TIA TIA-1154-1

INTRODUCTION AND SCOPE

This document specifies the requirements necessary to support MSC Pool in the CDMA2000^®1 wireless network. MSC Pool enables signaling connections between one BSC with multiple MSCs, so the MS served by any BSC of that pool area can be served by any MSC in that pool area.

The Serving Node Selection Function (SNSF) is the key functionality for the MSC Pool application. The main function of SNSF is selecting a serving MSC within the MSC Pool for a given user, and routing the signaling between the MSC and the BSC.
