[0002] With the development of network and the improvement of traffic convenience, people can connect to the network in different places and enjoy the convenience brought by the network.

[0003] In the process of network connection and communication, the same terminal device can be in the home place and connected to the home network, or in the roaming place and connected to the roaming network. For terminal devices in different home places, the routing policy corresponding to the home place will be executed.

[0065] Please see Figure 3 , Figure 3 A flowchart illustrating a method for implementing a terminal dynamic policy according to an embodiment of this disclosure is shown schematically. Figure 3 As shown, the method for implementing dynamic terminal policies may include:

[0066] S320. It is detected that the terminal accesses the roaming network, and the routing policy executed by the terminal is inconsistent with the roaming policy. The roaming network and the roaming policy have a corresponding relationship.

[0067] S330. Based on the roaming policy and the routing policy executed by the terminal, a new routing policy is obtained.

[0068] S340. The new routing policy is sent to the terminal, and the terminal executes the new routing policy.

[0069] Implementation Figure 2 The terminal dynamic policy method shown involves obtaining a new routing policy based on the roaming policy and the terminal's routing policy when the terminal accesses a roaming network and the routing policy executed by the terminal is inconsistent with the roaming location policy. The new routing policy is then sent to the terminal for execution. Implementing embodiments of this disclosure, on the one hand, by modifying the terminal's routing policy accordingly when accessing a roaming network and encountering routing policy conflicts to comply with the specific policy requirements of the roaming location, network problems can be avoided or the problem incidence rate reduced. On the other hand, it eliminates the need for manual operation, directly obtaining a new routing policy based on the roaming location policy and the terminal's routing policy, thus improving the efficiency of terminal-executed routing policy switching.

[0070] The technical solutions of this disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wide Band Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), and LTE Frequency Division Duplex (FDD).

[0071] The steps described above in this example implementation will now be explained in more detail.

[0072] In step S320, it is detected that the terminal accesses the roaming network and the routing policy executed by the terminal is inconsistent with the roaming policy. The roaming network and the roaming policy have a corresponding relationship.

[0073] User Equipment Route Selection Policy (URSP) is the routing policy executed by a user's terminal. The routing policy executed by the terminal can be a pre-configured policy within the terminal or received from the user's Home Policy Control Function (PCF). However, under normal circumstances, in non-3GPP standards, the terminal executes the routing policy issued by the Home PCF; a pre-configured routing policy is only used when the terminal does not receive a routing policy from the Home PCF. The URSP can be used by the user equipment to determine whether a detected application can be associated with an established Protocol Data Unit (PDU) session, whether it can be offloaded to 3GPP access outside the PDU session, or whether it can trigger the establishment of a new PDU session. The terminal can also use URSP to select matching slices, DNNs, session and service continuity modes, and other parameters to access the 5G network.

[0074] Different regions have different local policies, and each region typically has specific policy requirements. A terminal corresponds to only one home location, and the routing policy executed by the user terminal matches that home location. When a user uses the network in another region, they connect to a roaming network, also known as a visited network. The region corresponding to this roaming network is the roaming location, which has its own local policies and specific policy requirements.

[0075] In step S330, a new routing policy is obtained based on the roaming policy and the routing policy executed by the terminal.

[0076] In this embodiment, the roaming policy and the routing policy executed by the terminal in its home location may be the same or not entirely the same, i.e., partially the same and partially different. A new routing policy is obtained based on the roaming policy and the routing policy executed by the terminal. This can be achieved by merging the roaming policy and the routing policy executed by the terminal into a new routing policy. The merged routing policy includes all routing policies executed by the roaming location and the current terminal. Alternatively, it can be based on the roaming policy, retaining all policies executed by the current terminal, comparing the current terminal's policy with the roaming policy, and adding the portions included in the roaming policy but not included in the terminal's policy to the terminal's policy.

[0077] For example, the policy could be about the allowed service types, data rates, packet error rates, whether the service is real-time or non-real-time, etc. For instance, if the policy issued by the home PCF includes three aspects: A1, B1, and C2, and the roaming policy is D1 and E2, then the new route policy would be A1, B1, C2, D1, and E2; if the policy issued by the home PCF includes three aspects: A1, B1, and C2, and the roaming policy is B2 and C1, then the new routing policy would be A1, B2, and C1.

[0078] It is understandable that when roaming policies and the home location policies executed by the terminal are merged, they can be based on preset rules to achieve a certain purpose. For example, the basic principle is to select the lowest quality of service and the strictest billing rules. Therefore, when the routing policy executed by the terminal represents voice-type services and the roaming policy represents streaming media-type services, when a new routing policy is obtained based on the roaming policy and the routing policy executed by the terminal, the streaming media-type services will be included as the content of the new policy. This embodiment of the disclosure does not impose any special restrictions on the preset rules.

[0079] In step S340, the new routing policy is sent to the terminal, and the terminal executes the new routing policy.

[0080] In this embodiment of the disclosure, the PCF is a standard 5GC network element, equivalent to the PCRF in the 4G PEC. The PCF obtains the user terminal subscription policy from the Unit Deployment Manager (UDM), and issues the Access and Mobility Management Function (AMF) and Session Management Function (SMF). The AMF and SMF then issue the policies to the user terminal equipment, the Radio Access Network (RAN), and the User Plane Function (UPF).

[0081] Since roaming policies differ across regions, it is necessary to obtain the roaming policy when a new routing policy is derived based on the roaming policy and the routing policy executed by the terminal. This is to facilitate the timely generation of the new policy based on the roaming policy and the routing policy executed by the terminal device.

[0082] Based on this, this disclosure also proposes an implementation method for implementing a dynamic terminal strategy. For example... Figure 4 As shown, before the step of detecting that the terminal accesses the roaming network and that the routing policy executed by the terminal is inconsistent with the roaming policy, the method further includes step S310:

[0083] In step S310, multiple roaming policies are obtained and stored in a network policy library. The network policy library also includes area identifiers corresponding to the roaming policies.

[0084] In this embodiment, the home PCF may request roaming policies for the region from PCFs in other roaming locations. For example, the home PCF may send a request to the PCFs in other roaming locations, download the roaming policies, and finally store the policies obtained by the home PCF in the network policy database. The network policy database is located in a network element, which is managed by a network element management system. Alternatively, the network element management system can directly configure the network policy database within the network element. The network element storing the network policy database can be dynamically accessed by the home PCF.

[0085] When storing policies in the network policy library, different policies can be stored with different identifiers. These identifiers can be Public Land Mobile Network Identity Documents (PLMN IDs) or Tracking Area (TA) lists. TAs are a new concept established by the Long Term Evolution (LTE) system for user equipment location management. When a user equipment is idle, the core network can determine its tracking area. When an idle user equipment needs to be paged, paging must be performed in all cells within the tracking area where the user equipment is registered. The LTE Tracking Area Identity is composed of the PLMN and the Tracking Area Code (TAC). Multiple TAs form a TA list, which is assigned to a single user equipment. When a user equipment moves within this TA list, it does not need to perform a TA update, reducing frequent interactions with the network. When a user equipment enters a new TA area not in its registered TA list, a TA update is required. The Mobility Management Entity (MME) reassigns a new set of Traveling Targets (TAs) to User Equipment (UEs). The newly assigned TAs may also include some TAs from the existing TA list; each cell belongs to only one TA. The identifier corresponding to the policy represents the relevant roaming policy and the roaming area.

[0086] By implementing embodiments of this disclosure, multiple roaming location policies are obtained and stored in a network policy database, which also includes area identifiers corresponding to the roaming location policies. This allows for the convenient acquisition of new routing policies after a terminal accesses a roaming network, based on the roaming location policies and the routing policies executed by the terminal, thus improving the ease and efficiency of routing policy switching.

[0087] This disclosure also proposes an implementation method for a terminal dynamic policy, wherein the step of detecting that the terminal accesses the roaming network and that the routing policy executed by the terminal is inconsistent with the roaming policy includes:

[0088] Obtain the area identifier corresponding to the network accessed by the terminal, and identify the area identifier corresponding to the accessed network to determine that the terminal has accessed a roaming network;

[0089] If the policy list sent by the terminal has not changed, it is determined that the routing policy executed by the terminal is inconsistent with the roaming policy.

[0090] In this embodiment, the region identifier corresponding to the terminal can be determined by the network the terminal is currently connecting to. The region identifier is used to determine whether to access a roaming network (i.e., a visited network). When issuing user equipment policies to the terminal, the user equipment policy is divided into one or more sections for transmission. Each section corresponds to an identifier, namely the Policy Section Identifier (PSI). When a change is detected in the policy list sent by the terminal, it indicates that the terminal is no longer connected to a network in the previous region. If it was previously connected to a network in its home region, it is now in a roaming region; if it was previously connected to a network in a roaming region, the terminal may now be in its home region or another roaming region. If the policy list sent by the terminal has not changed, the routing policy executed by the terminal has not changed, indicating that although the network the terminal is connected to has changed, the routing policy executed by the terminal has not changed, and the policy needs to be modified to meet the policy requirements of the network connection region.

[0091] This disclosure also proposes an implementation method for a terminal dynamic policy. Before the step of obtaining a new routing policy based on the roaming policy and the routing policy executed by the terminal, the method further includes:

[0092] Based on the area identifier corresponding to the network accessed by the terminal, query the roaming policy corresponding to the area identifier from the network policy database;

[0093] Based on the policy identifier sent by the terminal, the routing policy executed by the terminal is obtained from the unified database, and the policy identifier corresponds to the routing policy executed by the terminal.

[0094] In this embodiment, before obtaining a new routing policy based on the roaming location policy and the routing policy executed by the terminal, it is necessary to first obtain the roaming location policy and the routing policy currently executed by the terminal. This can be done by accessing the network policy library based on the mapping between area identifiers and roaming policies in the network policy library, requesting the relevant roaming policy. For example, the home PCF queries the network policy library for special policy requirements for the visited network based on the PLMN ID or TA. The network policy library will return the special policy requirements for the visited location to the home PCF based on the received PLMN ID or TA information. The routing policy executed by the terminal can be obtained from the Unified Data Repository (UDR).

[0095] By implementing embodiments of this disclosure, roaming policies are first retrieved from the network policy library, and the routing policies executed by the terminal are retrieved from the unified database before new routing policies are obtained. This facilitates the rapid generation of new routing policies and improves the efficiency of policy modification.

[0096] Because the network to which the terminal device connects and the routing policy executed by the terminal can be constantly changing—that is, from the home location to the roaming location, from the roaming location back to the home location, and from one roaming location to another—the connected network and the executed routing policy also change as the terminal's location changes.

[0097] Based on this, this disclosure also proposes an implementation method for a terminal dynamic policy. After the step of sending the new routing policy to the terminal and the terminal executing the new routing policy, the method further includes:

[0098] Obtain the area identifier corresponding to the network accessed by the terminal, and identify the area identifier corresponding to the accessed network to determine that the terminal has accessed its home network;

[0099] The routing policy corresponding to the home network is sent to the terminal, and the terminal executes the routing policy corresponding to the home network.

[0100] In the embodiments of this disclosure, the area identifier corresponding to the terminal accessing the network can be obtained after each time the terminal device switches to a different network, or it can be obtained within a fixed time period. For example, the area identifier corresponding to the terminal accessing the network can be obtained every hour, or other time periods can be used; this disclosure does not impose any limitations on this.

[0101] After obtaining the area identifier corresponding to the terminal's access network and identifying the area identifier to determine that the terminal has accessed its home network, the policy corresponding to that home network can be directly sent to the terminal device, and the terminal executes the policy. Alternatively, the policy can be modified from the home location to the roaming location, similar to the aforementioned approach, by modifying the routing policy sent from the home location to the terminal based on the roaming policy to obtain a new policy. Correspondingly, the current terminal execution policy can be modified based on the home location policy to meet the home location policy requirements.

[0102] Based on the above embodiments, it can also be concluded that... Figure 5The diagram illustrates the implementation process of the terminal dynamic policy. Step 1: First, a new network policy library is added and configured, storing roaming policies for each region. Step 2: It is determined whether the routing policy executed by the terminal needs to be updated. This involves first checking if the terminal is connected to a roaming network, and then checking if the terminal's routing policy has changed. Step 3: The home PCF retrieves the roaming policy from the network policy library and the currently executed routing policy from the unified database. Step 4: Based on the roaming policy and the terminal's currently executed routing policy, a new routing policy is modified and distributed to the terminal. Step 5: The terminal device executes the new routing policy.

[0103] like Figure 6 The diagram shows the interaction between the terminal and the routing policy during the update process. The interaction process is divided into home and roaming areas; please refer to the scheme in the aforementioned embodiment for details, which will not be repeated here.
