The purpose of this TR is to help the relevant 3GPP groups to specify the changes to existing specifications, needed for the introduction of the "Handover for real-time services from PS domain" Building Block for Release 2000.
The purpose of this R00 work task is to define the relocation procedure to be used when real time services are supported in the PS domain.
The intention with this work item is to provide support for services such as voice over IP and multimedia over IP.
This TR focuses on the requirements for the solution. Possible solutions have been further studied and they are also described in this TR for comparison and evaluation against the requirements. In doing this work, RAN3 has identified some areas of study that are not primarily under RAN3's responsibility. These are mentioned here so that work can be coordinated with the other 3GPP groups.
Changes to the signalling protocols in UTRAN and CN interfaces have also been studied at a high level.
