HANDOVER DATA INTEGRITY IN A WIRELESS DATA NETWORK
First Claim
1. A method of operating a handover controller of an access service network of a wireless data network, the method comprising:
- receiving an indication of a data integrity capability of at least one access service network identified as a target access service network for handover of a service flow to mobile terminal;
when the indicated data integrity capability accommodates direct data delivery of data associated with the service flow, initiating direct delivery of the data associated with the service flow from a serving access service network serving the mobile terminal to the target access service network; and
when the indicated data integrity capability does not accommodate direct data delivery of data associated with the service flow, multi-unicasting the data associated with the service flow to the serving access service network and the target access service network.

Abstract
A method and apparatus for handover data integrity of a mobile station in a wireless data network with a plurality of wireless network service areas. The method and apparatus includes initiating handover by a mobile station, identifying a target access service network (ASN) for handover from a serving ASN. When the target ASN is identified, receive a data integrity capability from the target ASN, and determine whether a direct data delivery mode is available as a data integrity mode. When a direct data delivery mode is available, direct data delivery is performed with the data associated with the service flow from the serving ASN to the target ASN.

9. A handover controller of an access service network of a wireless data network, comprising:
-
at least one processor; and at least one memory operably coupled to the at least one processor, the at least one memory storing instructions executable by the at least one processor to; receive an indication of a data integrity capability of at least one access service network identified as a target access service network for handover of a service flow to mobile terminal; initiate direct delivery of the data associated with the service flow from a serving access service network serving the mobile terminal to the target access service network when the indicated data integrity capability accommodates direct data delivery of data associated with the service flow; and multi-unicast the data associated with the service flow to the serving access service network and the target access service network when the indicated data integrity capability does not accommodate direct data delivery of data associated with the service flow. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
