  • Patent number: 6252868
    Abstract: A communications system in which information is transmitted in successive time slots grouped into a plurality of superframes which are, in turn, grouped into a plurality of hyperframes. A remote station is assigned to one of the time slots in each of the superframes for paging the remote station, each hyperframe including at least two superframes, and the information sent in the assigned time slot in one superframe in each hyperframe is repeated in the assigned time slot in the other superframe(s) in each hyperframe. Each superframe can include a plurality of time slots used for sending paging messages to remote stations, grouped into a plurality of successive paging frames, and the time slot to which the remote station is assigned is included once in every paging frame. Also, each superframe may include time slots comprising a logical channel for broadcast control information and time slots comprising a logical paging channel.

  • Patent number: 5633874
    Abstract: A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.

  • Patent number: 5590133
    Abstract: Apparatuses and mobile stations are described which provide packet data services in TDMA (Time Division Multiple Access) cellular systems, based on providing shared packet data channels optimized for packet data. A first "integrated" embodiment utilizes the current cellular infrastructure to the extent possible consistent with functional and performance requirements. Shared packet data channels in base stations may be provided dynamically determined by demand. A packet data controller in each Mobile services Switching Center controls access to the packet data services. A packet data router in each MSC routes packets to and from the MSC service area. A backbone network interconnects packet data routers and Interworking Functions providing internetworking with external network(s).

  • Patent number: 5577047
    Abstract: A method and system for performing macrodiversity or soft handover in TDMA radiocommunication systems are described. Half rate transmissions are used to provide additional diversity communication channels in systems having insufficient timeslots at full rate. The mobile station can receive the same information from and/or transmit the same information to a plurality of base stations to provide diversity combination and improve transmission quality. The mobile unit assists in making handover decisions by monitoring the signal strength of control channels transmitted by base stations in neighboring cells.

  • Patent number: 5570558
    Abstract: A strengthening member consisting essentially of a bent sheet metal channel with opposing side walls which are provided with stiffening profiling. The profiling forms a uniform pattern of closely spaced indentations (6) separated by intermediate surface regions (7), which pattern extends along each channel wall (2), both the indentations (6) and the intermediate surface regions (7) extending over the entire height of the wall. The channel has a bottom interconnecting the side walls, the indentations having, in a direction parallel to the associated side wall (2), open bases at the bottom and closed apices at upper edges (5) of the walls. The intermediate surface regions (7) have, in a direction parallel to the associated side wall (2), open bases at the upper edges (5) and closed apices at the bottom.

  • Patent number: 5537434
    Abstract: A communication system having a frequency hopping scheme which provides an improved initial synchronization in mobile stations of control channels. Special synchronization bursts are inserted into the hop sequence of the control channels which, when decoded, give the mobile station the hop sequence to follow for the control channel.

  • Patent number: 5295152
    Abstract: A method and system for increasing the capacity of radiotelephone communication systems by eliminating interference to communication traffic caused by random access bursts from unconnected mobile station are disclosed. Access slots are provided in CDMA signals by interrupting other communication traffic of mobile stations using the same frequency at periodic intervals. This allows mobile access bursts to be received at a base station without interfering with other traffic.

  • Patent number: 5039564
    Abstract: A tearing strip of the delaminating type intended for attachment to opposite insides of a package.The strip has such a layer structure that, relative the inside of the package, it has a melted-together seal while internally the strip has layers which are not fully melted together.The strip comprises a central, strong layer and a first and second layer arrangement.The first layer arrangement has a well reproducable, high seal strength relative the central layer. However, the second layer arrangement is "peelable" relative the first layer arrangements or more likely internally between two layers. In contrary the second layer arrangement has a well reproducable, high sealing strength relative the inside of the package.
