METHOD AND SYSTEM TO ESTABLISH RELATION BETWEEN SERVICE NETWORK ELEMENT AND MME AND USER EQUIPMENT

摘要

The present invention provides a method, system and UE for establishing association between a service network element and an MME, in order to solve the technical problem of establishing association between the service network element and the MME. The technical solution of the present invention is as follows: the service network element receives a message sent by the UE including an information parameter of the MME which is currently serving the UE, and acquires the information parameter of the MME from the message; the service network element sends a message including an information parameter of the service network element to the MME; and the MME acquires the information parameter of the service network element from the message. The present invention realizes the requirement of establishing association between the service network element and the MME without modifying and upgrading network elements related to the PCC architecture for implementing the function, reduces the operating cost and risk of the existing network, and favours the prompt application of the EPS network.
