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.
In a wireless communication system comprising a mobile station in communication with an infrastructure that supports a plurality of radio frequency (RF) bands, a method for assigning an RF band to the mobile station when the mobile station is engaged in a process of originating a call via the infrastructure, the method comprising:
An apparatus for assigning a radio frequency (RF) band to a mobile station when the mobile station is engaged in a process of initiating a connection with an infrastructure, the apparatus comprising a base station that receives call origination request from the mobile station via a first radio frequency (RF) band, in response to receiving the call origination request, determines whether to attempt to assign the mobile station to an RF band other than the first RF band, in response to determining to assign the mobile station to an RF band other than the first RF band, requests only infrastructure-maintained RF traffic channel decision-related data associated with the mobile station, in response to the request, receives only the infrastructure-maintained RF traffic channel decision-related data while not receiving other information stored in the profile of the mobile station, determines whether the mobile station is to be inter-band re-directed based on the RF traffic channel decision-related data, and in response to determining that the mobile station is to be inter-band re-directed, instructs the mobile station to switch to the second RF band before performing any other call processing.
A call controller that receives a service request, determines that the service request includes a request for infrastructure-maintained radio frequency traffic channel decision-related data associated with a mobile station, and in response to determining that the service request includes a request for infrastructure-maintained radio frequency traffic channel decision-related data, retrieves only a portion of the profile of the mobile station, wherein the portion comprises the radio frequency traffic channel decision-related data associated with the mobile station, and conveys only the retrieved radio frequency traffic channel decision-related data to the base station before performing further call processing.
