    摘要： A method for performing relay node configuration and re-configuration in relay enhanced networks, in particular in a 3GPP LTE-Advanced architecture, wherein the network includes a plurality of eNBs that function as donor eNBs providing wireless access to associated relay nodes, wherein the relay nodes function as eNBs from a UE perspective, is characterized in that the network is divided into clusters such that each cluster includes exactly one donor eNB and that each relay node is associated to at least one donor eNB any point in time, wherein the load of donor eNBs and the handover rates among relay nodes as well as between donor eNBs and relay nodes are monitored and/or estimated, wherein the association of relay nodes to donor eNBs is performed on the basis of the results of the monitoring and/or estimation. Furthermore, an apparatus for performing centralized relay node configuration in relay enhanced networks is disclosed.

    摘要： For allowing a particularly economic operation of a network with a high degree of energy conservation a method for operating a wireless radio network, especially a radio access network, is claimed, wherein the wireless radio network includes a core network, a number of base stations and at least one mobile host for wireless communication via at least one base station, wherein the method is characterized in that an association of powered on and powered off base stations within definable base station partitions will be arranged in a coordinated manner, thereby maintaining a minimum number or the smallest possible number of powered on base stations being necessary for accommodating a current traffic demand. Further, a network is claimed, preferably for carrying out the above mentioned method.

    摘要： A method for handling failure of a MME (Mobility Management Entity) in a LTE/ EPC (Long Term Evolution/Evolved Packet Core) network or an EPS (Evolved Packet System), wherein multiple UEs (User Equipment) are attached to a first MME, wherein said first MME stores first context information representing the UEs attached to said first MME, wherein said UEs are connected to one of multiple eNBs (evolved NodeB), wherein said eNB may communicate with said first MME and with at least one neighboring MME, and wherein said UEs may communicate with said first MME and with said at least one neighboring MME via said eNB, is characterized by the steps of detecting failure of said first MME, gathering information related to UEs attached to said first MME, wherein the step of gathering information is triggered by the detection of said failure, restoring at least parts of said first context information at one or several of said neighboring MME using the gathered information, and re-establishing network internal logical connections with said one or several of said neighboring MME using the restored first context information.

    摘要： A method for enabling multi-channel signaling in a communication network, in particular in a vehicular ad hoc network, wherein said communication network comprises a multitude of communication nodes, wherein the communication among said communication nodes is performed by way of sending and receiving messages on communication channels, wherein said communication channels include a control channel and at least one service channel, is characterized in that communication nodes embed information related to communication channel usage in messages that are sent on one of said communication channels, in particular said control channel, wherein said information indicates to others of said communication nodes a communication channel, in particular a service channel, that is intended to be employed for a specific service and/or application by the communication node having sent the respective message, and wherein communication nodes that receive a message including information related to communication channel usage forward said information by embedding said information in any of their own messages to be sent on a communication channel, in particular on said control channel.

    摘要： A method for supporting admission control and/or path selection in a communication network, the network including a plurality of wireless communication links, possibly of different link technologies, established between a plurality of network nodes, includes the steps of partitioning the communication links of the network into groups of communication links—link groups—, assigning each link group an associated link group controller that is configured to observe and/or measure the performance and/or quality of the link group, based on the observations and/or measurements, computing estimates of metrics for the capacity of the respective link group and the costs for using each of the communication links of the respective link group, and transmitting the estimates to at least one resource management entity being configured to take admission control and/or path selection decisions on the basis of the estimates. A communication network with admission control and/or path selection supporting functionality is described.
