Handover data integrity in a wireless data network
First Claim
1. A method for handover data integrity of a mobile station in a wireless data network, the method comprises:
- identifying at least one target access network (ASN) for handover from a serving ASN that services wireless data communications with the mobile station;
receiving a data integrity capability from the at least one target ASN;
determining whether a direct data delivery mode is available as a data integrity mode based upon the data integrity capability;
when the direct data delivery mode is available as the data integrity mode, performing direct data delivery of data associated with a service flow from the serving ASN to the at least one target ASN; and
performing a handover of the mobile station to a target ASN of the at least one target ASN to service the wireless data communications of the mobile station.

Abstract
Provided is 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 initiation of a handover by a mobile station, identifying at least one target access network (ASN) for handover from a serving ASN that services wireless data communications with the mobile station. When at least one target ASN is identified, receiving a data integrity capability from the at least one target ASN. With the received data integrity capability, determining whether a direct data delivery mode is available as a data integrity mode based upon the received data integrity capability. When the direct data delivery mode is available as a data integrity mode, direct data delivery if performed with the data associated with the service flow from the serving ASN to the at least one target ASN. When the direct data delivery is accomplished, the mobile station handover is completed from the serving ASN to one of the target ASNs.

7. A method for handover data integrity of a mobile station in a wireless data network, the method comprising:
-
identifying at least one target access network (ASN) for handover from a serving ASN servicing wireless data communications with the mobile station; negotiating, via an anchor ASN, a data integrity mode of a plurality of data integrity modes based upon a data integrity capability provided by the at least one target ASN; when the data integrity capability provided by the at least one target ASN accommodates a first data integrity mode of the plurality of data integrity modes, multi-unicasting data associated with a service flow via the anchor ASN to the serving ASN and the at least one target ASN; when the data integrity capability provided by the at least one target ASN accommodates a second data integrity mode of the plurality of data integrity modes, performing direct data delivery of the data associated with the service flow from the serving ASN to the at least one target ASN; and performing the handover of the mobile station to a target ASN of the at least one target ASN, wherein the target ASN of the at least one target ASN begins servicing the wireless data communications with the mobile station. - View Dependent Claims (8, 9, 10, 11, 12)

13. Apparatus for an anchor access network (ASN) to provide handover data integrity in a wireless data network, the apparatus comprising:
-
processing module; and memory operably coupled to the processing module, wherein the memory stores operational instructions that cause the processing module to; identify at least one target ASN for handover from a serving ASN that services wireless data communications with a mobile station; negotiate with the at least one target ASN a data integrity mode of a plurality of data integrity modes based upon a data integrity capability provided by the at least one target ASN; when the data integrity capability provided by the at least one target ASN accommodates a first data integrity mode of the plurality of data integrity modes, multi-unicast data associated with a service flow via the anchor ASN data to the serving ASN and to the at least one target ASN; when the data integrity capability provided by the at least one target ASN accommodates a second data integrity mode of the plurality of data integrity modes, initiate direct delivery of the data associated with the service flow from the serving ASN to the at least one target ASN; and perform the handover of the mobile station to a target ASN of the at least one target ASN, wherein the target ASN of the at least one target ASN begins servicing the wireless data communications with the mobile station. - View Dependent Claims (14, 15, 16, 17, 18)
