METHODS AND DEVICES FOR CONTINUATION OF TERMINATING SERVICES IN IMS COMMUNICATION NETWORKS

摘要

A method implemented by a first network node in an IMS communication network is provided. The method may comprise: receiving a register request from a user equipment; and transmitting the register request which comprises contact information of the user equipment to a second network node. In the present disclosure, the P-CSCF may be able to route the terminating requests without UE registration bindings, which increases a successful rate of the terminating services.
