A wireless communication system comprises a mobile station in communication with an infrastructure that supports multiple radio frequency (RF) band classes. When the infrastructure receives a request to originate a call from the mobile station via a first radio frequency (RF) band of the multiple RF bands, the infrastructure determines whether to attempt to assign the mobile station to an RF band other than the first RF band. In response to determining to attempt to assign the mobile station to an RF band other than the first RF band, the infrastructure retrieves RF traffic channel decision-related data maintained by the infrastructure before performing further call processing and determines whether the mobile station may be inter-band re-directed based on the RF traffic channel decision-related data. When the mobile station may be inter-band re-directed, the infrastructure re-directs the mobile station to a second RF band of the multiple RF bands.

Method and apparatus for radio frequency band assignment in a wireless communication system

A method of improving hard handoffs in a communication system comprising a source base station (BS), a target BSand a mobile switching center (MSC). In particular, when a handoff is needed, a requested service option and a list of service options supported by a mobile station (MS)are communicated from the source BS to the target BS. Upon receiving a handoff request message, the target base station selects either the requested service option or an alternate service option. The alternate service option is chosen based on one or more of the MS's service option capabilities, service option priorities, and resources available in the target BS. The selected service option is communicated to the source BS and the MS.
