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 IP. 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.

Abstract: A technique for mobility signaling between a Base Transceiver System (BTS) and Mobile Switching Center (MSC) in a mobile telecommunications system. The MSC is interconnected to a number of BTSs using one or more primary rate links using a protocol such as Integrated Digital Services Network (ISDN), including a number of bearer (B) channels for voice transmission and at least one data (D) channel for control function transmission. Standard call processing messages are utilized on the ISDN D channel to support basic telephone functions such as call origination, call termination, and call release as much as possible. However, an additional logical communication link is established over each ISDN D channel to accommodate mobility related messaging which may include messages such as hand-off and registration messaging needed to support mobile communications.
