As shown in Fig. 2, the access control method of the communication terminal the following steps are included:
In step s101, data link request is sent according to current SIM card.
In an embodiment of the present invention, the embodiment of the present invention sends data link request, thus under current mobile network,
Whether detection communication terminal can establish data link with private network server.
In addition, the present invention is based on judging whether current SIM card has proprietary network access conditions under current mobile network,
Rather than it is based on communication terminal side, to improve the accuracy of control, will be described in detail below.
In step s 102, the Authority Verification information of the target network generated according to data-link request is received.
It is understood that the server of proprietary network can request feedback Authority Verification information according to data link, from
And identify under current mobile network, if there is access authority, will do it detailed description below.
In step s 103, if Authority Verification information is failure, the current mobile network of communication terminal is switched to
Preset mobile network, kainogenesis data connection request of laying equal stress on.
Specifically, if communication terminal can establish number with private network server at current network standard (2/3/4G)
According to link, then means the ability that current SIM card institute's signing service has access proprietary network under current network standard, that is, work as
There is access authority, without being switched to other mobile network under preceding mobile network.
If should be noted that at current network standard (2/3/4G), communication terminal and private network server establish number
When according to link, the refusal from private network server can be always received immediately, i.e. Authority Verification fails, then means current SIM card
Institute's signing service does not have the ability of access proprietary network under current network standard, i.e., does not have access under current mobile network
4G is such as switched to 3G or 2G to need to be switched to other mobile network by permission, so that there is access authority, without
User's manual switching while guaranteeing the dependable with function of communication, promotes user experience.
At this to the embodiment of the present invention based on judging whether current SIM card has proprietary network under the current mobile network
Access conditions, rather than it is based on communication terminal side, it is repeated with improving the principle of accuracy of control.
It specifically talks, a set of decision logic may be implemented in communication terminal side, to reach above-mentioned switching mobile network purpose,
When inquiring communications module work 4G mobile network such as communication terminal, just whether the data service communications of judgement and private network server
Often, if time-out forces communications module work 2G/3G mobile network without response or communication error, but there are many defects, lift
Under such as:
First, can not judge current erroneous whether due to short time wireless network environment it is bad caused by or server
Exception causes, and easily causes maloperation.
Second, if waiting timeout mechanism, waiting time bad control, waiting is too long, be easy to cause data service
Interaction time is elongated, poor user experience, but the waiting time is too short, then whether cannot exclude is due to single data link quality
It is bad, the problem of causing the long factor of call duration time to cause, so that erroneous judgement is generated, and communication terminal especially on the move, surrounding nothing
Gauze network environmental fluctuating is larger, and terminal is just more difficult to accurate judgement.
Therefore, in an embodiment of the present invention, in communications module, the embodiment of the present invention may determine that current SIM card exists
Whether there is proprietary network access conditions to automatically switch to 2G/3G mobile network if do not had under 4G network, so that working as
Preceding SIM card proprietary network access conditions, effectively improves the accuracy of access privilege control, avoids judging by accident and leading to maloperation, into
And reduce the situation of user experience.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further include: acquisition communication terminal
Communications data types；Target network is identified according to data type, to generate data link request.
It is understood that different industry fields can all have different limitations for the data interaction behavior of communication terminal.
For example, after communication terminal such as ammeter acquires or monitors data, if having thought, business is delivered, and communication terminal needs in power industry
Only communicate between specific electrical power services device and could complete；In another example communication terminal relevant to banking is such as
Various types of POS machine could complete industry after communication terminal only carries out data interaction with the server in bank's proprietary network
Business；For another example vehicle data to be treated itself just have several classes as each sensor of vehicle is monitored in vehicle-mounted industry
Related data, then communication terminal can only could complete data interaction with particular remote server, and multimedia system such as music,
The data of film, map etc. can directly be connected with Internet whenever and wherever possible, but cannot access particular remote server.Letter
Yan Zhi, the service that the communication terminal in different industries field data relevant for industry can only go access specified by proprietary network
Device, to guarantee the safety of communication.Therefore, the embodiment of the present invention determines identification target network according to communications data types, that is, sentences
Surely network is turned to, and then detects SIM card under current mobile network, if the access authority with proprietary network further mentions
The adaptability and accuracy of height control.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further include: detection Authority Verification
Time；If the Authority Verification time is greater than preset time threshold, and does not receive Authority Verification information, then current mobile network is cut
It is changed to preset mobile network.
Specifically, as shown in figure 3, since all data of communication terminal are transmitted by communications module, so logical
Believe that mould group is can to capture the IP data packet of communication terminal, so as to TCP (Transmission Control
Protocol, transmission control protocol) or UDP (User Datagram Protocol, User Datagram Protocol) connection behavior
It is analyzed.Wherein, communication data is after transmitting data to mobile network by air interface, then passes in proprietary network
Server, therefore judge whether specific proprietary network access ability, the embodiment of the present invention, which can screen out present air interface, is
No normal realization.
For example, if communication terminal request private network server establishes data-link at current network standard (2G/3G/4G)
When connecing, fail to receive reply immediately, if not having private network access ability, data can not reach server, so under normal circumstances,
It cannot all reply, if waiting request timed out at this time, take a long time, the Transmission Control Protocol regulation max-timeout time is
120 seconds, then mean the access authority of no proprietary network.
Wherein, in one embodiment of the invention, be greater than preset time threshold, and do not receive Authority Verification information it
Before, the method for the embodiment of the present invention further include: whether detection air interface links meet communication condition；If meeting communication item

Recognize information, and preset time threshold is 120 seconds.
It should be noted that communication condition and preset time threshold can by those skilled in the art according to the actual situation into
Row setting.For example, communication condition can be the confirmation message for receiving the communication protocol of current network, i.e. communications module is by IP number
When being sent to mobile network according to packet, need to use rlc protocol, module can receive after having sent upstream data from shifting
The confirmation packet of rlc layer in dynamic network, then illustrate that the link of air interface is unobstructed, and the unimpeded situation of link in eating dishes without rice or wine to connect
Under, if mould group still can not detect the response from private network server, illustrate the terminal under current network standard, no
The ability for having access private network.In another example 120 seconds that preset time threshold can provide the max-timeout time for Transmission Control Protocol, but
It is that it's not limited to that for preset time threshold, which is only for exemplary purposes, to be not specifically limited herein.
The access control method of communication terminal according to an embodiment of the present invention, in Authority Verification failure, by communication terminal
