3GPP has investigated and documented various aspects of interworking as well as transition mechanisms related to IPv6 address usage and coexistence with IPv4 environment. These guidelines are as well applicable for usage in environment like MTC as deemed appropriate.

– For general guidelines towards IPv6 migration aspects, TR 23.975 [36], "IPv6 migration Guidelines" should be followed as appropriate.

– For Session based applications similar to IMS, TR 23.981 [26], "Interworking aspects and migration scenarios for IPv4-based IP Multimedia Subsystem (IMS) implementations" may be used as appropriate. The report describes baseline guidelines and in conjunction with TS 23.228 [11] provides comprehensive details for coexistence/transition/migration for IPv6 and IPv4 addressing in 3GPP networks for IMS.
