Method and apparatus for integrated wireless communications in private and public network environments
First Claim
1. A method for operating a private base transceiver station, the private base transceiver station having at least one radio transceiver that communicates data and signaling information with a mobile station, the private base transceiver station also having a mobility management processing function and a call control processing function contained within it, the private base transceiver station also having an interface for connecting to a packet data network, the method comprising the steps of:
- receiving a call control message at the private base transceiver station and passing the call control message to the mobility management processing function resident within the private base transceiver station, without forwarding the call control message elsewhere, the call control message including a control function identifier and a mobile station identifier;
forwarding the call control message internally within the private base transceiver station to a packet network interface in the private base transceiver station, the packet network interface providing an interface for the private base transceiver station to communicate messages to other nodes; and
at the packet network interface, formatting an external control message intended for transmission via the packet network interface.

Abstract
A communication system formed by a private network that includes a private wireless network. The communication system includes a public wireless network using a public wireless protocol, such as GSM, and includes public networks, such as PSTN, ISDN and the Internet, using a wired protocol, such as 1P. The private network also includes a local area network (LAN) and the private network connects to the public networks using a wired packet protocol, such as IP. The public and private wireless networks operate with the same public wireless protocol, such as GSM, and the private wireless network additionally operates with a wired packet protocol, such as IP. The communication system permits users to operate freely in both public and private wireless networks using standard mobile stations while achieving high private network data rates. The communication system uses normal wireless handsets or other mobile or fixed stations without need for any modifications.

15. A computer readable storage medium encoded with a computer program for operating a private base transceiver station, the private base transceiver station having radio transceivers that communicate data and signaling information with a mobile station, the private base transceiver station also having a mobility management function and a call control function contained within, the private base transceiver station also being connected to a packet data network, comprising:
-
an encoded computer program for receiving a call control message at the private base transceiver station and passing the call control message to the mobility management function resident within the private base transceiver station, without forwarding the call control message to a base station controller, the call control message including a control function identifier and a mobile station identifier; an encoded computer program for forwarding the call control message internally within the private base transceiver station to a packet interface function in the private base transceiver station, the packet interface function for connecting the private base transceiver station to the packet data network; an encoded computer program for formatting an external control message intended for transmission over the packet data network, the formatted external control message indicating an alias identifier corresponding to the mobile station identifier; and an encoded computer program for transmitting the external control message into the packet data network. - View Dependent Claims (16)

17. A private base transceiver station having a radio transceiver function that communicates data and signaling information with a mobile station, the private base transceiver station also having a mobility management function and a call control processing function contained within the private base transceiver station also having a packet network interface for connecting to a packet data network, the private base transceiver station further comprising:
-
a transceiver operable to receive a call control message and to pass the call control message to the mobility management function resident within the private base transceiver station, without forwarding the call control message to a base station controller, the call control message including a control function identifier and a mobile station identifier; a packet network interface layer operable to receive the forwarded call control message internally within the private base transceiver station, the packet network interface layer further operable to provide communication between the private base transceiver station and other nodes; and a processor within the private base transceiver station, for formatting an external control message intended for transmission over the packet data network, the formatted external control message indicating an alias identifier corresponding to the mobile station identifier. - View Dependent Claims (18)

19. A private base transceiver station, having a radio transceiver that communicates data and signaling information with a mobile station, the private base transceiver station also having a mobility management function and a call control function contained within it, the private base transceiver station further connected to a packet data network, comprising:
-
means for receiving a call control message at the private base transceiver station and for passing the call control message to the mobility management function resident within the private base transceiver station, without forwarding the call control message to a base station controller, the call control message including a control function identifier and a mobile station identifier; means for forwarding the call control message internally within the private base transceiver station to a packet network interface in the private base transceiver station, the packet network interface operable to provide communication between the private base transceiver station and the packet data network; means for, formatting an external control message intended for transmission over the packet data network, the formatted external control message indicating an alias identifier corresponding to the mobile station identifier; and interface means, for connecting to the packet data network and transmitting the external control message into the packet data network. - View Dependent Claims (20)
