Description

Network connection method, network connection device, electronic equipment and computer readable storage medium

Technical Field

The present application relates to the field of electronic technologies, and in particular, to a network connection method, a network connection device, an electronic device, and a computer readable storage medium.

Background

With the progress of social production and people's life, people have increasingly high demands on communication quality. Among the many communication modes, conversation is one of the most common and important modes. Typically, a calling party triggers a call connection by dialing the telephone number of the called party. If the called party is not connected, namely the calling party can not receive the incoming call or can not normally connect the call after receiving the incoming call when dialing the telephone number of the called party, the call can not be normally conducted.

In the call service, the called party is one of the problems with highest priority, and operators in many areas can open the electric leakage reminding service. If the calling party dials the telephone of the called party and fails to be connected, the operator server automatically sends an electric leakage reminding short message to the called party to inform the user of the called party that a call fails to be connected. Thus, when the called party is not available, the user can know that the call is missed.

However, if the caller constantly dials the call of the callee, the call may fail in the period of time, and the callee continuously receives the leakage reminding short message, resulting in poor user experience.

Disclosure of Invention

The application provides a network connection method, a network connection device, a network connection chip, an electronic device, a computer readable storage medium and a computer program product, which can improve the success rate of a called party and the user experience.

In a first aspect, a network connection method is provided, including: acquiring a short message transmission mode of a first electric leakage reminding short message; acquiring a current call residence system, wherein the current call residence system is used for representing a communication system where a call service resides at the current moment; and executing a target strategy according to the short message transmission mode and the current call residence mode, wherein the target strategy is used for re-registering the call service.

The terminal equipment selects a network mode capable of establishing a call service to re-register the call service according to the short message transmission mode of the first electric leakage reminding short message and the current call residence mode, so that the network fault is automatically repaired, and the condition that continuous called is not enabled due to the network fault is avoided. When the terminal equipment is called again as a called party, the call can be normally established, the success rate of call connection is improved, the call quality is improved, and the user experience is further improved.

In some possible implementation manners, the short message transmission manner includes a short message type of the first electric leakage reminding short message and a short message receiving system of the first electric leakage reminding short message, where the short message receiving system is used for representing a communication system for receiving the first electric leakage reminding short message.

The terminal equipment selects a network mode capable of establishing a call service to re-register the call service according to the short message type, the short message receiving mode and the current call residence mode of the first electric leakage reminding short message, so that the network fault is automatically repaired, and the condition that continuous called is not communicated due to the network fault is avoided. When the terminal equipment is called again as a called party, the call can be normally established, the success rate of call connection is improved, the call quality is improved, and the user experience is further improved.

In some possible implementations, when the short message type is a non-access stratum (non access stratum, NAS) short message, the short message receiving system is a New Radio (NR), and the current call residence system is NR, the target policy includes: re-registers with the IP multimedia subsystem (IP Multimedia Subsystem, IMS) over the NR network.

When the short message type is NAS short message, the short message receiving mode is NR, and the current call residence mode is NR, the NR mode of the fifth generation mobile communication technology (5th generation mobile communication technology,5G) realizes communication service by registering IMS service to IMS, and the called party is not communicated at the moment, which indicates that the IMS is possibly abnormal, so that the terminal equipment can register IMS service to the IMS again on an NR network to repair the fault. When called again, the call can be established normally. At this time, the call service of the terminal device still uses the NR system, and the communication quality is higher than that of the fourth generation mobile communication technology (4h generation mobile communication technology,4G).

In some possible implementations, after re-registering with the IMS on the NR network, the target policy further includes:

and when the second leakage reminding short message is received, closing an independent networking (SA) network.

The above procedure may also be described as a procedure employing a two-stage self-healing policy, one stage of self-healing policy being re-registering with the IMS over the NR network; if the primary self-healing strategy cannot solve the problem that the called party is not enabled, namely, after IMS service is registered on the NR network again, the terminal equipment receives the electric leakage reminding short message, the secondary self-healing strategy is continuously adopted, namely, the SA network is closed to roll back the network of the call service. The two-stage self-healing strategy can further improve the success rate of network restoration, thereby improving the success rate of the called party and improving the user experience.

In some possible implementations, when the short message type is NAS short message, the short message receiving system is NR, and the current call residence system is NR, the target policy is: the SA network is shut down. Call traffic is also rolled back from the 5G network to the 4G network without first registering IMS services with the IMS over the NR network.

The terminal equipment directly backs the call service from the 5G network to the 4G network, compared with the mode of adopting the two-stage self-healing strategy, the network can be backed off when the first leakage reminding short message is identified, the problem of low network repairing efficiency caused by the condition that the IMS service cannot be repaired again on the NR network is avoided, the network is backed off without waiting for receiving the second leakage reminding short message, the network where the call service resides can be repaired at the highest probability at the first time, the called success rate is improved, the network repairing flow is reduced, the network repairing time is shortened, and the user experience is improved.

In some possible implementations, when the short message type is NAS short message, the short message receiving system is long term evolution (longterm evolution, LTE) and the current call residence system is LTE, the target policies include: re-registering with the IMS over the LTE network.

Since the LTE standard can also implement communication services by registering IMS services with the IMS, the terminal device can re-register IMS services with the IMS on the LTE network to attempt to repair the network failure. Re-registering IMS services with the IMS over the LTE network may repair previous network failures, and call may be established normally when called again. At this time, the communication service of the terminal device still uses the LTE system of 4G, and the communication quality is higher than the systems of the second generation mobile communication technology (2thgeneration mobile communication technology,2G) and the third generation mobile communication technology (3th generationmobile communication technology,3G).

In some possible implementations, after re-registering with the IMS over the LTE network, the target policy further includes: and when the second leakage reminding short message is received, the IMS service is closed.

The above procedure may also be described as a procedure employing a two-level self-healing policy, where the one-level self-healing policy is to re-register IMS services with IMS on the LTE network, i.e. to preferentially re-register IMS services with IMS on the 4G LTE network; if the first-level self-healing strategy cannot solve the problem that the called party is not enabled, namely, after the IMS service is registered with the IMS on the LTE network again, the terminal equipment receives the electric leakage reminding short message, the second-level self-healing strategy is continuously adopted, namely, the network of the IMS service for returning to the call service is closed. The two-stage self-healing strategy can further improve the success rate of network restoration, thereby improving the success rate of the called party and improving the user experience.

In some possible implementations, when the short message type is NAS short message, the short message receiving system is LTE, and the current call residence system is LTE, the target policy is: the IMS service is turned off. The call service is directly rolled back to the next 2G or 3G network to realize the call service.

Network rollback can address most network failures. After the network is backed, the call service can use a 2G or 3G network. The terminal equipment directly backs the call service from the 4G network to the 2G or 3G network, compared with the mode of adopting the two-stage self-healing strategy, the network can be backed off when the first leakage reminding short message is identified, the problem of low network repairing efficiency caused by the condition that the IMS service is registered again on the LTE network to the IMS service and the network failure cannot be repaired is avoided, the network is backed off without waiting for receiving the second leakage reminding short message, the network where the call service resides can be repaired at the highest probability at the first time, the called success rate is improved, the network repairing flow is reduced, the network repairing time is shortened, and the user experience is improved.

In some possible implementations, executing the target policy according to the short message transmission mode and the current call residence mode includes: and executing a target strategy according to the short message transmission mode, the current call residence mode and the screen state.

If the screen state is a bright screen state, the fact that the user is watching the screen is possibly indicated, the terminal equipment is in a used state, and the terminal equipment can directly fall back to the network to ensure that the call service is recovered with the highest probability preferentially, so that the user experience is not affected; if the screen is in the off-screen state, the terminal equipment may be in an unused state, at this time, the terminal equipment can re-register the network where the current call service resides, and then if the network failure cannot be repaired, the network is returned, and the user use is not affected.

In some possible implementations, when the short message type is an IMS short message, the short message receiving system is NR, the current call residence system is NR, and the screen state is a bright screen state, the target policy is: the SA network is shut down.

When the short message type is IMS short message, the short message receiving system is NR, the current call residence system is NR, and the screen state is the bright screen state, under the condition that the called party is not connected, the SA network is presumed to be faulty, and the terminal equipment can close the SA network. At this time, if the network supports a networking mode of a non-independent Networking (NSA), the terminal device may switch from the networking mode of the SA network to the networking mode of the NAS network, and the call service may also be rolled back from the 5G network to the 4G network, and the sms service may also be rolled back to the 4G network. Alternatively, the data traffic may remain with the 5G network. Network rollback can address most network failures. If the network does not support the networking mode of NSA, the terminal device may switch to the 4G network. Thus, the call service can be realized by directly using the next-stage 4G network. The method can repair the network where the call service resides at the first time with the highest probability in the bright screen state, does not influence the use of the user, reduces the flow of network repair while improving the success rate of the called party, shortens the time of network repair, and improves the user experience.

In some possible implementations, when the short message type is an IMS short message, the short message receiving system is NR, the current call residence system is NR, and the screen state is an off-screen state, the target policy includes: re-registers with the IMS over the NR network.

In the off-screen state, the terminal device may be in an unused state, and the terminal device may re-register IMS services with the IMS in the NR network to attempt to repair the failure of the NR network. In some cases, re-registering the IMS service with the IMS at the NR network may repair the previous network failure, and call may be established normally when called again. At this time, the call service of the terminal device still uses the 5G NR system, and the communication quality is higher than that of the 4G system.

In some possible implementations, after re-registering with the IMS on the NR network, the target policy further includes: and when the second electric leakage reminding short message is received, closing the SA network.

If the terminal equipment receives the second leakage reminding short message after the NR network registers the IMS service with the IMS again, the called party is still not enabled. At this time, the terminal device may consider that registering the IMS service again with the IMS in the NR network cannot repair the network failure, and may shut down the SA network. At this time, if the network supports the networking mode of NSA, the terminal device can switch from the networking mode of SA network to the networking mode of NAS network, and the call service is also rolled back from 5G network to 4G network. Thus, the call service can be realized by using the next-stage 4G network instead of the 5G network which cannot be repaired. After the network is backed, the call service can use the 4G network. Alternatively, the data traffic may remain with the 5G network. If the network does not support the networking mode of NSA, the network is directly backed off to the 4G network. The above procedure may also be described as a procedure employing a two-stage self-healing policy, one of which is to re-register IMS services with the IMS in the NR network; if the primary self-healing strategy cannot solve the problem that the called party is not through, namely, after the NR network is re-registered, the terminal equipment receives the electric leakage reminding short message, the secondary self-healing strategy is continuously adopted, namely, the SA network is closed to back off the network of the call service. By adopting the two-stage self-healing strategy, the success rate of network restoration can be further improved in the screen-off state, so that the success rate of a called party is improved, and the use of a user is not influenced.

In some possible implementations, when the short message type is an IMS short message, the short message receiving system is LTE, and the current call residence system is LTE, the target policy includes: re-registering with the IMS over the LTE network. The terminal device may re-register IMS services with the IMS over the LTE network in an attempt to repair the network failure.

In some possible implementations, the target policy is: when the Nth leakage reminding short message is received, registering to the IMS on the LTE network again; the N-th electric leakage reminding short message is a received N-th electric leakage reminding short message, and N is an integer larger than 1.

The terminal equipment can not process the first electric leakage reminding short message when receiving the first electric leakage reminding short message, and wait for receiving other electric leakage reminding short messages, wherein the other electric leakage reminding short messages can be second electric leakage reminding short messages, namely the second electric leakage reminding short messages; the method can also be a third time, a fourth time and the like of the received electric leakage reminding short message, namely, when the electric leakage reminding short message is received for the first time, the processing is not performed, because the short message type is an IMS short message, the short message receiving mode is LTE and the current call residence mode is LTE, if the called party fails to indicate that the incoming call is not accessed through an IMS domain, and the incoming call is not accessed from a CS domain, probably because of short network abnormality, the electric leakage reminding short message can be automatically repaired without processing, the terminal equipment can execute the self-healing strategy again when the electric leakage reminding short message is received for a plurality of times (namely, the Nth electric leakage reminding short message is received, and N is more than or equal to two), invalid re-registration flow can be avoided, and resources of the terminal equipment are saved.

In some possible implementations, the target policy is: and when the Nth leakage reminding short message is received and the screen state is the bright screen state, registering to the IMS on the LTE network again.

When the terminal receives the Nth leakage reminding short message, the network is not restored by itself, if the terminal is in a bright screen state at the moment, and the user is possibly using the terminal equipment, the prior network fault can be repaired by registering IMS service to IMS through LTE network, and when the terminal is called again, the call can be normally established. Therefore, the user can not feel the disconnection, and the use of the user can not be influenced. At this time, the call service of the terminal device still uses the LTE system of 4G, and compared with the systems of 2G and 3G, the communication quality is higher.

And when the Nth electric leakage reminding short message is received and the screen state is the screen-off state, the registration is initiated to the core network again, and the registration is carried out to the IMS in the LTE network again.

When the terminal receives the Nth leakage reminding short message, the network is not recovered by itself, and if the network is in a screen-off state at the moment, the user is not likely to use the terminal equipment. At this time, the registration can be directly restarted to the core network (i.e. one attach connection is triggered), then the IMS service is newly registered to the IMS in the LTE network, and the process not only re-executes the NAS flow, but also re-executes the session initiation protocol (session initiation protocol, SIP) flow, which is equivalent to switching to the flight mode, re-registering the very trusted network and registering to the IMS in the LTE network. The method has the advantages that registration is initiated to the core network again, IMS service is registered to the IMS in the LTE network again, network faults under more conditions can be repaired compared with the condition that the IMS service is registered to the IMS in the LTE network only again, network faults can be guaranteed to be repaired to the greatest extent when a user does not use terminal equipment, the called success rate is improved, and the use of the user is not affected.

In some possible implementations, when the short message type is a circuit switched CS short message, the short message receiving system is a network system of the second generation mobile communication 2G/the third generation mobile communication 3G, and the current call residence system is LTE, the target policies include: re-registering with the IMS over the LTE network.

It may be considered that the IMS has failed at this time, and the terminal device may re-register IMS services with the IMS on the LTE network of 4G to repair the network failure.

In some possible implementations, the target policy is: when the screen state is the bright screen state, registering to the IMS on the LTE network again; and when the screen state is the off-screen state, re-initiating registration to the core network and re-registering to the IMS on the LTE network.

When the screen is in the off-screen state, which indicates that the user may not use the terminal device at this time, the terminal device may initiate registration with the core network again (i.e. trigger an attach connection), and register IMS services with the IMS in the LTE network to repair network failures. And the registration is initiated to the core network again, and network faults under more conditions can be repaired when the LTE network is registered to the IMS only compared with the registration to the IMS only again, so that the network faults can be repaired to the greatest extent when the user does not use the terminal equipment, the called success rate is improved, and the use of the user is not influenced. When the screen is in a bright screen state, the user is possibly using the terminal equipment, and the terminal equipment can only register IMS service with the IMS in the LTE network to repair network faults, but can not re-register the core network, so that the user can not perceive the disconnection of the network, and the use of the user can not be influenced.

In some possible implementation manners, the obtaining manner of the short message type of the first electric leakage reminding short message includes: if the transmission channel of the first electric leakage reminding short message is a channel of the SIP message, determining the type of the short message as an IMS short message; if the transmission channel of the first electric leakage reminding short message is a channel of a non-access stratum (NAS) message and the resident network type icon is 2G or 3G when the first electric leakage reminding short message is received, determining that the short message type is CS short message; if the transmission channel of the first electric leakage reminding short message is a channel of the NAS message and the resident network type icon when the first electric leakage reminding short message is not 2G or 3G, determining that the short message type is the NAS short message.

If the transmission channel of the first electric leakage reminding short message is not a channel of the SIP message and is transmitted through a channel of the 2G or 3G NAS message, the short message type can be determined as the CS short message; if the transmission channel of the first leakage reminding short message is the channel transmission of the 4G or 5G NAS message, the short message type can be determined to be the NAS short message. Optionally, the terminal device may determine the short message type according to a network injection type icon (RAT) of the terminal device when receiving the first leakage reminding short message. If the network-resident icon of the terminal equipment is displayed as 2G or 3G when the first electric leakage reminding short message is received, determining the type of the short message as a CS short message; if the network-resident icons of the terminal equipment display 2G and 3G or 4G and 5G when the first electric leakage reminding short message is received, the short message type can be determined to be NAS short message. The accuracy of acquiring the short message type by adopting the mode is high.

In some possible implementations, obtaining a short message transmission mode of the first electric leakage reminding short message includes: receiving a short message to be detected; determining whether the short message to be detected is a first electric leakage reminding short message or not according to the short message content of the short message to be detected and the sender identification of the short message to be detected; and if the short message to be detected is the first electric leakage reminding short message, acquiring a short message transmission mode of the first electric leakage reminding short message.

After receiving the short message, the terminal equipment can identify the short message, so as to determine whether the short message is an electric leakage reminding short message issued by an operator. In some embodiments, the terminal device may preset a leakage number, i.e. the number of the operator (sender identification), and a keyword capable of characterizing the leakage alert. After the keywords of the short message are identified, the short message is compared with preset keywords, and if the content of the short message comprises the preset keywords, the short message can be determined to be the electric leakage reminding short message. If the content of the short message does not or does not completely include the preset keyword, the short message is determined not to be the electric leakage reminding short message. The preset missing point number and the preset keyword can also be updated by refreshing the version or accessing the cloud server. The method can accurately identify the electric leakage reminding short message, thereby accurately and timely triggering and executing the self-healing strategy of the network and improving the success rate of the called party.

In a second aspect, there is provided a network connection device comprising: the electric leakage reminding detection module and the network searching module; the electric leakage reminding detection module is used for identifying the first electric leakage reminding short message and acquiring a short message transmission mode of the first electric leakage reminding short message; the network searching module is used for acquiring a current call residence system, wherein the current call residence system is used for representing a communication system where a call service resides at the current moment; the electric leakage reminding detection module is used for executing a target strategy according to the short message transmission mode and the current conversation residence mode; and the network searching module is used for re-registering the call service according to the target strategy.

In some possible implementations, the apparatus further includes a unit composed of software and/or hardware, where the unit is configured to perform any one of the methods in the technical solutions of the first aspect.

In a third aspect, there is provided an electronic device, comprising: a processor, a memory, and an interface; the processor, the memory and the interface cooperate with each other such that the electronic device performs any one of the methods of the technical solutions of the first aspect.

For easy understanding, the following embodiments of the present application will take a terminal device having a structure shown in fig. 1 and fig. 2 as an example, and specifically describe a network connection method provided in the embodiments of the present application with reference to the accompanying drawings and application scenarios.

In the call service, the called party is one of the problems with highest priority, and operators in many areas can open the electric leakage reminding service. If the calling party dials the telephone of the called party and fails to be connected, the operator server automatically sends an electric leakage reminding short message to the called party to inform the user of the called party that a call fails to be connected. Therefore, even when the called party is not available, the user can know that the call is missed. However, if the caller constantly dials the call of the callee, the call may fail during the period of time, and the callee continuously receives the leakage reminding short message. This can lead to user failure as a handset and poor user experience.

According to the call connection method, when the terminal equipment receives the electric leakage reminding short message, the call service can be registered again according to the short message transmission mode and the communication mode where the call service resides, so that the network self-healing is realized. The terminal device may re-register the communication system in which the previous call service resides, or may re-register other communication systems. For example, if the communication format in which the previous call service resides is a 5G format, the terminal device may return the call service to a 4G format if the called party is not available; if the communication system where the call service resides is a 4G system, the terminal device can return the call service to a 2G or 3G system under the condition that the called party is not connected. The terminal equipment can also register the communication system before the terminal equipment is registered again, and when the leakage reminding short message is received again, the communication system where the call service resides is returned again. The terminal device automatically restores the network fault by re-registering the call service, so as to avoid the condition that the continuous called party is not enabled due to the network fault. When the called party is called again, the call can be normally established, the success rate of call connection is improved, the call quality is improved, and further the user experience is improved.

Fig. 3 is a flowchart of an example of a network connection method according to an embodiment of the present application. The method may include:

s301, acquiring a short message transmission mode of the first electric leakage reminding short message.

After receiving the short message, the terminal equipment can identify the short message, so as to determine whether the short message is an electric leakage reminding short message issued by an operator. In some embodiments, the terminal device may preset a leakage number, i.e. the number of the operator, and a keyword capable of characterizing the leakage alert. After the keywords of the short message are identified, the short message is compared with preset keywords, and if the content of the short message comprises the preset keywords, the short message can be determined to be the electric leakage reminding short message. If the content of the short message does not or does not completely include the preset keyword, the short message is determined not to be the electric leakage reminding short message. The preset missing point number and the preset keyword can also be updated by refreshing the version or accessing the cloud server. The method can accurately identify the electric leakage reminding short message, thereby accurately and timely triggering and executing the self-healing strategy of the network and improving the success rate of the called party.

Optionally, the terminal device may identify keywords in the content of the short message, and when it is identified that keywords such as "missed call", "missed call" and "incoming call" exist in the text of the short message, and the keywords include keywords of time, for example, several points and several minutes, it may be determined that the short message is a leakage reminding short message; optionally, the terminal device may also combine the identified keyword with the sender to determine whether the message is a leakage reminding short message, for example, when keywords such as "missed call", "incoming call" exist in the text of the short message, and the phone number of the sender of the short message is an operator, the short message may be determined to be the leakage reminding short message; optionally, the terminal device may further combine the identified keyword with the sender identifier to determine whether the message is a leakage reminding short message, for example, when keywords such as "missed call", "incoming call" exist in the text of the short message, and the keywords include time, and when the sender of the short message is the number of the operator, the short message may be determined to be the leakage reminding short message. The mode of determining whether the short message is the electric leakage reminding short message is not limited, and the embodiment of the application is only required if the electric leakage reminding short message can be identified.

For example, the terminal device receives the short message: carrier a wakes up you: user 18600000000 calls you once at 2018/8/15:17, you can press the talk key to dial back. The terminal equipment carries out keyword recognition aiming at the short message, and the recognition comprises: the operators A, 2018/8/15:17 and the incoming call keywords can determine that the short message is the electric leakage reminding short message.

When the terminal equipment recognizes that the first electric leakage reminding short message is received, a short message transmission mode of the first electric leakage reminding short message can be obtained. The first leakage reminding short message may be a leakage reminding short message received for the first time. The short message transmission mode can represent the current network state, and if the terminal equipment can receive the first electric leakage reminding short message, the network mode for the first electric leakage reminding short message transmission can be indicated to be normally communicated.

Optionally, the short message transmission mode may include a short message type of the first electric leakage reminding short message, and the short message type may include: NAS messages, IP multimedia subsystem (IP Multimedia Subsystem) messages, and Circuit Switched (CS) messages. The short message transmission manner may further include a short message receiving system of the first leakage reminding short message, for example, including a 5G system (for example, NR), a 4G system (for example, LTE), a 3G system and a 2G system (for example, GSM, CDMA, WCDMA).

Optionally, the terminal device may obtain a short message type and a short message receiving format reported to the application layer by the short message receiving module.

S302, acquiring a current call residence system, wherein the current call residence system is used for representing a communication system where a call service resides at the current moment.

The terminal equipment can acquire the communication system registered by the call service at the current moment, namely, acquire the current call residence system. The current call resident mode may be any one of 2G, 3G, 4G and 5G.

Optionally, the terminal device may acquire a current call residence format that may be reported to the application layer by the network searching module.

S303, executing a target strategy according to the short message transmission mode and the current call residence mode, wherein the target strategy is used for re-registering the call service.

The terminal device can receive the first leakage reminding short message, but fails to establish a call, and the network mode corresponding to the short message transmission mode of the first leakage reminding short message is indicated to be in a normal state, and the network mode of the call service may have a fault, and the call service may be re-registered once according to the current call residence mode, or the call service different from the current call residence mode may be re-registered once according to the network mode without the fault indicated by the short message transmission mode.

In the embodiment shown in fig. 3, the terminal device selects the network mode capable of establishing the call service to re-register the call service according to the short message transmission mode of the first electric leakage reminding short message and the current call residence mode, so as to automatically repair the network fault and avoid the condition that the continuous called party is not enabled due to the network fault. When the terminal equipment is called again as a called party, the call can be normally established, the success rate of call connection is improved, the call quality is improved, and the user experience is further improved.

The short message type in the method can represent a message channel for transmitting the short message, and the terminal equipment can determine the short message type according to the message channel for transmitting the short message of the first electric leakage reminding short message. When the transmission channel of the first leakage reminding short message is a channel of a session initiation protocol (session initiation protocol, SIP) message, the type of the short message can be determined to be an IMS short message.

If the transmission channel of the first electric leakage reminding short message is not a channel of the SIP message and is transmitted through a channel of the 2G or 3G NAS message, the short message type can be determined as the CS short message; if the transmission channel of the first leakage reminding short message is the channel transmission of the 4G or 5G NAS message, the short message type can be determined to be the NAS short message.

Optionally, the terminal device may determine the short message type according to a network injection type icon (RAT) of the terminal device when receiving the first leakage reminding short message. If the network-resident icon of the terminal equipment is displayed as 2G or 3G when the first electric leakage reminding short message is received, determining the type of the short message as a CS short message; if the network-resident icons of the terminal equipment display 2G and 3G or 4G and 5G when the first electric leakage reminding short message is received, the short message type can be determined to be NAS short message. The accuracy of acquiring the short message type by adopting the mode is high.

The specific process of how the terminal device executes the corresponding target policy according to the short message type, the short message receiving system and the current call residence system will be described in detail below.

When the short message type is NAS short message, the short message receiving mode is NR, and the current call residence mode is NR, the 5G NR mode realizes communication service by registering with IMS, and the called party is not communicated at this time, which indicates that the IMS is possibly abnormal, so that the terminal equipment can register IMS service with the IMS on the NR network again to repair the fault. When called again, the call can be established normally. At this time, the call service of the terminal device still uses the NR system, and the communication quality is higher than that of the 4G system.

Optionally, if the terminal device receives the second leakage reminding short message again after registering the IMS service with the IMS on the NR network again, this indicates that the called party is still not connected. At this time, the terminal device may consider that registering IMS services again with the IMS over the NR network cannot repair the network failure, and may shut down the SA network. If the network supports the networking mode of NSA, the terminal equipment can switch from the networking mode of SA network to the networking mode of NAS network, and the call service is backed to 4G network from 5G network. Thus, the call service can be realized by using the next-stage 4G network instead of the 5G network which cannot be repaired. After the network is backed, the call service can use the 4G network. Alternatively, the data traffic may remain with the 5G network. If the network does not support the networking mode of NSA, after the SA network is closed, the call service and the data service are switched to the 4G network. The above procedure may also be described as a procedure employing a two-stage self-healing policy, one stage of self-healing policy being re-registering with the IMS over the NR network; if the primary self-healing strategy cannot solve the problem that the called party is not enabled, namely, after IMS service is registered on the NR network again, the terminal equipment receives the electric leakage reminding short message, the secondary self-healing strategy is continuously adopted, namely, the SA network is closed to roll back the network of the call service. The two-stage self-healing strategy can further improve the success rate of network restoration, thereby improving the success rate of the called party and improving the user experience. The manner of identifying the second leakage reminding short message by the terminal device can be referred to the foregoing manner of identifying the first leakage reminding short message, which is not described herein again. Alternatively, the SA network may be turned off here for a period of time, e.g., 5 minutes, 10 minutes, without being turned off all the time.

When the terminal equipment receives the first leakage reminding short message, if the short message type is NAS short message, the short message receiving system is NR, and the current call residence system is NR, the terminal equipment can also directly close the SA network. That is, the terminal device may switch directly from the networking mode of the SA network to the networking mode of the NAS network, and the call service is also rolled back from the 5G network to the 4G network, without first registering the IMS service with the IMS on the NR network. Network rollback can address most network failures. After the network is backed, the call service can use the 4G network. The terminal equipment directly backs the call service from the 5G network to the 4G network, compared with the mode of adopting the two-stage self-healing strategy, the network can be backed off when the first leakage reminding short message is identified, the problem of low network repairing efficiency caused by the condition that the IMS service is registered again on the NR network to the IMS service and network faults cannot be repaired is solved, the network is backed off without waiting for receiving the second leakage reminding short message, the network where the call service resides can be repaired at the highest probability at the first time, the called success rate is improved, the network repairing flow is reduced, the network repairing time is shortened, and the user experience is improved.

When the short message type is NAS short message, the short message receiving mode is LTE and the current call residence mode is LTE, the terminal equipment can register IMS service to IMS again on the LTE network to try to repair the network fault because the LTE mode can also register IMS service to realize communication service. In some cases, re-registering IMS services with the IMS over the LTE network may repair previous network failures, and call may be established normally when called again. At this time, the call service of the terminal device still uses the LTE system of 4G, and compared with the systems of 2G and 3G, the communication quality is higher.

Optionally, if the terminal device receives the second leakage reminding short message again after registering with the IMS on the LTE network again, this indicates that the called party is still not communicating. At this time, the terminal device may consider that registering the IMS service again with the IMS over the LTE network cannot repair the network failure, and may close the IMS service. Since voice service in LTE standard of 4G can register IMS or register CS domain to realize communication service, when IMS service of terminal device is closed, it becomes CS only, and call service is rolled back (dropped) from 4G network to 2G or 3G network, which may be called CS fallback (CSFB). When the call service is performed, the terminal device can not use the 4G network which cannot be repaired to realize the call service, but fall back to use the 2G or 3G network of the next stage to realize the call service. Network rollback can address most network failures. After the network is backed, the call service can use a 2G or 3G network. The above procedure may also be described as a procedure employing a two-level self-healing policy, where the one-level self-healing policy is to re-register IMS services with IMS on the LTE network, i.e. to preferentially re-register IMS services with IMS on the 4G LTE network; if the first-level self-healing strategy cannot solve the problem that the called party is not enabled, namely, after the IMS service is registered with the IMS on the LTE network again, the terminal equipment receives the electric leakage reminding short message, the second-level self-healing strategy is continuously adopted, namely, the network of the IMS service for returning to the call service is closed. The two-stage self-healing strategy can further improve the success rate of network restoration, thereby improving the success rate of the called party and improving the user experience. The manner of identifying the second leakage reminding short message by the terminal device can be referred to the foregoing manner of identifying the first leakage reminding short message, which is not described herein again. Alternatively, the IMS service may be turned off here for a period of time, e.g. 5 minutes, 10 minutes, without being turned off all the time.

When the terminal equipment receives the first leakage reminding short message, if the short message type is NAS short message, the short message receiving system is LTE, and the current call residence system is LTE, the terminal equipment can directly close the IMS service without registering the IMS service on the LTE network again, and fall back to the next-stage 2G or 3G network to realize the call service. Network rollback can address most network failures. After the network is backed, the call service can use a 2G or 3G network. The terminal equipment directly backs the call service from the 4G network to the 2G or 3G network, compared with the mode of adopting the two-stage self-healing strategy, the network can be backed off when the first leakage reminding short message is identified, the problem of low network repairing efficiency caused by the condition that the IMS service is registered again on the LTE network to the IMS service and the network failure cannot be repaired is avoided, the network is backed off without waiting for receiving the second leakage reminding short message, the network where the call service resides can be repaired at the highest probability at the first time, the called success rate is improved, the network repairing flow is reduced, the network repairing time is shortened, and the user experience is improved. Alternatively, the IMS service may be turned off here for a period of time, e.g. 5 minutes, 10 minutes, without being turned off all the time.

In some cases, the terminal device may also determine what target policy to execute in conjunction with the screen status. If the screen state is a bright screen state, the fact that the user is watching the screen is possibly indicated, the terminal equipment is in a used state, and the terminal equipment can directly fall back to the network to ensure that the call service is recovered with the highest probability preferentially, so that the user experience is not affected; if the screen is in the off-screen state, the terminal equipment may be in an unused state, at this time, the terminal equipment can re-register the network where the current call service resides, and then if the network failure cannot be repaired, the network is returned, and the user use is not affected.

Specifically, when the short message type is an IMS short message, the short message receiving system is NR, the current call residence system is NR, and the screen state is a bright screen state, it is presumed that the SA network is faulty in the case that the called party is not connected, and the terminal device may close the SA network. At this time, if the network supports the NSA networking mode, the terminal device may switch from the SA networking mode to the NAS networking mode, and the call service may also fall back from the 5G network to the 4G network, and the sms service may also fall back to the 4G network. Alternatively, the data traffic may remain with the 5G network. Network rollback can address most network failures. If the network does not support the networking mode of NSA, the terminal device may switch to the 4G network. Thus, the call service can be realized by directly using the next-stage 4G network. The method can repair the network where the call service resides at the first time with the highest probability in the bright screen state, does not influence the use of the user, reduces the flow of network repair while improving the success rate of the called party, shortens the time of network repair, and improves the user experience. Alternatively, the SA network may be turned off for a period of time, e.g., 5 minutes, 10 minutes, without being turned off all the time.

If the screen is in the off-screen state, the terminal device may be in an unused state, at which point the terminal device may re-register the IMS service with the IMS in the NR network to attempt to repair the failure of the NR network. In some cases, re-registering the IMS service with the IMS at the NR network may repair the previous network failure, and call may be established normally when called again. At this time, the call service of the terminal device still uses the 5G NR system, and the communication quality is higher than that of the 4G system. Optionally, if the terminal device receives the second leakage reminding short message again after the NR network registers the IMS service with the IMS again, the called party is still not communicated. At this time, the terminal device may consider that registering the IMS service again with the IMS in the NR network cannot repair the network failure, and may shut down the SA network. At this time, if the network supports the networking mode of NSA, the terminal device can switch from the networking mode of SA network to the networking mode of NAS network, and the call service is also rolled back from 5G network to 4G network. Thus, the call service can be realized by using the next-stage 4G network instead of the 5G network which cannot be repaired. After the network is backed, the call service can use the 4G network. Alternatively, the data traffic may remain with the 5G network. If the network does not support the networking mode of NSA, the network is directly backed off to the 4G network. The above procedure may also be described as a procedure employing a two-stage self-healing policy, one of which is to re-register IMS services with the IMS in the NR network; if the primary self-healing strategy cannot solve the problem that the called party is not through, namely, after the NR network is re-registered, the terminal equipment receives the electric leakage reminding short message, the secondary self-healing strategy is continuously adopted, namely, the SA network is closed to back off the network of the call service. By adopting the two-stage self-healing strategy, the success rate of network restoration can be further improved in the screen-off state, so that the success rate of a called party is improved, and the use of a user is not influenced. Alternatively, the SA network may be turned off for a period of time, e.g., 5 minutes, 10 minutes, without being turned off all the time.

When the short message type is IMS short message, the short message receiving mode is LTE and the current call residence mode is LTE, the LTE mode can also realize communication service by registering IMS service with IMS, so the terminal equipment can register IMS service with IMS on the LTE network again to try to repair the network fault.

Optionally, the terminal device may not process the first leakage reminding short message when receiving the first leakage reminding short message, and wait for receiving other leakage reminding short messages, where the other leakage reminding short messages may be second leakage reminding short messages, that is, the second leakage reminding short messages received; the method can also be a third time, a fourth time and the like of the received electric leakage reminding short message, namely, when the electric leakage reminding short message is received for the first time, the processing is not performed, because the short message type is an IMS short message, the short message receiving mode is LTE and the current call residence mode is LTE, if the called party fails to indicate that the incoming call is not accessed through an IMS domain, and the incoming call is not accessed from a CS domain, probably because of short network abnormality, the electric leakage reminding short message can be automatically repaired without processing, the terminal equipment can execute the self-healing strategy again when the electric leakage reminding short message is received for a plurality of times (namely, the Nth electric leakage reminding short message is received, and N is more than or equal to two), invalid re-registration flow can be avoided, and resources of the terminal equipment are saved.

When the short message type is a circuit switched (circuit switched domain, CS) short message, the short message receiving system is a network system (such as GSM, WCDMA, etc.) of 2G or 3G, and the current call residence system is LTE, the call service resides on the LTE network of 4G, but the short message type is a CS short message, which can be considered that the IMS is faulty at this time, and the terminal device can reinject the IMS service registered with the IMS on the LTE network of 4G to repair the network fault. Optionally, when the screen is in the off-screen state, which indicates that the user may not use the terminal device at this time, the terminal device may re-initiate registration with the core network (i.e. trigger an attach connection), and re-register IMS services with the IMS in the LTE network to repair the network failure. And the registration is initiated to the core network again, and network faults under more conditions can be repaired when the LTE network is registered to the IMS only compared with the registration to the IMS only again, so that the network faults can be repaired to the greatest extent when the user does not use the terminal equipment, the called success rate is improved, and the use of the user is not influenced. When the screen is in a bright screen state, the user is possibly using the terminal equipment, and the terminal equipment can only register IMS service with the IMS in the LTE network to repair network faults, but can not re-register the core network, so that the user can not perceive the disconnection of the network, and the use of the user can not be influenced.

For a clearer description of the conditions for execution of the target policy, reference may be made to the correspondence relationships shown in table 1.

In the technical solution provided in the embodiment of the present application, by adding a leakage reminding detection module to an application layer, a leakage reminding short message is identified, so as to trigger a re-registration process, an interactive chart may be shown in fig. 5, including:

When incoming call is received again, the terminal device can be used as a called party to establish call connection with a calling party.

The order of the steps is not limited, and for example, the order of S502, S503, S504, S505, and S506 is not limited, so long as the method can be implemented before S510. In addition, the steps S506 and S508 may be implemented through the same step or implemented separately, for example, the short message receiving module reports the content and the type of the received short message to the application layer, and broadcasts the short message at the application layer, the short message display module of the application layer displays the short message according to the content, and the electric leakage reminding detection module of the application layer identifies the content of the short message and determines whether the short message is an electric leakage reminding short message. The execution order of S508 and S507 is not limited.

The call processing module, the sms receiving module and the call processing module may be software modules located in another Modem different from the leakage reminding detection module, which is not limited in this embodiment of the present application.

Optionally, the above process of determining the type of the short message may be that in an Application Processor (AP) of the terminal device, the leakage reminding detection module determines the type of the short message according to whether the bottom layer reports an IMS short message or not, if not, according to a system of receiving the leakage reminding short message (i.e. a network residence icon when receiving the leakage reminding short message). If the network resident icon is 2G or 3G, the network resident icon is determined to be a CS short message, and if the network resident icon is not 2G and 3G but 4G or 5G, the short message type can be determined to be a NAS short message.

Optionally, the above process of determining the type of the short message may also be that the terminal device determines the type of the short message through a Modem (Modem). The Modem reports the short message type according to the channel of the electric leakage reminding short message, and if the electric leakage reminding short message is coming through the SIP message, the short message type is determined to be the IMS short message; if the NAS message comes through 4G or 5G, determining the type of the short message as the NAS short message; if the message comes in through the NAS message of 2G or 3G, the message is determined to be the CS message. Thus, the AP does not need to judge the type of the short message.
