Dynamic gateway selection based on the roaming protocol and data services

摘要

Techniques for supporting roaming in wireless communication networks is described. The preferred roaming protocol and APN for the UE is roaming in the visited network from the home network in one design can be obtained. The APN may be associated with a data service requested by the UE. May GTP, MIP, etc. PMIP preferred roaming protocol. Appropriate network entity providing data connectivity for the UE may be determined based on the roaming protocols and preferred APN. May be a PDN gateway in the home network (i) preferred roaming protocol if a GTP network entity, and it may be a home agent in the home network (ii) preferred roaming protocol if a MIP or PMIP In one design .
