Abstract: A positioning method and apparatus for a mobile terminal, and a mobile terminal. After a first time period elapses, a main processor obtains M pieces of reliable navigation data from N pieces of buffered navigation data of the mobile terminal, and obtains K pieces of buffered position change data of the mobile terminal. The main processor combines the M pieces of reliable navigation data and the K pieces of position change data, to obtain position information of the mobile terminal in the first time period. The N pieces of navigation data are obtained through calculation by using a satellite navigation signal of the mobile terminal that is received during the first time period. The K pieces of position change data are obtained through calculation by using data that is obtained through monitoring by a sensor of the mobile terminal during the first time period.

Abstract: A node selection method and apparatus are disclosed. The method includes: receiving a request message, where the request message is used to request to provide an installation package of a product required by a user; searching, based on the product information in the request message, a node state table for a target node corresponding to the product information, where the node state table includes at least one correspondence; and sending the request message to the target node, so that the target node builds the corresponding product installation package for the product required by the user (203). The method can quickly find the target node that can provide a service, to complete job dispatching, and improve job dispatching efficiency.

Abstract: Embodiments of this application relate to a cell access method and apparatus, and a device, and the method includes: obtaining a movement speed of a terminal; determining a signal strength offset value based on the movement speed; obtaining signal strength of a serving cell and signal strength of at least one neighboring cell, where the serving cell is a cell on which the terminal currently camps, and the neighboring cell is a cell in which the terminal can receive a signal; determining whether a sum of signal strength of a first neighboring cell in the at least one neighboring cell and the offset value is greater than or equal to a preset threshold; and if the sum of the signal strength of the first neighboring cell and the offset value is greater than or equal to the preset threshold, accessing, by the terminal, the first neighboring cell. The cell access method and apparatus and the device provided in the embodiments of this application can resolve a problem of frequent network disconnection of the terminal in a high-speed movement process, so that a call completion rate of the terminal can be improved.
