A multiple-protocol home location register (MP HLR) comprises a processor, that generates network messages according to two or more network protocols and processes network requests and other messages to obtain information requested by two or more networks that support the two or more network protocols. One embodiment of the MP HLR () utilizes protocol gateways () that interpret network requests and generate, utilizing a common control procedures for multiple network protocols, queries to a database that provides a common source of data for supported networks. Another embodiment of an MP HLR () utilizes a mediation device () that generates and/or translates network messages according to multiple different network protocols and utilizes multiple HLRs () or home agents, each supporting a different network protocol.

Multiple-protocol home location register and method of use

Implementing and selecting between virtual private wireless telecommunications networks

Coupling together two or more communication systems that use different signaling protocols requires a protocol converter. A protocol converter is provided that includes interfaces to communications systems to be coupled together mimics the operation of the communications systems each interface is coupled to providing a seamless coupling between the systems.

Methods and apparatus for translating between telephone signaling protocols

A wireless cellular voice system and a wireless packet data system cover a common service area consisting of a plurality of cells, and share RF spectrum in providing their respective services to: AMPS phones, CDPD handheld data terminals, and combined AMPS-CDPD subscriber sets. Control of AMPS wireless communication and switching is vested in an AT&T 5ESS.TM. switch and an AT&T 3B20.TM. Access Manager. Control of CDPD communication is vested in a Sun SPARC Data Network Processor operating under standard CDPD protocol. A high speed bus of the Access Manager is extended to the SPARC processor to facilitate coordination of use of the shared wireless channels; and to allow the AMPS facility to originate data messages to combined AMPS-CDPD subscriber sets to implement AMPS data features, e.g., VOICE MESSAGE WAITING; ELECTRONIC MAIL NOTIFICATION; PAGING; and CALLER ID (CID); CALLER ID CALL WAITING (CID-CW).
