Specific embodiment
For ease of understanding, with reference to the accompanying drawings of the specification, to network test terminal provided by the embodiments of the present application and system
It is described in detail.
Internet of Things is by application radio frequency identification (Radio Frequency Identification, RFID) technology, red
The information transmission equipments such as outer transmission device, global positioning system, honeycomb Internet of Things module, by the agreement of agreement, article and mutually
Networking connects, and information exchange and communication is carried out, to realize a kind of net of Weigh sensor, positioning, tracking, monitoring and management
Network.NB-IoT technical support low power consuming devices are connected in the cellular data of wide area network.EMTC technology has super reliable low time delay, branch
Mobility is held, can position and cost is lower.Both technologies are widely used in Internet of Things.Common Internet of Things application packet
It includes: smart meter reading, wisdom street lamp, car networking, shared bicycle etc..
It should be noted that network herein is primarily referred to as Internet of Things network, network operator is primarily referred to as deployment object
The operator of intranet network.Such as: the operator of deployment NB-IoT network or the operator for disposing eMTC network.
With the Scaledeployment that the Internet of Things of NB-IoT, eMTC network is applied, network operator and technology of Internet of things application
Person needs to assess the signal coverage condition of network using corresponding network test terminal, optimizes and application deployment etc..Mesh
Preceding testing scheme generally require profession network test terminal cooperate again profession test software, by profession tester into
Walking along the street survey or fixed test.The testing scheme is primarily present following problems:
(1), existing network test terminal is generally the network optimization instrument of profession, and universal functionality is complicated, at high cost.And this is specially
The network optimization instrument of industry needs the network optimization personnel of profession to operate, for common Internet of Things application project deployment personnel,
It is operated may be complex, therefore is not easy to its popularization and application.
(2), current network test terminal generally can only be in the NB-IoT network or eMTC network of certain operator
Some frequency range of one of network tested, versatility is poor.And Internet of Things application deployed position is wide, uses field
The complicated multiplicity of scape, it is at high cost and complicated for operation to obtain comprehensive network coverage data by current method.In addition,
NB-IoT or eMTC technology is to achieve the purpose that reduce network test terminal complexity, reduce power consumption in design, is cancelled or simple
Measurement report (Measurement Report, MR) machine that network test terminal carries out network signal measurement automatically and reports is changed
System, so that network operator can not obtain network coverage data by this way.To sum up, using existing mode network operator
The covering data of the Internet of Things networks such as more comprehensive NB-IoT or eMTC can not be obtained, network operator is also difficult to according to corresponding
Data take targetedly measure to improve covering.
(3), since Internet of Things application scenarios are various (such as basement, staircase, meagrely-populated area), network operator is very
Difficulty ensures that the network signal condition of all areas meets the demand of the Internet of Things application wait dispose or disposed.Network operator master
It to be disposed according to its backstage network coverage data to that will carry out or the network disposed is detected.And currently, acquired
Test data relevant to network quality not with the background network of operator covering database linkage so that operator is obtained
The network coverage data taken are not comprehensive, and accuracy is also difficult to obtain general warranty.And Internet of Things is applied and is different from mobile phone everywhere
Mobile, many applications are basic few mobile or do not move, and can not Active feedback network quality, once deployment, if network is believed
It is number bad, the influence for being difficult to eliminate will be generated to the application of client, so using corresponding network before Internet of Things application is disposed
Test terminal and system detect the signal of deployed position in advance, just seem very necessary.
