METHOD AND APPARATUS APPLIED TO IDENTIFICATION FOR HANDOVER BETWEEN WIRELESS COMMUNICATION NETWORKS
First Claim
1. A method to be executed in a first UE (User Equipment), applied to identification for handover from a current serving network to a target network, comprising the steps of:
- (a) acquiring handover status information for a second UE communicating with the first UE; and
(b) sending identity confirmation information to the second UE according to the handover status information so as to the second UE validates the first UE'"'"'s identity, wherein different networks are employed at step (a) and step (b).

Abstract
The invention provides a method and apparatus to be executed in a first UE (User Equipment), applied to identification for handover from a current serving network to a target network, the method comprising the steps of: acquiring handover status information for a second UE communicating with it; and sending identity confirmation information to the second UE according to the handover status information so that the second UE can validate its identity, wherein the handover status information and the identity confirmation information are transmitted via different networks. With the proposed method and apparatus, the handover procedure between two wireless networks can be facilitated even in the case of not providing identification information of the calling party of the handover call.

10. A method to be executed in a second UE, applied to identification for handover from a current serving network to a target network, comprising the steps of:
-
(a) exchanging information with a first UE in communication with the second UE so as to the first UE acquires handover status information for the second UE; and (b) receiving identity confirmation information from the first UE, so as to validate the identity of the first UE, wherein different networks are employed at step (a) and step (b). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A first UE capable of performing handover between networks, comprising:
-
a current serving network interface, for communicating with a second UE via a current serving network; a target network interface, for sending a handover call to the second UE via a target network to be transferred to, and for communicating with the second UE after handover to the target network; a sending unit, for sending information to the second UE via the current serving network interface or the target network interface, to request the second UE to accept the handover call; a receiving unit, for acquiring handover status information for the second UE communicating with it via the current serving network interface or the target network interface; and a detecting unit, for detecting the handover status information received by the receiving unit for indicating whether the second UE permits handover; wherein the sending unit sends identity confirmation information to the second UE via the current serving network interface or the target network interface according to the detection result of the detecting unit, so that the second UE validates its identity; and wherein the handover status information and the identity confirmation information are transmitted respectively via different network interfaces. - View Dependent Claims (20, 21, 22, 23, 24)

25. A second UE capable of performing handover between networks, comprising:
-
a current serving network interface, for communicating with a first UE via a current serving network; a target network interface, for receiving a handover call from the first UE via the target network to be transferred to and for communicating with the first UE after transferring to the target network; a receiving unit, for receiving handover call request information from the first UE via the current serving network interface or the target network interface; a determining unit, for determining whether handover is permitted according to the handover call request information received by the receiving unit; and a sending unit, for sending handover status information to the first UE via the current serving network interface or the target network interface according to the determination result of the determining unit; wherein the receiving unit receives identity confirmation information from the first UE via the current serving network interface or the target network interface, to validate the identity of the first UE; and wherein the handover status information and the identity confirmation information are transmitted via different network interfaces respectively. - View Dependent Claims (26, 27, 28, 29)
