Abstract: Provided are methods and devices for transmitting or receiving Device-to-Device (D2D) broadcast information, and a transmission system. The method for transmitting the D2D broadcast information includes that: classification information of service information to be transmitted is acquired; control information corresponding to the classification information is acquired, wherein the control information is used for indicating resource scheduling information used during transmission and/or retransmission of the service information; and the service information and the control information are transmitted in a broadcast manner according to a preset rule.

Abstract: The disclosure provides a positioning service method and system, and a terminal. In the above method, a positioned terminal receives a movement track model established by a positioning service platform; the positioned terminal judges whether or not positioning data that are collected satisfy the movement track model; and when the positioning data satisfy the movement track model, it is determined that there is no need to report the positioning data, and when the positioning data do not satisfy the movement track model, the positioning data are reported to the positioning service platform. The technical solution provided by the disclosure can reduce the frequency for the positioned terminal to report the positioning data and also save network data traffic for the user.

Abstract: A method and system for measurement reporting in a Coordinated Multipoint transmission/reception (CoMP) system are disclosed in the present invention. The method includes: according to a CoMP measurement configuration message sent by a serving cell, when a measurement event report triggering criterion is satisfied, a terminal reporting a measurement report to the serving cell; wherein, the measurement event report triggering criterion includes: a movement speed measurement value of the serving cell being lower than a preset first measurement threshold, and a ratio of a Reference Signal Received Power (RSRP) measurement value of the serving cell to an RSRP measurement value of a measuring cell being lower than a preset second measurement threshold.

Abstract: A display method and device are provided, wherein, the display method includes: obtaining a preset display mode parameter when an application refreshes a screen; placing a bitmap of a specified application interface into a set area according to the display mode parameter; and mixing a background bitmap with the bitmap in the set area and then displaying. The display method and device can achieve the objective of power saving of a mobile terminal by means of adjusting a position of a display area and a display scale for displaying the application interface on the display screen.

Abstract: A method and a system for intra-BS carrier handover are provided. The method comprises: a mobile station scanning predetermined carriers within the base station based on predetermined rules; obtaining a scanning report comprising channel quality information of part of or all of the predetermined carriers; and sending the scanning report to the base station; the base station obtaining the channel quality information in the scanning report; selecting a target carrier from the predetermined carriers; and informing the mobile station of the selected target carrier via a message; and the mobile station handing over to the target carrier in a predetermined manner in response to the message. By using the method, seamless handover of intra-BS carriers can be performed in a multi-carrier system for ensuring the service continuity of the mobile station to eliminate carrier handover time delay.

Abstract: A mobile terminal and a file browsing method implemented by the mobile terminal are disclosed, including: a scanning module scans the files in the mobile terminal and acquires related information of each file in the mobile terminal; an indexing module creates a global index list according to the related information of the files; and a browsing module classifies and displays the files according to the file types in the global index list while searching a target file. According to the technical solution, the target file can be quickly and conveniently found from the mobile terminal.

Abstract: The present invention discloses a method for retransmitting hybrid automatic based on persistent scheduling. The method includes: a base station sending retransmission attribute information of a persistent scheduling service to a terminal by a control signaling. An HARQ mechanism under a persistent scheduling mode is perfected by defining a retransmission region of the persistent scheduling service, and retransmission data packets are centralized to be transmitted in the retransmission region at a synchronization time, which, compared with the prior art, saves the overhead of resource indication information indicating each retransmission packet.
