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.

The invention is directed to an instant messaging method and communication system comprising one or more network elements, wherein a connection from one to 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.

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.

The invention proposes a method for providing context-related information, comprising the steps of analysing (S1, S2) whether a message contains a predetermined expression, and in case the predetermined expression is contained in the message, generating (S4) a predetermined information based on the predetermined expression. The invention also proposes a corresponding network system.

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 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 in order to derive a second routing information and a cellular identity of the mobile terminal, 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.

The invention proposes a method for controlling a network comprising the steps of providing presence information to a user, wherein the presence information includes information regarding the presence of at least one other user in a network, and providing session handling information, wherein the session handling information includes information about how a session, which can be initiated to the other user, will be handled. The invention also proposes a corresponding network control device.

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.
