Problems solved by technology

In the mobile IP telephone network, various services related to mobile IP can be completely transparent to the access network like the general packet radio service (GPRS) of the lower layer, so that the access network cannot communicate with the mobile IP telephone core. Network provides any location information

[0023] Figure 3 shows the establishment of location-based routing to a special service number using the H.323 environment. According to the first embodiment of the present invention, location information of a user is provided to the mobile IP telephone core network in the following manner. In Fig. 3, the IP terminal IPTE requests permission from the call state control function block (CSCF) through a normal H.323 process. More precisely, in message 1, the user IPTE issues an admission request (ARQ) with the requested bandwidth to the CSCF in which the IPTE is currently registered. In message 2, since the CSCF routing call model is to be used, if the CSCF can accept the call, it returns an admission confirmation (ACF) signal with its own H.225.0 call signaling transport address (TA).

[0024] The application knows that it must obtain IPTE location information for this call. The location information is obtained from the mobile terminal MT through the interface between the mobil...

Abstract

This invention discloses a system and a method used in using the position information of an IP terminal to select routes in mobile IP phone network, when sending a call from an IP terminal to another user, the method detects if the position information of the IP terminal is needed by the call, if so, the position information is added into call data, then a target address is determined based on the call data and the position information, and finally, the call is sent to the determined target address.

Description

[0001] This application is a divisional application of a patent application with application number 99817029.1, date of application is December 7, 1999, and title of invention is "Method and System for Call Routing Selection Based on Caller's Location in Mobile IP Network". technical field [0002] The present invention relates to the utilization of user location information in mobile Internet Protocol (IP) telephony networks. In particular, the present invention relates to a method and system for call routing selection using location information of an IP terminal in a mobile IP telephone network. Background technique [0003] In a conventional mobile circuit-switched network like the Global System for Mobile communications (GSM), the location information of a mobile station is revealed to the network by a Base Station System (BSS). In the mobile IP telephone network, various services related to mobile IP can be completely transparent to the access network like the general p...
