Patent ID: 8311010

Claim:
A method for providing data integrity in a wireless communication network, comprising: providing a quality of service (QoS) profile for a service flow, the QoS profile including information of one or more QoS requirements of the service flow and a data integrity indicator to indicate information of data integrity for the service flow; indicating whether to use a remote data integrity policy or a local data integrity policy; negotiating, using the indicated data integrity policy indicator, a data integrity scheme from one or more data integrity schemes available to the service flow during a handover of a mobile station from one base station to another base station; operating an anchor data path function for the mobile station in the wireless network to collect data integrity information from data path functions in network entities related to the service flow for the mobile station; selecting the data integrity scheme for each network entity that carries the service flow for the mobile station; using a message for each of the related network entities to include a data integrity time-length-value field to include the data integrity capability information for each network entity to communicate the data integrity capability information to the anchor data path function for the mobile station; and operating the anchor data path function to send a data integrity command message that includes the selected data integrity scheme to each of the related network entities.
