    Abstract: A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities, available transport format combinations (TFCs), and transmission time interval (TTI) constraints of transport frames within the TFCs is disclosed. A subscriber unit (12) has applications that produce separate data streams. Example applications include voice (32), signalling (34), E-mail (36) and web applications (38). The data streams are combined by a multiplexer module (48) into one data stream called the transport stream (50). The transport stream (50) is sent over the reverse link to base station transceivers (BTS) (14). The multiplexer module (48) multiplexes the data streams onto a single stream according to available TFCs, TTI constraints, data stream priorities, and current maximum transmitter power constraints.

    Abstract: A system, apparatus, and method provides location services to a mobile station by employing equipment identity information. In one aspect of the present inventive concept, a location server uses the equipment identity information of a mobile station in order to select the best protocol for LCS communication. In another aspect of the inventive concept, a mobile station uses the equipment identity information of a location server to select the best protocol to use for LCS communication. Advantageously, the equipment identity information can be used to correct manufacturing defects, fix design flaws and software bugs, track performance, optimize performance, or any combinations thereof. Information about features and defects relating to equipment identity information may be determined and stored for future use.

    Abstract: Methods and apparatus for handing over a mobile station in the system from a CDMA base station to a GSM/TDMA base station are disclosed. A hybrid GSM/CDMA telecommunications system 20 includes base stations 32 operating according to a CDMA interface, and base stations 30 operating according to a GSM/TDMA interface. A communications link is established over the CDMA interface with a mobile station 40. Data is received at the CDMA station from the mobile station 40, in response to a signal received by the mobile station over the GSM/TDMA interface, without breaking the communications link with the CDMA station. The data includes a measurement of the signal strength. The mobile station is handed over from the CDMA to the GSM/TDMA base station in response to the data received, while a weighting factor is applied to the measurement of the signal strength. In particular, a method of conducting intersystem handover from a multicarrier system to a direct spread system is provided. Timing synchronization is also made available through the mobile station.

    Abstract: Feedback from user stations to the base station for a multicast/broadcast transmission is performed by decoding multicast/broadcast data received from a transmitter on a downlink resource, forming a feedback message corresponding to the reception of the multicast/broadcast data, and queuing the feedback message for transmission to the transmitter on an uplink resource. The uplink resource used corresponds to the downlink resource used for the multicast/broadcast transmission. For unicast transmissions the uplink resource is dedicated to an uplink transmission corresponding to a downlink transmission on the downlink resource.

    Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transition s that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice- versa. Such transmission techniques enable seamless delivery of content acro ss cell borders and/or between different transmission schemes such as Point-to- Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting differen t streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

    Abstract: A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities and available transport frame combinations (TFCs) is disclosed. A mobile station 12 has applications that produce separate data streams. Example applications include voice 32, signaling 34, E-mail 36 and web applications 38. The data streams are combined by a multiplexer module 48 into one data stream called the transport stream 50. The transport stream 50 is sent over the reverse link to base station transceivers (BTS) 14. The multiplexer module 48 multiplexes the data streams onto the transport stream according to their priorities and the available TFCs.
