摘要： Error bursts are detected and corrected in a communication system using shortened cyclic codes, such as shortened Fire codes. Data is loaded into a first error syndrome register and a second error syndrome register. The data in the registers may be evaluated to determine if the data bits contain a correctable error. Shortened zero bits are shifted into the second error syndrome register. A number of zero bits are shifted into the first error syndrome register to trap an error burst pattern in the data. A determination is made as to the number of zero bits shifted into the second error syndrome register to trap the location of the error burst in the data. Using the number of zero bits shifted into the second error syndrome register and the error burst pattern, the error in the data is located and corrected.

摘要： A method for handover execution in a wireless environment is provided that comprises communicating, by a mobile network, a handover command message to a physical layer of a mobile station to initiate a handover execution. The handover command message is received by the physical layer, which responds by tuning to a handed to frequency and by communicating physical layer bursts over the handed to frequency such that initial timing advance and power control setting characteristics are determined by the mobile network. The method also includes communicating a cease signal to stop communicating the bursts to the mobile station, which responds by ending the transmission of the bursts and by establishing a new communications link over the handed to frequency with the mobile network. The mobile station and mobile network may then couple to a voice or data path such that a wireless communication associated with the mobile station and the mobile network is facilitated.

摘要： A technique whereby a subscriber of a multiple access communication network such as a cellular communication system is permitted to make a reservation to guarantee availability of a shared physical communication resource, such as a cellular radio telephone traffic channel, at an appointed date, time and location. The reservation is made in advance by the subscriber requesting the network to mark a requested resource for the subscribers exclusive use during the requested period of time. The reservation may be made any number of ways, such as through the subscriber terminal itself, by making arrangements themselves or on their behalf by others at a conference call center, through Web servers connected through the Internet, or by other means. Whenever a resource of the requested type is available during the requested period, the controlling stations in the network reserve that resource for that subscribers' exclusive use as the appointed time draws near. Thus, when that subscriber attempts to originate or is expected to receive a call at the appointed time, the network is able to grant the on-hold resource to that subscriber. After the reserved period of time elapses, the network releases the reserved resource, and applies normal allocation rules to it.

摘要： A demodulator determines a time of arrival of an access signal. Access signals that do not result in a time of arrival are discarded. Upon obtaining a time of arrival, the access signal is equalized and a training sequence of bits in the equalized access signal is compared to a reference sequence of bits. A burst confidence metric is obtained in the comparison by summing the number of matching bits. The access signal is discarded if the burst confidence metric is less than a threshold number. A decoder performs a parity check on access signals that have a burst confidence metric exceeding the threshold number. The access signal is discarded if the parity check fails. Upon passing the parity check, the access signal is re-encoded and compared to its received version. If a number of errors from the comparison exceeds a bit error threshold, the access signal is discarded.

摘要： A technique for implementing a flattened Layer 3 stack model within a Global System for Mobile (GSM) communication system so that a centralized multiplex function associated with certain functions handles messages. The multiplex function dispatches radio resource (RR), mobility management (MM), or Connection Management (CM) function messages directly to the respective functional layers without first requiring such messages to pass through a stack. In the preferred arrangement, the multiplex function sub-L3 handles only uplink messages, allowing downlink messages to travel through the sub-layer stack without employing any bridging entity. The multiplex function can run independently of any of the other functions in Layer 3 or can be implemented as part of the message passing part of the Layer 2 running body so that the Layer 2 messages are routed directly to a respective RR, MM, or CM function. The flattened protocol stack permits time-sensitive messages related to location update, handover, or cell reselection and other time-critical messages to be handled more efficiently.
