Abstract:

With the large-scale commercial disposition of TD-SCDMA network,the inter-working and handover of between TD-SCDMA and GSM will be occurred more and more.To improve effectively handover success rate between TD-SCDMA and GSM is very important for TD-SCDMA network construction and optimization.This paper focus on the handover failure problem based on authentication in TD-SCDMA and GSM systems inter-working presently,gives the reason of handover failure by analyzing the handover failure phenomenon and 3GPP technical specification,bring forwards a solution for this question.At last,the authors realize the patch program acting on the solution and test it in existing network,the testing result proves that the solution proposed in this paper is feasible.

Key words: TD-SCDMA, GSM, inter-working, solution
