Several specific embodiments can be combined with each other below, for the same or similar content, no longer carry out in various embodiments
Repeated explanation.
Fig. 2 is a kind of schematic diagram of method for improving traffic diversion WLAN success rate provided in an embodiment of the present invention, please be joined
As shown in Figure 2, the method for the raising traffic diversion WLAN success rate may include:
S201, eNB send WT to corresponding WT and add request message.The WLAN that WT is UE is mobile to concentrate all AP corresponding
WT。
WT is with adding the WLAN MAC that request (WT addition request) message includes: eNB UE XwAP ID, UE
The mobile collection of the WLAN of location, the first carrying list and UE.ENB UE XwAP ID is the ID that eNB distributes to UE, in Xw interface
The side eNB identify UE, the WLAN MAC Address of UE UE and receives in the WT association process of WT addition request message for after
UE is identified, the first carrying list is the column for the EPS carrying for needing to redirect to WLAN that eNB is determined in all EPS carrying of UE
Table；WLAN movement integrates as the set of the preferable WLAN AP of UE ambient signals quality, these AP are the AP under same WT control.eNB
The corresponding WT of all AP is concentrated to send WT addition request message to the WLAN of UE is mobile.
For being in the UE of RRC_CONNECTED, if UE indicates that UE supports RCLWI into the ability information that eNB is reported,
ENB can configure WLAN measurement to UE by RRC connection reconfiguration message.UE executes phase according to the WLAN measurement configuration information of eNB
The WLAN measurement answered.When measurement event is triggered or periodic measurement is triggered, UE passes through MeasurementReport message
WLAN measurement result is reported to eNB.The WLAN measurement result that eNB is reported according to UE determines that the mobile collection of the WLAN of UE, the WLAN move
It is dynamic to integrate as the set of the preferable WLAN AP of UE ambient signals quality (AP:Access Point, access point), and these AP are same
AP under one WT control.Later, whenever the WLAN measurement result for receiving UE and reporting, eNB can dynamic update UE WLAN it is mobile
Collection.
When establishing an EPS between UE and EPC (EPC:Evolved Packet Core, the packet-based core networks of evolution)
When (EPS:Evolved Packet System, the grouping system of evolution) carries, EPC can by QOS that the EPS is carried (QoS:
Quality of Service, quality of service) information is sent to eNB.One EPS carrying QOS information include: QCI (QCI:
QoS Class Identifier, QoS class mark), priority, if whether support seize, allow to be preempted, MBR and GBR
Deng.Support that the UE of RCLWI, eNB can be according to UL/DL residue moneys of eating dishes without rice or wine for establishing instruction in EPS carrying and capability reporting
The WLAN measurement result that source situation, the QOS information of each EPS carrying of UE, UE UL/DL channel quality condition, UE are reported recently
Whether and the mobile the last load measure for collecting corresponding WT of WLAN of UE is reported and can be determined: by certain EPS of UE
Business in carrying is transmitted by WLAN.When eNB determines the service distributing in certain EPS carryings by UE to WLAN, to mention
Success rate of the traffic diversion to WLAN is risen, present invention proposition: eNB first sends WT to corresponding WT and adds request message, to turn to
To WLAN business in advance to corresponding WT application radio resource.
The configuration information of each EPS carrying includes: the mark and qos parameter group of EPS carrying in first carrying list.QoS
Parameter group includes QCI and distribution competition priority (Allocation and Retention Priority).For GBR (GBR:
Guaranteed Bit Rate, the bit rate of guarantee) business, qos parameter group further includes GBR QoS information.The GBR QoS
Information is for providing the MBR and GBR of GBR traffic.
S202, WT add the first carrying list and the mobile collection of WLAN in request message according to WT and determine the second carrying list.
When the second carrying list includes at least an EPS carrying, WT sends WT to eNB and adds request confirmation message.When the second carrying
When list does not include any EPS carrying, WT sends WT addition request refuse information to eNB.
It is carried in WT addition request confirmation message: eNB UE XwAP ID, WT UE XwAP ID, the MAC Address of WT, the
Two carrying lists and third carry list.WT UE XwAP ID is the ID that WT distributes to UE, for marking in the side WT of Xw interface
Know UE, the MAC Address of WT identifies WT for after in UE and WT association process, the second carrying list be in the first carrying list
The side WT be successfully assigned with WLAN radio resource EPS carrying list, third carry list be first carrying list in the side WT not
The EPS carrying list of WLAN radio resource can be distributed.Each EPS carrying in third carrying list is carried and fails to distribute WLAN
The reason of resource.
Specifically, WT adds the second carrying in request confirmation (WT ADDITION REQUEST ACKNOWLEDGE) message
The determination method of list and third carrying list is as follows:
For EPS carrying each in the first carrying list, if in the qos parameter group that the carrying carries including GBR
QoS information shows that the EPS is carried as GBR carrying, then WT needs judge whether that enough WLAN can be distributed to EPS carrying
Resource, to ensure the QoS of EPS carrying.If enough WLAN resources can be distributed to EPS carrying, EPS carrying is added
Enter into the second carrying list.If the EPS carrying carry qos parameter group not in do not include GBR QoS information, show the EPS
It is carried as non-GBR carrying.WT, which can judge whether to carry the EPS according to following possible mode, is added to the second carrying list
In.
It, should if WT judgement can provide minimum bit rate to the non-GBR carrying in the first possible mode
EPS carrying is added in the second carrying list.Wherein, the value of minimum bit rate is configured by WT, in setting minimum bit
When the value of rate, different minimum bit rates can be configured to the non-GBR carrying of different priorities, can also given all non-
GBR carrying configures the same minimum bit rate.Minimum bit rate is used to guarantee the minimum acceptable business of non-GBR carrying
It experiences (Quality of Experience, QoE).
In second of possible mode, according to the EPS carrying distribution competition priority, the remaining WLAN resource of WT with
And pass through the qos parameter group of the business of WLAN transmission, it is determined whether support EPS carrying redirecting to WLAN.Such as: it should
EPS carrying is supported to seize and the priority of EPS carrying is higher than each business for having supported of WT, and these industry for having supported
Business is all supported to be preempted, then can carry the EPS and be added in the second carrying list.
The embodiment of the present invention is only illustrated in above two possible mode as an example, it is of course also possible to pass through other
Possible method is judged, here, for which mode specifically used, the embodiment of the present invention is not particularly limited.
The second carrying list has been determined by the above process, has failed to be included in the second carrying list in the first carrying list
EPS carrying constitutes third and carries list.Each EPS carrying in third carrying list is needed to carry and fails to distribute WLAN resource
The reason of.
When the radio resource of the side WT can not support the EPS carrying in any one first carrying list to turn to WLAN, WT
Feed back WT addition request refusal (WT ADDITION REQUEST REJECT) message.The message carries: eNB UE XwAP ID
And cause value.
S203, request confirmation message is added when eNB receives WT, eNB sends RRC connection reconfiguration message to UE.When eNB connects
Receive WT addition request refuse information, eNB still to UE send RRC connection reconfiguration message, alternatively, eNB certain interval of time it
Return step S201 afterwards.
When eNB receives WT addition request refuse information, then eNB can stop the traffic diversion of UE to WLAN, interval
After one section of duration, return step S201 sends WT to corresponding WT again by step S201 and adds request message, with determination
The traffic diversion whether WT has enough Internet resources to support UE at this time.
Certainly, when eNB receives addition request refuse information, if UL/DL surplus resources of currently eating dishes without rice or wine are very limited, or work as
Preceding UE several EPS carrying support be preempted, and eNB determine seize these EPS carrying resource to other carrying in use,
ENB can also send RRC connection reconfiguration message to UE, and related service is turned to WLAN by mandatum alterius UE.
It is carried in RRC connection reconfiguration message: traffic diversion order traffic steering command.The order packet
It includes: turning to instruction, the mobile collection of WLAN, the MAC Address of WT and the 4th carrying list of WLAN.It is asked when eNB receives WT addition
When seeking confirmation message, the 4th carrying list is the second carrying list；When eNB receives WT addition request refuse information, the 4th
Carry the subset that list is the first carrying list or the first carrying list.
S204, UE save traffic diversion order in RRC connection reconfiguration message, and send the completion of RRC connection reconfiguration to eNB and disappear
Breath.
UE saves the traffic diversion order in message: turning to the finger of WLAN after receiving RRC connection reconfiguration message
Show, the mobile collection of WLAN, the MAC Address of WT and the 4th carrying list, and sends RRC connection reconfiguration to eNB and complete message to show
This RRC connection reconfiguration is completed.
S205, UE attempt to establish connection with the mobile AP concentrated of WLAN according to the traffic diversion order of preservation.If UE is saved
Traffic diversion order in carry " MAC Address of WT ", UE and AP is established after connection, according to the MAC Address of the WT
It is associated with corresponding WT.
Specifically, UE starts WLAN status monitoring process according to the traffic diversion order of preservation.In WLAN status monitoring mistake
Cheng Zhong, UE select a WLAN AP to initiate the connection foundation request in mobile concentrate of WLAN.When cannot connect to the AP, selection
Another AP initiates the connection foundation request, until being successfully connected to a WLAN AP, later, can pass through the WLAN AP again
It is associated with WT foundation.
It should be noted that in embodiments of the present invention, if UE can not be with mobile times concentrated of WLAN in this step S205
When what AP connection, UE can request continue through the business that LTE transmission correlation needs turn to, detailed process to eNB are as follows:
UE sends WLAN Connection Stutus Report message to eNB, instruction: WLAN connection failure.
After eNB receives the instruction of the WLAN connection failure of UE transmission, RRC connection reconfiguration message is sent to UE, in message
Carry traffic steering command.The order includes: to turn to the instruction of LTE.
After UE receives RRC connection reconfiguration message, according to the instruction of the steering LTE of carrying, for that can not be transmitted by WLAN
Business by eNB to EPC apply establish EPS carrying, then by establish EPS carrying transmits corresponding service.When the industry having
Business had built up EPS carrying, not yet discharged, and UE directly restores the carrying, and is carried through LTE transmission business by this.
S206, after UE is associated with WT, WT to eNB send WT be associated with confirmation message.
Above-mentioned WT association confirmation (WT ASSOCIATION CONFIRMATION) message includes WT UE XwAP ID and eNB
UE XwAP ID, the two ID are respectively the ID that WT and eNB are distributed to UE, for being somebody's turn to do in the side WT of Xw interface and the side eNB mark
UE。
After WT and UE foundation be associated withs, send WT association confirmation message to eNB so that eNB receive the confirmation message it
Afterwards, according to WT UE XwAP ID and eNB UE XwAP ID determination and the associated UE of corresponding WT.
After S207, UE are associated with WT, UE sends WLAN connection state reporting message to eNB.
Wherein, it carries in WLAN connection state reporting (WLAN Connection Stutus Report) message: successfully closing
Connection instruction, the instruction are used to indicate UE and have been successfully connected to WLAN.
It determines that WT has been established with UE by above-mentioned S206 and S207, eNB to be associated with, later, UE can transmit industry by WLAN
The business being engaged in diversion order in the 4th carrying list in each EPS carrying, therefore, eNB can discharge the 4th at this time earliest
The occupied side LTE resource before each EPS carrying in carrying list.Certainly, eNB can also discharge in following step S210
The LTE resource that respective carrier occupies.
It should be noted that in embodiments of the present invention, the executing subject of S206 and S207 is different, between S206 and S207
Sequencing is had no, S206 can be first carried out, S207 can also be first carried out, it is of course also possible to it is performed simultaneously S206 and S207,
This, the embodiment of the present invention is only to first carry out S206, then executes and be illustrated for S207, but does not represent and of the invention only limit to
In this.
