Abstract
A gateway serving as an interface between a mobile network and a wireless network can be configured to send a signal strength indicator to the mobile network thereby causing the mobile network to recognize the gateway as a valid path for handing off a call. The wireless network can be configured according to one of the 802.11 wireless communications protocols. The gateway can route the call from the mobile network to a wireless access point of the wireless network via a packet-switched network, such that the call is conducted via a wireless communications link with the wireless access point.
Claims14
A gateway serving as an interface between a mobile network and a wireless network, wherein said gateway is configured to send a signal strength indicator to the mobile network thereby causing the mobile network to recognize the gateway as a valid path for handing off a call.
A system for call control between a mobile network and a wireless network comprising:
- means for establishing, with a mobile network, a control messaging link for exchanging control signal channel signaling data and a voice channel link for exchanging audio data for a mobile call;
- means for sending a signal strength indicator to the mobile network thereby causing the mobile network to recognize the system as a valid path for handing off the mobile call;
- means for establishing a communications link with a packet-switched network;
- and
- means for routing the mobile call from the mobile network to a wireless access point via the packet-switched network, such that the call is conducted via a wireless communications link using the wireless access point.
A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:
- establishing, with a mobile network, a control messaging link for exchanging mobile control channel signaling data and a voice channel link for exchanging audio data for a mobile call;
- sending a signal strength indicator to the mobile network thereby causing the mobile network to recognize the gateway as a valid path for handing off the mobile call;
- establishing a communications link with a packet-switched network;
- and
- routing the mobile call from the mobile network to a wireless access point via the packet-switched network, such that the call is conducted via a wireless communications link using the wireless access point.
