Patent number: 7706322Abstract: The disclosed embodiments relate to a method for arranging the transfer of packets between a wireless data transfer device (MS) and a mobile communication network (NW). For transferring packets between the wireless data transfer device (MS) and the mobile communication network (NW), temporary block flows (UL TBF, DL TBF) are formed, and information is transferred in these block flows in one or more packet data traffic channels (PDTCH) either in the first direction from the mobile communication network (NW) to the wireless data transfer device (MS) or in the second direction from the wireless data transfer device (MS) to the mobile communication network. In the method, information about the end of the block flow is set in a packet to be transmitted in a block flow when data transfer has stopped. When the transfer of packets in said first direction has stopped, at least one enquiry message is also sent from the mobile communication network (NW) to the wireless data transfer device (MS).Type: GrantFiled: August 30, 2006Date of Patent: April 27, 2010Assignee: Nokia CorporationInventors: Minna Hautamäki, Arto Leppisaari, Mika Forssell

Patent number: 7636337Abstract: The invention relates to a method for transmitting data for a multimedia broadcast/multicast service (MBMS) from a radio access network of a cellular communication network via a radio interface to mobile terminals located in a radio cell supplied by said radio access network. The radio access network transmits paging messages on a common control channel. It is proposed that a dedicated channel is employed for transmitting the MBMS data, which dedicated channel is allocated in a way that the mobile terminals are able to receive simultaneously paging messages and the MBMS data. The invention relates equally to a corresponding network entity, mobile terminal and communication system.Type: GrantFiled: May 28, 2002Date of Patent: December 22, 2009Assignee: Nokia CorporationInventors: Janne Parantainen, Arto Leppisaari, Harri Jokinen

Publication number: 20090201845Abstract: A method of operating a mobile communication system-supporting data transmission between a mobile station (MS) and a network in a number of different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol PDP data is formatted and unformatted by a sub-network dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP by a protocol identifier transmitted between the network and the mobile station. In order to allow a MS to receive a PTM-M in an IDLE state, a unique protocol identifier is permanently assigned to PTM-M transmissions whilst other identifiers are dynamically assigned to other PDPs by the network.Type: ApplicationFiled: April 22, 2009Publication date: August 13, 2009Inventors: Arto Leppisaari, Jari Pekka Hamalainen

Publication number: 20080151830Abstract: The object of the invention is a method for allocating a radio resource in a packet switched data transmission system, such as GPRS (General Packet Radio Service), which data transmission system comprises terminals and a network. In the method, terminals communicate with the network over the radio interface by using the packet transfer mode, and for communication, a radio resource is allocated to the terminal. For allocating the radio resource, the terminal sends a message to the network. In particular, for allocating a radio resource for the packet switched implementation of a realtime service, a first message is transmitted from the terminal to the network and said first message is received in the network. The network identifies said first message as a radio resource request for the packet switched implementation of a realtime service and allocates to the terminal the requested radio resource for the packet switched implementation of the realtime service.Type: ApplicationFiled: March 12, 2008Publication date: June 26, 2008Applicant: NOKIA CORPORATIONInventors: Arto LEPPISAARI, Juha M.

Publication number: 20070286164Abstract: A method of deleting an item from a user account in a SIP multimedia environment. When an item such as an instant message is to be deleted, a SIP REFER message is transmitted from a user device to delete the item from the user account, with the message including a unique identifier for the item. In response to the transmitted request, an SIP INVITE session is established between a virtual agent and a network-based deleted items location. After the SIP INVITE session is established, the item is transferred from the user account to the network-based deleted items location and is deleted from the user account.Type: ApplicationFiled: March 13, 2007Publication date: December 13, 2007Inventors: Adamu Haruna, Arto Leppisaari

Publication number: 20070250569Abstract: The present invention relates to a method, system, client device, conference server device and computer program product of controlling media composition in a multi-party conversation involving a central control point (50). At a participant (10) of said multi-party conversation, a scope information (SoM) which specifies members of said multi-party conversation is selected and added to a session modifying request. The session modifying request is transmitted to the central control point (50) which initiates a media modification at the specified members in response to the scope information (SoM). Thereby, a client can control whether media modification is applied to the whole conference, selected participants or only between the client itself and the conference server.Type: ApplicationFiled: July 13, 2006Publication date: October 25, 2007Inventors: Jari Mutikainen, Arto Leppisaari

Publication number: 20070226295Abstract: The invention relates to retrieving a conversation or part of the conversation from a database to a terminal. The database contains one or more groups of messages having a first identifier. Each group of messages comprises messages of a conversation. Each message in the group may also have a second identifier. To retrieve the message a group of messages is selected from the database. Then, a message from the selected group of messages is selected and a request is formed. The request is included with the first identifier indicating the selected group of messages. It is also possible that the second identifier indicating the selected message in the selected group of messages is also included in the request. The request is transmitted to a network element controlling the database. The selected message is searched from the database on the basis of the first and the second identifier. If the selected message is found, it is transmitted from the database to the terminal.Type: ApplicationFiled: March 23, 2006Publication date: September 27, 2007Inventors: Adamu Haruna, Arto Leppisaari

Publication number: 20070136475Abstract: Establishing a data communications session involves determining a personal characteristic associated with a user of a terminal. A predetermined criterion for allowing establishment of the data communications session based on the personal characteristic is obtained. A token is embedded in a signaling message used to establish the data communications session. The token represents at least one of the personal characteristic and the predetermined criterion. The signaling message is communicated with a network entity capable of allowing users to establish the data communications session. The data communications session is established via the network entity if the personal characteristic satisfies the predetermined criterion.Type: ApplicationFiled: December 9, 2005Publication date: June 14, 2007Inventors: Arto Leppisaari, Adamu Haruna
