Abstract: A search engine for finding objects that correspond to a search request, including an input module for receiving a keyword query from a user, and a search module being configured to map the keyword query to the identifiers of objects that semantically match the keyword or the plurality of keywords contained in the keyword query, and to generate a search result that contains a listing of matching object identifiers, is characterized in that the search module is further configured to generate the search result by considering network layer information about the user within the process of mapping the keyword query to identifiers of matching objects, wherein the network layer information include sophisticated information the search module receives from a dedicated entity.

Abstract: For allowing a simple and reliable differentiation of UEs behind a GW from an AF side a method for providing access of an User End device (UE) to a service provided by an Application Function (AF) within a network structure is claimed, wherein the UE is authenticated by a Gateway (GW) to which the UE is attached and which provides access to the AF via a Broadband Access Network (BB Access Network).

Abstract: A method for accessing content in networks, preferably in wide area networks, includes: determining a resource for content by a resource identifier; sending a DNS-query for resolving an IP-address for a host identifier specified as a part of the resource identifier by a client; determining a preferred hosting server hosting the content according to the resource identifier; sending a DNS-response including the IP-address of the determined hosting server to the client; accessing the content from the determined hosting server by the client by providing at least one hosting server identifier or one IP-address corresponding to the resource identifier to a sorting server; sorting the at least one hosting server identifier or IP-address by the sorting server according to client specific information or according to network guiding information provided by the client, determining a preferred hosting server according to the sorted at least one hosting server identifier or IP-address.

Abstract: A method for performing mobile CDN request routing includes receiving, from a user terminal attached or subscribed to a communication network, a content request initiated by the user terminal towards a mobile content delivery network (mCDN). The content request is processed within the mCDN by selecting a cache at which the requested content is available. Internal mCDN request routing decisions are determined based on control plane information from the network core of the communication network.

Abstract: For allowing a reliable and high performance of a network, a method for operating a network is described, wherein the network includes a server and at least one client for communication with the server, an application computation or operation will be performed by the server and the result of the application computation or operation will be displayed at the client. The method is characterized in that a network element will be provided for use by the client, wherein the network element performs at least one application computation or operation on behalf of the server. Further, a corresponding network for carrying out the above mentioned method is also disclosed.

Abstract: A method and a system for delivering media data to a user's mobile device, wherein a service control (2) is configured to receive media content related requests from the user's mobile device (1), wherein the service control (2) forwards the user's requests to a network-based media recorder (4), which records media data corresponding to the user's requests, wherein at least one caching element (3) is provided, at which recorded media data is being cached and which allows forwarding of cached media data to the user's mobile device (1), and wherein the service control (2) is further configured to receive information regarding the user's context, wherein the context information is used to control the forwarding of media data recorded by the media recorder (4) to the caching element (3).

Abstract: A method for establishing and maintaining a connection between at least one terminal and at least one communication server, preferably for using the connection in case of VolP (Voice over IP) communication, wherein the terminal and the communication server are connected over a network, wherein the establishment and the maintenance of the connection are controlled via a protocol, and wherein parameters of the connection can be adjusted by a configuration is—regarding the configuration that is feasible by an average user—characterized in that the configuration is performed in an automated way, and that configuration information is transmitted in order to configure the connection with messages of the protocol as existing according to the standard specifications.

Abstract: A method of monitoring and protecting a network against attacks from a public network, particularly from the Internet, where the network includes a firewall and an attack detection system on the protected side of the firewall, which inspects data packets passing the firewall and installs protective policies at the firewall in case of detecting data packets representing an attack. Regarding high flexibility and quick adaptability to changing attack situations, the method is characterized in that the firewall is configured by the attack detection system in such a way that the attack detection system or a system co-operating with the attack detection system is provided information about data packets representing an attack.

Abstract: A data communication method between hosts belonging to different private networks having their own private address spaces, each of the private networks Including at least one network address translator (NAT) and a proxy server accessible from a public address space. The one host obtains an outside-accessible address of the other proxy server and sends a path-coupled signaling packet using the outside-accessible address toward the other proxy server. At the NAT which the path-coupled signaling packet passes in the private network to which the one host belongs, a public address is allocated to the one host. The allocated public address is sent to the other host, allowing the one host to receive data from the other host. When receiving a public address from the other host, data communication is made possible both an the one host and the other host.
