Abstract: A node in a first network domain and a method performed thereby for transmitting a data packet to a VPN client in a second network domain, the node and the VPN client being part of a VPN, wherein the first and second network domain are connected by means of a third network domain are provided. The method comprises receiving, from an application server, a first packet comprising a first IP header and a payload; and determining a DCSP. The method further comprises adding a second header comprising the determined DCSP and an IP address of a VPN client resulting in a second packet and encrypting the second packet. Further the method comprises adding a third header to the encrypted second packet resulting in a third packet, the third header comprising a destination address of a node in the second network domain, and transmitting the third packet in an IP tunnel terminating at the node in the second network domain.

Abstract: A telecommunications network (10) comprises a group call service server (18) which facilitates a group call over a radio interface (32) between different user equipment units (30) in a defined group within the telecommunications network. The group call service server (18) receives a floor request from a requesting user equipment unit (32j) included in the group, and handles the floor request based on a media type associated with the floor request. In conjunction with such handling, in one aspect of its operation the group call service server prioritizes the floor request from the user equipment unit based on the media type (e.g., based on delay sensitivity of the media type associated with the floor request). In one example implementation, the group call service server comprises a queue (42) and a floor request handler (40).

Abstract: In a telecommunications network, an ATM Adaptation Layer 2 (AAL2) signaling protocol is employed independent of the signaling bearer service being used in transport signaling messages to and from various network entities, such as mobile switching centers, radio network controllers and cell base stations in, for example, a mobile telecommunications network. This is achieved by dividing the functionality of the AAL2 signaling protocol into a number of functional sublayers including an AAL2 Signaling Common Part (CAP), a Bearer Coordination Part (BCP) and a Bearer Adaptor Part (BAP), wherein the BAP adjusts incoming and outgoing messages so that they are compatible with the AAL2 signaling protocol or the underlying signaling bearer service respectively.

Abstract: A system and method for optimizing network resources in an ATM network wherein existing virtual channel connections (“VCCs”) are checked for an available channel identifier (“CID”) and network bandwidth in response to a connection request. If a CID and required bandwidth is not available, then a new VCC is established and the requested AAL2 connection is setup. Rather than establishing a new direct VCC, available resources on an indirect VCC may be used.

Abstract: A network element included in a telecommunication system contains several nodes (1226, 1232, 1234, 1236, 1238) which are included in a system internal to this network element and provides internal network element functions in an internal bearer service network, and internal resources in the form of hardware and software which are used for performing the internal network element functions.The network element can offer an operations system a "white box" view, implying that internal resources are available to this operations system, enabling it to use managed objects representing the internal resources in order to manage the resources according to a second management information model in connection with using them for performing internal network element functions.

Abstract: A network element in a telecommunication network providing a number of different types of services, supports several telecommunication network applications (1304, 1306). It furthermore contains system resources and management information software. This software includes application specific management information and management information for system resources common to the applications, and is available to an operations system for managing the system resources when they are to be used. All of said management information is organized, from the point of view of naming, in several application specific management information bases each in the form of a respective hierarchical tree structure (1310, 1312).
