Step S301, searching whether a GSM base station establishing connection with a GSM module in the dual-mode module exists or not and whether an NB-IoT base station establishing connection with an NB-IoT module in the dual-mode module exists or not, and obtaining a search result.
The module is composed of a chip and peripheral circuits required by the chip, such as a crystal, a memory, a power circuit and the like. The module is one of key parts for secondary development, has a complete and independent scanning function, and can be embedded into equipment in various industries such as mobile phones, computers, printers, assembly lines and the like. With the rise of the internet of things, modules are gradually widely used in various industries.
The dual-mode module is a GSM/NB-IOT module, and supports two modes, namely NB-IOT (Narrow-Band Internet of Things) and GSM (Global System for Mobile Communication). GSM is a so-called second generation (2G) mobile telephone system.
GSM and NB-IoT networks are not intercommunicated, service switching cannot be realized between the two networks, and only reselection (disconnected network reconnection) can be realized. In order to enable the dual mode module to switch between the NB-IOT network and the GSM network, an NB-IOT network searching module, a GSM network searching module, and a result analyzing module are provided in the terminal side device 1 (as shown in fig. 6). The NB-IOT network searching module searches a base station which can be connected with the NB-IoT module in the dual-mode module, the GSM network searching module searches a base station which can be connected with the GSM module in the dual-mode module, and the result analyzing module analyzes whether the dual-mode module is connected with the GSM and NB-IOT base stations or not currently, so that a searching result is obtained. It should be noted that the order in which the dual mode module searches for the base stations to establish a connection is not required.
Specifically, the search result includes four situations, including that the dual-mode module is not connected with the GSM base station and the NB-IoT base station, the dual-mode module is connected with the GSM base station, the dual-mode module is not connected with the NB-IoT base station, the dual-mode module is not connected with the GSM base station, the dual-mode module is connected with the NB-IoT base station, and the dual-mode module is connected with the GSM base station and the NB-IoT base station.
Step S302, selecting the network of the dual-mode module between a GSM network and an NB-IoT network according to the search result and a preset priority rule to obtain a selection result, and sending the selection result to network side equipment so that the network side equipment can switch the network of the dual-mode module between the GSM network and the NB-IoT network according to the selection result.
Preferably, the priority rule is that the NB-IoT network search has a higher priority than the GSM network search; the step of selecting the network of the dual-mode module between the GSM network and the NB-IoT network according to the search result and the preset priority rule to obtain a selection result comprises the following steps:
when the search result comprises that the dual-mode module is connected with the GSM base station and the dual-mode module is not connected with the NB-IoT base station, in an area covering the NB-IoT network, the selection result comprises switching the network of the dual-mode module from the GSM network to the NB-IoT network; or,
when the search result includes that the dual-mode module is not connected with the GSM base station and the dual-mode module is connected with the NB-IoT base station, if the NB-IoT network fails, the selection result includes that the network of the dual-mode module is switched from the NB-IoT network to the GSM network in the area covering the GSM network.
The method comprises the steps of presetting the NB-IOT network search priority higher than that of the GSM network in a result analysis module of terminal equipment, and executing different connection strategies according to different search results to obtain a selection result.
Specifically, the selection result includes two situations, including the network of the dual mode module switching from the GSM network to the NB-IoT network and the network of the dual mode module switching from the NB-IoT network to the GSM network. That is, the embodiment of the present application is only applied to the case where the network of the dual mode module needs to be switched between the GSM network and the NB-IoT network, and in the case of the above four search results, only two cases may occur and need to be switched between the GSM network and the NB-IoT network, and the rest cases are not considered because the network does not need to be switched.
When the search result includes that the dual-mode module establishes connection with the GSM base station and the dual-mode module does not establish connection with the NB-IoT base station, the network of the dual-mode module is switched from the GSM network to the NB-IoT network in consideration of the advantages (low power consumption, large connection, and the like) of the NB-IoT network, and the following scenarios are included.
Scene 1: and when the original GSM network fails, the network of the dual-mode module is switched from the GSM network to the NB-IoT network in the area covering the NB-IoT network.
Scene 2: in the area only covering the GSM network and not covering the NB-IoT network, the dual-mode module can only be connected with the GSM network, when the area where the dual-mode module is located covers the NB-IoT network and the GSM does not quit, the area where the dual-mode module is located simultaneously has the GSM network and the NB-IoT network, and the network of the dual-mode module is switched from the GSM network to the NB-IoT network.
Scene 3: when the dual-mode module moves from the area with only the GSM network to the area covered by both the GSM network and the NB-IoT network, the network of the dual-mode module is switched from the GSM network to the NB-IoT network.
Scene 4: when the dual-mode module moves from the area with only the GSM network to the area with only the NB-IoT network, the GSM network is disconnected, and the network of the dual-mode module is switched from the GSM network to the NB-IoT network.
And when the search result comprises that the dual-mode module is not connected with the GSM base station and the dual-mode module is connected with the NB-IoT base station, switching the network of the dual-mode module from the GSM network to the NB-IoT network, wherein the following scenes are included.
Scene 5: when the dual-mode module is connected with the NB-IoT network and is in a region where both the GSM network and the NB-IoT network exist, if the NB-IoT network fails, the network of the dual-mode module is switched from the NB-IoT network to the GSM network.
Step S303, judging that the selection result is to switch from the GSM network to the NB-IoT network or from the NB-IoT network to the GSM network, and if the selection result is to switch from the GSM network to the NB-IoT network, executing step S304; if the selection result is that the NB-IoT network is switched to the GSM network, the step S307 is executed.
Step S304, judging whether the code number of the Internet of things of the dual-mode module belongs to the HLR of the GSM network, if so, executing step S305; if not, go to step S306.
Step S305, controlling the dual-mode module to reserve the GSM network, and ending the process.
And S306, routing the Internet of things code number of the dual-mode module to the HLR of the NB-IoT network, and controlling the network of the dual-mode module to be switched from the GSM network to the NB-IoT network.
Step S307, judging whether the Internet of things code number of the dual-mode module belongs to the HLR of the NB-IoT network, if so, executing step S308; if not, go to step S309.
Step S308, controlling the dual-mode module to reserve the NB-IoT network, and ending the process.
Step S309, the Internet of things code number corresponding to the dual-mode module is routed to the HLR of the GSM network, and the network of the dual-mode module is controlled to be switched from the NB-IoT network to the GSM network.
Preferably, the dual-mode module corresponds to a card slot, and the card number in the card slot corresponds to an internet of things code number. The dual-mode module is pre-configured with an Internet of things code number, and a card slot of the dual-mode module can be arranged on the NB-IoT module or the GSM module. The dual-mode module is a single card and single number, and the network of the dual-mode module is switched by judging the attribution of the Internet of things code number of the dual-mode module.
The network side device is a core network side, and includes an SGSN (Serving GPRS support node) and an HLR (Home Location Register). The GSM base station and the NB-IoT base station are respectively connected with the corresponding network side equipment, and the network side equipment controls whether the corresponding base station is connected with the dual-mode module. The GSM base station and NB-IoT base station are the wireless side used for all or part of the fixed users to access the exchange, such as BSC/RNC, BTS/NodeB, etc., in a wireless manner. The network side device is a switching side, and the switching side is used for the side responsible for switching user data, and includes CS and PS domains, such as MSC, SGSN, GGSN, HLR, and the like.
The SGSN is used as an important component of the packet domain equipment of a GPRS/WCDMA (TD-SCDMA) core network of the mobile communication network, and mainly finishes the functions of routing forwarding, mobility management, session management, logical link management, authentication and encryption, ticket generation and output and the like of packet data packets.
The HLR is a systematic data center, which stores all the information of the location information, service data, account management, etc. of the mobile subscribers signed up at the HLR, and can provide the inquiry and modification of the location information of the subscribers in real time, and realize various service operations including location updating, call processing, authentication, supplementary services, etc. to complete the mobility management of the subscribers in the mobile communication network.
After the network side device receives the selection result sent by the terminal side device, it needs to first determine whether the selection result is switched from the GSM network to the NB-IoT network or from the NB-IoT network to the GSM network.
If the selection result is to switch from the GSM network to the NB-IoT network, based on the scenarios 1 to 4, when the dual-mode module is connected through the GSM network, the SGSN of the network-side device corresponding to the GSM base station may determine whether the internet-of-things code number of the dual-mode module belongs to the HLR of the GSM network. If so, controlling the dual-mode module to reserve the GSM network, namely, enabling the card slot of the Internet of things code number of the dual-mode module to be in the GSM module. If not, the card slot of the Internet of things code number of the dual-mode module is not in the GSM module, and the Internet of things code number of the dual-mode module is routed to the HLR in the NB-IoT network through the SGSN of the network side device corresponding to the GSM base station, so that authentication is realized, and the network of the dual-mode module is switched from the GSM network to the NB-IoT network. Note that, at this time, no inter-network settlement is involved.
If the selection result is that the NB-IoT network is switched to the GSM network, when the dual-mode module is connected through the NB-IoT network, the SGSN of the network side equipment corresponding to the NB-IoT base station can judge whether the Internet of things code number of the dual-mode module belongs to the HLR of the NB-IoT network. If so, controlling the dual-mode module to reserve the GSM network, namely, enabling a card slot of the Internet of things code number of the dual-mode module to be located in the NB-IoT module. If not, the card slot of the Internet of things code number of the dual-mode module is not located in the NB-IoT module, and the Internet of things code number of the dual-mode module is routed to an HLR in a GSM network through an SGSN of network side equipment corresponding to the NB-IoT base station, so that authentication is achieved, and the network of the dual-mode module is switched from the NB-IoT network to the GSM network. Note that, at this time, no inter-network settlement is involved.
According to the method for switching the network of the dual-mode module between the NB-IOT network and the network, the terminal side equipment designs a network selection strategy, the network side equipment routes the code number of the Internet of things and the method for transforming the SGSN of the network side equipment is adopted.
