In some instances, the UE may receive an indication of scheduled uplink time of the MWS RAT via a physical layer communication. The UE may schedule communications of the WCN RAT based at least in part on the indication of future activity.

Abstract: Methods and systems for optimizing voice call setup times for user devices. A user device that is registered to a packet switched network and in an idle state receives a command to establish a voice call. The user device selects a legacy cell of a circuit switched network. The user device then establishes a radio connection with the selected legacy cell without first establishing a radio connection with a serving cell of the packet switched network.

Abstract: Embodiments reduce the time and energy expended to establish an initial link to a network. Some embodiments use either active or passive scans to discover available access points and then use a broadcast or multicast Generic Advertisement Service (GAS) Request message to identify access points providing requested services. Other embodiments use a broadcast or multicast GAS Request message to identify access points or mobile devices providing requested services without first scanning for access points. Only access points or mobile devices providing requested services need to respond to the GAS request message. Duplicate messages received by multiple access points coupled to the same network can be filtered so only one message is received and responded to.

Abstract: Systems and methods are provided to improve roaming performance and to minimize disruptions in connectivity. When roaming between a source AP and a target AP, the device determines whether the APs employ different gateways, such as through an ARP exchange. If the source and target APs have different gateways, a DHCP exchange is used to renew the IP address of the device to restore network connectivity.

Abstract: Packets are transmitted by a server to mobile nodes in a coverage area of a wireless network using a coverage and reliability map, which indicates qualities and reliabilities of links between the server and the nodes. When a new packet is received in the server, the server transmits the packet if a current load of the packets including the new packet is less than a peak load constraint. Otherwise, the new packet is delayed for one time slot. Packets are transmitted according to associated priorities.

Abstract: Systems and methods for service execution across legacy telecommunications networks and Internet Protocol Multimedia Subsystem (IMS) domains are described. In one aspect, a convergence gateway is deployed in an IMS network to interface between the IMS network and a legacy circuit-switched (CS) telephony network (legacy network). The convergence server extends legacy network-supported circuit-switched services (including voice supplementary services, enhanced voice services, and messaging) to IMS core network subscribers. To this end, the systems and methods rely on the legacy network to implement supported circuit-switched services and generate corresponding results. The corresponding results are adapted to a signaling protocol and state model for the IMS network and provided to one or more IMS subscribers.

Abstract: In a network system in which a large number of terminals that transmit information exist and data extraction is performed via a wide area network, when data filtering is performed by using terminals called entrance nodes, existing in front of the wide area network, efficient operation of the entrance nodes is a goal to achieve.

In a further implementation, through a query and reply exchange about allocations of filtering and quick response processes to be executed by entrance nodes, reallocating process items, pre-filtering of necessary data, and relaying data between entrance nodes are performed.
