1. A method of operating a mobile communications device to implement a handoff of a mobile communications device between a first network attachment point and a second network attachment point, said mobile communications device having a first wireless communications link with the first network attachment point at the time said handoff is initiated, said first wireless communication link using signals in a first frequency band, the method comprising:

  • communicating to said second network attachment point, via a first signal communicated over said first wireless communications link, an intent to initiate a handoff to said second network attachment point;

    receiving, via said first wireless communications link, information indicating a dedicated air link resource assigned to said mobile device by said second network attachment point to be used in communicating with said second network attachment point over a second frequency band which is different from said first frequency band;

    terminating said first wireless communications link; and

    using said dedicated communications resource to transmit a signal over the air in said second frequency band to establish a second wireless communications link with said second network attachment point.
