Abstract:
1. A method for intercommunicating between a private network user and a network with QoS guarantee, comprising: carrying identity information of the private network user in a request message transmitted from the private network user to a relevant function entity of the network with QoS guarantee; translating, by the relevant function entity, the identity information of the private network user to a public address, and establishing a correspondence between the identity information and the public address; establishing a connection with an opposite end using the public address, and implementing information interaction between the private network user and the opposite end of the network with QoS guarantee based on the connection; wherein, the relevant function entity is one of an Application Function entity and a Service Boundary Control Function entity; wherein, according to the request message transmitted from the private network user, the Application Function entity or the Service Boundary Control Function entity initiates a request message for applying public address to a Policy Decision Function or Bearer Control Function; the Policy Decision Function or the Bearer Control Function applies the public address for the private network user to an address translation gateway, and the address translation gateway allocates the corresponding public address for the private network user and returns the corresponding public address to the Policy Decision Function or the Bearer Control Function; and the Policy Decision Function or the Bearer Control Function returns the public address to the Application Function entity or the Service Boundary Control Function entity for saving, or saves the public network address on the Policy Decision Function or the Bearer Control Function.
