Abstract: Methods, apparatuses and systems directed to synchronizing transmissions among parent and child routing nodes in a hierarchical wireless mesh network. In one implementation, the present invention employs a time slot scheduling algorithm to coordinate communications between wireless nodes of a hierarchical tree. In one implementation, the present invention provides a wireless mesh network where slot scheduling information propagates throughout the mesh, while individual nodes in the mesh compute their respective time slot schedules based on this information and the current state of the network. In one such implementation, a parent routing node computes its slot schedule and transmits certain parameters to its child nodes (as opposed to the schedule itself). The child node(s) then iterates the same scheduling function based on the parameters passed to it to determine the slots with which it should communicate to its parent node and its child nodes.

The netmods pass a received packet, through a switching fabric, to the bridging application, which determines a relay location for the packet and whether the relay location is among the other set of netmods. Responsive to an affirmative determination, the bridging application uses the translation data structures to translate the packet before relaying the packet to the relay location.

Abstract: An administration of telephony applications conventionally using domain controller-based access authorization methods is provided such to eliminate the need for these methods. In a network where terminal devices are connected to time division multiplexed or packet-oriented network components, a terminal device establishes a communication link to a terminal device-specific adaptation for telephony applications via an interface for telephony applications, and the authorization for importing data is verified. Data is imported via the communication link to affected applications or affected services of the network. Any terminal device can be used to import the data and that no special authorizations are required for access as the proprietary/license keys that are exchanged between the terminal device and the exchange and the domain controller provide protection from unauthorized access to the exchange and to the local network connected thereto.

Abstract: A mechanism for managing and enhancing communication streams in a VOIP service using SIP is discussed. SIP is used to manage and enhance a communication stream at a centralized switching element in the VoIP environment rather than at the communication stream endpoints. The communication stream set up by SIP is directed through a central switching element under administrative control rather than traveling directly between the stream endpoints. As a result, the media stream may be conditioned with treatments and may be provided with enhanced services at the central switching element without the specific treatments and services being supported at both stream endpoints. The use of the centralized switching element allows full administrative control of the VoIP environment.

Abstract: A packet communication address is delivered through in-band signaling over a circuit-switched network connection for a call, so the packet communication address can be used to establish a packet session outside the circuit-switched network. When the call is initiated from an initiating communication client to a terminating communication client using a directory number associated with the terminating communication client, a portion of the bearer path is established through the circuit-switched network between two network gateways. The packet communication address for the originating communication client may be received in a call establishment request by an originating network gateway. The originating network gateway will use in-band signaling over the bearer path to provide the packet communication address for the originating communication client to a terminating network gateway.

Abstract: A method and apparatus are described for providing non-packet switched service to a target radio access technology (RAT) network. A circuit switched (CS) service notification message is received by a wireless transmit/receive unit (WTRU). If the WTRU has been allocated a valid temporary mobile subscriber identity (TMSI), a paging response message including the valid TMSI is transmitted after an inter-system change is performed from a source RAT network to a target RAT network. The CS service notification message is for terminating a CS call request. The source RAT network may be a long term evolution (LTE) network, and the target RAT network may be a third generation partnership project (3GPP) network. Alternatively, if the WTRU has not been allocated a valid TMSI, a paging response message including an international mobile subscriber identity (IMSI) that identifies the WTRU is transmitted after the inter-system change.

Abstract: A system and method are described for reducing congestion in a wireless network. A wireless base station becomes congested when substantially all of the available base station airlink resources are being used during a period of time. It is useful, however, to distinguish between periods of congestion with few users and periods where a larger number of users are using the base station. When there are few users a congestion situation is not necessarily a problem, while it is more likely that users' quality of experience and quality of service suffers as the number of users increases. This system and method determines when a base station is congested and implements a congestion prime management scenario when the number of active users is above an activity threshold.

When the initial maximum segment size value is larger than the configured maximum segment size value, the network device is configured to replace the initial maximum segment size value with the configured maximum segment size value to create a modified synchronization message, and send the modified synchronization message to the second computing device for establishing the TCP socket connection.

Preferably, the compression and packetization interval is such that the bandwidth occupied by the voice IP packets is approximately half of the minimum average available bandwidth in the upstream direction, thereby maintaining acceptable latency and voice quality of the speech. Further enhancement is achieved by causing the ISP to also give priority to voice packets that are destined to the telephony adapter, over the data packets that are destined to the telephony adapter.

Abstract: An optimized gateway selection process of the present invention is based on a universal mobility manager (UMM), a component for inter-technology location management. The UMM is capable of holding location information for diverse cellular networks, as well as for Internet telephony systems. For cellular networks, UMM acts as a traditional HLR; for an Internet telephony network, it acts as the entities that are responsible for user/terminal registration (registrar in SIP, gatekeeper in H.323) and address resolution (proxy server in SIP, gatekeeper in H.323). An optimal gateway selection is possible based on location related information provided by the UMM which had not previously been available. Utilizing the newly available information enables a gateway to be selected which may, for example, enable the circuit switched portion of a call to now be minimized.
