Method for establishing access signaling channel for service continuity between user terminals e.g. mobile phones, in mobile telephone network, involves providing information, for inhibiting initial verification filter criteria, to server

摘要

The method involves creating an initial query to one of a set of user terminals (UE1, UE2) e.g. mobile phones, in a telecommunication network i.e. mobile telephone network, where the query contains a header type route. Information for inhibiting initial verification filter criteria is provided to a call session control function (S-CSCF) server. A uniform proxy resource identifier and an address of contact for the user terminal are added after receiving the query. Independent claims are also included for the following: (1) an application server (2) a data signal (3) a call session control function server (4) a computer program comprising instructions for performing a method for establishing an access signaling channel (5) a recording medium with a computer program having instructions for performing a method for establishing an access signaling channel.
