Specific embodiment
In order to be clearer and more clear technical problems, technical solutions and advantages to be solved, tie below
Drawings and examples are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
Embodiment one
First embodiment of the invention provides a kind of localization method, is applied to terminal, the described method comprises the following steps:
S11 obtains terminal wake-up signal；
Specifically, the signal that terminal wakes up can be terminal starting-up signal, the signal that terminal screen is lit, or there is foreground
Signal or terminal that task is executed in terminal turn to the signal of high power operation from low power run.
S12 carries out network resident by 3GPP technology；
Network resident is carried out by 3GPP technology, including but not limited to 2G/3G/4G/NB-IoT/5G carries out network resident,
3GPP is mainly worked out based on GSM core net, and UTRA (FDD is W-CDMA technology, and TDD is TD-CDMA technology) is wireless
The third-generation technology specification of interface, the target of 3GPP are to realize by the smooth transition of 2G network to 3G network, guarantee WeiLai Technology
Backwards compatibility, support the roaming and compatibility between light networking and system.
S13 sends user Payload data to Cloud Server；
Internet-of-things terminal and cellular network base station communication, and communication registration is completed, into connection status.
Terminal sends Payload data to Cloud Server by resident network；Payload data (the Payload
Data) refer to the part data that recite information.Usually when transmitting data, in order to keep data transmission more reliable, original
Beginning data batchwise transfer, and certain auxiliary information is all added in the head and tail of every batch of data, such as this batch of data amount
Size, check bit etc. is equivalent in this way to initial data adds some housings in batches, these housings play mark and make
With so that initial data is not easy to lose.Batch of data adds its " housing ", is formed transmission list basic in transmission channel
Member is called data frame or data packet (some places data frame and data packet be not identical concept such as network transmission).These
The initial data of record information in data frame is exactly payload data, i.e. Payload data.
In order to keep location information more accurate, the data that terminal is sent after resident to Cloud Server, in addition to including user
It can also include local time zone information and current time information corresponding with time zone except Payload data.The information can be into
Terminal major edge calculating task of the one-step optimization based on position and time, time zone.

Calculate the location information obtained；
When Cloud Server receives user's Payload data, positional parameter acquisition request is initiated to cellular core network node, is looked into
Ask the present terminal presence information and the relevant parameter letter of cellular radio (cellular radio) of 3GPP core network element MME
Breath receives the positional parameter vector that core net node is returned to Cloud Server；Then Cloud Server is according to the parameter information of acquisition
It carries out the complicated position location computation of carrier-class (carrier grade) and multiple positioning planes is subjected to differencing, obtain
Location information；Cloud Server passes through the longitude and latitude and optional elevation information expressed with coordinate systems such as WGS-84, GCJ-2
UDP or TCP link is handed down to terminal.
It in core net node data deficiencies, optionally needs to obtain base station pond information, is such as obtained from MME.
The core net: simply, mobile network can be divided into three parts, base station sub-system, network subsystem
System and system support section such as safety management etc. these.Core network part is exactly to be located in network subsystem, core net
Main function is the call request or request of data that A mouthfuls are come up, and is routed on different networks.MME(Mobility
Management Entity) it is the key control node that 3GPP agreement LTE accesses network, it is responsible for the UE (User of idle mode
Equipment process, including relaying are notified from a phone call in positioning), and briefly MME is responsible for signaling processing part.
The location information is being locally stored and is executing location tasks using the location information by S15.
Terminal applies enter dormant state after using location data, to reduce power consumption to greatest extent.
The reduction of power consumption can be embodied by comparing with current existing GPS/AGPS scheme:
Comparative indices include processing time and operating current:
The internet-of-things terminal of 1.1GPS/AGPS scheme there are thermal starting, warm starting, be cold-started several scenes.Battery power supply
Internet-of-things terminal can not accomplish that GPS chip is normally opened, therefore thermal starting is not suitable for this scene.Therefore more to save power consumption
Warm starting for compare: TTFF index (primary positioning time) industry level average value was at 23.6 seconds or so, work
Electric current is above or below 50mA.
1.2 counterpart terminals of the present invention are after uplink Payload has been sent, it is only necessary under waiting under idle mode state
Cell message of the row containing latitude and longitude information is 3GPP agreement T3324 10 seconds a length of when most, and corresponding operating current is on 5mA
Under.
The localization method that the present embodiment is realized, working time shorten 50% or so, operating current and are reduced to original 1/10
Left and right；It is worked while power consumption is greatly reduced, operating time shortens with low current, the service life of battery can be greatly prolonged,
To increase the service life of terminal.
