Abstract: The present invention relates to a method and system for locating a mobile terminal addressed in a location service request by an overlay identity. A database (60) is accessed to obtain a first routing information of the mobile terminal based on the overlay identity, and the first routing information is then used to access a sub-scriber database (40) in order to derive a second routing information and a cellular identity of the mobile terminal (10), based on which a location service of the cellular network is initiated. Thereby, a LCS clients of the overlay system (e.g. IMS) can be supported in current LCS services to enhance their functionality.

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: The invention is directed to a instant messaging method and communication system comprising one or more network elements, wherein a connection from one to another network element can be established using a protocol which allows the sending of one or more messages from the one to the another network element as part of one or more protocol words. The protocol includes a protocol portion allowing a network element to specify whether or not the message is to be stored in case it cannot be promptly delivered to the another network element. The protocol portion preferably is part of the protocol header. The protocol may be a Session Initiation Protocol (SIP), and the message can be contained in an Invite request sent from the sending equipment to the receiving equipment.

Abstract: A mechanism and method for initiating a packet-based service session in a public mobile communication system, especially a service session for a group of users are disclosed. In order to accomplish a service initiation even if the terminals of the users are in a disconnected state with respect to the packet-switched domain of the mobile communication system, a triggering message is sent from one user terminal to the other terminals of the group. The triggering message includes information about a packet-based service session to be started, and it may be a message that can be sent via the mobile communication system to a mobile terminal that is in a disconnected state with respect to the packet-switched domain. In response to the reception of the triggering message, the other terminals are brought to a state allowing reception of packets belonging to the packet-based service session. When necessary, this feature involves establishing a connection from the other terminals to the packet-switched domain.

Abstract: The present invention relates to a method, a network device (2), and a terminal device (1) for controlling the activation of packet data protocol context in a network supporting packet switched transmission of data units. A push information element HSS Push IE is added to a data base (4?) containing information to control push services. This push information element Push IE is sent to a network device (2) with a support node functionality. This push information element is evaluated. Thus, network requested context activation procedures is controlled to thereby reduce the number of unnecessary context activations.

Abstract: The invention relates to a method for supporting location determination of a mobile station, in which method location data are stored in and deleted from a memory, each location data item describing the location of the mobile station measured at a given measuring moment. Furthermore, in the method, a distance parameter and/or a target level corresponding to the distance parameter is determined at least for some of the stored location data; and deletion of the location data is at least partly based on the distance parameter and target level.

Abstract: The present invention relates to a method for controlling the sending of messages in a communication system. The method comprises providing a network entity with restriction information associated with terminating parties in the communication system. The method further comprises determining at least one terminating party for a message to be sent and controlling sending of the message based on the restriction information.

Abstract: The invention relates to a method for providing packet delivery and/or forwarding services via at least one PLMN, wherein a packet handling unit (1) receives from a content source (2, 3) content for a respective service that is to be transmitted via at least two different kinds of radio access networks (4, 5) of said at least one PLMN. In order to enable such a transmission, it is proposed that the packet handling unit (1) adapts the content data rate and/or the amount of data of the content separately for each radio access network (4, 5) via which the content is to be transmitted. The packet handling unit 1 then forwards the content to each of these radio access networks (4, 5) with the respective adapted data rate and/or the respective adapted amount of data. The invention equally relates to a corresponding packet handling unit and a corresponding communication system.
