  • Patent number: 9019933
    Abstract: Method and associated apparatus for communicating data at reduced transmission latency in a radio communication system having a slotted interface are described. An example network device includes an assignor to receive an indication of an amount of data to be communicated by a first communication station, and assign communication resources to convey all of the indicated data amount, the assigned communication resources comprising a plurality of time slots within one time frame and one radio carrier and a data scheduler to receive an indication of assigned communication resources, and to schedule communication of the data block in conformity with the assigned communication resources and in response to a communication station minimum tuning latency period, wherein the schedule of the communication of the data block provides for completion of the communication of the data block and acknowledgement of successful delivery of the data block within the one time frame.

  • Patent number: 8744442
    Abstract: An apparatus, and an associated methodology, for identifying to a circuit-switch-connected mobile station with an indication of packet-service capabilities available to a mobile station. A message generator at the network generates a message that includes an indication of the network-entity capabilities with respect to packet communications. A field of the message identifies the packet-service capabilities. A message is sent by the network and detected by a detector of the mobile station. A report is formed indicative of the value contained in the delivered message, and a user display displays an indication of the detected information.

  • Patent number: 8600381
    Abstract: A method, computer readable medium and mobile device for operating using more than one Radio Access Technology (RAT) are provided. When the mobile device is operating in a serving cell of a first RAT, it obtains, through at least one of wireless access radios in the mobile device, a first set of candidate information from a message transmitted for the serving cell. It also obtains, through at least one of the wireless access radios, a second set of candidate information from a message transmitted for a neighbor cell of the serving cell. The mobile device considers the candidate information from the first set and the candidate information from the second set for reselection by the mobile device.

  • Publication number: 20120184267
    Abstract: Systems and methods for achieving PLMN continuity when moving between networks of different types through network selection are provided. When a mobile station moves from a first network type, such as cellular, to a second network type, such as GAN, if there is a PLMN discontinuity, this may result in a dropped call. In order to avoid this, networks for the first network type and the second network type are selected such that there is PLMN continuity. This can involve reselection of a different cellular network than one currently providing service to the mobile station.

  • Patent number: 8095096
    Abstract: Apparatus, and an associated method, for a receiving station, such as the receive part of a mobile station, that has diversity antennas. The receiving station includes both legacy demodulators and a diversity demodulator. Calculations are made to determine signal indicia associated with the signal energy detected at the diversity antennas. Responsive to the signal indicia, selection is made as to whether to utilize demodulation data, demodulated pursuant to a diversity demodulation technique or pursuant to a legacy demodulation technique. As the characteristics of received signals change, reselection of the demodulation is correspondingly made, such as on a frame-by-frame basis of frame-formatted data.

  • Publication number: 20100267384
    Abstract: Systems and methods for prioritizing network selection to achieve PLMN continuity when moving between networks of different types are provided. In network centric embodiments, the network generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. In mobile station centric embodiments, the mobile station generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. This can be based on the mobile station recognizing past behaviour of the networks.

  • Publication number: 20100265893
    Abstract: Network methods and systems for maintaining PMLN continuity when moving between networks of different types as a function of PLMN continuity preference are provided. PLMN continuity preference concerns a preference for the mobile station when transferring from a first network type, such as cellular, to a second network type, such as GAN to reduce the possibility of dropping calls, for example. The network receives this preference information from the mobile station, and the network responds to registration requests based on the preference.
