    Abstract: Disclosed are a communication switching and establishing method and device. A switching procedure comprises: an access network device determining to switch from a D2N link to a D2D link; sending a switching command to a first terminal and a second terminal; receiving a switching complete response; and saving bearer information of a bearer, which needs to be switched to the D2D link, in the D2N link, or requesting to send a bearer keep request to a core network node. A communication establishing procedure comprises: after the access network device determines that communication needs to be established with the D2D link, determining whether a core network side link needs to be established for communication between the first terminal and the second terminal; if yes, sending a service request to a core network device, so that the core network device establishes a core network side link for the service request; and sending configuration information of the D2D link and establishment instruction information of the D2D link to the first terminal and/or the second terminal. The present application enables a first terminal and a second terminal to perform D2D communication, thereby enhancing network transmission efficiency.

    Abstract: The present disclosure provides a retransmission activating/deactivating method, a base station, a user equipment and a device. The method includes: determining a correspondence relationship between a bearer which is allowed for retransmission under the first base station and a bit of a preset field of media access control (MAC) control element (CE) of the first base station for activating/deactivating retransmission; where the preset field is used to indicate activation/deactivation retransmission of the bearer which is allowed for retransmission; and, when determining to activate/deactivate retransmission of the bearer which is allowed for retransmission under the first base station, populating, by the first base station, the bit, which is in the preset field of the MAC CE for activating/deactivating retransmission and corresponding to the bearer, thereby generating the MAC CE for activating/deactivating retransmission, and transmitting to the UE the generated MAC CE for activating/deactivating retransmission.

    Abstract: Disclosed in the present disclosure are a processing method and device for a cache synchronous exception, for solving the problem that no solution for a compression check failure is available in the prior art. According to embodiments of the present disclosure, when caches are out of synchronization, a caching failure notification message is sent to a transmitting device; a reset processing is carried out on a compressed cache area, and a reset instruction is sent; and then subsequent data packet transmission is carried out by using reset cache areas. In the present disclosure, after it is determined that the caches are out of synchronization, the caching failure notification message is sent; the transmitting device performs a reset processing on the compressed cache area, and notifies a receiving device to carry out a reset processing on a decompressed cache area.

    Abstract: Disclosed are a data transmission method, device, and system, which are used for resolving the problem of large overhead if an existing manner of sending a public message periodically is used in an ultra-dense network. The method comprises: user equipment sends an uplink request message, the uplink request message being used for requesting for obtaining public information of a first access node in an area in which the user equipment is located; and the user equipment receives the public information sent by the first access node. Because an access node in an area in which user equipment is located does not need to broadcast and send public information periodically, the access node can send, based on an uplink request of the user equipment, the public information, thereby improving the resource utilization and reducing the energy consumption.

    Abstract: An information exchange method and device for addressing a coordination problem between different access points (APs) caused by low exchange efficiency between the APs. The information exchange method provided in an embodiment of the present invention comprises: determining, by a transmitting AP, an air interface broadcast resource for transmitting information to a receiving AP; and transmitting, by the transmitting AP and based on the determined air interface broadcast resource, the information to the receiving AP in a broadcast form. Adopting the embodiment of the present invention not only allows an air interface transmission to be performed between the APs, but also allows communication between more than two APs. One AP can transmit information thereof, in the broadcast form, to all neighboring APs having a needing to exchange information therewith, thereby improving coordination efficiency between the APs.
