Method of implementing UE capability exchange and route control for parallel IMS and CS services
First Claim
1. A method comprising:
- receiving, by a second User Equipment (UE), an equipment ID of a first UE and capability information of the first UE, sent from the first UE;
storing, by the second UE, the equipment ID of the first UE and the capability information of the first UE, along with a correlation between the equipment ID and the capability information;
wherein the equipment ID uniquely identifies the first UE among multiple UEs sharing a same IP multimedia public user identity (IMPU), and wherein the equipment ID and the capability information of the first UE are used for establishing an IP multimedia subsystem (IMS) session and a Circuit Switched (CS) call in the CS Bearers with IP Multimedia Subsystem (CSI) service;
receiving, by the second UE, a message including a received equipment ID;
judging, by the second UE, whether the capability information corresponding to the received equipment ID included in the message is stored locally in the second UE; and
performing, by the second UE, service handling in accordance with the result of the judging, with the performing the service handling comprising initiating, by the second UE, a capability exchange if the capability information corresponding to the received equipment ID included in the message is not stored locally in the second UE, or initiating, by the second UE, a CSI related operation in subsequent interaction in accordance with the capability information corresponding to the received equipment ID included in the message, if the capability information corresponding to the received equipment ID included in the message is stored locally in the second UE.

Abstract
The present invention discloses a method of implementing UE capability exchange and a method of route control for parallel IMS and CS services in communication system, so as to distinguish among multiple UEs sharing a same IMPU during capability exchange and route control. Said method comprises: each of UEs involved in capability exchange sending its capability information to the opposite party respectively; the opposite party storing these information as well as the correlation between the information and the service ID; The UE including equipment ID of the opposite UE in an initiated service request; service control function entity in the network utilizing the equipment ID to query the established correlation among equipment ID, service ID, and address of the UE, so as to determine the address of the destination UE and route the service request to the destination UE. Said equipment ID identifies effectively a UE in the network.
