Abstract
Techniques for packet core network (PCN) gateway selection of collocated gateways are disclosed herein. A mobility management entity (MME) can retrieve charging characteristics (CC) information to determine whether collocated gateway selection is applicable for a UE. When collocated gateways are to be selected, the MME can configure domain name server (DNS) queries in a manner which is adapted for collocated gateway identification. Upon receipt of the DNS query, the DNS can be configured to identify collocated serving gateways (SGWs) which are each collocated with a packet gateway (PGW). The DNS can return identifications of the collocated SGWs to the MME, and the MME can use the identifications of the collocated SGWs to select a collocated SGW and a corresponding collocated PGW for use in connection with the network access for the user equipment.
