  • Patent number: 8270988
    Abstract: A method is disclosed for implementing an overlay carrier frequency in a wireless coverage area in response to low load in the coverage area. Normally, an carrier frequency may be added in response to high load. However, the disclosed method involves adding a carrier frequency in response to low load, as the addition of a carrier may advantageously increase the likelihood of soft handoff in certain situations, and as low load may facilitate operation on the added carrier without the need to add expensive supporting infrastructure that would typically be added to support full operation on an added carrier frequency.

  • Patent number: 8271000
    Abstract: Disclosed herein is a method for repeat paging in a wireless communication system. In accordance with the method, a RAN controller will send a repeat-paging directive to a plurality of BTSs to cause each BTS to begin broadcast of a series of page messages destined to a target mobile station. While transmitting the series, one of the BTSs will then receive from the mobile station a page response, and the BTS will responsively provide to the RAN controller a notification of the page response. In response to receipt of the notification, the RAN controller will then send a paging-stop directive to at least each other BTS of the plurality, and each BTS that receives the paging-stop directive will responsively discontinue broadcasting the series of page messages before completing broadcast of the entire series of page messages, thereby helping to conserve air interface resources.

  • Patent number: 8271040
    Abstract: A network element (230) for communicating with a wireless communication unit (214) in a communication cell (200) of a communication system (200) comprises a receiver arranged to perform a frequency sweep across a plurality of operational frequencies. Signal processing logic (255), operably coupled to the receiver, processes the received signals from the frequency sweep and providing an estimate of a level of interference at a number of frequency carriers of the swept frequencies. The signal processing logic (255) is capable of determining whether a transmit power level at a frequency selected from the processed frequency sweep satisfies at least one predetermined quality criterion of the communication system (200). A transmitter (270) is arranged, upon initial activation of the network element (230), to transmit to a wireless communication unit at the determined transmit power level.

  • Patent number: 8265626
    Abstract: A method of setting up a connection in a communication system is provided, wherein the communication system includes a user equipment (UE). The present method includes following steps. When a first radio resource control (RRC) connection request message is received from the UE, whether the first RRC connection request message has been received before is determined. If the first RRC connection request message has been received, a first RRC connection setup message is sent back to the UE. If the first RRC connection request message has not been received, whether there is an accessible Femto access point (FAP) near the UE is further determined. If there is the accessible FAP near the UE, a first RRC connection reject message is sent back to the UE. If there is no accessible FAP near the UE, the first RRC connection setup message is sent back to the UE.

  • Patent number: 8249023
    Abstract: A packet switched radio telecommunication system supporting hard handover adapts Always_on technology to a link between a target packet data serving node (PDSN) and a support PDSN. The support PDSN assigns a temporary IP address to a mobile terminal in its service area, and transmits handover data and the mobile terminal's temporary IP address to the target PDSN via a direct link when the mobile terminal leaves the service area. The target PDSN, upon receiving a registration request for the temporary IP address from the mobile terminal moved to its service area, temporarily registers the temporary IP address in an IP pool. The target PDSN receives down-link frame data for the mobile terminal at the temporarily registered IP address from the support PDSN via the direct link. A new temporary IP address is assigned by the target PDSN when data transmission/reception is complete to the mobile terminal.
