Abstract: An apparatus for providing network access and application session services includes a wireless network access device for receiving packet data streams from or transmitting packet data streams to one or more subscribers, and for conveying the packet data streams to or from a network or other subscribers. The wireless network access device includes profile information relating to the one or more subscribers. The apparatus further includes one or more application session services that are provided as a component of the wireless network access device. The wireless network access device selects, based on the profile information, zero or more of the application session services to process the packet data streams. The wireless network access device can also determine an application state associated with the packet data streams, and can modify actions of at least one of the application session services according to the application state.

Abstract: A card guide is used in guiding a circuit board with respect to a chassis. The card guide includes a guide rail extending along the card guide in a first direction, an end portion configured for removably attaching the card guide to the chassis, and a finger extending in a second direction. The finger has a shape and size to allow interconnection with an adjacent card guide. The finger defines an endpoint of a space allowing airflow in a third direction past the card guide.

Abstract: A method and system are provided for reducing the number of wireless transactions between an application server and mobile subscribers in a wireless communications system. The communications system includes a plurality of wireless mobile subscribers communicating with network devices via the application server. Each of the mobile subscribers includes a lightweight client, and the application server includes an alias for each mobile subscriber. For each session between a mobile subscriber and a network device: the application server receives a communication from the network device intended to be processed at a client residing on the mobile subscriber in accordance with a given protocol.

Abstract: A method of renegotiating QoS levels of a communication link in one or more networks, the communication link having an initial QoS level prior to renegotiation, includes examining information flowing on the communication link between a first network endpoint and a second network endpoint. The method also includes determining, based on the information, a type of application being used by the first and second network endpoints for the communication link. The method further includes determining a QoS level that is suitable for the application, and negotiating with at least one of the one or more networks to procure resources associated with the network that will provide the suitable QoS level.

Abstract: A method and system for redirecting communication traffic of a prepaid subscriber of a wireless network includes determining when the subscriber has exhausted or nearly exhausted his usage quota, identifying a recharging facility to which the subscriber should be redirected to recharge his account balance, and redirecting the subscriber communication traffic to the recharging facility as a result of determining that the subscriber has exhausted or nearly exhausted his usage quota. The redirection can occur during an existing session or during the process of initially establishing a session.

Abstract: Data interconnections are managed in a mobile communications network having multiple packet control function entities (PCFs) and multiple packet data serving nodes (PDSNs), wherein each PCF and PDSN communicates signaling messages according to a mobile signaling protocol. Information for a Mobile Subscriber (MS) is received. The MS is associated with a same one of the PDSNs when the MS moves from a first area covered by a first PCF to a second area covered by a second PCF. It is determined that a first PCF has issued a first connection request on behalf of an MS. As a result of the first connection request, a selection protocol is executed a first time to select a PDSN that corresponds to the MS. It is determined that a second PCF has issued a second connection request on behalf of the MS. The selection protocol is executed a second time to select the same PDSN that was selected as a result of the first connection request.

Abstract: Resources for IP networking are managed. A field is added to an operating system kernel software procedure. The field references a virtual router context. Packet processing software code is modified to cause the packet processing software code to execute in accordance with the virtual router context.

Abstract: A system and method for reducing the latency or apparent latency of half-duplex (e.g. push-to-talk “PTT” wireless communications, including storing a voice message or a portion thereof while establishing a real-time half-duplex communication session to minimize the initial wait time experienced by the PTT session originator.

Abstract: A data and voice communication system includes communication between a line card and an accelerator card. Voice, data, and control traffic is received from the line card and is transmitted to the accelerator card via a physical link having separate voice, data, and control logical channels. The separate voice, data, and control logical channels are represented by labeled data packets.

Abstract: Apparatus is used in communicating in a data and voice communication system. The apparatus includes a line card and a crosspoint switch in communication with the line card. The apparatus also includes an accelerator card in communication with the line card and the crosspoint switch. The crosspoint switch is configured to provide a redundant communications path between the line card and the accelerator card.

Abstract: Advanced communications features are provided in a mobile communications network having at least one mobile switching center and at least one mobile station subsystem. The mobile switching center and mobile station subsystem each communicate signaling messages according to a mobile signaling protocol. An indication is received that a half-duplex mobile communications session is to be initiated between a first mobile station subsystem and a second mobile station subsystem. The first and second mobile station subsystems include full-duplex communications apparatus for use in full-duplex mobile communications sessions. The half-duplex mobile communications session relies on the first and second mobile station subsystems, and all of the reliance is only on the full-duplex communications apparatus. Mobile communications telephone calls are established with the first mobile station subsystem and the second mobile station subsystem.
