It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesAccess to telecommunications networks in multi-service environment Shared interworking function within a mobile telecommunications network Automatic data service selection Method and system for transmitting a data communication from a calling communication unit associated with a wireless communication system to a called communication unit G3 facsimile transmission method on CDMA cellular networks Method of servicing asynchronous communication data calling and incoming call signalling in code division multiple access mobile communication network Disc saw felling head chip path management construction Transmission of data packets over CDMA type cellular telephone Telecommunication subscriber connection using a domain name system Method for making mobile-to-mobile wireless data communication Patent #: 6349224 InventorAssigneeApplicationNo. 223177 filed on 12/30/1998US Classes:370/474, Assembly or disassembly of messages having address headers370/320, Code division (CDMA)370/356, Routing circuit switched traffic through a packet switching network370/398, Centralized switching375/222, Modems (data sets)379/220.01, With interexchange network routing455/428Switching or routingExaminersPrimary: Ton, DangAssistant: Phan, Tri H. Attorney, Agent or FirmInternational ClassH04J 003/24Foreign Application Priority Data1998-12-15 KRAbstractA data communication system and data communication operating method capable of providing a asynchronous data communication service to a public switching telephone network, X.25 network, and Internet by extensively applying a packet assembler deassembler (PAD) function to an interworking function device provided in a code division multiple access (CDMA) type data communication system. If a certain mobile station requests the asynchronous data service, the data communication system analyzes the condition of terminating information inputted by a user of the mobile station, and selectively connects the mobile station to a public switching telephone network, X.25 network, and Internet according to the result of analysis.Field of SearchAssembly or disassembly of messages having address headersRouting circuit switched traffic through a packet switching network Having residual echo cancellation or suppression Centralized switching Combining or distributing information via code word channels using multiple access techniques (e.g., CDMA) Auxiliary data signaling (e.g., short message service (SMS)) Switching or routing Interface attached device (e.g., interface with modem, facsimile, computer, etc.) Switching unit detail (e.g., mobile telephone switching office (MTSO), base station controller (BSC), etc.) Base station detail Interexchange signalling Modems (data sets) | |
