摘要： A method and an apparatus for performing Transmission Control Protocol (TCP) communication at a network node in a wireless communication system are provided. The method includes receiving, by the network node that connects between a Mobile Station (MS) and a data network, a TCP KeepAlive packet for maintaining a TCP connection established between a correspondent node and the MS through the data network from the correspondent node, transmitting, by the network node, when it is determined that the MS is in an idle mode upon receiving the TCP KeepAlive packet, an acknowledgement packet in response to the TCP KeepAlive packet to the correspondent node, and transmitting, by the network node, indication information indicating the reception of the TCP KeepAlive packet to the MS.

摘要： Embodiments of the invention are directed to systems, methods and computer program products for routing traffic in a packet data network (PDN). A method includes determining whether the mobile device has an active long-lived data traffic session over an original PDN connection between the mobile device and a first PDN gateway (P-GW); if the mobile device has an active long-lived data traffic session, then routing any new long-lived data traffic session over the original PDN connection; and if the mobile device does not have an active long-lived data traffic session, then routing any new long-lived data traffic session over a location-based PDN connection established based at least in part on a current location of the mobile device. In other words, the mobile device initiates and maintains all long-lived data sessions (for which service continuity is essential) to only one PDN connection.

摘要： Systems and methods to reduce control data traffic between a hub radio device (e.g., a master white space device) and spoke radio devices (e.g., slave white space devices). Reduced are the number of control messages and/or the amount of data transmitted in control data messages. The hub radio device stores data regarding the spoke radio devices that register for white space access (e.g., specific spectrum access credentials) with a spectrum management server via the hub radio device. As long as conditions regarding a spoke radio device remain relatively unchanged, the stored data for the spoke radio device may be used to maintain the white space access through periodic renewal of the corresponding channel authorization with the spectrum management server.

摘要： A system and method of transmitting packets from a wireless device is provided. According to a broad aspect, the wireless device is to transmit a packet on a communication channel during a time window based on whether or not the communication channel is expected to be torn down during the time window. If the communication channel is not expected to be torn down during the time window, then the wireless device transmits the packet late in the time window. However, if the communication channel is expected to be torn down during the time window, then the wireless device transmits the packet during the time window just prior to when the communication channel is expected to be torn down. This prevents having to re-establish the communication channel merely to transmit the packet if the communication channel is torn down.
摘要翻译：提供了一种从无线设备发送分组的系统和方法。根据广泛的方面，无线设备是在时间窗口期间基于通信信道是否期望在时间窗口内被拆除来在通信信道上发送分组。如果通信信道在时间窗口期间预计不会被拆除，则无线设备在时间窗口中迟迟发送数据包。然而，如果期望通信信道在时间窗口期间被拆除，则无线设备在通信通道预期被拆除之前的时间窗口期间发送分组。这防止了如果通信信道被拆毁，则仅需要重新建立通信信道来传送分组。

摘要： The invention relates to a method for dynamically controlling the PUSCH of a SCell in a backhaul link of a communication system utilizing a relay node with carrier aggregation, where the SCell is inband with respect to the access link between the relay node and the UEs. In order to avoid subframe blocking due to inband operation, the PUSCH of an SCell may be deactivated. The new downlink-only configuration of the SCell allows the relay node to use all resources of the SCell for scheduling resources for uplink and downlink transmissions in the access link. The PUSCH may deactivated and activated e.g. depending on the need for higher data rates in the uplink and downlink of the access link between the relay node and the UEs. The decision to deactivate/activate the PUSCH of an SCell may be taken by the DeNB or the relay node.

摘要： Even when a terminal goes out of a macro cell, data communication in the small cell can be caused to continue while the mobile management in a macro cell is continued. When a first determination unit (205) determines that a terminal exists outside the cell of a base station (200), an existence recognition packet transmission/reception unit (207) transmits a recognition packet, which is used for recognition, to the terminal via a small cell, and thereafter receives a response to the recognition packet from the terminal via the small cell. When a second determination unit (206) determines, because of the reception of the response, that the terminal exits inside the cell of the base station (200), a radio resource control unit (204) causes the connection of the control plane between the terminal and the base station (200) to continue.

摘要： Techniques for maintaining an always-on data session for an access terminal are described. Messages to keep alive the data session may be sent using non-traffic channels to avoid bringing up traffic channels just to send these messages. In one design, an access network may send a first message (e.g., a RouteUpdateRequest message) on a first non-traffic channel (e.g., a control channel) to the access terminal. The access terminal may return a second message (e.g., a RouteUpdate message) on a second non-traffic channel (e.g., an access channel) to the access network. The access network may then send a third message (e.g., for an Echo-Request) on the first non-traffic channel over a smaller area covering an approximate location of the access terminal, which may be determined based on the second message. The access terminal may return a fourth message (e.g., for an Echo-Reply) on the second non-traffic channel to the access network.
