Upper layer applications discover, establish and manage the QoS connectivity through a SIP (session initiation protocol) that serves as a unified interface. In one implementation, this is IP Multimedia Subsystem-centric, further supporting applications that utilize SIP for session control. This capability extends to the data card universe allowing UMTS data card vendors to establish concurrent QoS-based sessions using multiple primary PDP (packet data protocol) contexts based on a set of SIP triggers, further allowing applications running on a computing system to transparently utilize the established pipes based on the individual QoS requirements.

Similarly, a QoS information element (IE) is defined that supports upgradeable QoS requirements.

The present invention relates to a method and system for providing access to a cellular network (8), wherein a terminal device (1) is connected to an access device (2) according to access specifications of a broadband access network (12) which is not specifically designed to be used as a part of cellular network (8). The terminal device (1) indicates to the access device (2) that it wishes to be connected to the cellular network (8), and a session or call and a radio bearer is setup between the terminal device (1) and the cellular network (8). To achieve this, a service node (5) provided in the cellular network (8) requests a suitable access bearer from the access network (12) and the access device (2) sets up a corresponding access channel towards the terminal device (1). The terminal device (1) then associates the access channel to the correct radio bearer by using a corresponding identification. Thereby, service functions of the cellular network, e.g. UMTS services, can be distributed via any access network and existing broadband or high-speed access networks can be implemented in new cellular network structures. A huge capacity enhancement can thus be offered to the network operators of the cellular network without any standardization effort or license fee and at very small investment and maintenance costs.

A method of authorizing an Internet Protocol (IP) enabled mobile host 1 to access the Internet 2 via an wireless LAN, GSM, UMTS access network 3 comprises initially sending an IP access request from the mobile host 1 to an IP router 5 within the access network 3. In response to receipt of said access request at the IP router 5, an IP address routing prefix is sent from the IP router 5 to the mobile host 1. Electronic cash is then forwarded from the mobile host 1 to a control point 6 within the access network 3. The control point 6 confirms the authenticity and / or sufficiency of the electronic cash and, providing that confirmation is made, sends an authorization message to the IP router 5. The IP router 5 blocks the transmission of IP packets between the mobile host 1 and the Internet 2 prior to receipt of the authorization message and permits the passage of IP packets only after an authorization message has been received.

A multicast service of a 3GPP Universal Mobile Telecommunications System (UMTS) is disclosed. By allowing an RNC to manage multicast group member information by multicast services on multicast areas, when a user terminal being currently provided with an MBMS service moves, the RNC sends information on the movement of the terminal to a core network. Since the RNC notifies the core network of the terminal's movement selectively on the basis of the multicast group member information by multicast services on the multicast area, the network resource can be effectively used, and especially, unnecessary transmission of terminal's movement information from the RNC to the multicast group managing entity of the core network can be prevented.

In this manner, for user equipment, e.g., a Universal Mobile Telecommunications System mobile station, a decision algorithm in a Universal Mobile Telecommunications System Terrestrial Radio Access Network may direct at least a part of the traffic load on a shared channel from a source cell to a target cell by moving a cell border without affecting a traffic load on a dedicated channel.
