Patent number: 6252868Abstract: 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.Type: GrantFiled: January 11, 2000Date of Patent: June 26, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: John W.

Patent number: 5633874Abstract: 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.Type: GrantFiled: October 31, 1994Date of Patent: May 27, 1997Assignee: Telefonaktiebolaget LM EricssonInventors: John W.

Patent number: 5590133Abstract: 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.

Patent number: 5570558Abstract: 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.Type: GrantFiled: May 24, 1994Date of Patent: November 5, 1996Assignee: AB VolvoInventor: Bengt Persson

Patent number: 5295152Abstract: 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.Type: GrantFiled: April 10, 1992Date of Patent: March 15, 1994Assignee: Telefonaktiebolaget L M EricssonInventors: Bjorn Gudmundson, Bengt Persson

Patent number: 5039564Abstract: 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.Type: GrantFiled: July 5, 1989Date of Patent: August 13, 1991Assignee: AB Akerlund & RausingInventor: Bengt Persson
