The service connection method provided in 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 service connection equipment firstly acquires first service connection information, second service connection information and service priority information, determines a currently connected service of the terminal according to the first service connection information and the second 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 method comprises the steps of determining the service priority information flow by the service connection equipment, obtaining the first service connection information flow by the service connection equipment, obtaining the second service connection information flow by the service connection equipment and determining the service connection strategy flow by the service connection equipment.

The following describes a "process of determining service priority information by a service connection device".

As shown in fig. 4, the "flow of determining service priority information by the service connection device" includes S401 to S403.

S401, the service connection equipment obtains the quality of service QOS and the resource allocation of the terminal and keeps the priority ARP.

Specifically, in the interaction process between the terminal and the first core network, when a Protocol Data Unit (PDU) session is established between the terminal and the first UPF device, the first UPF device issues a quality of service (QOS) and a resource Allocation Retention Priority (ARP) to the first SMF device. Subsequently, the service connection device may obtain the quality of service QOS and the resource allocation retention priority ARP of the terminal from the first SMF device.

Correspondingly, in the interaction process between the terminal and the second core network, the service connection device may obtain the quality of service QOS and the resource allocation retention priority ARP of the terminal from the second SMF device.

And S402, the service connection equipment determines service priority information according to QOS and ARP.

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.

After obtaining the service quality QOS and the resource allocation holding priority ARP of the terminal, the service connection equipment determines the service priority information according to the QOS and the ARP. Since the terminal is a multi-card terminal, the service of the terminal includes: the terminal establishes a connection or a service to be established with the first AMF device according to the first communication card, and establishes a connection or a service to be established with the second AMF device according to the second communication card. 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 service connection 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 service connection device stores the service priority information in the form of a table, the service 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

Service identification	Priority of service
		Voice service	Grade	10
WeChat service	Grade 9
		Game business	Stage 8
…	…
		Default services	Level	1

S403, the service connection device determines the priority of the first service and the priority of the second service according to the service priority information.

After the service priority information is determined, the service priority information includes the identifier and the priority of the first service and the identifier and the priority of the second service, so that the service connection device determines the priority of the first service and the priority of the second service according to the service priority information.

Next, a description is given to a "process of acquiring the first service connection information by the service connection device".

As shown in fig. 5a, the "process of acquiring the first service connection information by the service connection device" includes S501-S504.

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

The first service connection information is used for representing the connection state of the terminal according to the service between the first communication card and the first core network equipment; the connection state includes: a connection to be established and an established connection.

Specifically, after the terminal successfully registers with the first core network device, a Protocol Data Unit (PDU) session may be established with the first UPF device through different communication cards. In this case, the first UPF device performs service packet matching based on the packet detection rule and starts a timer. And when the first UPF equipment receives the uplink data packet of the terminal service, the timer starts to time, and when the next uplink data packet of the service is received, the timer is set to be 0 for re-timing. And then, the first UPF equipment reports the data packet matching information to the first SMF equipment, wherein the information comprises the data packet detection rule information. And then, the first SMF device forwards the content of the data packet detection rule reported by the first UPF device to the first AMF device, and the first AMF device performs paging strategy rule matching based on the content of the data packet detection rule received from the first SMF device. If the matching is successful, the connection state of the corresponding service is 'connection established'. If the first 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'.

For example, the first UPF device may obtain the first service connection information of the terminal with the communication card id of card 1 as shown in table 2.

TABLE 2

Optionally, the packet detection rule may be a packet detection rule matching a specific service, or may be a default packet detection rule (that is, all packets that are not matched to 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 first UPF device, the first SMF device issues a packet detection rule to the first UPF device. Multiple QOS flows can be established in each PDU session, each QOS flow corresponds to a service, and the packet detection rule of the UPF device is performed according to the QOS flow granularity.

S502, the service connection equipment sends a first request message to the first UPF equipment.

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

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

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

And S504, the service connection equipment determines that the first service is a service for which the terminal is to establish connection with the first core network equipment according to the first communication card according to the first service connection information.

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

The following describes a "process of acquiring the second service connection information by the service connection device".

As shown in fig. 5b, the "process of acquiring the second service connection information by the service connection device" includes S505 to S508.

And S505, the second UPF equipment acquires second service connection information of the terminal.

The second service connection information is used for representing the connection state of the terminal according to the service between the second communication card and the second core network equipment; the connection state includes: a connection to be established and an established connection.

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

For example, the second UPF device may obtain the second service connection information of the terminal with the communication card id of card 2 as shown in table 3.

TABLE 3

It should be noted that, in practical application, in the process of establishing the PDU session between the terminal and the second UPF device, the second SMF device issues the packet detection rule to the second UPF device. Multiple QOS flows can be established in each PDU session, each QOS flow corresponds to a service, and the packet detection rule of the UPF device is performed according to the QOS flow granularity.

And S506, the service connection equipment sends a second request message to the second UPF equipment.

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

And after the second UPF equipment acquires the second service connection information of the terminal, the service connection equipment sends a second request message to the second UPF equipment to acquire the second service connection information.

And S507, the service connection equipment receives second service connection information sent by the second UPF equipment.

And S508, the service connection equipment determines the second service as the service which is established by the terminal according to the second communication card and the second core network equipment according to the second service connection information.

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

The following describes "a process of determining a service connection policy by the service connection device".

As shown in fig. 6, the "flow of the service connection apparatus determining the service connection policy" includes S601-S605.

S601, the service connection device obtains the identifier of the first service and the identifier of the second service.

The first service is a service to be established for connection between the terminal and the first AMF device according to the first communication card. And the second service is the service that the terminal establishes connection with the second 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 service connection device may determine the connection state of the first service according to the first service connection information acquired in the "process of acquiring the first service connection information by the service connection device".

Correspondingly, the service connection device may determine the connection state of the second service according to the second service connection information acquired in the "process in which the service connection device acquires the second service connection information".

S602, the service connection device determines the priority of the first service according to the identifier of the first service.

Optionally, the service connection device may determine the priority of the first service according to the service priority information determined in the "process of determining the service priority information by the service connection device".

S603, the service connection device determines the priority of the second service according to the identifier of the second service.

Optionally, the service connection device may determine the priority of the second service according to the service priority information determined in the "process of determining the service priority information by the service connection device".

It should be noted that, the service connection 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 service connection device judges whether the priority of the first service is higher than that of the second service.

Optionally, the service connection device may determine, according to the service priority information, 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. And if the priority of the first service is lower than that of the second service, no operation is executed.

S605, the service connection device sends indication information to the first core network device.

The indication information is used for indicating the first core network device to initiate 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 which a connection is to be established, and the second service is a WeChat service of the card 1 to which a connection has been established, as can be seen from table 1, the priority of the voice service is higher than the priority of the WeChat service, so that the service connection device sends indication information to the first AMF device to indicate the AMF device to initiate a connection request of the first service to the terminal.
