Abstract: An access management entity receives a first connection request message used to request to establish a connection between an access network device and a mobility management entity and sends a second connection request message to the mobility management entity. The second connection request message is used to request to establish a connection between the access management entity and the mobility management entity. The mobility management entity is determined based on user access information included in the first connection request message. The access management entity receives a second connection response message indicating information about the connection between the access management entity and the mobility management entity. The access management entity sends a first connection response message indicating information about a connection between the access network device and the access management entity to the access.
