Abstract: A controller receives a new resource request from a user equipment associated with a first talk group. The new resource request is a request for an assignment of one of MBMS resources and unicast resources for user equipment associated with the first talk group. The controller identifies a second geographical area in which members of the first talk group are located, determines that MBMS resources are available in the second geographical area, and determines whether the first talk group is an MBMS eligible talk group in the second geographical area. In response to determining that the first talk group is an MBMS eligible talk group in the second geographical area, the controller assigns MBMS resources to the first talk group; otherwise, the controller assigns unicast resources to the first talk group.

Abstract: A method and network element are provided that perform admission control in a wireless communication system by, in response to receiving a new bearer request associated with a user equipment (UE), can free up bearers currently allocated to the UE when the UE's bearer limit is reached. In response to receiving a bearer request associated with the UE, the method and network element determines a number of bearers currently allocated to the UE, wherein the UE is limited to a maximum number of bearers, and when the UE currently is allocated its maximum number of bearers, determines a priority associated with the bearer request, compares the determined priority to a priority associated with each bearer currently allocated to UE to produce one or more comparisons, and based on the one or more comparisons, determining whether to preempt a currently allocated bearer to admit the requested bearer.

Abstract: A method, apparatus (100) and system (200) for altering the playback speed of recorded content (105) to match a target syllable rate is provided. A user may enter a desired, target playback syllable rate through a user interface (101), such as a keypad or touch screen. Alternatively, the target playback syllable rate may be determined from identification of the source of the recorded content (105). An actual playback syllable rate (106) associated with the recorded content (105) is then determined. The recorded content (105) is then altered, by time domain harmonic scaling in one embodiment, such that the altered playback speed (109) substantially matches the target playback syllable rate. In so doing, a listener is able to receive recorded content (105) at a faster or slower rate than it is produced.

Abstract: A method for optimizing the use of at least one shared communication channel and at least one dedicated communication channel in a communication system. First, communication of a first plurality of communication traffic is allocated to a dedicated communication channel. Similarly, communication of a second plurality of communication traffic is allocated to a shared communication channel. Next, a change is detected in one or more channel performance metrics of the shared communication channel. When the detected change is a degradation in the one or more channel performance metrics of the shared communication channel, communication of at least one of the second plurality of communication traffic is re-allocated to the dedicated communication channel. When the detected change is an improvement in one or more channel performance metrics of the shared communication channel, communication of at least one of the first plurality of communication traffic is re-allocated to the shared communication channel.

Abstract: An apparatus including a processor 42 coupled to a memory 44 resides in a location call filtering center 36 and cooperates with a gateway mobile location center 34 and a mobile switching center 22 to process a communication signal, based on the geographical location of a communication device 28, such as a mobile telephone. The processor 42 accesses a user location filter database 46 stored in the memory 44 which contains a set of subscriber conditions/preferences that may be used to identify a processing operation to be performed on the call. The processor 42 further operates as an Internet web page server to afford mobile subscribers Internet 56 access to the user location filter database 46 so that the mobile subscribers may enter and/or edit the set of conditions/preferences stored in the memory 44.

Abstract: A method for operating a core router that provides multiple levels of service to packets is provided. The core router receives packets from input links, and accepts or drops them based on the level of congestion in the outgoing link it is destined for. The level of congestion is determined by comparing the queue length of the output queue of the link with a configurable maximum queue length, and by comparing the rate at which the queue length is increasing with a configurable maximum rate of queue length increase. A threshold value is computed based on the above measurements, and this value is updated periodically based on the level of congestion in the system.

Abstract: A communication device (106) transmits a data packet at a first transmission time or during a first transmission time period to a data controller (116). The data controller determines an earliest transmission time or time period of data packets to be acknowledged and transmits an indication that only data packets transmitted after the earliest transmission time or time period will be acknowledged. The communication device then determines whether the data controller is indicating that only data packets transmitted after the first transmission time or time period will be acknowledged. When the data controller is indicating that only data packets transmitted after the first transmission time or time period will be acknowledged, the communication device retransmits at least a portion of the data packet and thereby performs timerless error recovery.

Abstract: A method for providing adaptive modulation in a radio communication system employs a plurality of data modulation techniques (207). A two-way communication unit (100) automatically selects (318) from amongst the plurality of data modulation techniques (207), and uses the selected data modulation technique to transmit (308) data.

Abstract: For each of one or more received trellises, a convolutional decoder (808) determines a path metric (812) and a signal strength estimator (809) determines a signal strength estimate (813). A signal quality estimator (810) processes the path metrics and signal strength estimates for each of the received trellises and produces a received signal quality estimate (814), the received signal quality estimate being indicative of a signal-to-interference-plus-noise ratio, a bit error rate, or a block error rate. This approach is well-suited for use with schemes having high-order symbol constellations. When incorporated into an RF transceiver 700, the received signal quality estimate can be used in the selection of an encoding scheme best adapted to ongoing RF channel conditions.

Abstract: For each of a plurality of modulation techniques, corresponding data reception history information is stored. A particular modulation technique is selected from amongst the plurality of modulation techniques (52). At least one block of data is transmitted using the particular modulation technique (55). A message is received that provides information regarding reception of the at least one block of data, including whether reception of each of the at least one block of data occurred without error (56). The data reception history information is updated for the particular modulation technique using the information regarding reception (57). The data reception history information is used to determine an estimate of transmission signal quality (51).

Abstract: A communication device (200) supporting transmissions provides transmission related device temperature control. The communication device (200) has a particular portion (244) subject to an increase in temperature resulting from the transmissions. A message is provided for transmission by the communication device (200) which has a data communication protocol (224) governing message transmission. Temperature control is effected by determining temperature information for the particular portion (244) of the communication device (200) and by modifying operation of the data communication protocol (224) based in part on the temperature information.
