    Abstract: A method and apparatus for operating a wireless telecommunication system utilizing code division multiple access (CDMA) over-the-air with a Global System for Mobile communications (GSM) A-interface based network is described. A CDMA radio frequency (RF) signal interface provides a bi-directional interface to a subscriber unit, and a Global System for Mobile (GSM) communications A-interface SS7 transport provides a bi-directional interface with GSM mobile services switching center (MSC). Additionally, a transparent message transport is provided over which signaling messages defined in the GSM A-interface protocol are exchanged between the GSM MSC and a subscriber unit. Other signaling message generating by the GSM MSC and subscriber unit are processed and various actions are taken in response, including the configuration and control of signal processing resources. This configuration and control includes the allocation of vocoding and devocoding resources in accordance with the requested type of service, and the invocation of CDMA based encryption capabilities. Other actions include the allocation of CDMA traffic channel processing resources and selection resources at the start of a signaling exchange between the subscriber unit and the BSS or MSC. These resources process both voice and data calls, and signaling messages, such as registrations, from the subscriber unit. The CDMA traffic channel resources are used to perform the IS-95 style CDMA signal processing functions including modulation and demodulation.

    Abstract: A METHOD AND SYSTEM FOR PROCESSING TELEPHONE CALLS WITHIN A DIGITAL WIRELESS TELEPHONE SYSTEM (101A) IS DESCRIBED. DURING THE INITIATION OF A TELEPHONE CALL FROM A WIRELESS SUBSCRIBER UNIT (100A) IT IS DETERMINED WHETHER THE RECEIVING SUBSCRIBER UNIT IS ALSO PART OF A DIGITAL WIRELESS TELEPHONE SYSTEM (101A; 100B) THAT HAS COMPATIBLE VOCODING CAPABILITY. IF SO, VOCODED DATA FROM THE DIGITAL WIRELESS TELEPHONE SYSTEM (101A) IS CONVERTED INTO TONES THAT ARE INTRODUCED INTO A WIRE BASED TELEPHONE SYSTEM FOR ROUTING TO THE APPROPRIATE RECEIVING DIGITAL WIRELESS TELEPHONE SYSTEM (101A; 101B). WHEN THESE TONES ARE RECEIVED BY THE RECEIVING DIGITAL WIRELESS TELEPHONE SYSTEM (101A; 101 B) THE VOCODED DATA IS REGENERATED BASED ON THE TONES AND THEN TRANSMITTED TO THE RECEIVING SUBSCRIBER UNIT (100B; 106B). IF THE ORIGINATING AND RECEIVING WIRELESS SUBSCRIBER UNITS (100A, 100B) ARE PART OF THE SAME DIGITAL WIRELESS TELEPHONE SYSTEM (101A), THE STEPS OF CONVERSION TO TONES AND INTRODUCTION INTO THE WIRE BASED TELEPHONE SYSTEM ARE OMITTED, AND THE CALL IS ROUTED COMPLETELY WITHIN THAT DIGITAL WIRELESS TELEPHONE SYSTEM (101A). IN ANOTHER EMBODIMENT OF THE INVENTION, THE STEP OF CONVERSION TO TONES IS ENTIRELY OMITTED AND THE VOCODED DATA IS PASSED BETWEEN THE TWO DIGITAL WIRELESS TELEPHONE SYSTEMS (101A, 101 B) VIA AN ALL DIGITAL CONNECTION SUCH AS AN A TM PACKET NETWORK OR A WIRE BASED TELEPHONE CONNECTION WHERE THE INTEGRITY OF DIGITAL INFORMATION IS ASSURED. WHEN A CONFERENCE CALL IS INITIATED BY ONE OF THE WIRELESS SUBSCRIBER UNITS (100A/100B) INVOLVED IN THE TELEPHONE CALL, DATA FROM BOTH WIRELESS SUBSCRIBER UNITS (100A, 100B) IS DEVOCODED AND PLACED INTO ANALOG FORMAT SO THAT IT CAN BE SUMMED. ADDITIONALLY, SIGNAL PROCESSING RESOURCES ARE ALLOCATED FOR THE CALL IF THE TWO ORIGINAL WIRELESS SUBSCRIBER UNITS (100A, 100B) WERE PART OF THE SAME PART OF THE SAME DIGITAL WIRELESS TELEPHONE SYSTEM (101A). WHEN THE CALL WAITING FEATURE IS ACTIVATED BY A WIRELESS SUBSCRIBER UNIT (100A) INVOLVED IN A PHONE CALL WITH ANOTHER WIRELESS SUBSCRIBER UNIT (100B) ADDITIONAL SIGNAL PROCESSING RESOURCES ARE ALSO ALLOCATED FOR BOTH THE INCOMING AND OUTGOING DATA ASSOCIATED WITH THE SECOND CALL SO THAT IT MAY BE PROPERLY PROCESSED. .FIG. 1 & 2

    Abstract: A fast and efficient packet transmission system and method for transmitting and routing packets through a digital communications network (101, 102, 103, 104, 105 and 106) which utilizes both variable length packets and fixed length packets, or cells, for achieving maximum efficiency and minimum delay in the digital communications network. Network efficiency is maximized by using variable length packets to transmit information across transmission lines (102) and network speed is maximized by using cells to route information to their intended destinations.
