In another exemplary embodiment, satisfying the preset judging condition for operator network handover includes that the current time reaches a time point corresponding to the preset time interval and the moving distance of the GNSS receiver is greater than a distance threshold. The preset time interval is 30 minutes, the configuration preset time interval is 12:15, and the distance threshold is 10 meters. When the current time reaches 12:45 and the moving distance of the GNSS receiver is greater than 10 meters, the differential age is obtained; when the current time reaches 12:45 but the moving distance of the GNSS receiver is less than 10 meters, the differential age is not obtained.

In the embodiment of the present application, the differential age is obtained only when the preset operator network switching judgment conditions are met, and then according to the differential age, it is determined whether the operator network switching conditions are met, and there is no need for real-time differential age and determination Whether it meets the operator's network switching conditions can avoid frequent acquisition of differential age and determine whether the operator's network switching conditions are met, reducing the occupation of GNSS receiver system resources.

In some possible implementations of the embodiments of the present application, S102 may include: calculating an average value of the difference ages obtained within a preset time period; and determining that the operator network switching condition is met when the average value is greater than a preset threshold.

In some possible implementations of the embodiments of the present application, the preset duration may be a period of time starting from a certain time point before the time point, and the time point may be the preset time point, or the time corresponding to the preset time interval point.

In some possible implementations of the embodiments of the present application, S102 may include: determining the network switching coefficient according to the differential age, the network quality of the first operator's network, and the network signal strength provided by the first operator's network; when the network switching coefficient is greater than In the case of the network switching coefficient threshold, it is determined that the operator network switching condition is met.

In some possible implementations of the embodiments of the present application, the average value of the differential age obtained during a preset period of time may be calculated according to the differential age, and then the average value, the network quality of the first operator's network, and the first operator's network The network signal strength provided by the supplier network is weighted and summed to obtain the network switching coefficient.

In some possible implementations of the embodiments of the present application, the average value of the differential age obtained during a preset period of time may be calculated according to the differential age, and then the average value, the network quality of the first operator's network, and the first operator's network The weighted average of the network signal strength provided by the supplier network is used to obtain the network switching coefficient.

In some possible implementations of the embodiments of the present application, weights corresponding to the average value of the differential age, the network quality of the first operator's network, and the network signal strength provided by the first operator's network may be set according to actual needs.

In some possible implementations of the embodiments of the present application, S103 may include: at least two operator networks corresponding to the embedded subscriber identification module (Embedded Subscriber Identification Module, eSIM) card included in the first operator network for the GNSS receiver In the case of the operator network in the network, switch to any operator network except the first operator network in at least two operator networks; the virtual user identity module included in the first operator network is the GNSS receiver (Virtual Subscriber Identification Module, vSIM) In the case of the operator network in the at least two operator networks corresponding to the card, switch to any operator network in the at least two operator networks except the first operator network; In the case where the first operator network is the operator network corresponding to the Subscriber Identification Module (SubscriberIdentification Module, SIM) card, switch to at least two SIM cards included in the GNSS receiver except the SIM card corresponding to the first operator network The carrier network corresponding to any other SIM card.

It can be understood that when the GNSS receiver is integrated with an eSIM card or configured with a vSIM card, since the eSIM card and the vSIM card can be configured with multiple numbers, multiple numbers can correspond to multiple operators, so there is no need to install a SIM card . When the GNSS receiver is integrated with an eSIM card or configured with a vSIM card, and the carrier network is switched, it can be switched directly in the network of multiple operators corresponding to the eSIM card or vSIM.

Exemplarily, the eSIM card integrated in the GNSS receiver corresponds to three operators, and the three operators are operator A, operator B, and operator C respectively. The current network of the GNSS receiver is the network provided by operator B, that is, the network provided by the first operator network is provided by operator B.

Based on the information sent by multiple GNSS receivers, the server generates time intervals, differential ages, and moving distances corresponding to each geographic location, and then sends the time intervals, differential ages, and moving distances corresponding to each geographic location to the GNSS receiver , so that the GNSS receiver performs differential data prediction and operator network switching based on the information.

In the following, the eSIM card integrated with the GNSS receiver, and the eSIM card corresponds to operator A, operator B, and operator C are taken as an example to describe the operator network switching method provided by the embodiment of the present application.

If the dial-up network cannot be successfully dialed, switch to the network provided by operator A and start dial-up networking. If the dial-up network cannot be successfully dialed, switch to the network provided by operator C to start dial-up networking. If the dial-up network cannot be successfully dialed, restart the wireless network. The module, then, periodically tries to dial up networking.

When the GNSS receiver can successfully dial up and stay on the network, the profile file corresponding to the geographic location where the GNSS receiver is located is sent to the server, including but not limited to the time interval corresponding to the geographic location, differential age, Movement distance threshold, network switching coefficient threshold, etc. After receiving the profile file, the server judges whether the profile file is consistent with the profile file corresponding to the geographic location stored in the server. If not, it means that the profile file corresponding to the geographic location exists Update, send the updated profile file corresponding to the geographic location to the GNSS receiver, and the GNSS receiver will perform differential data prediction and operator network switching according to the received profile file; if they are consistent, there is no need to send the corresponding geographic location to the GNSS profile file, the GNSS receiver performs differential data prediction and operator network switching according to the local profile file.

When the current time reaches the time point corresponding to the time interval in the profile file or the moving distance of the GNSS receiver is greater than the moving distance threshold in the profile file, obtain its differential age at the current location and the current first operator network , and then, according to the average value of the differential age obtained by calculating the preset duration, and then, the average value, the network quality of the first operator's network and the network signal strength provided by the first operator's network are weighted and summed to obtain Network switching coefficient, in the case that the calculated network switching coefficient is greater than the network switching coefficient threshold in the profile file, the carrier network is switched.

When the GNSS receiver cannot be successfully stationed in the operator's network that the network is switched to, continue to switch the operator's network until it can successfully dial up and station in the network.

When the GNSS receiver can successfully dial up and stay on the network, the profile file corresponding to the geographic location where the GNSS receiver is located is sent to the server. The profile file includes but is not limited to the time interval corresponding to the geographic location, differential age, and moving distance threshold and the network switching coefficient threshold, etc. After receiving the profile file, the server judges whether the profile file is consistent with the profile file corresponding to the geographic location stored in the server. If not, it means that the profile file corresponding to the geographic location has been updated, and sends The GNSS receiver sends the updated profile file corresponding to the geographic location, and the GNSS receiver performs differential data prediction and operator network switching according to the received profile file; if they are consistent, there is no need to send the profile file corresponding to the geographic location to the GNSS receiver , the GNSS receiver performs differential data prediction and operator network switching according to the local profile file.
