The present invention relates to methods and arrangements for providing macro diversity, also referred to as diversity handover, DHO, related instructions to a node, e.g. a Node B, that is a part of a DHO connection in a mobile telecommunication network wherein the macro diversity functionality is distributed to a Radio Network Controller, RNC, and its connected Node Bs in said network. The method comprises the steps of: including in a signaling message one or more transport layer addresses and one or more transport bearer reference parameters in order to direct one or more data flows of the DHO connection, and sending said signaling message to said node.

Systems and methods according to these exemplary embodiments provide for improving communications systems which use home gateways or the like. This can be obtained by avoiding potentially frequent inter-MME (intra-MME pool) context transfers. This can then reduce unnecessary or redundant signalling.

The invention relates to a method and system for network access selection comprising an Access Selection Server (ASS) (113) being arranged in a communication network comprising at least one User Equipment (UE) (109) and communication nodes. The ASS (113) collects (127) access selection information used in the network for the selection of network access for the UE (109) in a multi-access environment to a Packet Data Network Gateway (PDN GW). The network access enables a traffic bearer (116) between the UE (109) and the PDN GW for the traffic flow between an application (AP) (115) in the UE (109) via the PDN GW to a first node. The method and system is particularly characterized in that an Access Selection Client (ASC) (118) arranged in the UE (109) performs activation of new network accesses and/or selection, modification or deactivation of existing network accesses on the basis of the access selection information in order to enable the traffic flow (116). The selection/activation/modification/deactivation of the network access is triggered by a socket request sent from the application (AP) to the ASC (118) for the purpose of establishing means for end-to-end communication the traffic bearer (116).

The basic concept of the present invention is to utilize the terminal as an auxiliary information collector in networks where the regular network-based information collection is not possible and/or for providing information that complements the information that the network-based Access Awareness Entity collects by itself. The terminal collects information related to the access network directly, through retrieval of explicitly available information, and indirectly, through measurements and statistics. The collected information is delivered to the network-based Access Awareness Entity.

An arrangement and method in a Public Land Mobile Network (PLMN) for selecting a gateway to connect a User Equipment (UE) to a home PLMN when the UE is located in an access network connected to a visited PLMN. The arrangement receives a first Fully Qualified Domain Name (FQDN), which includes an identity of the UE user. Based on the identity of the user and knowledge of the visited PLMN, the arrangement selects whether the UE should establish a connection only to a gateway in the home PLMN, only to a gateway in the visited PLMN, or both. The arrangement transmits to the UE, an appropriate address for the home PLMN gateway, the visited PLMN gateway, or both depending on the selection.

LAN emulation in a moving network environment is disclosed. An emulated LAN encompassing a number of moving networks is formed by means of a set of layer 2 tunnels that interconnect a home agent with mobile routers in the moving networks. The home agent and the mobile routers are arranged to perform layer 2 forwarding over the layer 2 tunnels in order to form the emulated LAN. The layer 2 tunnels can be established in a number of alternative ways. The moving networks that are part of the emulated LAN may move, i.e. change their points of attachment to the network infrastructure, in a dynamic fashion without disrupting the function of the emulated LAN.

The present invention relates to prefix management in a moving network comprising a first mobile router which is assigned a first prefix for use when passing traffic to and from a home agent with which the first mobile router is associated, and a second mobile router. The present invention relates to methods and arrangements in the first mobile router, the second mobile router and the home agent for delegating the right to use said first prefix to said second mobile router in a secure manner by means of first and second authentication information that may be compared to verify that the second mobile router has the right to use the first prefix.

The present invention relates to moving networks in communication systems. An object of the invention is to provide moving network nodes (205, 206) in a moving network (201) with the ability to simultaneously access several external access networks (211, 212, 213) accessible by different mobile routers (204, 207) such that a data packet directed to an address external to the moving network can be sent from a moving network node via any of the mobile routers (204, 207) and via a tunnel setup in any of the simultaneously accessible external accesses to a home agent (216) in a home network (215) of the mobile router. This is achieved by synchronizing between the mobile routers data regarding the external accesses of each mobile router, and, when a data packet is received at a first mobile router (204), the first mobile router selects external access based on the synchronized external access information, information in the data packet and optionally also based on access selection policies. If a selected access belongs to e.g. a second mobile router (207), the packet is forwarded from the first mobile router to the second mobile router before it is sent to the home agent (215) via the tunnel setup through the selected access (211).

The present invention relates to a method, a protocol and a control unit for managing devices in a Personal Area Network (PAN) such that a user of the PAN can use one of his devices and take advantage of services residing in any of the other devices in the PAN. The devices in the PAN are defined as either PAN controller devices or PAN auxiliary devices depending on if the devices have user interfaces suitable for controlling a PAN. When the PAN is managed according to the invention, the PAN controller devices and the PAN auxiliary devices communicate with each other via short-range communication means to exchange each other's PAN related information such that PAN related information is synchronized in the network. At least the PAN controller devices store received updated PAN related information from the other PAN participants such that the user can see an updated picture of the PAN on the PAN user interfaces. Any of the PAN controller devices can then be used to control the other PAN participants via commands and messages of the invention.
摘要:
A basic feature of the invention is to rely on an AAA infrastructure to “bootstrap” the HMIPv6 service for a mobile node (130) that “roams” in a visited network or the home network. In accordance with a preferred embodiment of the invention, bootstrapping the HMIPv6 service involves authenticating and authorizing the mobile node (130) for HMIPv6 service based on an AAA infrastructure. In an important scenario, the mobile node is roaming in a visited network, and the AAA infrastructure (110, 120, 122) links the visited network with the home network of the mobile node. The invention also supports the possibility of having the MAP (125) located in the home network or other network than the visited network. The reliance on the AAA infrastructure preferably involves transferring HMIPv6-related information required for authenticating and authorizing the mobile node for HMIPv6 service over the AAA infrastructure.
