The ITU-T Study Group dealing with mobile telecommunication and fixed mobile convergence together with the lead Study Group on NGN has published a standard that describes what is needed to give users the ability to access the same set of services irrespective of change in location.

Mobility is a crucial part of the service capabilities within the next generation network (NGN) concept. The ITU-T Recommendation notes: “… with the massive growth in the number of users and the continuing deployment of heterogeneous systems the demand to provide seamless services to the NGN users gets stronger…”.

The Recommendation - Q.1706 - describes the requirements for providing ‘mobility management’, that is the set of functions used to provide mobility. These functions include authentication, authorization, location updating, paging and download of user information. The aim of this work is to build on the current mechanisms in cellular telephone systems and the internet and to move toward homogeneity in handling mobility across the converging telecommunication and computing environments.

The next step for SG 19 will be a Recommendation describing the framework for achieving mobility management based on these requirements. SG management suggests that this work is progressing well and will probably be achieved in time for the next round of approvals targeted to be initiated at a meeting in April 2007.

SG 19 also consented a Recommendation that charts further detail in the evolution within the IMT-2000 Family member using an ANSI-41 core network with cdma2000 access network. Recommendation Q.1742.5 references 3GPP2 work.
