    Abstract: A typical radio frame (300) comprises A, B, and C vocoded bits (304). At the end of each frame (300) A and B bits (305) are inserted from a previous frame. Thus, each frame not only comprises A, B, and C bits (304) for that frame, but also comprises those A and B bits (305) originally transmitted in a prior frame. Thus, each frame comprises high and low priority vocoded bits (304) from the current vocoder frame, and those higher priority bits from a preceding frame (305). By placing an inner CRC (302, 303) around the most important bits of the vocoded frame, even though a frame is erased (e.g. its outer CRC (301) failed) it can still be verified that the most important bits in the vocoded frame are correct. Since the class B and C bits can tolerate some errors, the vocoded frame can then play out if its inner CRC passes.

    Abstract translation: 典型的无线帧（300）包括A，B和C语音编码比特（304）。 在每个帧（300）的末尾，从前一帧插入A和B位（305）。 因此，每个帧不仅包括用于该帧的A，B和C比特（304），而且包括原来在先前帧中发送的那些A和B比特（305）。 因此，每个帧包括来自当前声码器帧的高和低优先级声码比特（304），以及来自前一帧（305）的那些较高优先级比特。 通过在声码帧的最重要位周围放置内部CRC（302,303），即使帧被擦除（例如，其外部CRC（301）失败），仍然可以验证在声码帧中最重要的位 是正确的。 由于类B和C位可以容忍一些错误，所以如果其内部CRC通过，则声码帧可以播放。

    Abstract: An improved non-linear processor used in echo cancellation eliminates a comfort noise source (214) and instead inputs a control signal (224) directly into a noise suppression system (403). The noise suppression system (403) uses the control signal (224) to inhibit the iterative update of the background noise estimate when the control signal (224) is active, which prevents any residual echo from biasing the noise estimate provided by the noise suppression system (403). Additionally, the control signal (224) is used by a gain calculator (533) within the noise suppression system (403) to attenuate each frequency band to the maximum allowable amount plus the current residual channel signal-to-noise ratio (SNR). Depending on the implementation, the noise suppression system (403) models the background noise of either a user of the PSTN or a user of a mobile station.

    Abstract: An apparatus and method is provided for adjusting a Quality of Service (QoS) for a communication device in a communication network. One step includes registering an application from a service provider with the communication device and the communication network. Another step includes receiving, by the communication device, a token from a token provider that permits a modified QoS level for the registered application. Another step includes sending the token by the communication device to the communication network. Another step includes negotiating the QoS level between the service provider and the communication device, dependent at least in part on the reception of the token. Another step includes providing, for the communication device, the modified QoS level permitted by the token for the registered application.

    Abstract: An apparatus and method for efficient transitions between operating states in a communication network (100), includes a preliminary step of having a mobile station (118) in a Dormant or Idle state. A next step includes requiring a data transfer, either to or from the mobile station (118). A next step includes transitioning the mobile station (118) from the Dormant or Idle to an Active state. A next step includes transferring a bearer path context for the data from a Paging Control Function (PCF) (108) to an RF Bearer Function (110). This can include creating a tunnel using an Inter-PCF handoff procedure. The result is a direct connection between an RF Bearer Function (110) and an IP Router (106), without the PCF (108) being in the data path.

    Abstract: A communication system implements detection of bad frames of information by utilizing multiple bit correction thresholds. Equipment used within the communication system adapts to different signaling environments by dynamically altering the bit correction threshold based on a history of the number of consecutive bad frames of information that have been previously erased and the number of bits corrected by a channel decoder (202). By implementing this dynamic bit correction threshold, sufficent bad frame indication (BFI) detection and receiver sensitivity can be obtained simultaneously, which results in an improved perceived audio quality to the end user.

    Abstract: A method for managing a communication session between a first communication device and a second device in a communication network (100) is disclosed. The communication session is conveyed between a service-provider server and the first communication device via a first communication link. The method at the first communication device includes requesting (204) a third communication device to be associated with the communication session. The first communication device requests the third communication device, via a second communication link. The second communication link is substantially transparent to the service-provider server. The method also includes determining (206) whether the third communication device can be associated with the communication session. Further, the method includes requesting (208) the service-provider server to associate the communication session with the third communication device when the third communication session can be associated with the communication session, via a third communication link.

    Abstract: A communication system (100) provides a clear channel link for transport of encrypted payload across a network (140) of the communication system. When a source access network (106) receives, via an air interface (104), a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header to across the network, for example, to a destination access network (126). Based on the added header, the source and destination access networks are able to perform clear channel synchronization.
