Referring to FIG. 3, the stream of the LTE network data method for closing provided it illustrates an illustrative embodiment of the invention Cheng Tu.Come in the UE 120 that the present embodiment is used in this way in implementation environment shown in FIG. 1 for example, by as shown in Figure 2 UE 120 processor 21 execute following step, this method including the following steps:

Step 301, the out code that LTE network data service is closed in instruction is received.

Step 302, the PDN between UE and LTE network is deactivated, which is used for transmission the UE and the LTE network Between network packet.

Step 303, in only remaining one PDN not being deactivated, the PDN is forbidden to transmit data.

In conclusion LTE network data method for closing provided in an embodiment of the present invention, by deactivating UE and LTE network Between PDN, only retain a PDN, and forbid the PDN transmit data so that the data communication between UE and LTE network is thorough It disconnects.

Fig. 4 A is please referred to, it illustrates the LTE network data method for closing of an illustrative embodiment of the invention offer Flow chart.The present embodiment applies in this way in implementation environment involved in LTE network data method for closing as shown in Figure 1 UE 120 in come for example, this method including the following steps:

Step 401, the out code that LTE network data service is closed in instruction is received.

In general, UE just establishes default bearing with LTE network once being switched on.That is, PDN connection management process with Default bearing management process is closely related, and belongs to EPS session management (English: EPS Session Management, ESM) Process, but the attaching process usually with EPS Mobility Management (English: EPS mobility management, EMM) accompanies, That is, PDN request can be initiated while UE sends attach request to LTE network, when LTE network receives UE transmission After attach request, default bearing can be activated simultaneously.

When user carries out closing LTE network operation, the closing that UE can receive instruction closing LTE network data service refers to It enables, and requests to disconnect PDN with the PDN-GW in LTE network.

This step can call receiving module to realize by the processor in UE.

Step 402, the PDN between UE and LTE network is deactivated, which is used for transmission the UE and the LTE network Between network packet.

After the PDN that PDN-GW receives UE disconnects request, all dedicated bearers associated with the PDN can all be discharged Fall, initiates load bearing deactivation process.

It should be noted that the PDN said in the present embodiment is the network packet transmitted between UE and LTE network PDN。

This step can call execution module to realize by the processor in UE.

Please refer to Fig. 4 B, it illustrates an illustrative embodiment of the invention provide UE and LTE network between PDN into The flow chart of row anti-activating method.The present embodiment applies in this way involved by LTE network data method for closing as shown in Figure 1 And implementation environment in UE 120 in illustrate.

Optionally, step 402 may alternatively be:

Step 402a detects whether there is the PDN for receiving data service.

The PDN of data service is being received in order to avoid UE is closed without authorization, is reducing user experience, UE can be detected whether first In the presence of the PDN for receiving data service, and preferentially deactivate the PDN of current not received data business.

This step can call execution module to realize by the processor in UE.

Step 402b is receiving the PDN of data service if it exists, is then exporting prompting message, and the prompting message is for mentioning Whether awake user continues to close the data service of LTE network.

If UE detects the PDN for receiving data service, before deactivating the PDN, prompting message can be exported, by User decides whether the data service for continuing to close LTE network.

This step can call execution module to realize by the processor in UE.

Step 402c, receive continue close LTE network data service confirmation instruction after, then execute this to UE with PDN between LTE network carries out deactivated step.

After UE receives the confirmation instruction for the data service for continuing to close LTE network, illustrates that user determines and deactivate just The operation of the PDN between UE and LTE network is deactivated continuing to execute in the PDN for receiving data service, UE.

This step can call execution module to realize by the processor in UE.

Step 403, in only remaining one PDN not being deactivated, the PDN is forbidden to transmit data.

In the lte networks, allow a UE while connecting multiple packet data gateway (English: Packet Data Network Gateway, PDN-GW), UE is also just produced so individually initiates the application scenarios that PDN disconnects request, but UE It must assure that at least one PDN is connect with PDN-GW, otherwise the PDN for refusing UE is disconnected request by LTE network.

This step can call execution module to realize by the processor in UE.

Fig. 4 C is please referred to, it illustrates what an illustrative embodiment of the invention provided, and PDN to be forbidden to transmit data method Flow chart.The present embodiment applies in this way in implementation environment involved in LTE network data method for closing as shown in Figure 1 UE 120 in illustrate.

Optionally, step 403 may alternatively be:

UE is connected in non-LTE network by step 403a, which is GSM network or UMTS network.

In the lte networks, UE must assure that at least one PDN is connect with PDN-GW, and otherwise LTE network will refuse UE's PDN disconnects request, but in GSM network and UMTS network, UE can disconnect all PDN connecting with PDN-GW, if therefore UE The last one PDN connecting with PDN-GW in LTE network is disconnected, needs that the PDN is first connected to non-LTE network (such as GSM Network or UMTS network) on.

This step can call execution module to realize by the processor in UE.

Fig. 4 D is please referred to, it illustrates what an illustrative embodiment of the invention provided, and UE is connected in non-LTE network The flow chart of method.The present embodiment applies to implement involved in LTE network data method for closing as shown in Figure 1 in this way It is illustrated in UE 120 in environment.

Optionally, step 403a may alternatively be:

Step 403a1, control UE are forced away from LTE network, deactivate to PDN, alternatively, controlling the UE attachment removal The attachment removal of LTE network operates.

If UE will disconnect the last one PDN connecting with PDN-GW in LTE network, two ways can be used: first is that control UE processed initiates the detachment process of EMM, second is that the LTE network connected at present is switched to non-LTE network by control UE.

In the second way, it is different from LTE network, in GSM network and UMTS network, UE can be disconnected and PDN-GW All PDN of connection, therefore after UE success is connect with non-LTE network (such as GSM network, UMTS network), so that it may to most The latter PDN is deactivated, so that the disconnection of the PDN, realizes the thorough disconnection of the data communication between UE and LTE network.

This step can call execution module to realize by the processor in UE.

Step 403a2 is searched on net to non-LTE network, or, forcing in gravity treatment to non-LTE network.

Non- LTE network mentioned here typically refer to UE can disconnect connect with PDN-GW in the non-LTE network it is all Network of PDN, such as GSM network, UMTS network etc..

Net mentioned here of searching 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 scanned for, and gravity treatment refers to UE Survey progress network selection in measured PLMN list.

Network selection, cell selection are closely connected together with attaching process.The clothes that UE provides to acquisition network Business, must just select a network, reside in a suitable cell, and successfully complete attaching process.Wherein network selection can To there is automatically and manually two ways, cell selection, attachment are usually to be automatically performed by protocol stack.

This step can call execution module to realize by the processor in UE.

Step 403a3 forbids non-LTE network gravity treatment to LTE network.

Fig. 4 E is please referred to, when closing it illustrates the LTE network data that an illustrative embodiment of the invention provides in UE The schematic diagram of interaction between each physical layer.For searching net, after UE attachment removal LTE network, NAS layers send to AS layers in advance Forbid the order of gravity treatment LTE network, after AS layers receive the order, available GSM network and UMTS network, execution pair will be searched for The measurement of correlation of available GSM network and UMTS network, and be synchronized to cell, receive broadcast to identify network ID, while to NAS Layer reports available GSM network and UMTS network, after NAS receives AS layers of report, first safeguards PLMN list, and report to upper layer Accuse by AS layer provide available GSM network and UMTS network, then automatically or an available GSM network is manually selected by user Or UMTS network, final order AS layer choosing select the cell that one belongs to selected network and provide service.

This step can call execution module to realize by the processor in UE.

In conclusion LTE network data method for closing provided in an embodiment of the present invention, by deactivating UE and LTE network Between PDN only retain a PDN, and forbid the PDN transmit data so that the data communication between UE and LTE network is thorough It disconnects.

Optionally, in other alternative embodiments based on Fig. 4 D, when the control frequent switchback LTE net of UE in user's short time When network, UE will re-establish PDN with LTE network repeatedly, but this process for establishing PDN needs to expend certain time length, in order to The duration that user waits UE and LTE network to establish PDN is reduced as far as possible, improves user experience, UE can be adjusted in predefined conditions The big UE leaves the waiting time before LTE network, when switching back into LTE network in a short time convenient for the UE, can directly with LTE network connection, then the embodiment includes the following steps 403a1a to step 403a1b and step 403a2, please refers to Fig. 4 F, The control UE provided it illustrates an illustrative embodiment of the invention is forced away from LTE network, deactivates to PDN, or Person controls the flow chart of the attachment removal operating method of the UE attachment removal LTE network.

Step 403a1a starts first kind timer.

This step can call execution module to realize by the processor in UE.

Step 403a1b opens LTE network data service if not receiving in the timing length of first kind timer Open command executes control UE and is forced away from LTE network, to PDN then after the timing length of the first kind timer It is deactivated, alternatively, the step of controlling the attachment removal operation of the UE attachment removal LTE network.

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 is in first kind timing The open command for opening LTE network data service is not received in the timing length of device, illustrates user in first kind timer Control UE switchback LTE network is not intended in timing length, UE can continue implementation steps 403a1 at this time.

If UE receives the open command for opening LTE network data service in the timing length of first kind timer, say Bright user intend in the timing length of first kind timer control UE switchback LTE network, at this time UE will keep and LTE network it Between PDN, no longer implementation subsequent step.

This step can call execution module to realize by the processor in UE.

When step 403a1a implement after, can after step 403a2 implementation steps 403a4, wherein step 403a4 and step Rapid 403a3 is without implementation sequence restriction.

Step 403a4 starts the second class timer, refers to if receiving unlatching in the timing length of the second class timer It enables, then tunes up the timing length of first kind timer according to pre-defined rule.

This step can call execution module to realize by the processor in UE.

Referring also to Fig. 4 E, after UE is connect with non-LTE network, start the second class timer, if in the second class timer In timing length, UE receives the open command that LTE network data service is opened in instruction, illustrates that user has multiple switchback LTE net The trend of network, UE will tune up the timing length of first kind timer according to pre-defined rule at this time, i.e., gradually tunes up UE and leave LTE net Waiting time before network.

Optionally, pre-defined rule can be adds up the timing length of first kind timer by scheduled duration.Such as: if UE exists Open command is received in the timing length of second class timer, then is tuned up the timing length of first kind timer 5 seconds.

Optionally, pre-defined rule is also possible to receive open command in the timing length of the second class timer by UE Number is gradually incremented by scheduled duration, the timing length for the first kind timer that adds up.Such as: if UE is for the first time in the timing of the second class Open command is received in the timing length of device, then is tuned up the timing length of first kind timer 5 seconds, if UE second is the Open command is received in the timing length of two class timers, then is tuned up the timing length of first kind timer 10 seconds, with this Analogize.

Optionally, pre-defined rule, which can also be, receives open command in the timing length of the second class timer by UE Duration size between moment and the start-up time of the second class timer, to select the timing length by first kind timer to tune up How much.Such as: the second class timer timing length is 10 seconds, is referred to if UE receives unlatching in 2 seconds after the unlatching of the second class timer It enables, then tunes up the timing length of first kind timer 2 seconds, refer to if UE receives unlatching in 5 seconds after the unlatching of the second class timer It enables, then tunes up the timing length of first kind timer 5 seconds.

The present embodiment has been only exemplified by several possible pre-defined rule forms, but in actual implementation, the form of pre-defined rule It is without being limited thereto.

It should be noted that when the present embodiment is not to the timing of the timing length of first kind timer, the second class timer The specific set-up mode and size of duration involved in long and pre-defined rule are specifically limited.

In conclusion LTE network data method for closing provided in an embodiment of the present invention, by tuning up in predefined conditions The timing length of a kind of timer extends the duration that UE leaves LTE network, when so that UE switching back into LTE network in a short time, It can directly be connect with LTE network, reduce the duration that user waits UE and LTE network to establish PDN, improve user experience.

Optionally, in other alternative embodiments based on Fig. 4 A, when UE receives the finger of unlatching LTE network data service When enabling, in order to make UE may be coupled to optimal LTE cell, then the embodiment includes the following steps 501 to step 502, please join Fig. 5 A is examined, it illustrates the flow charts for the LTE network data method for closing that an illustrative embodiment of the invention provides.

Step 501, UE is connected in non-LTE network, which is GSM network or UMTS network.

This step can call execution module to realize by the processor in UE.

Step 502, LTE neighboring cell list is safeguarded.

In order to quickly switch back into LTE network after so that UE is received the open command of LTE network data service, UE exists After being successfully connected in non-LTE network, LTE neighboring cell list will be safeguarded.

This step can call execution module to realize by the processor in UE.

Step 503, forbid measuring the adjacent area LTE, or, continuing to measure the adjacent area LTE, or, in scheduled duration It is interior that the adjacent area LTE is measured.

From the aspect of reducing UE processor pressure, during UE is connect with non-LTE network, UE can forbid to LTE Adjacent area measures.

From the aspect of making UE quickly be resident optimal L TE cell, during UE is connect with non-LTE network, UE can be after It is continuous that the adjacent area LTE is measured.

Simultaneously consider reduce UE processor pressure and make UE quickly be resident optimal L TE cell the two aspect, UE with it is non- During LTE network connects, UE can continue to measure the adjacent area LTE in scheduled duration or every scheduled duration.

Fig. 5 B is please referred to, UE when closing it illustrates the LTE network data that another exemplary embodiment of the invention provides The schematic diagram of interaction between interior each physical layer.It is that the adjacent area LTE measures specific steps are as follows: NAS layers of initial cell LTE network is selected when search, maintenance accesses limited tracking zone list, safeguards CSG cell white list and its affiliated LTE network And LTE network is supplied to AS layers, after the LTE network of NAS layers of offer is provided when AS layers, the measurement to the adjacent area LTE is executed, is visited While surveying and be synchronized to cell, receive broadcast, related content is reported to NAS layers, is further continued for searching for suitable cell, and will As a result it reports to NAS layers, after searching suitable cell for AS layers, selection is resident in the cell.

This step can call execution module to realize by the processor in UE.

Step 504, the open command that LTE network data service is opened in instruction is received.

This step can call receiving module to realize by the processor in UE.

Step 505, if measuring during the connection of non-LTE network to the adjacent area LTE, the LTE that measured value is optimal is selected Cell accesses LTE network again.
