The UE that the embodiment of the invention is mentioned possibly be that the people maybe possibly be machine to machine (M2M, a Machine to Machine) subscriber equipment to people (H2H, Human to Human) subscriber equipment, or the UE of other type.Wherein, the M2M subscriber equipment can be claimed Machine Type communication equipment (MTC Device, Machine Type Communications Device).

At first from the angle of mobile management network element, the present invention program is introduced below.

The present invention transmits an embodiment of the method for carrying attribute, can comprise: mobile management network element obtains the carrying of user equipment (UE) or the priority attribute of the APN that contracts is confirmed policy information; Carry the non-access layer information that this priority attribute is confirmed policy information to this UE transmission.

Referring to Fig. 1-a, concrete steps can comprise:

A1, mobile management network element obtain the carrying of user equipment (UE) or the priority attribute of the APN that contracts is confirmed policy information;

Wherein, Above-mentioned priority attribute is confirmed policy information; Can be any information that can make UE determine the priority attribute of its one or more carryings or the APN that contracts, this loading priority attribute confirms that policy information for example can comprise the one or more carryings of UE or the priority indication (promptly directly indicating priority) of signatory APN.And/or; (priority level can comprise Three Estates such as basic, normal, high to the various priority levels of carrying of network side definable or APN; Also have more multipriority grade) corresponding time delay tolerance, packet loss or service quality (Qos; Quality of Service) span (for example; Some service quality rating sign (QCI of definable; QoS Class Identifier) for low priority, some QCI are high priority, and the like), and mobile management network element confirms that to the carrying of this UE of UE transmission or the priority attribute of the APN that contracts policy information also can comprise: the indication information of the scopes such as Qos, time delay or packet loss that at least a priority level is corresponding.

Under a kind of application scenarios; Mobile management network element can obtain the carrying of UE in several ways or the priority attribute of the APN that contracts is confirmed policy information; What for example mobile management network element can be according to subscription data, carrier policy and the local policy of UE is at least a; Obtain said UE carrying or the priority attribute of signatory APN APN confirm policy information (what for example mobile management network element can be according in the information such as subscription data, carrier policy and local policy of this UE be at least a; Determine the one or more carryings of this UE or the priority attribute of the APN that contracts, and generation comprises, and this UE carries or the priority attribute of the priority indication of the APN that contracts is confirmed policy information).Perhaps, mobile management network element also can be confirmed policy information from gateway device, home subscriber server (HSS, Home Subscriber Server) or one or more carryings of this UE of miscellaneous equipment acquisition or the priority attribute of the APN that contracts.

A2, mobile management network element send the non-access layer information that the priority attribute that carries the carrying of this UE or the APN that contracts is confirmed policy information to this UE.

In practical application, mobile management network element can for example be confirmed policy information through Non-Access Stratum (NAS, nonAccess stratum) message to the priority attribute that UE transmits its carrying or the APN that contracts based on multiple flow process.For instance; Mobile management network element can transmit the priority attribute of its carrying or the APN that contracts and confirm policy information based on attachment flow, attachment removal flow process, tracing section updating flow process, bearing modification flow process, load bearing deactivation flow process or other flow process etc. of UE to UE.UE then can receive the NAS message from MME in attachment flow, attachment removal flow process, tracing section updating flow process, bearing modification flow process, load bearing deactivation flow process or other flow process, the carrying of this UE that the acquisition mobile management network element sends from this NAS message or the priority attribute of the APN that contracts are confirmed policy information.

For instance; Mobile management network element can send the priority attribute carry the carrying of this UE or the APN that contracts to UE, and to confirm to accept adhering to of policy information message (be that mobile management network element can be based on the attachment flow of UE; Confirm policy information to UE its carrying of transmission or priority attribute); Perhaps; Mobile management network element can send to UE and activate special-purpose evolution grouping domain system (EPS, Evolved Packet System) bearer context request message, and this activates, and special-purpose EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, mobile management network element can send deexcitation EPS bearer context request message to UE, and this deexcitation EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, mobile management network element can send to UE and revise EPS bearer context request message, and this modification EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, mobile management network element can send the grouped data network PDN to UE and accept message, and this PDN accepts that message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, mobile management network element can send the PDN connection refused message to UE, and this PDN connection refused message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, mobile management network element can send tracing section updating to UE and accept message, and this tracing section updating accepts that message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information.It is understandable that mobile management network element also can pass through other one or more message, transmit the priority attribute of its carrying or the APN that contracts to UE and confirm policy information, enumerate no longer one by one here.

Under this scene; UE (possibly be when Idle state changes connected state over to, to initiate during follow-up initiation service request; Also possibly be to initiate when being in connected state), can be according to carrying or the priority attribute of the APN that contract confirmed policy information, the business of definite initiation based on carrying or the priority of APN; And can generate the corresponding switch-in attribute indication of definite priority; Send the message of carrying this switch-in attribute indication to network side, be convenient to network side like this and this business of UE initiation carried out access control according to the switch-in attribute indication.

Can find out; In the present embodiment since mobile management network element through NAS message; The priority attribute of the carrying of UE or the APN that contracts is confirmed that policy information passes to UE; Make UE to confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; And the corresponding switch-in attribute indication of the priority that can generate definite carrying; And send the message carry this switch-in attribute indication to network side, and then the business that makes network side initiate UE according to this switch-in attribute indication is carried out access control and is become possibility.This mechanism helps clear and definite its of UE and initiates the priority of professional institute based on carrying; And then make clear and definite its service access control logic of UE indication network side become possibility; Handle the reasonability that UE initiates business so help improving network side, help strengthening the experience of user application-specific.

From the angle of user equipment (UE), the present invention program is introduced below.

An embodiment of Business Initiator's method of the present invention can comprise: the non-access layer information that user equipment (UE) receiving mobility managed network element sends, and this non-access layer information carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information; Confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; Generate the corresponding switch-in attribute indication of this priority of confirming; Send the message that carries this switch-in attribute indication to network side, so that network side carries out access control according to this switch-in attribute indication to the said business that said UE initiates.

Referring to Fig. 1-b, concrete steps can comprise:

The non-access layer information that B1, user equipment (UE) receiving mobility managed network element send;

Wherein, this non access stratum NAS message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information;

In practical application, mobile management network element can transmit the loading priority attribute through NAS message to UE and confirm policy information based on multiple flow process.For example, mobile management network element can transmit the loading priority attribute to UE and confirm policy information based on attachment flow, attachment removal flow process, tracing section updating flow process, bearing modification flow process, load bearing deactivation flow process or other flow process etc. of UE.UE then can receive the NAS message from MME in attachment flow, attachment removal flow process, tracing section updating flow process, bearing modification flow process, load bearing deactivation flow process or other flow process, the loading priority attribute that from this NAS message, obtains the mobile management network element transmission is confirmed policy information.

For instance; It (is that mobile management network element can be based on the attachment flow of UE that but carrying that carries this UE that UE receiving mobility managed network element sends or the priority attribute of the APN that contracts confirm to accept adhering to of policy information message; Confirm policy information to UE its carrying of transmission or priority attribute); Perhaps; But the special-purpose evolution grouping domain system of the activation that UE receiving mobility managed network element sends EPS bearer context request message, this activates, and special-purpose EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, but the deexcitation EPS bearer context request message that UE receiving mobility managed network element sends, and this deexcitation EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, but the modification EPS bearer context request message that UE receiving mobility managed network element sends, and this modification EPS bearer context request message carries the carrying of above-mentioned UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, but the grouped data network PDN that UE receiving mobility managed network element sends is accepted message, and this PDN accepts that message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, but the PDN connection refused message that UE receiving mobility managed network element sends, and this PDN connection refused message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information; Perhaps, but the tracing section updating that UE receiving mobility managed network element sends is accepted message, and this tracing section updating accepts that message carries the carrying of this UE or the priority attribute of the APN that contracts is confirmed policy information.It is understandable that; Mobile management network element also can pass through other one or more message; Transmit the priority attribute of its carrying or the APN that contracts to UE and confirm policy information; UE then obtains the loading priority attribute of mobile management network element transmission and confirms policy information from this NAS message, enumerate no longer one by one here.

B2, UE confirm policy information according to the priority attribute of its carrying or the APN that contracts, the business of confirm initiating based on carrying or the priority of APN;

In practical application, UE confirms policy information according to its carrying of mobile management network element transmission or the priority attribute of the APN that contracts, the priority of confirmable one or more carryings or APN.

For example, if priority attribute confirms that policy information comprises: the priority attribute indication of one or more APN that UE is signatory, then UE confirms policy information according to this priority attribute, can determine the priority of all corresponding carryings of its signatory one or more APN.Perhaps, if the loading priority attribute confirms that policy information comprises: the priority attribute indication of one or more carryings that UE sets up, then UE confirms policy information according to this priority attribute, can determine the priority of one or more carryings of foundation.Be appreciated that; Priority attribute confirms can comprise in the policy information that the signatory part priority level APN of UE (for example comprises height/medium priority APN; Or in/low priority APN) priority attribute indication; And/or; Comprise the part priority level that UE sets up carry (for example comprise that height/medium priority carries, or in/low priority carries) the priority attribute indication, and the priority attribute indication that does not comprise residue priority level APN (for example not comprising low priority APN or high priority APN) or carry (for example not comprising that low priority carries or high priority carries) is (wherein; UE can be defaulted as this part A PN or carrying is certain priority); Under this scene, the priority of all APN (or carrying) is determined in the priority attribute indication of the part priority level APN (or carrying) that UE can confirm to comprise in the policy information according to priority attribute.

For instance; Current 3 APN (like APN1, APN2 and APN3) that contracted of UE, wherein, if mobile management network element confirms that APN1 is a low priority; APN2 is a high priority; APN3 is a high medium priority, and at this moment, mobile management network element confirms that to the priority attribute that UE transmits policy information can comprise: indication APN1 is that low priority, APN2 are that high priority, APN3 are the priority indication information of high medium priority; Perhaps; Can comprise that indication APN2 is that high priority, APN3 are the priority indication information of high medium priority; But do not comprise that indication APN1 is the priority indication information of low priority; And this moment; UE then can confirm that it is that high priority, APN3 are high medium priority that policy information is determined APN2 according to this priority attribute, and can give tacit consent to that to determine APN1 be low priority (be UE and network side fix on priority attribute approximately confirm not carry in the policy information that the APN of respective priority attribute indication is defaulted as is the low priority attribute); Perhaps; Mobile management network element confirms that to the priority attribute that UE transmits policy information can comprise: indication APN1 is that low priority, APN3 are the priority indication information of high medium priority but does not comprise that indication APN2 is the priority indication information of high priority; And this moment; UE then can confirm that it is that low priority, APN3 are high medium priority that policy information is determined APN1 according to this priority attribute; And can give tacit consent to that to determine APN2 be high priority (be UE and network side fix on priority attribute approximately confirm not carry in the policy information that the APN of respective priority attribute indication is defaulted as is the high priority attribute), by that analogy.

Again for instance; If mobile management network element confirms that to the loading priority attribute that UE transmits policy information comprises: the indication information of the spans such as Qos, time delay tolerance or packet loss that the carrying of various priority levels (for example high/medium/low) is corresponding; Then UE can compare related parameter values of carrying and the corresponding spans such as Qos, time delay tolerance or packet loss of various priority levels carrying, and then can determine the priority of carrying.

It is understandable that; The priority attribute of the APN that UE is signatory can be regarded the priority attribute of all corresponding carryings of this APN as, that is to say; When UE determines the priority attribute of its certain signatory APN, also just be equivalent to determine the priority attribute of all corresponding carryings of this APN.

B3, UE generate the corresponding switch-in attribute indication of confirming of priority;

Wherein, switch-in attribute indication can indicate the priority (for example can indicate access priority grade, time delay tolerance grade, packet loss grade, QoS grade etc.) of access, is appreciated that access priority is high more then can more preferentially insert.

Wherein, the business of the indication of this switch-in attribute and the UE initiation of determining based on the priority of APN or carrying corresponding.For example, if determine UE initiate professional based on APN or the priority of carrying be high priority, then the access priority grade shown in the switch-in attribute indication indication that generates of UE can be high priority; If determine UE initiate professional based on APN or the priority of carrying be medium priority, then the access priority grade shown in the switch-in attribute indication indication that generates of UE also can be middle access priority (or being height/low priority); If the UE that confirms initiate professional based on APN or the priority of carrying be low priority, then the access priority grade shown in the switch-in attribute indication indication that generates of UE also can be low priority, for the scene that a plurality of priority levels are arranged, can be by that analogy.

B4, UE send the message that carries this switch-in attribute indication to network side, so that network side carries out access control according to this switch-in attribute indication to the business that UE initiates.

In practical application, the switch-in attribute indication that UE generates can be to make network equipment determine any information of professional access priority grade.

Wherein, UE for example can control (RRC at Radio Resource; Radio Resource Control) carries this switch-in attribute indication in message (connecting completion message etc.) or other message, with switch-in attribute to the access network element indicating services like RRC connection request message or RRC; And/or, can in NAS message (for example business request information, Attach Request message or location update request message etc.), carry this switch-in attribute indication, with switch-in attribute to the mobile management network element indicating services.

Further, access network element can receive the message of carrying the switch-in attribute indication (connecting completion message etc. like RRC connection request message or RRC) or other message that UE sends in business initiation process; Access network element can carry out access control to the business that UE initiates according to this switch-in attribute indication.For instance; If the indicated access priority grade of this switch-in attribute indication is high access priority; Then can preferentially insert should business for access network element; If the indicated access priority grade of this switch-in attribute indication is low access priority, then when network congestion, can select refusal to insert or postpone to insert should business etc. for access network element.

In addition, mobile management network element can receive the NAS message of carrying the switch-in attribute indication that UE sends (like PND connection request message etc.) in business initiation process; Mobile management network element can carry out access control to the business that UE initiates according to this switch-in attribute indication

Can find out; In the present embodiment since mobile management network element through NAS message; The priority attribute of the carrying of UE or the APN that contracts is confirmed that policy information passes to UE, and UE can confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; Generate the corresponding switch-in attribute indication of priority of the carrying of confirming; And send the message carry this switch-in attribute indication to network side, making network side to carry out access control according to the business that this switch-in attribute indication is initiated UE becomes possibility.This mechanism makes clear and definite its of UE initiate the priority of professional institute based on carrying; UE makes that through indication network side can clear and definite its service access control logic; Handle the reasonability that UE initiates business so help improving network side, help strengthening the experience of user application-specific.

From the angle of access network element, the present invention program is introduced below.

An embodiment of service access control method of the present invention can comprise: access network element receives the message of carrying the switch-in attribute indication that UE sends in business initiation process; Indication is carried out access control to this business that UE initiates according to this switch-in attribute, and wherein, the APN that this switch-in attribute indication is issued according to mobile management network element by UE or the priority attribute of carrying confirm that policy information generates.

Referring to Fig. 1-c, concrete steps can comprise:

C1, access network element receive the message of carrying the switch-in attribute indication that UE sends in business initiation process;

Wherein, access network element can receive the RRC message of carrying the switch-in attribute indication (connecting completion message like RRC connection request message or RRC) or other message that UE sends in business initiation process.

It is understandable that, in the message of sending, carrying switch-in attribute indication bit position when UE also can be chosen in high access priority grade, and when low access priority grade, adopt acquiescence to indicate to access network element (or mobile management network element); Promptly when high access priority; UE carries switch-in attribute indication bit position and indicates high access priority grade in message, and when hanging down access priority, UE does not carry switch-in attribute indication bit position in message; It is the low access priority grade of indication that access network element this moment (or mobile management network element) is defaulted as UE; Or UE also can be chosen in when hanging down access priority and in the message of sending to access network element, carry switch-in attribute indication bit position, and when high access priority, adopts the acquiescence indication; Promptly when high access priority; UE does not carry switch-in attribute indication bit position in message, it is the high access priority of indication that access network element this moment (or mobile management network element) is defaulted as UE, by that analogy.

Need to prove; UE is before access network element is initiated RRC connection foundation request; The expansion that can read earlier in the cell broadcast messages inserts level limit (Extended Access Class Barring) and inserts level limit (Access Class Barring); And according to expansion access level limit and access level limit; Judge whether allow the current business that will initiate by the current wireless network (possibly be that low priority traffice (the for example high business of time delay tolerance) inserts, not allow this service access (possibly be access network element work as preload heavier) if judge the current wireless network, then can suspend initiation should business.

C2, access network element carry out access control according to this switch-in attribute indication to the business that UE initiates.

For instance; If the indicated access priority of this switch-in attribute indication is high access priority; Then access network element can preferentially insert; If the indicated access priority of this switch-in attribute indication is low access priority, then access network element can be selected refusal to insert when network congestion or postpone access etc.

Can find out, in the present embodiment because the APN that UE issues according to mobile management network element or the priority attribute of carrying are confirmed policy information, the business of confirming to initiate based on APN or the priority of carrying; And the switch-in attribute that generates the priority correspondence of confirming is indicated; Send the message of carrying this switch-in attribute indication to access network element, access network element can carry out access control to the business that UE initiates according to this switch-in attribute indication.The service access control logic of access network element that this mechanism is clear and definite is handled the reasonability that UE initiates business so help improving access network element, helps strengthening the experience of user to application-specific.

Embodiment one

For ease of better understanding the technical scheme of the embodiment of the invention, mainly describe in the present embodiment to be embodied as example in the LTE communication system.

Be primarily aimed in the present embodiment when UE adheres to; Network side can be according in the information such as subscription data, carrier policy and local policy of this UE one or more; Determine the priority attribute of one or more APN that priority attribute or this UE contracted of one or more carryings of this UE; And this priority attribute information passed to UE, so that UE and access network element (or MME) carry out the professional access control of this UE according to this priority attribute information.

Can comprise referring to Fig. 2, concrete steps:

201, UE sends Attach Request message to MME.

Under a kind of application scenarios; In carrying out the network attachment process; UE can through RRC message to eNB indicate with the APN of this UE default configuration or carry corresponding access priority (for example can RRC set up request message or RRC set up to accomplish carry the switch-in attribute indication in the message); Perhaps UE can indicate with the APN of this UE default configuration or carries corresponding access priority (here can at Attach Request message) etc. to MME through NAS message; Wherein, with the APN of this UE default configuration or to carry corresponding access priority possibly be low priority (higher like the time delay tolerance), high priority (lower like the time delay tolerance), medium priority or other access priority.In addition, if UE goes up not configuration and default configuration APN or carries corresponding access priority, then UE can not indicate access priority to eNB or MME yet.

202, MME receives the above-mentioned Attach Request message from UE, and MME obtains the subscription data about this UE from HSS.

Under a kind of application scenarios; For situation from the priority attribute of one or more carryings to UE that need transmit; MME can determine the priority attribute of these one or more carryings, and priority attribute comprises for example time delay tolerance, packet loss or QoS etc. or other service attribute.Wherein, MME can determine the priority attribute of these several carryings according to the subscription data of this UE that obtains from HSS, the corresponding information such as APN, operator's collocation strategy and local policy one or more.

For situation from the priority attribute (priority attribute of the APN here also can be regarded the priority attribute of all corresponding carryings of this APN as) of one or more APN to UE that need transmit, the last priority attribute information that can preserve each signatory APN of this UE of HSS; For instance, current 3 APN (like APN1, APN2 and APN3) that contracted of UE, wherein, APN1 possibly be a low priority, and APN2 possibly be a high priority, and APN3 possibly be a high medium priority.Which APN is the priority attribute information of each APN that UE is signatory for example can indicate is low priority, and which APN is a high priority, for the situation that a plurality of priority levels are arranged, by that analogy.

Certainly, MME also can determine the priority attribute of some or a plurality of APN that UE is signatory, for example can determine its time delay tolerance, Qos, packet loss or other service attribute.MME can determine the priority attribute of this APN according in the information such as the subscription data of HSS, corresponding APN, operator's collocation strategy and local policy one or more.It is understandable that MME also can determine the priority attribute of signatory all APN of UE, such as signatory 3 APN (like APN1, APN2 and APN3) of UE; MME can be according in the information such as subscription data, operator's collocation strategy and local policy of this UE on the HSS one or more, and determining APN1 is normal priority, and APN2 is a low priority; APN3 is a high priority; By that analogy, for the situation that a plurality of priority levels are arranged, by that analogy.

203, MME sends to gateway device and sets up conversation request message;

204, gateway device is set up default bearer, and sets up the conversation request response message to the MME transmission;

Under a kind of application scenarios; If UE has carried APN information in above-mentioned Attach Request message; Then MME initiates to set up gateway (SGW in step 203～204; Serving Gateway) and grouped data network gateway (PGW, Packet Data Network Gateway) about the default bearer of this APN.Otherwise; MME initiates to set up the default bearer of the signatory default APN of this UE, and wherein, this sets up bearing identification information, the APN information of portability default bearer in the conversation request message; Perhaps can also carry the priority attribute information of this carrying or APN etc.; Wherein, this priority attribute information can perhaps also can be confirmed by MME from the indication of UE.

In addition; PGW, SGW or PCRF (Policy and Charging Rules Function; Strategy and charging rule functions) entity also can be according to APN information, and one or more in the information such as carrier policy that disposes on this network element and local policy determine the priority attribute information of this carrying or APN; And can this priority attribute information be passed to MME through setting up conversational response message, MME also can obtain the priority attribute information of this carrying or APN in view of the above.

It is understandable that; The priority attribute of the carrying of UE or signatory APN can be confirmed by the some nodes in the core net (for example MME, PGW, SGW or PCRF entity etc.); Also can confirm jointly by certain several node; Wherein, this one or several node can determine according to one or more parameters in the information such as relevant subscription data, APN information, carrier policy and local policy of HSS preservation jointly.

In addition, MME also can be through setting up conversation request message, and the APN list information that UE is signatory passes to PGW, and this sets up the priority attribute information of also the signatory APN of portability UE in the conversation request message.

205, MME passes to UE with the priority attribute information of this APN or carrying;

Wherein, MME receive from gateway device set up the conversation request response message after, confirm that the default bearer of this APN set up to be accomplished, MME can pass through NAS message, and the priority attribute information of this APN or carrying is passed to UE.For instance, MME can accept message through adhering to, and the priority attribute information of APN or carrying is passed to UE.

In practical application; If MME is a priority attribute information (the priority attribute information that can comprise current APN) from APN to UE that transmit; For example; MME can increase an attribute indication field in the default EPS bearer context request of the activation in the attachment response message (ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST), utilize the attribute indication field to carry the priority attribute information of APN, so that it is passed to UE.Wherein, It is low priority (as indicating high time delay tolerance) that this attribute indication field for example can be indicated this APN, perhaps, and when this APN is not low priority (for example low time delay tolerance); Network side also can not carry indication bit in message; At this moment, it is normal priority or high priority that UE is defaulted as this APN, and operates according to normal mode; Perhaps, when this APN was low priority, network side also can not carry indication bit in message, and at this moment, it is low priority that UE is defaulted as this APN, by that analogy.

In addition, MME also can be carried at attachment response message with the signatory APN attribute list of UE.Can record APN tabulation and corresponding priorities attribute indication information thereof in this APN attribute list.

For instance.It is that normal priority, APN3 are high priority for low preferential, APN2 that UE contract APN1, APN2 and APN3, APN attribute list indicate APN1.In addition; Also can include only the APN tabulation of low priority (like high time delay tolerance) attribute in the APN attribute list; Perhaps, also can include only the APN tabulation of high priority or normal priority attribute in the APN attribute list, UE can determine the priority attribute of all signatory APN in view of the above.

In addition, if MME transmits the priority attribute information of carrying to UE:

For example; MME transmits the priority attribute of current carrying to UE; MME can increase an attribute indication field in the default EPS bearer context request of the activation in the attachment response message, utilize this attribute indication field to carry the priority attribute information of carrying, so that it is passed to UE.Wherein, This attribute indication field for example can be designated as low priority (like high time delay tolerance), perhaps, and when this carrying is not low priority (for example low time delay tolerance); MME can not carry above-mentioned attribute indication field in message; At this moment, UE is defaulted as this and is carried as normal priority or high priority, and operates according to normal mode.

Again for example, which Qos span network side can define is low priority, and those which Qos spans are high priority etc., for example defines which QCI and is low priority business; Perhaps also can define low preferential carrying that be carried as in which time delay or the packet loss scope; MME can pass to UE with the priority attribute strategy; UE judges voluntarily which is carried as low preferential the carrying; Which is carried as high priority carries, and UE specifically can judge the priority of this carrying according to the Qos of each carrying.

206, UE sends to MME and adheres to completion message.

207, follow-up UE is through initiating service request when Idle state converts connected state into; Or when connected state is initiated service request; Can according to this service request to initiate professional based on APN or the priority of carrying; The generation switch-in attribute is indicated, and sends the message of carrying this switch-in attribute indication to network side, is convenient to network equipment like this and according to this switch-in attribute indication this business that UE initiates is carried out access control.

Wherein, the access priority that indicates of this switch-in attribute and this business based on the priority of APN or carrying corresponding.

For example, UE passes to eNB through RRC message (for example RRC sets up request message or message etc. is accomplished in RRC foundation) with the switch-in attribute indication, and whether eNB can allow the service access of this UE initiation according to the indication of the switch-in attribute in RRC message decision.In addition, UE also can pass through NAS message, and the indication of this switch-in attribute is passed to MME, to MME indicate this business institute based on APN or the priority of carrying, and whether MME also can allow the service access of this UE initiation according to the indication of the switch-in attribute in message decision.

Can find out; In the present embodiment since MME based on the attachment flow of UE; Accept message the priority attribute of the carrying of UE or the APN that contracts is confirmed that policy information passes to UE through adhering to; UE can confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; Generate the corresponding switch-in attribute indication of priority of the carrying of confirming; And send the message carry this switch-in attribute indication to network side, make network side to carry out access control to the business that UE initiates according to this switch-in attribute indication.This mechanism makes clear and definite its of UE initiate the priority of professional institute based on carrying; UE makes that through indication network side can clear and definite its service access control logic; Handle the reasonability that UE initiates business so help improving network side, help strengthening the experience of user application-specific.

Embodiment two

Be primarily aimed at UE obtains APN or carrying before from network side priority attribute information in the present embodiment; UE uses default configuration (like high priority or low priority) or normal the access earlier when initiating business; Insert the priority attribute that determines its APN or carrying afterwards by network side; And pass to this UE, so that UE and access network element (or MME) carry out the professional access control of this UE according to this priority attribute information.

Referring to Fig. 3, concrete steps can comprise:

301, UE has been registered to network; When needs are set up the PDN connection of corresponding certain APN; UE sends PDN connection request (PDN Connectivity Request) to MME, and UE can use default configuration (like height/low priority) or insert according to normal mode when initiating service request.

302, MME receives the PDN connection request from UE, and MME sends to gateway device (SGW and PGW) and sets up conversation request message.

303, MME receives and to set up the conversation request response message from gateway device;

Wherein, MME receive from gateway device set up the conversation request response message after, confirm that the default bearer of this APN set up to be accomplished.

Under a kind of application scenarios, if UE carried APN information in above-mentioned PDN connection request, then MME initiates to set up SGW and the PGW default bearer about this APN in step 302～303.Wherein, This sets up bearing identification information, the APN information of portability default bearer in the conversation request message, perhaps can also carry the priority attribute information of this carrying or APN etc., wherein; This priority attribute information can perhaps also can be confirmed by MME from the indication of UE.

In addition; PGW, SGW or PCRF entity also can be according to APN information; In the information such as carrier policy that disposes on this network element and local policy one or more; Determine the priority attribute information of this carrying or APN, and can this priority attribute information be passed to MME through setting up conversational response message, MME also can obtain the priority attribute information of this carrying or APN in view of the above.

304, MME passes to UE through NAS message with the priority attribute information of this APN or carrying;

In practical application, if MME is a priority attribute information (the priority attribute information that can comprise current APN) from APN to UE that transmit.For example, MME can utilize the attribute indication field to carry the priority attribute information of APN, so that it is passed to UE in the increase attribute indication field in PDN ConnectivityAccept (PDN the connects acceptance) message.Wherein, It is low priority (as indicating high time delay tolerance) that this attribute indication field for example can be indicated this APN, perhaps, and when this APN is not low priority (for example low time delay tolerance); Network side also can not carry indication bit in message; At this moment, it is normal priority or high priority that UE is defaulted as this APN, and operates according to normal mode; Perhaps, when this APN was low priority, network side also can not carry indication bit in message, and at this moment, it is low priority that UE is defaulted as this APN, by that analogy.

For example; MME transmits the priority attribute of current carrying to UE; MME can accept to increase an attribute indication field in the default EPS bearer context request of activation in the message at PDN, utilizes this attribute indication field to carry the priority attribute information of carrying, so that it is passed to UE.Wherein, This attribute indication field for example can be designated as low priority (like high time delay tolerance); Perhaps working as this carrying is not low priority (for example low time delay tolerance), and MME can not carry above-mentioned attribute indication field in message, at this moment; UE is defaulted as this and is carried as normal priority or high priority, and operates according to normal mode.

305, follow-up UE is through initiating service request when Idle state converts connected state into; Or when connected state is initiated service request; Can according to this service request to initiate professional based on APN or the priority of carrying; The generation switch-in attribute is indicated, and sends the message of carrying this switch-in attribute indication to network side, is convenient to network equipment like this and according to this switch-in attribute indication this business that UE initiates is carried out access control.

Can find out; In the present embodiment since MME based on the PDN connection building process; The priority attribute of the carrying of UE or the APN that contracts is confirmed that policy information passes to UE, and UE can confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; Generate the corresponding switch-in attribute indication of priority of the carrying of confirming; And send the message carry this switch-in attribute indication to network side, make network side to carry out access control to the business that UE initiates according to this switch-in attribute indication.This mechanism makes clear and definite its of UE initiate the priority of professional institute based on carrying; UE makes that through indication network side can clear and definite its service access control logic; Handle the reasonability that UE initiates business so help improving network side, help strengthening the experience of user application-specific.

In addition, referring to Fig. 4, also can set up flow process, the priority attribute information of APN or carrying is passed to UE through the dedicated bearer that PGW initiates.

401, PGW sends to create to MME and carries request (Create bearer Request) message.

Wherein, PGW or SGW or PCRF entity also can be according to APN information; Wherein one or more such as carrier policy and local policy determine the priority attribute of this dedicated bearer, and the priority attribute of this dedicated bearer is carried in the Create bearer Request message passes to MME; Certainly, go back other the signatory APN of portability UE or the priority attribute information of carrying in this message.

402, MME sends Activate dedicated EPS bearer context request (activating special-purpose EPS bearer context request) message to UE.

Wherein, specifically can in Activate dedicated EPS bearer context request message, increase the attribute indication field, utilize this attribute indication field to carry the priority attribute information of carrying, so that it is passed to UE.Wherein, This attribute indication field for example can be designated as height/low priority, perhaps, and when this carrying is not low priority (for example low time delay tolerance); MME also can not carry above-mentioned attribute indication field in message; At this moment, UE is defaulted as this and is carried as normal priority or high priority, and can operate according to normal mode.Certainly, go back other the signatory one or more APN of portability UE or the priority attribute information of carrying in the above-mentioned Activate dedicated EPS bearer context request message.

403, UE sends the special-purpose EPS bearer context of above-mentioned activation to MME and accepts message;

404, MME sends to create to PGW and carries response (Create bearer Response) message.

405, follow-up UE is through initiating service request when Idle state converts connected state into; Or when connected state is initiated service request; Can according to this service request to initiate professional based on APN or the priority of carrying; The generation switch-in attribute is indicated, and sends the message of carrying this switch-in attribute indication to network side, is convenient to network equipment like this and according to this switch-in attribute indication this business that UE initiates is carried out access control.

Can find out; In the present embodiment because MME sets up flow process based on the dedicated bearer that PGW initiates; The priority attribute of the carrying of UE or the APN that contracts is confirmed that policy information passes to UE; UE can confirm policy information according to this priority attribute, the business of confirm initiating based on carrying or the priority of APN; Generate the corresponding switch-in attribute indication of priority of the carrying of confirming; And send the message carry this switch-in attribute indication to network side, make network side to carry out access control to the business that UE initiates according to this switch-in attribute indication.This mechanism makes clear and definite its of UE initiate the priority of professional institute based on carrying; UE makes that through indication network side can clear and definite its service access control logic; Handle the reasonability that UE initiates business so help improving network side, help strengthening the experience of user application-specific.
