  • Patent number: 8325688
    Abstract: A method and apparatus for providing policy control in a wireless communication system. A mobile station generates a resource request for a communication service, where the resource request includes an identifier uniquely identifying a type of communication service. A packet data serving node receives the resource request for the communication service and selects a policy control entity to process the resource request. The selection by the packet data serving node is based at least on the identifier. The selected policy control entity performs policy control on the resource request.

  • Patent number: 8200210
    Abstract: In a method and device, simple hardware such as a standard User Equipment (UE), a mobile telephone, is used to collect the impulse response of a radio channel. The data generated is used to classify radio channels based on the impulse response estimates by estimating distribution parameters of the impulse response. This makes it possible to distinguish between different types of fading and hence, radio environments by matching the parameters to known radio channel models.

  • Patent number: 8185106
    Abstract: A method of accessing base station (BS) by subscriber station (SS) includes: after scanning signals of certain BS, SS starts ranging procedure and sends ranging request to the BS; the BS checks whether the SS belongs to the BS, if not belonging to the BS, then sends terminating ranging response to the SS; the SS interrupts the ranging procedure with the BS after receiving the terminating ranging response, and re-selects a new channel for ranging until accessing a proper BS. The above method overcomes the fault that SS may be not access a network and also may be not exit from other network under the condition of requiring SS to access fixed BS in the prior art, and solves access problem when SS is located in the area overlapping among more than two base stations.

  • Patent number: 8126462
    Abstract: In a wireless network, a mobile station is in a serving radio link with a serving base station. A handover is desired so that the mobile station can establish a target radio link with a target base station. When the handover process is initiated, the target base station is alerted about the impending handover by the serving base station. The target base station allocates a radio resource set and provides information on the radio resource set piggy-backed onto an alert response message to the serving base station. The serving base station relays radio resource set piggy-backed onto either a handover request or response message to the mobile station. The mobile station breaks the serving radio link with the serving base station and establishes the target radio link using the radio resource set.

  • Patent number: 8078181
    Abstract: In a method of planning cellular communication networks, at least one cost function indicative of the quality of service rendered by the network is defined which takes into account the quality of service of location-based services rendered by the network. That cost function is preferably based on the concept of dilution of precision and is indicative of the quality of service of voice services, data services and location based services jointly. A system is provided for measuring at least one actual network parameter. The measurements provided by the measurement system are compared with the corresponding parameters as planned with the purpose of locating at least one critical point in the network where inadequate quality of service is being provided. Information items indicative of counter measures to be carried out in the network in order to dispense with at least one critical point are provided.
