REDUCING RESOURCE ALLOCATIONS FOR INTER-TECHNOLOGY HANDOVER BETWEEN WIRELESS COMMUNICATION NETWORKS
Disclosed is a method for reducing resource allocations for inter-technology handover between heterogeneous wireless communication networks. The method includes a first step of completing network entry and new session registration procedures for a mobile station with a handover target technology network. A next step includes defining an activity mode of the new session. A next step includes waiting for the expiration of a resource timer at the target network. A next step includes assigning the resources for the new session upon the expiration of the timer.
1 . A method for reducing resource allocations for inter-technology handover between a serving wireless communication network and a target wireless communication network, the serving and target networks of heterogeneous technologies, the method comprising:
completing network entry and session pre-registration procedures for a mobile station with the target network via the serving network and allocating resources by the target network to support pseudo-idle or pseudo-active mode for the mobile station;
entering pseudo-idle mode or pseudo-active mode by the mobile station and continuing to receive service from the serving network;
starting a resource timer at the target network;
upon expiration of the resource timer, initiating inter-technology handover procedures with the mobile station by the target network via the serving network;
deciding by the mobile station whether to accept or reject an inter-technology handover request from the target network;
if the mobile station agrees to accept the inter-technology handover request, then completing inter-technology handover procedures and providing service to the mobile station by the target network;
if the mobile station rejects the inter-technology handover request, then releasing the resources to support pseudo-idle or pseudo-active mode reserved for the mobile station in the target network, wherein service is provided to the mobile station by the serving network; and
leaving pseudo-idle mode or pseudo-active mode by the mobile station.
2 . The method of claim 1 wherein entering pseudo-idle mode comprises:
completing pseudo-idle-mode procedures with the target network via the serving network.
3 . The method of claim 1 wherein completing inter-technology handover procedures comprises:
if the mobile station is in pseudo-idle mode, then completing pseudo-idle-mode handover procedures; and
if the mobile station is in pseudo-active mode, then completing pseudo-active-mode handover procedures.
4 . A method for reducing resource allocations for inter-technology handover between a serving wireless communication network and a target wireless communication network, the serving and target networks of heterogeneous technologies, the method comprising:
completing network entry and session pre-registration procedures for a mobile station with the target network via the serving network and allocating resources by the target network to support pseudo-idle or pseudo-active mode for the mobile station;
entering pseudo-idle mode or pseudo-active mode by the mobile station and continuing to receive service from the serving network;
starting a resource timer at the target network;
upon expiration of the resource timer, sending a release notification message to the mobile station by the target network via the serving network;
releasing the resources to support pseudo-idle or pseudo-active mode reserved for the mobile station in the target network, wherein service is provided to the mobile station by the serving network; and
leaving pseudo-idle mode or pseudo-active mode by the mobile station.
5 . A method for reducing resource allocations for inter-technology handover between a serving wireless communication network and a target wireless communication network, the serving and target networks of heterogeneous technologies, the method comprising:
completing network entry and session pre-registration procedures for a mobile station with the target network via the serving network and allocating resources by the target network to support pseudo-idle or pseudo-active mode for the mobile station;
entering pseudo-idle mode or pseudo-active mode by the mobile station and continuing to receive service from the serving network;
starting a resource timer at the target network;
upon expiration of the resource timer, sending a release notification message to the mobile station by the target network via the serving network;
initiating inter-technology handover procedures with the target network by the mobile station;
completing the mobile-initiated inter-technology handover procedures and providing service to the mobile station by the target network; and
leaving pseudo-idle mode or pseudo-active mode by the mobile station.
6 . A method for reducing resource allocations for inter-technology handover between a serving wireless communication network and a target wireless communication network, the serving and target networks of heterogeneous technologies, the method comprising:
completing network entry and session pre-registration procedures for a mobile station with the target network via the serving network and allocating resources by the target network to support pseudo-active mode for the mobile station;
entering pseudo-active mode by the mobile station and continuing to receive service from the serving network;
starting a resource timer at the target network;
upon expiration of the resource timer, completing pseudo-idle-mode entry procedures with the mobile station via the serving network;
entering pseudo-idle mode by the mobile station; and
releasing the resources to support pseudo-active mode reserved for the mobile station in the target network, wherein service is provided to the mobile station by the serving network.
