  • Patent number: 7200125
    Abstract: In a wireless communications network, different service levels can be subscribed to by users of mobile stations for packet-switched communications, such as electronic mail, web browsing, text chat, packet-switched voice communications, and so forth. In one arrangement, two different levels are defined. For a first level, when there is no more data to send over a wireless interface between a mobile station and a wireless access system, a logical connection between the mobile station and wireless access system is released. However, at a second level, the logical connection between the mobile station and the wireless access system is not released until after a predetermined timed period from when a send buffer becomes empty, with the send buffer containing data for sending over the wireless interface. A benefit of releasing the logical connection after some predetermined wait period is that the delays associated with establishing another logical connection are reduced.

  • Patent number: 7139370
    Abstract: A communication system includes various terminals that are capable of establishing call sessions over a data network. Each of the terminals includes a display in which hyperlinks can be presented. User selection of the hyperlinks is communicated to one or more application routines, which generates requests based on information (e.g., uniform resource locators) associated with the selected hyperlinks. The requests cause generation of call requests over the data network to establish call sessions between terminals.

  • Patent number: 6907228
    Abstract: A mobile communications network includes a plurality of cells and cell sectors in each cell. Carrier frequencies for carrying beacon control signaling, such as a broadcast control channel (BCCH), are assigned from the entire band of available carrier frequencies. The same carrier frequencies are assigned to carry traffic channels. This arrangement enables the use of one carrier frequency to communication beacon control signaling in one cell segment, while also allowing the use of the same one carrier frequency to communicate bearer traffic in another cell segment, thus affording substantial increases in network capacity that has heretofore not been possible in networks in the absence of significant infrastructure buildout or modification.

  • Publication number: 20020082033
    Abstract: A wireless communications system includes a mobile station and a base station system that are capable of communicating on the wireless links (uplink and downlink). The mobile station is capable of establishing a logical connection, such as a temporary block flow, on the uplink, while the base station system establishes a logical connection on the downlink. When either the mobile station or the base station system detects end of data transmission, a predetermined wait period is started during which the mobile station or base station system does not start a procedure to release the logical connection on the uplink or downlink.
