Abstract:
PROBLEM TO BE SOLVED: To provide a hybrid protocol for supporting communication with a plurality of networks. SOLUTION: A system and techniques include: monitoring a first network in accordance with a first air interface; receiving a message from a second network via the first air interface; and linking the second network with a second air interface, which is different from the first air interface. As a radio communication device advances to a geographically-different target area, various techniques for registering and linking for maintaining the connectability with both the networks are also under study.

PROBLEM TO BE SOLVED: To provide a hybrid protocol for supporting communications with multiple networks. SOLUTION: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.

PROBLEM TO BE SOLVED: To determine use of receive diversity in a mobile station. SOLUTION: A control system 210 determines a demand level about usage of a communicating resource. A sender transmits a message, which shows the usage of receive diversity in the mobile station based on the determined demand level. After receiving one channel, the receiver 200 determines a transmitting power level of the channel for being at a lower or upper transmit power level limit. Based on the determined transmitting power level, the control system 210 controls the receive diversity by choosing the number of receiver chains 290. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To determine an effective use of reception diversity, and to reduce power consumption. SOLUTION: A control system 210 determines a demand level for use in a communication resource. A transmitter communicates with a message indicating the use of the reception diversity at a mobile station based on a determined demand level. In another aspect, a receiver 200 receives one channel and determines a transmission power level of the channel at a lower-limited transmission power level or an upper-limited transmission power level. The control system 210 controls the reception diversity by selecting the number of receiver chains 290 based on the determined transmission power level. In another aspect, the receiver 200 receives one channel and determines one channel condition of the channel and the duration of the channel condition. The control system 210 selects the number of the receiver chains 290 based on the determined channel condition and the duration. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. SOLUTION: A receiver receives a first broadcast controller identification from a first base station 101, and a second broadcast controller identification from a second base station 160. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services. COPYRIGHT: (C)2010,JPO&INPIT
