Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an automatic selection method for a multi-operator network is proposed, which is applied to a user equipment, where the user equipment includes: the system comprises a polymerization card base plate, wherein patch cards of a plurality of operators are installed on the polymerization card base plate;
the method comprises the following steps:
102, acquiring a service type of user equipment, and determining a card-switching condition corresponding to the service type, where the card-switching condition is obtained by acquiring, by a server, a historical measurement report reported by the user equipment, an acquired historical real-time rate, and the service type, and multiple network indexes are recorded in the historical measurement report, where the multiple network indexes include: the method comprises the steps of establishing a mapping relation table between a plurality of network indexes and real-time rates according to a historical measurement report and a historical real-time rate, and determining corresponding card cutting conditions according to the mapping relation table and service types.
In order to set the card cutting condition scientifically and reasonably, the card cutting condition is set based on the service type, different service types have different requirements on network quality, for example, for large-flow equipment, the required network quality is high often, and for small-flow equipment, the requirement is low often, when the card cutting condition is met, the frequent card cutting is avoided, so that the scientific and reasonable setting of the card cutting condition is beneficial to keeping the service in the user equipment to operate effectively and stably.
Specifically, a mapping relation table is established according to a historical measurement report reported by user equipment and a collected historical real-time RATE, the established table relation is shown as follows, the historical measurement report comprises a plurality of other network indexes except that the historical measurement report does not comprise RATE (real-time RATE), the real-time RATE of the user equipment is obtained through a server to establish the mapping relation table comprising the mapping relation between RATE and CQI, wherein the value of the CQI is 0-15, the RATE requirement is determined through the service type, then the lowest CQI value and the lowest values of the other network indexes are determined, and the lowest values are used as a switching threshold value. And after the mapping relation table is established, the mapping relation table is issued to the user equipment through the server.
| CQI | SNR | SINR | RSRQ | RSRP | CSQ | RATE |
| 0 | … | … | … | … | … | … |
| 1 | … | … | … | … | … | … |
| … | … | … | … | … | … | … |
And step 104, periodically and interactively acquiring real-time data by the user equipment and the base station, judging whether a card switching condition is met or not according to a plurality of pieces of periodic data acquired in real time, determining a target operator network when the card switching condition is met, and switching the network of the user equipment to the target operator network.
In one embodiment, when the sampling CQI rate is lower than the lowest value issued by the server for continuous preset times (for example, 7 times), the card switching operation is triggered; when any one of the SNR, SINR, RSRQ, RSRP and CSQ values is lower than the reference value issued by the server for a preset number of times (for example, 7 times), the card cutting operation is triggered. The user equipment is handed over to the target operator network by sending a handover instruction (AT instruction).
According to the automatic selection method of the multi-operator network, the card cutting condition is set according to the service type of the user equipment, the card cutting condition is obtained by acquiring a historical measurement report reported by the user equipment and acquired historical real-time rate and service type through a server, a plurality of network indexes are recorded in the historical measurement report, a mapping relation table of the plurality of network indexes and the real-time rate is established, and then the corresponding card cutting condition is determined according to the mapping relation table and the service type.
In one embodiment, the establishing a mapping relationship table between a plurality of network indicators and a real-time rate according to the historical measurement report and the historical real-time rate, and determining a corresponding card-cutting condition according to the mapping relationship table and a service type includes: determining a network requirement corresponding to a service type, wherein the network requirement comprises: a minimum communication rate requirement and a delay requirement; converting the network requirement into a lowest CQI value, a lowest SNR value, a lowest SINR value, a lowest RSRQ value, a lowest RSRP value and a lowest CSQ value according to the network requirement and the mapping relation table; and determining a card cutting condition according to the lowest CQI value, the lowest SNR value, the lowest SINR value, the lowest RSRQ value, the lowest RSRP value and the lowest CSQ value.
The conversion of the corresponding network index value is carried out according to the network requirements corresponding to different service types, so that the lowest value of each network index value can be determined, and the card cutting condition is set based on the lowest value. The card cutting condition is set according to the network requirement corresponding to the service type, so that the card cutting condition can be more accurately determined, and the effective and stable operation of the service is kept.
Because the internet of things equipment cannot acquire the network quality of each operator at the same time, when the card switching condition is achieved at present and needs to be switched, the current operator is switched to another operator blindly, and if another operator network does not work, switching is performed again.
As shown in fig. 2, in an embodiment, the determining a target operator network when the card-switching condition is satisfied, and switching the network of the user equipment to the target operator network includes:
and step 104A, when the card-cutting condition is met, the server acquires the geographical position of the user equipment, acquires the current communication states and the corresponding operator networks of a plurality of other devices of the same service type within a preset range according to the geographical position, and acquires the corresponding historical communication states and the operator networks of the user equipment within the current time period.
In order to determine which operator network is selected as the card-cutting object, the quality of other operator networks needs to be obtained, so that the switched operator network not only can currently meet the communication requirement, but also needs to continuously provide stable service as much as possible, so that frequent switching of the operator networks can be avoided, and meanwhile, more stable service can be provided. The network states of the devices with the same geographic location and the same service type are often similar, so the server can obtain the current communication states of a plurality of other devices with the same service type in a preset range and the corresponding operator network as reference. In addition, for the same device, the communication states of the operator networks in a certain time period within a day are often similar, so the corresponding historical communication state and the operator network in the current time period can also be taken as reference.
And step 104B, the server acquires a mobile terminal interacting with the user equipment, the mobile terminal is close to the user equipment and interacts with the user equipment through code scanning, the server acquires a first time stamp of initiating a message and a second time stamp of receiving the message during interaction, and acquires the size of transmission data and an operator network during interaction between the mobile terminal and the user equipment.
When the mobile terminal and the user equipment perform close-range interaction, the network communication state of the operator corresponding to the mobile terminal can be used as a reference. Specifically, when the mobile terminal interacts with the user equipment, the server obtains a first timestamp of a message initiated by the mobile terminal and a second timestamp of a received message, and obtains the size of transmission data and an operator network used by the mobile terminal when the mobile terminal interacts with the user equipment. And evaluating which operator has a better communication state currently by counting the communication states of all mobile terminals interacting with the user equipment in the current time period and taking the operator network as a reference.
Considering that in the preset range, if there is no other device, or other devices are disconnected, only the current operator cannot be used, and it is impossible to determine which operator is the best operator to switch to. The current best operator can be more accurately evaluated by introducing the corresponding historical communication state of the user equipment in the current time period and the communication state of the operator network and the mobile terminal interacting with the user equipment, so that accurate switching is realized.
And step 104C, determining candidate operator networks according to the current communication states of the plurality of other devices of the same service type in the preset range and the corresponding operator networks, the corresponding historical communication states of the user equipment in the current time period and the operator networks, and the first time stamp, the second time stamp, the transmission data size and the operator networks.

By integrating the network quality evaluation of the three latitudes, more accurate candidate operator networks can be determined, so that the switched network can stably run for a longer time.
And step 104D, acquiring the current communication state of the candidate operator network, and if the current communication state meets a preset condition, taking the candidate operator network as a target operator network.
After determining the candidate operator network, switching to the candidate operator network, then acquiring the current communication state, and taking the candidate operator as the target operator network only if the current communication state meets the preset condition.

The method has the advantages that the network quality and the duration corresponding to each operator network are evaluated by using the network prediction model, so that the influence of each aspect on the operator network can be more accurately determined, and compared with a method for setting the weight, the method can obviously more accurately predict the conditions of each operator network, and is more favorable for selecting a proper operator network.
In one embodiment, the method further comprises:
