Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

Abstract: In some mobile telecommunications systems reception of calls outside the home network may be very expensive for the called subscriber. For this reason, subscribers are given the possibility to bar incoming calls when roaming outside the home network. On the other hand, when using optimised routing, reception of calls even far from the home network may be very advantageous or even free. Hereby there are no longer any grounds for barring incoming calls. A method is presented in this invention where those network elements can be defined for the subscriber on a location information basis from which incoming calls will be relayed to the subscriber.

Abstract: A telecommunication system comprises a mobile station, or handset, usable by a user, at least one switching centre connectable to the mobile station. The system is arranged such that when an attempt to establish a connection between the mobile station and the switching centre fails, information relating to the cause of the connection failure is provided to the mobile station. The mobile station is able to provide this information to a help centre.

Abstract: A method, a system and a network node for determining services accessible via a subscription. In order to provide access to certain services even when the subscription having an account with a predetermined limit cannot be used for services to be charged from the subscription, at least two sets of services are defined for the subscription, one set of services being used (204) when the predetermined limit is not reached (203) and the other one being used (207) when the predetemined limit has been reached (203). The latter set of services preferably comprises services free of charge.

Abstract: A method (400) for relocating a serving network entity is presented. Before the relocation certain packet data information is transmitted between a terminal and a first network entity (901) at least via a second network entity (902) and via a third network entity (903). The first network entity (901) is connected to the second network entity (902) with a first path (911) and to a third network entity (903) with a second path (902), and the second network entity, which is before the relocation acting as the serving network entity, is connected to the third network entity, which is its peer network entity and after relocation acting as the serving network entity, with a third path (903). The first, second and third paths are separate paths. After the relocation said information is transmitted via the third network entity.

Abstract: System and method for providing a service to a subscriber in a network. A specific network information of a mobile station (1) is provided to a service provider (5) which generates an individual service message on the basis of the provided network information. The provision of the network information may be dependent on a predetermined subscriber condition. Thus, the service message can be transmitted to predetermined subscribers without requiring the subscriber to generate and transmit the specific network information to the service provider (5).

Abstract: The invention relates to a method and apparatus for transmitting group messages in a packet radio network comprising at least one support node and a plurality of group members and at least one defined area. The support node knows the identity of group members in said area. The network comprises broadcast connections and point-to-point connections. The method according to the invention comprises: keeping track of the group members that have not received the group message and determining whether or not their number exceeds a predetermined threshold; in response to a positive determination in the previous step, transmitting the group message over a broadcast connection; and in response to a negative determination, transmitting the group message to the group members over a point-to-point connection.

Abstract: A method for selecting a cell for a mobile station (MS) in a cellular telecommunications network, wherein the mobile station (MS) sends a radio station controller (BSC) measurement reports (6-4) comprising information (61, 631 . . . 63N) about the mobile station's serving cell and its neighbour cells. The mobile station or its subscriber is associated with at least one set of special cells called LSA cells. Information on the set of special cells is transferred to the radio station controller (BSC), and the mobile station (MS) at least participates in the transferring of information, preferably by sending an explicit list of its LSA cells or by including in at least one measurement report (6-4) a flag bit (62, 641 . . . 64N) indicating whether or not the cell in question is a special cell.

Abstract: A communication connection to a second user equipment (UE B) by a first user equipment (UE A) is requested, the request including a specific information element for an identification of UE B, a determination is made (S3) in a database on the basis of the specific information element identifying UE B's location within the communication network, a decision is made (S5, S6) whether UE B is reachable or accepts the communication connection or not, and if the decision is positive, the communication connection is established (S7) between UE A and UE B adapted to perform a packet data communication.

Abstract: The present invention proposes a method for performing a relocation procedure for a user equipment (UE) communicating in a communication network and being movable therein, said communication network comprising at least two serving nodes (SGSN1, SGSN2) of a core network of said communication network, each of which serving nodes being connected to at least one access network controller (RNC1, RNC2) of a access network of said communication network, each of which access network controllers being adapted to perform a communication with said user equipment (UE) within its coverage area, and each serving node being assigned to a respective routing area (RA1, RA2), said method comprising the steps of monitoring (S100) the occurrence of a relocation condition, deciding (S200), whether said relocation condition is an inter serving node relocation condition, switching (S400) the communication from a first access network controller (RNC1) of a first serving node (SGSN1) to a second access network controller (RNC2) of a

Abstract: The invention relates to delivery of short messages to mobile stations and particularly to delivery of short messages in mobility-supporting packet radio networks that use a mobile communications network as an access network, to a dual-mode mobile station in a situation where the mobile station is not reachable in the packet radio network. The object of the invention is to minimize unnecessary signalling. The invention is based on the fact that parameters controlling the network elements are inserted into the signalling messages and a flag indicating the state of the mobile station is inserted into the home location register.

Abstract: A packet switching control system and method are described, for controlling a packet switched connection between a subscriber terminal and an end terminal identified by a connection endpoint identification in a communication network. A subscriber-specific screening list for a plurality of connection endpoint identifications is provided, wherein an subscriber-specific screening control of the packet switched connection is performed on the basis of the screening list. The screening list may contain detection point settings for an IN interrogation so as to provide an interworking function between the IN and the packet network. Moreover, the screening list may include a charging information to thereby define different charging parameters for packet connections to different connection endpoints. This enables the subscriber to define price limits for predetermined connections.
