  • Patent number: 9281869
    Abstract: A network repeater is configured to repeat data packets in a broadcast mode without generating a significant broadcast storm. The network repeater is configured to detect a characteristic of a received data packet. The data packet characteristic is compared with valid copies of packet characteristics previously stored in a packet registry. During a delay period, if a valid copy of the detected characteristic is found in the packet registry, then it is assumed that the packet is being received for the second time and the data packet is not repeated in the broadcast mode. If a valid copy of the detected characteristic of the data packet is not found in the packet registry, then the characteristic is stored in the packet registry and the data packet is repeated in a broadcast mode.

  • Patent number: 9277456
    Abstract: The technology described herein relates to a method in a gateway device and a gateway device for handling a context of a UE moving from a source HeNB (220) to a target HeNB. The gateway device is configured to receive a path switch request message from the source HeNB including a first pair of IDs and the gateway device is configured to transmit a second path switch request message to an MME including a second pair of IDs associated to the first pair of IDs. When the gateway device receives a UE context release request message from the source HeNB, the gateway device determines whether IDs in this message are associated to the same second pair of IDs. If this is the case, the gateway device maintains the UE context otherwise the gateway device releases or de-allocates the UE context.

  • Patent number: 9247453
    Abstract: Various methods and apparatus are directed to collision detection and/or avoidance regarding peer to peer connection identifiers. A wireless communications device broadcasts a signal indicating its acquired connection identifier in one of two alternative blocks. A base station monitors peer to peer signaling in its coverage area and tracks the usage of peer to peer connection identifiers by pairs of devices. The base station detects when multiple pairs of devices are using the same peer to peer connection identifier. The base station provides assistance to the peer to peer network to avoid a collision or facilitate rapid collision detection by the peer to peer devices. In one approach the base station sends an instruction for a connection to switch its connection identifier. In another approach the base station sends a connection a message to bias its selection as to which of the two alternative blocks to use for transmission.
