Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method of access control, system and equipment.
Background technology
For subscriber equipment (UE), each subscriber equipment all can have an AC (Access Class, access grade), and AC is the number in (0...9).AC can be kept in the SIM/USIM card of subscriber equipment.In addition, some subscriber equipment also possibly have special AC (11...15).Subscriber equipment with special AC has higher priority in some applications.
Present UMTS (Universal Mobile TelecommunicationSystem; Universal mobile telecommunications system) and LTE (Long Term Evolution; Long Term Evolution) the access control scheme is based on all that the AC of subscriber equipment forms in the system; Be referred to as ACB (Access Class Barrinig, access grade is forbidden) mechanism.For UMTS and LTE system, the concrete operations of ACB are again different.
For UMTS, ACB mechanism is whether all can provide this AC by the barred indication of (forbidding) to each AC (0...15).The ACB parameter of UMTS is included among the SIB (System Information Block, system information block) 3, and when network monitor need forbid maybe that to generation is congested certain user's equipment inserts, network side can be broadcasted ACB in SIB3; When reading, subscriber equipment carries the ACB parameter among the SIB3; Before initiating access at random; Can be kept at SIM (Subscriber Identity Module according to content and the subscriber equipment of ACB among the SIB3; User identification module)/ AC in USIM (Universal Subscriber Identity Module, the universal subscriber identity module) card judges whether to be allowed to insert by network.
For the LTE system; What AC was that the subscriber equipment of 0...9 uses is identical access probability; Promptly forbid the factor (ac-BarringFactor)+the forbid mode of duration (ac-BarringTime), what be that the subscriber equipment of 11...15 uses for AC is the mode of bitmap (bit map).The ACB parameter of LTE system is included among the SIB2, and when network monitor need forbid maybe that to generation is congested certain user's equipment inserts, network side can be broadcasted ACB in SIB2; When reading, subscriber equipment carries the ACB parameter among the SIB2; The subscriber equipment that for AC is 0...9 is before initiating to insert at random; At first generate a random number ' rand ' (0≤rand＜1); If ' rand '＜ac-BarringFactor; Then subscriber equipment can initiate to insert; Otherwise start timer " Tbarring "=(0.7+0.6*rand) * ac-BarringTime, in the timer scope, the rrc layer of subscriber equipment can not initiate to insert at random again.For AC is the subscriber equipment of 11...15; When peculiar one corresponding of the ratio of forbidding in (ac-Barring For Special AC) parameter of special AC is changed to 0; Just can directly initiate to insert; Otherwise; Subscriber equipment can generate a random number ' rand ' (0≤rand＜1); If ' rand '＜ac-BarringFactor; Then subscriber equipment can initiate to insert; Otherwise start timer " Tbarring "=(0.7+0.6*rand) * ac-BarringTime; In the timer scope, the rrc layer of subscriber equipment can not initiate to insert at random again.
M2M (Machine to Machine; Machine) communication technology causes people's attention gradually; 3GPP (3rd Generation Partnership Project; 3G (Third Generation) Moblie standardization body) standardization body also sets up the project the M2M technology is specialized in; Therefore, all need support MTC communication for UMTS and LTE system.
M2M communication is different from existing H2H (Human to Human; The Human To Human) subscriber equipment; The M2M subscriber equipment has some characteristics; Such as; M2M subscriber equipment quantity is far away more than present H2H subscriber equipment; The communication of M2M subscriber equipment has time delay tolerance characteristic, and the M2M subscriber equipment it is generally acknowledged to have lower priority etc.Many just because of M2M subscriber equipment quantity, so in some scene, for example the M2M subscriber equipment sends data simultaneously or has a power failure and powers on afterwards again, causes Access Network congested more easily.To this situation, standard proposes to use the mode of EAB (Extended Access Barring, the access control of expansion) to solve this problem at present.EAB thinks to have characteristic similar with ACB and method for using based on the expansion on the current ACB basis.
When network congestion takes place; The possible a kind of implementation method of network is to adjust ACB list (UMTS) or ac-BarringFactor/ac-BarringTime (LTE system) dynamically with better saving random access resource according to current congestion condition, reduces the access delay of subscriber equipment.Especially, for the ACB of UMTS mechanism, network side maybe be through changing by the AC of barred dynamically, and the subscriber equipment of avoiding some AC occurring is always by barred, and cause inserting the generation of phenomenon.These implementation methods can embody better fairness.Especially insert simultaneously in the congested scene of the access that causes for a large amount of M2M subscriber equipmenies, possibly need more frequent change EAB parameter just can reach comparatively ideal effect.
But in the present technology, can only realize that through the renewal of system message network side changes the ACB parameter dynamically.The frequent variations of system message needs the frequent read system message of subscriber equipment, causes power consumption.For only being suitable for a certain kind equipment; In the EAB mechanism like MTC equipment; If system message frequent variations; Because system message is a cell-level, all subscriber equipmenies of sub-district are that M2M type of user equipment or H2H subscriber equipment all need remove read system message; In case system message alteration; Even the content of these system messages is that the H2H subscriber equipment also will go to read, so also can have influence on the H2H subscriber equipment to the subscriber equipment of M2M type.
In sum, can only realize that network side changes the ACB parameter dynamically, thereby cause the system message frequent variations through the renewal of system message at present.

Embodiment
To can only be in the background technology through the renewal of system message; Realize that network side changes the ACB parameter dynamically; Thereby cause the problem of system message frequent variations; Embodiment of the invention subscriber equipment is confirming not allow to initiate RRC (Radio Resource Control; Radio Resource control) after request is set up in connection, adjustment access control parameter.Regulate access control parameter (being the ACB parameter) owing to realized the subscriber equipment self adaptation, thereby reduced the access delay at terminal, reduce the change of the message of system, improve network resource usage efficient.
Preferably, the parameter that the network of the embodiment of the invention is correlated with through the system information broadcast access control, the access control relevant parameter in the subscriber equipment saved system information, and the own employed ACB parameter of the adjustment of rule by appointment.Network needn't be frequent again dynamic change ACB parameter.Wherein, above-mentioned access control relevant parameter can be the ACB parameter that has defined in the present standard, and the needs of rule according to a preconcerted arrangement that can also be extra comprise more heterogeneous related parameter.
Shown in Figure 1A, the method for the parameter that network side broadcasting access control is relevant comprises:
Step 101, network side monitor RAN (Radio Access Network, wireless access network) and overload, the relevant parameter of broadcasting access control;
Step 102, subscriber equipment are received and are preserved the relevant parameter of receiving of access control;
Step 103, initiate RRC when the NAS of subscriber equipment layer request rrc layer and connect when setting up request, use the relevant parameter of access control of having preserved to begin the access control flow process.
Wherein, the embodiment of the invention can be applied among LTE system or the UTMS, can also be applied in other systems that need adjust the access control parameter.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
In the declarative procedure below; Implement to describe from the cooperation of network side and user equipment side earlier; Describe from the enforcement of network side and user equipment side respectively at last; But this does not also mean that the two must cooperate enforcement; In fact, separate when implementing, also solved respectively in network side, the existing problem of user equipment side when network side and user equipment side; When just the two is used in combination, can obtain better technique effect.
Shown in Figure 1B, embodiment of the invention system of access control comprises: network equipment 10 and subscriber equipment 20.
Such as, subscriber equipment 20 judges whether that according to initial access control parameter allowing to initiate RRC connects the request of foundation for the first time, if allow, confirms that then the access control parameter allows to initiate RRC and connects the request of foundation (if having other restriction also need continue to judge); Otherwise initial access control parameter; And then judge whether allow to initiate RRC according to adjusted access control parameter and connect the request of foundation, if allow then confirm that the access control parameter allows to initiate RRC and connects the request of foundation (if having other restriction also need continue to judge); Otherwise continue adjustment access control parameter, and the like.
Preferably, subscriber equipment 20 is according to one or more adjustment access control parameters in the following rule:
Rule 1, periodic poll insert forbidden AC in the Control Parameter;
Rule 2, every certain interval of time reduce or increase the AC number that is under an embargo and inserts;
Rule 3, every certain interval of time increase or reduce access barred parameter value (promptly inserting the factor) based on certain step value;
Rule 4, every certain interval of time increase or reduce access barred length of timer (in the timer scope, the rrc layer of subscriber equipment can not initiate to insert at random again) based on certain step value;
Rule 5, the effective duration of access control parameter is set.
Accordingly, the adjustment parameter that network equipment 10 sends is used for adjusting the access control parameter includes but not limited at least a of following parameters:
The initial step value of the initial cycle of adjustment access control parameter, adjustment access control parameter and initial step value adjustment are at interval.
For rule 1; Such as network equipment 10 at SIB (System Information Broadcast; System information broadcast) broadcasting ACB parameter is ACB list in 3, and wherein the terminal of AC 1-9 all is under an embargo, and only allowing AC is that 0 subscriber equipment is initiated RRC and is linked into network.After through after a while (such as the interval=25*SIB cycle), subscriber equipment thinks that present ACB list is AC 0, and the subscriber equipment of 2-9 all is under an embargo, and only allowing AC is that 1 subscriber equipment is initiated RRC and is linked into network.By that analogy, every separated interval cycle of terminal is so long with regard to conversion ACB list.Embody the fair frequent change system message of network of avoiding simultaneously so more.
In force, the cycle is that agreement is stipulated or subscriber equipment is definite or is disposed by network side.
If subscriber equipment 20 oneself is confirmed the cycle, preferably subscriber equipment 20 is confirmed the cycle according to the initial access control parameter of network side configuration.Allowing to insert the AC number such as configuration in the initial access parameter is n, and the cycle can be n*T so, and wherein T is basic chronomere, can be the value of agreement regulation.That is to say that the cycle is the relation of multiple with allowing the access grade number.
In the above example; Interval can but be not limited to relevant with SFN; Interval=50 for example; Other AC outside the AC0 are by barred; Then this terminal of current time confirms that according to (SFN mod (50*10))/50+ACnotbarred which AC can insert; If a plurality of AC are not by barred among the ACB list, then use respectively and bring top formula for AC number into and calculate, draw the AC list that certainly inserts.Interval also can be that each subscriber equipment 20 directly added up according to the time of own initiation request, uses the mode of similar timer, and the time that crosses Interval is just carried out the mode of cyclic shift to the AC that allows to insert.The advice method of Interval can but to be not limited to be network through RRC signaling static configuration such as broadcasting, also can be the agreement agreement.
For rule 2; Such as initial access control parameter is the access that all is under an embargo of the subscriber equipment of AC 0-9; Crossed so after the certain hour interval T, subscriber equipment thinks that the subscriber equipment that present access control parameter becomes AC0-5 is under an embargo, and the subscriber equipment of AC6-9 is allowed to access.If the AC grade of this subscriber equipment is among the 6-9 so, pass through the duration of T so after, subscriber equipment is thought own and is allowed to insert by network.Forbidden in other words AC grade has reduced gradually.
For rule 3, subscriber equipment 20 is with Fixed Time Interval, and the fixed step size value increases or reduce the access barred parameter value.
Such as: network equipment 10 is broadcasted the ACB parameter in SIB2 be 0.2 for the access barred parameter value, and timer is 4s.Subscriber equipment 20 begins to initiate to insert at random this parameter of use; After being under an embargo, through after the interval=15s, subscriber equipment 20 thinks that the ACB parameter becomes 0.2+0.1, and timer is 4s.If also be under an embargo, through after the interval=15s, subscriber equipment 20 thinks that the ACB parameter becomes 0.2+0.1+0.1, and timer is 4s; By that analogy, subscriber equipment 20 can improve the access barred parameter value gradually, is allowed to probability to improve to insert.Wherein each step-length (present embodiment is 0.1) that improves can but to be not limited to be that network side passes through broadcasting and waits RRC signaling static configuration, obtains through modes such as (with to insert this parameter of use etc. relevant) calculating of agreement agreement computing formula or agreement agreements.
For rule 3; Subscriber equipment 20 can also increase or reduce the access barred parameter value with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back interval greater than or less than the previous time interval, and corresponding step value of back time interval is greater than or less than corresponding step value of the previous time interval.
Here comprise possibility in 4:
1, increases or reduces the access barred parameter value with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back is interval greater than the previous time interval, and corresponding step value of back time interval is greater than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to increase gradually, the step value that raises increases or reduces access access barred parameter value gradually;
2, increase or reduce the access barred parameter value with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back is interval greater than the previous time interval, and corresponding step value of back time interval is less than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to increase gradually, the step value that reduces increases or reduces access access barred parameter value gradually;
3, increase or reduce the access barred parameter value with the corresponding step value of current time interval; In wherein any adjacent two time intervals; Time interval of back is less than the previous time interval, and the step value of back time interval correspondence is greater than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to reduce gradually, the step value that raises increases or reduces access access barred parameter value gradually;
4, increase or reduce the access barred parameter value with the corresponding step value of current time interval; In wherein any adjacent two time intervals; Time interval of back is less than the previous time interval, and the step value of back time interval correspondence is less than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to reduce gradually, the step value that reduces increases or reduces access access barred parameter value gradually.
With 3 be example such as, for the first time through 5s, increase by 0.1; Pass through 4s next time, increase by 0.2; Pass through 3s more next time, increase by 0.3, and the like.
For rule 3, preferably, if be applied in the LTE system, the access barred parameter value is ac-BarringFactor; If be applied in UMTS, the access barred parameter value is persistent value.
For rule 4, subscriber equipment is with Fixed Time Interval, and the fixed step size value increases or reduce the access barred length of timer.
Such as: in the initial access parameter, forbid that the length of duration is 16s, that is to say subscriber equipment 20 access that in a single day is under an embargo, no longer be allowed to access in the 16s at least; Crossed after the certain hour interval T, subscriber equipment 20 thinks that the present duration of forbidding has become 8s, and after the terminal was under an embargo intervention once more, the duration that is not allowed to initiate to insert had just shortened to 8s.
For rule 4; Subscriber equipment 20 can also increase or reduce the access barred length of timer with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back interval greater than or less than the previous time interval, and corresponding step value of back time interval is greater than or less than corresponding step value of the previous time interval.
Here comprise possibility in 4:
1, increases or reduces the access barred length of timer with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back is interval greater than the previous time interval, and corresponding step value of back time interval is greater than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to increase gradually, the step value that raises increases or reduces the access barred length of timer gradually;
2, increase or reduce the access barred length of timer with the corresponding step value of current time interval; In wherein any adjacent two time intervals; One of back is interval greater than the previous time interval, and corresponding step value of back time interval is less than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to increase gradually, the step value that reduces increases or reduces access access barred length of timer gradually;
3, increase or reduce the access barred length of timer with the corresponding step value of current time interval; In wherein any adjacent two time intervals; Time interval of back is less than the previous time interval, and the step value of back time interval correspondence is greater than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to reduce gradually, the step value that raises increases or reduces access access barred length of timer gradually;
4, increase or reduce the access barred length of timer with the corresponding step value of current time interval; In wherein any adjacent two time intervals; Time interval of back is less than the previous time interval, and the step value of back time interval correspondence is less than corresponding step value of the previous time interval.Be the time interval of subscriber equipment to reduce gradually, the step value that reduces increases or reduces access access barred length of timer gradually.
With 3 be example such as, for the first time through 5s, increase by 0.1; Pass through 4s next time, increase by 0.2; Pass through 3s more next time, increase by 0.3, and the like.
