Description

Dual-card terminal paging priority determination method and dual-card terminal

Technical Field

The present disclosure relates to a method for determining a paging priority of a dual-card terminal and a dual-card terminal, and in particular to a method for determining a paging priority of a dual-card terminal based on an APN/DNN message and a dual-card terminal.

Background Art

The dual-card dual-receive single-transmit terminal can monitor the paging of two cards at the same time, but because it is a single-transmit terminal, it cannot establish a session connection on both sides at the same time. When card A is doing business and card B is paging at the same time, it is necessary to switch the transmission channel to card B to establish a connection. After receiving the message, it is known whether the paging is voice, data or RCS (Rich Communication Suite, converged communication) business, etc., and then based on the user's preference or system settings, the priority of the business is determined, and it is chosen whether to give priority to card B's business or jump back to card A to continue card A's business.

Summary of the invention

However, when card A is performing business and card B hears paging at the same time, a dual-card dual-receiver single-sender terminal needs to establish a connection with card B to determine whether to process card B's business. If the priority of card B's business is low, it will not only affect the original card A's business, but also cause a waste of signaling resources and terminal power.

DETAILED DESCRIPTION

The present disclosure proposes a method for determining the paging priority of a dual-card terminal and a dual-card terminal. By adding an APN/DNN message to a paging message, for example, when a service such as an RCS service is carried by a special APN/DNN, card B can know the service type by only monitoring and decoding the paging without establishing a data channel. At this time, based on user selection or system settings, it can be directly determined whether to return to continue the service of card A, or whether the service of card B has a higher priority and a connection needs to be established to complete the service of card B before returning to card A. The paging priority can be quickly determined, the impact of low-priority services on high-priority services can be minimized, unnecessary impact on the service of card A can be reduced, air interface signaling resources can be saved, and terminal power consumption can be reduced.

Among them, the APN (Access Point Name) under 4G determines the access method used by the user's mobile phone to access the mobile network. The name is changed to DNN (Data Network Name) under 5G. The terminal can support multiple APN/DNN access only through the support of software protocols, or the terminal itself can support multiple APN/DNN access. Special services will be carried through a separate APN/DNN, such as Volte (Voice over Long-Term Evolution) or RCS.

FIG. 1 is a diagram showing an example of a paging process of a dual-SIM terminal.

In Figure 1, UPF (User Port Function), SMF (Session Management Function), and AMF (Access and Mobility Management Function) belong to the core network. (R)AN (Radio Access Network) is a base station, and UE (User Equipment) is a user device, such as a mobile terminal.

The difference between FIG1 and the existing 5G paging process is that in the existing paging process, the DNN message is not carried when data is transmitted in steps 2c, 3a, 4b, and 4c. In FIG1, the DNN message is carried when data is transmitted in steps 2c, 3a, 4b, and 4c. FIG1 lists the case where the DNN message is carried in the 5G paging process, but the APN message can also be carried in the 4G paging process.

Here, since APN/DNN is mainly controlled by the operator, the operator can make the downlink data carry APN/DNN messages when transmitting, for example, downlink data from UPF to SMF.

Afterwards, the APN/DNN message is also carried in the paging message, and the operator's various services are carried by the operator on different APN/DNNs. For example, the Volte voice service is carried on the first APN/DNN, the RCS service is carried on the second APN/DNN, and the data service is carried on the third APN/DNN. The same correspondence table, that is, the service-APN/DNN correspondence table, is pre-stored on the terminal. The service type is not limited to Volte voice service, RCS service, and data service, but can also be other services, and carried on different APN/DNNs.

In addition, for example, the priority of Volte voice service is higher than that of RCS service, and the priority of RCS service is higher than that of data service. The priority order can be pre-set in the dual-card terminal and pre-stored in the dual-card terminal, or pre-set by the operator and stored in the dual-card terminal. However, it is not limited to this, and the dual-card terminal or the operator can set a service priority order table different from the above service priority order according to its own needs.

FIG. 2 is a diagram showing an example of a dual-SIM terminal paging priority determination process.

First, assume that the dual-card terminal has card A and card B, card A is in service, and card B monitors paging.

In step 11, when card A is in service state and card B monitors a paging message, the APN/DNN message attached to the paging message monitored by card B is compared with the service-APN/DNN correspondence table pre-stored in the dual-card terminal to analyze the type of service of the paging of card B.

Specifically, when card A is in service mode, the RF front end will be periodically switched (tuned away) to card B to monitor paging. When card B monitors paging, it decodes the APN/DNN message carried in the paging message. The dual-card terminal compares the APN/DNN message carried in the paging message with the service-APN/DNN correspondence table pre-set on the dual-card terminal to analyze the service type of card B's paging.

In step 12, according to the service priority sequence table pre-stored in the dual-card terminal, it is determined whether the analyzed priority of the paging service of card B is lower than the priority of the service of card A.

If it is determined that the priority of the paging service of card B is lower than that of the service of card A, the process proceeds to step 13. If it is determined that the priority of the paging service of card B is higher than that of the service of card A, the process proceeds to step 14.

In step 13, the paging of card B is not processed, and the RRC (Radio Resource Control) connection of card B is not established. Card A is directly switched back to continue the service of card A, thereby reducing the impact on the high priority service of card A.

In step 14, an RRC connection is established on card B to carry out the service of card B. After the service of card B is completed, the service of card A is returned.

When it is determined that the priority of the paging service of card B is the same as the priority of the service of card A, the process proceeds to step 15 .

In step 15, it is determined whether the paging service of card B is a Volte voice service. If it is determined that the paging service of card B is a Volte voice service, the process proceeds to step 16. If it is determined that the paging service of card B is not a Volte voice service, the process proceeds to step 13.

In step 16, a connection with card B is established, and the paging information of card B is displayed. The user chooses whether to answer the paging of card B or switch back to card A to continue the service of card A.

In step 13, as described above, the paging of card B is not processed, the RRC connection of card B is not established, and the card A is directly switched back to continue the service of card A, thereby reducing the impact on the high priority service of card A.

That is, when it is determined that the priority of the paging service of card B is the same as that of the service of card A, only when the paging service of card A and card B is Volte voice service, the connection of card B is established, the paging information of card B is displayed, and the user chooses whether to answer the paging of card B or switch back to card A to continue the service of card A. When the paging service of card A and card B is RCS service or data service, the paging of card B is not processed, the RRC connection of card B is not established, and the card A is directly switched back to card A to continue the service of card A. In this way, for services with relatively high requirements that need to be processed in time, such as Volte voice service, the user can choose whether to answer the call of card B or continue to answer the call of card A, so that more important services for the user can be processed in time.

Specific embodiments are described below.

For example, card A is in the Volte voice service. In addition, it is assumed that the dual-card terminal compares the APN/DNN message carried in the paging message with the service-APN/DNN correspondence table pre-stored on the dual-card terminal and analyzes that the service type of the paging of card B is a data service. Since the priority of the data service of card B is lower than the priority of the Volte voice service of card A, the paging of card B is not processed, the RRC connection of card B is not established, and the card A is directly switched back to complete the Volte voice service of card A, thereby reducing the impact on the high-priority service of card A.

As described above, according to the present disclosure, by carrying the APN/DNN message in the paging message and carrying the service on different APN/DNN, it can be achieved that when card B receives the paging message, it can determine the service type by only judging the APN/DNN message in the paging message, and then compare the service priority with the service of card A, and then decide whether to establish the RRC connection of card B to receive data. Therefore, it is possible to reduce unnecessary impact on the service of card A, and reduce the waste of signaling and terminal power. That is to say, when the service priority of card B is lower than the service priority of card A, there is no need to establish the RRC connection of card B to receive data and then switch back to card A after discovering the low situation. Therefore, it is possible to reduce the impact on the high-priority service of card A, while saving signaling and terminal power waste.

In addition, for example, operators can easily make personalized settings based on their own business needs. That is, since APN/DNN is mainly controlled by operators, when operators want to introduce customized special services, such as 5G message RCS services, they can carry the RCS service on an independent APN/DNN, thereby conveniently controlling the priority of the service.

According to the present disclosure, the modification of signaling is small, and it is only necessary to carry the APN/DNN message in the paging message, that is, there is no need to introduce additional paging parameters in the signaling to determine the corresponding service, and the service-APN/DNN correspondence table comparison and priority determination are placed on the terminal side, saving air interface signaling resources.

According to the present disclosure, the existing APN/DNN is combined with the paging service and its priority, reducing the impact on the main card service and reducing power consumption without introducing new signaling.

According to the present disclosure, dual-card terminals can support multiple APN/DNN access only through the support of software protocols, thus having better scalability, and special services are generally carried through different APN/DNN carriers (such as Volte, RCS, etc.), which is in line with current business characteristics.

In addition, the computer-readable storage medium includes computer-executable instructions, which, when executed by one or more processors, enable the one or more processors to execute the method for determining the paging priority of a dual-card terminal of the present disclosure.
