摘要

Location of the mobile user is registered to the two databases for call tracking and those registration processes basis much network traffic. By this speed of Call delivery reduced and location updating cost improved. In this paper, the first method a new meek location management by registering Representative VLR of group of certain VLRs regionally and broadcasting for searching a mobile user, so called rVLR-B.This The representative VLR of several VLRs and register mobile users' location. When set up the call path between mobile users, the VLR of the caller inquiries callee's rVLR for searching the location of callee instead of demanding to VLR of callee. And then rVLR broadcast the callee's location to all VLR of the region simultaneously. Location registration is only performed when a mobile user visits a new rVLR network area from present area. Using the rVLR-B, the cost of maintaining location of mobile users was abridged. The second technique for reducing the costs during the location tracking and location update is proposed. Taking the regular movement pattern of the users it produces the block and the user registers with the HLR only after crossing the block instead of crossing the single cell. The block register (BR) is introduced between the block and the HLR in two level systems to preserve the blocks, thus creates three level architecture. In this architecture some signaling cost values between the MSC-BR, BRHLR and BR-BR are maintained to get the better enactment. By the rVLR-B and BR the performance of speed of call delivery improved and location updation will be diminished.
