Abstract: A blind handover or blind redirection method and system are provided. The method includes: when a UE needs to perform blind handover or blind redirection, it is determined whether there is a history record of handover or redirection of the UE; and when there is the history record, a target cell which the UE is about to be blindly handed over to or blindly redirected to is selected according to the history record. In the disclosure, when a UE needs to perform blind handover or blind redirection, a base station selects a target cell through a stored history record of handover or redirection that the UE performed previously, so that the accuracy of target cell selection is improved, the success rate of blind handover or blind redirection is increased, and repeated processes of performing blind handover or blind redirection are reduced, thereby saving network resources, and meanwhile the occurrence probability of a call drop event is reduced, thereby improving user experience.

Abstract: A method for implementing soft handover based on a carrier aggregation technology, a base station and a terminal are disclosed. The method is applied in a scenario of complementary carrier coverage, and includes: a terminal and a base station simultaneously receiving and transmitting data through a plurality of cells corresponding to a plurality of member carriers by means of carrier aggregation, wherein one of the plurality of cells is a primary cell, and the rest are secondary cells; according to a measurement result of the terminal, the base station determining to switch one of the secondary cells to be the primary cell of the terminal, and marking the one of the secondary cells as a target secondary cell; and the base station maintaining a service connection between the terminal and the target secondary cell, and notifying the terminal to hand over a control signaling connection to the target secondary cell.

Abstract: The disclosure provides a method for switching between different network standards, which includes the following steps performed by a terminal: when switch is to be performed, sorting in a history record target cells corresponding to a source cell which the terminal is leaving, to form a search list, choosing the target cell from the search list and accessing the target cell. The disclosure further provides an apparatus for switching between different network standards. By means of the method and the apparatus of the disclosure, the rate of the switching between the different network standards is increased, the user experience is improved and the power consumption of the terminal is reduced.

Abstract: A terminal and the no-disturbance method thereof are provided, the method comprises: the terminal sends a power-off registration message to the network side, and completes the power-off registration process; in the case that a voice or short message calls the terminal, the network side returns a prompt that the terminal has been powered off to the calling party. By the processing above, it is ensured that in the case of initiating a call and sending short messages normally, the terminal can effectively prevent the user from being disturbed, and return a prompt that the terminal has been powered off to the calling party.

Abstract: A method and a terminal for determining soft handover diversity thresholds are disclosed in the present invention. In the above method, at first, a terminal determines a dynamical addition threshold of a diversity corresponding to the terminal according to the first predetermined information, wherein the first predetermined information comprises: carrier-to-interference noise ratios CINRs of all the base stations in the diversity, and parameters carried in downlink channel description messages that are received from base stations by the terminal; then, the terminal determines a dynamical deletion threshold for each base station in the diversity according to the second predetermined information respectively, wherein, for each base station, the second predetermined information comprises: CINRs for base stations in the diversity whose CINRs are greater than the CINR of the base station, and parameters carried in downlink channel description messages.

Abstract: The present invention discloses a method, system and apparatus for implementing short message network management, and the method includes: in carrying out a short message network management process, a master control terminal and a controlled terminal setting up a service connection between them; the master control terminal sending network management short messages to the controlled terminal through the service connection; and the controlled terminal carrying out corresponding processes according to contents of the received network management short messages. The problem of bad security and real-time of the short message network management in the prior art can be overcome by applying the present invention.
