The method includes, when a plurality of Mobile Stations (MSs) receive a preamble signal from a cluster header through a dedicated control channel while the BS is disrupted, sending a message requesting cluster member subscription to the cluster header, in the cluster header, including the plurality of MSs in a cluster member, configuring a cluster member list, and broadcasting the cluster member list, in a source MS among the plurality of MSs, sending a data transmission request message to the cluster header using the broadcasted cluster member list, in the cluster header, one of unicasting and broadcasting a response message for the data transmission request of the source MS, and, in the source MS, transmitting data to a target MS among the plurality of MSs based on the response message. | 2012-02-16 |
20120039309 | Bandwidth sharing in a distributed wireless client application using inverse multiplexing termination - A system and method for bandwidth sharing in a distributed wireless client application using inverse multiplexing termination. The system includes: a group of collocated client playback devices having wide area network (WAN) and local area network (LAN) connectivity, and a centralized inverse multiplexing (IMUX) server which optimizes shared bandwidth of both the WAN via inverse multiplexing and the LAN using either broadcast or multicast of all virtual multiplexing paths to all other client playback devices of the group of collocated client playback devices. Other embodiments are disclosed. | 2012-02-16 |
20120039310 | LOCATION OF MOBILE NETWORK NODES - The physical position of an unknown node in a network is determined by sending a first sent WiFi signal from one of an unknown node and a first reference node having a known location, and repeating the sent WiFi signal in the other of the unknown node and first reference node with a first reply WiFi signal. A distance is derived between the unknown node and the first reference node from the time of flight of the first sent and first reply WiFi signals. A second WiFi signal is sent from one of the unknown node and a second fixed node having a known location, and repeating the sent second WiFi signal in the other of the unknown node and second reference node with a second reply WiFi signal, and A distance is derived between the unknown node and the second reference node from the time of flight of the second sent and second reply WiFi signals. A physical location of the unknown node is determined based on the derived distances between the unknown node and the first and second reference nodes. | 2012-02-16 |
20120039311 | VOICE CALL DETECTION - Systems and methods for detecting a voice call are described. In one aspect, a data stream is identified and analyzed to determine whether the data stream is associated with a single device. The data stream is further analyzed to determine whether it is actively communicating data packets and to identify a data packet size. Bandwidth for the data stream is reserved if the data stream is associated with a single device, is actively sending data packets, and the data packet size is smaller than a threshold value. | 2012-02-16 |
20120039312 | ENHANCED REGISTRATION MESSAGES IN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEMS - An enhanced Session Initiation Protocol (“SIP”) registration message having extended header information that is used by an Internet Protocol Multimedia Subsystem (“IMS”) core to determine the registration status of a mobile device and the physical location of the mobile device. The extended header information includes hardware and subscriber identifiers, such as an International Mobile Equipment Identity (“IMEI”) and International Mobile Subscriber Identity (“IMSI”). The IMS core queries an equipment identity register to validate IMEI/IMSI identifiers in the header to determine whether to deny registration to a mobile device. The IMS core also queries a capability database using an IMEI to determine which location determination techniques are supported by or suitable for the associated mobile device. | 2012-02-16 |
20120039313 | TECHNIQUES FOR MANAGING MOBILITY MANAGEMENT SIGNALING IN A WIRELESS NETWORK - Techniques are described that can be used for efficient mobility management signaling. In some cases, a network can specify an extended timer used for a machine to machine (M2M) type device to communicate with a network. The extended timer can be transmitted in connection with an attachment acceptance message, Location Updating Accept message, Tracking Area Update Accept, or Routing Area Update Accept message. In some cases, a timer can be adjusted using a multiplier in order to increase a period at which communications with the network occur. The network can transmit an indication to change a timer by multiplying the timer with the multiplier. | 2012-02-16 |
20120039314 | METHOD AND APPARATUS OF SUPPORTING WIRELESS FEMTOCELL CLUSTERS - A method of operating a femtocell network cluster is disclosed. One example method of operating the femtocell network cluster may include certain operations, such as, selecting a master femtocell access point among various femtocell access points operating on the femtocell network cluster and updating a master table to include the master femtocell access point in the master table neighbor list. Other operations may include transmitting the master table to each of the femtocell access points informing them of the identity of the master femtocell access point. The tables may be maintained by all of the femtocell access points operating on the network. | 2012-02-16 |
