Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] Functional Overview

[0026] Considering that the network selection method in the related art will complicate the network selection process and reduce the registration efficiency, the present invention provides a network selection method and device based on a shared network. According to the present invention, when the AS reports the searched available PLMN list, if it is a PLMN belonging to the same shared cell, the shared information is reported at the same time when the PLMN is reported, so that when selecting a PLMN, the shared cell information can be used to give priority to Other PLMNs that share the same cell can register without re-resident, thereby simplifying the network selection p...

Abstract

The invention discloses a network selection method and a device based on a shared network. The network selection method based on a shared network comprises: when a mobile station (MS) fails to register to a first public land mobile network (PLMN), searching whether a first PLMN assembly exists in a first selection level belonging to the first PLMN, wherein, the first PLMN assembly comprises one or a plurality of PLMNs positioned in the same shared cell with the first PLMN; if the first PLMN assembly is found, selecting a PLMN from the first PLMN assembly for registering. Thus, when PLMN is selected, the shared information can be used, other PLMNs belonging to the same shared cell are selected preferably without re-lingering, so that the network selection process is simplified, and register efficiency can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a network selection method and device based on a shared network. Background technique [0002] In order to effectively utilize resources and save operating costs, multiple operators may share the same access network. For example, China is currently advocating that multiple mobile operators share the same wireless resource system as much as possible. Therefore, the same cell can belong to multiple operators, such a cell is called a shared cell for short, and such a network is called a shared network. When a mobile terminal searches or resides in a certain cell, if it is a shared cell, the mobile terminal can use the information of multiple operators provided by the shared cell to optimize the PLMN selection and registration process. [0003] According to the PLMN selection specification (see TS (Technical Specification, technical specification) 23.122 of 3GPP (Third Generation ...
