The invention discloses a data transmission system and method of point-to-point connection telecommunication equipment, which is characterized by the following: the lower telecommunication equipment connects primary higher telecommunication equipment and standby higher telecommunication equipment; the lower telecommunication equipment sends data to primary higher telecommunication equipment through ascending port; when the lower telecommunication equipment ascertains the higher communication is out of order, the higher telecommunication equipment is switched; the data is sent to the switched main higher telecommunication equipment by lower telecommunication equipment and ascending port which connects main higher telecommunication equipment. The invention realizes the reliability of data transmission net group, which improves the stability of telecommunication business.

The invention discloses a method and device for selecting cells to be switched at a switching preparatory stage. In the method, a source cell acquires resource state information of each adjacent cell, and each adjacent cell is classified into different load states in accordance with the resource state information of each adjacent cell; the source cell adjusts switching parameters corresponding to the adjacent cell in accordance with the load state of each adjacent cell; and when user equipment (UE) in the source cell needs to be switched, the source cell selects the cells to be switched of the UE in the adjacent cells in accordance with the adjusted switching parameters of each adjacent cell. By using the technical scheme disclosed in the invention, the appropriate cells to be switched can be selected and the switching success rate is improved.

The invention discloses a method for switching and controlling mobile communication networks, which is used to arrange a switching threshold from a first network to a second network under a connecting mode and the switching threshold from the first network to the second network under an idle mode for users' devices. The method comprises: firstly, judging if the users' devices are located in the connecting mode or not at present by the users' devices, executing the second step if the users' devices are located in the connecting mode, otherwise executing the third step, secondly, judging if thesignal quality of the second network satisfies the switching threshold from the first network to the second network under the connecting mode by the users' devices, executing the fourth step if the signal quality of the second network satisfies the switching threshold from the first network to the second network under the connecting mode, otherwise executing the first step, thirdly, judging if the signal quality of the second network satisfies the switching threshold from the first network to the second network under the idle mode, executing the fourth step if the signal quality of the secondnetwork satisfies the switching threshold from the first network to the second network under the idle mode, otherwise, executing the first step, and fourthly staring the switching from the first network to the second network by the users' devices. The technical scheme of the invention not only avoids Ping-pong switching between networks, but also can guarantee that the users' devices are preferentially parked on the second network simultaneously.
