Embodiments of the present invention provide a method and a device for reporting cell information and adjusting a cell mobility parameter. The method for reporting cell information includes a connection failure occurring on a terminal and re-establishing a radio resource control RRC connection with a cell by the terminal. A cell identity of a neighboring cell of a source cell and event information of the neighboring cell that is recorded by the terminal before the connection failure occurs is sent by the terminal to a base station that controls a cell where the RRC connection is re-established. Technical solutions provided in embodiments of the present invention may help improve the accuracy of mobility parameter adjustment on a network side and further improve the terminal handover efficiency.

The invention discloses a trans-pilot-frequency cell mobility scheme realizing no downstream data loss of group calling terminal. The scheme includes that an access network configures a measurement threshold established for triggering RRC connection for the group calling terminal and the terminal triggers an RRC connection establishing process after meeting the measurement threshold; after the group calling terminal implements the establishing of the RRC connection, the access network configures a pilot frequency measurement GAP according to a group mark of a group calling UE and the group calling terminal uses the pilot frequency measurement GAP for pilot frequency measurement; the access network triggers the ground calling terminal to switch to a target pilot frequency cell if pilot frequency switching conditions are met. According to the invention, through the arrangement of the measurement threshold and the triggering of the establishment of the RRC connection after that the terminal meets the measurement threshold is judged, pilot frequency measurement of the group calling terminal is realized. Thus, the group calling terminal is triggered to switch to the target pilot frequency cell after the access network meets the pilot frequency switching conditions. Therefore, pilot frequency GAP measurement and switching in group calls area realized and downstream data loss of the terminal is avoided and data transmission reliability is kept.
