Abstract: The invention is a system and method of controlling an access of a subscriber to a network. The method includes sending an identification of the subscriber and a level of access to be provided to the subscriber from a visited network of a plurality of networks (12, 14, 16) connected to a home network (10); in response to the identification of the subscriber and a level of access to be provided to the subscriber, storing a subscriber profile of the authorized of access to be provided to the subscriber; and controlling access of the subscriber to any network dependent upon a comparison of access to be provided to the subscriber and the stored subscriber profile.

Abstract: According to one aspect, a communication network system comprising at least one first network and at least one second network providing application services over the first network is described. The system comprises first network means (GGSN) for receiving a message associated with an IP address allocated by the first network from the second network, for detecting that there is no active communication channel for this IP address which is allocated to a user equipment, and for sending an indication that the user equipment is not reachable through this IP address to the second network. The system further comprises second network means (P-CSCF/PCF) for receiving this indication.

Abstract: A method and an arrangement are disclosed for a mobile station of a cellular radio system to exchange capability information with the fixed parts of the cellular radio system. The mobile station receives capability information from the fixed parts of the cellular radio system and compares the received capability information to capability information describing the capability of the mobile station. The mobile station transmits to the fixed parts of the cellular radio system a comparison result that indicates whether matches occurred between the received capability information and said piece of capability information describing the capability of the mobile station.

Abstract: A method in a communication system, the system comprising a first entity maintaining registration information from a plurality of users and a second entity maintaining information associated with said plurality of users, wherein said second entity information is dependent on the registration information. The method comprises sending a subscribe message for an event from the second entity to the first entity, wherein the event is a change in the registration information of at least one of the plurality of users at the first entity; receiving at the first entity a register message from at least one user, said message changing the registration information of said at least one user; sending a notification from the first entity to the second entity in response to the register message, wherein the notification includes information associated with said at least one user.

Abstract: A wireless communication network is disclosed having a circuit switched network architecture and a packet switched network architecture, at least part of the packet switched network architecture supporting IP multimedia functionality, wherein the support of IP multimedia functionality is identified in a pre-registration communication between a user and the network.

Abstract: The invention relates to a method for the transmission of multimedia messages in a communication system from a transmitting terminal (MS1) to a receiving terminal (RH, MS2). The communication system comprises at least a first communication network (NW1), a second communication network (NW2) and a multimedia message switching centre (MMSC). In the first communication network (NW1), at least a first address type is used as the terminal address, and in the second communication network (NW2), at least a second address type is used as the terminal address. In the method, the address of the receiving terminal (RH, MS2) is annexed to said multimedia message.

Abstract: A method is provided for transmitting information related to the use of the Wireless Application Protocol between a first device and a second device coupled to a packet-switched data transmission network. A first protocol stack (201, 202, 203, 204, 205, 206, 207) is defined for the first device and a second protocol stack (251, 252, 253, 254, 255, 256; 511, 512, 513, 514, 515, 516) is defined for the second device. The protocol stacks consist of layers and serve the arranging of the mutual exchange of information between the first device and the second device. An octet stream protocol layer (206, 255) is defined for the transmission of unstructured octet streams as a certain layer in the first protocol stack and a certain layer in the second protocol stack. A Wireless Datagram Protocol layer (207, 256) is also defined as a certain layer above the octet stream protocol layer (206, 255) in the first and second protocol stacks.
