Method of implementing UE capability exchange and route control for parallel IMS and CS services
First Claim
1. A method of using an equipment identity (ID) in an IP Multimedia Subsystem (IMS) network, comprising:
- receiving an equipment ID, a service ID, and capability information of a first User Equipment (UE), sent from the first UE, by a second UE; and
storing, by the second UE, the service ID, the capability information, and equipment ID of the first UE, as well as a correlation among the service ID, the capability information, and the equipment ID of the first UE,wherein the equipment ID uniquely identifies a UE among multiple UEs sharing a same IP multimedia public user identity (IMPU) in the network.

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.

14. A method of implementing route control for parallel IP Multimedia Subsystems (IMS) and Circuit Switched (CS) services in a communication system, comprising the following steps:
-
A) sending, by a first User Equipment (UE), a service request containing an equipment ID of a second UE; B) utilizing, by a service control function entity in a network, the equipment ID of the second UE contained in the service request to look up an established correlation among equipment ID, service ID, and UE address of UEs, and obtaining a contact address of the second UE; C) forwarding, by the service control function entity, the service request to the second UE in accordance with the contact address of the second UE. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for capability information exchange between User Equipments (UEs) in an IP Multimedia Subsystem (IMS) network, comprising:
-
receiving an equipment identity (equipment ID), capability information, and a service ID of a first UE, which are sent from the first UE, by a second UE; storing, by the second UE, the capability information, the equipment ID, and the service ID of the first UE as well as a correlation among the service ID, the capability information, and the equipment ID of the first UE; matching, by the second UE, an equipment ID and a service ID contained in a subsequently received service request or response to service request with the locally stored equipment ID and the service ID; and initiating, by the second UE, a capability information exchange with a UE which sends the subsequently received service request or response to service request, if the equipment ID and service ID contained in the subsequently received service request or response to service request does not match the locally stored equipment ID and the service ID, in which the equipment ID identifies a UE among multiple UEs sharing a same IP multimedia public identity (IMPU). - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A user equipment (UE), comprising:
-
means for receiving an equipment identity (equipment ID), capability information, and a service ID of a remote UE; means for storing the equipment ID, the capability information, and the service ID of the remote UE as well as a correlation among the equipment ID, the capability information, and the service ID of the remote UE; means for matching an equipment ID and a service ID contained in a subsequently received service request or response to service request with the locally stored equipment ID and the service ID; and means for initiating a capability information exchange with a UE which sends the subsequently received service request or response to service request, if the equipment ID and service ID contained in the subsequently received service request or response to service request does not match the locally stored equipment ID and the service ID. - View Dependent Claims (41, 42, 43, 44)
