技术领域technical field
本发明涉及终端以及核心网领域中的漫游网络接入技术，尤其涉及一种漫游网络的接入方法、装置及系统。The present invention relates to a roaming network access technology in the field of terminals and core networks, in particular to a roaming network access method, device and system.
背景技术Background technique
目前，终端在更新漫游网络时，一般按照3GPP规定的标准方案，基于数据卡中记录的运营商控制公共陆地移动网络(OPLMN，OperatorControlledPublicLandMobileNetwork)列表进行漫游网络的更新。但在实际过程中，由于数据卡中记录的OPLMN信息往往无法及时更新，这导致用户无法根据新漫游地的运营商签约信息进行选网。At present, when updating the roaming network, the terminal generally updates the roaming network based on the Operator Controlled Public Land Mobile Network (OPLMN, Operator Controlled Public Land Mobile Network) list recorded in the data card according to the standard solution specified by 3GPP. However, in the actual process, because the OPLMN information recorded in the data card is often not updated in time, this makes it impossible for the user to select a network based on the operator's contract information in the new roaming location.
对于上述问题，现有技术主要通过在终端侧预制文件，并根据该预制文件定制的内容进行选网，但是，该预制文件缺乏及时更新机制，且该预制文件定制的选网方式非标准化，因此，这种方法通常需要终端做非标准修改。For the above problems, the existing technology mainly prefabricates the file on the terminal side, and selects the network according to the content customized by the prefabricated file. However, the prefabricated file lacks a timely update mechanism, and the network selection method of the prefabricated file is not standardized. , this method usually requires non-standard modification of the terminal.
目前，已有厂家提出在终端中预存已签约漫游服务网络的系统识别码列表，当终端在漫游地捕获到该网络的导频信号后，读取所述导频信号对应的系统识别码。但该方法同样需要在终端侧预存系统识别码列表对应的漫游运营商，但在实际过程中，终端侧往往无法及时更新该系统识别码列表对应的漫游运营商。At present, some manufacturers have proposed to pre-store the system identification code list of the subscribed roaming service network in the terminal, and when the terminal captures the pilot signal of the network while roaming, read the system identification code corresponding to the pilot signal. However, this method also needs to pre-store the roaming operator corresponding to the system identification code list on the terminal side, but in the actual process, the terminal side often cannot update the roaming operator corresponding to the system identification code list in time.
与此同时，也有厂家提出基于3GPP中7号信令的漫游选网策略，该方法实时性较好，但上述基于7号信令的漫游选网策略，需要在不同运营商和终端之间进行互通性测试，实施成本较大。At the same time, some manufacturers have proposed a roaming network selection strategy based on SS7 in 3GPP. This method has better real-time performance, but the above-mentioned roaming network selection strategy based on SS7 needs to be carried out between different operators and terminals. Interoperability testing, the implementation cost is relatively large.
