Technical field
The invention belongs to electronic information field, is related to mobile communication technology, more particularly to a kind of 5G Internet of Things electric power data
Acquisition terminal connection control method.
Background technology
Internet of things functional is realized using cellular technology, it is necessary to which congestion caused by solving extensive internet-of-things terminal access is asked
Topic.It is special in order to adapt to the demand for development of following 5G Internet of Things, it is necessary to strengthen existing LTE system machine type communication (MTC)
It is not that congestion control is strengthened.Congestion control is divided into congestion control caused by congestion control caused by core net and wireless network
System.
When core network congestion, E-UTRAN should be identified and be refused some low priorities MTC (Machine- in time
Type Communications) terminal access, to ensure the transmission of high priority terminal (including high priority MTC terminal).
For this reason, 3GPP is terminal introducing one, " Delay Tolerant " are indicated, when terminal is using this instruction, show that it can be in net
Longer delay is endured during network congestion.It should be noted that MTC applications are also multifarious, not all MTC applications all may be used
To endure longer delay, such as, for the sensing network of earthquake pre-warning, when network congestion, it is also necessary to allow as soon as possible
It accesses and transmits data.Therefore whether MTC applications are mapped to " on Delay Tolerant ", by operator in Non-Access Stratum
(NAS, Non-Access-Stratum) is configured.When core net is in congestion state, base station (eNB) can be by refusing or releasing
Bleed off those connections higher to time delay tolerance, and feed back a latency value EWT (Extended Wait Time,
Extend stand-by period, maximum 1800s).After terminal receives above-mentioned message, it can be opened in end side according to this stand-by period
A timer is moved, before timer expires, RRC (Radio Resource Control) is no longer initiated in corresponding MTC applications
Connection.Fig. 1 is connected under foundation and existing RRC connections with Fig. 2 for Initial R RC, the congestion after core network congestion without network
Control flow.Wireless side is directed to the control method of MTC device turn-on time, these schemes are transparent for application layer, even if

In E-UTRAN, network side can pass through limitation ACB (Access Class Barring, the access of access grade
Grade limits) realize access control, avoid congestion.LTE-A cells can broadcast a restriction factor and access level restriction time
(ACBT, Access Class Barring Time) (being carried in SIB2).When terminal accesses, terminal extracts a random number,
This random number and restriction factor are compared.If random number is less than restriction factor, terminal starts random access procedure, no
Then, terminal can be prevented from accessing within the access level restriction time.Existing lte-a system, has 16 access grades, one
As in the case of (nonemergency) TerminalAccessClass be 0-9.Since the new business such as MTC type (or terminal type) introduces,
Needs, which are impacted, in order not to the access to ordinary terminal is directed to MTC terminal micro-stepping control in access control process, can be existing
Having is strengthened on the basis of ACB mechanism, and new restriction factor EAB (Extended Access are introduced for MTC device
Barring, the extension access restriction factor) when core net or Wireless network congestion, network can be selected to mark EAB's
The access control of making choice property of terminal.EAB is broadcasted by SIB14, and access control parameter can be that UE is unit or one
Group UE is unit.Purpose is controlled to carry out the access of different stage to single or one group of MTC terminal.EAB mechanism purpose
It is on the premise of terminal AC number of levels is not expanded, additionally configures a set of control for new type terminal (or business) and join
Number, to play the purpose to MTC terminal micro-stepping control.EAB mechanism designs on the basis of existing ACB mechanism, can lead to
Cross the superposition to EAB and ACB to use, realize access congestion control.
And in electric system, Internet of Things is mainly used for the power information collection low to the insensitive rate requirement of time delay
Business, such as remote meter reading.This kind of terminal quantity is numerous, and distribution density is higher.Although honeycomb Internet of Things network side is directed to congestion
Certain enhancing has been done in control, but needs to take into account ordinary terminal and MTC internet-of-things terminals, and Internet of Things electric power terminal is particularly all
Access interference once occurs for phase reporting terminal, can increase the number of attempt of internet-of-things terminal access network and increase terminal activation etc.
Treat the time span accessed again, and then add power consumption, reduce terminal standby time (when 5G Internet of Things requires terminal standby
Between reach 10 years).
