    摘要： A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.

    摘要： A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.

    摘要： A method of maintaining call quality in a communication system by communicating between a base site (101) and a communication unit (113) on a first channel. The communication unit (113) monitors the downlink communication signal (116) transmitted by the base site (101) and determines a characteristic of the first channel. The communication unit (113) is then handed off to a second channel having a less aggressive reuse pattern, based on the characteristic of the first channel.

    摘要： A communication system receives and codes a plurality of information signals according to coding assignments to produce a plurality of coded baseband signals. From these signals, a simulated composite carrier signal is formed which has all the characteristics of an actual composite carrier signal which would have resulted if the plurality of coded baseband signals had been formed. The simulated composite carrier signal is analyzed to determine its peak-to-average ratio. The communication system selects a different coding assignment for coding the plurality of information signals if, based on the determined peak-to-average ratio and a selection criteria, the coding assignment does not produce the desired results. The communication system selects a different coding assignment until at least one or several desired coding techniques have been identified, ranks the coding techniques and makes a final selection of the coding techniques to meet the peak-to-average ratio requirements.

    摘要： In a TDMA cellular network, there is provided a mechanism for shared-carrier frequency-hopping. It comprises: allocating on a frame basis within a reuse diameter to one coverage area (A-I) during certain timeslot(s) at least one from a pool of TDM frame-hopped carriers and allocating on a frame basis within that carrier reuse diameter to another coverage area (A-I) during certain other, substantially non-overlapping timeslot(s) that frame-hopped carrier, all in substantially non-interfering time-synchronism with any proximal reuse of that carrier, whereby the advantages of frequency hopping are obtained. Stated differently, it comprises: at one instant in time, allocating within a reuse diameter to one coverage area (A-I) at least one of a plurality of hopped carriers and at that same instant in time, allocating within that carrier reuse diameter to another coverage area (A-I) another of that plurality of hopped carriers, all in time-synchronism with any proximal reuse of that carrier. The control and access carriers may also be included in the hopping pool, causing certain timeslots to be hopped on a sequence different from the others. The pool of hopped carriers is further apportioned among co-located sites into hopping groups, thereby reducing intra-system synchronization requirements. To solve the near/far problem, TDM timeslots bordering hopping boundaries are preferentially allocated to less distant mobile users.

    摘要翻译： 在TDMA蜂窝网络中，提供了用于共享载波跳频的机制。 它包括：在重用直径内的一个帧基础上，在一个或多个TOS跳帧载波池中的至少一个时隙期间在一个覆盖区域（AI）内分配一个覆盖区域（AI），并且在该载波重用直径内以帧为单位分配给另一个 覆盖区域（AI），其在某些其他基本上不重叠的时隙中与跳帧载波完全无干扰地与该载波的任何近端重用时间同步，从而获得跳频的优点。 换句话说，它包括：在一个时刻，在重用直径内向一个覆盖区域（AI）分配多个跳跃载波中的至少一个，并且在同一时刻，在该载波重用直径内向另一个覆盖范围 （AI）该多个跳跃载波中的另一个，其全部与该载波的任何近端重用时间同步。 控制和接入运营商也可能包含在跳频池中，导致某些时隙以不同的顺序跳频。 跳跃式运营商池进一步在共址网站中分配到跳频组，从而降低系统内同步要求。 为了解决近/远问题，邻接跳频边界的TDM时隙优先分配给较不相关的移动用户。
