A Base Station (BS) includes a controller, a first generator, a second generator, and a modulator/demodulator (modem). The controller determines to apply one of a first power control which is slot-periodic and a second power control which is frame-periodic.

The second generator generates a second power control command at a frame period using a channel quality premising an equalizer according to the second power control, and generates a third power control command according to a predefined pattern at a slot not being able to use the channel quality. The modem transmits at least one of the first, second, and third power control commands.

Abstract: A network learns capability information indicating whether a user equipment (UE) is capable of simultaneous and independent operation in multiple component carriers (CCs). The network configures a monitoring pattern for each of multiple CCs that are configured for the UE in dependence on the received capability information. The capability information derives from the UE's RF layout; if the UE is capable of such simultaneous and independent operation the network can assign for the CCs different monitoring patterns that are independent of one another and the UE will have no gaps where it cannot take or send a measurement. This knowledge is particularly useful if the CCs are frequency non-contiguous with one another. If the UE is not so capable, the network must assign monitoring patterns to that UE for all its configured CCs that are not independent of one another.

Abstract: Systems and methods for arbitrating among traffic from a coherence point to a switch fabric. A multi-level arbiter is used to avoid starvation while providing fairness and high bandwidth on the connection path between the coherence point and the switch fabric. A first level of arbitration selects packets with enough available credits for forwarding from the switch fabric on a downstream channel. The second level of arbitration arbitrates among short packets at a first arbiter and arbitrates among long packets at a second arbiter. The selected short packet and the selected long packet are forwarded to a third level of arbitration. The third level of arbitration alternates between long and short packets and forwards the selected packet to the switch fabric.

Abstract: A cluster compute server includes nodes coupled in a network topology via a fabric that source routes packets based on location identifiers assigned to the nodes, the location identifiers representing the locations in the network topology. Host interfaces at the nodes may be associated with link layer addresses that do not reflect the location identifier associated with the nodes. The nodes therefore implement locally cached link layer address translations that map link layer addresses to corresponding location identifiers in the network topology. In response to originating a packet directed to one of these host interfaces, the node accesses the local translation cache to obtain a link layer address translation for a destination link layer address of the packet. When a node experiences a cache miss, the node queries a management node to obtain the specified link layer address translation from a master translation table maintained by the management node.

Abstract: A method and system for provisioning circuits on multiple parallel links with a single setup message is disclosed. A setup message specifying links in a circuit path is transmitted to switches along the circuit path. If a switch determines that a link specified in the setup message has insufficient bandwidth for the circuit, the switch substitutes a parallel link having sufficient bandwidth for the specified link in the circuit path. The setup message can indicate whether substitution for a link is permitted. This can be used to prevent substitution for links when provisioning service routes for new circuits in order to maintain diversity requirements, while allowing substitution for links when provisioning restoration routes for failed circuits in order to reduce restoration time.

Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

Abstract: Application MGIDs defining virtual groups of output destinations are assigned by applications and appended to packets to specify on a per-application basis how packets associated with the application should be handed by a network element. The application MGIDs are mapped to single system MGID number space prior to being passed to the network element switch fabric. When a packet is passed to the switch fabric, the application MGID header is passed along with the system MGID header, so that the packet that is passed to the switch fabric has both the system MGID as well as the application MGID. The switch fabric only looks at the system MGID when forwarding the packet, however. Each egress node maintains a set of tables, one table for each application, in which the node maintains a list of ports per application MGID. The egress node uses the application MGID to key into the application table to determine a list of ports, at that egress node, to receive the packet.

The master and slave device may map their times to the counter by sending respective request packets to the switch and receiving respective completion packets including respective counter values from the switch. The master and slave device may determine respective time values corresponding to the respective counter values based on in-switch delays of the packets.

Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

A transmitting device, which may be one of the plurality of devices that corroborates characteristics or collaborates information, may generate and transmit the report message comprising the collaborated information. A receiving device may provide the message over a communications network, or the report message may continue to be handed off between devices capable of direct communication, the message eventually reaching a device that is within range of the communications network.

Abstract: A temporary ENUM architecture assigns a temporary ENUM at call time. For an originated communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides consistency with the specific format required by the receiving party.

The TempENUM service gateway includes a TempENUM database, a module that assigns a suitable TempENUM at the time of call routing, and a module that handles a lookup in the TempENUM database, and maps the assigned TempENUM to a calling party identifier (CgPID). The TempENUM database stores a TempENUM from a coordinator system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication the initial caller.
