Can find out, because mobile management network element passes through NAS message in the present embodiment, by the carrying of UE or the priority attribute determination policy information of the APN that contracts pass to UE, make UE can according to this priority attribute determination policy information, determine the business initiated based on carrying or the priority of APN; And the switch-in attribute instruction that the priority that can generate the carrying determined is corresponding; And send the message of carrying the instruction of this switch-in attribute to network side, and then network side is made to carry out access control according to the instruction of this switch-in attribute become possibility to the business that UE initiates.This mechanism be conducive to UE its initiation business clear and definite based on carrying priority, and then make UE indication network side its service access control logic clear and definite become possibility, so be conducive to improving the reasonability that network side process UE initiates business, be conducive to strengthening user to the experience of application-specific.

Below from the angle of user equipment (UE), the present invention program is introduced.

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, this non-access layer information carry this UE carrying or the priority attribute determination policy information of the APN that contracts; According to this priority attribute determination policy information, determine the business initiated based on carrying or the priority of APN; Generate the switch-in attribute instruction that this priority determined is corresponding; The message carrying the instruction of this switch-in attribute is sent, so that network side carries out access control according to the instruction of this switch-in attribute to the described business that described UE initiates to network side.

See 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 carry this UE carrying or the priority attribute determination policy information of the APN that contracts;

In actual applications, mobile management network element based on multiple flow process, can transmit loading priority attribute determination policy information by NAS message to UE.Such as, mobile management network element based on the attachment flow of UE, attachment removal flow process, tracing section updating flow process, bearing modification flow process, load bearing deactivation flow process or other flow process etc., can transmit loading priority attribute determination policy information 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, obtains the loading priority attribute determination policy information that mobile management network element transmits from this NAS message.

For example, UE can the carrying carrying this UE that sends of receiving mobility managed network element or the attachment of priority attribute determination policy information of the APN that contracts accept message (namely mobile management network element can based on the attachment flow of UE, its carrying or priority attribute determination policy information is transmitted) to UE, or, UE can receiving mobility managed network element send activation special evolution grouping domain system EPS bearer context request message, this activation special EPS bearer context request message carry above-mentioned UE carrying or the priority attribute determination policy information of the APN that contracts, or UE can the deexcitation EPS bearer context request message that sends of receiving mobility managed network element, this deexcitation EPS bearer context request message carry above-mentioned UE carrying or the priority attribute determination policy information of the APN that contracts, or UE can the amendment EPS bearer context request message that sends of receiving mobility managed network element, this amendment EPS bearer context request message carry above-mentioned UE carrying or the priority attribute determination policy information of the APN that contracts, or UE can accept message by the grouped data network PDN that sends of receiving mobility managed network element, this PDN accept message carry this UE carrying or the priority attribute determination policy information of the APN that contracts, or UE can the PDN connection refused message that sends of receiving mobility managed network element, this PDN connection refused message carry this UE carrying or the priority attribute determination policy information of the APN that contracts, or UE can accept message by the tracing section updating that sends of receiving mobility managed network element, this tracing section updating accept message carry this UE carrying or the priority attribute determination policy information of the APN that contracts.Be understandable that, mobile management network element is also by other one or more message, to UE transmit its carrying or the priority attribute determination policy information of the APN that contracts, UE then obtains the loading priority attribute determination policy information that mobile management network element transmits from this NAS message, will not enumerate herein.

B2, UE according to the priority attribute determination policy information of its carrying or the institute APN that contracts, determine the business of initiation based on carrying or the priority of APN;

In actual applications, its carrying that UE transmits according to mobile management network element or the priority attribute determination policy information of the APN that contracts, the priority of confirmable one or more carrying or APN.

Such as, if priority attribute determination policy information comprises: the priority attribute instruction of one or more APN that UE contracts, then UE is according to this priority attribute determination policy information, can determine the priority of all carryings that its signing one or more APN are corresponding.Or, if loading priority attribute determination policy information comprises: the priority attribute instruction of one or more carryings that UE sets up, then UE is according to this priority attribute determination policy information, can determine the priority of one or more carryings of foundation.Be appreciated that, the part priority level APN that can comprise UE in priority attribute determination policy information signing (such as comprises height/medium priority APN, or medium/low priority APN) priority attribute instruction, and/or, the part priority level carrying comprising UE foundation (such as comprises height/medium priority carrying, or the carrying of medium/low priority) priority attribute instruction, and the priority attribute not comprising residue priority level APN (such as not comprising low priority APN or high priority APN) or carrying (such as not comprising low priority carrying or high priority carrying) indicates (wherein, UE can be defaulted as this part APN or carrying is certain priority), under this scene, the priority attribute instruction of the part priority level APN (or carrying) that UE can comprise according to priority attribute determination policy information, determine the priority of all APN (or carrying).

For example, current 3 APN (as APN1, APN2 and APN3) of having contracted of UE, wherein, if mobile management network element determines that APN1 is low priority, APN2 is high priority, APN3 is high medium priority, and now, the priority attribute determination policy information that mobile management network element transmits to UE can comprise: instruction APN1 is low priority, APN2 is high priority, APN3 is the priority indication information of high medium priority, or, can comprise that instruction APN2 is high priority, APN3 is the priority indication information of high medium priority, but not comprising instruction APN1 is the priority indication information of low priority, and now, according to this priority attribute determination policy information, UE then can determine that APN2 is high priority, APN3 is high medium priority, and can give tacit consent to and determine that APN1 is low priority (i.e. UE and network side about fix in priority attribute determination policy information the APN not carrying the instruction of respective priority attribute to be defaulted as be low priority attribute), or, the priority attribute determination policy information that mobile management network element transmits to UE can comprise: instruction APN1 is low priority, APN3 is the priority indication information of high medium priority, but not comprising instruction APN2 is the priority indication information of high priority, and now, according to this priority attribute determination policy information, UE then can determine that APN1 is low priority, APN3 is high medium priority, and can give tacit consent to and determine that APN2 is high priority (i.e. UE and network side about fix in priority attribute determination policy information the APN not carrying the instruction of respective priority attribute to be defaulted as be high priority attribute), by that analogy.

Again for example, if the loading priority attribute determination policy information that mobile management network element transmits to UE comprises: the indication information of the spans such as the tolerance of the Qos of the carrying correspondence of various priority level (such as high/medium/low), time delay or packet loss, then the related parameter values of carrying and various priority level can be carried corresponding Qos by UE, time delay tolerates or the span such as packet loss compares, and then can determine the priority of carrying.

Be understandable that, the priority attribute of the APN that UE contracts, can regard the priority attribute of all carryings corresponding to this APN as, that is, when UE determines the priority attribute of its certain signing APN, be also just equivalent to the priority attribute defining all carryings corresponding to this APN.

B3, UE generate switch-in attribute instruction corresponding to the priority determined;

Wherein, switch-in attribute instruction can indicate the priority (such as can indicate access priority grade, time delay tolerance grade, packet loss grade, QoS grade etc.) of access, and being appreciated that access priority is higher then can more priority access.

Wherein, the instruction of this switch-in attribute and the business that the UE determined initiates based on APN or the priority of carrying corresponding.Such as, if determine UE initiate business based on APN or the priority of carrying be high priority, then the access priority grade of switch-in attribute instruction shown in indication that UE generates can be high priority; If determine UE initiate business based on APN or the priority of carrying be medium priority, then the access priority grade of switch-in attribute instruction shown in indication that UE generates also can be middle access priority (or being high/low priority); If the UE that determines initiate business based on APN or the priority of carrying be low priority, then the access priority grade of switch-in attribute instruction shown in indication that UE generates also can be low priority, for the scene having multiple priority level, can be by that analogy.

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

In actual applications, the switch-in attribute instruction that UE generates can be any information that network equipment can be made to determine the access priority grade of business.

Wherein, UE such as can at wireless heterogeneous networks (RRC, Radio Resource Control) carry the instruction of this switch-in attribute, with the switch-in attribute to access network element indicating services in message (as RRC connection request message or RRC have connected message etc.) or other message; And/or, the instruction of this switch-in attribute can be carried in NAS message (such as business request information, Attach Request message or location update request message etc.), with the switch-in attribute to mobile management network element indicating services.

Further, access network element can receive the message (as RRC connection request message or RRC have connected message etc.) of carrying switch-in attribute instruction or other message that UE sends in business initiation process; Access network element can carry out access control according to the instruction of this switch-in attribute to the business that UE initiates.For example, if the access priority grade indicated by the instruction of this switch-in attribute is high access priority, then access network element can this business of priority access, if the access priority grade indicated by the instruction of this switch-in attribute is low access priority, then access network element can be selected refusal access or postpone this business of access etc. when network congestion.

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

Can find out, because mobile management network element passes through NAS message in the present embodiment, by the carrying of UE or the priority attribute determination policy information of the APN that contracts pass to UE, UE can according to this priority attribute determination policy information, determine the business initiated based on carrying or the priority of APN; Generate the switch-in attribute instruction that the priority of the carrying determined is corresponding; And the message of carrying the instruction of this switch-in attribute is sent to network side, making network side can carry out access control according to the instruction of this switch-in attribute to the business that UE initiates becomes possibility.This mechanism make UE its initiation business clear and definite based on carrying priority, UE makes network side can specify its service access control logic by instruction, so be conducive to improving the reasonability that network side process UE initiates business, be conducive to strengthening user to the experience of application-specific.

Below from the angle of access network element, the present invention program is introduced.

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

See Fig. 1-c, concrete steps can comprise:

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

Wherein, access network element can receive the RRC information (as RRC connection request message or RRC have connected message) of carrying switch-in attribute instruction or other message that UE sends in business initiation process.

Be understandable that, UE also can select in the message sent to access network element (or mobile management network element), to carry switch-in attribute indication bit position when high access priority grade, and acquiescence instruction is adopted when low access priority grade, namely when high access priority, UE carries switch-in attribute indication bit position in the message to indicate high access priority grade, and when low access priority, UE does not carry switch-in attribute indication bit position in the message, now access network element (or mobile management network element) is defaulted as UE is the low access priority grade of instruction, or, UE also can select in the message sent to access network element, to carry switch-in attribute indication bit position when low access priority, and acquiescence instruction is adopted when high access priority, namely when high access priority, UE does not carry switch-in attribute indication bit position in the message, now access network element (or mobile management network element) is defaulted as UE is the high access priority of instruction, by that analogy.

It should be noted that, before UE initiates the request of RRC connection establishment to access network element, first can read expansion access rank restriction (Extended Access Class Barring) in cell broadcast messages and access rank restriction (Access Class Barring), and according to expansion access rank restriction and the restriction of access rank, judge whether active wireless network allows the current business that will initiate (may be low priority traffice (business that such as time delay tolerance is high) access, if judge, active wireless network does not allow this service access (may be that access network element current loads is heavier), then can suspend and initiate this business.

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

For example, if the access priority indicated by the instruction of this switch-in attribute is high access priority, then access network element can preferentially access, if the access priority indicated by the instruction of this switch-in attribute is low access priority, then access network element can be selected refusal access or postpone access etc. when network congestion.

Can find out, the APN issued according to mobile management network element due to UE in the present embodiment or the priority attribute determination policy information of carrying, determine the business initiated based on APN or the priority of carrying; And generate switch-in attribute instruction corresponding to the priority determined; Send the message of carrying the instruction of this switch-in attribute to access network element, access network element can carry out access control according to the instruction of this switch-in attribute to the business that UE initiates.This mechanism specify that the service access control logic of access network element, so be conducive to improving the reasonability that access network element process UE initiates business, is conducive to strengthening user to the experience of application-specific.

Embodiment one

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

Mainly for when UE adheres in the present embodiment, network side can according to one or more in the information such as the subscription data of this UE, carrier policy and local policy, determine the priority attribute of one or more carryings of this UE or this UE the priority attribute of one or more APN of contracting, and this priority attribute information is passed to UE, so that UE and access network element (or MME) carry out the access control of this UE business according to this priority attribute information.

Can comprise see Fig. 2, concrete steps:

201, UE sends Attach Request message to MME.

Under a kind of application scenarios, carrying out in network attachment process, UE by RRC information to eNB indicate with the APN of this UE default configuration or carry corresponding access priority (such as can RRC set up request message or RRC set up in message carry switch-in attribute and indicate), or UE indicates with the APN of this UE default configuration by NAS message to MME or carries corresponding access priority (herein can at Attach Request message) etc., wherein, with the APN of this UE default configuration or to carry corresponding access priority may be low priority (as higher in time delay tolerance), high priority (as lower in time delay tolerance), medium priority or other access priority.In addition, if UE do not configure with default configuration APN or carry corresponding access priority, then UE also can not indicate access priority to eNB or MME.

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 the situation needing the priority attribute transmitting one or more carrying to UE, MME can determine the priority attribute of this one or more carrying, and priority attribute comprises such as time delay tolerance, packet loss or QoS etc. or other service attribute.Wherein, MME can according to one or more in the information such as the subscription data of this UE obtained from HSS, corresponding APN, operator's collocation strategy and local policy, determine the priority attribute of this several carrying.

For the situation needing the priority attribute (priority attribute of APN herein also can regard the priority attribute of all carryings corresponding to this APN as) transmitting one or more APN to UE, the upper priority attribute information can preserving each APN that this UE contracts of HSS; For example, current 3 APN (as APN1, APN2 and APN3) of having contracted of UE, wherein, APN1 may be low priority, and APN2 may be high priority, and APN3 may be high medium priority.Which APN is the priority attribute information of each APN that UE contracts such as can indicate be low priority, and which APN is high priority, for the situation having multiple priority level, by that analogy.

Certainly, MME also can determine the priority attribute of some or multiple APN that UE contracts, such as, can determine its time delay tolerance, Qos, packet loss or other service attribute.MME according to one or more in the information such as the subscription data of HSS, corresponding APN, operator's collocation strategy and local policy, can determine the priority attribute of this APN.Be understandable that, MME also can determine that UE contracts the priority attribute of all APN, signing 3 APN (as APN1, APN2 and APN3) of such as UE, MME can according to one or more in the information such as the subscription data of this UE on HSS, operator's collocation strategy and local policy, and determining APN1 is normal priority, and APN2 is low priority, APN3 is high priority, by that analogy, for the situation having multiple priority level, by that analogy.

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

204, gateway device sets up default bearer, and sets up session request response to MME transmission;

Under a kind of application scenarios, if UE carries APN information in above-mentioned Attach Request message, then in step 203 ~ 204, MME initiates to set up gateway (SGW, Serving Gateway) and grouped data network gateway (PGW, Packet Data Network Gateway) about the default bearer of this APN.Otherwise, MME initiates the default bearer setting up the default APN that this UE contracts, wherein, this sets up bearing identification information, the APN information that can carry default bearer in conversation request message, or the priority attribute information etc. of this carrying or APN can also be carried, wherein, this priority attribute information from the instruction of UE, or also can be determined by MME.

In addition, PGW, SGW or PCRF (Policy and Charging Rules Function, strategy and charging rule functions) entity also can according to APN information, one or more in the information such as the carrier policy that this network element configures and local policy, determine the priority attribute information of this carrying or APN, and by setting up conversational response message, this priority attribute information being passed to MME, MME also can obtain the priority attribute information of this carrying or APN accordingly.

Be understandable that, the carrying of UE or the priority attribute of signing APN can be determined by the some nodes (such as MME, PGW, SGW or PCRF entity etc.) in core net, also jointly can be determined by certain several node, wherein, this one or several node can determine jointly according to one or more parameters in the information such as the relevant subscription data of HSS preservation, APN information, carrier policy and local policy.

In addition, APN list information signing for UE, also by setting up conversation request message, is passed to PGW by MME, and this is set up in conversation request message and yet can carry UE and to contract the priority attribute information of APN.

205, the priority attribute information of this APN or carrying is passed to UE by MME;

Wherein, MME receive from gateway device set up session request response after, determine that the default bearer of this APN has been set up, the priority attribute information of this APN or carrying, by NAS message, is passed to UE by MME.For example, MME accepts message by attachment, and the priority attribute information of APN or carrying is passed to UE.

In actual applications, if MME is the priority attribute information (can comprise the priority attribute information of current APN) transmitting APN to UE, such as, MME can increase an attribute indication field in the default EPS bearer context request of activation (ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST) in attachment response message, attribute indication field is utilized to carry the priority attribute information of APN, to be passed to UE.Wherein, this attribute indication field such as can indicate this APN to be low priority (tolerating as indicated high time delay), or, when this APN is not low priority (such as low time delay tolerance), network side also can not carry indication bit in the message, now, it is normal priority or high priority that UE is defaulted as this APN, and operates according to normal mode; Or when this APN is low priority, network side also can not carry indication bit in the message, now, it is low priority that UE is defaulted as this APN, by that analogy.

In addition, MME APN attribute list of also UE can being contracted is carried at attachment response message.The priority attribute indication information of APN list and correspondence thereof can be recorded in this APN attribute list.

For example.UE contracts APN1, APN2 and APN3, and it is that low preferential, APN2 is normal priority, APN3 is high priority that APN attribute list indicates APN1.In addition, also the APN list of low priority (as high time delay is tolerated) attribute can be only included in APN attribute list, or also can only include the APN list of high priority or normal priority attribute in APN attribute list, UE can determine the priority attribute of all signing APN accordingly.

In addition, if MME is the priority attribute information transmitting carrying to UE:

Such as, 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 activation in attachment response message, utilizes this attribute indication field to carry the priority attribute information of carrying, to be passed to UE.Wherein, this attribute indication field such as can be designated as low priority (as high time delay is tolerated), or, when this carrying is not low priority (such as low time delay tolerance), MME can not carry above-mentioned attribute indication field in the message, now, UE is defaulted as this and is carried as normal priority or high priority, and operates according to normal mode.

Again such as, which Qos span network side can define is low priority, and those which Qos spans are high priority etc., and such as defining which QCI is low priority business; Or also can define and be carried as low preferential carrying within the scope of which time delay or packet loss, priority attribute strategy can be passed to UE by MME, UE judges which is carried as low preferential carrying voluntarily, which is carried as high priority carrying, and UE specifically can judge the priority of this carrying according to the Qos of each carrying.

206, UE sends attachment to MME and completes message.

207, follow-up UE is when being converted to connected state by initiating business request from Idle state, or when connected state initiating business request, the business will be able to initiated according to this service request based on APN or the priority of carrying, generation switch-in attribute indicates, and the message of carrying the instruction of this switch-in attribute is sent to network side, be convenient to network equipment like this, according to the instruction of this switch-in attribute, access control carried out to this business that UE initiates.

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

Such as, switch-in attribute instruction is passed to eNB by RRC information (such as RRC sets up request message or RRC has set up message etc.) by UE, and the service access whether eNB can allow this UE to initiate according to the switch-in attribute instruction decision in RRC information.In addition, the instruction of this switch-in attribute, also by NAS message, is passed to MME by UE, to MME indicate this business institute based on APN or the priority of carrying, and the service access whether MME also can allow this UE to initiate according to the switch-in attribute instruction decision in message.

Can find out, because MME is based on the attachment flow of UE in the present embodiment, by attachment accept message by the carrying of UE or the priority attribute determination policy information of the APN that contracts pass to UE, UE can according to this priority attribute determination policy information, determine the business initiated based on carrying or the priority of APN; Generate the switch-in attribute instruction that the priority of the carrying determined is corresponding; And the message of carrying the instruction of this switch-in attribute is sent to network side, make network side can carry out access control according to the instruction of this switch-in attribute to the business that UE initiates.This mechanism make UE its initiation business clear and definite based on carrying priority, UE makes network side can specify its service access control logic by instruction, so be conducive to improving the reasonability that network side process UE initiates business, be conducive to strengthening user to the experience of application-specific.

Embodiment two

Mainly for the priority attribute information not obtaining APN or carrying before UE from network side in the present embodiment, UE first uses default configuration (as high priority or low priority) when the business of initiation or normally accesses, determined the priority attribute of its APN or carrying by network side after access, and pass to this UE, so that UE and access network element (or MME) carry out the access control of this UE business according to this priority attribute information.

See Fig. 3, concrete steps can comprise:

301, UE is registered to network, when needing the PDN setting up certain APN corresponding to connect, UE sends PDN connection request (PDN Connectivity Request) to MME, and when initiating business request, UE can use default configuration (as high/low priority) or access according to normal mode.

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 sets up session request response from gateway device;

Wherein, MME receive from gateway device set up session request response after, determine that the default bearer of this APN has been set up.

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

In addition, PGW, SGW or PCRF entity also can according to APN information, one or more in the information such as the carrier policy that this network element configures and local policy, determine the priority attribute information of this carrying or APN, and by setting up conversational response message, this priority attribute information being passed to MME, MME also can obtain the priority attribute information of this carrying or APN accordingly.

304, the priority attribute information of this APN or carrying is passed to UE by NAS message by MME;

In actual applications, if MME is the priority attribute information (can comprise the priority attribute information of current APN) transmitting APN to UE.Such as, MME can increase attribute indication field in PDN ConnectivityAccept (PDN connects acceptance) message, utilizes attribute indication field to carry the priority attribute information of APN, to be passed to UE.Wherein, this attribute indication field such as can indicate this APN to be low priority (tolerating as indicated high time delay), or, when this APN is not low priority (such as low time delay tolerance), network side also can not carry indication bit in the message, now, it is normal priority or high priority that UE is defaulted as this APN, and operates according to normal mode; Or when this APN is low priority, network side also can not carry indication bit in the message, now, it is low priority that UE is defaulted as this APN, by that analogy.

Such as, MME transmits the priority attribute of current carrying to UE, increase an attribute indication field in the default EPS bearer context request of activation that MME can accept in message at PDN, utilize this attribute indication field to carry the priority attribute information of carrying, to be passed to UE.Wherein, this attribute indication field such as can be designated as low priority (as high time delay is tolerated), or when this carrying is not low priority (such as low time delay tolerance), MME can not carry above-mentioned attribute indication field in the message, now, 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 when being converted to connected state by initiating business request from Idle state, or when connected state initiating business request, the business will be able to initiated according to this service request based on APN or the priority of carrying, generation switch-in attribute indicates, and the message of carrying the instruction of this switch-in attribute is sent to network side, be convenient to network equipment like this, according to the instruction of this switch-in attribute, access control carried out to this business that UE initiates.
