Study On The Optimization Of UATI Distribution Siccess Rate

Unique terminal access identifier UATI, Full name is Unicast Access Terminal Identifier. Similar to the home LAN IP address inside, Terminal for identifying an access network. Because at the same time, Network can be linked to multiple terminals, And in order to distinguish these terminals, For the terminal refers to the end of the match with the UATT address ID.UATI allocation success rate is characterized by AT application to AN UATI success probability, This index is related to the factors such as network load, AN performance and quality of wireless network.UATI allocation success rate affects user perception.At present, wireless network optimization has not formed a set of practical and feasible operation standard and process of the system.In this paper, we try to start with the principle of 3G network environment,from a more intuitive and easier to understand the wireless environment,analysis of the reasons for the failure of UATI distribution and optimization of UATI allocation success rate. First of all, the concept of UATI is described in this paper. Next, the signaling flow of UATI distribution is given. And then analyze the reasons for the failure of UATI distribution. On the basis of this analysis, the optimization method of UATI distribution success ratio is analyze The purpose is to form a set of practical and feasible operation rules and procedures to guide the optimization of UATI distribution success rate.
