CDMA and PRMA Analytical Models for Voice Users in Satellite-UMTS SystemsMultiple Access (TD-CDMA) for TDD mode. In this article two MAC (Medium Access Control) protocols are compared analytically and by simulation for LEO (Low Earth Orbit) satellite used in UMTS. The goal of this comparison is to choose the protocol that benefits from efficient statistical multiplexing on the large common pool of available resources.

Using SIP Extensions for Signalling in Stream Service Systemattention is paid to the use of SIP and SIP extensions with XML content for managing the parameter negotiations. Resource reservation is also made possible to the service control system by making use of the bandwidth broker of the network service provider.
