Embodiment 3
The present embodiment is according to an alternative embodiment of the invention, for combining different scenes to carry out specifically the application
Bright, the present embodiment includes multiple specific embodiments：
Specific embodiment 1：
By taking long term evolution (Long-Term Evolution, referred to as LTE) eMTC systems as an example, the present embodiment description
EMTC access nets are directed to the RRC connections control for the real time business terminal for having used big coverage enhancement rank, and access net is obtained from the sides UE
Take service feature information；
Fig. 4 is the protocol procedures figure of this specific embodiment of the invention 1, and detailed description is seen below：
Embodiment precondition is as follows：
EMTC accesses net, and base station deployment, LTE access net system bandwidth are 10MHz altogether with LTE accesses net, and eMTC access nets are adopted
It is deployed in LTE access net system bandwidth with inband (in frequency range) mode.Assuming that high load capacity before eMTC access meshes, empty
Not busy interface-free resources are less, although a small amount of high rate user can also be received, can not bear high rate user and use larger covering
The other pattern of booster stage.The real time business type of UE is video conversation.
Step 401.UE, which is determined, to initiate random access in current area, establish and access the connection of net, UE is according to oneself
Measurement result in current area, using coverage enhancement rank 2, PRACH repetition factors 32 initiate random access.
Step 402.UE carries service feature information in message 3, and the service feature information can there are many form, examples
Such as：
(1) QCI (Qos class identifier) grade：At present 9 QCI have been divided in the existing QCI mechanism of LTE system
Rank, wherein QCI-4 represent video conversation business, in the present embodiment, the serial number of QCI-4 can be carried in message 3；
(2) or the parameter of business model, for example, including：The size of data packet, the arrival interval of data packet are arrived
The maximum scheduler latency or forward delay interval that can be tolerated up to period, data packet；
(3) or compared with coarseness Type division：Such as：Whether it is high-rate service；Whether it is real time business；Whether
It is speech business；Whether it is video traffic；Whether it is rate guarantee business；Deng；
(4) or the preferential rate of business (Prioritized Bit Rate, abbreviation PBR) or guaranteed rate
(Guaranteed Bit Rate, abbreviation GBR)；
Message 3 is the general designation of the Article 3 message of random access procedure in LTE system, and similar, message 5 is LTE system
The general designation of 5th article of message of middle random access procedure.
UE and access net establish that RRC connects can be by 3 kinds of RRC processes：Process is established in RRC connections, RRC connections restored
Journey, RRC connection reestablishment procedures；
During this 3 kinds of RRC, UE can give service feature information reporting to access net base in message 3 or message 5
It stands.Such as：During RRC connections are established, what message 3 included is RRC connection request message, and what message 5 included is RRC connections
It establishes and completes message；
In RRC connection recovery processs, what message 3 included is RRC connection recovery request message, and that message 5 includes is RRC
Connection restores to complete message；
In RRC connection reestablishment procedures, what message 3 included is RRC connection reestablishment request message, and that message 5 includes is RRC
Connection reconstruction completes message；
Other than carrying service feature information in RRC information body, service feature information can also be included in MAC by UE
It is reported in CE.
Can step 403. base station service the UE according to the judgement of the service feature information of acquisition, since current UE is using covering
Enhance rank 2 to initiate random access, PRACH repetition factors are up to 32, according to existing eMTC agreements, can prejudge its scheduling
Time delay (including PDCCH reception time and data transmit-receive time) will be no less than 64 times of transmission intercals namely 64ms, the sky of consumption
Mouth resource is by 32 times no less than without coverage enhancement UE, and current system has been in higher load, and servicing the user will likely lead
Access net overload is caused, therefore the RRC connections of the UE cannot be received.
If base station receives the service feature information in message 3, base station sends RRC connection reject message to UE；Institute
Stating refuse information includes：RRC connections establish refuse information, RRC connections recovery refuse information, RRC connection reconstructions refuse information it
One；
If base station receives the service feature information in message 5, base station sends RRC connection release message to UE；
Optionally, base station can refusal either release user equipment RRC connections downstream message in increase refuse or
The reason of release；Reason includes one of the following：
It cannot be satisfied quality of service requirements；
Current coverage enhancement rank mismatch quality of service requirements,
Access net load can not support current coverage enhancement rank；
Access net overload.
Specific embodiment 2：
By taking LTE eMTC systems as an example, the present embodiment describes eMTC access nets and is directed to the reality for having used big coverage enhancement rank
When service terminal RRC connections control, access net from core-network side obtain service feature information；
Unlike specific embodiment 1, in the present embodiment, it is online to access in RRC connection procedures terminal is not needed
Report business characteristic information, but the service feature information of terminal is stored in core net as registration content in advance, when terminal is complete
After the attachment of pairs of network, core network mobility management entity MME (Mobility Management Entity) can be obtained
The service feature information of terminal.When terminal wants that establishing RRC with access net connects, access net can obtain terminal-pair from MME
The service feature information answered, to judge whether that the RRC connections that can receive the terminal are established.
Fig. 5 is the protocol procedures figure of this specific embodiment of the invention 2, and flow is as follows：
Step 501：UE, which is determined, to initiate random access in current area, establish and access the connection of net, UE is according to oneself
Measurement result in current area, using coverage enhancement rank 2, PRACH repetition factors 32 initiate random access.
Step 502：UE sends attach request or service request to MME；The message bearing is in message
In 5, MME is transmitted to by base station
Step 503：The service feature information of the UE is sent to base station by MME in S1 interface messages, and the business is special
Form, the content of reference breath can refer to specific embodiment 1.
Step 504：Can base station eNB service the UE according to the service feature information, judgement, be covered since current UE uses
Lid enhances rank 2 to initiate random access, and PRACH repetition factors are up to 32, according to existing eMTC agreements, can prejudge its tune
64 times of transmission intercals namely 64ms will be no less than by spending time delay (including PDCCH reception time and data transmit-receive time), consumption
Interface-free resources are by 32 times no less than without coverage enhancement UE, and current system has been in higher load, and servicing the user will likely
Lead to access net overload, therefore the RRC connections of the UE cannot be received.
Step 505：Base station sends RRC connection release message to UE；
