or based on service scope, processing capabilities, etc.), or in a data warehouse (which can be understood as a place specifically for storing data) of the centralized node and / or cluster head and / or distributed network node. The corresponding terminal context information is stored in the first location of the distributed network node currently serving the terminal or the first location of the second network node; wherein the first location includes: the location corresponding to the access mobility management function or the location corresponding to the data warehouse.

[0441] The following is a specific example of this solution, in which the first position takes the position corresponding to the access and mobility management function AMF as an example.

[0442] Example 1, a method for selecting cluster heads or distributed network nodes;

[0443] In actual deployment, the centralized node may not work well. For example, if the service range of the centralized node is too large, it is necessary to divide the clusters based on demand to select the cluster head and the centralized node, or to use some method to select a distributed network node representative and the centralized node as the representative for storing UE context information. In this case, the second network node for storing the terminal context information may be determined by a compromise between the tracking area update frequency and the paging resource (which can be understood as the corresponding information obtained by considering the balance between the two), the service range of the distributed network node, the processing capability of the distributed network node, the hardware resources of the distributed network node, etc., or a combination thereof (corresponding to the above-mentioned determination of the second network node for storing the terminal context information based on the second information; wherein the second information includes at least one of the following: tracking area update frequency and paging resource information; distributed network node service range information; distributed network node processing capability information; distributed network node hardware resource information).

[0444] In a scenario where a cluster is represented or represented by a distributed network node, the information represented by the cluster head or distributed network node can be provided to other distributed network nodes within the range through configuration or broadcast messages (the cluster head and / or distributed network node and / or centralized node sends broadcast messages) (the information corresponding to the above-mentioned cluster head or target distributed network node is obtained through configuration or broadcast messages).

[0445] The following examples are based on the following assumptions:

[0446] (1) The data is stored in an access mobility management function of a centralized node and / or cluster head and / or distributed network node (specified according to a trade-off between tracking area update frequency and paging resources or service scope, processing capability, etc.), or in a data warehouse (a dedicated place for storing data) of the centralized node and / or cluster head and / or distributed network node. The terminal context information is stored in a first location of the distributed network node currently serving the terminal or a first location of the second network node; wherein the first location includes: a location corresponding to the access mobility management function or a location corresponding to the data warehouse.

[0447] (2) The UE mobility type may be determined based on at least one of the following information: UE subscription information, UE mobility statistics, network local policy, UE auxiliary information, etc. (corresponding to the above-mentioned determination of the current mobility type of the terminal based on the first information; wherein the first information includes at least one of the following: terminal subscription information; terminal mobility statistics; network local policy; terminal auxiliary information; terminal movement speed; terminal historical movement trajectory information).

[0448] (3) The Radio Access Network (RAN, which can be understood as a base station) selects the AMF. Specifically, the AMF may be selected based on at least one of the RAN local configuration, and / or the AMF load and priority, and / or valid information carried by the UE, but is not limited thereto.

[0449] This solution uses the above method to save UE context information, which saves more network resources compared to using all neighbor nodes and / or centralized nodes and / or non-neighbor nodes to save UE context information.

[0450] The following example takes the second network node as a centralized node; the signaling process taking the cluster head or distributed network node representative (corresponding to the above-mentioned target distributed network node) as an example is similar and will not be described in detail below.

[0451] Example 2: The mobility is a high-speed or ultra-high-speed mobility scenario.

[0452] In example 2.1, the centralized node participates in completing the UE registration process.

[0453] As shown in Figures 5 and 6, in steps 1 and 2, after the RAN receives the registration request from the UE, it performs operations including selecting a source access mobility management function and forwarding the registration request message to the source access mobility management function. Then, after receiving the registration request, the source access mobility management function may execute other registration procedures (for details, please refer to the existing procedures and will not be repeated here).

[0454] Before the source access mobility management function sends a registration acceptance message to the UE (see steps 3a and 3b of FIG5 ) or after (see steps 4a and 4b of FIG6 ), the UE mobility type is determined (corresponding to the above-mentioned determination of the current mobility type of the terminal based on the first information before sending a registration acceptance message to the terminal during the registration process). If it is determined to be no mobility or low mobility, steps 3a and 3b or steps 4a and 4b are omitted. If it is determined to be high-speed mobility or ultra-high-speed mobility, the (source) access mobility management function carries the UE context (including status information) by sending a UE context establishment request message to the access mobility management function of the centralized node (i.e., the target access mobility management function) (corresponding to the above-mentioned sending of terminal context information to the second network node before or after sending a registration acceptance message to the terminal during the registration process when the terminal's mobility type is the second type). After receiving the (UE context establishment) request, the access mobility management function of the centralized node saves the UE context information, allocates information such as a periodic registration update timer and a registration area to the UE, and carries the information to the access mobility management function of the current service through a UE context establishment response message (corresponding to the above-mentioned receiving information about the periodic registration update timer and / or registration area allocated to the terminal by the second network node when the mobility type of the terminal is the second type). At this time, the access mobility management function of the current service is only responsible for the processing logic of the UE.

[0455] In this example, step 4 in Figure 5 can be executed: after the access mobility management function of the current service (i.e., the source access mobility management function) receives the (UE context establishment) response message, it sends a registration acceptance message to the UE; or, step 3 in Figure 6 can be executed: before the (source) access mobility management function sends a UE context establishment request message to the access mobility management function of the centralized node, the source access mobility management function sends a registration acceptance message to the UE; this is not limited here.

[0456] Among them: (1) UE can perform mobility and periodic update registration process based on TAI list.

[0457] Step 5: Execute the remaining registration processes. For details, please refer to the existing processes and will not be repeated here.

[0458] For example, in 2.2, the registration scenario;

[0459] As shown in Figures 7, 8 and 9, after the access mobility management function of the current service (i.e., the source access mobility management function) receives the deregistration request of the UE, step 2 is performed, that is, a UE context acquisition request (corresponding to the above-mentioned first acquisition request) is sent to the access mobility management function of the centralized node (i.e., the target access mobility management function) and a UE context acquisition response (corresponding to the above-mentioned first acquisition response) is received, thereby obtaining the context information of the UE (corresponding to the above-mentioned acquisition of terminal context information from the second network node during the deregistration process). The specific context information obtained may include registration information, session information, and other context information, but is not limited to this.

[0460] Step 3: For other deregistration processes, please refer to the existing processes for details and will not be repeated here.

[0461] Subsequently, before the source access mobility management function sends a deregistration accept message to the UE (see steps 4a and 4b in Figure 7) or after (see steps 5a and 5b in Figure 8) or after all deregistration processes are completed (see steps 6a and 6b in Figure 9), a UE context release request (i.e., a UE context deregistration request) is sent to the access mobility management function of the centralized node (i.e., the target access mobility management function; corresponding to the above-mentioned second network node) to inform the centralized node that the UE has completed deregistration (corresponding to the above-mentioned sending of a notification information that the terminal deregistration is completed to the second network node before or after the deregistration accept message is sent to the terminal, or after the N2 signaling connection is released), and a corresponding response is received.

[0462] Among them, step 6 of FIG. 7 , step 6 of FIG. 8 , and step 5 of FIG. 9 are all for executing the remaining deregistration processes. For details, please refer to the existing processes and will not be repeated here.

[0463] Example 2.3, AN release;

[0464] As shown in Figure 10, after the AN release process is completed, the access mobility management function of the current service sends a UE context modification request (corresponding to the above-mentioned second acquisition request) to the access mobility management function of the centralized node to inform the centralized node that the status of the UE has changed from a connected state to an idle state, and receives a corresponding response (corresponding to the above-mentioned second acquisition response). For details, refer to steps 2a and 2b (corresponding to the above-mentioned updating of the terminal context information to the second network node when the access network is released).

[0465] Example 2.4, handover --- T (target) - access mobility management function to obtain UE context information;

[0466] In this handover scenario, the access mobility management function may be replaced, specifically Xn handover or N2 handover. In this example, by separating data from processing or obtaining UE context data from a centralized node, there is no need to frequently initiate the N2 handover process even across distributed network nodes. This is shown in Figure 11:

[0467] Step 0. The terminal, S (source)-RAN, and T-RAN collaborate to prepare for handover and execute handover.

[0468] Step 1.1: T-RAN sends an N2 path switching request to the S-Access and Mobility Management Function. This step corresponds to Xn switching.

[0469] In step 1.2, the S-RAN sends an N2 path switching request to the S-Access and Mobility Management Function; this step corresponds to N2 handover.

[0470] Step 2: The S-access and mobility management function selects the T-access mobility management function.

[0471] Step 3: The S-access mobility management function (i.e., access and mobility management function) sends a handover request to the T-access mobility management function, carrying the address information of the UE context information storage (corresponding to the storage address of the terminal context information sent to the target network node).

[0472] In steps 4 and 5, the T-access mobility management function obtains UE context information based on the address information stored in the UE context information in step 3 (corresponding to obtaining the terminal context information obtained from the source network node from the second network node based on the storage address of the terminal context information), including session information. The UE handover process is then completed (i.e., step 6, other handover processes, for details, refer to existing processes and are not further described here).

[0473] Specifically, the T-access mobility management function sends a UE context acquisition request to the access mobility management function of the centralized node and receives a corresponding response (corresponding to the above-mentioned sending a third acquisition request to the second network node according to the storage address; receiving a third acquisition response fed back by the second network node, the third acquisition response carrying terminal context information).

[0474] In steps 7-8, after the UE handover is completed, the T-access mobility management function sends a UE context update request to update the UE context information, such as the access mobility management function of the current service, UE location information, session-related information, etc. This corresponds to the above-mentioned updating of the terminal context information to the second network node when the handover is completed.

[0475] Example 2.5, Handover - S-Access Mobility Management Function Obtains UE Context Information;

[0476] In this handover scenario, the access mobility management function may need to be replaced; specifically, it may involve Xn handover or N2 handover. In this example, by separating data from processing or obtaining UE context data from a centralized node, it is not necessary to frequently initiate N2 handover procedures even across distributed network nodes.

[0477] Unlike Example 2.4, in this example, the S-access mobility management function obtains UE context information from the access mobility management function of the centralized node and forwards it to the T-access mobility management function. As shown in Figure 12, this example includes the following steps:

[0478] Step 0. The terminal, S (source)-RAN, and T-RAN collaborate to prepare for handover and execute handover.

[0479] Step 1.1: T-RAN sends an N2 path switching request to the S-Access and Mobility Management Function. This step corresponds to Xn switching.

[0480] In step 1.2, the S-RAN sends an N2 path switching request to the S-Access and Mobility Management Function; this step corresponds to N2 handover.

[0481] Step 2: The S-access and mobility management function selects the T-access mobility management function.

[0482] In steps 3 and 4, the S-access mobility management function obtains UE context information based on the stored address information (corresponding to obtaining the terminal context information from the second network node according to the storage address of the terminal context information), including session information.

[0483] Specifically, the S-access mobility management function sends a UE context acquisition request to the access mobility management function of the centralized node and receives a corresponding response (corresponding to the above-mentioned sending a third acquisition request to the second network node according to the storage address; receiving a third acquisition response fed back by the second network node, the third acquisition response carrying terminal context information).

[0484] In step 5, the S-Access Mobility Management Function (i.e., the Access and Mobility Management Function) sends a handover request to the T-Access Mobility Management Function, carrying the acquired UE context information (corresponding to the aforementioned sending of the terminal context information to the target network node). For the T-Access Mobility Management Function, this is the terminal context information received from the source network node.

[0485] After that, the UE's handover process is completed (ie, step 6, other handover processes, for details, please refer to the existing processes, which will not be repeated here).

[0486] In steps 7-8, after the UE handover is completed, the T-access mobility management function sends a UE context update request to update the UE context information, such as the access mobility management function of the current service, UE location information, session-related information, etc. This corresponds to the above-mentioned updating of the terminal context information to the second network node when the handover is completed.

[0487] Example 2.6, business request scenario;

[0488] As shown in Figures 13 and 14, in steps 1-2, after receiving a service request sent by the UE, the access mobility management function of the current service (i.e., the source access mobility management function) obtains UE context information from the access mobility management function of the centralized node (i.e., the target access mobility management function) (corresponding to obtaining terminal context information from the second network node during the service request process described above). Specifically, the source access mobility management function sends a UE context acquisition request to the target access mobility management function and receives a corresponding response (corresponding to sending a fourth acquisition request to the second network node after receiving the service request sent by the terminal; and receiving a fourth acquisition response fed back by the second network node, wherein the fourth acquisition response carries the terminal context information).

[0489] Step 3: Execute other business request processes. For details, please refer to the existing processes and will not be repeated here.

[0490] In step 4 of FIG13 , the RAN sends an N2 request ACK (acknowledgement) to the access mobility management function of the current service (ie, the source access mobility management function).

[0491] In steps 5a-5b of Figure 13 and steps 4a-4b of Figure 14 : After receiving the N2 request ACK (acknowledgement) sent by the RAN or after the AN release process is completed, the access mobility management function of the current service may update the UE context information to the access mobility management function of the centralized node (corresponding to the updating of the terminal context information to the second network node during the service request process described above). Specifically, the source access mobility management function sends a UE context modification request to the target access mobility management function and receives a corresponding response (corresponding to the updating of the terminal context information to the second network node after receiving the N2 request response, or after receiving the terminal context release complete message, or after receiving the information update response message of the protocol data unit session).

[0492] As for the remaining business processes in step 6 of FIG13 , please refer to the existing processes for details and will not be described in detail here.

[0493] Example 3: A scenario where the UE mobility type changes;

[0494] The specific scenario of this example is: when the UE is in the registered state, it changes from high speed or ultra-high speed to low speed or no mobility, or changes from low speed or no mobility to high speed or ultra-high speed.

[0495] The details are shown in Figure 15:

[0496] Step 1. The RAN detects the speed of the UE. The RAN or the access mobility management function (providing) the service determines, based on the detected speed or in combination with the historical movement trajectory (corresponding to the above-mentioned first information including: terminal movement speed; and / or historical movement trajectory information of the terminal), whether the UE's mobility type has changed from high speed or ultra-high speed to low speed or no mobility, or from low speed or no mobility to high speed or ultra-high speed.

[0497] Step 2-3. The serving access mobility management function (which may correspond to the first network node) sends a UE mobility type update request to the access mobility management function of the centralized node (which may correspond to the second network node) to update the UE mobility type (corresponding to updating the terminal mobility type to the second network node in the case of the terminal mobility type update). After the update is successful, the access mobility management function of the centralized node returns a response message (i.e., a UE mobility type update response).

[0498] Step 4. If the configuration information of the UE needs to be updated, such as TAI information, a configuration update process is initiated (corresponding to the above-mentioned initiation of a configuration update process when the configuration update conditions of the terminal are met).

[0499] It is noted here that the relevant contents of the above first network node side solution and the second network node side solution can be referenced to each other, and the relevant contents in the above examples can also be referenced to each other, and the repeated parts will not be repeated.

[0500] As described above, the solution provided by the embodiment of the present disclosure relates to a processing method for determining UE context information based on UE mobility type in a distributed network scenario:

[0501] 1.1 If the UE's mobility is no mobility or low mobility, the UE context and state information are stored in the current serving network node, and the TAI list is determined by the distributed network node;

[0502] 1.2 If the UE's mobility is high-speed or ultra-high-speed, separation of processing and data (decoupling of data and functions) is adopted. The data is stored in the centralized node and / or cluster head and / or a representative of a distributed network node. The serving distributed network node only has processing capabilities, and the TAI list can be determined by the centralized node.

[0503] The determination of the UE mobility type can be based on at least one of the information such as UE subscription information, UE mobility statistics, network local policy, UE auxiliary information, etc.; the determination of the cluster head or a distributed network node representative can be determined based on one or more combinations of the frequency of tracking area updates and paging resources, the service range of the distributed network node, the processing capability of the distributed network node, the hardware resources of the distributed network node, etc.; the information of the cluster head or the distributed network node representative can be provided to other distributed network nodes within the range through configuration or broadcast messages (cluster head and / or distributed network node and / or centralized node sends broadcast messages).

[0504] 2.1 During the registration process, the UE mobility type needs to be determined before a registration acceptance message is sent to the UE (corresponding to the above-mentioned determination of the current mobility type of the terminal based on the first information before a registration acceptance message is sent to the terminal during the registration process):

[0505] 2.1.1 If it is high-speed mobility or ultra-high-speed mobility, the UE context, including status information, is sent to the centralized node for storage. At the same time, the centralized node allocates periodic registration update timer, registration area and other information to the UE (corresponding to the above-mentioned registration process, when the terminal's mobility type is the second type, before or after sending a registration acceptance message to the terminal, sending terminal context information to the second network node; receiving the periodic registration update timer and / or registration area information allocated by the second network node to the terminal).

[0506] 2.2 Add the access mobility management function of the current service to the deregistration process, and obtain the UE's context information from the access mobility management function of the centralized node and inform the UE that the deregistration has been completed (corresponding to the above-mentioned process of obtaining the terminal context information from the second network node and notifying the terminal that the deregistration has been completed during the deregistration process).

[0507] 2.3AN release process, first obtain UE context information from the centralized node; after AN release is completed, update the UE context information to the centralized node (corresponding to the above-mentioned process of obtaining terminal context information from the second network node during access network release; and / or, when the access network is released, updating the terminal context information to the second network node).

[0508] 2.4 Handover process, obtain terminal context from the centralized node;

[0509] 2.4.1 The T-access mobility management function obtains UE context information based on the address information of the UE context information storage obtained from the S-access mobility management function (corresponding to the above-mentioned acquisition of the terminal context information from the second network node according to the storage address of the terminal context information obtained from the source network node).

[0510] 2.4.2 The S-access mobility management function forwards the obtained UE context information to the T-access mobility management function (corresponding to the above-mentioned acquisition of the terminal context information from the second network node according to the storage address of the terminal context information; and sending the terminal context information to the target network node).

[0511] 2.4.3 After the handover in 2.4.1 or 2.4.2 is completed, the T-access mobility management function updates the UE context information to the centralized node (corresponding to the above-mentioned updating of the terminal context information to the second network node when the handover is completed).

[0512] 2.5 Service request process, it is necessary to obtain UE context information from the centralized node; thereafter, it is necessary to update the UE context information to the centralized node (corresponding to the above-mentioned process of obtaining terminal context information from the second network node and updating terminal context information to the second network node during the service request process).

[0513] 3. When the UE mobility type changes:

[0514] 3.1. RAN detects the UE's speed. The RAN or the service's access mobility management function determines the UE's mobility type based on the detected speed or in combination with historical movement trajectory.

[0515] 3.2. The access mobility management function of the service sends a UE mobility type update request to the access mobility management function of the centralized node (corresponding to the above-mentioned case where the mobility type of the terminal is updated, the terminal mobility type is updated to the second network node).

[0516] 3.3. If the configuration information of the UE needs to be updated, a configuration update process is initiated (corresponding to the above-mentioned initiation of a configuration update process when the configuration update conditions of the terminal are met).

[0517] In summary, this solution has the following advantages:

[0518] 1. Taking user mobility into consideration, the processing of context information is more reasonable, saving network resources.

[0519] 2. In high-speed or ultra-high-speed mobility scenarios, although the UE is served by different mobility management functions, there is no need for frequent mobility update procedures, which reduces signaling overhead.

[0520] 3. The data and processing separation method is more suitable for distributed network scenarios.

[0521] 4. The network node storing UE context information considers more factors such as the trade-off between tracking area update frequency and paging resources, reducing signaling overhead.

[0522] In summary, this solution can reasonably process UE context information in a distributed network scenario based on the mobility attributes of UE, reduce signaling overhead and improve service experience.

[0523] The embodiment of the present disclosure further provides an information processing device, which is a first network node, as shown in FIG16 , including a memory 161 , a transceiver 162 , and a processor 163 :

[0524] The memory 161 is used to store computer programs; the transceiver 162 is used to send and receive data under the control of the processor 163; the processor 163 is used to read the computer program in the memory 161 and perform the following operations:

[0525] Determine how to process the terminal context information based on the terminal's current mobility type;

[0526] Wherein, in the case where the mobility type of the terminal is the first type in which the mobility speed is lower than the first threshold, the processing method includes: storing the terminal context information in a distributed network node currently serving the terminal;

[0527] In the case where the terminal's mobility type is the second type with a moving speed higher than or equal to the first threshold, the processing method includes: storing the terminal context information in a second network node, where the second network node is a target network node, and the second network node includes: a centralized node, a cluster head node, or a target distributed network node.

[0528] The information processing device provided by the embodiment of the present disclosure determines a processing method for terminal context information based on the current mobility type of the terminal. Specifically, when the mobility type of the terminal is a first type with a mobility speed lower than a first threshold, the processing method includes: storing the terminal context information in a distributed network node currently serving the terminal; when the mobility type of the terminal is a second type with a mobility speed higher than or equal to the first threshold, the processing method includes: storing the terminal context information in a second network node, which is a target network node. The second network node includes: a centralized node, a cluster head node, or a target distributed network node. This device can store context information based on the UE mobility type, thereby avoiding frequent mobility updates caused by directly storing the context information in the distributed network node providing the service, thereby reducing signaling overhead. It can also avoid the waste of network resources caused by all neighboring nodes and / or centralized nodes and / or non-neighboring nodes storing the context information, thereby achieving the purpose of saving network resources. This device effectively solves the problems of high signaling overhead and resource waste in the processing solutions for terminal context information in related technologies.

[0529] Specifically, the transceiver 162 is configured to receive and send data under the control of the processor 163 .

[0530] In FIG16 , the bus architecture may include any number of interconnected buses and bridges, specifically various circuits linking together one or more processors represented by processor 163 and memory represented by memory 161. The bus architecture may also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 162 may be a plurality of components, i.e., a transmitter and a receiver, providing a unit for communicating with various other devices over a transmission medium, such as a wireless channel, a wired channel, an optical cable, or the like. The processor 163 is responsible for managing the bus architecture and general processing, and the memory 161 may store data used by the processor 163 when performing operations.

[0531] The processor 163 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0532] Furthermore, the operation also includes: determining the current mobility type of the terminal based on the first information; wherein the first information includes at least one of the following: terminal contract information; terminal mobility statistical information; network local policy; terminal auxiliary information; terminal movement speed; and terminal historical movement trajectory information.

[0533] The determining of the current mobility type of the terminal based on the first information includes: determining the current mobility type of the terminal based on the first information before sending a registration acceptance message to the terminal during the registration process; and storing the terminal context information in the second network node includes: using the transceiver to send the terminal context information to the second network node before or after sending a registration acceptance message to the terminal when the terminal's mobility type is the second type during the registration process.

[0534] Furthermore, the operation further includes: when the mobility type of the terminal is the second type, using the transceiver to receive information about a periodic registration update timer and / or a registration area allocated by the second network node to the terminal.

[0535] In the embodiment of the present disclosure, the operation further includes: during the deregistration process, obtaining terminal context information from the second network node and notifying the terminal that the deregistration is completed.
