METHOD AND SERVER FOR DETERMINING ASSOCIATIONS BETWEEN POOLS OF CORE NETWORK NODES AND BASE STATIONS

摘要

The present invention relates to positioning in a communication network. In Long Term Evolution, LTE networks the positioning server E-SLMC needs routing information in order to communicate with individual base stations, eNodeBs. For LTE networks configured with one Mobility Management Entity, MME or one pool of MMEs, the routing information can be obtained by interrogating the MME or an arbitrary MME in the MME pool. However, if the network is configured with several MME pools serving different sets of eNodeBs, the E-SLMC has now knowledge of which MME or MME pool that is serving a certain eNodeB. The invention includes a method and a position server (111) configured to quickly determine which MME pool (120,130) is serving a certain eNodeB (141-153) so that the relevant routing information necessary for the positioning server (111) to communicate with the eNodeBs (141-153) is obtained.
