A method for providing an Internet service with advertisement is provided. First, a computing device installs an ad-playing application and runs the ad-playing application to request a telecommunication network for a connection to the Internet. Then, the telecommunication network establishes the connection for it and transfers advertisement to the computing device. Then, the ad-playing application plays the advertisement on the screen of the computing device. Last, the telecommunication network disconnects the connection when the advertisement is not played on the computing device. Moreover, A system for providing the Internet service with advertisement is disclosed in the specification.

A method for a mobile communication device to select a charging scheme is disclosed. The method can be implemented by a mobile communication device connecting to one of a plurality of foreign networks. The mobile communication device builds a connection with a home network through the connected foreign network. The home network sends charging scheme information to the mobile communication device by a communication method and the mobile communication device sends information of a selected charging scheme of a selected foreign network to the home network by the communication method. The mobile communication device then obtains services of the home network with the selected charging scheme through the selected foreign network.

A search method of a roaming service for registering a mobile station to a network service is provided. The search method comprises the step of searching for a registered public land mobile network (RPLMN) and registering to the RPLMN when the record of the RPLMN is existing and the RPLMN is found and the location registration is necessary. When the record of RPLMN is not existing, or the mobile station can not find an available base station, or the location registration is unsuccessful, or a scan timer expires, the steps of updating an available public land mobile network (PLMN) list and performing a location registration according to the available PLMN list is performed. The step of updating the PLMN list further comprises sorting the available PLMNs according to an order of preferred PLMNs corresponding to a current location of the mobile station, or according to a data transfer speed.

A search method of a roaming service for registering a mobile station to a network service includes searching for a home public land mobile network (HPLMN) when the mobile station is first switched on or recovering from lack of service, or sorting an available public land mobile network (PLMN) list, or using a scaling method to obtain a temporary timer period for a periodic search. Sorting the available PLMN list includes sorting according to a location-based order of preferred PLMNs, or sorting according to a data transfer speed supported by each PLMN. The scaling method includes examining a change ratio in the available PLMN list, or a data transfer speed of the RPLMN, or a status of Mobile Country Code (MCC) in order to obtain the temporary timer period.
摘要:
A method for allocating utilization of multiple carriers in a wideband CDMA transmission system first determines the carrier utilization/interference levels for each of the multiple carriers. Based on the carrier utilization/interference level, carrier assignments are allocated on an unequal basis. The allocation of the carrier assignment biases the selection of the carriers away from higher utilized/interfered carriers. An apparatus for implementing the method is also described.
摘要:
A base station assembles a frame including information bits at a vocoding rate for downlink transmission over a traffic channel as channel bits at a channel rate. The base station places at least one rate-indicating bit at a beginning of the frame for indicating the vocoding rate. The mobile station evaluates the downlink transmission with consideration of the vocoding rate indicated by the at least one rate-indicating bit. The mobile station can determine the vocoding rate by decoding the beginning of the frame to permit power control in less than one frame duration from initial receipt of the frame at the mobile station.
摘要:
Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone. Other aspects of the invention reduce unnecessary searching for a new frequency and decrease the likelihood of “ping-ponging” from a current frequency to a new frequency by providing additional checks in the handoff process. For example, receive power and pilot signal-to-noise measures may be generated at a mobile station for both current and new frequencies. The mobile station then continues to operate at the current frequency as long as certain predetermined threshold conditions based on the measures are satisfied.
摘要:
The present invention is a method for efficiently utilizing spectrum resources belonging to a wireless communications system in the presence of data channels through a discontinuous data transmission technique. The discontinuous data transmission technique involves the transmission of a flag over a control channel (or some other communication channel) in frame f, wherein the flag would indicate to an intended recipient that a transmitter has a data frame to transmit to the recipient in some future frame f+q. In an embodiment, the transmitter would subsequently transmit the data frame over a data channel (or some other communication channel) in frame f+q if the flag indicated that the data frame was ready to be transmitted. In another embodiment, the transmitter would not transmit the data frame unless the recipient has indicated (via another flag) that the recipient is ready to receive the frame of data from the transmitter.
摘要:
A method for extending a cell radius or access range of a base station without incurring ASIC correlator re-design. This is accomplished using a modified timing protocol that will cause signals transmitted by mobile-telephones positioned beyond the limitations of the ASIC correlator bit limitation to be received within a search window so the signals may be detected and demodulated. In one embodiment, the modified timing protocol incorporates a timing advance technique in which the base station transmits its signals at an advanced time before frame boundaries such that signals transmitted by out-of-range mobile-telephones can be received within a search window beginning at a frame boundary and spanning a time interval corresponding to the ASIC correlator bit limitation. In another embodiment, the modified timing protocol incorporates a shifted search window that begins at an advanced time after a frame boundary and spans a time interval corresponding to the ASIC correlator bit limitation.
