An embodiment of a method for communicating call control signaling information in a communications system that includes a user equipment (UE) and a base includes the UE formatting the call control signaling information, transmitting the call control signaling information over a first logical channel
An embodiment of a method for communicating call control signaling information in a communications system that includes a user equipment (UE) and a base includes the UE formatting the call control signaling information, transmitting the call control signaling information over a first logical channel that is mapped to a first transport channel, and transmitting user traffic over a second logical channel that is mapped to a second transport channel. In an embodiment, the base receives the call control signaling information from the UE over the first logical channel, receives the user traffic from the UE over the second logical channel, and transmits the call control signaling information to a core network. In an embodiment, the communication system is an IP network in which information is exchanged between the UE and the base using a W-CDMA transmission protocol. The base may form a portion of a satellite-based radio network.

1. A method for communicating call control signaling information in a wireless communications system that includes a core network, a user equipment (UE) and a base in a radio network, the method comprising the steps of: formatting the call control signaling information;transmitting the call control signaling information from the UE to the base over a first logical channel that is mapped to a first transport channel;transmitting user traffic from the UE to the base over a second logical channel that is mapped to a second transport channel; andcommunicating from the base the call control signaling information and the user traffic received from the UE to the core network over an Iu interface of an Iu user plane rather than over an Iu control plane. 2. The method of claim 1, wherein formatting the call control signaling information comprises formatting the call control signaling information into a message according to a Session Initiation Protocol (SIP). 3. The method of claim 1, wherein formatting the call control signaling information comprises formatting the call control signaling information as a message according to a protocol within a group of protocols consisting of a Session Initiation Protocol (SIP) and H.323. 4. The method of claim 1, wherein transmitting the call control signaling information and transmitting the user traffic comprises transmitting the call control signaling information and transmitting the user traffic using a Wideband Code Division Multiple Access (W-CDMA) transmission protocol. 5. The method of claim 1, further comprising: multiplexing additional control information allocated to one or more other logical channels with the call control signaling information prior to transmitting the call control signaling information. 6. The method of claim 5, wherein the additional control information includes information selected from a group consisting of access stratum control information and non-access stratum control information. 7. The method of claim 6, wherein at least a third logical channel is allocated to the access stratum control information, and at least a fourth logical channel is allocated to the non-access stratum control information. 8. The method of claim 1, further comprising: receiving call control signaling information destined for the UE from the base over the first logical channel that is mapped to the first transport channel. 9. The method of claim 1, further comprising: before communicating the call control signaling information or the user traffic to the core network:multiplexing, at the base, the call control signaling information with other call control signaling information from other UEs to generate multiplexed call control signaling information for communication over the Iu interface to the core network in the Iu user plane; andmultiplexing, at the base, the user traffic with other user traffic from other UEs to generate multiplexed user traffic for communication over the Iu interface to the core network in the Iu user plane. 10. A method for communicating call control signaling information in a wireless communications system that includes a core network, a user equipment (UE) and a base in a radio network, the method performed by the base and comprising the steps of: receiving the call control signaling information from the UE over a first logical channel that is mapped to a first transport channel;receiving user traffic from the UE over a second logical channel that is mapped to a second transport channel; andtransmitting from the base the call control signaling information and the user traffic received from the UE to the core network over an Iu interface of an Iu user plane rather than over an Iu control plane. 11. The method of claim 10, wherein receiving the call control signaling information comprises: receiving multiplexed control information from the UE over the first transport channel; andde-multiplexing the multiplexed control information to produce the call control signaling information and additional control signaling information. 12. The method of claim 11, wherein the additional control information includes information selected from a group consisting of access stratum control information and non-access stratum control information. 13. The method of claim 10, further comprising: receiving additional call control signaling information from one or more other UE; andmultiplexing the call control signaling information with the additional call control signaling information to produce multiplexed call control signaling information, wherein transmitting the call control signaling information comprises transmitting the multiplexed call control signaling information over the Iu interface of the Iu user plane. 14. The method of claim 10, further comprising: receiving multiplexed call control signaling information from the core network;de-multiplexing the multiplexed call control signaling information to produce call control signaling information destined for the UE; andtransmitting the call control signaling information destined for the UE to the UE. 15. The method of claim 10, further comprising: before communicating the call control signaling information or the user traffic to the core network:receiving additional user traffic from other UEs; andmultiplexing, at the base, the user traffic with additional user traffic from other UEs to produce multiplexed user traffic for communication to the core network over the Iu interface. 16. A wireless communications system comprising: a core network;a base in a radio network that is communicatively coupled to the core network over an Iu interface of an Iu user plane; anda user equipment (UE) configured to format call control signaling information, transmit the call control signaling information to a base over a first logical channel that is mapped to a first transport channel, and transmit user traffic over a second logical channel that is mapped to a second transport channel, andwherein the base is configured to receive the call control signaling information from the UE over the first logical channel, receive the user traffic from the UE over the second logical channel, and transmit the call control signaling information and the user traffic received from the UE to the core network over the Iu interface of an Iu user plane rather than over an Iu control plane. 17. The communications system of claim 16, wherein information is exchanged between the UE and the base using a Wideband Code Division Multiple Access (W-CDMA) transmission protocol. 18. The communications system of claim 16, wherein the UE is a wireless communication device selected from a group of devices comprising a cellular telephone, a radio, a pager, a personal data assistant, a computer, a network transceiver, an unmanned autonomous vehicle, and a wireless transceiver. 19. The communications system of claim 16, wherein the base forms a portion of a satellite-based radio network. 20. The communications system of claim 16, wherein the base is configured to multiplex the call control signaling information, before communicating the call control signaling information to the core network, with other call control signaling information from other UEs to generate multiplexed call control signaling information for communication over the Iu interface to the core network in the Iu user plane; and wherein the base is configured to multiplex the user traffic, before communicating the user traffic to the core network, with other user traffic from other UEs to generate multiplexed user traffic for communication over the Iu interface to the core network. 21.
