Abstract: A wireless multi-hop network is formed by exchanging a control message including a HELLO message and a topology message between a plurality of communication terminals. A communication terminal adjusts a control message transmission interval so as to reduce the control load according to its movement state and transmits a control message at a longer transmission interval as the movement becomes smaller. Moreover, when link information is updated, the communication terminal includes the sequence number of the HELLO message in the topology message transmitted. Thus, it is possible to realize stable communication in accordance with a movement characteristic with a small message transmission frequency.

Abstract: A mobile communication system provides a phone number maintaining service. In the system, a first mobile switching center (MSC) receives a call request signal with calling terminal information and called terminal information, detects an initial service provider of a called terminal from the called terminal information, and transmits the call request signal to a communication network formed by the detected initial service provider of the called terminal. A second MSC detects a changed service provider of the called terminal based on the called terminal information included in the call request signal transmitted from the first MSC, and transmits the call request signal to a communication network formed by the detected service provider. A third MSC transmits the call request signal received from the second MSC to the called terminal so that the called terminal can communicate with the calling terminal over a communication network formed by the changed service provider.

A plurality of data packets whose packet time lengths are approximately equal to each other are selected regardless of their receiver terminals. The transmissions of the plurality of selected data packets are commenced simultaneously by use of a plurality of radio channels.

Abstract: A wireless broadband communication system that operates with high efficiency and reduced latency in long range point-to-point and point-to-multipoint applications. The system includes multiple transceivers and multiple antennas for transmitting and receiving wireless signals using TDD techniques over multiple channels, which include a control channel for setting both the size of the transmit bursts and the modulation threshold level. By determining the size of the transmit bursts for a subsequent data transmission based upon the number of filler packets detected in a specified number of previously received bursts, and adjusting the modulation threshold level for the subsequent transmission based upon the transmit burst size, the system provides increased data throughput, while maintaining the packet error rate at an acceptable level. As the throughput requirements of the system are relaxed, the modulation threshold levels can be adjusted to provide reduced packet error rates.

Abstract: A method for multicast routing for a telecommunications network comprising a plurality of communication nodes interconnected by multiple paths, for the establishment of a multicasting connection between a source node and a plurality of destination nodes, in which the destination nodes are informed that a multicast connection request is arriving from a particular source. Each destination node then sends a connection request to the source, and these requests are processed and relayed by each node within the network. The requests are propagated from node to node until they reach the source node, carrying the information on the cost accumulated along the path. Finally, the source node, having received the information on the costs of the possible paths, selects the path which has a satisfactory cost.

Abstract: An emergency call recognition system which is activated when an off-hook situation occurs, which recognizes when an emergency number is dialed with or without the presence of a dial tone, and which provides the caller a communication channel to complete such a call. The present invention is used to give priority to emergency telephone calls. Typically the present invention is used in wireless local loop systems, however the present invention can also be incorporated into a conventional telephone system. The present invention uses an emergency call recognition system to determine if a person is dialing an emergency telephone number. If the emergency call recognition system recognizes a dialed telephone number as an emergency telephone number, then the caller is provided with a communication channel to complete the telephone call. The caller is provided a communication channel even if all of the communication channels are in use. This is accomplished by disconnecting calls that are not of an emergency nature.
