As shown in FIG. 3, the communication method provided by the embodiment of the present invention includes the following steps S11-S13:

S11 , the access network device 2 acquires the operator parameter and the network identifier from the terminal 1 . Wherein, the network identifier is determined by the terminal 1 according to the service type of the initiated service.

Specifically, the access network device 2 may determine the operator parameter of the terminal 1 through a system information type 1 (system information type 1, SIB1) message that carries the operator parameter reported by the terminal 1 .

Specifically, the access network device 2 may acquire the network identifier through a protocol data unit (packet data unit, PDU) session initiated by the terminal 1 .

Specifically, the terminal 1 can initiate services of different service types through mobile phone software (application, APP) installed on the terminal 1 . Exemplarily, the service type of the service initiated by the terminal 1 may be a private network service or a public network service.

S13. When it is determined that the network identifier satisfies the preset condition, the access network device 2 accesses the terminal 1 to the operator core network corresponding to the network identifier. Wherein, each operator core network corresponds to a network identifier, and the operator core network corresponding to the network identifier is an operator core network in at least one operator core network.

Specifically, the network identifier includes at least one of a private network identifier and a target address, the operator's core network includes at least one of a private network core network and a public network core network, and the target address corresponding to the private network core network and the public network core network The target address corresponding to the network is different, S13 includes:

When the terminal 1 determines that the service type of the initiated service is a private network service, it can be seen from Table 2 that the network identifier sent by the terminal 1 to the access network device 2 is "private network identifier (eg "Z") + target address".

Then, after receiving the network identifier "Z+target address" sent by the terminal 1, the access network device 2 determines the carrier to which the terminal 1 belongs (eg, operator A) according to the carrier information of the terminal 1, thereby determining that the terminal 1 can access carrier core network.

In practical applications, since each operator includes at least one private network core network, and each private network core network provides services for different terminals 1, the access network device 2 determines that the network identifier includes the private network identifier and the target. When the address is used, the terminal 1 needs to be connected to the core network of the private network corresponding to the target address in operator A, so as to ensure the user experience.

or,

When the terminal 1 determines that the type of service initiated by the service is a public network service, it can be seen from Table 2 that the network identifier sent by the terminal 1 to the access network device 2 is the "target address".

When the service type includes 2B and 2C of the VPC, since the terminal can determine the network identifier according to the service type, the base station can determine the service type of the service initiated by the terminal according to the network identifier obtained from the terminal, which solves the problem of how the co-built base station can distinguish the 2B and 2C for each operator.

As is known to all, since the core networks of operators that provide service services for terminals of different service types are different, when the access network device determines that the network identifier satisfies the preset condition, the terminal is connected to the core network of the operator corresponding to the network identifier, and The operator's core network corresponding to the network identifier is an operator's core network in at least one operator's core network, so that terminals of different service types of the same operator can be connected to the corresponding operator's core network.
