Abstract: A system and method have been provided for establishing communications with an existing Bluetooth protocol piconet. The master device of the piconet broadcasts a beacon frequency at a predetermined frequency. The beacon frequency includes the BD_addr of the master device, as well as clock information, so that an inquiring device monitoring the beacon can acquire the system timing and transmission hopping frequency sequence. In a contention period following the beacon frequency, the inquiring device transmits its own BD_addr. In response to receiving the inquiring device BD_addr, the master device provides the inquiring device with an AM_addr.

Abstract: In the Internet, a domain can be multi-homed to a first and a second domain by a first path and a second path, respectively. If one of the first or second paths becomes unavailable, a path still remains to communicate with a host attached to the multi-homed domain. However, due to the requirements of IPv6 in relation to allocating addresses to domains, packets received via the remaining path during a communication will not be recognised by the host at a transport layer. Therefore, the present invention overcomes this problem by making use of a dynamic address variation facility of IPv6 used for mobile nodes. The dynamic address variation facility also, advantageously, can act as a replacement for a content switch and can maintain communication of packets to and from the host as a result of a change of IP address of the host caused by, for example, an administrative need to change the IP address of the host.

Abstract: A system and method for increasing bandwidth usage between an access point and a wireless device are described. One embodiment can include an access point, a prioritizer, and a priority storage device. These components can increase bandwidth usage between an access point and a wireless device by allocating previously unused transmission slots.

Abstract: A scalable edge node for servicing different video content simultaneously using two or more servers and for load balancing between the servers. Additional servers may be added or removed as the client demand serviced by the edge node changes. The node further includes a storage device that is shared between the servers, avoiding the need for multiple storage devices. The invention avoids prior architectures designed with a fixed number of servers and/or various other edge node elements, which are either too many or too few, and therefore become uneconomical or overwhelmed over a range of client demands.

Abstract: An inband signaling modem communicates digital data over a voice channel of a wireless telecommunications network. An input receives digital data. An encoder converts the digital data into audio tones that synthesize frequency characteristics of human speech. The digital data is also encoded to prevent voice encoding circuitry in the telecommunications network from corrupting the synthesized audio tones representing the digital data. An output then outputs the synthesized audio tones to a voice channel of a digital wireless telecommunications network.

Abstract: Apparatus, and an associated method, for facilitating formation of a RANcast in a radio communication system. An identifier identifies when a selected number of mobile user endpoints within a cell of a radio communication system are to receive the same multicast data. When the number exceeds a selected threshold, a RANcast is implemented by a RANcast implementer in which a common channel is used to broadcast the multicast data to all the mobile user endpoints.

Abstract: In a communications network, communications terminals exchange call control capability data which mutually identifies selected call control protocols and network address types. The terminals subsequently set up a call using protocols chosen from those identified. The terminals may continuously monitor for a request for the exchange of such data, allowing other parties to join a session subsequently, after the initial set up.

Abstract: A communication system (10) supports the provision of a plurality of dedicated communication resources (50–64), such as copper drops, RF links and optical fibers, to dedicated home-gateway devices (44–48) or distribution points (124). The communication resources (50–64) support broadband interconnection (104) between the dedicated home-gateway devices (44–48) or distribution points (124) and an access multiplexor (30) in a network (12). Each gateway device (44–48) or distribution point (124) generally includes a local RF transceiver (84) and associated control logic (80–82) that allows local communication (86) between gateway devices (44–48) and hence statistically multiplexed access (60–64, 89) to multiple communication resources, thereby providing increased bandwidth in uplink and/or downlink directions.

In a representative embodiment, a network measurement controlling system is provided according to the present invention, which comprises a control server, a router, and a meter connected to a network. The meter receives packets from a network and measures the number of packets, and the like, according to preset measurement rules, and transfers measured data to a control server. The control server holds control rules including its control policy for assuring the quality of each communication service, analyzes measured data transferred from the meter, and transmits control commands. The router controls the QoS automatically in real time according to the status of the network by receiving control commands and controlling communication service quality.

Abstract: The present invention relates to a method and system of relaying calls with a tone provision function in the next generation mobile communication network. The call relaying procedures and functions support a Voice over Internet Protocol (VoIP) function between an originating gateway controller and a terminating gateway controller, by modifying the Bearer Independent Call Control (BICC) protocol, while receiving the tone from an external tone generating device using the BICC protocol, Media Gateway Control Protocol (MGCP), and 3rd Generation-Inter-Operability Service (3G-IOS) protocol in the next generation mobile communication network based on an Internet Protocol (IP). The BICC, MGCP and 3G-IOS protocols improve the IP-based network by supporting the VoIP function between the originating gateway controller and the terminating gateway controller, while receiving the tone from an external tone generating device.

Abstract: An apparatus for processing packets in a multimedia terminal has a media access controller to send and receive packets from a network. A digital signal processor converts a series of incoming real-time transfer protocol packets into an incoming digital signal and converts an outgoing digital signal into a series of outgoing real-time transfer protocol packets. A compression-decompression unit decompresses the incoming digital signal and generates an output signal to an output device and compresses an input signal from an input device and generates an outgoing digital signal. A central processing unit sends and receives transmission control protocol packets. The apparatus can store a packet in one of a plurality of queues in a buffer and assign a priority to the packet based on whether the packet is a real-time transfer protocol packet or a transfer control protocol packet.

Abstract: In a digital communication system, communication stations constitute frames to be conveyed over an interface. The frames simultaneously comprising full rate speech data and dedicated user data. A speech coder in the digital communication system generates the speech data while operating at a full rate. A user data application in the digital wireless communication system generates the dedicated user data. The system can set different service configurations supporting simultaneous transmission of speech data and dedicated user data, and can also include signaling data in the frames.

Abstract: Methods are described that enable host devices of a multicast IP network to reliably join multicast group address(es) in talkgroup or point-to-point calls. For a talkgroup call, a sourcing host sends “hello” packets or payload to one or more network devices, addressed to a multicast group address. The receiving host issues a join command to the one or more network devices in an attempt to reliably join the multicast group address. If any packets are received by the receiving host within a designated time period associated with the attempt, the receiving host is reliably joined to the multicast group address. For a point-to-point call, a controller sends a pair of multicast group addresses, one designated for sourcing packets and the other designated for receiving packets, to a first and second host participating in the point-to-point call. The designated “source” and “receive” multicast group address are complementary for the first and second hosts.

Abstract: A communication method can inform a WLAN-to-WAN handoff process as a function, at least in part, of a determined likely future quality of service (35). In particular, a comparison (36) can be made as between the likely future quality of service being afforded by the WLAN and one or more threshold values that represent acceptable levels of service. In one embodiment projected likely quality of service values as correspond to different future points in time can be used to more completely inform the evaluation process.

Abstract: A method enables the introduction of a 200 kHz GSM-type network into a TDMA system having a bandwidth that is substantially less than a 2.5 MHz bandwidth normally employed for GSM-type networks. The method provides a 52-multiframe containing 12 blocks of four consecutive frames, two idle frames, and two control channels, and rotates the control channels belonging to a serving time group over odd timeslot numbers as 7, 5, 3, 1, 7, 5, . . . , etc. Preferably the rotation occurs between frame numbers (FN) mod 52=3 and 4. Information specifying at least the rotation direction is signalled to the mobile station in a downlink synchronization channel.

Abstract: In a method of communicating a plurality of parallel data packets from a first data parallel bus to a second parallel data bus, each of the plurality of parallel data packets is separated into a first portion and a second portion. Each first portion is converted into a first serial data stream and each second portion is converted into a second serial data stream. The first serial data stream is transmitted over a first serial data channel and the second serial data stream is transmitted over a second serial data channel. The first serial data stream is converted into a plurality of first received portions and the second serial data stream is converted into a plurality of second received portions. Selected first received portions are combined with corresponding selected second received portions so as to regenerate the plurality of parallel data packets.
