Description

Network switching method, device and terminal

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a network switching method, apparatus, and terminal.

Background technique

At present, China Telecom has deployed the 4th Generation Communication System (4G) network in some cities, and set a 4G switch on the 4G terminal to control whether the terminal registers the 4G network.

Set a “Enable 4G” switch on the terminal. When the “Enable 4G” switch is turned on, the working mode of the terminal is Long Time Evolution (LTE) and Code Division Multiple Access (CDMA). Broadband code division multiple access (Wide-band CDMA, WCDMA for short), Global System for Mobile Communication (GSM) hybrid mode; when the "Enable 4G" switch is off, the terminal's working mode is CDMA, WCDMA, GSM hybrid mode. Specifically, according to the requirements of China Telecom, when the “Enable 4G” switch is turned on or off, the terminal performs network switching as follows: “Enable 4G” switch is turned off to open, and if the terminal is in idle state, the terminal immediately searches again and If the terminal is in the service state, the user is prompted to interrupt the current service and search for and access the LTE network; the "Enable 4G" switch is switched from open to closed, and the terminal immediately follows the Evolved High Rate Packet Date (Evolved High Rate Packet Date, Referring to the EHRPD network, the High Rate Packet Date (HRPD) network, and the priority of the 1x Radio Transmission Technology (1x RTT) network, the network access is searched in turn, that is, the "Enable 4G" switch is turned off. The terminal preferentially registers with the EHRPD network. If the EHRPD network cannot be registered, it gradually falls back down and registers with the HRPD network.

However, due to the incomplete network deployment and configuration of the carrier, the following two scenarios occur:

1. The user has processed the 4G card but has not activated the 4G service. As a result, the terminal cannot access the 4G network. The terminal preferentially registers the EHRPD network, but the local EHRPD network data service is unavailable, making the terminal unable to perform data services.

2. The 4G card handled by the user has opened the 4G service, but in the area where there is no LTE network coverage, The terminal preferentially registers the EHRPD network, but the local EHRPD network data service is unavailable, making the terminal unable to perform data services.

In the above two scenarios, after the terminal is plugged into the 4G card, if the terminal preferentially registers with the EHRPD network, when the EHRPD network data service is unavailable, the data service cannot be performed regardless of whether the 4G switch of the terminal is turned on or off, thereby reducing the performance of the terminal. .

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The network switching method provided by the embodiment of the present invention is applied to a terminal, for example, a mobile phone or a notebook. Computers, tablets, handheld terminals, etc., are suitable for scenarios where the terminal switches from one network to another, for example, when the mobile phone switches from a 3G network to a 4G network, or when the mobile phone does not successfully access the 4G network, it can be switched. Go to other networks and other scenarios.

FIG. 1 is a flowchart of a network switching method according to Embodiment 1 of the present invention. As shown in Figure 1, the method includes the following steps:

Step 101: Determine that the terminal cannot use the LTE network for data services.

In this embodiment, the 4G network may adopt the LTE technology. When the user does not open the 4G service, or the current serving cell where the terminal is located is not covered by the LTE network, or the LTE network fails, data services cannot be performed, etc., in these scenarios. The terminal cannot use the LTE network for data services.

Step 102: Monitor service parameters of data service activation failure under the EHRPD network.

The service parameters include the number of times the data service activation fails or the reason why the data service activation fails.

In this embodiment, after the terminal is plugged into the 4G card but cannot access the 4G network, the terminal preferentially registers the EHRPD network. After the terminal registers the EHRPD network successfully, the terminal performs data service activation under the EHRPD network, and monitors the terminal in the EHRPD. The number of times the data service fails to be activated in the network or the cause of the failure of the data service activation. You can set a static counter in the terminal to count the number of failed data service activations. The cause of data service activation failure is the cause of data service activation failure. The terminal may obtain the cause value of the failure of the data service activation through the processor of the terminal due to the failure caused by the instability of the EHRPD network and the failure caused by the unavailable network connection.

In step 103, it is determined whether the service parameter meets the first condition. If the service parameter meets the first condition, step 104 is performed. If the service parameter does not meet the first condition, step 105 is performed.

The first condition is a condition that the preset terminal exits the EHRPD network.

In this embodiment, the first condition is a condition that the preset terminal exits the EHRPD network, and the first condition may be set according to the specific content of the service parameter. For example, if the service parameter is the number of times the data service fails to be activated, The first condition is set to the maximum number of repetitions of the data service activation. When the number of data service activation failures exceeds the maximum number of repetitions, the service parameter meets the first condition. When the number of data service activation failures is less than or equal to the maximum number of repetitions, the service is performed. The parameter does not meet the first condition.

Step 104: Exit the EHRPD network and request access to the HRPD network.

In this embodiment, when the service parameter meets the first condition, the terminal automatically exits the EHRPD network, and then searches for and requests access to the HRPD network. If the HRPD network is successfully accessed, the data service is used under the HRPD network. A global variable can be set in the processor to control the terminal to access or exit the EHRPD network.

Step 105: Perform data service activation.

In this embodiment, when the service parameter does not meet the first condition, the terminal re-activates the data service. If the activation fails, step 101 is continued.

In the prior art, when the terminal handles the 4G card but cannot access the 4G network, the terminal preferentially registers with the EHRPD network. However, due to the incomplete network configuration and deployment of the operator, the EHRPD network has many problems, for example, the data service cannot be activated. The Assisted Global Positioning System (AGPS) is slow to locate and the data service is easily interrupted. Therefore, after registering the EHRPD network, the terminal still cannot use the data service under the EHRPD network. However, the terminal cannot be closed. After the EHRPD network switches to another network, the 4G card inserted in the terminal causes the data service to be performed regardless of whether the 4G switch of the terminal is turned on or off, which reduces the performance of the terminal. In this embodiment, when it is determined that the terminal cannot use the LTE network to perform data services, the terminal monitors the service parameters of the data service activation failure in the EHRPD network. When the service parameters meet the first condition, the terminal automatically exits the EHRPD network, and then searches for Requesting access to the HRPD network and using the data service in the HRPD network. Since the HRPD network is relatively stable, the terminal can perform data services under the HRPD network, so that when the terminal inserts the 4G card but cannot access the 4G network, the terminal can quickly fall back to The data service is performed on the HRPD network, which effectively improves the performance of the terminal.

The network switching method provided in this embodiment determines that the terminal cannot use the LTE network to perform the data service, and the terminal monitors the service parameter of the data service activation failure in the EHRPD network. When the service parameter meets the first condition, the terminal automatically exits the EHRPD network. Then, it searches for and requests access to the HRPD network, and uses the data service under the HRPD network, so that when the terminal inserts the 4G card but cannot access the 4G network, the terminal can quickly fall back to the HRPD network for data services, thereby effectively improving the performance of the terminal.

FIG. 2 is a flowchart of a network switching method according to Embodiment 2 of the present invention. On the basis of the first embodiment shown in FIG. 1 , as shown in FIG. 2 , if the service parameter is the number of times the data service fails to be activated, the first condition includes the maximum number of retries for the terminal to perform data service activation; The implementation of the step of whether the parameter meets the first condition specifically includes the following steps:

Step 205: Determine whether the number of service activation failures is greater than the maximum number of retries. If yes, that is, the number of service activation failures is greater than the maximum number of retries, step 206 is performed. If not, the number of service activation failures is not greater than the maximum number of retries. Then step 207 is performed.

In this embodiment, after the terminal fails to activate the data service, the data service is reactivated, and the maximum number of retries for the data service activation by one terminal is preset, and the maximum number of retries is guaranteed to be accidental. In this case, the terminal retry normally, and ensure that the terminal exits the EHRPD network as soon as possible after determining that the EHRPD network has a network fault, so that the terminal accesses the HRPD network as soon as possible. Generally, the maximum number of retries is set to 2 or 3 times. However, the present invention is not limited thereto, and those skilled in the art can set the maximum number of retries according to the actual situation.

Step 206: Determine that the service parameter meets the first condition.

In this embodiment, when the number of service activation failures is greater than the maximum number of retries, it is determined that the service parameters meet the first condition.

Step 207: Determine that the service parameter does not meet the first condition.

In this embodiment, when the number of service activation failures is less than or equal to the maximum number of retries, it is determined that the service parameters do not meet the first condition.

Optionally, in this embodiment, as shown in FIG. 2, before step 205, the following steps are further included:

Step 201: Obtain a cause value of failure of data service activation.

In this embodiment, the terminal may obtain a cause value of the data service failure by using the processor.

Step 202: Determine whether the cause value of the data service activation failure meets the second condition; if not, that is, the reason value of the data service activation failure does not meet the second condition, perform step 203, and if yes, the cause value of the data service activation failure is met. In the second condition, step 204 is performed.

The second condition is that the terminal fails to activate the data service because the network fails, and the current network is an EHRPD network.

In this embodiment, the network failure refers to data activation failure due to network failure, for example, the network signal is too weak, or the network signal is interrupted, so that the terminal cannot perform data service. If the cause of the data service activation failure is a network failure, and the network currently used by the terminal is an EHRPD network, the cause value of the data service activation failure is determined to meet the second condition; if the reason for the data service activation failure is not the network failure, or If the current network is not an EHRPD network, the reason for determining that the data service activation fails does not meet the second condition.

Step 203: Clear the number of times the last data service activation failed.

In this embodiment, in the EHRPD network, the number of times the data service activation fails after each data service activation failure is determined. If the reason for the failure of the data service activation fails to meet the second condition, the data service recorded last time is recorded. The number of activation failures is cleared.

In step 204, the number of times the data service activation failed is incremented by one.

In this embodiment, if it is determined that the cause value of the data service activation failure meets the second condition, that is, the reason that the data service activation fails is the network failure, and the current network used by the terminal is the EHRPD network, the last record is The number of data service activation failures is increased by one.

It should be noted that the other steps in this embodiment are the same as those in the first embodiment, and details are not described herein again.

In the network switching method provided in this embodiment, if the service parameter is the number of times the data service is activated, the first condition includes the maximum number of retries for the data service activation, and the number of times the service activation failure is greater than the maximum number of retries. If yes, determining that the service parameter meets the first condition, exiting the EHRPD network and requesting access to the HRPD network; if not, determining that the service parameter does not meet the first condition, then performing data service activation, when the service parameter meets the first condition, The terminal automatically quits the EHRPD network, then searches for and requests access to the HRPD network, and uses the data service under the HRPD network. Since the HRPD network is relatively stable, the terminal can perform data services under the HRPD network, so that the terminal cannot connect after inserting the 4G card. When entering a 4G network, you can quickly fall back to the HRPD network for data services, which effectively improves the performance of the terminal. In addition, in this embodiment, before determining whether the number of times the service activation failure is greater than the maximum number of retries, the method further includes: obtaining a cause value of the data service activation failure, and determining whether the cause value of the data service activation failure meets the second condition, and if yes, The number of times the data service activation fails is increased by one. If not, the number of data service activation failures is cleared. The data service is only valid when the cause of the data service activation failure is the network failure and the current network is the EHRPD network. The number of activation failures is increased by 1. In other cases, the reason for the failure of the data service activation is cleared, and the problem of blindly shutting down the EHRPD network and improving the terminal is avoided when the data service activation failure occurs due to some non-network failure reasons. performance.

FIG. 3 is a flowchart of a network switching method according to Embodiment 3 of the present invention. On the basis of the first embodiment shown in FIG. 1 , as shown in FIG. 3 , if the service parameter is the cause value of the data service activation failure, the first condition includes that the reason for the terminal to fail the data service activation under the EHRPD network is permanent. Sexual failure; the specific implementation of the step of "determining whether the service parameters meet the first condition" includes the following steps:

Step 301: Determine whether the cause value of the data service activation failure is a permanent failure. If the value of the data service activation failure is a permanent failure, go to step 302. If no, the cause of the data service activation failure is not permanent. If the sex fails, step 303 is performed.

In this embodiment, the permanent failure refers to the failure of the EHRPD network, and the terminal cannot use the data service under the EHRPD network regardless of how many data service activations are attempted. For example, the failure of the network side device causes the entire network signal to be interrupted, and Can't recover in a short time.

Step 302: Determine that the service parameter meets the first condition.

In this embodiment, if the cause value of the data service activation failure is a permanent failure, it is determined that the service parameter meets the first condition.

Step 303: Determine that the service parameter does not meet the first condition.

In this embodiment, if the cause value of the data service activation failure is not a permanent failure, it is determined that the service parameter does not meet the first condition.

The network switching method provided in this embodiment, if the service parameter is the cause value of the data service activation failure; the first condition includes the reason that the terminal fails to perform the data service activation in the EHRPD network is a permanent failure, and the reason for the data service activation failure is determined. Whether the value is a permanent failure. If yes, it is determined that the service parameter meets the first condition, the terminal exits the EHRPD network and requests access to the HRPD network; if not, it determines that the service parameter does not meet the first condition, and continues to perform data service on the EHRPD network. When the service parameters meet the first condition match, the terminal automatically exits the EHRPD network, then searches for and requests access to the HRPD network, and uses the data service under the HRPD network. Since the HRPD network is relatively stable, the terminal can perform the HRPD network. The data service enables the terminal to quickly fall back to the HRPD network for data services when the 4G card is inserted but cannot access the 4G network, which effectively improves the performance of the terminal.

FIG. 4 is a flowchart of a network switching method according to Embodiment 4 of the present invention. On the basis of the foregoing embodiment 1, after the step of "monitoring the service parameters of the data service activation failure in the evolved high-speed packet EHRPD network", as shown in FIG. 4, the method further includes the following steps:

Step 401: Determine, according to the cause value of the data service activation failure, whether the processor needs to be restarted. If yes, if the processor needs to be restarted, go to step 402; if no, if the processor does not need to be restarted, go to step 403.

In this embodiment, the terminal determines whether it is necessary to restart the processor according to the cause value of the data service activation failure. For example, if the reason value is due to the failure of the processor of the terminal, the data service activation fails, the processor needs to be restarted. If the cause value is not due to data failure of the terminal's processor failure, there is no need to restart the processor.

Step 402: Restart the processor.

In this embodiment, if the data service activation failure is caused by a failure of the processor of the terminal, the processor is restarted, and after restarting the processor, the data service activation is retried.

Step 403: Determine whether the data type of the access point corresponding to the terminal meets the preset data type. If yes, that is, the data type of the access point conforms to the preset data type, perform step 404; or, if not, the access point If the data type does not match the preset data type, step 405 is performed.

In this embodiment, the preset data type includes multiple data types commonly used by the access point, for example, a system default (DEFAULT) type, a multimedia message service (MMS) type, and the like. When the processor does not need to be restarted, the data type of the access point corresponding to the terminal is determined. When the data type of the access point is any one of the preset data types, the data type of the access point conforms to the preset. The data type. When the data type of the access point is not one of the preset data types, the data type of the access point does not match the preset data type. For example, if the preset data type includes DEFAULT and MMS, when the data type of the access point is DEFAULT or MMS, it conforms to the preset data type, and continues to determine whether to exit the EHRPD network. When the data type of the access point is not DEFAULT or When the MMS is not in compliance with the preset data type, the normal processing logic step is maintained, that is, the data service activation is re-attempted. After the data service activation fails, the number of times and the cause value of the data service activation failure are continuously monitored.

Step 404: Perform the step of determining whether the service parameter meets the first condition.

In this embodiment, when the data type of the access point corresponding to the terminal meets the preset data type, it is further determined whether the service parameter meets the first condition, and the subsequent steps are the same as those in the first embodiment, and details are not described herein again. .

Step 405: Perform data service activation.

In this embodiment, if the data type of the access point corresponding to the terminal does not meet the preset data type, the retry attempts to activate the data service, and if the data service fails to be activated, the number of times and the cause value of the data service activation failure are continuously monitored; If the data service is activated successfully, the data service is used.

The network switching method provided by this embodiment, the terminal monitors the data service under the EHRPD network After the failed service parameter is activated, it is determined whether the processor needs to be restarted according to the reason for the failure of the data service activation. If necessary, the processor is restarted. If not, the data type of the access point corresponding to the terminal is determined to be in accordance with the preset. Data type. If the data type of the access point meets the preset data type, perform the step of determining whether the service parameter meets the first condition, and determine whether to exit the EHRPD network according to the result, if the data type of the access point does not meet the preset Data type, then data service activation. In this embodiment, for the case where the data activation failure caused by the failure of the processor fails, the processor needs to be restarted, and the data service activation is retried for the case that the data service activation fails due to the unusual data type of the access point. Therefore, the problem of blindly exiting the EHRPD network when the data service activation fails due to the failure of the processor of the terminal or the non-network cause of the data type is not avoided, and the method of restarting the processor and retrying the data service activation may be used. The terminal can use the data service normally under the EHRPD network, which effectively improves the performance of the terminal.

Preferably, after the EHRPD network is exited on the basis of any one of the foregoing Embodiments 1 to 4, the method further includes: if the LTE network is successfully registered, checking whether the EHRPD network identifier of the terminal is an active state; The EHRPD network identifier of the terminal is in an active state, and the terminal requests to access the EHRPD network after exiting the LTE network.

In this embodiment, after exiting the EHRPD network, if the terminal needs to re-search for the LTE network, for example, if the 4G switch of the terminal is re-enabled, or the terminal restarts, the terminal starts to search for the LTE network, and successfully registers the LTE network. After that, the EHRPD network identifier of the terminal is checked, and the EHRPD network identifier can be set in the processor. If the EHRPD network identifier is in the active state, the terminal requests to access the EHRPD network after exiting the LTE network. If the EHRPD network identifier is inactive, the data service is activated. After the terminal re-registers the LTE network, after exiting the LTE network, the terminal can select whether to access the EHRPD network according to the status of the EHRPD network identifier, so that the operation of exiting the EHRPD network when the data service fails to be activated has the current line and the current validity. Instead of simply and rudely exiting the EHRPD network completely, when the terminal cannot perform data services under the LTE network, and the EHRPD network is available for recovery, the terminal can access the EHRPD network and use the data service normally, thereby improving the stability of the terminal.

FIG. 5 is a flowchart of a network switching method according to Embodiment 5 of the present invention. As shown in FIG. 5, the method includes the following steps:

Step 501: Detect whether the 4G service of the terminal is activated.

In this embodiment, a 4G switch can be set in the terminal. For example, for an Android terminal, a “Enable 4G” switch can be set in the system setting item to control whether the terminal registers the 4G network, and the 4G switch. The status includes two states: "on" and "off". When the status of the 4G switch is "on", the 4G service of the terminal is activated. When the status of the 4G switch is "off", the 4G service of the terminal is not activated.

Step 502: If it is determined that the 4G service is activated, it is determined that the terminal cannot use the LTE network to perform data service, and requests to access the EHRPD network; or if it is detected that the 4G service is not activated, it is determined that the terminal cannot use the LTE network for data service. When requesting access to the HRPD network.

In this embodiment, the 4G switch and the EHRPD network may be associated together. When the 4G switch is detected to be activated, that is, the 4G service is activated, and the terminal automatically requests to access the EHRPD network when the LTE network cannot be used; When the 4G switch is disabled, that is, the 4G service is not activated, the terminal no longer preferentially registers with the EHRPD network, but directly searches for and requests access to the HRPD network, and uses the data service under the HRPD network.

The network switching method provided in this embodiment is to detect whether the 4G service is activated. If the 4G service is activated, it is determined that the terminal cannot use the LTE network to perform data service, and requests to access the EHRPD network; or, if the 4G service is detected. If it is not activated, it is determined that the terminal cannot use the LTE network for data service, and requests to access the HRPD network. When the terminal 4G service is closed, the terminal no longer preferentially registers the EHRPD network, but directly searches for and requests access to the HRPD network. The use of data services under a stable HRPD network improves the performance of the terminal.

Preferably, in the fifth embodiment, the method further includes: after detecting that the 4G service is activated, modifying the EHRPD network identifier of the terminal to an activated state; or detecting the EHRPD network identifier of the terminal after detecting that the 4G service is not activated. Modified to inactive.

In this embodiment, the EHRPD network identifier may be set in the processor of the terminal, and the EHRPD network identifier is modified according to the activation state of the 4G service, so as to ensure that the terminal is modified, restarted, switched flight mode, or the terminal replaces the service card, and the modified The EHRPD network logo is still in effect.
