Description

Service connection method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a service connection method and apparatus.

Background

With the development of communication technology, the dual card terminal provides great convenience for users.

A user may install two different Universal Subscriber Identity Module (USIM) cards (e.g., USIM card 1 and USIM card 2) in the same terminal to handle different services. For example: the USIM card 1 is used for making and receiving calls, and the USIM card 2 is used for using flow services; or the USIM card 1 is used for handling work and the USIM card 2 is used for personal life.

However, at present, the dual-card terminal cannot support the simultaneous use of two different USIM cards. Under the background, when the USIM card 1 in the dual-card terminal is in a service process, the USIM card 2 cannot be normally used; or when the USIM card 1 is in a service process, after the USIM card 2 triggers the service, the service in progress of the USIM card 1 may be interrupted, which reduces user experience.

As described in the background art, when the USIM card 1 in a dual card terminal is in a service process, the USIM card 2 cannot be normally used; or when the USIM card 1 is in a service process, after the USIM card 2 triggers the service, the service in progress of the USIM card 1 may be interrupted, which reduces user experience.

In view of the foregoing problems, an embodiment of the present application provides a service connection method, including: the AMF equipment determines the priority of the first service and the second service according to the identifier of the first service and the identifier of the second service, and determines a service connection strategy according to the priority of the first service and the priority of the second service. Whether the service which is established by the terminal is interrupted is determined according to the priority of the service, the connection sequence is reasonably distributed for the services corresponding to a plurality of communication cards in the multi-card terminal, and the user experience is improved.

The service connection method provided by the embodiment of the present application is applicable to the communication system 10. Fig. 1 shows one configuration of the communication system 10. As shown in fig. 1, the communication system 10 includes: terminal 11, radio access network device 12, AMF device 13, UPF device 14, SMF device 15, and PCF device 16.

Wherein, the terminal 11 is in communication connection with the radio access network equipment 12. The terminal 11 is connected with the AMF device 13 through an N1 interface. The radio access network device 12 and the AMF device 13 are connected by an N2 interface. The radio access network device 12 interfaces with the UPF device 14 via an N3 interface.

Terminal 11 in the embodiments of the present application may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal may communicate with one or more core networks via a Radio Access Network (RAN). The wireless terminals may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, as well as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices that exchange language and/or data with a wireless access network, such as cell phones, tablets, laptops, netbooks, Personal Digital Assistants (PDAs).

It should be noted that the terminal in the embodiment of the present application supports simultaneous installation of a plurality of communication cards. Because the AMF device, the UPF device, the SMF device, and the PCF device are all core network devices in the same core network, and one core network corresponds to one operator, when the terminal in the embodiment of the present application includes a plurality of communication cards, the plurality of communication cards are communication cards under the same operator.

The communication card may be a Universal Subscriber Identity Module (USIM) card, a SIM card in a global system for mobile communications (GSM) system, or a UIM card in a CDMA (code division multiple access) system, which is not limited in the embodiments of the present invention.

When the embodiment of the present application is applied to a communication system of other mobile communication technologies, the device of the 5G core network may be a core network device having the same function in the communication system of other mobile communication technologies. For example: the function of the PCF apparatus is the same as that of a Policy and Charging Rules Function (PCRF) apparatus in the 4G core network. Therefore, when the embodiment of the present application is applied to a 4G communication system, the PCF device in the embodiment of the present application may be replaced with a PCRF device.

In a possible implementation, the memory 22 may exist separately from the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 for storing instructions or program codes. The processor 21 can implement the service connection method provided by the embodiment of the present invention when calling and executing the instructions or program codes stored in the memory 22.

In another possible implementation, the memory 22 may also be integrated with the processor 21.

It should be noted that the structure shown in fig. 2 does not constitute a limitation to the service connection device. The service connection means may comprise more or less components than those shown in figure 2, or some components may be combined, or a different arrangement of components than those shown.

Fig. 3 shows another hardware structure of the service connection apparatus in the embodiment of the present application. As shown in fig. 3, the service connection device may include a processor 31 and a communication interface 32. The processor 31 is coupled to a communication interface 32.

The function of the processor 31 may refer to the description of the processor 21 above. The processor 31 also has a memory function, and the function of the memory 22 can be referred to.

The communication interface 32 is used to provide data to the processor 31. The communication interface 32 may be an internal interface of the service connection device, or may be an external interface (corresponding to the communication interface 23) of the service connection device.

It is noted that the configuration shown in fig. 2 (or fig. 3) does not constitute a limitation of the service connection device, which may comprise more or less components than those shown in fig. 2 (or fig. 3), or a combination of certain components, or a different arrangement of components, in addition to the components shown in fig. 2 (or fig. 3).

The service connection method provided by the embodiment of the present application is described in detail below with reference to the power supply device shown in fig. 1 and the service connection apparatus shown in fig. 2 (or fig. 3).

The method for providing the service connection comprises the following steps: the AMF equipment firstly acquires service connection information and service priority information, determines a currently connected service of the terminal according to the service connection information, determines the priority of a service to be connected and the priority of the connected service according to the service priority information, and determines a service connection strategy according to the priority of the service to be connected and the priority of the connected service. Therefore, the method for providing service connection in the embodiment of the present application includes: the flow of the AMF device acquiring the service priority information, the flow of the AMF device acquiring the service connection information, and the flow of the AMF device determining the service connection policy are described.

The "flow of acquiring the service priority information by the AMF device" will be described first.

As shown in fig. 4, the "flow of acquiring the service priority information by the AMF device" includes S401 to S404.

S401, the AMF equipment acquires a terminal identification of the terminal.

Specifically, when the terminal sends a registration request to the AMF device, the registration request carries a terminal identifier of the terminal. The AMF device may obtain the terminal identifier of the terminal from a registration request sent by the terminal. The terminal identification includes: a permanent subscription identifier (SUPI) and a multi-card identifier. The SUPI is a unique identification of the terminal used to label the terminal. The multi-card identifier is used for indicating that the terminal supports the simultaneous installation of a plurality of communication cards.

S402, if the AMF equipment determines that the terminal identification is the multi-card identification, the AMF equipment sends a first request message to PCF equipment.

The first request message is used for requesting to acquire service priority information. The service priority information comprises a plurality of service identifications and a plurality of priorities; the plurality of service identifications and the plurality of priorities correspond to one another. The service priority information includes: the identity and priority of the first service, the identity and priority of the second service.

If the AMF equipment determines that the terminal identifier is a multi-card identifier, a first request message for requesting to acquire service priority information is sent to the PCF equipment, so that the priority of a first service (namely, a service to be connected) and the priority of a second service (namely, a connected service) are determined according to the service priority information subsequently.

And if the AMF equipment determines that the terminal identifier is the single-card identifier, no operation is executed.

S403, the AMF device receives the service priority information sent by the PCF device.

After receiving the first request message sent by the PCF device, the PCF device sends service priority information to the AMF device.

Specifically, when the terminal signs a contract with the operator, the PCF apparatus sets different priorities for each service according to the service identifier of the terminal. Since the terminal is a multi-card terminal, the service of the terminal includes: the terminal establishes the connection or the service of the connection to be established according to the first communication card and the AMF equipment, and the terminal establishes the connection or the service of the connection to be established according to the second communication card and the AMF equipment. The first communication card and the second communication card are any two different communication cards in the terminal.

After determining the priority of each service of the terminal, the PCF device stores the service identifier and the service priority, where the storage mode may be a table form or other forms, and the application does not limit this.

Illustratively, as shown in table 1, when the PCF apparatus stores the traffic priority information in the form of a table, the traffic priority information includes: the priority corresponding to the voice service is 10 level, the priority corresponding to the WeChat service is 9 level, and the priority corresponding to the game service is 8 level.

It should be noted that, because the number of the services of the terminal is large, if the default service in the terminal services does not set the priority, the priority of the default service is the lowest, for example, level 1.

TABLE 1

S404, the AMF device determines the priority of the first service and the priority of the second service according to the service priority information.

After receiving the service priority information sent by the PCF device, the AMF device determines the priority of the first service and the priority of the second service according to the service priority information, since the service priority information includes the identifier and the priority of the first service, the identifier and the priority of the second service.

The flow of acquiring the service connection information by the AMF device will be described below.

As shown in fig. 5, the "flow of acquiring the service connection information by the AMF device" includes S501 to S505.

S501, the UPF equipment acquires service connection information of the terminal.

The service connection information is used for representing the connection state of the service of the terminal; the connection state includes: a connection to be established and an established connection.

Specifically, after the terminal successfully registers with the core network device, a Protocol Data Unit (PDU) session may be established with the UPF device through different communication cards. In this case, the UPF device performs service packet matching based on the packet detection rule and starts a timer. And when the UPF equipment receives the uplink data packet of the terminal service, the timer starts to time, and when the UPF equipment receives the next uplink data packet of the service, the timer is set to be 0 for re-timing. And then, the UPF equipment reports the data packet matching information to the SMF equipment, wherein the information comprises data packet detection rule information. Then, the SMF device forwards the data packet detection rule content reported by the UPF device to the AMF device, and the AMF device performs paging strategy rule matching based on the data packet detection rule content received from the SMF device. If the matching is successful, the connection state of the corresponding service is 'connection established'. If the UPF equipment does not receive the uplink data of the terminal service sent by the terminal within the preset time period, the timer is determined to be overtime, and the connection state of the corresponding service is changed from 'connection established' to 'connection to be established'.

It should be noted that, because the terminal is a multi-card terminal, the UPF device may obtain the service connection information of the terminal according to the services transmitted by the multiple communication cards, and the method for the UPF device to obtain the service connection information of the terminal according to the services transmitted by each communication card is the same.

Illustratively, the terminal includes a card 1 and a card 2, and the UPF device may obtain the service connection information of the terminal as shown in table 2.

TABLE 2

Optionally, the packet detection rule may be a packet detection rule matching the specific service, or may be a default packet detection rule (that is, all packets that do not match the packet detection rule of the specific service are matched to the default packet detection rule).

It should be noted that, in practical application, in the process of establishing a PDU session between a terminal and a UPF device, an SMF device issues a data packet detection rule to the UPF device. Multiple QoS flows can be established in each PDU session, each QoS flow corresponds to one service, and the data packet detection rule of the UPF equipment is carried out according to the QoS flow granularity.

And S502, the AMF device sends a second request message to the UPF device.

The second request message is used for requesting to acquire the service connection information.

After the UPF device acquires the service connection information of the terminal, the AMF device sends a second request message to the UPF device to acquire the service connection information.

S503, the AMF device receives the service connection information sent by the UPF device.

And S504, the AMF equipment determines that the first service is the service to be connected between the terminal and the AMF equipment according to the first communication card according to the service connection information.

After receiving the service connection information sent by the UPF device, the AMF device determines, according to the service connection information, that the first service is a service to be connected between the terminal and the AMF device according to the first communication card, because the service connection information is used to indicate a connection state of the service of the terminal.

And S505, the AMF equipment determines that the second service is the service of which the connection between the terminal and the AMF equipment is established according to the second communication card according to the service connection information.

After receiving the service connection information sent by the UPF device, the AMF device determines, according to the service connection information, that the second service is a service for which the terminal has established a connection with the AMF device according to the second communication card, because the service connection information is used to indicate a connection state of the service of the terminal.

It should be noted that the AMF device may perform S504 first, and then perform S505; or executing S505 first and then executing S504; s504 and S505 may also be executed simultaneously, which is not limited in this embodiment of the application.

The flow of determining the service connection policy by the AMF device is described below.

As shown in fig. 6, the "flow of determining the traffic connection policy by the AMF device" includes S601-S605.

S601, the AMF equipment acquires the identifier of the first service and the identifier of the second service.

The first service is a service to be established for the terminal to connect with the AMF device according to the first communication card. And the second service is the service that the terminal establishes connection with the AMF equipment according to the second communication card. The first communication card and the second communication card are any two different communication cards in the terminal.

Optionally, the AMF device may determine the connection state of the first service and the second service according to the service connection information acquired in the "process of acquiring the service connection information by the AMF device".

S602, the AMF equipment determines the priority of the first service according to the identifier of the first service.

Optionally, the AMF device may determine the priority of the first service according to the service priority information acquired in the "process of acquiring the service priority information by the AMF device".

S603, the AMF equipment determines the priority of the second service according to the identifier of the second service.

Optionally, the AMF device may determine the priority of the second service according to the service priority information acquired in the "process in which the AMF device acquires the service priority information".

It should be noted that the AMF device may perform S602 first, and then perform S603; s603 may be executed first, and then S602 is executed; s602 and S603 may also be executed simultaneously, which is not limited in this embodiment of the application.

S604, the AMF equipment judges whether the priority of the first service is higher than that of the second service.

Optionally, the AMF device may determine, according to the service priority information acquired in the "process of acquiring the service priority information by the AMF device", whether the priority of the first service is higher than the priority of the second service. If the priority of the first service is higher than that of the second service, S605 is performed. If the priority of the first service is lower than the priority of the second service, S606 is executed.

S605, the AMF device initiates a connection request of the first service to the terminal.

Illustratively, with reference to table 1 and table 2, if the first service is a voice service of the card 2 to be connected, and the second service is a wechat service of the card 1 with an established connection, as can be seen from table 1, the priority of the voice service is higher than the priority of the wechat service, and therefore, the AMF device initiates a connection request of the first service to the terminal.

And S606, the AMF equipment and the terminal maintain the connection of the second service.

Illustratively, in combination with table 1 and table 2, if the first service is a game service of the card 2 to which a connection is to be established, and the second service is a WeChat service of the card 1 to which a connection is already established, as can be seen from table 1, the priority of the game service is lower than that of the WeChat service, and therefore, the AMF device and the terminal maintain the connection of the second service.

The application provides a service connection method which is applied to a communication system comprising a terminal and an access and mobility management function (AMF) device. Wherein the terminal is in communication connection with the AMF device. The service connection method comprises the following steps: the AMF equipment firstly acquires the identifier of the first service and the identifier of the second service, and then determines the priority of the first service according to the identifier of the first service.
