20110051660 | METHOD AND SYSTEM FOR ACQUISITION OF NEIGHBOUR CELL INFORMATION - A system and method for acquisition of neighbour cell information are provided. A serving cell receives a request for neighbour cell system information, and in response to the request, the serving cell transmits neighbour cell system information. | 03-03-2011 |
20110053586 | RADIO LINK TIMEOUT PROCEDURE FOR CALL RE-ESTABLISHMENT - A radio link timeout procedure for call re-establishment is provided. A mobile station receives signals over a wireless link, determines whether there is a potential call re-establishment as defined by at least one condition, and decides whether radio link failure has occurred on the basis of the signals received over the wireless link such that while there is a potential for call re-establishment as defined by the at least one condition, a decision that a radio link failure has occurred is made earlier than if there is no potential for call re-establishment. | 03-03-2011 |
20110053595 | ACCESS PROCEDURE FOR CALL RE-ESTABLISHMENT - An access procedure for call re-establishment is provided. In a first method, a mobile station, in at least some instances of detecting radio link failure, attempts call re-establishment on multiple cells concurrently. In a second method, a mobile station performs a first random access channel procedure when the mobile station is not aware of at least two cells with enabled call re-establishment, and performs a second random access channel procedure when the mobile station is aware of at least two cells with enabled call re-establishment. | 03-03-2011 |
20110105120 | METHODS AND APPARATUS TO MONITOR A CHANNEL TO DETERMINE NEIGHBOR CELL INFORMATION - Methods and apparatus to monitor a channel to determine neighbor cell information are disclosed. An example method for a first mobile station to determine cell information for a first cell disclosed herein comprises monitoring a channel for messages containing cell information, receiving a first message via the monitored channel and addressed to a second mobile station, the first message including first cell information, and storing the first cell information for a time period after receiving the first message. | 05-05-2011 |
20110105158 | METHODS AND APPARATUS TO AVOID TRANSMISSION OF REDUNDANT NEIGHBOR CELL INFORMATION TO MOBILE STATIONS - Methods and apparatus to avoid transmission of redundant neighbor cell information to mobile stations. An example method to avoid transmission of at least some neighbor cell system information from a network to a mobile station disclosed herein comprises receiving neighbor cell system information, setting a validity indication representing whether the mobile station has valid neighbor cell system information associated with a neighbor cell, and sending the validity indication to the network. | 05-05-2011 |
20110116470 | OPTIMIZED RESOURCE ALLOCATION FOR WIRELESS DEVICE IN PACKET TRANSFER MODE - A system and method allows a network, in response to a cell reselection notice, to serve a wireless, wireless device sufficient data to complete a pending data transfer instead of performing the immediate cell change. Appropriate allocation of radio resources to the wireless device in the current serving cell and before cell change allows reduced packet data transfer latencies for small data sessions, better load balancing and traffic resourcing between cells, appropriate allocation of uplink resources in the new target cell, and enhanced control over network congestion. | 05-19-2011 |
20110116474 | OPTIMIZED RESOURCE ALLOCATION FOR WIRELESS DEVICE IN PACKET TRANSFER MODE - A method and system for a wireless device configured to communicate with a network is presented. The network is communicated with at a radio link control layer. An indication is communicated to the network that a higher layer protocol is operating in an acknowledged mode. The higher level protocol is above the radio link control layer. In some implementations, the higher level protocol terminates at a device located outside the network. A resource allocation is received from the network. The resource allocation is at the RLC layer. | 05-19-2011 |
20110134908 | SINGLE SLOT DTM FOR SPEECH/DATA TRANSMISSION - The present document relates to radio transmission. In particular, the present document relates to the single-slot dual transfer mode (DTM) available e.g. in GSM/GPRS/GERAN networks. A transmitter is described. The transmitter is configured to send circuit switched data over a traffic channel to a corresponding receiver, wherein the traffic channel is segmented into a plurality of frames. The transmitter if further configured to determine a vacant frame of the plurality of frames, wherein no circuit switched data is sent in the vacant frame due to discontinuous transmission; and to send packet switched data over the traffic channel using the vacant frame. | 06-09-2011 |
20110201279 | METHODS AND APPARATUS TO PERFORM MEASUREMENTS - Methods and apparatus to perform measurements are disclosed. An example method disclosed herein for a user equipment (UE) to perform measurements in a mobile communication network comprises receiving configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion to configure a measurement, and performing the measurement based on the configuration information. | 08-18-2011 |
20120027006 | SYSTEM AND METHOD FOR JOINT VOICE AND DATA TRANSMISSION - A method for multiplexing voice and data communication using a communications network is presented. In the method, at least one voice bit from a voice bit stream is retrieved, and at least one data bit from at least one data bit stream is retrieved. When the voice bit stream is not in a discontinuous transmission (DTX) period, the at least one voice bit and the at least one data bit are used to generate a modulated symbol. The method includes transmitting the modulated symbol using the communications network. | 02-02-2012 |
20120309404 | METHODS AND APPARATUS TO PERFORM MEASUREMENTS - Methods and apparatus to perform measurements are disclosed. An example method disclosed herein for a user equipment (UE) to perform measurements comprises receiving configuration information from a network, the configuration information to configure the UE to perform logging of measurements in an idle mode, logging measurements in the idle mode, and sending an indication that logged measurements are available. | 12-06-2012 |
20120315890 | METHODS AND APPARATUS TO PERFORM MEASUREMENTS - Methods and apparatus to perform measurements are disclosed. An example method disclosed herein for a user equipment (UE) comprises receiving configuration information from a network, the configuration information to configure the UE to perform logging of measurements in an idle mode, wherein the configuration information includes a duration, and storing the configuration information at the UE. | 12-13-2012 |
20130100839 | OPTIMIZED RESOURCE ALLOCATION FOR WIRELESS DEVICE IN PACKET TRANSFER MODE - A system and method allows a network, in response to a cell reselection notice, to serve a wireless, wireless device sufficient data to complete a pending data transfer instead of performing the immediate cell change. Appropriate allocation of radio resources to the wireless device in the current serving cell and before cell change allows reduced packet data transfer latencies for small data sessions, better load balancing and traffic resourcing between cells, appropriate allocation of uplink resources in the new target cell, and enhanced control over network congestion. | 04-25-2013 |
