A wireless communication network, such as a 1xEV-DV network, manages concurrent services handoff to force re-registration of concurrent-services capable mobile stations that have undergone hard handoff during an active voice call. During such handoffs, the mobile station moves from a source base station to a target base station, each supporting concurrent services, and with each base station having associated network identification parameters. In response to receiving the mobile station in hard handoff while it is engaged in an active voice call, the target base station sends one or more of these network identification parameters as dummy values, which results in re-registration of the mobile station on the voice side of the network. The target base station broadcasts actual network identification parameters on one or more overhead channels such that the mobile stations operating in its coverage area have access to true network identification parameters.
In a wireless communication network, a method of performing a hard handoff of a mobile station that supports concurrent voice and data services, comprising:
A base station supporting concurrent circuit-switched and packet-switched services for use in a wireless communication network, the base station operative to:
A mobile switching center (MSC) supporting concurrent circuit-switched and packet-switched services for use in a wireless communication network, the MSC operative to:
