Embodiment 1

[0024] refer to Figure 1-Figure 2 As shown, the embodiment of the present invention provides a terminal network access method, the method includes steps S101-S102:

[0025] S101. Match the public land mobile network with the radio-side broadcast PLMN of the target network and the core network-side PLMN in sequence according to the priority order of RPLMN, HPLMN, and EHPLMN until the matching is successful.

[0026] When the terminal chooses to join the network, it first obtains the registered public land mobile network RPLMN stored in the terminal memory, and then matches with the wireless side broadcast PLMN and the core network side PLMN of the target network respectively. If the wireless side broadcast PLMN or the core network side PLMN match fails , then reacquire the attributable public land mobile network HPLMN stored in the subscriber identity card, continue to match with the wireless side broadcast PLMN of the target network and the core network side PLMN, if the matc...

Embodiment 2

[0033] refer to image 3 , the terminal first accesses the eMTC network, and then accesses the LTE network. The first five digits of the obtained IMSI of the public land mobile network are used as the target PLMN to match with the wireless side broadcast PLMN and the core network side PLMN of the target network respectively.

[0034] S201. When the terminal accesses the eMTC network for the first time, obtain the RPLMN in the terminal memory as the target PLMN. Since the terminal accesses for the first time, the RPLMN is empty and the matching fails.

[0035] S202. Select to obtain the HPLMN in the user identification card, obtain HPLMN=46006 according to the first five digits of the IMSI, and judge whether the HPLMN matches the target network PLMN. Since the radio side broadcast PLMN of the eMTC is 46001 and 46006, the core network side PLMN is 46006. It can be seen that the matching can be successful on both the wireless side and the core network side.

[0036] S203. The t...

Embodiment 3

[0042] refer to Figure 4 , the terminal first accesses the LTE network, and then accesses the eMTC network. The first five digits of the obtained IMSI of the public land mobile network are used as the target PLMN to match with the wireless side broadcast PLMN and the core network side PLMN of the target network respectively.

[0043] S301. When the terminal accesses the LTE network for the first time, obtain the RPLMN in the terminal memory as the target PLMN. Since the terminal is accessing for the first time, the RPLMN is empty and the matching fails.

[0044] S302. Select to obtain HPLMN, obtain HPLMN=46006 according to the first five digits of the IMSI, and judge whether the HPLMN matches the target network PLMN. Since the wireless side broadcast PLMN of LTE is 46001 and 46006, the core network side PLMN is 46001. It can be seen that the matching is successful on the wireless side, but failed on the core network side.

[0045] S303. Obtain EHPLMN=46001, continue to match ...

Abstract

The invention discloses a method and device for a terminal to access a network, and relates to the technical field of communication, and is used for providing a method for the terminal to normally access the network in various network systems. The method comprises the steps: sequentially performing the matching of a PLMN (Public Land Mobile Network) with a radio side broadcast PLMN of a target network and a core network side PLMN according to a priority order from an RPLMN (Registered Public Land Mobile Network), an HPLMN (home public land mobile network), and an EHPLMN (equivalent local public land mobile network) until the matching is successful, wherein the RPLMN is stored in a terminal memory, the HPLMN and the EHPLMN are stored in an SIM memory; executing a network access process andwriting a successfully matched PLMN into a local terminal memory as a new RPLMN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal network access method and device. Background technique [0002] With the development of information technology, the application of Internet of Things technology in various industries has become more in-depth. According to a research report released in 2016, there will be 28 billion connections in the world by 2021, of which 15.7 billion connections will be the Internet of Things, and there will be 1.5 billion Internet of Things connections using mobile cellular technology, accounting for about 10. %. Narrowband Internet of things (NB-IoT) based on mobile cellular networks has attracted more and more attention because of its wide coverage and good connectivity. [0003] Long Term Evolution-enhanced machine type of communication (LTE-eMTC) is a low-power wide-area IoT access technology based on LTE network design. Compared with the traditional LTE netwo...
