Patent number: 7106694Abstract: The invention concerns the control of connections in cellular telecommunication systems. According to the invention, the available radio resources are controlled by allowing only certain conbinations of transport formats to be used by a single user. The inventive method restricts the combinations of bearer bit rates which can be used, without strictly limiting some bearers from using highest bit rates. This inventive approach allows flexible overall control of radio resources, while retaining the possibility of bearers to select between different bit rates.Type: GrantFiled: November 5, 1999Date of Patent: September 12, 2006Assignee: Nokia Networks OyInventors: Janne Salonen, Mikko Rinne, Harri Honkasalo, Jaakko Rajaniemi, Kalle Ahmavaara

Patent number: 7031701Abstract: The invention is directed to a method for controlling delays in a cellular telecommunications network. The delay control method according to the invention is based on a hierarchical structure of delay controlling entities, which preferably communicate only with entities directly above or below them in the hierarchy. In the downlink direction, an entity receiving data, such as a base station or a splitting unit, sends a timing report to the entity sending the data if the data is received too early or too late, whereafter the sending entity may adjust the sending time of data. The same reporting and adjusting process may be repeated through all levels of the control hierarchy, resulting in a collective control of delays from the top of the hierarchy, for example from a RNC, to the bottom, for example to a base station.Type: GrantFiled: March 31, 1999Date of Patent: April 18, 2006Assignee: Nokia Networks OyInventors: Kalle Ahmavaara, Sami Kekki

Patent number: 7027417Abstract: In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.Type: GrantFiled: February 23, 2000Date of Patent: April 11, 2006Assignee: Nokia CorporationInventors: Markku Verkama, Kalle Ahmavaara, Timo Perälä, Jari Hartikainen

Patent number: 6993340Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel of independent singalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling.Type: GrantFiled: February 15, 2000Date of Patent: January 31, 2006Assignee: Nokia Networks OyInventors: Mikko J.

Patent number: 6898433Abstract: A method for indicating a mobile station's (MS) location. A first radio network controller, RNC, acts as the mobile station's serving RNC (SRNC), for reporting the mobile station's location to the core network (CN). A second RNC acts as the mobile station's drift RNC (DRNC), for maintaining a radio connection with the mobile station. In response to fulfillment of at least one criterion in a first set of criteria, the mobile station (MS) sends location information about its location to the second RNC (DRNC) which forwards the location information to the first RNC (SRNC) for reporting to the core network (CN). There is also a second set of criteria for transforming the location information. In response to fulfillment of at least one criterion in the second set, the first RNC (SRNC) sends falsified information about the mobile station's location to the core network (CN).Type: GrantFiled: April 26, 2000Date of Patent: May 24, 2005Assignee: Nokia Networks OyInventors: Jaakko Rajaniemi, Kalle Ahmavaara, Heikki Einola, Juha Bäck, Tony Hulkkonen, Serge Haumont

Patent number: 6842445Abstract: An automatic repeat request mechanism (such as Type II/III hybrid ARQ) which includes (soft or hard) combining of initially transmitted and retransmitted versions of a packet, is provided for retransmission of erroneous packets. According to the present invention, in association with each retransmission, there is outband signaling from a transmitter to a receiver that unambiguously indicates when, e.g. the exact time or physical location, the first transmission of the packet was carried out, so that it is possible to combine the retransmitted version with the previous version(s) of the packet. Soft combining requires that the initial packet and the retransmitted packet be identical. In an embodiment of the invention, in order to overcome this problem, the information that needs to be changed between the initial transmission and the retransmission(s) of a packet is sent outband with other outband signaling information.Type: GrantFiled: December 13, 2000Date of Patent: January 11, 2005Assignee: Nokia CorporationInventors: Kalle Ahmavaara, Jukka Vialén, Fabio Longoni, Esa Malkamäki

Publication number: 20040252660Abstract: When a new connection is set up between a mobile station and a cellular telecommunications network, the starting frame of the new connection is selected using a simple rule so that the starting times of the interleaving periods of all the presently active connections between the mobile station and the cellular network are periodically aligned, thereby substantially simplifying the handover process. In addition, the length of the interleaving period can be set such that the periodic alignment is more frequent.Type: ApplicationFiled: July 8, 2004Publication date: December 16, 2004Inventor: Kalle Ahmavaara
