Method and device for determining MME pool

Abstract

The invention discloses a method and a device for determining an MME pool, and relates to the technical field of communication. The method comprises the steps of counting the switching frequency of aterminal between adjacent administrative regions; determining an administrative region belonging to the MME pool according to the switching frequency and based on a preset division rule; and forming the MME pool by all MMEs in the administrative region belonging to the MME pool. According to the invention, by adopting the method and the device for determining the MME pool, the user mobility is determined on the basis of the counted cross-regional switching frequency. Meanwhile, a regional boundary with smaller user mobility is taken as the boundary of the MME pool division. Moreover, the division result of the MME pool is adjusted based on the volume of service, so that the number of users and the number of base stations in the MME pool are balanced. The TAU process caused by the handoverof the MME pool can be effectively reduced. The impact of the TAU process signaling message on a core network is reduced. Meanwhile, the balanced distribution of the service is realized.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for determining an MME POOL. Background technique [0002] On December 4, 2013, the Ministry of Industry and Information Technology issued TD-LTE licenses to China Mobile, China Telecom and China Unicom, and China's wireless communications have officially entered the 4G commercial era. On June 27, 2014, the Ministry of Industry and Information Technology issued FDD-LTE licenses to China Telecom and China Unicom, and approved 16 China Telecom FDD-LTE trial commercial cities including Nanjing. So far, China Telecom has officially launched 4G For mobile terminals and packages, China Telecom has started a new era of large-scale promotion of 4G commercial use. In April 2016, after nearly three years of business development, the current number of concurrent users of Jiangsu Telecom has reached 6 million, and the scale of base stations has reach...

AI Technical Summary

Problems solved by technology

At present, there are no good principles and guiding methods for the division of MME POOL. If the MME POOL is not well divided, there will be more TAU processes across MMEs. The TAU process will generate a large number of Diameter signaling messages on the core network. The impact of the network is very large, and this situation has already appeared in the expansion of some key provinces
