Information between the network elements is transmitted in frames that are divided into time slots. The base station controller controls one or more base stations. Network element identification information has been fed into a network element to be installed, and the network element is physically connected to the system by means of the telecommunication connections.

Abstract: In a mobile communication system having mobile foreign agents, the present invention eliminates the use of multiple source/destination headers attached to an information packet during the tunneling operation by using either a decapsulation/encapsulation or a forwarding operation with the encapsulated information packet. Either of these operations reduces the overhead incurred in the multiple encapsulation headers by reducing encapsulation of the information packet to a single level. Upon receipt of the information packet at the foreign agent on the communications system, the information packet is directed to the mobile node using a routing chain table maintained by the foreign agent or a next hop routing table maintained by the foreign agent and each mobile foreign agent in the transmission path. Once implemented, these data structures can also assist with routing of information packets within the foreign subnetwork.

Abstract: A method and system for automatically adjusting charges to a pre-paid account in a telecommunications or distributed processing network following a failure in the network. After a service that is chargeable against the pre-paid account is initiated in the network, a failure in the network is detected. The failure prevents a charging node from receiving event data relating to the pre-paid account. After recovery from the failure, a message is sent to the charging node containing service status information. The charging node adjusts the account balance in accordance with the service status information.

Abstract: A data stream between transcoders of a mobile wireless system is subdivided into a first data stream with samples for transmission and a second data stream with signal parameters for reconstruction of user data and/or for signaling. Both data streams are transmitted at the same time permitting an improvement in the quality of transmitted data, e.g. speech data in a GSM network in tandem operation between mobile subscribers.

Abstract: A wireless data transport method, and a mobile terminal and an interworking function (IWF) device therefor. In the wireless data transport method performed using a mobile terminal, an IWF device and a server, a dialing is performed in the mobile terminal using a predetermined command with an identifier including an IP (Internet Protocol) address, and then RLP (Radio Link Protocol) between the mobile terminal and the IWF device is synchronized to establish a circuit-switched data (CSD) channel according to the command. Then, PPP (Point-to-Point Protocol)/TCP (Transmission Control Protocol) is performed in the IWF device according to the identifier, and a network interface channel is then opened by an AT (ATtention) processing unit of the IWF device according to the IP address of the identifier. Therefore, the mobile terminal can be connected directly to a network interface which is an Internet connect port, using a CSD channel which is preferred by network service providers, not using a modem.

Abstract: A method and apparatus for passively monitoring communications in a trunked communication system. Digital messages transmitted over a control channel at a particular frequency are monitored with a receiver. Transmitted communication signals are demodulated and stored. The stored signals are tested to identify messages and to extract talk group and channel assignment codes. If the talk group is a talk group of interest, the receiver is tuned to the frequency corresponding to the channel assignment code so that voice communications are monitored. The receiver is tuned to the control channel after each voice communication so that a communication including multiple transmissions on different frequencies is coherently monitored by retuning the receiver in accordance with the received channel assignment codes. In an alternative embodiment, separate receivers are provided for the control channel and for voice communications.

The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

Abstract: The present invention describes a method of migrating a mobile station, operating within an integrated D-AMPS/EDGE wireless telecommunication network, from the D-AMPS packet portion of the network to the EDGE/GPRS packet portion of the network. The technique includes accessing the control channels of both the D-AMPS and EDGE networks in order to obtain the necessary timing advance and packet transfer identifier for use with the GPRS packet system. In an embodiment of the invention, the MS makes a first access on a D-AMPS control channel to obtain a pointer to a reserved radio block on an EDGE packet control channel. The MS makes a second access on the EDGE control channel as specified by the reserved radio block which contains a particular frequency and timeslot location. The MS then sends a series of shortened bursts to the network such that a Timing Advance Index (TAI) value is calculated from the bursts and sent back to the MS.

Abstract: A satellite broadcast system and method, particularly useful for television signals, allows for local as well as nationwide broadcast service by allocating greater satellite resources to the more important local service areas. This is accomplished by broadcasting a non-uniform pattern of local service beams and designing the system to establish different service area priorities through factors such as the individual beam powers, sizes, roll-off characteristics and peak-to-edge power differentials. Frequency reuse is enhanced by permitting a certain degree of cross-beam interference, with lower levels of interference established for the more important service areas.
