Publication number: 20010019542Abstract: A method is disclosed for improving the efficiency of the packet data channel by providing means for interrupting transmissions from or to a first mobile station so as to allow a short message to be communicated between the communication system and a different mobile station. The packet channel feedback information includes several flags: Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.Type: ApplicationFiled: February 5, 1997Publication date: September 6, 2001Inventors: JOHN DIACHINA, JOHAN LARSSON, ALEX K.

Patent number: 6028854Abstract: Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate. Moreover, FACCH information need only be transmitted in the master channel.Type: GrantFiled: October 15, 1996Date of Patent: February 22, 2000Assignee: Telefonaktieboalget LM EricssonInventors: Alex Krister Raith, James Ragsdale, John Diachina

Patent number: 6016428Abstract: A method and device are provided for storing and maintaining parameters associated with activities relating to a first channel while a mobile station is camped on or uses a second channel. More specifically, when a parameter indicates that activities are to be executed, the mobile station returns to the first channel to execute the actions associated with the parameter. For instance, parameters associated with a DCCH may be stored when the mobile station moves from the DCCH to a packet data channel (PDCH). When a parameter indicates that activities are to be executed, the mobile station may then return to the DCCH from the PDCH and execute the actions associated with the parameter. Since the mobile station returns to the DCCH for the actions rather than staying on the PDCH, the mobile station is activated from a system perspective, on both channels.Type: GrantFiled: October 18, 1995Date of Patent: January 18, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: John Diachina, Raymond C.

Patent number: 5987019Abstract: Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Bandwidth in the second (or third) time slot can be used to carry information in a fast out-of-band channel (FOC). The FOC may provide information relating to the same connection as the payload or data field in that time slot, e.g., a service type identifier which informs the mobile or base station of the type of information (e.g., voice, video or data) being conveyed in the payload. Alternatively, the FOC information may be associated with a connection or connections which are different from that supported by the payload or data field containing the FOC.Type: GrantFiled: October 15, 1996Date of Patent: November 16, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Alex Krister Raith, James Ragsdale, John Diachina

Patent number: 5835860Abstract: Methods for operating and administering mobile station user groups in a wireless communications system. In one embodiment, a user group identification code is assigned to a plurality of mobile stations to form a user group, wherein the number of mobile stations in the user group is less than the total number of mobile stations in the entire communications system, and wherein the user group identification code is distinguishable from a unique mobile station identification code associated with each mobile station in the user group. A page message from the system to the user group is transmitted using the user group identification code when a terminating call to the user group is requested. A user group specific page indication is then generated at the mobile stations indicating to a user of each mobile station that the page message has been received. A page response message is then transmitted to the system from mobile stations whose users acknowledge the page indication.Type: GrantFiled: March 18, 1997Date of Patent: November 10, 1998Assignee: Ericsson Inc.Inventor: John Diachina

Patent number: 5806007Abstract: A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.Type: GrantFiled: October 18, 1995Date of Patent: September 8, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Alex Krister Raith, Lars Bilstrom, John Diachina, Raymond C.

Patent number: 5729531Abstract: A method for reassigning mobile stations a new phase within a channel is disclosed. In a communication system, a plurality of mobile stations attempt to communicate on a limited number of channels. The invention first uses a general allocation method to approximately evenly distribute the mobile stations on the available channels. After a mobile station begins active communication on the system, a second allocation method is used to change the phase of some mobile stations on a channel which has become heavily loaded. In addition, a message can also be sent to mobile stations assigned to but not yet actively communicating on the heavily loaded channel indicating that the mobile stations should change to a new channel.Type: GrantFiled: October 18, 1995Date of Patent: March 17, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Alex Krister Raith, Alan Eric Sicher, Lars Billstrom, John Diachina, Raymond C.
