    Abstract: 597437 Disclosed is a method in a mobility management entity (26) of a telecommunications network. The method includes negotiating use of header compression over at least a portion of a backhaul link. The backhaul link extends between a serving gateway node and a base station node of the telecommunications network. The backhaul link comprises a General Packet Radio service Tunneling Protocol (GTP) tunnel between the serving gateway node and a relay base station node (28). The General Packet Radio service Tunneling Protocol (GTP) tunnel traverses a radio interface between the relay base station node (28) and a donor base station node (70). Signalling is handled between the serving gateway node and the relay base station node (28) for negotiating by the mobility management entity (26) the use of the header compression inside the General Packet Radio service Tunneling Protocol (GTP) tunnel. The backhaul link includes a first tunnel extending between a donor base station node (70) and the serving gateway node and a second tunnel extending between a relay base station node and the donor base station node (70). The second tunnel traverses a radio interface between the relay base station node (28) and the donor base station node (70). Signalling is also handled between the donor base station node (70) and the relay base station node (28) for negotiating the use of the header compression inside the second tunnel. The backhaul link comprises a first tunnel extending between a donor base station node (70) and the serving gateway node and a second tunnel extending between a relay base station node (28) and the donor base station node (70). The second tunnel traverses a radio interface between the relay base station node (28) and the donor base station node (70). Finally, signalling is handled between the serving gateway node and the donor base station node (70) for negotiating by the mobility management entity (26) the use of the header compression inside the first tunnel.

    Abstract: 588672 Disclosed is a method implemented in an anchor base station (125) of a network, where the anchor base station (125) communicates with a self-backhauled base station (130) via a radio interface and where the network further includes another base station (155). A determination is made as to whether user equipment (UE) (110-3) is being handed off from the self-backhauled base station (130) to the other base station (155). The determination is based on receiving a message from the self-backhauled base station (130) via the radio interface (135) instructing the anchor base station (125) to stop delivering packets that are destined for the UE (110-3). Based on the determination, received packets intended for the UE (110-3) are stored and forwarded to the other base station (155) via a transport network (120) for delivery to the UE (110-3).

    Abstract: A link-level flow control method for serving ATM cell streams arriving from a number of packet sources determines a requested bandwidth share for each packet source and queues ATM cells arriving from the packet sources in a shared FIFO buffer. Based on the number of transmitted ATM cells during a pr e- defined time period, non-violating packet sources and violating packet sourc es are identified. The non-violating packet sources are those packet sources th at during the predefined time period do not require more than their requested bandwidth share, and the violating packet sources are those packet sources that during the same period require more than their requested bandwidth shar e. In order to maintain fairness among the packet sources, the non-violating packet sources are granted no more than their requested bandwidth share, wit h the remaining bandwidth not granted to the non-violating packet sources bein g granted to the violating packet sources.

    Abstract: Método y disposicion para el traspaso de un equipo de usuario de una radioestacion de base de origen a una radioestacion de base de destino en un sistema de radiocomunicaciones moviles. Una radioestacion de base de destino reserva un recurso para eltraspaso de un equipo de usuario durante un periodo de tiempo limitado. Se informa al equipo de usuario. El equipo de usuario determina un intervalo de tiempo durante el cual se han reservado los recursos, por ejemplo, recuperando la informacion detemporizacion de un comando de traspaso, y transmite un mensaje de sincronizacion a la radioestacion de base de destino durante el intervalo de tiempo determinado.

    Abstract: The present invention relates to methods and arrangements for handling UE capability information a mobile telecommunications network wherein an eNodeB (100) receives (60) information regarding the UE capability information from the UE (120) and stores (70) the information. The eNodeB (100) sends (80) the UE capability information to the EPC, i.e. the MME (130). The MME (130) receives and stores (90) the UE capability information. When the UE (120) transits from idle to active state, does an initial attach or when a part of the UE capabilities have changed, it sends (10) a message Ma to the eNodeB (100) regarding the update. The eNodeB (100) receives the message and sends (20) it to the MME (130). The MME (130) sends (30) a response associated with the previously stored UE capability information to the eNodeB (100). The eNodeB (100) decides (40) if the UE capabilities stored in the MME (130) is up-to-date based on the message sent from the UE (120) and the received response from the MME (130). If the UE (120) holds updated UE capabilities the eNodeB (100) could request (50) updated UE capability information from the UE (120).
