Realize long-term evolution (English: Long Term Evolution, LTE) network maintains the attachment function through the public data network (English: Public Data Network, PDN). Usually, a PDN needs to be reserved between the mobile phone and the LTE network to make the mobile phone online.

Once the mobile phone is turned on, it establishes a default bearer with the LTE network. When the mobile phone has an Internet Protocol (English: Internet Protocol, IP) address, no matter whether the user uses the network data service, the mobile phone can already communicate with the LTE network. network to communicate. Usually, the LTE network will continuously send data packets to the mobile phone, such as detection packets, broadcast or multicast packets, and heartbeat packets. Since the data volume of these data packets is small, the proportion of the total traffic packets is not high, so users are very It is difficult to perceive traffic sneaking, but when users deliberately do not use network data services, or in some special scenarios, such as mobile phones in roaming state, the data volume of these data packets may be highlighted, and billing disputes may arise. When the mobile phone IP is obtained, or encounters malicious attacks and some network problems, high traffic charges may be incurred.

At present, many mobile phones specially provide LTE data switch. Users can disable LTE by manually turning off the LTE data switch, but this switch only disables LTE, and the network connection between the mobile terminal and the LTE network still exists, so the mobile phone may still generate The phenomenon of traffic stealing.

Please refer to FIG. 3 , which shows a flowchart of a method for disabling data in an LTE network provided by an exemplary embodiment of the present invention. In this embodiment, the method is used in the UE 120 in the implementation environment shown in FIG. 1 as an example. The processor 21 of the UE 120 shown in FIG. 2 performs the following steps, and the method includes the following steps:

Step 301, receiving a closing instruction indicating to close the LTE network data service.

Step 302: Deactivate the PDN between the UE and the LTE network, where the PDN is used to transmit network data packets between the UE and the LTE network.

Step 303, when there is only one PDN that has not been deactivated, prohibit the PDN from transmitting data.

In summary, the LTE network data shutdown method provided by the embodiment of the present invention, by deactivating the PDN between the UE and the LTE network, only one PDN is reserved, and the PDN is prohibited from transmitting data, so that the data between the UE and the LTE network Communication is completely cut off.

Please refer to FIG. 4A , which shows a flowchart of a method for disabling data in an LTE network provided by an exemplary embodiment of the present invention. In this embodiment, the method is applied to the UE 120 in the implementation environment involved in the LTE network data shutdown method shown in FIG. 1 as an example. The method includes the following steps:

Step 401, receiving a closing instruction indicating to close the LTE network data service.

Usually, once the UE is powered on, it establishes a default bearer with the LTE network. That is to say, the PDN connection management process is closely related to the default bearer management process, both of which belong to the EPS session management (English: EPSSession Management, ESM) process, but are usually associated with the EPS mobility management (English: EPSMobility management, EMM) attachment process Accompanied, that is, when the UE sends an attach request to the LTE network, it will initiate a PDN request, and when the LTE network receives the attach request sent by the UE, it will activate the default bearer at the same time.

When the user performs an operation to close the LTE network, the UE will receive a close command indicating to close the data service of the LTE network, and request to disconnect the PDN from the PDN-GW in the LTE network.

This step can be implemented by the processor in the UE calling the receiving module.

Step 402: Deactivate the PDN between the UE and the LTE network, where the PDN is used to transmit network data packets between the UE and the LTE network.

When the PDN-GW receives the PDN disconnection request from the UE, it will release all dedicated bearers associated with the PDN, and initiate a bearer deactivation process.

It should be noted that the PDN mentioned in this embodiment is a PDN for transmitting network data packets between the UE and the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Please refer to FIG. 4B , which shows a flowchart of a method for deactivating a PDN between a UE and an LTE network according to an exemplary embodiment of the present invention. This embodiment is illustrated by taking the method applied to UE 120 in the implementation environment involved in the method for disabling data in the LTE network as shown in FIG. 1 .

Optionally, step 402 can be replaced by:

Step 402a, detecting whether there is a PDN receiving data services.

In order to prevent the UE from arbitrarily deactivating the PDN that is receiving the data service and degrading user experience, the UE may first detect whether there is a PDN that is receiving the data service, and deactivate the PDN that is not currently receiving the data service first.

This step can be implemented by the processor in the UE calling the execution module.

Step 402b, if there is a PDN that is receiving the data service, output reminder information, the reminder information is used to remind the user whether to continue to close the data service of the LTE network.

If the UE detects a PDN that is receiving data services, it will output a reminder before deactivating the PDN, and it is up to the user to decide whether to continue to shut down the data services of the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Step 402c, after receiving the confirmation instruction to continue to shut down the data service of the LTE network, execute the step of deactivating the PDN between the UE and the LTE network.

When the UE receives the confirmation instruction to continue disabling the data service of the LTE network, it means that the user has determined to deactivate the PDN that is receiving the data service, and the UE will continue to perform the operation of deactivating the PDN between the UE and the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Step 403, when there is only one PDN that has not been deactivated, prohibit the PDN from transmitting data.

In the LTE network, a UE is allowed to connect to multiple packet data gateways (English: Packet DataNetwork Gateway, PDN-GW) at the same time, which also creates an application scenario where the UE initiates a PDN disconnection request independently, but the UE must ensure at least one PDN Connect with the PDN-GW, otherwise the LTE network will reject the UE's PDN disconnection request.

This step can be implemented by the processor in the UE calling the execution module.

Please refer to FIG. 4C , which shows a flowchart of a method for prohibiting a PDN from transmitting data provided by an exemplary embodiment of the present invention. This embodiment is illustrated by taking the method applied to UE 120 in the implementation environment involved in the method for disabling data in the LTE network as shown in FIG. 1 .

Optionally, step 403 can be replaced by:

Step 403a, connect the UE to a non-LTE network, where the non-LTE network is a GSM network or a UMTS network.

In the LTE network, the UE must ensure that at least one PDN is connected to the PDN-GW, otherwise the LTE network will reject the UE's PDN disconnection request, but in the GSM network and UMTS network, the UE can disconnect all PDNs connected to the PDN-GW Therefore, if the UE wants to disconnect the last PDN connected to the PDN-GW in the LTE network, it needs to connect the PDN to a non-LTE network (such as a GSM network or a UMTS network) first.

This step can be implemented by the processor in the UE calling the execution module.

Please refer to FIG. 4D , which shows a flowchart of a method for connecting a UE to a non-LTE network according to an exemplary embodiment of the present invention. This embodiment is illustrated by taking the method applied to UE 120 in the implementation environment involved in the method for disabling data in the LTE network as shown in FIG. 1 .

Optionally, step 403a can be replaced by:

In step 403a1, the UE is controlled to forcibly leave the LTE network, and the PDN is deactivated, or the UE is controlled to detach from the LTE network.

If the UE wants to disconnect the last PDN connected to the PDN-GW in the LTE network, two methods can be adopted: one is to control the UE to initiate the EMM detachment process, and the other is to control the UE to switch the currently connected LTE network to a non-LTE network network.

In the second way, different from LTE network, in GSM network and UMTS network, UE can disconnect all PDNs connected with PDN-GW, so when UE successfully connects with non-LTE network (such as GSM network, UMTS network) After that, the last PDN can be deactivated, so that the PDN is disconnected, and the data communication between the UE and the LTE network is completely disconnected.

This step can be implemented by the processor in the UE calling the execution module.

Step 403a2, search the network to a non-LTE network, or force reselection to a non-LTE network.

The non-LTE network mentioned here usually refers to the network where the UE can disconnect all PDNs connected to the PDN-GW in the non-LTE network, such as GSM network, UMTS network and so on.

The network search mentioned here means that the UE does not select a network in the measured public land mobile network (Public Land Mobile Network, PLMN) list, but directly searches for the available network, and the reselection means that the UE does not select the network in the measured public land mobile network (PLMN) list. Network selection from the list of good PLMNs.

Network selection, cell selection and attachment process are closely linked. To obtain services provided by the network, the UE must select a network, reside in a suitable cell, and successfully complete the attach process. Among them, network selection can be in two ways, automatic and manual, and cell selection and attachment are usually completed automatically by the protocol stack.

This step can be implemented by the processor in the UE calling the execution module.

Step 403a3, forbid the non-LTE network to reselect to the LTE network.

Please refer to FIG. 4E , which shows a schematic diagram of interaction between various physical layers in the UE when LTE network data is turned off according to an exemplary embodiment of the present invention. Taking Souwang as an example, after the UE deattaches to the LTE network, the NAS layer sends a command to the AS layer in advance to prohibit reselection of the LTE network. After receiving the command, the AS layer will search for available GSM networks and UMTS networks, and execute related measurements of the GSM network and UMTS network, synchronize to the cell, receive broadcasts to identify the network ID, and report the available GSM network and UMTS network to the NAS layer. After receiving the report from the AS layer, the NAS maintains the PLMN list first, and Report the available GSM network and UMTS network provided by the AS layer to the upper layer, then automatically or manually select an available GSM network or UMTS network by the user, and finally order the AS layer to select a cell belonging to the selected network to provide services.

This step can be implemented by the processor in the UE calling the execution module.

In summary, the LTE network data shutdown method provided by the embodiment of the present invention reserves only one PDN by deactivating the PDN between the UE and the LTE network, and prohibits the PDN from transmitting data, so that the data communication between the UE and the LTE network Completely disconnected.

Optionally, in other optional embodiments based on FIG. 4D , when the user controls the UE to frequently switch back to the LTE network in a short period of time, the UE will repeatedly re-establish the PDN with the LTE network, but this process of establishing the PDN requires a lot of time. A certain length of time, in order to minimize the time for the user to wait for the UE to establish a PDN with the LTE network and improve user experience, under predetermined conditions, the UE can increase the waiting time before the UE leaves the LTE network, so that the UE can switch back to LTE in a short time network, it can be directly connected to the LTE network, then this embodiment includes the following steps 403a1a to 403a1b and 403a2, please refer to Figure 4F, which shows the control UE is forced to leave the LTE network provided by an exemplary embodiment of the present invention, A flowchart of a deactivation operation method for deactivating the PDN, or controlling the UE to detach from the LTE network.

Step 403a1a, start the first type of timer.

This step can be implemented by the processor in the UE calling the execution module.

Step 403a1b, if the instruction to start the LTE network data service is not received within the timing duration of the first type of timer, then after the timing duration of the first type of timer ends, execute the control UE to forcibly leave the LTE network. The PDN performs deactivation, or controls the UE to detach from the LTE network.

The timing duration of the first timer mentioned here refers to the waiting duration before the UE leaves the LTE network.

After the UE deactivates the PDN between the UE and the LTE network, the first type of timer is started. If the UE does not receive the instruction to enable the data service of the LTE network within the duration of the first type of timer, it means that the user It is not intended to control the UE to switch back to the LTE network within the timing duration of a type of timer, and at this time, the UE may continue to implement step 403a1.

If the UE receives an instruction to start the LTE network data service within the timing duration of the first type of timer, it means that the user intends to control the UE to switch back to the LTE network within the timing duration of the first type of timer. PDN between networks, no further steps are implemented.

This step can be implemented by the processor in the UE calling the execution module.

After step 403a1a is implemented, step 403a4 may be implemented after step 403a2, wherein there is no limitation on the order of implementation of step 403a4 and step 403a3.

In step 403a4, start the second type of timer, and if an activation instruction is received within the timing duration of the second type of timer, increase the timing duration of the first type of timer according to a predetermined rule.

This step can be implemented by the processor in the UE calling the execution module.

Still referring to Figure 4E, when the UE is connected to a non-LTE network, the second type of timer is started. If within the timing duration of the second type of timer, the UE receives an instruction to enable the LTE network data service, it means that the user has The trend of switching back to the LTE network for the second time, at this time, the UE will increase the timing length of the first type of timer according to the predetermined rules, that is, gradually increase the waiting time before the UE leaves the LTE network.

Optionally, the predetermined rule may be to accumulate the timing duration of the first type of timer according to the predetermined duration. For example: if the UE receives an activation instruction within the timing duration of the second type of timer, the timing duration of the first type of timer is increased by 5 seconds.

Optionally, the predetermined rule may also be to gradually increase the predetermined duration according to the number of times the UE receives the activation instruction within the timing duration of the second type of timer, and accumulate the timing duration of the first type of timer. For example: if the UE receives the start command for the first time within the timing duration of the second type timer, it will increase the timing duration of the first type timer by 5 seconds; If the opening command is received within the time period, the timing time of the first type of timer is increased by 10 seconds, and so on.

Optionally, the predetermined rule may also be to select the first-type timer according to the time length between the time when the UE receives the start instruction within the timing duration of the second-type timer and the time when the second-type timer is turned on. How much to increase the timing duration. For example: the timing duration of the second type of timer is 10 seconds. If the UE receives the start instruction 2 seconds after the second type of timer is started, it will increase the timing duration of the first type of timer by 2 seconds. If the start instruction is received 5 seconds after the timer is started, the timing duration of the first timer is increased by 5 seconds.

This embodiment only exemplifies several possible forms of the predetermined rule, but in actual implementation, the form of the predetermined rule is not limited thereto.

It should be noted that this embodiment does not specifically limit the timing duration of the first type of timer, the timing duration of the second type of timer, and the specific setting method and size of the duration involved in the predetermined rule.

In summary, the LTE network data shutdown method provided by the embodiment of the present invention increases the timing duration of the first type of timer under predetermined conditions, prolonging the time for the UE to leave the LTE network, so that the UE switches back to the LTE network in a short time , it can be directly connected to the LTE network, reducing the time for users to wait for the UE to establish a PDN with the LTE network, and improving user experience.

Optionally, in other optional embodiments based on FIG. 4A, when the UE receives an instruction to enable the LTE network data service, in order to enable the UE to connect to the optimal LTE cell, this embodiment includes the following steps 501 to Step 502, please refer to FIG. 5A , which shows a flow chart of a method for disabling LTE network data provided by an exemplary embodiment of the present invention.

Step 501, connect the UE to a non-LTE network, and the non-LTE network is a GSM network or a UMTS network.

The non-LTE network mentioned here usually refers to the network where the UE can disconnect all PDNs connected to the PDN-GW in the non-LTE network, such as GSM network, UMTS network and so on.

This step can be implemented by the processor in the UE calling the execution module.

Step 502, maintaining an LTE neighbor list.

In order for the UE to quickly switch back to the LTE network after receiving the start instruction of the LTE network data service, the UE will maintain the LTE neighbor list after successfully connecting to the non-LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Step 503, prohibiting the measurement of the LTE neighboring cells, or continuing to measure the LTE neighboring cells, or performing measurement of the LTE neighboring cells within a predetermined time period.

From the perspective of reducing the pressure on the UE processor, the UE may prohibit measurement of LTE neighboring cells when the UE is connected to a non-LTE network.

From the aspect of allowing the UE to quickly camp on the optimal LTE cell, the UE can continue to measure LTE neighbor cells during the connection between the UE and the non-LTE network.

At the same time, considering the two aspects of reducing the pressure on the UE processor and allowing the UE to quickly camp on the optimal LTE cell, when the UE is connected to a non-LTE network, the UE can continue to measure the LTE neighboring cells within a predetermined period of time or every predetermined period of time.

Please refer to FIG. 5B , which shows a schematic diagram of interaction between various physical layers in the UE when LTE network data is turned off according to another exemplary embodiment of the present invention. The specific operation steps for measurement of LTE neighbor cells are as follows: the NAS layer selects the LTE network during the initial cell search, maintains the access restricted tracking area list, maintains the CSG cell whitelist and the LTE network it belongs to, and provides the LTE network to the AS layer, After the AS layer receives the LTE network provided by the NAS layer, it performs the measurement of the LTE neighboring cells, detects and synchronizes to the cell, receives the broadcast, and reports the relevant content to the NAS layer, then continues to search for a suitable cell, and reports the result Report to the NAS layer. When the AS layer searches for a suitable cell, it chooses to reside in the cell.

This step can be implemented by the processor in the UE calling the execution module.

Step 504, receiving an enabling instruction indicating enabling the LTE network data service.

This step can be implemented by the processor in the UE calling the receiving module.

Step 505, if the LTE neighbor cell is measured during the non-LTE network connection period, select the LTE cell with the best measurement value, and re-connect to the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Step 506: If the LTE neighbor cell is not measured during the non-LTE network connection period, measure the LTE neighbor cell, select the LTE cell with the best measurement value, and re-connect to the LTE network.

Before the UE re-joins the LTE network, the UE must select a suitable cell to camp on in the LTE network and successfully complete the attach process. Therefore, when re-connecting to the LTE network, the UE needs to measure the LTE neighboring cells, and select the LTE cell with the best measurement value to camp on. That is to say, if the UE measures the LTE neighboring cells during the non-LTE network connection, Then, when the UE receives the start instruction indicating to start the LTE network data service, it can directly select the LTE cell with the best measurement value and re-connect to the LTE network. If the UE has not measured the LTE neighboring cells during the non-LTE network connection, then after the UE receives the instruction to enable the LTE network data service, it can first measure the LTE neighboring cells, and then select the LTE cell with the best measurement value , reconnect to the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

It should be noted that step 501 is similar to step 403a, so step 501 will not be repeated in this embodiment.

To sum up, in the method for disabling LTE network data provided by the embodiment of the present invention, after the UE receives the instruction to enable the LTE network data service, it first measures the LTE neighboring cells, selects the LTE cell with the best measured value, and then Re-connecting to the LTE network enables the UE to access the LTE network with better network speed and better quality, improving user experience.

Optionally, in other optional embodiments based on FIG. 4A , in addition to controlling the UE to initiate EMM detachment and controlling the UE to switch the currently connected LTE network to a non-LTE network, a suspension request may also be sent to the core network , so that the core network stops sending data information to the PDN, then this embodiment includes the following steps 601 to 605, please refer to FIG. 6A, which shows the business continuity test method of the database provided by an exemplary embodiment of the present invention. flow chart.

Step 601, receiving a closing instruction indicating to close the LTE network data service.

This step can be implemented by the processor in the UE calling the receiving module.

Step 602: Deactivate the PDN between the UE and the LTE network, where the PDN is used to transmit network data packets between the UE and the LTE network.

This step can be implemented by the processor in the UE calling the execution module.

Step 603, sending a suspension request to the core network.

The suspension request is used to trigger the core network to suspend the PDN with the UE. After the PDN is suspended, the core network stops sending data services and paging to the PDN.

Optionally, the suspension request may be an extended service request (English: Extended Service Request, ESR), a service request (English: Service Request, SR) or a tracking area update (English: TrackingArea Update, TAU) signaling, etc.

This step can be implemented by the processor in the UE calling the sending module.

When the UE receives the activation command, it will send a disconnection request to the core network to resume data transmission between the UE and the core network. Please refer to FIG. 6B , which shows a flow chart of a method for disabling data in an LTE network according to yet another exemplary embodiment of the present invention.

Step 604, receiving an enabling instruction indicating enabling the LTE network data service.

This step can be implemented by the processor in the UE calling the receiving module.

Step 605, sending a request for disconnection to the core network.

The disconnection request is used to trigger the core network to disconnect the PDN between the UE and the core network to resume sending data services and paging to the PDN after the PDN is disconnected.

Optionally, the unhook request may be ESR, SR, or TAU signaling.

This step can be implemented by the processor in the UE calling the receiving module.

Please refer to FIG. 6C , which shows a schematic diagram of interaction between the UE and the core network when LTE network data is turned off according to an exemplary embodiment of the present invention.

It should be noted that Step 601 to Step 602 are similar to Step 401 to Step 402, so this embodiment will not repeat Step 601 and Step 602 again.

In summary, the LTE network data shutdown method provided by the embodiment of the present invention sends a suspension request to the core network after the UE receives the shutdown command, and sends a suspension request to the core network after the UE receives the startup command, so that Even if there is a PDN between the UE and the core network, the core network no longer sends data services and paging to the PDN, so that the data communication between the UE and the LTE network is completely disconnected.
