5.1 Service Interworking

Service interworking is required when the Teleservice at the calling and called terminals are different. No service interworking is specified in this specification.

5.2 Network Interworking

Network interworking is required whenever a PLMN is involved in communications with another network to provide end-to-end communications. The PLMN shall interconnect in a manner consistent with that of a normal Data Network (type defined by the requirements e.g. IP). Interworking appears exactly like that of Data Networks.
