Abstract: The present invention provides a method for supporting handoffs of a first mobile unit in a wireless communication system that supports multiple vocoder technologies. The method includes allocating, prior to completion of a handoff of the first mobile unit, a transcoder function to the first mobile unit. The method also includes detecting a change in a format of at least one packet received from the first mobile unit. The change indicates that the vocoder technology used by the first mobile unit to form packets has changed. The method also includes transcoding packets in response to detecting the change in the format.

Abstract: A broadband address of a first subscriber is identified and communicated to a second subscriber in a first communication system using an SMS data enabled cellular system or call origination set up messaging. If authorization is given by the second subscriber, the broadband address of the second subscriber is delivered to the first subscriber by the first communication system, whereby the first and second subscribers have exchanged their respective broadband addresses over a first communications system where the broadband addresses are utilized for broadband communications over a second communication system.

Abstract: The present invention provides a method and apparatus for re-sequencing data packets received from multiple devices in a packet-based digital communication system. A set of data packets is received by a data packet sequencer. Each data packet includes an indicator of the originator of the data packet. The data packet sequencer stores the set of data packets, preferably in an input buffer. The data packet sequencer reorders the data packets by retrieving a first data packet and determining the originator of the first data packet. The data packet sequencer then transmits all data packets that were originated by a first originator of the first data packet prior to transmitting data packets that were not originated by the first originator.

Abstract: The present invention provides a method and apparatus to allow network-initiated information delivery based on the delivery priority of the information and the available over-the-air resources. Originators of the information to be delivered specify the delivery priority of the information. The network monitors the utilization of the over-the-air interface and delivers the information when the utilization is appropriate given the assigned delivery priority of the information.

Abstract: An improved wireless network provides intersystem handoffs between existing circuit wireless systems and packet systems. A packet wireless system is enhanced to provide translation between circuit and packet call models. A Media Gateway translates bearer traffic between formats used in each system. The Media Gateway, a Media Gateway Control Function, and an associated Call State Control Function, cooperate to emulate the behavior of a circuit wireless system, so that when interoperating with conventional circuit systems, the packet system appears to be another circuit wireless system. Where necessary, the Media Gateway, Media Gateway Control Function, and Call State Control Function further cooperate to emulate the functions of an anchor MSC of a circuit wireless system.
