Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

The embodiments of the present invention described below are applicable to an operating environment such as that shown in fig. 1. As shown in fig. 1, the mobile terminal 100 accesses the network 200 through a random access mechanism to perform data communication or interaction with the network 200. The mobile terminal 100 may be any terminal device having a radio frequency channel, such as a smart phone, a tablet computer, a PDA (Personal Digital Assistant), and a vehicle-mounted computer, and the network 200 may be a wireless network, but is not limited to a 2G/3G/4G network.

The mobile terminal 100 is provided with a plurality of radio frequency paths, and the mobile terminal sends out modulation signals through the radio frequency paths, tries to access the network, and establishes basic signaling connection with the network. Each radio frequency channel comprises a plurality of radio frequency devices, and if a certain radio frequency device fails and cannot work normally, the mobile terminal cannot access to a network of a corresponding frequency band or networks of all frequency bands, so that the mobile terminal cannot realize a normal communication function. Therefore, the following embodiments of the present invention provide a communication exception handling method, apparatus and mobile terminal.

For facilitating understanding of the embodiments of the present invention, first, a detailed description is given below of a communication exception handling method disclosed in the embodiments of the present invention with reference to the accompanying drawings.

Example one

Fig. 2 shows a flowchart of a communication exception handling method provided in this embodiment. The communication exception handling method provided by the embodiment is a handling process at the mobile terminal side. The mobile terminal comprises a plurality of main radio frequency paths and a plurality of standby radio frequency paths. For example, the mobile terminal is respectively provided with a main radio frequency path corresponding to the working frequency bands of different communication protocols, that is, there are a plurality of main radio frequency paths, and the working frequency band of each main radio frequency path is different. According to the protocol stack statistics, a plurality of standby radio frequency paths can be set. The number of the spare radio frequency paths may be equal to the number of the main radio frequency paths, or may be more or less than the number of the main radio frequency paths.

Referring to fig. 2, the communication exception handling method provided in this embodiment includes the following steps:

step S201, when a main radio frequency access with abnormal communication is monitored, one standby radio frequency access is selected from a plurality of standby radio frequency accesses to access the network.

When the mobile terminal monitors one of the following three situations, it can be determined that the situation of the abnormal communication of the main radio frequency channel exists: the main radio frequency access fails to access the network, the main radio frequency access is disconnected with the network or the main radio frequency access fails to self-check.

When the mobile terminal is started or starts some function, it will send out modulation signal through the main radio frequency channel, try to access the network, and establish basic signaling connection with the network. If the mobile terminal monitors that the times of the main radio frequency access trying to access the network exceed the set access times, or the time of the main radio frequency access trying to access the network exceeds the set access time, the main radio frequency access is considered to fail to access the network.

In the communication process of the mobile terminal and the network, if the disconnection time of the main radio frequency access and the network exceeds the set disconnection time; or, if the number of times of disconnection between the main rf path and the network in the unit time exceeds the set disconnection number, the main rf path may be considered to be disconnected from the network.

When the mobile terminal is started and initialized, the radio frequency device of the main radio frequency channel is subjected to self-checking. If a fault or damage of a certain radio frequency device is detected, namely the self-checking of the main radio frequency path fails, the mobile terminal cannot be connected with the network through the main radio frequency path, and at the moment, one standby radio frequency path can be selected from the multiple standby radio frequency paths to access the network.

When the mobile terminal monitors one of the three situations, one of the following ways can be selected to select one standby radio frequency access from the multiple standby radio frequency accesses to access the network:

the first mode is as follows: randomly selecting one standby radio frequency access from a plurality of standby radio frequency accesses to access a network; that is, any one of the spare rf paths can be selected to access the network.

The second way is: selecting a standby radio frequency access from a plurality of standby radio frequency accesses to access a network according to a preset sequence; the starting sequence of a plurality of standby radio frequency channels is preset, when a main radio frequency channel with abnormal communication is monitored, the standby radio frequency channel with the prior starting sequence is selected to access the network, and if the standby radio frequency channel with the prior starting sequence has faults or is occupied, the next standby radio frequency channel can be selected to access the network according to the starting sequence.

The third mode is as follows: selecting an inactive spare radio frequency access from a plurality of spare radio frequency accesses to access a network; specifically, one access may be randomly selected from the inactive standby radio frequency accesses to access the network, or may be selected from the inactive standby radio frequency accesses according to a preset sequence.

It will be appreciated that one of the alternate radio frequency paths may be selected multiple times to attempt to access the network. For example, when the standby radio frequency path selected from the plurality of standby radio frequency paths cannot be successfully accessed to the network for the first time, one standby radio frequency path selected from the remaining standby radio frequency paths can be used for the second attempt.

And step S202, when the standby radio frequency access is successfully accessed to the network, replacing the abnormal main radio frequency access with the standby radio frequency access for network communication.

If the access to the network through the standby radio frequency access is successful, the communication abnormity is caused by the fault of the main radio frequency access, and at the moment, the standby radio frequency access is used for replacing the main radio frequency access to carry out network communication. For example, a standby radio frequency path which is successfully accessed to the network can be adopted to replace a main radio frequency path which is abnormally communicated, so that the program is saved; and an alternative radio frequency path can be additionally selected to replace the main radio frequency path with abnormal communication.

If the network cannot be successfully accessed through the standby radio frequency access, the main radio frequency access is possibly not in failure, the communication abnormity is possibly caused by network failure, at the moment, the main/standby switching is not needed, the network is continuously tried to be accessed through the main radio frequency access, or related failure is prompted to a user, so that the user knows that the network cannot be connected but the access failure of the mobile terminal is caused by the current network failure.

For example, when the main rf path fails during data transmission between the mobile terminal and the network, the breakpoint of the data transmission process is recorded. If the standby radio frequency access is successfully started to access the network, the breakpoint position is sent to the network end through the standby radio frequency access or other standby radio frequency accesses, and data is continuously received or sent from the breakpoint position through the standby radio frequency access or other standby radio frequency accesses. And if the access to the network through the standby radio frequency access is not successful, prompting the user of the current network fault.

It is considered that the number of the main rf paths where the communication abnormality occurs may be larger than the spare rf paths or may be smaller than the spare rf paths. When the number of the main radio frequency paths with abnormal communication is less than or equal to the number of the standby radio frequency paths, one standby radio frequency path can be respectively allocated to the main radio frequency paths with abnormal communication in a one-to-one mode, and the allocated standby radio frequency paths are respectively used for replacing the corresponding main radio frequency paths to carry out network communication. When the number of the main rf paths with abnormal communication is greater than the number of the standby rf paths, a contention mechanism or a time-sharing mechanism is adopted to control the plurality of standby rf paths to replace the main rf paths with abnormal communication respectively for network communication.

In summary, in the communication anomaly handling method provided in this embodiment, when a main radio frequency path with communication anomaly is monitored, one spare radio frequency path is selected from multiple spare radio frequency paths to access the network; and if the standby radio frequency access can be successfully accessed to the network, replacing the main radio frequency access with abnormal communication with the standby radio frequency access to carry out network communication. By the method, if a device of a certain main radio frequency channel fails and the main radio frequency channel cannot be accessed to the network, the mobile terminal can adopt the standby radio frequency channel to connect the network without influencing the normal work of the mobile terminal, so that the problem that the mobile terminal cannot be continuously and normally used due to the device failure of the radio frequency channel is solved, the service life of the mobile terminal is prolonged to a certain extent, and the experience of a user in using the mobile terminal is improved.

Considering that there may be network environment abnormality that causes a network access failure or communication abnormality of the mobile terminal, if the standby radio frequency path is directly enabled in such a scenario, it is not helpful, based on this, the embodiment further optimizes the execution process of the step S201, and the step may specifically include: when a communication abnormity error code of the main radio frequency channel is monitored, judging whether the communication abnormity is caused by the device fault of the main radio frequency channel according to the error code; if yes, starting a standby radio frequency access network; if not, the standby radio frequency access network is not started, and the user can be prompted for fault information or other processing modes are adopted.

Specifically, an error code information table is stored in the memory of the mobile terminal, and the correspondence between the codes and the communication abnormality reasons is recorded in the error code information table. When judging whether the communication abnormity is caused by the device fault of the main radio frequency channel, acquiring a pre-stored error code information table; searching a communication abnormal reason corresponding to the error code from the error code information table; when the found communication abnormality is caused by a device fault and the faulty device is a device on a certain main radio frequency channel, it can be determined that the communication abnormality is caused by the device fault of the main radio frequency channel.

In the optimization processing manner in step S201, when the found communication abnormality is caused by a failure of another device except the main rf path or a network environment, it may be determined that the communication abnormality is not caused by the main rf path. Therefore, the standby radio frequency access is not required to be started to access the network, so that the invalid starting of the standby radio frequency access is avoided, the program is saved, and the energy consumption is saved.

Example two

The mobile terminal of this embodiment has main rf paths corresponding to different operating frequency bands, that is, there are multiple main rf paths. In order to save space and cost, the number of the standby radio frequency paths is smaller than that of the main radio frequency paths. The embodiment provides a communication exception handling method for the mobile terminal with the hardware.

Fig. 3 shows a flowchart of a communication exception handling method provided in this embodiment. As shown in fig. 3, the method comprises the steps of:

step S301, when a main radio frequency access with abnormal communication is monitored, one standby radio frequency access is selected from a plurality of standby radio frequency accesses to access the network.

Step S302, on the premise that the standby radio frequency access is successfully accessed to the network, the number of the main radio frequency access with abnormal communication is judged to be larger than that of the standby radio frequency access. If yes, step S305 is performed, and if no, step S303 is performed.

Step S303, allocating a standby rf path to the main rf path with abnormal communication in a one-to-one manner.

And step S304, the distributed standby radio frequency channels are used for replacing the corresponding main radio frequency channels respectively to carry out network communication.

That is, when the number of the main rf paths with abnormal communication is less than or equal to the number of the standby rf paths, one standby rf path may be allocated to each of the main rf paths with abnormal communication in a one-to-one manner, so as to replace the corresponding main rf path for network communication.

For example, if two standby radio frequency paths are provided in the mobile terminal, when one main radio frequency path, namely the first main radio frequency path, fails, one of the two standby radio frequency paths can be selected arbitrarily and allocated to the first main radio frequency path, and the allocated standby radio frequency path is used to replace the first main radio frequency path for network communication. When two main radio frequency paths, namely the first main radio frequency path and the second main radio frequency path, have faults, the two standby radio frequency paths can be respectively distributed to the first main radio frequency path and the second main radio frequency path, so that the two standby radio frequency paths respectively replace the corresponding main radio frequency paths to carry out network communication.

Step S305, allocating a spare rf path for each main rf path with abnormal communication.

Step S306, judging whether the same standby radio frequency channel is distributed to replace a plurality of main radio frequency channels with abnormal communication one by one. If yes, go to step S307, if no, go to step S304.

Step S307, a competition mechanism is adopted to control the standby radio frequency channels to respectively replace a plurality of main radio frequency channels with abnormal communication to carry out network communication.

Specifically, step S307 is implemented in the following manner:

dividing the time length of the standby radio frequency access to be distributed to the main radio frequency accesses according to the priority of the data service to be transmitted of the main radio frequency accesses, and controlling the standby radio frequency access to replace the main radio frequency accesses respectively to carry out network communication according to the divided time length.

For example, if the first backup radio frequency channel is allocated to replace the first main radio frequency channel and the second main radio frequency channel, the data service to be transmitted of the first main radio frequency channel is the micro-message voice, and the data service to be transmitted of the second main radio frequency channel is the mail. The priority of the WeChat voice is set to be higher than that of the mail, and at this time, 80% of the communication time length of the first standby video path can be allocated to the first main radio frequency path, and 20% of the communication time length of the first standby video path can be allocated to the second main radio frequency path. Therefore, the first standby radio frequency channel can replace the first main radio frequency channel and the second main radio frequency channel to carry out network communication according to the divided time length.

Of course, different priorities may also be set for each main rf path, the time length allocated to each main rf path by the spare rf path is divided according to the priority of each main rf path, and the spare rf path is controlled to replace multiple main rf paths for network communication according to the divided time length.

In the method for processing communication exception provided in this embodiment, when the number of the main radio frequency paths with communication exception is greater than the number of the standby radio frequency paths, a contention mechanism is adopted to control the plurality of standby radio frequency paths to replace the main radio frequency paths with communication exception to perform network communication. Therefore, the mobile terminal adopts fewer standby radio frequency paths to replace more main radio frequency paths for network communication, and when the main radio frequency paths are abnormal/failed, the normal network communication of the mobile terminal can be guaranteed, hardware resources are saved, space is saved, and cost is reduced. Meanwhile, the problems of mutual interference and chaos in the communication process when a plurality of standby radio frequency channels are adopted to replace a plurality of main radio frequency channels for network communication are avoided.

EXAMPLE III

For a mobile terminal with the number of the standby radio frequency paths smaller than the number of the main radio frequency paths, this embodiment provides another communication exception handling method, and when the number of the main radio frequency paths with the communication exception is greater than the number of the standby radio frequency paths, a time-sharing mechanism is adopted to control the plurality of standby radio frequency paths to respectively replace the main radio frequency paths with the communication exception to perform network communication.

Fig. 4 shows a flowchart of a communication exception handling method provided in this embodiment. As shown in fig. 4, the method includes the steps of:

step S401, when a main radio frequency access with abnormal communication is monitored, one standby radio frequency access is selected from a plurality of standby radio frequency accesses to access the network.

Step S402, on the premise that the standby radio frequency access is successfully accessed to the network, judging that the number of the main radio frequency access with abnormal communication is larger than that of the standby radio frequency access. If yes, step S405 is performed, and if no, step S403 is performed.

Step S403, respectively allocating a standby rf path to the main rf path with abnormal communication in a one-to-one manner.

And S404, using the allocated standby radio frequency channels to respectively replace the corresponding main radio frequency channels for network communication.

Step S405, allocating a spare rf path to each main rf path with abnormal communication.

Step S406, determining one by one whether the same standby RF path is allocated to replace a plurality of main RF paths with abnormal communication. If yes, step S407 is executed, and if no, step S404 is executed.

Step S407, using a time-sharing mechanism to control the standby rf paths to replace the abnormal multiple main rf paths for network communication.

Specifically, step S407 may be implemented as follows:

uniformly dividing the use time period of the standby radio frequency access into a plurality of time slots to be allocated; and controlling the standby radio frequency channel to sequentially replace a plurality of main radio frequency channels to carry out network communication according to the divided time slots to be allocated.

For example, if a first spare rf path is allocated to replace a first main rf path and a second main rf path, the time period of use of the first spare rf path may be evenly divided into a plurality of time slots to be allocated; and allocating the nth time slot to be allocated to the first main radio frequency channel, allocating the (n + 1) th time slot to be allocated to the second main radio frequency channel, allocating the (n + 2) th time slot to be allocated to the first main radio frequency channel, and so on, so that the first standby radio frequency channel sequentially replaces a plurality of main radio frequency channels according to the divided time slots to be allocated to carry out network communication.

The embodiment adopts a time-sharing mechanism to control a plurality of standby radio frequency paths to respectively replace a main radio frequency path with abnormal communication to carry out network communication. Therefore, the mobile terminal can adopt fewer standby radio frequency channels to replace more main radio frequency channels for network communication, hardware resources are saved, space is saved, and cost is reduced. Meanwhile, the normal work of the mobile terminal is not influenced when the main radio frequency channel breaks down, so that the user experience is improved.

It should be noted that the above embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are not described repeatedly and can be referred to each other.

Example four

Corresponding to the communication exception handling method provided by the above embodiment, the embodiment provides a communication exception handling device applied to a mobile terminal, where the mobile terminal includes a plurality of main radio frequency paths and a plurality of standby radio frequency paths. As shown in fig. 5, the apparatus includes the following modules.

A communication anomaly determination module 501, configured to determine that a communication anomaly of the main rf path occurs when the main rf path is monitored to include one of the following situations: the main radio frequency access fails to access the network, the main radio frequency access is disconnected with the network or the main radio frequency access fails to self-check.

The failure of accessing the primary radio frequency access to the network includes, but is not limited to, the following two situations: the number of times of trying to access the network by the main radio frequency access exceeds the set access number; and secondly, the time length of the main radio frequency access trying to access the network exceeds the set access time length.

The disconnection of the main rf path from the network includes, but is not limited to, the following two situations: the disconnection time of the main radio frequency access and the network exceeds the set disconnection time; and secondly, in unit time, the disconnection times of the main radio frequency channel and the network exceed the set disconnection times.

The failure of the self-checking of the main radio frequency path means that when the mobile terminal is started and initialized, the radio frequency device of the main radio frequency path is self-checked, and a certain radio frequency device is detected to be in fault or damaged.

A standby radio frequency path starting module 502, configured to select one standby radio frequency path from multiple standby radio frequency paths to access a network when a main radio frequency path with abnormal communication is monitored;

and a radio frequency path switching module 503, configured to replace the abnormal main radio frequency path with the standby radio frequency path to perform network communication after the standby radio frequency path is successfully accessed to the network.

In the communication anomaly processing device provided by this embodiment, when a main radio frequency path with communication anomaly is monitored, one standby radio frequency path is selected from multiple standby radio frequency paths to access a network. And if the standby radio frequency access can be successfully accessed to the network, replacing the main radio frequency access with the standby radio frequency access to carry out network communication. Through the technical means, if a device of a certain main radio frequency channel breaks down, and the main radio frequency channel cannot be connected to the network, the mobile terminal can use the standby radio frequency channel to connect the network, so that the normal work of the mobile terminal is not influenced, and the user experience is improved.

In a preferred embodiment, the number of the standby radio frequency paths in the mobile terminal may be less than the number of the main radio frequency paths in order to save space and cost. For the mobile terminal, the radio frequency path switching module 503 may be further configured to: when the number of the main radio frequency paths with abnormal communication is less than or equal to the number of the standby radio frequency paths, respectively allocating one standby radio frequency path for the main radio frequency paths with abnormal communication according to a one-to-one mode, and respectively replacing the corresponding main radio frequency paths with the allocated standby radio frequency paths to carry out network communication.

When the number of the main radio frequency paths with abnormal communication is larger than that of the standby radio frequency paths, respectively allocating one standby radio frequency path to each main radio frequency path with abnormal communication; when one spare radio frequency channel is distributed to replace a plurality of main radio frequency channels with abnormal communication, a competition mechanism or a time-sharing mechanism is adopted to control the spare radio frequency channel to respectively replace the plurality of main radio frequency channels to carry out network communication.

Specifically, one implementation manner is to adopt a contention mechanism, divide the time length allocated to the multiple main radio frequency paths by the standby radio frequency paths according to the priorities of the data services to be transmitted by the multiple main radio frequency paths, and control the standby radio frequency paths to replace the multiple main radio frequency paths respectively for network communication according to the divided time lengths. The other realization mode is that a time-sharing mechanism is adopted to evenly divide the use time period of the standby radio frequency channel into a plurality of time slots to be allocated; and controlling the standby radio frequency channels to sequentially replace a plurality of main radio frequency channels to carry out network communication according to the divided time slots to be allocated.

Therefore, fewer standby radio frequency channels can be adopted to replace more main radio frequency channels for network communication, hardware resources are saved, and normal work of the mobile terminal is not influenced when the main radio frequency channels break down, so that the user experience is improved.

The communication exception handling apparatus provided in the foregoing embodiment has the same implementation principle and technical effect as those of the foregoing method embodiment, and for the sake of brief description, reference may be made to corresponding contents in the foregoing method embodiment for parts of the apparatus embodiment that are not mentioned.

In the mobile terminal illustrated in fig. 6, four main rf paths, namely a first main rf path 31, a second main rf path 32, a third main rf path 33, and a fourth main rf path 34, are provided corresponding to different operating frequency bands. Meanwhile, two spare rf paths are provided, namely a first spare rf path 35 and a second spare rf path 36. Each main radio frequency channel comprises a channel switch, a receiving filter, a power amplifier and other radio frequency devices so as to realize the connection and communication with the network. Each spare radio frequency path also comprises a path switch, a receiving filter, a power amplifier and other devices, so that when the main radio frequency path fails, the spare radio frequency path can replace any main radio frequency path to access the network. It should be noted that, in the mobile terminal provided in the embodiment of the present invention, the number of the main rf paths is not limited to four, and may be more than four, or less than four. Likewise, the number of spare rf paths is not limited to two, and may be more than two or less than two.

Taking the mobile terminal shown in fig. 6 as an example, the mobile terminal is provided with four main rf paths and two standby rf paths. By applying the method provided by the embodiment, when one of the main rf paths is abnormal in communication, one standby rf path may be selected from the two standby rf paths randomly or according to a preset sequence to replace the main rf path for network communication. When two of the main radio frequency paths have communication abnormality, a standby radio frequency path can be respectively allocated to the main radio frequency paths with communication abnormality according to a one-to-one mode.

When three of the four main rf paths are abnormal in communication, if the first main rf path, the second main rf path, and the third main rf path are all abnormal in communication, a spare rf path needs to be allocated to each main rf path with abnormal communication. It is assumed that a first spare rf path is allocated to the first main rf path and the second main rf path, and a second spare rf path is allocated to the third main rf path. The first standby radio frequency channel can be controlled to replace the first main radio frequency channel and the second main radio frequency channel respectively for network communication through the competition mechanism or the time-sharing mechanism, and the second standby radio frequency channel can be controlled to replace the third main radio frequency channel for network communication.

When the main rf path and the standby rf path communicate with the network, any communication standard or protocol may be used, including but not limited to Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Message Service (SMS), etc.
