Description
Technical Field
The invention relates to the field of data communication, in particular to a method for improving wireless access reliability and an access management server.
Background
In the mobile vehicle-mounted scene applying the dual 3G/4G uplink access, the network access method can be simultaneously connected with the networks of two operators, and backup and switching of an uplink network are formed. The method can well meet the application requirements of the same device for bearing various different private line services, for example, one sim (Subscriber identity Module) card provides a common passenger internet service; and another sim card can provide private network services with high security level at the same time.
But also presents higher requirements and challenges for 3G/4G uplink access: how to guarantee the preferential access to 4G under the condition of 3G/4G coverage of the vehicle-mounted product? How can advance access to a 4G network? How to guarantee 4G network stability and high bandwidth?
At present, three operators in China provide 3G/4G network systems as follows: 4G of UNICOM: TD-LTE, FDD-LTE; telecommunication 4G: TD-LTE, FDD-LTE; and 4G movement: TD-LTE; the mode of the Unicom 3G network is WCDMA; the mobile 3G network mode is TD-SCDMA; the 3G standard of telecommunications is CDMA 2000. In terms of speed, the downlink rate and the uplink rate of the TD-LTE are 100Mbps and 50Mbps, respectively, while the downlink rate and the uplink rate of the FDD-LTE are 150Mbps and 40Mbps, respectively, which are not much different in speed. The downlink rate and the uplink rate of TD-SCDMA are respectively 2.8Mbps and 2.2Mbps, the downlink rate and the uplink rate of CDMA2000 are respectively 3.1Mbps and 1.8Mbps, the downlink rate and the uplink rate of WCDMA are respectively 14.4Mbps and 5.76Mbps, under a mobile vehicle-mounted environment, mobile vehicle-mounted equipment actively registers in a 3G/4G network, and the provided management service basically ensures internet access service. In the high-speed moving process, the traditional 3G/4G registration switching is controlled by an operator, but the following disadvantages exist:
the first problem is that:
in the moving process of the mobile vehicle-mounted equipment, if the mobile vehicle-mounted equipment enters a telecommunication 3G mode, the mobile vehicle-mounted equipment cannot be actively registered in telecommunication 4G. Normally, the 4G network can only be entered after the mobile terminal moves to the signal coverage of only 4G and then re-initiates the associated registration. When the mobile vehicle-mounted equipment is in a 3G state, the transmission rate of the whole network is low, the synchronous transmission of authentication data to the mobile vehicle-mounted equipment is seriously influenced, and meanwhile, the bandwidth congestion is caused, and the internet surfing experience is poor.
The second problem is that:
in the moving process of the mobile vehicle-mounted equipment, if the mobile vehicle-mounted equipment enters a Unicom 3G mode and a network is in a non-idle state, the mobile vehicle-mounted equipment cannot be actively registered to Unicom 4G. Normally, the 4G state can be entered only when the mobile vehicle-mounted device is idle. And the network data transmission can be ensured to be more efficient only when the 4G state is recovered. And in the default existing operator coverage, the 3G/4G signal coverage cannot fully guarantee the access reliability.

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.
An aspect of the embodiments of the present invention is to provide a method for improving wireless access reliability, which is applied in an access management server, as shown in fig. 1, and includes the following steps:
s101, dividing the satellite navigation precision of a vehicle driving area;
the satellite navigation system may be a GPS (global positioning system) or a beidou satellite positioning system.
Taking GPS as an example:
longitude 0.00001 degrees (one hundred thousandth of a degree, 0 ° 0'0.036") corresponds to a distance of about 1 meter from the surface of the earth at the equator, but 0 meter at the north-south pole. Latitude 0.00001 degrees corresponds to a distance of about 1 meter from the earth's surface anywhere on the earth's surface. Therefore, the minimum scale of the device side GPS itself is 0-0.1 meters.
The error between the GPS module and the satellite communication system is determined by the GPS module specification and the signal strength, the embodiment of the invention can adopt a consumption grade GPS and a non-industrial purpose GPS, and the error range is 1-20 meters when the GPS signal is available according to the module specification. This error is unavoidable and the coverage of a 3G base station is not less than 20 m by 20 m, and is therefore tolerable.
According to the algorithm, the area needs to be divided, and in the dividing process, the area cannot be accurately divided to 0.1 meter, and the area does not need to be divided to a scale with a size as small as that, so that the area is inevitably larger than 0.1 meter. This necessarily causes a problem in that fig. 2 is a schematic view of a region in which point a does not fall within the scale, and is recorded as point C by comparing the value of point C with the divided region. Point B falls outside the scale and is considered invalid and no recording is made.
In a specific implementation process, the region division may be performed according to actual requirements, for example, each region range may be no more than 500 meters by 500 meters; the error caused by the earth curved surface is far smaller than the error between the GPS module and the satellite communication system and can be ignored; for the error of dividing the longitude and latitude square areas, the finer the division of one area is, the smaller the error is.
S103, determining the longitude and latitude of each divided region;
s105, updating the access frequency band state of the driving area corresponding to the driving vehicle according to the operation event of the driving vehicle in each area in the nth access frequency band in the period T,
s107, acquiring a state value according to the weighted value of the access frequency band state, wherein n is a natural number more than or equal to 2;
s109, determining the access frequency band corresponding to each region according to the state value;
s111, receiving a first longitude and a first latitude of a first running vehicle reported by the first running vehicle;
s113, determining a first area to which the first running vehicle belongs according to the first longitude and the first latitude;
and S115, sending a first access frequency band corresponding to the first area at the current moment to the first running vehicle, so that the first running vehicle processes the access frequency band used by the first running vehicle at the current moment according to the first access frequency band.
Optionally, step S105 specifically includes:
in a period T, when a second traveling vehicle traveling in a first area is successfully switched from a first access frequency band to a second access frequency band, recording a first access frequency band state in which the first area corresponding to the second traveling vehicle is located, and giving a first weight value to the first access frequency band state, when a third traveling vehicle traveling in the first area transmits data in the first access frequency band, recording a second access frequency band state in which the first area corresponding to the third traveling vehicle is located, and giving a second weight value to the second access frequency band state, when a fourth traveling vehicle traveling in the first area fails to be switched from the first access frequency band to the second access frequency band, recording a third access frequency band state in which the first area corresponding to the fourth traveling vehicle is located, and giving a third weight value to the third access frequency band state, and when a fifth running vehicle running in the first area sends data in the second access frequency band, recording a fourth access frequency band state of the first area corresponding to the fifth running vehicle, and giving a fourth weight value to the fourth access frequency band state.
In one embodiment X of the present invention, the mapping relationship between the area division of GPS and the 3G/4G state is shown in Table 1:
| region(s) | GPS longitude | GPS latitude | 3G/ |
| A | |||
| 1 | 1 | 0 | |
| |
1 | 2 | -1 |
| |
1 | 3 | 1 |
| |
2 | 1 | 0 |
| |
2 | 2 | 0 |
| |
2 | 3 | 0 |
| |
3 | 1 | 0 |
| |
3 | 2 | 0 |
| I | 3 | 3 | 0 |
TABLE 1
GPS longitude and latitude: represents a certain area;
3G/4G state: the 3G/4G state of a certain area is represented, and the value is int type;
0: representing an unknown state;
greater than 1: represents 4G;
less than 1 and greater than 0: represents 3G;
initializing the corresponding relation:
making longitude and latitude division according to the driving range of the vehicle;
the 3G/4G state is initialized to 0;
updating events according to the corresponding relation:
the frequency band switching fails, and the event is represented as A;
the frequency band switching is successful, and an event is represented as B;
the frequency band is 3G when the running vehicle transmits data in real time, and the event is represented as C;
the frequency band is 4G when the running vehicle transmits data in real time, and the event is represented as D;
the current 3G/4G state value is Y
The algorithm for z-value in one embodiment of the invention is as follows:
weight of each event:
when A occurs, the high probability event indicates that the current area is 3G, so the weight setting is 10;
when B occurs, the high probability event indicates that the current region is 4G, and therefore the weight is set to 5, but a is more illustrative of the problem than the a event, and therefore is set to be smaller than a;
when C occurs, the current real-time transmitted GPS-3G/4G is 3G, and is set to be 1 less than D;
when D occurs, the probability indicates that the 4G state is currently available, so the weight is set to 2, which is greater than C;
z＝-10+5+1+2＝-2。
step S107 specifically includes: and calculating a state value corresponding to the state according to the first weight value, the second weight value, the third weight value and the fourth weight value.
In the above-mentioned embodiment X of the present invention, if the first weight value is 10, the second weight value is 5, the third weight value is 1, and the fourth weight value is 2, the final state value is: -10+5+1+2 ═ 2. Wherein, the negative value indicates that the frequency band switching failure event has the opposite meaning to that indicated by other events.

Optionally, step S115 specifically includes:
and when the state value is larger than 1, sending the 4G frequency band corresponding to the first area at the current moment to the first running vehicle, so that the first running vehicle can process the access frequency band used by the first running vehicle at the current moment according to the 4G frequency band.
Optionally, step S115 specifically includes:
and when the state value is greater than 1, sending the 4G frequency band corresponding to the first area at the current moment to the first running vehicle, so that when the access frequency band used by the first running vehicle at the current moment is a 3G frequency band, switching the 3G frequency band used by the first running vehicle at the current moment according to the 4G frequency band, and sending a switching success event or a switching failure event to the access management server.
