Description
Technical field
The present invention relates to the communications field, in particular to a kind of Radio Resource control method and device.
Background technology
3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution; Abbreviation LTE) system is by universal land radio access web (the Evolved Universal Terrestrial Radio Access Network of evolution; Abbreviation E-UTRAN), subscriber equipment (User Equipment; Abbreviation UE), the packet-based core networks of evolution (Evolved Packet Core is called for short EPC) are formed.Wherein, E-UTRAN is made up of the enhanced base station (eNB) of access network elements.ENB is connected with terminal UE through the Uu interface, through S1 interface and core network element, connects like Mobility Management Entity (Mobility Management Entity is called for short MME).
At present, situation such as overload can not take place for the multi-level access control treatment mechanism of having access to of subscriber equipment because excessive subscriber equipment inserts to guarantee network side in network side.
Subscriber equipment access network side need be accomplished plurality of processes as shown in Figure 1, and in this example, the network side access device is made as Mobility Management Entity MME:
Step 102, random access procedure: subscriber equipment is synchronous through this process completion and network side;
Step 104, RRC (Radio Resource Control, Radio Resource control) connect and set up process: the signaling bear of setting up subscriber equipment and access network elements;
Step 106, adhere to (Attach) process: accomplish the obtaining of customer equipment identification information, authentication process and safety and set up (Security Setup).
In existing protocol, network side inserts rank (Access Class is called for short AC) for the different call type is provided with 15, and wherein common calling all belongs to AC0～9, and urgent call belongs to AC10, and the calling of other high priorities belongs to AC11～15.Network side is that AC0～9 are provided with controlling elements, for AC10 and AC11～15 are provided with the sign of " whether forbidding ", and is broadcast to subscriber equipment, to control the behavior of access at random of these type of calls.
Set up in the process in the RRC connection, the Signalling exchange of subscriber equipment and access network elements such as Fig. 2, Fig. 3 and shown in Figure 4 have to connect and set up, connect refusal and be connected three kinds of flow processs of release, and in the sketch map of Fig. 2, Fig. 3 and Fig. 4, the network side access device is the base station.
As shown in Figure 2, connect foundation and comprise following flow process:
Step 202, subscriber equipment are initiated RRC connection foundation and are asked for instructions;
Step 204, base station connect to subscriber equipment feedback RRC sets up message;
Step 206, subscriber equipment send the RRC connection setup complete message to the base station.
As shown in Figure 3, connect refusal and comprise following flow process:
Step 302, subscriber equipment are initiated RRC connection foundation and are asked for instructions;
Step 304, base station are to subscriber equipment feedback RRC connection refused message.
As shown in Figure 4, connect release and comprise following flow process:
The RRC connection release message is sent to subscriber equipment in step 402, base station.
Network side is through these 3 flow processs, just can be, and information such as air interface load capacity according to data payload ability and the signaling load ability of self, the RRC of subscriber equipment is connected the judgement that foundation asks to make " acceptance ", " refusal " and " release ".
Consider that the connection request that subscriber equipment is initiated possibly be based on different types of business; And professional priority possibly be different; Therefore in order to realize admitting more efficiently more flexibly control; In present rrc layer agreement, require subscriber equipment to connect to carry in the request of setting up (RRC Connection Request) and connect the cause information of setting up at RRC.
Existing connection is set up cause information (establishment Cause) and is comprised following content:
Emergency (urgent, what the subscriber equipment initiation was described is urgent call);
High Priority Access (height preferentially inserts, and what the subscriber equipment initiation was described is that high preferential service class is called out);
Mt-Access (explaining that subscriber equipment is owing to called the application connects);
Mo-Signalling (explaining that subscriber equipment is to initiate caller signaling class to call out);
Mo-Data (explaining that subscriber equipment is to initiate the caller data class to call out).
Need to prove that the subscriber equipment that cause information is only applicable to 3GPP release 9 and former version is set up in above-mentioned connection.
Because at present RRC connects that to set up request message be in the message of random access procedure 3 message, to carry, and the size of message 3 message is limited, so RRC connects to set up in the request message and can't increase more new information again.
Along with the Internet of Things conception development, entire society will be progressively introduced in the communication (in 3GPP, being referred to as the Machine Type communication, i.e. MTC) of M2M (Machine to Machine, machine to machine).The sense stricto definition of M2M is the communication of machine to machine, and sensu lato definition is the application and the service of core, networking with the machine terminal intelligent interaction.It is the access means based on the intelligence machine terminal with multiple communication mode, is the informatization resolve scheme that the client provides, and is used to satisfy the information system requirement of client to aspects such as monitoring, command scheduling, data acquisition and measurements.
In the application of M2M; Type of service is very extensive; For example family checks meter, commercial production instrument automation, monitoring water quality, intelligent transportation and assets are followed the trail of or the like, and the application of M2M will get into all trades and professions, huge numbers of families, and the type of service of M2M also will be thousands of; To network side with the QoS (service quality, Quality of Service) of operator is required also will be diversified.The quantity of the subscriber equipment of M2M also will be considerably beyond present mobile phone terminal, and this has just constituted the immense pressure of business load to the current and even following wireless network.Because M2M subscriber equipment quantity is huge, therefore 3Gpp has proposed the notion of subscriber equipment being managed according to (Group) mode of grouping at present.
Under the M2M application background, how how protecting network prevents that overload from appearring in network, become a problem of primary solution at present.
In the current agreement; Subscriber equipment can connect with network inserting at random; And accomplish in the process of adhering to; Access network elements can carry out access control to random access procedure, also can connect the request of foundation to the RRC of subscriber equipment at rrc layer and control, but the flexibility ratio of present controlling mechanism can not satisfy the admittance of high density, multiple services subscriber equipment has been controlled.
For example: the statistical result showed of present operator, the load of the data service in the radio communication (for example online, video call, FTP (File Transfer Protocol, FTP) download etc.) has surpassed the load of speech business.When the network faces overload pressure; Proper way is that the data business is carried out certain admittance restriction, and guarantees the normal service of speech business, because usually from operator's angle; Speech business is the basis of network operation; But according to present consensus standard, when subscriber equipment was initiated audio call and data service calls, it all was same data model mo-Data that cause information is set up in the connection in RRC connection foundation request; Network side can't be distinguished voice or data service, therefore can't admit control flexibly.
In addition; The application of different M2M has the different service model; Data transfer model when business model is meant subscriber equipment and network side interaction data, the key element of statement business model comprises: data interaction periodicity, data interaction frequency, size of data, data interaction direction (refer to the upstream data be main or with the downlink data be lead or the up-downgoing flow close).With the intelligent electric meter is example; The Utilities Electric Co. that has requires every intelligent electric meter to report one time meter reading data in per 5 minutes; The Utilities Electric Co. that has requires every intelligent electric meter to report one time meter reading data in per 1 hour; The Utilities Electric Co. that has even only require that intelligent electric meter reports one time meter reading data every day; The flow of each meter reading data is less, and this has just constituted 3 kinds of different service models, and periodically small data reports, low-frequency degree periodicity small data reports, extremely low frequency degree periodicity small data reports can be called frequent respectively.For example common again speech business can be described as periodically small data interaction models of high frequency.Business of networking (common tens seconds click a webpage, be main with downlink data, and data traffic is bigger) for example again, the big data down transmission model of frequency aperiodicity in can be described as.These different service models are different for the pressure of network clearly, and present mechanism is to distinguish these professional models.
Different service also has different Qos requirements; The Qos more relevant with admitting control ratio requires to comprise: the tolerance of access delay; The service interfacing that for example has goes into to postpone very responsive (business such as for example fire alarm, security protection, medical monitoring); The service interfacing that has is gone into delay-sensitive degree lower (for example checking meter), and present mechanism is to distinguish these differences.
Different service or subscriber equipment also have different priority, and for example the priority with finance, security protection, business that medical treatment is relevant should be higher than common business, and present mechanism can't be distinguished.
Above-mentioned defective is after the M2M extensive use, and it is more serious to become.
Flexibility ratio to controlling mechanism present in the correlation technique can not satisfy the problem to the admittance control of high density, multiple services subscriber equipment, does not propose effective solution at present as yet.
