| 20100003980 | AUTOMATIC CONFIGURATION OF INTER-DOMAIN ACCESS TECHNOLOGY NEIGHBOR RELATIONS - The disclosure relates to automatically configuring a map of inter-access technology neighbor relations. In this neighbor relations map configured by an ANDSF, relationships between neighboring cells of differing access networks of the same or different access technologies are maintained including extra-domain and non-domain neighbor relationships. A domain refers to a domain of one or more access technologies in which ANDSF is not required for intra-domain access selection and discovery. ANDSF configures the map based on neighbor relations data reports from wireless terminals, which record the neighbor relations data as they perform extra-domain or non-domain handovers or reselections or as they scan their surroundings. ANDSF provides steering instructions to configure the neighbor relations data recording and reporting behaviors of the wireless terminals. ANDSF provides access network discovery and selection information, which indicates availability of non-domain accesses, and in some cases domain accesses, to wireless terminals based on their locations. | 01-07-2010 |

| 20100097986 | Loop-Detection in Moving Networks - A method of generating network identifiers for use by mobile routers of a moving network is provided which enables fast and efficient routing loop avoidance and detection. The method comprises receiving at a mobile router of a sub-network chain, a beacon from a preceding mobile router in the chain, the beacon containing a network identifier of the preceding mobile router, generating a new network identifier by applying a pre-defined function to the received network identifier, and including the new network identifier in beacons broadcast by the receiving mobile router. When preparing for a handover, a mobile router compares the network identifier contained in a received beacon with values generated by applying said function against its own network identifier. This allows the mobile router to identify beacons originating from mobile routers that are downstream in the same chain. | 04-22-2010 |
| 20100185849 | METHOD AND ARRANGEMENT FOR CERTIFICATE HANDLING - The present invention relates to a method and an arrangement for authentication and authorization in an access network. In an initial phase of the method according to the invention the user equipment and the security gateway exchange information on available certificate(s). If the user equipment and the security gateway lack matching certificates, the attempted authentication of the security gateway can not take place according to existing protocols and arrangements. According to the invention, if a certificate mismatch is identified, a certificate server is engaged. The certificate server, which is a separate entity from the security gateway, assists in at least part of the authentication procedure. Once the authentication is confirmed a secure tunnel can be established between the user equipment and the security gateway and payload traffic can be transferred. | 07-22-2010 |
| 20100214955 | Methods and Arrangements in a Mobile Telecommunications Network - 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. | 08-26-2010 |
| 20100226283 | METHOD AND APPARATUS FOR USE IN A COMMUNICATIONS NETWORK - A method and apparatus for use in a communications network in which a Mobile Node accesses the communications network via a proxy node. The proxy node is arranged to handle mobility signalling on behalf of the Mobile Node. At a mobility anchor function, such as a Local Mobility Anchor, a first Care-of-Address associated with the Mobile Node is registered. When the mobility anchor function receives a registration request to register a second Care-of-Address associated with the Mobile Node, it sends a request message to the proxy node acting on behalf of the Mobile Node. The request message instructs the proxy node to check whether the Mobile Node is reachable using the first Care-of-Address. | 09-09-2010 |
| 20100238811 | METHOD AND ARRANGEMENT FOR ASSURING PREFIX CONSISTENCY AMONG MULTIPLE MOBILE ROUTERS - The present invention relates to a method and an arrangement in communication systems utilising network mobility (NEMO). In moving networks comprising a plurality of mobile routers, MRs, it needs to be assured that two or more MRs sharing the same prefix, belong to the same moving network. The method according to the invention utilises a local connectivity test to determine if a MR should be allowed a certain prefix. Unique shared secrets are agreed between the MRs and the home agent, HA. The MRs derive, based on their respective shared secrets, MR specific information, which are distributed among MRs in the moving network. A MR requesting a prefix from the HA, forwards the MR specific information to the HA. By comparing data generated using its stored shared secrets with data from the MR specific information, the HA can determine whether the MR requesting a certain prefix belongs to the same moving network as MRs already using that prefix. | 09-23-2010 |
