  • Patent number: 7844272
    Abstract: Provided is a method for preventing excessive handovers in a mobile communication system. In the method, a periodic measurement report message is transmitted from a mobile terminal to a network. The network determines, on the basis of the measurement report message from the mobile terminal, whether a handover of the mobile terminal needs to be performed. Thereafter, the network transmits a Handover_Command message to the mobile terminal if the handover of the mobile terminal needs to be performed. Upon receipt of the Handover_Command message, the mobile terminal performs a handover to a target handover cell according to the Handover_Command message, transmits a Handover_Complete message to the network, and transmits a first measurement report message including neighboring cell information set to Null from the mobile terminal to the network after the transmission of the Handover_Complete message.

  • Patent number: 7835739
    Abstract: A method and apparatus are provided for excluding ineffective Inter System Page (ISPAGE) attempts in a mobile switching center (MSC). The present invention involves determining a time difference between an arrival time of an ISPAGE message and a time of a last seen activity of a mobile communications device. The ISPAGE message is dropped if the time difference exceeds an optimum time cutoff value. Also, the present invention provides a technique for determining the optimal time cutoff value by determining the fraction of all ISPAGE messages that may be dropped, and the fraction of all ISPAGE messages that produce page respones that will be admitted as a function of the optimal cutoff time value.

  • Patent number: 7801509
    Abstract: A computer-readable recording medium storing a data communication program capable of transmitting desired data quickly. The mobile terminal (computer) has the following functions: A data accumulating section accumulates accumulation data to be uploaded to a server 7. A transmission data-generating section generates transmission data that is to be transmitted to the server for making the inquiry and has the accumulation data added thereto. A determination section determines whether or not the mobile terminal is in a state in which the transmission data can be transmitted to the server. A communication scheduler permits a data communication section to transmit the transmission data to the server based on the result of determination of the determination section. The data communication section transmits the transmission data to the server in response to permission of the communication scheduler.

  • Patent number: 7715787
    Abstract: A method of transmitting subpackets in a mobile communication system using at least one frequency carrier is disclosed. More specifically, the method comprises receiving a first broadcast subpacket from a base station (BS) at a first time slot on a first frequency carrier, and receiving at least one subsequent broadcast subpacket from the BS via at least one relay station (RS) at a second time slot on a second frequency carrier, wherein information of the first broadcast subpacket and the subsequent broadcast subpacket are the same.

  • Patent number: 7689162
    Abstract: A process is described to build physical layer frames with a modcode adapted to the signal quality of a destination terminal. Data packets assigned to the same modcode may be sent in the same frame, although packets associated with higher modcodes may be used to complete a frame before switching to the applicable higher modcode for construction of subsequent frames. After an interval, the order of progression is restarted with an out of order packet above a threshold age. Flow control filtering mechanisms and a variable reliability margin may be used to adapt dynamically to the current data traffic conditions.

  • Patent number: 7672283
    Abstract: Computer implemented techniques for detecting the presence and identity of unauthorized wireless devices (“UWD”) on a network. The technique is capable of detecting the presence and existence UWDs irrespective whether the UWDs implements encryption in their communication. Furthermore, it is unnecessary for the computer-implemented method to access the management console of a wireless access point for the purpose of determining the identity of the wireless client devices that currently employ the access point to accomplish the wireless communication. The computer-implemented method also does not require any software agent to be installed on the wireless client devices for the purpose of detecting unauthorized wireless communication.
