Patent number: 9462443Abstract: In a multi-access environment, applications with high priority can temporarily, when needed, occupy parts or even complete resources from at least one of the accesses in a certain geographical area radio access can be secured for such applications. An area consisting of a number of cells is created In such an area, an application having high priority can have guaranteed resources on one pre-determined access while other “ordinary” traffic is temporarily directed to the other access(es) even if that may result in a lower Quality of Service (QoS) in that particular area.Type: GrantFiled: April 17, 2007Date of Patent: October 4, 2016Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventor: Dalibor Turina

Patent number: 6668175Abstract: A method and an apparatus for providing radio access bearer services for different applications in a network having a core network and a radio access network through radio access bearers between the networks are presented. One or more session traffic flows being sent by an application are identified, the identified session is characterized in the form of parameters needed for the determination of the one or more radio access bearers. The characterized parameters are converted into radio access bearer attributes. One or more radio access bearers defined by the attributes are requested and established. Each session is mapped onto a correct radio access bearer established upon receiving the request. The one or more radio access bearers are released when no longer needed.Type: GrantFiled: July 14, 2000Date of Patent: December 23, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Magnus Almgren, Christer Johansson, Håkan Olofsson, Dalibor Turina, Zsolt Haraszti, Magnus Hartman, Niclas Lindberg

Patent number: 6501745Abstract: A packet data communication system uses an USF (Uplink State Flag) transmitted on the downlink and interleaved with downlink data, to schedule traffic on the uplink for one or several mobile users utilizing the same physical channel. The USF indication is made variable and defined in the control signaling at setup of a packet transmission. An USF indicates to a mobile that one or several consecutive radio blocks is reserved for uplink transmission from a specific mobile. The mobile does not have to receive the USF during the remaining period defined by the number of radio blocks scheduled. The solution is especially advantageous in combination with adaptive antennas when all radio blocks on the downlink transmissions do not have to be broadcast to all users on a certain channel.Type: GrantFiled: December 1, 1998Date of Patent: December 31, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Dalibor Turina, Bengt Persson

Patent number: 6400954Abstract: A radiocommunication system supports high throughput rates over an air interface. An access network interface, e.g., between a base station and base station controller, conveys information between the base station and the rest of the terrestrial system. Techniques are provided to adjust transmission rates over the air interface based on loading of the access network. Techniques are also provided to control bandwidth allocation over the access network interface and distribute call blocking/delay percentages when there is an imbalance between the capacity of the air interface and the access network interface.Type: GrantFiled: May 15, 1998Date of Patent: June 4, 2002Assignee: Tlelefonaktiebolaget LM Ericsson (publ)Inventors: Farooq Khan, Dalibor Turina, Magnus Frodigh

Patent number: 6097717Abstract: The present invention concerns a process in a radio communication system which is arranged for packet data transmission according to a message-synchronized ALOHA protocol with reservation. Mobile stations in the system are arranged to send access requests to a base station during a reservation phase in a mobile radio system which uses this protocol. The base station is arranged to receive and comply with the access request from a first mobile station by sending thereto a channel reservation message (2) comprising a channel reservation (3). The base station is further arranged to receive access requests from at least a second mobile station for which channel reservation momentarily cannot be carried out. According to the process of the invention an access request received from the second mobile station is confirmed when channel reservation cannot be carried out in the usual manner.Type: GrantFiled: April 28, 1998Date of Patent: August 1, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Dalibor Turina, Lars Billstrom

Patent number: 6031832Abstract: A communications system is provided that uses a multiple access packet reservation type of protocol. The physical channels required for the packet transfers are specially allocated to one mobile station (referred to as a "VIP MS"). The VIP MS has the exclusive priority to use these allocated physical channels for packet data as needed. Consequently, the VIP MS always has the negotiated bandwidth available for the packet transfers. Furthermore, since the VIP MS is given the highest exclusive priority to access these physical channels ("VIP priority"), by allocating a reserved random access channel dedicated to the VIP MS (e.g., on one allocated uplink channel), the variable random access delays experienced by prior systems no longer exist Since the VIP MS is always scheduled first for transmissions on the downlink, and reserved access is provided for the VIP MS on the uplink, only a constant delay period for the uplink and downlink is involved.Type: GrantFiled: November 27, 1996Date of Patent: February 29, 2000Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Dalibor Turina

Patent number: 5931964Abstract: The present invention relates to a method and an arrangement for channel allocation in a radio communication system in which data is transmitted between two stations over two or more radio channels. Data is communicated as packets which are divided into blocks while the transmission follows a protocol for automatic re-transmission of data that have been erroneously transmitted. In accordance with the proposed method, channels for re-transmission are allocated with respect to a transmission parameter which has been created at a previous transmission and which is based upon information of the result of said previous transmission. The transmission parameter is aimed to ensure that re-transmission is performed via those channels which have the highest probability of transmitting data correctly. The channels which had the highest transmission quality in said previous transmission are expected to have the highest transmission quality also by re-transmission.Type: GrantFiled: February 14, 1997Date of Patent: August 3, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Per Johan Beming, Dalibor Turina

Patent number: 5784362Abstract: Automatic repeat request (ARQ) functionality in a cellular mobile packet data communication system using a reservation slotted-ALOHA protocol is provided by assigning a temporary frame identity (TFI) to each data frame transmitted to or from a mobile station. The assigned TFI is unique among concurrent frame transfer sequences in a cell, and may be assigned based on information in a data frame sent to the mobile station or based on information in a channel reservation message that precedes the data frame sent to the mobile station. The TFI may also be assigned based on information in a channel reservation message that precedes a data frame sent from the mobile station, and the TFI assigned is unique among concurrent frame transfer sequences in a cell. The TFI is included in every block belonging to a particular frame, a block being the unit of data on which ARQ is based. A partial data frame to be retransmitted in case of a transmission error contains only the blocks determined by the ARQ protocol type (e.g.Type: GrantFiled: April 17, 1995Date of Patent: July 21, 1998Assignee: Telefonaktiebolaget LM EricssonInventor: Dalibor Turina
