IS-41 GSM Migration
Overview
The need to provide 3G services and standardize networks to achieve efficiencies is driving many mobile operators worldwide to make the shift to global system for mobile communication (GSM) technology. Various factors are contributing to this trend, with mergers, acquisitions and roaming partnerships playing a large role. GSM technology also provides an evolution path to 3G networks and the delivery of new next-generation wireless voice and data services.
In addition to changing the radio access network from time division multiple access (TDMA) or code division multiple access (CDMA), operators will have to migrate the signaling network from IS-41 to GSM. As subscribers are transferred to the new GSM-based network, mobile operators require a flexible solution to manage the required changes in home location register (HLR) routing.
It is important for this transition phase to be transparent to the customer. Allowing subscribers to retain their existing mobile phone number will be key to this process. Also, dual or single technology handsets and SMS messaging must be supported.
