Abstract: A synchronization method and a device in a communications network are provided. A control node obtains information about a time difference between at least one group of two adjacent network nodes in a to-be-synchronized area; determine, according to the information about the time difference between the two adjacent network nodes, a time adjustment value that needs to be used when a to-be-synchronized network node in the to-be-synchronized area is synchronized with a selected reference node; and send the determined time adjustment value to the to-be-synchronized network node, so that the to-be-synchronized network node adjusts time of the to-be-synchronized network node according to the corresponding time adjustment value. The control node is used to implement synchronization control on network nodes in the to-be-synchronized area. This solution is easy to implement, and reduces costs because there is no need to install GPS on each network node.

Abstract: A method, apparatus and system for establishing S1 signaling connections in an evolved network are disclosed. A source evolved NodeB (eNodeB) sends a handover request message to a target eNodeB to initiate a handover procedure during that a user equipment (UE) is handed over from the source eNodeB to the target eNodeB. The handover request message includes information about an original S1 signaling connection parameter. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a handover complete message to an evolved packet core (EPC). The handover complete messages carries the original S1 signaling connection parameter received from the source eNodeB and the allocated new S1 signaling connection parameter about the target eNodeB. With the present disclosure, the inability of the target eNodeB to establish an S1 signaling connection with the EPC in the related art is effectively solved.

Abstract: This application provides a method and an apparatus for configuring minimization of drive-tests MDT. The method for configuring MDT includes: A terminal device receives first MDT measurement configuration information and first indication information from a first network device. The terminal device learns, based on the first indication information, whether a type of first MDT configured by the first network device for the terminal device is signaling based MDT or management based MDT. Further, after establishing a connection to a second network device, the terminal device sends second indication information to the second network device, and reports the type of the first MDT that has been configured for the terminal device. The management based MDT overwrites signaling based MDT previously configured by the first network device for the terminal device can be avoided, thereby increasing a possibility that the management based MDT does not overwrite the configured signaling based MDT.
