Embodiment
3-G (Generation Three mobile communication system) with and long evolving system in; Need to support the MTC communication function, wherein, core net need be handled conventional wireless terminals (like the H2H terminal; Subscriber equipment) communication and MTC devices communicating; Because the MTC number of devices can be a lot, can be under some special screne because MTC communication cause the relevant treatment unit generation signaling congestion of core net, and core net can be directed against MTC equipment to time delay insensitive or its be in characteristics such as roaming state; Limit through of the access of signaling Access Network, alleviate or eliminate the congested state of core network signalling thereby reach to the MTC equipment that possesses certain characteristic.
In the LTE system, can insert restriction to reach the purpose of control MME signaling congestion to specific conventional wireless terminals through S1 interface (interface of core net MME and eNB) signaling procedure (like OVERLOAD START (load begins) and OVERLOAD STOP (load end) process).Wherein, OVERLOAD START process is used for MME notice eNB refusal and initiates to insert former because the RRC of the UE of specific reasons (Radio Resource Control, Radio Resource control) connects the request of foundation, thereby reduces the signaling traffic load of MME.
When eNB receives OVERLOAD START message; Think that MME is in congestion state; Then according to the indicated information of Overload Action (action) information unit of carrying in the OVERLOAD START message; Refusal RRC sets up former in non-emergent caller data (mo-data) access, or refusal RRC sets up former because the UE of caller data (mo-data) and caller signaling (mo-signalling) inserts or only allow RRC to set up the UE access that reason is urgent call (emergency session) access and called service (mobile terminated services).
Need to prove; According to above-mentioned mode classification, there is the relation that comprises mutually in several types of confined terminal scopes, do not exist the terminal more than 1 type that needs definition simultaneously to insert confined situation; Therefore; Current Overload Action information unit type adopts enumeration type, promptly is merely able to specify a certain Terminal Type access style in the classification to be limited, the structure of Overload Action information unit as shown in table 1 at every turn.
Table 1
When the congestion state of MME is alleviated or is eliminated, then no longer need Access Network (RAN) equipment that the access of UE is limited, at this moment, can pass through OVERLOAD STOP message informing eNB, eNB can recover normal access control to be handled.
In the UMTS system; Can pass through Iu interface (core net SGSN (Serving GPRS Supporting Node; Serving GPRS Support Node) with the interface of RNC (Radio Network Controller, radio network controller)) the OVERLOAD process conventional wireless terminals is inserted restriction to reach the purpose of control core net node (as: SGSN) signaling congestion.Different with the OVERLOAD START process of LTE system is; Access Network stops congested control operation voluntarily through timer and the control information of setting in this OVERLOAD message; Need not through explicit the stopping of OVERLOAD STOP process; Do not specify the UE access style that needs restriction in the OVERLOAD message of UMTS, the structure of Overload information unit as shown in table 2.
Table 2
In the practical application, because the introducing of MTC equipment needs to introduce the access control mechanism to MTC equipment, and can guarantee should mechanism and the collaborative work of existing conventional wireless terminals congestion control mechanism.To supporting in the prior art to the congestion notification of MTC communication and the problem of controlling mechanism; The embodiment of the invention provides a kind of congestion control method and equipment; Carry out congested control to be directed against MTC equipment, and can guarantee this congestion control mechanism and the collaborative work of existing conventional wireless terminals congestion control mechanism.
To combine the accompanying drawing among the present invention below, the technical scheme among the present invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
In order to solve the demand of the new core network congestion control of introducing in the MTC communication, the embodiment of the invention one provides a kind of jamming control method, and is as shown in Figure 1, and this method may further comprise the steps:
Wherein, in the LTE system, equipment of the core network includes but not limited to MME, and interface signaling includes but not limited to the S1 interface signaling, and access network equipment includes but not limited to eNB, other access devices such as trunking (Relay), household base station device (HeNB) etc.; In the UMTS system, equipment of the core network includes but not limited to SGSN, and interface signaling includes but not limited to the Iu interface signaling, and access network equipment includes but not limited to RNC, other access devices such as trunking (Relay), household base station device (HNB) etc.Therefore, in the LTE system, MME limits the access of preset kind UE through S1 interfac message notification eNB; Perhaps, in the UMTS system, SGSN limits the access of preset kind UE through Iu interfac message notification RNC.
In the embodiment of the invention, confirmed the information of preset kind UE when equipment of the core network after, then can carry out this step.Wherein, this preset kind UE is the UE that possesses certain characteristic, includes but not limited to: the MTC equipment of the professional UE of all MTC equipment, all initiation low priorities (Low Priory), roaming, Hypomobility UE, turn-on time controlled UE, the UE of group etc.
When MME notice eNB limits the access of preset kind UE; This MME can add first information unit in the OVERLOAD of S1 interface START message or redetermination S1 message, and through this first information unit notice eNB the access of preset kind UE is limited.When SGSN notice RNC limits the access of preset kind UE; This SGSN can add second information unit in the OVERLOAD of Iu interface message or redetermination Iu message, and through this second information unit notice RNC the access of preset kind UE is limited.
The definition mode that it should be noted that above-mentioned information unit (first information unit and/or second information unit) includes but not limited to: the implication that each bit of definition BIT STRING type (being called bitmap again, the bit map type) and information unit is represented; And/or, the implication that each enumerated value of definition enumeration type and information unit is represented.
Concrete; In the process of definition BIT STRING type and/or enumeration type; Corresponding information unit can be one or more; The information unit of one or more BIT STRING types promptly can be set, the information unit of one or more enumeration types can be set, repeat no more in the embodiment of the invention.
In this step, when the access of notifying access network equipment to preset kind UE limits, can be directed against conventional wireless terminals (for example H2H terminal) separately and insert restriction; Also can be directed against preset kind UE (as: the related terminal type of congested control that the MTC devices communicating is introduced is the preset kind UE such as UE of MTC equipment, low priority traffice like terminal type) separately and insert restriction; But also can start access restriction simultaneously to conventional wireless terminals and preset kind UE (newly-increased jam control function); Thereby can make core net according to different demands, carry out congested control flexibly and effectively, and compatibility that can guarantee agreement.
In the embodiment of the invention, can find out that all kinds of from scope do not have an inclusion relation, has and overlap through the classification of above-mentioned preset kind UE; And from the angle of core net; Possibly in a certain period, limit to several Terminal Types according to demand; As: both limited MTC equipment, also limited the UE of low priority traffice, in order to mate this demand; When the access of notifying access network equipment to preset kind UE through interface signaling limits, can use the IE UE that restriction inserts to needs of BIT STRING type to indicate in this interface signaling.
For example; In the LTE system; In OVERLOAD START message, can introduce Overload Action for Specific UEs information unit, and use this Overload Action for Specific UEs information unit that the information of preset kind UE is notified to access network equipment eNB.Like table 3; OVERLOAD START message shown in the table 4; This Overload Action for Specific UEs information unit is optional appearance, concrete implication and association attributes Overload Action for Specific UEs information unit as shown in table 5.
Table 3
Table 4
Table 5
It should be noted that in practical application the content shown in the table 5 can be adjusted according to actual needs or replenished; For example, in 8 bits, bit 3 is Hypomobility UE; Bit 4 representative roaming UE etc., the situation of each bit can be adjusted arbitrarily according to actual conditions.In addition, total bit number also can define according to actual conditions among the BIT STRING.
In sum, through above-mentioned definition mode, can so that MME according to concrete demand to satisfying certain category feature or simultaneously the UE that satisfies several category features being inserted restriction, with the congested demand for control in the flexible reply practical application; And can be 0 or 1 restriction or the access that does not limit certain type of UE through each bit, and need not make amendment OVERLOAD STOP message.
Need to prove that newly-increased Overload Action for Specific UEs information unit can be increased in the OVERLOAD START message, also can define new S1 interface message separately and comprise this information unit.
Again for example; In the LTE system, can also in OVERLOAD START message, the information unit (that is: the design of another kind of Overload Action for Specific UEs information unit) through enumeration type be notified to access network equipment eNB by the information of preset kind UE.In this case, need to set in advance, and be its corresponding enumerated value of definition in every kind of information unit that is combined in enumeration type that possibly occur to the combination that the various controls that possibly occur insert the UE type.
Remove above-mentioned optimal way (that is: with Overload Action for Specific UEs information unit; Be made as same level IE with Overload Response information unit) outside, also have the another kind of mode that in OVERLOADSTART message, increases Overload Action for Specific UEs information unit can realize inserting restriction to conventional wireless terminals (for example H2H terminal) separately; Also can be directed against preset kind UE (as: the related terminal type of congested control that the MTC devices communicating is introduced separately; Like terminal type is the preset kind UE such as UE of MTC equipment, low priority traffice) insert restriction; But this kind mode can not start the access restriction to conventional wireless terminals and preset kind UE (newly-increased jam control function) simultaneously; The message structure such as the table 6 of this mode are shown in the table 7, table 8.
Table 6
Table 7
Table 8
With table 3; Table 4; Message structure shown in the table 5 is compared, and the attribute with Overload Action in this mode changes optional appearance into, and newly-increased Overload Action for Specific UEs information unit and Overload Action information unit is arranged side by side.Because the attribute of Overload Response is Choice type (promptly can only select its a information unit to occur) at every turn; Overload Action information unit and Overload Action for Specific UEs information unit can only occur one at every turn, therefore can realize inserting restriction to conventional wireless terminals separately; Also can insert restriction to preset kind UE separately, but this kind mode can not start the access restriction to conventional wireless terminals and preset kind UE (newly-increased jam control function) simultaneously.At this moment, Overload Action for Specific UEs information unit also can adopt the mode of enumerating design except using the STRING of BIT shown in the table 8 mode designs, and repeats no more.
In the UMTS system; Corresponding processing mode and LTE system class are seemingly; Just need carry out handled, wherein, can in OVERLOAD message, define the Overload Action for Specific UEs information unit of similar LTE system in OVERLOAD message; Also can define new message separately and be used to transmit this information unit realization function corresponding.Because with the LTE system similarity, concrete message modification mode repeats no more here.
It should be noted that; In the embodiment of the invention, can insert restriction to conventional wireless terminals separately, in order to realize this function; Can be through in OVERLOAD START message, comprising corresponding Overload Action information unit; And through newly-increased information unit Overload Action for Specific UEs is defined as optional appearance, when newly-added information unit Overload Action for Specific UEs does not occur, then according to the congested control of existing protocol definition carrying out; At this moment, can realize inserting to conventional wireless terminals separately the function of restriction.Certainly also can in OVERLOADSTART message, comprise other information in the practical application,, give unnecessary details no longer in detail at this as long as can realize corresponding function.In addition; Realization described in the embodiment of the invention inserts restriction to conventional wireless terminals separately; Two kinds of understandings can be arranged: a kind of understanding is only the conventional wireless terminals except that preset kind UE to be inserted restriction (as: when MME refuses non-emergent caller data (mo-data) access through sending current overload action IE indication eNB; This restriction does not comprise preset kind UE (as: MTC equipment), does not promptly refuse non-emergent caller data (mo-data) access that preset kind UE (as: MTC equipment) initiates); Another kind of understanding is that all conventional wireless terminals that comprise preset kind UE are inserted restriction (as: when MME refuses non-emergent caller data (mo-data) access through sending current overload action IE indication eNB; This restriction comprises the access restriction to preset kind UE (as: MTC equipment), promptly also refuses non-emergent caller data (mo-data) access that preset kind UE (as: MTC equipment) initiates).Which kind of adopts can arrange, can be by equipment of the core network through the explicit signaling indication.In the practical application, because preset kind UE has lower priority, so second kind of understanding is a kind of optimal way.
In the embodiment of the invention; Can insert restriction to preset kind UE separately; Because Overload Action information unit attribute is essential appearance (M), consider from the compatible angle of agreement, can not the information unit of M attribute be revised as O (optional appearance); Even therefore equipment of the core network need adopt certain mode to make access network equipment receive Overload Action information unit, being read as does not need corresponding access control yet.
In order to realize this function; In the embodiment of the invention; Can in OVERLOAD START message, increase indication information; Make access network equipment (like eNB, Relay, HeNB) when receiving Overload Action information unit, can be read as does not need corresponding access control, the sketch map situation that Overload Action protocol element is made amendment as shown in table 9.
Table 9
As shown in table 9; In Overload Action information unit, increase the definition of No Action; When equipment of the core network MME need not insert restriction to conventional wireless terminals; Then Overload Action information unit can value be No Action; After access network equipment eNB received this information, need not had any operation (perhaps Overload Action information unit is not operated and the specified message unit is operated) to this Overload Action information unit, only needed according to Overload Action for Specific UEs information unit the control that specified terminal type inserts to be got final product.
In addition; In the practical application; MME can also increase No Action indication and at least one the 2nd No Action indication in the information unit (like Overload Action information unit) of the OVERLOAD of S1 interface START message; ENB is when receiving OVERLOAD START message in indication; Overload Action information unit is not operated and specified message unit (be other information units that define in the reality, these other information units can define according to actual conditions) operated.
In the embodiment of the invention; Can also start access restriction simultaneously to conventional wireless terminals and preset kind UE; In this case, Overload Action information unit and Overload Action for Specific UEs information unit occur realizing this function simultaneously.
Concrete, behind the interface signaling that receives from equipment of the core network, access network equipment can obtain preset kind UE from interface signaling, thereby can the access of this preset kind UE be limited.
In the embodiment of the invention; When receiving OVERLOAD START message; If when having increased No Action in the Overload Action information unit; Then this moment, access network equipment need not have any operation to the IE of Overload Action information unit, only needed according to Overload Action for Specific UEs information unit the control that specified terminal type inserts to be got final product.
In sum; In the embodiment of the invention; Equipment of the core network inserts to the UE that possesses certain characteristic through interface signaling notice access network equipment and limits, and can insert restriction, also can insert restriction, can also insert restriction to conventional wireless terminals and preset kind UE simultaneously to preset kind UE separately to conventional wireless terminals separately, thereby make core net according to different demands; Carry out congested control flexibly and effectively, and compatibility that can guarantee agreement.
