Method for processing request for network address/port translation in communication network
A method for processing request for network address/port translation in a communication network includes: firstly, the first network entity transmits a network address/port request message which carries the priority information of the request; after receiving the request, the second network entity allocates the corresponding network address/port for the first network entity according to the priority information in the request message; finally, the second network entity returns the allocated network address/port information to the first network entity, and the allocated network address/port information is used for performing the network/address translation. By realizing the invention, the service having high priority, e.g. emergency service, can be processed for the network/address translation firstly to ensure the reliability of high priority service communication. Furthermore, it can provide distinguished process service of the network address/port translation during a network operation, and thereby enhancing the flexibility of the network operation.
