Description
Technical field
The present invention relates to wireless communication field, the control method, terminal and the system that insert in particular to a kind of terminal.
Background technology
In prior protocols, control for access behavior subscriber equipment, introduced access control mechanism in the agreement.This mechanism has been stipulated 16 access grades (AC, Access Class) altogether, and wherein, AC 0～9 is corresponding to ordinary call, and AC 10 is corresponding to urgent call, and AC 11～15 is corresponding to other special calling.For AC 0～9, network side is the corresponding access control factor (Barring Factor) for each AC has set, and for AC 10～15, and network side has been set the sign of a 1bit for each AC, and is broadcast to the terminal through system message.When inserting corresponding to the terminal of a certain AC, if the AC at this terminal belongs to 0～9, then the terminal can produce the random number between 0～1; If this random number is less than the pairing controlling elements of AC; Then this terminal can be inserted, otherwise this terminal is postponing to reattempt access after a period of time; If the AC at this terminal belongs to 11～15, then if the corresponding bit of AC is 0, then this terminal can be inserted, otherwise this terminal is postponing to reattempt access after a period of time; If the AC at this terminal is 10, then if the corresponding bit of AC is 0, then this terminal can be inserted, otherwise this terminal attempts inserting at once once more.This mechanism can effectively be tackled possibly occur in the existing network congested, prevents that the situation of overload from appearring in network.
But, along with the development of technology, the Internet of Things notion has appearred; The Internet of Things notion of narrow sense is meant communicating by letter between machine and the machine, and (Machine to Machine is called for short M2M, at 3GPP (3rd Generation Partnership Project; Third generation partner program) in the meeting; M2M again by project verification for " Machine Type Communication ", be called for short MTC), the Internet of Things notion of broad sense is except comprising communicating by letter between machine and the machine; Also comprise traditional interpersonal communication (Human to Human is called for short H2H).
After introducing the Internet of Things notion, communication service is expanded the every aspect of all trades and professions.For example Smart Home (Long-distance Control that comprises household appliances, remote monitoring of family's security protection or the like), intelligent transportation (monitoring of the magnitude of traffic flow, accident monitoring, vehicle monitoring etc.), intelligent metering (monitoring of industrial instrument and Long-distance Control, remote meter reading etc.) etc.Therefore, the quantity at M2M terminal will be considerably beyond the H2H terminal.Simultaneously, less different usually with the call arrival density at H2H terminal, the call arrival density at M2M terminal is very big usually.So after having introduced the Internet of Things notion, the main cause that causes network congestion no longer is the access at H2H terminal, but the access at a large amount of M2M terminals.
In addition, after introducing the Internet of Things notion, the type at terminal no longer has only the H2H terminal, but also comprises the M2M terminal, and existing access control mechanism can not effectively be distinguished these two kinds of terminals.
And; Different M2M uses possibly have the different service model; Data transfer model when business model is meant subscriber equipment and network side interaction data, the key element of expression 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.Clearly these different service models are different for the pressure of network, and present mechanism can't be distinguished these business models.
In addition; Different service also possibly have different service quality (QoS; Quality ofService) requirement, the qos requirement relevant with access control comprises: 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 can't distinguish that these are different.
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 also can't be distinguished.
So after M2M communication extensive use,, can not effectively tackle or avoid network congestion, thereby can seriously influence network communication quality because existing access control mechanism can not carry out the access control operation neatly according to inserting object type.
Summary of the invention
Main purpose of the present invention is to provide control method, terminal and the system of a kind of terminal access, causes network congestion to solve above-mentioned because existing access control mechanism can not successfully manage or avoid the M2M terminal to insert in a large number, thereby influences the problem of communication quality.

Embodiment 2
The control method that present embodiment provides a kind of terminal to insert describes in LTE (Long-Term Evolution, Long Term Evolution) system, to be embodied as example.The access control operation need be carried out in the terminal before initiating to insert at random, as shown in Figure 3, and the main step of this method is following:
Step S300, network side sends the access control object type to the terminal, and access control object type corresponding access control information.
Wherein, network side can send above-mentioned information through system message or beep-page message, that is, access control object type, and access control object type corresponding access control information, this moment, the terminal obtained above-mentioned information through monitoring system message or beep-page message.Step S302; The terminal receives the access control object type from network side, and access control object type corresponding access control information, according to the access control object type under self; And access control object type corresponding access control information according to the network side transmission; Obtain this terminal corresponding access control information, wherein, access control information comprises the access control factor (ac-BarringFactor) and access control time delay (ac-BarringTime); Perhaps flag bit, designator, for example bit.
Step S304, the access control operation is carried out according to access control information in the terminal, concrete control as follows:
Access control information is flag bit or designator, for example bit: if this bit is " 0 ", represent that then the terminal can initiate to insert at random; If this bit is " 1 ", represent that then the terminal can not initiate to insert at random.
Access control information is the access control factor (ac-BarringFactor) and access control time delay (ac-BarringTime): the terminal produces a random number; And with this random number and the comparison of the access control factor; If random number is less than the access control factor; Represent that then the terminal can initiate to insert at random, otherwise, represent that then the terminal can not initiate to insert at random.
If the terminal can not initiate to insert at random, the terminal produces delay time according to the access control time delay, after this delay time reaches; Access control is carried out at this terminal once more; For example, the terminal produces a random number (rand), and according to formula: (0.7+0.6*rand) * ac-BarringTime produces time of delay; After this time of delay, carry out the access control operation again.
" type of access control object " in the present embodiment is meant a kind of or multiple combination in the following information: terminal type information, terminal PRI information, end packet (group) information, terminal PLMN information, service priority information, QoS of survice information or business model information.
Terminal type information comprises following one or more: H2H terminal, M2M terminal, other types terminal.
Terminal PRI information is meant in advance and appoints with network side that perhaps the priority at signatory terminal comprises: priority sequence number, perhaps priority tag.Existing H2H terminal can be used as a priority; Except that this priority, can also set up one or more priority, these priority of setting up can be higher or lower than existing H2H terminal PRI; With existing H2H terminal is basic priority, can classify as follows:
1) set up a priority, comprise following two kinds of forms:
The H2H terminal, low priority terminal (with respect to the H2H terminal);
Perhaps, high priority terminal (with respect to the H2H terminal), H2H terminal.
2) set up a plurality of priority, comprise following three kinds of forms:
The A:H2H terminal, 1 grade of terminal of low priority, 2 grades of terminals of low priority ..., low priority N level terminal (N is a positive integer);
B: the highest priority of 1 level terminal, 2 grades of terminals of high priority ..., high priority M level terminal (M is a positive integer), H2H terminal;
C: the highest priority of 1 level terminal, 2 grades of terminals of high priority ..., high priority M level terminal, the H2H terminal, 1 grade of terminal of low priority, 2 grades of terminals of low priority ..., low priority N level terminal (M, N are positive integer);
For example, network side and M2M terminal agreement, the priority at M2M terminal is lower than the H2H terminal, then one has two kinds of priority endpoint in the network: H2H terminal, M2M terminal.
The grouping information at terminal is meant the sign of end packet (Group), comprising: the sequence number of end packet (Group) or sign.For example; The grouping information at terminal can directly be used Group-RNTI (Radio Network Temporary Identifier; Radio Network Temporary Identifier), also can use a sequence number of making an appointment with network side, network side is set up the one-to-one relationship of this sequence number and grouping in advance.

Service priority information is meant in advance and network side is appointed, perhaps the priority of signatory business comprises: priority sequence number, perhaps priority tag.In existing protocol, the type of service that access control comprises has Emergency (terminal initiate be urgent call), MO-Signalling (terminal is initiatively initiated the signaling class and called out) and MO-Data (the data class calling is initiatively initiated at the terminal).In addition, present embodiment can also be introduced new service priority (following " H2H is professional " refers to already contained type of service in the existing protocol), for example:
1) set up a priority, comprise following two kinds of forms:
H2H is professional, low priority traffice (professional with respect to H2H);
Perhaps, high-priority service (with respect to the H2H terminal), H2H is professional.
2) set up a plurality of priority, comprise following three kinds of forms:
A:H2H is professional, 1 grade of business of low priority, and 2 grades of business of low priority ..., low priority N level professional (N is a positive integer);
B: the highest priority of 1 level is professional, 2 grades of business of high priority ..., high priority M level professional (M is a positive integer), H2H is professional;
C: the highest priority of 1 level is professional, 2 grades of business of high priority ..., high priority M level is professional, and H2H is professional, 1 grade of business of low priority, 2 grades of business of low priority ..., low priority N level professional (M, N are positive integer);
For example, for ammeter class MTC (Machine Type Communication, Machine Type communication) business, it mainly acts on is to report the ammeter parameter, and service priority is lower; Type MTC is professional for the finance data transmission, and it mainly acts on is to transmit finance data constantly, and service priority wants high than the ammeter class is professional; Type MTC is professional for alarm, and its effect is to alarm, and service priority is higher.So the priority of these three types of business is arranged as follows from high to low: alarm type MTC professional (high-priority service), finance data transmission type MTC professional (H2H is professional), ammeter class MTC professional (low priority traffice).
QoS of survice information comprises one or more combination of following requirement: the tolerance of access delay, the flow of assurance, the error rate of allowing.For example: with the access delay is example, can be set to:
Two-stage: to inserting delay-sensitive, insensitive to access delay;
Multistage: the access delay susceptibility is high, in the access delay susceptibility, the access delay susceptibility is low;
Also can be the combination of multiple qos requirement, for example: access delay susceptibility height+low guaranteed flow+low error rate requirement; Perhaps, in the access delay susceptibility+high dependable flow+low error rate requirement; This QoS also can be divided into thinner progression.
The business model information of present embodiment is meant professional data communication model, comprises one or more following combination of features: data interaction periodically (whether being that periodic data is mutual), data interaction frequency, data volume size, data interaction direction (refer to the upstream data be main be main with the downlink data or the up-downgoing flow close).For example:
Include only a kind of information of characteristic: small data business model or frequent business model or periodic traffic model;
Comprise manifold information: periodically small data business model, low-frequency degree periodically small data report, the extremely low frequency degree periodically small data report, high frequency periodically small data interaction models, the big data down transmission model of middle frequency aperiodicity etc.
Concrete type of service and the corresponding relation between the business model are made an appointment by network side and subscriber equipment or are signatory.
Above-mentioned access control object type can have various ways, and promptly the type of access control object can be one or more of above type, or multiple merging.For example:, as shown in table 1 with the PLMN information combination of terminal PRI information (is example with two priority) with the terminal:
