  • Patent number: 8335512
    Abstract: A method of network resource release processing is provided, which includes the following steps. After user equipment (UE) using idle mode signaling reduction (ISR) mechanism registers to two 3rd Generation Partnership Project (3GPP) communication networks, when the UE changes from the 3GPP network to a non-3GPP communication network, a serving gateway (serving GW) receives a message sent from a peer endpoint network element (NE), and deletes network resources established by the two 3GPP communication networks for the UE according to the message. A mobility management NE and a serving GW are also provided. Through the method and device of network resource release processing, the resources are released when the UE using the ISR mechanism changes from the 3GPP network to the non-3GPP communication network.

  • Patent number: 8331930
    Abstract: For each one of a plurality of broadcast control channels, a mobile device measures a signal strength level of a radio frequency (RF) signal from a wireless communication network. The mobile device then repeats the measuring at least one time so that at least one other signal strength level of the RF signal on the broadcast control channel is identified. The mobile device also receives and decodes information which is broadcasted on the broadcast control channel, and stores this broadcasted information in memory. The acts of receiving, decoding, and storing are performed after measuring the signal strength level of the RF signal, but prior to completion of an averaging function for calculating an averaged signal strength level of the signal strength levels.

  • Patent number: 8326310
    Abstract: A method for communications between neighboring wireless cells such as wireless regional area networks operating according to IEEE 802.22 specifications. The method involves scheduling inter-base station communications for over-the-air connections to allow neighboring base stations to communicate in environments where a single available channel is shared between the neighboring cells or where two or more channels used by two or more neighboring cells. In some embodiments, a bridge system, such as a bridge consumer premise equipment (CPE), positioned in an area of coverage overlap between two cells is used for inter-base station communications, and allocation and scheduling of bandwidth on the utilized channels is performed to provide interference free communications between the base stations. Existence announcements are provided in coexistence time slots and requests for bandwidth such as reserved and additional time slots are transmitted between the base stations using the coexistence time slots.

  • Patent number: 8315676
    Abstract: An integrated circuit including ; transceiver module, a beacon miss module, and a control module. The transceiver module transitions, at predetermined times, a wireless network device from an inactive mode to an active mode. The predetermined times are based on a dock used by the wireless network device while operating, in the inactive mode. The beacon miss module counts a number of delivery traffic indication message (DM) beacons missed by the transceiver module during each of a first predetermined period and a second predetermined period. The first predetermined period is shorter than the second predetermined period. The predetermined times do not occur during either of the first predetermined period or the second predetermined period. The control module adjusts the predetermined times based on the number of the DTIM beacons missed by the transceiver module during each of the first predetermined period and the second predetermined period.

  • Patent number: 8270365
    Abstract: A user equipment (UE) is provide which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.

  • Patent number: 8264993
    Abstract: A method and a multimode terminal for minimizing current consumption and simultaneously reducing a handover processing time when a handover occurs between communication networks which provide communication services using different mobile communication technologies. The communication network modems of the multimode terminal are interconnected via a one-to-one communication path, so that a handover target communication network modem is powered on only when handover actually occurs. In this way, by efficiently determining a time point when the handover target communication network modem is powered on, a processing time according to the occurrence of handover can be reduced, and additional current consumption can be minimized.
