  • Patent number: 8611307
    Abstract: Methods and systems facilitating a server-assisted scan for a preferred network are disclosed. A user device may identify a cell at a present location of the user device, and request one or more records associated with the identified cell from a server. If the server provides a record associated with the identified cell, the user device may determine whether the provided record includes preferred network data identifying a preferred network previously found on the identified cell. If the provided record does not include the preferred network data, the user device may start a scan timer that is set to a predefined time interval. If the provided record includes the preferred network data, the user device may initiate a preferred network scan without starting the scan timer.

  • Patent number: 8532652
    Abstract: Methods and systems for autonomous search for Closed Subscriber Groups (CSGs) cells in wireless networks are disclosed. A user device determines current situational indicators of the user device and compares the current situational indicators to previously-recorded situational indicators stored in the user device. The user device also selects, based on the comparison, a closed subscriber group (CSG) cell from a list of CSG cells in the user device. Lastly, the user device searches for the CSG cell based on a proximity of a first location associated with the current situational indicators of the user device to a second location associated with the previously-recorded situational indicators of the CSG cell.

  • Publication number: 20130107718
    Abstract: Methods and systems for prioritizing application data in a wireless user device are disclosed. A user device receives, at an application transport bearer (ATB) entity of a protocol layer of a network interface of a user device, at least a portion of a data packet originating from an application identified for prioritized data transfer on the user device. Then, the ATB entity of the user device schedules the data packet ahead of any data packets processed at any network-established data radio bearer (DRB) entities on the same protocol layer as the ATB entity. The ATB entity of the user device is also configured to operate on a protocol layer of a subset of protocol layers on the user device and is configured by the user device with a higher priority parameter than any of the network-established DRB entities on the same protocol layer as the ATB entity.

  • Publication number: 20130079001
    Abstract: Methods and systems for reducing service acquisition time of a user device are disclosed. A method includes receiving a request to turn off the user device, obtaining network information for a future destination of the user device, and powering off the user device. The method further includes utilizing the network information for the future destination of the user device to reduce service acquisition time when the user device is powered on.

  • Publication number: 20130044660
    Abstract: Methods and systems facilitating a preferred network scan in a 4G communications system are disclosed. A user device identifies a new search event when operating in connected state. The user device transitions to idle state, performs a preferred network scan, and returns to connected state.

  • Publication number: 20130044613
    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.

  • Publication number: 20130007039
    Abstract: Methods and systems for optimizing cell searches in a mobile communication system supporting variable channel bandwidths are disclosed. A user device stores data identifying frequency bands, networks associated with the frequency bands, and various channel bandwidths supported by the networks. The user device is operable to dynamically update the stored data upon detecting a new network associated with one of the frequency bands.

  • Publication number: 20120252368
    Abstract: A user device performs a set of measurements at a specified rate when the user device in a discontinuous reception (DRX) mode, and determines a signal condition of a signal received from a serving cell. The user device adjusts the specified rate based on the signal condition. The reduction in the rate may reduce a current drain by the user device when the user device is in the DRX mode.
