Embodiment 1

[0046] Such as figure 1 , a mobile network intelligent roaming selection method, comprising the following steps in sequence:

[0047] Step 1: Clear the PLMN list, scan all surrounding operator networks in the current environment, obtain the signal strength of each operator network, and update the signal strength of each operator network to the PLMN list;

[0048] Signal strength is the criterion for judging the priority of network operators. Generally speaking, the better the network strength, the better the network service quality.

[0049] Step 2: Select the operator network with the best signal strength in the PLMN list to establish a network connection;

[0050] Step 3: Periodically check the network service quality of the operator network in use; in this embodiment, the network service quality includes received signal quality, network delay, and packet loss rate;

[0051] If the following conditions are met, the network service quality of the operator's network is lower...

Embodiment 2

[0060] Such as figure 1 , a mobile network intelligent roaming selection method, comprising the following steps in sequence:

[0061]Step 1: Clear the PLMN list, scan all surrounding operator networks in the current environment, obtain the signal strength of each operator network, and update the signal strength of each operator network to the PLMN list;

[0062] Signal strength is the criterion for judging the priority of network operators. Generally speaking, the better the network strength, the better the network service quality.

[0063] Step 2: Select the operator network with the best signal strength in the PLMN list to establish a network connection;

[0064] Described step 2 is specifically:

[0065] Step 21: Reset the cellular network module;

[0066] Step 22: Select the operator network with the best signal strength in the PLMN list for network registration. If the registration is successful, perform network connection. If the registration is unsuccessful, select o...

Embodiment 3

[0084] Combining Topology Map - figure 2 The present invention is described in more detail:

[0085] 1)Smart Roaming Start - start the smart roaming function for the first time;

[0086] 2) Clear PLMN List——Clear the operator's PLMN list and make the list empty. If the PLMN is queried in the subsequent process, a new list will be created and the PLMN will be added to the list.

[0087] 3) Modem start / Restart——reset the cellular network module;

[0088] 4)Smart Roaming enable——judging whether to enable the smart roaming function, if not enabled, execute according to the normal network processing flow; if enabled the Smart Roaming function, execute the next step;

[0089] 5)Switching flag——judging whether it is currently in the process of operator switching, if it is in the process of switching, try to bind the PLMN of the corresponding operator, see step 6); if it is not in the process of switching, skip to step 7) step execution;

[0090] 6) Select next PLMN and use comma...

Abstract

The invention discloses a mobile network intelligent roaming selection method. The method comprises the following steps in order: step one, emptying a PLMN list, scanning all operator networks surrounding the current environment, acquiring signal intensity of each operator network, and updating the signal intensity of each operator network to the PLMN list; step two, selecting the operator networkwith the best signal intensity in the PLMN list to establish the network connection; step three, periodically checking the network quality of service of the operator network in current use; step four, judging whether a switchable operator network is existent in the PLMN list, if the switchable operator network is existent in the PLMN list, performing step two and forbidding the operator network before switching in the PLMN list, or performing the step one; and step five, continuously using the currently used operator network and performing the step three. By scanning the operator informationin the current environment through the background, the network state and like data are acquired, thereby selecting and switching to the optimal network according to the above state data.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a mobile network intelligent roaming selection method. Background technique [0002] Mobile data tariffs for European network operators are as low as 1GB-4 euros, a major development that has been included in EU consumer regulations and affects consumers, and more importantly, has a major impact on M2M applications. This means that traditional high-data applications, such as HVAC, BMS, CCTV, charging piles and retail terminals, can benefit from higher reliability roaming (multi-network) SIM cards. [0003] However, the roaming selection PLMN mechanism of these cards is often contrary to the more stable and high-quality PLMN of customers. Users need a customizable or more intelligent operator selection mechanism from the terminal side. [0004] SIM card types in Europe: [0005] 1)Single network--e.g.Vodafone [0006] These SIMS provide coverage on a single ne...
