Wherein, the precedence information of UE may be embodied in the subscription data of UE, and be sent to MME by HSS.It is exemplary , the precedence information of UE can be it is high or low, when the priority for including in the subscription data that MME receives the UE of HSS transmission When information is low, it can determine that the UE is the UE for needing SGW to page.

Alternatively, the precedence information of UE can be sent to MME by UE.Illustratively, the precedence information of UE can be height Or it is low, when the precedence information that MME receives UE transmission is low, it can determine that the UE is the UE for needing SGW to page.

It should be noted that the present invention only by the precedence information of UE be it is high or low for illustrate, certainly, UE's is preferential Grade information may be 1 grade, 2 grades ... n grades, and the present invention is not intended to limit the representation of precedence information herein.Likewise, excellent First grade information is that low UE can be the UE for needing SGW to page, and certainly, precedence information is that high UE may be that SGW is needed to page UE, the present invention herein only explanation in a certain priority UE can be need SGW page UE, being not intended to limit needs SGW to seek The specific priority of the UE exhaled, that is to say, that the present invention is that declaratives UE can be paged by SGW.

Mode three: MME receives the paging indication information for the UE that HSS is sent, and determines UE according to the paging indication information of UE For the UE for needing SGW to page.

Wherein, paging indication information is used to indicate whether UE is paged by SGW, and the paging indication information of UE may include MME is sent in the subscription data of UE, and by HSS.Illustratively, the paging indication information can for paged by SGW, It is paged by MME, when the paging indication information that MME receives HSS transmission is to be paged by SGW, can determine the UE For the UE for needing SGW to page.

The first information of S502, MME acquisition UE.

Wherein, the first information pages UE for SGW.The first information may include at least one of: instruction by Registration information of the SGW to the UE instruction information or UE paged.Wherein, the registration information of UE may include the interim of UE Mark, CSG identification list, the UE of the tracking zone list of UE, the eNodeB address list of UE, the paging cycle of UE, UE are nearest Once the resident address eNodeB, UE the last time resident eNodeB mark, UE the last time resident tracing area and The cell ID that UE the last time is resident is any one or more of.

Illustratively, the process that MME obtains the first information of UE can be with are as follows: MME can in UE interactive process, by it Its network element is sent to MME, is also possible to be UE distribution by MME.For example, the interim mark for the UE for including in the first information of UE It is that UE is distributed that knowledge, which is by MME, and the resident cell ID of the UE last time for including in the first information of UE is that MME is handed over UE During mutually, it is reported to MME's by eNodeB.

S503, MME send the first information of UE to SGW.

Wherein, determining that UE is the UE for needing SGW to page, and after getting the first information of UE, MME can be to The first information of SGW transmission UE.

Optionally, the first information can be carried and be sent to SGW in releasing wireless loading request message by MME.Certainly, One information can also be carried in MME into other message that SGW is sent, and the embodiment of the present invention is herein with no restrictions.

S504, SGW receive the first information that MME is sent.

Wherein, after the first information for receiving MME transmission, SGW can be saved the first information.

It should be noted that paging method provided in an embodiment of the present invention can repeat S501-S504, in this way, SGW In can save the first information of multiple UE.Certainly, paging method provided in an embodiment of the present invention can also without carrying out S501, But repeating S502-S504, i.e. MME can not have to determine the UE for needing SGW to page, but by all UE's of self-management The first information is sent to SGW, to save the first information for all UE that MME is managed in SGW.

S505, SGW receive the downlink data for the UE that PGW is sent.

Wherein, in downlink data comprising SGW be UE distribution Tunnel Identifier (English: Tunnel Identity, referred to as: TEID) and Internet protocol (English: Internet Protocol, referred to as: IP) address, downlink data can be downlink signaling Or downlink user face data is wrapped in the downlink data when the downlink data that SGW receives the UE that PGW is sent is downlink signaling It is the control plane TEID and IP address of UE distribution containing SGW；When the downlink data that SGW receives the UE that PGW is sent is downlink user face It include the user face TEID and IP address that SGW is UE distribution when data, in the downlink data.

S506, SGW determine that UE is in Idle state according to the downlink user face information that eNodeB is that UE is distributed.

Wherein, downlink user face information is downlink user face TEID and IP address.Illustratively, if SGW detect from There is no downlink user face TEID and IP address that eNodeB is UE distribution in the context for the UE that body saves, it is determined that UE is in Idle state.Certainly, SGW can also determine that UE is in Idle state by other means, for example, if SGW detects what itself was saved ENodeB in the context of UE is the downlink user face TEID of UE distribution and the label of IP address is, it is determined that UE is in Idle state.The embodiment of the present invention determines that UE is in the mode of Idle state with no restrictions to SGW at this.

The downlink data of the UE of PGW transmission is received in SGW, and after determining that the UE is in Idle state, just triggering is sought Exhale process.Specifically, in one possible implementation, as shown in fig. 7, if SGW is determined according to the downlink data received It itself is stored with the first information of the UE, then executes S507-S508, if SGW determines itself not according to the downlink data received It is stored with the first information of the UE, then downlink data notification message is sent to MME, so that MME pages the UE.Another In kind possible implementation, as shown in figure 8, if SGW is determined according to the downlink data received itself is stored with the of the UE One information, then execute S508, if SGW determines itself not stored first information for having the UE according to the downlink data received, Downlink data notification message is sent to MME, so that MME pages the UE.

Wherein, SGW can be that each UE of its management distributes corresponding TEID and IP address in advance, and by the TEID of distribution It is stored with IP address, and after receiving the first information of some UE of MME transmission, SGW can be by the first letter of the UE Breath carries out corresponding storage.In this way, in the downlink data for the UE for receiving PGW transmission, and after determining that the UE is in Idle state, SGW can determine the TEID and IP whether being stored in SGW with UE according to the TEID and IP address for the UE for including in downlink data The first information of the corresponding UE in address.

S507, SGW determine that the attribute of downlink data meets predetermined condition.

Wherein, attribute may include ARP, type of service and DSCP.

When downlink data is downlink signaling, if the attribute of downlink signaling meets any one of the following conditions, SGW is true The attribute for determining downlink signaling meets predetermined condition.

Condition 1: the ARP value carried belonging to downlink signaling is less than preset threshold.

Condition 2: the ARP value of the associated default bearer of downlink signaling is less than preset threshold.

Wherein, preset threshold can be pre-configured on SGW.

When downlink data is downlink user face data, in one possible implementation, if downlink user face data The ARP value of affiliated carrying is less than preset threshold, then SGW determines that the attribute of downlink user face data meets predetermined condition.Another It is preconfigured with itself if the type of service that downlink user face data includes indicates or DSCP in the possible implementation of kind Strategy matches, then SGW determines that the attribute of downlink user face data meets predetermined condition.For example, the preconfigured strategy of SGW can Think that non-voice service is paged by itself, voice service is paged by MME, in this way, working as the downlink user that SGW is received When the type of service that face data includes is non-voice service, since the type of service that the downlink user face data includes is pre- with itself The strategy first configured matches, it is determined that the attribute of downlink user face data meets predetermined condition.

It should be noted that the embodiment of the present invention is so that type of service is voice service and non-voice service as an example herein It is illustrated, is not limiting as the concrete form of type of service, corresponding business can be selected according to the demand of practical application scene Type.Meanwhile the embodiment of the present invention is also not limiting as the particular content of preconfigured strategy in SGW herein, it can also basis The demand of practical application scene is configured accordingly.

When the attribute of the determining downlink data received of SGW meets predetermined condition, S508 can be executed, when SGW is determined When the attribute of the downlink data received is unsatisfactory for predetermined condition, downlink data notification message can be sent to MME, so as to MME The UE is paged.

Due to the type of service that SGW can be used for the priority or UE of the downlink data of UE, determination is sought accordingly Exhale strategy (paging policy are as follows: paging is carried out to UE by SGW or is paged by MME to UE).Specifically, due to MME On be stored with more paging policy data, the paging of greater efficiency can be executed, it is ensured that Quick Paging to UE, Jin Erwei UE provides service, and the business of low priority does not specially require service quality, therefore, for using high-priority service UE can be paged by MME, for using the UE of low priority traffice that can be paged by SGW.Pass through the above differentiation Paging policy not only reduces the paging load of MME, allows MME to provide service for more UE, and fully consider The type of service that UE is used, guaranteeing can by Quick Paging, to ensure that user experience using the UE of high-priority service.

S508, SGW send paging message to eNodeB according to the first information.

Wherein, in one possible implementation, when the first information includes the instruction for indicating to page UE by SGW When information, S508 specifically can be with are as follows: paging message is sent to eNodeB according to the IMSI generating beep-page message of UE by SGW.

Wherein, the IMSI of UE is stored in SGW, which can be in the process that MME notifies SGW to establish session, by MME It is sent to SGW.It include the IMSI of UE in the paging message.

In alternatively possible implementation, when the first information includes the registration information of UE, S508 specifically can be with Are as follows: paging message is sent to eNodeB according to the registration information generating beep-page message of UE by SGW.

Wherein, in paging message comprising the temporary identifier of UE, the tracking zone list of UE, the paging cycle of UE, UE CSG One of resident cell ID of the tracing area and UE the last time that identification list, UE the last time are resident is a variety of.

Since paging message cannot be sent between eNodeB and SGW in the prior art, in order to make eNodeB and SGW it Between can send paging message, need to provide identical agreement between eNodeB and SGW, so as to eNodeB can identify SGW send out Any one agreement in GTP-U, GTP-C and SCTP optionally, between eNodeB and SGW can be used in the paging message sent Paging message is sent, when using GTP-U between eNodeB and SGW, SGW can use sending method one, send to eNodeB Paging message, when using GTP-C between eNodeB and SGW, SGW can use sending method two, send and page to eNodeB Message, when using SCTP between eNodeB and SGW, SGW can use sending method three, send paging message to eNodeB, Wherein, sending method one, sending method two and sending method three are described in detail below.

Paging message is packaged by sending method one: SGW according to S1-AP, and by the paging message after encapsulation include ENodeB is sent in GTP-U data packet.

Wherein, comprising for determining that the message that the GTP-U data packet includes is paging message in GTP-U data packet head TEID.For example, it is used to determine that the value that the message that the GTP-U data packet includes is the TEID of paging message is 1001, when ENodeB receive SGW transmission GTP-U data packet when, judge the TEID for including in the GTP-U data packet head value whether It is 1001, if so, determining that the message for including is paging message, at this point, the GTP-U can be read in the GTP-U data packet The paging message for including in data packet, and the paging message is sent to UE.

It should be noted that the present invention is to for determining the message that the GTP-U data packet includes for the TEID of paging message Value with no restrictions, corresponding value can be arranged according to the demand of practical application scene.

Paging message is included being sent to eNodeB in GTP-C message by sending method two: SGW.

Wherein, comprising for determining the message that the GTP-C data packet includes for the mark of paging message in GTP-C message header (English: Identity, referred to as: ID).For example, for determining that the message for including in the GTP-C message is the ID of paging message Value is 1010, when eNodeB receives the GTP-C message of SGW transmission, judges taking for the ID for including in the GTP-C message header Whether value is 1010, if so, determining that the message for including in the GTP-C message is paging message, at this point, this can be read The paging message for including in GTP-C message, and the paging message is sent to UE.

It should be noted that the present invention is to for determining that message that the GTP-C message includes is taking for the ID of paging message With no restrictions, corresponding value can be arranged according to the demand of practical application scene in value.

Paging message is packaged by sending method three: SGW according to S1-AP, and by the paging message after encapsulation include ENodeB is sent in SCTP data packet.

When SGW sends paging message to eNodeB using sending method one or sending method two, since SGW is in sender The GTP-U that is used in formula one and in sending method two using GTP-C be all no confirmation message, in order to guarantee message transmission Reliability, after sending paging message to eNodeB, SGW starts timer, does not receive before timer stops when determining When the bearing modification request for the UE that MME is sent, paging message is retransmitted to eNodeB, and restart timer, Zhi Daojie After the bearing modification request for receiving UE, stop timer.

When SGW sends paging message using sending method three-dimensional eNodeB, although what SGW was used in sending method three SCTP itself has an affirmation mechanism, but paging message be by that may have loss when eating dishes without rice or wine to send, in order into One step guarantees the reliability of message transmission, and optionally, SGW also can star timer, does not connect before timer stops when determining When receiving the bearing modification request of the UE of MME transmission, paging message is retransmitted to eNodeB, and restart timer, directly To after the bearing modification request for receiving UE, stop timer.

Optionally, SGW can send page notification message to MME.

Wherein, page notification message is for notifying MME to be paged by SGW to UE.When MME receives seeking for SGW transmission When exhaling notification message, MME, which can be determined, pages UE by SGW, that is to say, that itself does not need to seek UE It exhales.The notification message can be downlink data notification message, or other message, or the message newly defined, The present invention at this to the specific format of the notification message with no restrictions.

In order to shorten the duration of SGW paging UE, in a kind of optional embodiment, in S504, when SGW receives MME When the first information of transmission includes the eNodeB address list of UE, S508 specifically can be with are as follows: SGW according to the first information in include UE eNodeB address list, each eNodeB into eNodeB address list sends paging message.

It include UE's when SGW receives the first information that MME is sent in S504 in another optional embodiment Tracking zone list, when not including the eNodeB address list of UE, S508 specifically can be with are as follows: SGW according to the first information in packet The tracking zone list of the UE contained obtains the ground that corresponding eNodeB is identified with each tracing area in tracking zone list Location, so that the eNodeB address list of UE is obtained, further according to the eNodeB address list of obtained UE, to the address eNodeB Each eNodeB in list sends paging message.

It wherein, include the tracking zone list of UE in the paging message, in this way, receiving seeking for SGW transmission in eNodeB After exhaling message, paging message only is sent to UE in the cell that tracking zone list includes.

Wherein, SGW according to the first information in include UE tracking zone list, obtain with it is every in tracking zone list The mode that a tracing area identifies the address of corresponding eNodeB can be any one of the following manners:

ENodeB corresponding with each tracing area mark in tracking zone list is previously stored in mode one: SGW Address.

Wherein, SGW can directly according to the first information in include UE tracking zone list, obtain with tracing area arrange Each tracing area in table identifies the address of corresponding eNodeB.

Mode two: identifying for each tracing area in tracking zone list, and SGW is (English: Domain to domain name system Name service, referred to as: DNS) tracking area identification is sent, so that DNS is obtained and tracking area identification pair according to tracking area identification The address of the eNodeB answered, and the address for the eNodeB that will acquire is sent to SGW, at this point, SGW can receive DNS transmission ENodeB corresponding with tracking area identification address.

Wherein, it is previously stored in DNS and identifies corresponding eNodeB's with each tracing area in tracking zone list Address.

In order to save the power consumption of UE, further, when being previously stored with the paging cycle of UE in MME, in S504 In, SGW, which receives the first information that MME is sent, may include the paging cycle of UE, at this point, SGW disappears to the paging that eNodeB is sent Breath include UE paging cycle, in this way, eNodeB receive SGW transmission paging message after, only in paging cycle to UE sends paging message.

In order to reduce load of eating dishes without rice or wine, further, when being previously stored with the CSG identification list of UE in MME, in S504 In, SGW receives the CSG identification list that may include UE in the first information that MME is sent, at this point, SGW is sought to what eNodeB was sent Exhale message to may include the CSG identification list of UE, in this way, eNodeB receive SGW transmission paging message after, only with CSG in CSG identification list, which is identified in matched cell, sends paging message to UE.Wherein, eNodeB can be multiple cells Service is provided.
