摘要:
A packet switched (PS) core network (CN) supporting several quality of services levels, comprising at least a serving node (SGSN), a gateway node (GGSN), a home location register (HLR), a short message service gateway and interworking unit (SMS-GMSC, SMS-IWMSC), charging gateway functionality (CGF), and a public data network (PDN) comprising an application server (AS). The core network is adapted for carrying out a packet data protocol (PDP) context activation in which a PDP address is assigned to a mobile station and in which a given quality of service is assigned through the network in a communication session between the mobile station and the application processor in question, whereby the application server (AS) initiates a context activation in which the QoS is seeked altered for the mobile station.

A pool of functional server nodes in a packet data network, and method of transferring a given mobile terminal from a current functional server node to a target functional server node in the pool. An interface enables each functional server node to control any, or a number of, radio network control nodes. When a transfer is desired, the pool selects the target functional server node and initiates a transfer of control responsibility for the given mobile terminal's connections from the current functional server node to the selected target functional server node. The control responsibility is then transferred to the selected target functional server node without interrupting service to the given mobile terminal.

A packet data core network node and methods supporting packet data communication are disclosed. In one embodiment, a packet date core network node in a first core network comprises a first communication mechanism for control plane handling and mobility management, a second communication mechanism for user plane management and a mechanism for communication with a dual mode mobile terminal over a first radio network. The packet data core network node comprises or communicates with a mapping function for mapping between first radio bearers used in the first core and radio networks and second radio bearers of a type different from the type of the first radio bearers and used in a second core radio network at handover of a dual mode mobile terminal from the first core network to the second core network or vice versa. Another embodiment is a dual mode mobile terminal including such mapping function.

The invention relates to a method and devices for the automatic configuration of a GPRS terminal. Therefore data relating to a terminal type and a terminal identification are stored in a device configuration register. The configuring is started by a serving GPRS support node that receives an attachment message from a terminal in combination with a subscriber identification that are not known to the serving GPRS support node.

A packet radio data network and methods have been disclosed, the network comprising at least a gateway node (GGSN), at least one serving node (SGSN) connected to the gateway node, a plurality of radio access nodes (RAN) connected to the serving node (SGSN), the packet radio network transporting packet data from an external packet data network, comprising an Internet Service Provider (ISP), to mobile stations (MS) wirelessly attached to radio access nodes (RAN). The gateway node, subsequent to a PDP multipoint context activation procedure, establishes at least a first multicast tunnel (GTPT1 GTPT4, GTPT10 GTP35) between the gateway node and at least one serving node, the multicast tunnel carrying IP streams pertaining to at least two mobile stations belonging to a common multicast group.

The present invention relates to an arrangement, for allowing compensation of lost, discarded or unsent traffic on the downlink in a communication system supporting communication of packet data and classification of mobile traffic allowing application of different charging schemes for different types of traffic. It comprises a packet data node (PDN, G-PDN; GGSN; SGSN, CGSN) handling classification of traffic into different types, e.g. service class, and for applying an appropriate charging scheme depending on type. Said node provides (labels) and sends information relating to at least type, e.g. service class, to subsequent nodes (PDN, SGSN; RNC; BSC) on the downlink to a mobile station and a subsequent node (PDN; SGSN; RNC; BSC) detecting a packet loss, notes said loss and enables use of the information of the said loss together with at least type information to enable for correction of charging due to traffic loss.

The present invention relates to a communication system supporting data communication and comprising at least a first core network with a plurality of circuit switched (CS) core network functional server nodes and a second core network with a number of packet switched (PS) core network functional sever nodes for packet switched communication. The CS core nodes are arranged in a pool and an interface (Gs) between CS core nodes and PS core nodes is used for providing information to CS core nodes from PS core nodes relating to mobility related events provided from an MS to a PS core node. When a mobile station moves from a first CS core node to a second CS core node the PS core node to which the MS is connected is provided with information relating to the change from said first to said second CS core node.

A packet radio data network has been disclosed, wherein the network comprise at least a gateway node (GGSN), at least one serving node (SGSN) coupled to the gateway node, a plurality of radio access nodes (RAN) coupled to the serving node (SGSN), the packet radio network transporting packet data from an external packet data network, comprising an Internet Service Provider (ISP), to mobile stations (MS) wirelessly attached to radio access nodes (RAN). A given mobile station (MS) issues a membership report message indicating that the mobile station wishes to receive content of a specific multicast group (1), whereupon the gateway node (GGSN) issues a multicast context activation message to the serving node (SGSN) (2). The serving node (SGSN) informs the radio access network (RAN) that the mobile station is joining the respective multicast group (3) and sends a multicast activation response to the gateway node (GGSN) (4).
