The routing processing method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

The embodiment of the application can be applied to the following scenes: the terminal uses the urs in EPS as follows:

scene one: the UE supports 4G and 5G network capabilities. When the UE is started, the 5G network coverage is not available, and the UE is registered in the 4G network. At this point, if the 5GS updates the urs rules, then the urs in the EPS are not up to date, or the UE does not have a urs at this point.

Scene II: the UE enters the 4G mode from 5G, and long time passes for the urs to update at 5GS, but since the UE is still in EPS, the urs cannot be updated.

In order to provide a consistent routing policy (e.g., urs) for a terminal in case of multiple networks (e.g., EPS and 5 GS), as shown in fig. 2, an embodiment of the present application provides a routing processing method 200, which may be performed by a first network, in other words, by software or hardware installed in the first network, the method including the following steps.

S202: the first network obtains first information, which is used to perform a first operation.

S204: the first network performs the first operation according to the first information, wherein the first operation comprises at least one of the following steps: 1) Transmitting a fourth message for indicating a request for the recipient terminal to establish a packet data network (Packet Data Network, PDN) connection corresponding to the first parameter information; 2) A fifth message is sent, wherein the fifth message is used for indicating a request for rejecting the terminal to establish the PDN connection corresponding to the first parameter information; 3) Establishing a PDN connection by using fourth parameter information, wherein the fourth parameter information is default parameter information related to routing data used by a terminal in the first network;

4) And sending fourth indication information, wherein the fourth indication information is used for indicating the terminal to update the second parameter information.

The first parameter information is parameter information related to route data, which is used by the terminal in the first network, for example, the first parameter information is an EPS route policy parameter, and the EPS route policy parameter is obtained by a corresponding relationship between EPS and 5GS policy parameter urs in EPS. The second parameter information is parameter information related to routing data used by the terminal in the second network, for example, the second parameter information is urs used by the terminal in 5GS, etc.

In various embodiments of the present application, when the first network appears as an execution body, the first network may refer to a network side device in the first network, for example, the first network is a network side device in EPS, where the network side device may be an access network device or a core network device; accordingly, when the second network appears as an execution body, the second network may refer to a network-side device in the second network, for example, the second network is a network-side device in 5GS, and the network-side device may be an access network device or a core network device.

Optionally, the fourth message and/or the fifth message includes fifth indication information, where the fifth indication information is used to indicate any one of the following: 1) The terminal updates the second parameter information; 2) The second parameter information needs to be updated; 3) The terminal accesses a second network so as to update the second parameter information. Alternatively, the fifth indication information may be a cause value.

In one example, the first operation includes establishing a PDN connection using fourth parameter information, the method further comprising: the first network overwrites (overrides) the first parameter information to the fourth parameter information.

Optionally, the first operation further includes: the first network sends third parameter information, the third parameter information comprises parameter information related to route data used by the terminal in the second network, and the first network can acquire the third parameter information through interaction with the second network. For example, the third parameter information is updated second parameter information, and may specifically be updated urs in 5 GS.

Optionally, the third parameter information may be carried by any one of the following Non-Access Stratum (NAS) messages: 1) A PDN connection accept message; 2) The EPS network carries the context modification acceptance message; 3) Enhanced session management (Enhanced Session Management, ESM) information request message; 4) Activating a dedicated first network bearer content accept message; 5) A service acceptance message; 6) Tracking area update accept message; 7) Attach accept message.

Optionally, the third parameter information is contained in a protocol configuration option (Protocol Configuration Option, PCO) or an extended protocol configuration option (extended PCO, ePCO) information element (Information Element, IE).

Optionally, the first network obtains first information including at least one of:

1) The first network receives a first message sent by the terminal, wherein the first message comprises first indication information and/or second indication information, and the first indication information is used for indicating the terminal to acquire the first parameter information based on the second parameter information; the second indication information is used for indicating whether the terminal has or does not have the second parameter information.

For example, the first parameter information is an EPS routing policy parameter, and the first indication information is used for indicating that the terminal obtains the first parameter information based on a corresponding relationship between EPS and 5GS urs. In the related art, when the terminal sends first parameter information to the EPS to request to establish a PDN connection, the EPS cannot know how the first parameter information of the terminal is obtained, and in this embodiment, the terminal is instructed by the first instruction information to obtain the first parameter information based on the second parameter information, so that the EPS may predict that the urs p of the terminal may not be up to date, which may cause that the first parameter information is wrong, and the terminal needs to update the urs p.

For example, the second indication information is used to indicate that the terminal has or does not have a urs, so that the EPS may instruct the terminal to update or acquire a urs through the first operation.

2) The first network receives a second message sent by a second network, wherein the second message comprises third indication information, and the third indication information is used for indicating the terminal to update the second parameter information. Optionally, the second message further includes at least one of: a) Third parameter information, which is parameter information related to routing data used by the terminal in the second network, for example, the third parameter information is updated second parameter information, and may specifically be updated urs in 5 GS; b) And the identification information of the terminal.

3) The first network receives a third message sent by the terminal, wherein the third message is used for establishing PDN connection, and the third message comprises at least one of the following components: the device comprises first indication information, second indication information, first parameter information and second parameter information. The roles of the first indication information, the second indication information, the first parameter information, and the second parameter information can be referred to in the foregoing description.

4) The first network acquires the subscription information of the terminal, wherein the subscription information of the terminal comprises the subscription information of the terminal in the first network and/or the subscription information of the terminal in the second network. In this embodiment, for example, the first network learns that the terminal signs up not only on the first network but also on the second network, and the second network may possibly update the second parameter information, so the first network may instruct the terminal to update or acquire the second parameter information through the first operation.

5) The first network obtains capability information of the terminal, where the capability information of the terminal is used to instruct the terminal to support the second network, and optionally, the first message sent by the terminal may be an attach request message, where the first message carries the capability information of the terminal. In this embodiment, for example, the first network knows that the terminal supports the second network mode, and the second network has a possibility of updating the second parameter information, and thus, the first network can instruct the terminal to update or acquire the second parameter information through the first operation.

6) The first network obtains a registration state of the terminal, wherein the registration state is used for indicating the registration state of the terminal in the second network. In this embodiment, for example, the first network knows that the terminal is registered in the second network, and the second network has a possibility of updating the second parameter information, and thus the first network can instruct the terminal to update or acquire the second parameter information through the first operation.

Optionally, the first message includes at least one of: 1) A PDN connection establishment request message; 2) The EPS network carries the context modification request message; 3) ESM information response message; 4) Activating a special first network to bear a content request message; 5) A service request message; 6) Tracking an area update request message; 7) Attach request message.

According to the routing processing method provided by the embodiment of the application, the first network acquires the first information, and executes the first operation according to the first information, wherein the first operation comprises at least one of the following steps: a fourth message is sent, wherein the fourth message is used for indicating a request of an accepting terminal for establishing PDN connection corresponding to the first parameter information; a fifth message is sent, wherein the fifth message is used for indicating a request for rejecting the terminal to establish the PDN connection corresponding to the first parameter information; establishing a PDN connection by using fourth parameter information, wherein the fourth parameter information is default parameter information related to routing data used by a terminal in the first network; transmitting fourth indication information, wherein the fourth indication information is used for indicating the terminal to update the second parameter information; the first parameter information is parameter information related to route data used by the terminal in the first network; the second parameter information is parameter information related to routing data used by the terminal in a second network. The embodiment of the application is beneficial to updating the second parameter information of the terminal based on the first operation, so that the terminal can keep consistent parameter information related to the route data under the first network and the second network, normal communication of the terminal is not influenced, and the performance of a communication system is improved.

The above-mentioned is advantageous for updating the second parameter information of the terminal based on the first operation, for example, in case the first operation includes sending a fourth message for indicating to accept a request for the terminal to establish a PDN connection corresponding to the first parameter information, i.e. even if the first parameter information may be erroneous (since the terminal generates the first parameter information based on the second parameter information, which may not be up-to-date), the first network allows the terminal to establish the PDN connection corresponding to the first parameter information, the terminal may first use the PDN connection corresponding to the first parameter information, and obtain the third parameter information, i.e. the updated second parameter information, if there is a second network coverage, in order to update the second parameter information of the terminal based on the first operation. In addition, the fourth message may further include fifth indication information for indicating any one of: 1) The terminal updates the second parameter information; 2) The second parameter information needs to be updated; 3) The terminal accesses to a second network so as to update the second parameter information, and the second parameter information of the terminal is further updated by the fifth indication information included in the fourth message.

For another example, in the case where the first operation includes sending a fifth message for indicating to reject the request for the terminal to establish the PDN connection corresponding to the first parameter information, the terminal may learn that the first parameter information may be erroneous, that is, the second parameter information may not be up-to-date, and the terminal may acquire the third parameter information, that is, the updated second parameter information, when there is coverage of the second network, which is advantageous for updating the second parameter information of the terminal based on the first operation. In addition, the fifth message may further include fifth indication information for indicating any one of: 1) The terminal updates the second parameter information; 2) The second parameter information needs to be updated; 3) The terminal accesses to a second network so as to update the second parameter information, and the second parameter information of the terminal is further updated by the fifth indication information included in the fifth message.

For another example, in the case where the first operation includes setting up a PDN connection using the fourth parameter information, the terminal may learn that the first parameter information may be erroneous, that is, the second parameter information may not be up-to-date, and the terminal may acquire the third parameter information, that is, the updated second parameter information, in the case where there is the second network coverage, so as to facilitate updating the second parameter information of the terminal based on the first operation.

For another example, the first operation includes sending fourth indication information, where the fourth indication information is used to instruct the terminal to update the second parameter information, so that the terminal may obtain third parameter information when there is a second network coverage, where the third parameter information is updated second parameter information, and updating the second parameter information of the terminal based on the first operation is facilitated.
