Title: A Migration Path from GSM to GSM/GPRS
Author: Abdalla Mohamednur, Mohamednur
Abstract: The General Packet Radio service (GPRS) is a new non-voice (data) value added service that allows information to be sent and received across a mobile telephone networks. GPRS has evolved to cater to the mobile users by enabling them to access the internet world incessantly. It will provide a massive boost to mobile data communication. The aim of this thesis is to setup a migration path from GSM to GSM/GPRS service (2.5G). The focus is on real world migration plan that can be implemented on the existing infrastructure of MobiTel-Sudan network. The plan can be implemented into three phases, phase1 is to implement the GPRS in the center of Khartoum in which we focus, phase 2 in centre of Khartoum north and Omdurman, phase three is in the rest of Sudan. The plan takes into considerations economical factors as well as technical aspects. The migration path from GSM to GPRS requires additional packet switching nodes, software upgrade in the base station subsystem (BSS) and Core network. In phase1 we choose BSC3, BSC6 and MSC3/VLR3 which cover the center of Khartoum and located in Dar Elhatif to be connected with the SGSN and GGSN. As the mobility management plays a significant role in the GPRS such as routing area updates we suppose that BSC3&6 connected with SGSN will be in two routing area in Phase1 to avoid inter SGSN routing area updates, however in the following phases different forms of user mobility and their effects on the communication traffic can be will planned. The traffic in Erlang and hardware has been calculated from the traffic and hardware dimension reports of the network to accommodate the GPRS in these nodes. We use Ericsson SGSN, GGSN, and their specifications to be implemented in this phase In addition to access server and firewalls.
