  • Publication number: 20120252465
    Abstract: A method for updating location of a user equipment in a cellular system is disclosed. The method comprises the user equipment receiving route update radius information 220. The user equipment further calculates a route update radius from the received route update radius information 230 by using a random number generated by the user equipment. The user equipment then transmits the calculated route update radius to a cellular network 240. Alternatively, the method comprises the cellular network receiving a route update message from a user equipment 420. The cellular network further calculates a route update radius 430 using a random number generated by the cellular network. The cellular network then unicasts the calculated route update radius to the user equipment 440.

  • Publication number: 20120173654
    Abstract: An apparatus and method is provided that ensures virtual content providers such as advertisers that their virtual content will reach every mobile device, every application within each mobile device and/or every user. Such functionality is referred to herein as a “guaranteed reach”. Guaranteed reach parameters including reach type parameters (mobile devices, applications and/or users) are specified in a memory. A server receives a virtual content request and a received target identification uniquely identifying, for example, the requesting device via a network. The server identifies virtual content candidates from the memory by comparing the received target identification to the stored target identification associated with the virtual content. The guaranteed reach parameters may also include frequency-based criteria that guarantee a frequency of impression(s) for particular virtual content and guaranteed priority criteria to ensure the guarantee will be met.

  • Publication number: 20120044814
    Abstract: The present disclosure is directed to a method for reporting uplink buffer status of a relay station to a base station in a wireless network. The method includes monitoring an uplink buffer of the relay station communicating with the base station, where the uplink buffer comprises data to be transmitted from one or more user terminals to the base station. The method further includes sending an uplink buffer status report from the relay station to the base station, where the uplink buffer status report includes occupancy status information of the monitored uplink buffer and a number of user terminals having data queued up at the relay station to be transmitted to the base station.

  • Publication number: 20090245337
    Abstract: The present invention is directed to a method that includes determining 302 a distribution of channel conditions across a plurality of physical resource blocks (PRBs) (202-206) and dividing (304) the distribution of channel conditions into a plurality of levels (208-226). The method also includes ordering (306) a ranking of each of the plurality of PRBs according to an instantaneous channel condition for each of the plurality of PRBs and selecting (308) one of the plurality of levels corresponding to an observed condition for each of the ranked plurality of PRBs. In addition, the method includes reporting (310) a mean value of the channel conditions across the plurality of PRBs and a bit value for the selected level for each of the ranked plurality of PRBs.
