Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more clear, the present disclosure will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the scope of protection of the present disclosure.
Before the mobile terminal performs voice communication through the VOLTE communication network, a Long Term Evolution (LTE) network needs to be attached and an IMS network needs to be registered.
The process of attaching the mobile terminal to the LTE network may include: the mobile terminal transmits a radio resource Connection Request (RRC Connection Request) to an access network device of the LTE network. After receiving the radio resource Connection request, the access network device of the LTE network may send a radio resource Connection Setup (RRC Connection Setup) message to the mobile terminal. After receiving the radio resource connection confirmation message, the mobile terminal sends an Attach Request (Attach Request) message to the access network equipment of the LTE network, so that the access network equipment of the LTE network can complete the attachment of the mobile terminal according to the Attach Request message.
It should be noted that the LTE network may also receive a tracking area update request (tracking area update request) message of the mobile terminal, and may acquire a new Location Area Code (LAC) of the mobile terminal according to the tracking area update request message.
The step of registering the IMS network by the mobile terminal may specifically include: the mobile terminal sends a first registration Request (Register Request) message to the IMS network, where the first registration Request message carries an authentication identifier of the mobile terminal, and the IMS network may calculate an authentication vector according to the authentication identifier carried in the first registration Request message after receiving the first registration Request message, and send a response message to the mobile terminal according to the authentication vector, where the response message carries the authentication vector. The mobile terminal authenticates the identity of the IMS network according to the authentication vector carried in the received response message, and when the authentication is passed, the mobile terminal sends a second registration Request (Register Request) message to the IMS network, wherein the second registration Request message carries the authentication vector. After receiving the second registration request message, the IMS network may authenticate the identity of the mobile terminal again according to the authentication vector carried in the second registration request, and if the authentication is successful, send an authentication success message to the mobile terminal, and allow the mobile terminal to access the IMS network, so that the mobile terminal may complete the step of registering and authenticating the IMS network.
The embodiment of the disclosure is stated on the basis that the mobile terminal has successfully attached to the LTE network and successfully registered to the IMS network.
Fig. 1 is a flow chart illustrating a communication method that may be applied in a mobile terminal according to an example embodiment, and as shown in fig. 1, the method may include:
in step 101, the success rate of VOLTE communication of the current serving cell is detected.
The mobile terminal can record and update the VOLTE communication success rate of the current service cell of the mobile terminal in real time according to the VOLTE communication condition of the current service cell, so that the VOLTE communication success rate of the current service cell can be detected in real time according to the recorded VOLTE communication success rate.
In step 102, when the success rate of VOLTE communication of the current serving cell is lower than a preset threshold, the voice communication network is switched from the VOLTE communication network to the target communication network.
The preset threshold may be a default configuration of the mobile terminal, or may be preset based on a use habit for the user. The target communication network may be a Circuit Switched (CS) network. For example, assuming that the preset threshold is 95%, if the success rate of VOLTE communication of the current serving cell is lower than 95%, the mobile terminal may switch the voice communication network from the VOLTE communication network to the CS network.
In step 103, when voice communication is performed again, voice communication is performed through the target communication network.
For example, when the mobile terminal initiates voice communication again in the current serving cell after switching the voice communication network from the VOLTE communication network to the CS network, the voice communication may be performed through the CS network.
To sum up, according to the communication method provided by the embodiment of the present disclosure, when the 4G network signal of the mobile terminal is poor, the mobile terminal may be actively switched to other voice communication modes, so that when the mobile terminal performs voice communication again, voice communication may not be performed through the VOLTE communication network, but performed using the switched network, thereby avoiding a situation that voice communication is still attempted through the VOLTE network after voice communication through the VOLTE network fails, and thus, the communication success rate of the mobile terminal may be improved.
Fig. 2 is a flow chart illustrating another communication method that may be applied in a mobile terminal according to an example embodiment, and as shown in fig. 2, the method may include:
in step 201, the mobile terminal detects the success rate of VOLTE communication of the current serving cell.
In practical applications, when the success rate of VOLTE communication of the mobile terminal is low, it indicates that the current 4G network signal of the mobile terminal is poor, and the probability of successful communication of the mobile terminal in the poor 4G network signal is still small even if the mobile terminal continuously tries to perform voice communication through the VOLTE network.
Specifically, the mobile terminal can record and update the VOLTE communication success rate of the current serving cell of the mobile terminal in real time according to the VOLTE communication condition of the current serving cell, so that the VOLTE communication success rate of the current serving cell can be detected in real time according to the recorded VOLTE communication success rate.
In step 202, the mobile terminal de-registers with the VOLTE communication network.
When the mobile terminal deregisters the VOLTE communication network, the mobile terminal may send a deregistration message to the IMS network, where the deregistration message may be used to indicate to the IMS network that the mobile terminal is to deregister the VOLTE communication network, and for example, the deregistration message may carry the following code:
Figure BDA0001637622070000071
in step 203, the mobile terminal notifies the application layer of the mobile terminal of the registration status of the VOLTE communication network.
Specifically, after the mobile terminal deregisters the VOLTE communication network, the registration state of the VOLTE becomes unregistered, and the mobile terminal can send the registration state to the application layer of the mobile terminal, so that the application layer can avoid performing communication again through the VOLTE communication network but through other communication networks based on the registration state.
In step 204, when the success rate of VOLTE communication of the current serving cell is lower than a preset threshold, the mobile terminal stores the LAC corresponding to the current serving cell.
In general, a Mobile terminal may implement a Mobile communication service through a Public Land Mobile Network (PLMN), where the PLMN may refer to a Network coverage area of a certain operator, and the coverage area may be divided into a plurality of location areas, and each location area may include at least one serving cell. Wherein different location areas may be uniquely identified with different LACs. When the mobile terminal detects that the success rate of VOLTE communication of the current serving cell is lower than the preset threshold, the LAC corresponding to the current serving cell may be stored, so as to know which serving cell has a poor 4G network signal.
When voice communication is performed again, the mobile terminal performs voice communication through the CS network in step 205.
The voice communication through the CS network means that when the voice communication is performed, the voice communication signal is sent through the CS domain, so that the network element in the CS network provides the voice communication service for the mobile terminal, and the situation of communication failure caused by bad 4G network signals can be avoided.
In step 206, when it is detected that the mobile terminal is handed over to a new serving cell, the mobile terminal acquires the LAC corresponding to the new serving cell.
In practical application, when the mobile terminal detects that it is switched to a new location area, the mobile terminal may send a tracking location area update request message to the LTE network, where the tracking location area update request message may be used to instruct the LTE network to synchronously update the LAC corresponding to the serving cell where the mobile terminal is located, for example, the tracking location area update request message may carry the following code:
07:41:19.552[0xB0ED]LTE NAS EMM Plain OTA Outgoing Message
pkt_version＝1(0x1)
rel_number＝9(0x9)
rel_version_major＝5(0x5)
rel_version_minor＝0(0x0)
security_header_or_skip_ind＝0(0x0)
prot_disc＝7(0x7)(EPS mobility management messages)
msg_type＝72(0x48)(Tracking area update request)
lte_emm_msg
emm_ta_update_req
tsc_asme＝0(0x0)(cached sec context)
nas_key_set_id_asme＝1(0x1)
in the embodiment of the present disclosure, after the mobile terminal sends the tracking location area update request message to the LTE network, the LAC corresponding to the new serving cell may be acquired, and since the mobile terminal may store the LAC corresponding to the serving cell whose VOLTE communication success rate is lower than the preset threshold, after the mobile terminal acquires the LAC corresponding to the new serving cell, whether the VOLTE communication success rate of the new serving cell is lower than the preset threshold may be determined according to whether the mobile terminal stores the LAC corresponding to the new serving cell, and then different measures may be taken according to different determination results.
In step 207, when the mobile terminal does not store the LAC corresponding to the new serving cell, the VOLTE communication network is re-registered.
When the mobile terminal does not store the LAC corresponding to the new serving cell, it indicates that the VOLTE communication network in the new serving cell is uncertain, and therefore, the mobile terminal may re-register the VOLTE communication network.
Specifically, the mobile terminal may send a registration request message to the IMS network, where the registration request message may be used to indicate that the IMS network is to register the mobile terminal with the VOLTE communication network, and for example, the registration request message may carry the following codes:
Figure BDA0001637622070000081
Figure BDA0001637622070000091
in step 208, when voice communication is performed again, the mobile terminal performs voice communication through the VOLTE communication network.
When the mobile terminal performs voice communication in the new serving cell, voice communication may be performed through the VOLTE communication network.
It should be noted that, in the above step 206, if the LAC corresponding to the new serving cell is stored in the mobile terminal, it indicates that the VOLTE communication success rate of the new serving cell is lower than the preset threshold, and the communication success rate when using the VOLTE network for communication is low, so that it is not necessary to re-register the VOLTE communication network, and when performing the voice call again, the voice call is performed through the target communication network, that is, the voice call is performed through the CS network. In order to realize the dynamic switching between the CS network and the VOLTE communication network, when the mobile terminal is restarted, the LAC stored in the mobile terminal may be cleared and the VOLTE communication network may be newly registered, so that when the mobile terminal performs voice communication again, voice communication may be performed through the VOLTE communication network. The way of re-registering the VOLTE communication network by the mobile terminal is the same as the way of re-registering the VOLTE communication network by the mobile terminal in step 207, which is not described herein again in this embodiment of the disclosure.
It should be further noted that, the order of the steps of the communication method of the mobile terminal provided in the embodiment of the present disclosure may be appropriately adjusted, for example, the order of the steps 202 and 203 may be appropriately adjusted; the steps can be increased or decreased according to the situation. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure is covered by the protection scope of the present disclosure, and thus, the detailed description thereof is omitted.
To sum up, according to the communication method provided by the embodiment of the present disclosure, when the 4G network signal of the mobile terminal is poor, the mobile terminal may be actively switched to other voice communication modes, so that when the mobile terminal performs voice communication again, voice communication may not be performed through the VOLTE communication network, but performed using the switched network, thereby avoiding a situation that voice communication is still attempted through the VOLTE network after voice communication through the VOLTE network fails, and thus, the communication success rate of the mobile terminal may be improved.
