Abstract: The invention is directed to a communication network wherein a direct tunnel may be formed between a user equipment and a gateway support node, bypassing an intermediate serving support node. If, however, the gateway node should be outside of the actual communication network to which the user equipment is connected, a two-tunnel concept is used wherein a tunnel is provided between the user equipment and the serving support node. Likewise, when receiving a request for Lawful Interception, the tunnel formed between the user equipment and the gateway node is reconfigured to be directed to the serving node for guiding all user traffic and control signaling via this serving node.

Abstract: An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in said activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from said support node to said user equipment. Said activate PDP context accept message acknowledges said activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

Abstract: A network element, such as a radio network controller, for use in a communication network (e.g. UMTS), the network element being arranged between an end station and an end element, for example an SGSN, wherein connections are established between the end station and the end element via the network element, the network element determining if the connection between the end element and the end station is to be released.

Abstract: In conventional cellular systems, the identifier of network elements (SGSN) allocating a temporary identity (TLLI) to a mobile station (MS) can be derived from the identities of the cells they serve. In the future, this assumption may no longer be valid. One paging area could be handled by several network elements, such as SGSN nodes, or one network element could serve many paging areas. When the mobile station changes its paging area, the new supporting network element may have trouble in determining the old supporting network element on the basis of the paging area identifier. It is also possible for two supporting network elements to allocate the same TLLI to two different mobile stations. Therefore the network element (SGSN, BSC, RNC) allocating a temporary identity (TLLI) to a mobile station (MS) should incorporate at least part of its own identifier (NEI) into the temporary identity (TLLI).

Abstract: In a method for mobile access of a mobile device for a system providing cellular and non-cellular mobile access, the system comprises a serving node, a packet gateway node and the mobile device. The method comprises the steps of negotiating a direct tunneling connection between the mobile device and the packet gateway node by the serving node, wherein the direct tunneling connection is only dedicated to packet switched traffic of the mobile device using the non-cellular mobile access, and establishing the direct tunneling connection between the mobile device and the packet gateway node by the mobile device.

Abstract: A method, system and network element for providing an address transition if a connection point at one end of a connection is changed from a first network node to a second network node of a cellular network is provided. An address information and at least one alternative address information are transmitted in a signaling message from the first network node to the second network node. One of the address information and the alternative address information is selected at the second network node and used for re-establishing the connection towards the other end of the connection. Thereby, the new point of connection is allowed to re-establish the connection towards the other end of the connection, even if it can only communicate using one of the two addresses. Furthermore, signaling messages, e.g. messages relating to charging, lawful interception, and/or customized applications, received from different network nodes can be correlated based on the alternative addresses.

Abstract: Routing packets belonging to different quality of service flows in a packet data network system is described. For each application initiated by a subscriber equipment with an associated quality of service flow in a multi-session connection settings of a network node hosting the application are obtained. From the obtained settings configuration information are determined and packets are routed from the network system to the subscriber equipment for each initiated application in accordance with the configuration information.

Abstract: A method, system and network element for forwards a terminal identity from a first core network node to a second core network node via a common radio access network. The common radio access network is arranged to incorporate a derived terminal identity received from the first core network node into a signaling message transmitted to the second core network node. The second core network node may then use this terminal identity to address the concerned terminal device.

Abstract: The invention proposes a system and method for providing a connection in a communication network which comprises several network elements and is adapted to route a connection via a first network element such as a radio network controller and one or more of alternatively selectable second network elements such as serving nodes. The network comprises a network element which stores a list of selectable second network elements. The list is accessed using an identifier identifying a routing or location area or a desired second network element. The list can be stored in a DNS server which returns to an inquiring network element such as a radio network controller, e.g. IP addresses of serving nodes capable of serving a routing or location area of a connection originating or terminating network element. The connection originating or terminating network element may also be adapted to send an identifier identifying a specific network element such as an SGSN to which it desires to be connected.

Abstract: A method, a system and a network node for determining services accessible via a subscription having an account and at least a first limit in a communication system. The method includes defining at least a first set of services and a second set of services to be used with the subscription, each set of services defining services accessible via the subscription, comparing the balance of the account with the first limit, using the first set of services when the balance of the account does not reach the first limit, and using the second set of services when the balance reaches the first limit.

Abstract: A method and arrangement for determining the expiry time for a period during which the re-establishment of lost radio bearers is allowable. There is determined a first expiry time (206, 207) for a period during which the re-establishment of lost radio bearers used to provide services of a first category, like real time services, is allowable. Additionally there is determined a second expiry time (208, 209) for a period during which the re-establishment of lost radio bearers used to provide services of a second category, like non-real time services, is allowable.

Abstract: An arrangement for providing IP mobility for a mobile station (MS) provides a care-of-address (COA) for routing data packets when the MS is away from home. In one embodiment, the arrangement includes support nodes, called gateway GPRS support nodes (GGSN) or serving GPRS gateway support nodes (SGSN), and a foreign agent (FA) having an IP address. In order to save IP addresses and radio resources, the FA is integrated into one of the support nodes (e.g., the SGSN), and the IP address of, or an IP address provided by the FA is also used as the MS COA.

Abstract: A method of transmitting packets of data in a communication network comprising at least first to third stations, the method comprising the steps of sending a first number of the data packets from the first station to a second station; identifying which of the first number of packets are correctly received by the second station from the first station; and sending a second number of data packets from the third station to said second station commencing with the packet identified as being required after the last correctly received packet received form the first station.

Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.
