Abstract: 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.

Abstract: A method of improving hard handoffs in a communication system comprising a source base station (BS) 114, a target BS 106 and a mobile switching center (MSC) 104. In particular, when a handoff is needed, a requested service option and a list of service options supported by a mobile station (MS) 202 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.

Abstract: A method of hard handoffs begins by establishing a wireless link between a source radio access network (102a) and a mobile station (106). When the mobile station moves into another adjacent radio access network (102b), the present invention detects that handoff of the link from the source to the target is necessary. Additional data is not sent to the mobile station from the source radio access network. The data that has not been received by the mobile station is stored or buffered. A disconnect message is received by the source and a connect message is received by the target so that an active handoff is achieved between the source and the target. When the active handoff procedure is complete the data that was buffered by the source BTS as not being received by the mobile station is then sent to the active target cell such that data and packet loss is reduced.
