METHOD AND DEVICE FOR ESTABLISHING ASSOCIATION-CONTROL RELATIONS

摘要

A method for establishing association-control relations includes these steps: a first network entity acquires address information of a second network entity; and the first network entity sends its own address information to the second network entity. A system, an access adapting unit, and an IMS CS control function (ICCF) for establishing association-control relations are also provided. In embodiments of the present invention, an access adapting unit such as a local-CS access adaptation function-network (L-CAAF-n) may know whether a user is an IMS centralized service (ICS) user and acquire the ICCF address information so that association-control relations may be established between the L-CAAF-n and the ICCF.
