ESTABLISHING A DIRECT COMMUNICATION (T5 ASSOCIATION)BETWEEN A MOBILITY MANAGEMENT ENTITY (MME) AND A MACHINE TYPE COMMUNICATION INTERWORKING FUNCTION (MTC-IWF)

摘要

Example embodiments presented herein are directed towards providing direct communications between a mobility management node (e.g., SGSN, S4-SGSN or MME) and an MTC-IWF node via a T5 interface. With the use of the direct communications unnecessary queries to a HSS or HLR may be avoided. The direct communications are established by the mobility management node and the MTC-IWF node saving identifying information of the other node.
