摘要： 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).

摘要： 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 (101) utilizes protocol gateways (211) 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 (101) utilizes a mediation device (405) that generates and/or translates network messages according to multiple different network protocols and utilizes multiple HLRs (401, 403) or home agents, each supporting a different network protocol.

摘要： A wireless terminal is disclosed that is capable of establishing a communications channel with either a public wireless network or a private wireless network on existing IS-95 CDMA facilities without changing the air interface or requiring the existence of independent private network facilities. Furthermore, a wireless terminal is disclosed that enables a user of a wireless terminal to affect which private wireless network the wireless terminal accesses, again on existing IS-95 facilities and without changing the air interface. The wireless terminal comprises two or more lists of SID/NID signals: a default list and at least one override list. Both the default list and the override list provide a different preference for which public or private network the wireless terminal accesses when a call is placed from the wireless terminal. A switch in the wireless terminal advantageously causes the wireless terminal to use either the default list of SID/NID signals or one of the override lists of SID/NID signals. The switch can be activated either manually by the user or by inserting the wireless terminal into a cradle in accordance with the present invention.
摘要翻译：公开了能够在现有IS-95 CDMA设施上与公共无线网络或专用无线网络建立通信信道的无线终端，而不改变空中接口或要求存在独立的专用网络设施。此外，公开了一种无线终端，其使得无线终端的用户能够再次在现有的IS-95设施上影响无线终端访问的专用无线网络，并且不改变空中接口。无线终端包括两个或更多个SID列表 / NID信号：默认列表和至少一个覆盖列表。默认列表和覆盖列表为从无线终端发出呼叫时无线终端访问的公共或专用网络提供不同的优先级。无线终端中的交换机有利地使无线终端使用SID / NID信号的默认列表或SID / NID信号的覆盖列表之一。根据本发明，可以由用户手动激活开关或者通过将无线终端插入到支架中来激活。
