Abstract: When a mobile station has moved from a network area controlled by a first radio network controller (RNC) to a network area controlled by a second RNC, the utilisation of transmission links in the radio access network is optimized and the transmission delay between the controlling RNC and the radio interface is minimized by relocating the entities which control the connections of the mobile station from the first RNC to the second RNC. Such controlling entities may be, for example, the macrodiversity combining function, radio resource control block, and associated user plane entities.

Abstract: The invention relates to a mechanism for providing location information regarding mobile terminals, especially regarding WLAN terminals. In order that the known mechanism for locating users of a mobile cellular network could be utilized for locating WLAN terminals, a location service request concerning a WLAN terminal is received and routed by the same network elements that receive and route location service requests concerning users of a mobile cellular network. However, in the case of a WLAN terminal the location service request is diverted to a predetermined network element, where the access point currently serving the WLAN terminal is identified. The location information corresponding to the said access point is then determined, and the location information is returned as the location of the terminal. The location of the serving WLAN access point thus represents the location of the WLAN terminal.

Abstract: A signalling method in a wireless digital telecommunication system between a base station and a terminal, where the signals between the base station and the terminal are generated from bursts comprising symbols, the bursts comprising a known training sequence. The symbols are used for generating a second training sequence of the same length as the known training sequence and a burst comprising said training sequence to be used for transmitting signalling messages. The number of training sequences used can be restricted to two, whereby conventional user data is sent in the burst comprising the known training sequence and information deviating from the conventional user data is sent by the burst comprising the second training sequence, and the stealing symbols in the burst can be used for specifying a signalling message to be transmitted.

Abstract: The invention comprises a method for establishing a signaling connection with a mobile station, which method is particularly applicable to third-generation mobile communications networks. A database is created at a node of a mobile communications network, and a mobile station connected with the network sends to said database information about all its subscriber identities (403). In the database, information is added (404) to the subscriber identity information which may be useful when said mobile station is paged (410, 411). Such contactability information includes e.g. the mobile station's location information, information about existing signaling connections and information about the primary paging channel monitored by the mobile station. The contactability information is updated according to changes detected in the status of the mobile station (406). The database will be discontinued for a mobile station that has had no connections for a predetermined time.

Abstract: A method (and corresponding equipment) for use in reauthentication—after a first, full authentication by a first authentication server (23a)—of a communication session involving the exchange of information between a terminal (21) and a server (24), the method including: a step (11) in which the first authentication server (23a) and other authentication servers (23b) are each assigned a respective unique realm name; and a step (13) in which during authentication between the terminal and the first authentication server (23a), the first authentication server (23a) transmits to the terminal (21) a reauthentication identity including the unique realm name assigned to the first authentication server. Then, later, during reauthentication, to make possible that the reauthentication is performed by the same authentication server (23a) as performed the full authentication—i.e. by the first authentication server (23a)—the reauthentication identity is included in a request for reauthentication.

Abstract: The invention relates to methods for transmission of signalling data in cellular telecommunication networks. According to the invention, multiple radio bearers can be allocated for transferring signalling traffic, but all higher layer signalling is in any case taken through the RRC protocol. In the inventive method, MM and higher layer messages are sent using RRC DIRECT TRANSFER messages, but a separate RLC entity is set up for RRC DIRECT TRANSFER messages. In various embodiments of the invention, separate radio bearers can be set up for individual CN domains and/or upper layer protocols and/or for a group of RRC messages.

Abstract: A method for duplex telecommunication connection in radio connections is based on a frame-structured interactive communication and a radio system where the frame-structured interactive communication is performed in the radio connections. A means is provided for improving the use of channel resources in implementation of interactive telecommunication connection by providing an FDD connection with one or more TDD dimensions. A full-duplex frequency band is time-duplexed into two or more sub-bands in which interactive communication takes place substantially independently. Transmissions in different transmission directions in each sub-band occur at different times, but simultaneous transmission can occur in different sub-bands in different transmission directions. The message is received entirely in one transmission direction before it needs to be responded to in another transmission direction in a particular sub-band.

The method includes storing the identification (SSID) of the at least one other network (visited PLMNs 1-3 and home PLMNs 4 and 5) in the user equipment; transmitting from the user equipment a request for connection to one of the at least one other network, which includes an identification of at least one of the at least one other network, to the wireless access network; and in response to the wireless access network receiving the identification, the user equipment is connected to the identified at least one other network through the wireless access network.

Abstract: The present invention relates to a method and system for establishing a connection via an access network (30) communicating with at least one user terminal, and at least one backbone network (100) comprising at least user terminal authentication and authorization means (50) and at least one user data processing node (60, 62), wherein the connection of a user terminal (10) is authenticated to the access network (30) and one of the at least one user data processing nodes (60, 62) is selected based on a selection information transferred in the authentication signaling. Then, a tunnel parameter information of the selected user data processing node is signaled to the access network (30) and a tunnel connection is created between the access network (30) and the selected user data processing node (60) based on the tunnel parameter information.

Abstract: The present invention relates to a method, system and device for providing access from a terminal device (1) to a second access network (8). To achieve this an access network device (3) belonging to an first access network (12) stores a second access network information comprising information of second access network(s) (8) accessible from the first access network (12). Communication means between the terminal device and and the first access network are established and the second access network information is delivered to the terminal device (1). The terminal device (1) accesses the second access network (8) via the first access network (12). The accessing is done based on the second access network information delivered to said terminal device (1). Thereby, service functions of the second access network, e.g. UMTS services, can be distributed via any other access network and existing broadband or high-speed access networks can be implemented in new cellular network structures.

Abstract: According to the method of the invention, connections are divided into at least two different connection classes according to their requirements for transmission delay. The control system of the base station subsystem maintains a record of the transmission needs of the users logged in different categories and based thereon divides the available radio resources into slots of suitable capacity. For connections with stringent requirements for transmission delay, circuit-switched connections are allocated with a bandwidth which can be controlled dynamically. Then from the resource pool still unassigned after the resource allocation to the circuit-switched connections, a sufficient amount of resources are allocated on a time-limited basis allocation for each allocation period to connections having a higher tolerance for delay so as to accomplish transmission, e.g. of a given amount of data.

Abstract: 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.

Abstract: The present invention relates to a communication system and a method for the same. In the method simultaneous circuit switched and packet switched connections are established between a user equipment and a first element of the communication system. A predefined event is monitored for after initiation of a procedure for handing the circuit switched connection over from the first element to a second element of the communication system. The event is defined to indicate a need for release of resources reserved by the packet switched connection. Subsequent to detection of the event, resources reserved by said packet switched connection at the network side of the system are released.

Abstract: The invention relates to a method of arranging roaming in a telecommunications system comprising a local network, at least one public land mobile network, and a terminal equipment. In the telecommunications system, public land mobile network identifiers and network element identifiers linked therewith are defined. These public land mobile network identifiers and the network element identifiers linked therewith are transmitted to the terminal equipment. The terminal equipment selects a public land mobile network by means of a comparison of the received public land mobile network identifiers and public land mobile network identifiers stored in the terminal equipment. Access is arranged for the terminal equipment via the local network to the network element determined by the network element identifier linked with the identifier of the selected public land mobile network.

Abstract: A method and system for transmitting a position information from a mobile terminal of a mobile communication network via a network element to a network node, wherein a control information indicating the requirement of a position information of the mobile terminal at the network node is set in the radio interface message. This control information is checked at the network element as to whether a position information has to be forwarded or not. The position information is determined at the network element and may be combined with a higher layer information so as to generate a complete higher layer information to be forwarded to the network node. Thereby, a position information can be supplied to the network node without substantially increasing overhead and processing power required for the radio interface message.

Abstract: The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver requests, if necessary, retrasnmissions of the originally sent transmission unit, until the quality of the combined transmission unit formed of the originally sent transmission unit and its retransmitted copies corresponds to the predetermined quality level. The signal is not detected until after this. If the packet is interleaved and encoded and it is found out that the packet is not faultless, retransmissions of the transmission units of the packet that are of the poorer quality are requested. The invention also relates to a mobile communications system implementing the method of the invention.

The invention also relates to a mobile communications system implementing the method of the invention.

Abstract: In order to control the use of physical radio resources, the physical radio resources are divided into chronologically consecutive frames (14), so that a frame contains slots (16, 17, 18) of various sizes, which slots represent a given share of the physical radio resources contained in the frame and can be individually allocated to different radio connections. The first dimension of a frame is time and the second dimension can be time, frequency or code. In the direction of the second dimension the slots represent various sizes, and a given first integral number of slots of the first size can be modularly replaced by another integral number of slots of another size. A certain number of consecutive frames form a superframe (19), in which case frames with corresponding locations in consecutive superframes are equal in slot division and allocations, if the data transmission demands do not change. Changes in the state of occupancy of the slots are possible at each superframe.
