Data communication between LTE network thoroughly disconnects.
Fig. 4 A are refer to, it illustrates the LTE network data closing that an illustrative embodiment of the invention is provided
The flow chart of method.The present embodiment applies to LTE network data method for closing as shown in Figure 1 in this way
Come in UE 120 in involved implementation environment for example, the method includes following steps：
Step 401, receives the out code for indicating to close LTE network data service.
Generally, UE just establishes default bearing once starting shooting with LTE network.That is, PDN connects
Adapter reason process is closely related with default bearing management process, belongs to EPS session managements (English：EPS
Session Management, ESM) process, but generally with EPS Mobility Management (English：EPS
Mobility management, EMM) attaching process accompany, that is to say, that in UE to LTE nets
Network can initiate PDN requests while sending attach request, when the attachment that LTE network receives UE transmissions please
After asking, default bearing can be simultaneously activated.
When user close LTE network operation, UE can receive instruction and close LTE network data service
Out code, and ask with LTE network in PDN-GW disconnect PDN.
This step can call receiver module to realize by the processor in UE.
Step 402, deactivates to the PDN between UE and LTE network, and the PDN is used to transmit this
Network packet between UE and the LTE network.
After the PDN that PDN-GW receives UE disconnects request, can be all by what is be associated with the PDN
Dedicated bearer is all discharged, and initiates load bearing deactivation process.
It should be noted that the PDN said in the present embodiment is the net between transmission UE and LTE network
The PDN of network packet.
This step can call performing module to realize by the processor in UE.
Refer to Fig. 4 B, UE and the LTE network provided it illustrates an illustrative embodiment of the invention it
Between PDN carry out the flow chart of anti-activating method.The present embodiment applies to LTE as shown in Figure 1 in this way
Illustrated in UE 120 in implementation environment involved by network data method for closing.
Optionally, step 402 may alternatively be：
Step 402a, detects whether there is the PDN for receiving data service.
Close the PDN for receiving data service without authorization in order to avoid UE, reduce Consumer's Experience, UE can be with
First detect whether there is the PDN for receiving data service, and preferentially deactivate current not received data business
PDN.
This step can call performing module to realize by the processor in UE.
Step 402b, if in the presence of the PDN for receiving data service, exporting prompting message, prompting letter
Cease for reminding whether user continues to close the data service of LTE network.
If UE detects the PDN for receiving data service, before the PDN is deactivated, can export
Prompting message, the data service for continuing to close LTE network is decided whether by user.
This step can call performing module to realize by the processor in UE.
Step 402c, after the confirmation instruction for receiving the data service for continuing to close LTE network, then performs
The step of PDN between this couple of UE and LTE network is deactivated.
After the confirmation that UE receives the data service for continuing to close LTE network is instructed, illustrate that user determines
Deactivation is receiving the PDN of data service, and UE will be continued executing between deactivation UE and LTE network
The operation of PDN.
This step can call performing module to realize by the processor in UE.
Step 403, in the PDN that only residue one is not deactivated, forbids the PDN to transmit data.
In the lte networks, it is allowed to which a UE connects multiple packet data gateway (English simultaneously：Packet Data
Network Gateway, PDN-GW), so also just generate UE and individually initiate PDN disconnection requests
Application scenarios, but UE must assure that at least one PDN is connected with PDN-GW, otherwise LTE network
The PDN that UE will be refused disconnects request.
This step can call performing module to realize by the processor in UE.
Fig. 4 C are refer to, data are transmitted it illustrates the PDN that forbids that an illustrative embodiment of the invention is provided
The flow chart of method.The present embodiment applies to LTE network data method for closing as shown in Figure 1 in this way
Illustrated in UE 120 in involved implementation environment.
Optionally, step 403 may alternatively be：
Step 403a, UE is connected in non-LTE network, and the non-LTE network is GSM network or UMTS
Network.
In the lte networks, UE must assure that at least one PDN is connected with PDN-GW, otherwise LTE
The PDN that network will refuse UE disconnects request, but in GSM network and UMTS network, UE can break
Open all PDN being connected with PDN-GW, therefore during UE is to disconnect last with LTE network
PDN-GW connection PDN, it is necessary to first by the PDN be connected to non-LTE network (such as GSM network or
UMTS network) on.
This step can call performing module to realize by the processor in UE.
Fig. 4 D are refer to, UE is connected to non-LTE it illustrates what an illustrative embodiment of the invention was provided
The flow chart of method on network.The present embodiment applies to LTE network data as shown in Figure 1 and closes in this way
Illustrated in the UE 120 closed in the implementation environment involved by method.
Optionally, step 403a may alternatively be：
Step 403a1, control UE is forced away from LTE network, and PDN is deactivated, or, control
Make the attachment removal operation of the UE attachment removal LTE networks.
If UE will disconnect last PDN being connected with PDN-GW in LTE network, two kinds can be used
Mode：One is the detachment process for controlling UE to initiate EMM, and two is the LTE for controlling UE to be connected at present
Network switching is to non-LTE network.
In the second way, different from LTE network, in GSM network and UMTS network, UE can
To disconnect all PDN being connected with PDN-GW, therefore as UE successes and non-LTE network (such as GSM
Network, UMTS network) connection after, it is possible to last PDN is deactivated so that the PDN
Disconnection, realize the thorough disconnection of the data communication between UE and LTE network.
This step can call performing module to realize by the processor in UE.
Step 403a2, searches net to non-LTE network, or, forcing gravity treatment to non-LTE network.
Non- LTE network mentioned here typically refers to UE can be disconnected and PDN-GW in the non-LTE network
The network of all PDN of connection, such as GSM network, UMTS network etc..
Net of searching mentioned here refers to that UE is not surveying measured public land mobile network (Public Land
Mobile Network, PLMN) network selection is carried out in list, but directly available network is searched
Rope, and gravity treatment refers to UE carries out network selection in measured PLMN lists have been surveyed.
Together with network selection, cell selection are closely connected with attaching process.UE wants acquisition network and carries
The service of confession, must just select a network, reside in a suitable cell, and successfully completes and adhered to
Journey.Wherein network selection can have automatically and manually two ways, and cell selection, attachment are typically by agreement
What stack was automatically performed.
This step can call performing module to realize by the processor in UE.
Step 403a3, forbids non-LTE network gravity treatment to LTE network.
Fig. 4 E are refer to, it illustrates the LTE network data closing that an illustrative embodiment of the invention is provided
When UE between each physical layer interaction schematic diagram.As a example by searching net, after UE attachment removal LTE networks,
NAS layers sends the order for forbidding gravity treatment LTE network to AS layers in advance, after AS layers receives the order, will
Search for available GSM network and UMTS network, perform to available GSM network and UMTS network
Measurement of correlation, and be synchronized to cell, broadcast received to recognize network ID, while available to NAS layers of report
GSM network and UMTS network, after NAS receives AS layers of report, first safeguard PLMN lists,
And to upper strata report by the AS layers of available GSM network for providing and UMTS network, then automatically or by user
An available GSM network or UMTS network are manually selected, final order AS layer choosings are selected one and belong to institute
The cell of the network of selection provides service.
This step can call performing module to realize by the processor in UE.
In sum, LTE network data method for closing provided in an embodiment of the present invention, by deactivating UE
PDN between LTE network only retains a PDN, and forbids the PDN to transmit data so that UE
Data communication between LTE network thoroughly disconnects.
Optionally, in other alternative embodiments based on Fig. 4 D, when control UE is frequent in user's short time
During switchback LTE network, UE will re-establish PDN with LTE network repeatedly, but this set up PDN's
Process needs to expend certain time length, waits UE to set up PDN's with LTE network to reduce user as far as possible
Duration, improve Consumer's Experience, in predefined conditions UE can tune up before the UE leaves LTE network etc.
Duration is treated, when being easy to the UE to switch back into LTE network in a short time, directly can be connected with LTE network,
Then the embodiment comprises the following steps 403a1a to step 403a1b and step 403a2, refer to Fig. 4 F,
The control UE provided it illustrates an illustrative embodiment of the invention is forced away from LTE network, to PDN
Deactivated, or, control the flow chart of the attachment removal operating method of the UE attachment removal LTE networks.
Step 403a1a, starts first kind timer.
This step can call performing module to realize by the processor in UE.
Step 403a1b, if not receiving unlatching LTE network data in the timing length of first kind timer
The open command of business, then after the timing length in the first kind timer terminates, perform control UE pressures
Leave LTE network, PDN deactivated, or, control the UE attachment removal LTE networks go it is attached
The step of operation.
The timing length of first timer mentioned here refers to the waiting time before UE leaves LTE network.
After UE deactivates the PDN between the UE and LTE network, start first kind timer, if UE
The open command for opening LTE network data service is not received in the timing length of first kind timer, is said
Bright user is not intended to control UE switchback LTE networks in the timing length of first kind timer, now UE
Implementation steps 403a1 can be continued.
If UE receives the unlatching for opening LTE network data service in the timing length of first kind timer
Instruction, illustrates that user intends to control UE switchback LTE networks in the timing length of first kind timer, this
When UE by the PDN between holding and LTE network, no longer implement subsequent step.
This step can call performing module to realize by the processor in UE.
After step 403a1a is implemented, can after step 403a2 implementation steps 403a4, wherein step
403a4 and step 403a3 is limited without implementation order.
Step 403a4, starts Equations of The Second Kind timer, if being received in the timing length of the Equations of The Second Kind timer
Open command, then tune up the timing length of first kind timer according to pre-defined rule.
This step can call performing module to realize by the processor in UE.
Referring also to Fig. 4 E, after UE is connected with non-LTE network, start Equations of The Second Kind timer, if second
In the timing length of class timer, UE receives the open command for indicating to open LTE network data service, says
Bright user has the trend of multiple switchback LTE network, and now UE will tune up the first kind regularly according to pre-defined rule
The timing length of device, i.e., gradually tune up the waiting time before UE leaves LTE network.
Optionally, pre-defined rule can be the timing length by the cumulative first kind timer of scheduled duration.Such as：
If UE receives open command in the timing length of Equations of The Second Kind timer, by the timing of first kind timer
Duration is tuned up 5 seconds.
Optionally, pre-defined rule can also be that unlatching is received in the timing length of Equations of The Second Kind timer by UE
The number of times of instruction, is gradually incremented by scheduled duration, the timing length of the first kind that adds up timer.Such as：If UE
Open command is received in the timing length of Equations of The Second Kind timer for the first time, then determining first kind timer
Shi Shichang is tuned up 5 seconds, if UE receives open command second in the timing length of Equations of The Second Kind timer,
The timing length of first kind timer is then tuned up 10 seconds, by that analogy.
Optionally, pre-defined rule can also be and unlatching is received in the timing length of Equations of The Second Kind timer by UE
Duration size between the moment of instruction and the start-up time of Equations of The Second Kind timer is selected the first kind regularly
The timing length of device tunes up how many.Such as：Equations of The Second Kind timer timing length is 10 seconds, if UE is second
Class timer receives open command in 2 seconds after opening, then tune up the timing length of first kind timer 2 seconds,
If UE receives open command in 5 seconds after the unlatching of Equations of The Second Kind timer, during by the timing of first kind timer
Length is tuned up 5 seconds.
The present embodiment has been only exemplified by several possible pre-defined rule forms, but when actually realizing, pre-defined rule
Form not limited to this.
It should be noted that the present embodiment timing length not to first kind timer, Equations of The Second Kind timer
The specific set-up mode and size of the duration involved by timing length and pre-defined rule are specifically limited.
In sum, LTE network data method for closing provided in an embodiment of the present invention, by predetermined condition
Under tune up the timing length of first kind timer, extension UE leaves the duration of LTE network so that UE is short
When switching back into LTE network in the time, can be directly connected with LTE network, reduce user and wait UE and LTE
