[0003] CSG cells are generally used as outdoor macro cells, that is, as a supplement to non-CSG cells, to enhance indoor coverage and reduce the load of outdoor macro cells to provide higher wireless service quality. Therefore, CSG cells are generally deployed in existing macro cells. However, the users who sign up to use the Femtocell in the same macro cell also change dynamically. There are unsubscribed users and new users. All CSG cells within the coverage of the macro cell are added to the neighbor relationship of the macro cell, and the system changes in time, which will lead to a continuous and huge workload

Embodiment Construction
[0030] figure 1 It is a schematic flow diagram of a method for CSG cell reselection according to an embodiment of the present invention, as shown in figure 1 As shown, the method for CSG cell reselection in this embodiment includes:
[0031] Step 101: The UE matches the CGI information of the macro cell where it is camped on with the neighboring cell CGI list in the CSG cell information where the UE has previously camped. take measurements;
[0032] Before this step, the method further includes: the UE camps on a CSG cell, obtains relevant information of the CSG cell, and saves the relevant information of the CSG cell to the CSG cell information (CsgHistoryInfo) where the UE has historically resided, and simultaneously writes In this way, the relevant information of the above-mentioned CSG cell will not be lost after the UE is powered off, and can still be read and used after the next boot;
[0033] Wherein, the relevant information of the CSG cell includes: CSG cell freque...

Disclosed is a method for reselecting a closed subscriber group (CSG) cell. The method comprises: matching, by a UE, CGI information about a macro cell in which the UE resides with a neighbour CGI list in historical residence information about a CSG cell of the UE, and when the matching is successful, measuring a frequency point of the CSG cell corresponding to the neighbour CGI list, the matching of which is successful; and when it is determined that the ID of a physical cell which is obtained by way of measurement is within the range of the ID of a CSG physical cell in the historical residence information about the CSG cell of the UE, measuring and evaluating the physical cell, and when it is determined that the physical cell conforms to measurement and evaluation conditions, selecting the physical cell as a resident cell. Also disclosed at the same time are a device for reselecting a CSG cell, and a storage medium.
Description
technical field [0001] The present invention relates to the technical field of Long Term Evolution (LTE, Long Term Evolution) mobile communication, in particular to a method and device for reselecting a Closed Subscriber Group (CSG, Closed Subscriber Group) cell. Background technique [0002] CSG is a concept introduced for home base stations. People who use home base stations are divided into some user groups. Users who are eligible to use home base stations to provide services are considered members of the user group. The user group composed of these members is called closed user group. [0003] CSG cells are generally used as outdoor macro cells, that is, as a supplement to non-CSG cells, to enhance indoor coverage and reduce the load of outdoor macro cells to provide higher wireless service quality. Therefore, CSG cells are generally deployed in existing macro cells. However, the users who sign up to use the Femtocell within the coverage of the same macro cell also chan...
