摘要： A method for channeling network traffic is described, which includes identifying, with an agent disposed within a client computer of the network, a portion of the network traffic associated with the client computer that has compliance related interest. The identified compliance interesting traffic portion is encapsulated with a header. Apart from the encapsulated traffic portion, the network traffic is routed according to its designated destination. The interesting traffic portion however is diverted on the basis of the encapsulating header. The diverted traffic portion is channeled for compliance related processing. Upon being channeled, the traffic portion is processed according to a compliance related policy. The processing is performed remotely from the client computer.

摘要： A push-to-talk conference call is conducted over a packet switched network. Participants send a request and receive approval before being allowed to talk during the conference call. In one implementation, only one of the participants is enabled to transmit audio packets while other participants are only allowed to receive audio packets.

摘要： Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.

摘要： Devices, softwares and methods are provided for redundantly encoding a data stream into frames for network transmission as packets. A main encoder encodes a data stream into main frames, while a redundant encoder encodes it into redundant frames. The redundant frames have a redundant-coding delay from the main frames that is adjustable to accommodate many different sets of network conditions.

摘要： Wideband telephones, gateways, adapters, software, and methods are provided for implementing wideband telephony over a network. A WB IP telephone has a WB telephone, a codec for encoding voice into voice data bits, and a packetizer for encoding groups of the voice data bits in intermediate packets. An adapter for an analog WB telephone has a digital to analog converter, a codec and a packetizer. The intermediate packets are generally not in form that would be ready for network transmission. The WB IP telephone also includes a modem for connecting to the network over a telephone line. A voice gateway receives the encoded voice, and adds packet headers to it, to make it suitable for transmission through the network to a cooperating gateway. The cooperating gateway in turn strips the headers for the receiving WB IP telephone. The WB IP telephones can thus be connected to the network using only PSTN lines.

摘要： Devices, software, and methods quantify a burstiness quality of the packet loss in the node of a path. The quantified burstiness becomes a metric for determining the Quality of Service (QoS) offered by a node in retransmitting data through a network. Network routing and rerouting decisions are made according to the improved QoS. The burstiness statistic is determined by counting lengths of episodes of sequentially discarded packets at the node. The burstiness statistic is incorporated as a metric with the other metrics of the QoS of the node.

摘要： A mobile station includes a first wireless interface that can couple to a first wireless network, a second wireless interface that can couple to a second wireless network, and a controller. The controller can negotiate a first wireless link with the first wireless network using the first wireless interface and establish a communication session with a remote device using the first wireless link. The controller can also detect a session handoff trigger, negotiate a second wireless link with the second wireless network using the second wireless interface in response to the session handoff trigger, and invoke a private branch exchange feature to transfer the communication session from the first wireless link to the second wireless link.

摘要： A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station, the mobile station being operable to roam between a private and a public network. The mobile station is signaled via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits. One or more features associated with a private network are delivered to the mobile station during the communication session as an end user moves between the public and private networks.

摘要： A method for handing off a call between networks includes monitoring a quality of a first link between a mobile station and a wireless local area network (WLAN) when the mobile station is actively connected with the WLAN on a call and monitoring a quality of a second link between the mobile station and a cellular network when the mobile station is actively connected with the WLAN on the call. The method also includes handing off the call from the WLAN to the cellular network when the quality of the first link is less than a handoff trigger threshold for a drop count duration and when the quality of the second link is greater than a minimum cellular link quality threshold.

摘要： Systems and methods are provided to facilitate efficient routing of unlicensed mobile access (UMA) communications. In one implementation, a method of providing a communication link between a first mobile station and a second mobile station through a customer premises equipment (CPE) device includes intercepting a call setup request provided by the first mobile station and received at a security gateway of the CPE device. An address associated with the second mobile station may be extracted from the call setup request and the address may be compared with a plurality of records maintained by the CPE device. A call setup request may be forwarded to the second mobile station if the address corresponds to at least one of the records. The first and second mobile stations may be in communication with the CPE device over a wireless local access network (WLAN) in accordance with an unlicensed mobile communication standard.
