Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
An embodiment of the present invention provides a calling method, as shown in fig. 1, the method may include:
s101, when the mobile terminal is in the emergency call mode, receiving a first call instruction, and judging whether at least two call modes are supported or not according to the first call instruction.
The calling method provided by the embodiment of the invention is suitable for a scene that the terminal carries out emergency calling.
In the embodiment of the invention, when the terminal does not have the SIM card or is in a service limited mode such as a flight mode, the terminal can not carry out normal communication, and at the moment, the terminal can only initiate an emergency call.
In this embodiment of the present invention, the at least two call modes may include an IMS emergency call mode corresponding to an LTE network and a CS domain call mode corresponding to a Wideband Code Division Multiple Access (WCDMA), a CDMA, a Global System for Mobile Communication (GSM), and the like, and are specifically selected according to an actual situation, and the embodiment of the present invention is not specifically limited.
In the embodiment of the invention, the condition that the terminal initiates the emergency call is that the terminal supports at least two calling modes, when the terminal initiates the emergency call, whether the terminal supports at least two calling modes is judged firstly, and only when the terminal supports at least two calling modes and the calling of the terminal adopting the first calling mode fails, the terminal can be switched to the second calling mode to continue calling.
In the embodiment of the invention, when the terminal is in the emergency call mode, the terminal receives a first call instruction sent by a user, and the terminal starts to judge whether to support at least two call modes according to the received first call instruction.
Illustratively, under the condition that an LTE network and a WCDMA network coexist, a terminal registers on the WCDMA network, after the terminal successfully registers the WCDMA network, network side equipment sends a registration success instruction to the terminal, and after the terminal receives the registration success instruction, the terminal judges that CS domain calling is supported; as shown in fig. 2, a terminal initiates a registration request to an LTE network through an Attach request message, when the terminal completes registration on the LTE network, a network side device recovers the terminal through an Attach accept Meg Attach response message, and carries an EMC _ BS (EMC _ BS) field in S1Mode for supporting Emergency bearer service in S1Mode supported in the Attach accept Meg Attach response message, where the field may indicate whether an IMS Emergency call is supported, when the field is 1, the field indicates that the IMS Emergency call is supported, and when the field is 0, the field indicates that the IMS Emergency call is not supported.
S102, when the fact that at least two calling modes are supported is judged, a priority network is determined according to a preset calling strategy, the priority network corresponds to a first calling mode in the at least two calling modes, and the preset calling strategy is used for judging the priority network corresponding to the first calling mode in the at least two calling modes.
When the terminal determines that at least two call modes are supported, the terminal determines a priority network for preferentially making an emergency call.
In the embodiment of the invention, the terminal is preset with a preset calling strategy, and when the terminal judges that at least two calling modes are supported, the terminal determines a first calling mode corresponding to a priority network for preferentially calling from the at least two calling modes according to the preset calling strategy.
Optionally, the terminal in the embodiment of the present invention may determine a priority network from the at least two current networks according to a preset priority principle, specifically, the terminal ranks the at least two current networks according to a preset index, and determines a current network with a best preset index from the at least two current networks as the priority network according to a ranking result, or determines a priority network from the at least two current networks according to a priority setting preset by a user according to a determination result, specifically, the setting is performed according to an actual situation, and the embodiment of the present invention is not specifically limited.
For example, as shown in fig. 3, two options are set for emergency calls on a setting interface of a mobile phone, one is an "adaptive optimal mode" and the other is a "manual setting mode", when a user selects the "adaptive optimal mode", the mobile phone selects an optimal network as a priority network according to the acquired network capability, and when the user selects the "manual setting mode", the user selects the priority network from at least two current networks on the setting interface.
It can be understood that the terminal displays the judgment result of whether the terminal supports at least two calling modes, the user can select the preferred network according to the judgment result, and can set the calling mode according to the network environment when the user is familiar with the network system, thereby saving the time for initiating the emergency call.
In the embodiment of the invention, when the terminal judges that the terminal supports at least two calling modes, the terminal displays according to the judgment result, the judgment result comprises at least two current networks corresponding to the at least two calling modes, and at the moment, the terminal determines the prior network.
For example, as shown in fig. 4, a Modem bottom layer of the terminal obtains whether the IMS emergency call is supported by analyzing an Attach accept Meg Attach response message, the terminal sets an Interface in advance, the Modem bottom layer reports whether the IMS emergency call is supported to a User Interface (UI) through the Interface, and after the UI Interface receives the message reported by the Modem bottom layer, an icon is added to a status bar to prompt a User whether the IMS emergency call is supported.
In the embodiment of the invention, the terminal can determine a priority network from at least two current networks according to a preset call strategy, and when the terminal fails to use the priority network to carry out a first call, the terminal determines a standby network from the at least two current networks to carry out a second call; the terminal may also determine a priority network and a standby network from at least two current networks according to a preset call policy, and when the terminal fails to use the priority network to perform the first call, the terminal directly uses the standby network to perform the second call, which is specifically set according to an actual situation.
Further, when the terminal determines that the at least two call modes are not supported, the terminal initiates a third emergency call by using a third call mode of the at least two call modes, and displays the third call mode corresponding to the third emergency call.
For example, as shown in fig. 5, when the mobile phone is in a service-limited mode such as an airplane mode, the mobile phone determines whether the mobile phone is supported to initiate an IMS emergency call in the service-limited mode by receiving an IMS-emergency support-r9 field in a System Information Block (SIB1, System Information Block Type1) of the network-side device; the mobile phone stores an IMS-emergency support-r9 field, and when the mobile phone initiates an emergency call, if the IMS-emergency support-r9 field is 1, the mobile phone prompts on an interface that the IMS emergency call is being called; if the field of the ims-EmergenestSupport-r 9 is 0, the emergency call of the CS domain is directly initiated, and meanwhile, the interface prompts that the emergency call of the CS domain is calling out.
It can be understood that, when the terminal determines that the at least two modes are not supported, the terminal initiates a third emergency call by using a third call mode of the at least two call modes, and displays the third call mode corresponding to the third emergency call, so that the user can know the currently available network and improve the success rate of the priority network set by the user.
S103, responding to the first calling instruction, and carrying out first calling in a first calling mode.
And after the terminal determines the priority network, the terminal responds to the first call instruction and carries out the first call by adopting a first call mode corresponding to the priority network.
In the embodiment of the invention, when the terminal determines that the LTE network is the priority network, the terminal adopts an IMS emergency call mode to carry out a first call; when the terminal determines that the WCDMA, CDMA and other networks are the priority networks, the terminal performs a first call in a CS domain emergency call mode.
And S104, when the first call fails, switching the first call mode to a second call mode to carry out a second call, wherein the second call mode is a call mode except the first call mode in at least two call modes.
When the terminal adopts the first calling mode to carry out the first calling, two results of the first calling success and the first calling failure are generated, and when the terminal adopts the first calling mode to carry out the first calling failure, the terminal starts to determine a second calling mode corresponding to the standby network and switches the first calling mode to the second calling mode to carry out the second calling.
Specifically, in the embodiment of the present invention, when the terminal fails to perform the first call in the first call mode, the terminal sends a first call failure message to the network side device, after the network side device receives the first call failure message sent by the terminal, the network side device sends a switching instruction carrying information related to the second call mode corresponding to the standby network to the terminal according to the first call failure message, the terminal receives the switching instruction sent by the network side device, disconnects the priority network according to the switching instruction, switches to the standby network, and performs the second call in the second call mode corresponding to the standby network.
For example, as shown in fig. 6, a mobile phone first initiates an IMS emergency call on an LTE network, and when the mobile phone receives an IMS emergency call failure sent by a network-side device, the mobile phone sends an Extended Service Request (ESR) message to the network-side device, where the message type of the ESR message is a mobile authorization CS fallback establishment call, and at this time, the network-side device sends a Radio Resource Control (RRC) Connection Release message to tell the mobile phone to disconnect from the LTE network and carry an instruction that a terminal performs a CS domain call on the WCDMA network, and then the terminal completes the CS domain emergency call on the WCDMA network.
For example, as shown in fig. 7, when the mobile phone is currently registered in the LTE network, the user sets the priority network as a network corresponding to the CS domain call mode, at this time, the mobile phone first initiates a CS domain emergency call on the WCDMA network, and when the mobile phone receives that the CS domain emergency call sent by the network side device fails, the mobile phone initiates registration and initiates an IMS emergency call on the LTE emergency call server.
It can be understood that, under the condition that the terminal supports at least two call modes, when the terminal is in the emergency call mode, the terminal first performs a first call by using the first call mode corresponding to the priority network, when the first call fails, the terminal switches from the priority network to the standby network, and performs a second call by using the second call mode corresponding to the standby network, so that the situation that a user re-initiates sequential emergency calls after the terminal fails to perform the first call by using the first call mode corresponding to the priority network is avoided, and the success rate of the emergency calls can be improved.

An embodiment of the present invention provides a calling method, as shown in fig. 8, the method may include:
s201, a terminal sends a network registration request to a network side device to request to access at least two current networks, wherein the at least two current networks correspond to at least two calling modes.

In the embodiment of the invention, when the terminal is started, the terminal searches the current network and registers the current network, firstly, the terminal sends a network registration request to the network side equipment and requests the network side equipment to send a list of accessible networks.
S202, the terminal receives a first response instruction which is sent by the network side equipment and responds to the network registration request, and access of at least two current networks is achieved according to the first response instruction.
After the terminal sends a network registration request to the network side equipment, the network side equipment sends a first response instruction to the terminal, and the terminal successfully accesses at least two current networks according to the received first response instruction.
In the embodiment of the invention, the network side equipment sends the list of accessible networks to the terminal according to the network registration request sent by the terminal, the terminal selects at least two current networks from the list of accessible networks and sends the selection result to the network side equipment, and the network side equipment accesses the terminal into the at least two current networks according to the selection result to finish the access of the terminal into the at least two current networks.
In the embodiment of the invention, the first response instruction carries judgment information for judging whether to support at least two calling modes.
In the embodiment of the invention, at least two current networks correspond to at least two calling modes.
S203, when the terminal is in the emergency call mode, the terminal receives a first call instruction and judges whether to support at least two call modes according to the first call instruction.
Here, the description of S203 in the embodiment of the present invention is identical to the description of S101 in the first embodiment, and is not repeated here.
And S204, the terminal acquires and displays the judgment result, wherein the judgment result comprises at least two current networks corresponding to at least two calling modes.
And when the terminal judges whether the terminal supports at least two calling modes, the terminal acquires a judgment result and displays the judgment result. The judgment result obtained by the terminal may include at least two current networks corresponding to the at least two call modes.
In the embodiment of the invention, when the terminal acquires and judges whether the terminal supports at least two calling modes, the terminal displays the current network corresponding to each calling mode in the at least two calling modes supported by the terminal on the display interface of the terminal.
For example, as shown in fig. 4, a Modem bottom layer of the terminal obtains whether the IMS emergency call is supported by analyzing an Attach accept Meg Attach response message, the terminal sets an Interface in advance, the Modem bottom layer reports whether the IMS emergency call is supported to a User Interface (UI) through the Interface, and after the UI Interface receives the message reported by the Modem bottom layer, an icon is added to a status bar to prompt a User whether the IMS emergency call is supported.
S205, when the terminal judges that the terminal supports at least two calling modes, a priority network is determined according to a preset calling strategy, the priority network corresponds to a first calling mode in the at least two calling modes, and the preset calling strategy is used for judging the priority network corresponding to the first calling mode in the at least two calling modes.
Here, the description of S205 in the embodiment of the present invention is identical to the description of S102 in the first embodiment, and is not repeated here.
S206, the terminal responds to the first calling instruction and carries out the first calling in the first calling mode.
Here, the description of S206 in the embodiment of the present invention is identical to the description of S103 in the first embodiment, and is not repeated here.
S207, when the first call fails, the terminal sends a first call failure message to the network side equipment.
When the terminal fails to perform the first call in the first call mode, the terminal sends a first call failure message to the network side equipment so as to perform switching operation.
In the embodiment of the invention, when the terminal fails to use the first call to carry out the first call, the terminal sends a first call failure message to the network side equipment.
And S208, the terminal receives a switching instruction sent by the network side equipment, wherein the switching instruction is used for indicating to disconnect the priority network and switch to a standby network, and the standby network is a network corresponding to the second call mode.
After the terminal sends the first call failure message to the network side equipment, the network side equipment sends a switching instruction carrying the relevant information of the standby network to the terminal.
In the embodiment of the invention, when the network side equipment receives the first call failure sent by the terminal, the network side equipment sends a switching instruction carrying the information related to the standby network to be switched to the terminal.
S209, the terminal switches the first calling mode to a second calling mode corresponding to the standby network according to the switching instruction, and performs a second calling, wherein the second calling mode is a calling mode except the first calling mode in at least two calling modes.
After the terminal receives the switching instruction sent by the network side equipment, the terminal switches from the first calling mode corresponding to the prior network to the second calling mode corresponding to the standby network according to the switching instruction, and a second call is carried out.
In the embodiment of the invention, after receiving the information related to the standby network to be switched, the terminal switches from the prior network to the standby network and carries out the second call by adopting the second call mode corresponding to the standby network.
For example, as shown in fig. 6, a mobile phone first initiates an IMS emergency call on an LTE network, and when the mobile phone receives an IMS emergency call failure sent by a network-side device, the mobile phone sends an Extended Service Request (ESR) message to the network-side device, where the message type of the ESR message is a mobile authorization CS fallback establishment call, and at this time, the network-side device sends a Radio Resource Control (RRC) Connection Release message to tell the mobile phone to disconnect from the LTE network and carry an instruction terminal to perform a CS domain call on the WCDMA network, and then the terminal completes the CS domain emergency call on the WCDMA network.
For example, as shown in fig. 7, when the mobile phone is currently registered in the LTE network, the user sets the priority network as a network corresponding to the CS domain call mode, at this time, the mobile phone first initiates a CS domain emergency call on the WCDMA network, and when the mobile phone receives that the CS domain emergency call sent by the network side device fails, the mobile phone initiates registration and initiates an IMS emergency call on the LTE emergency call server.
And S210, when the terminal judges that the terminal does not support at least two calling modes, the terminal performs a third calling by adopting the acquired third calling mode and displays the third calling mode, wherein the third calling mode is any one of the at least two calling modes.
In the embodiment of the invention, after the terminal judges whether the terminal supports at least two calling modes, two judgment results are generated, namely the terminal supports at least two calling modes and the terminal does not support at least two calling modes, when the terminal judges that the terminal does not support at least two calling modes, the terminal adopts a third calling mode of the at least two calling modes to initiate a third emergency call, and displays the third calling mode corresponding to the third emergency call.
For example, as shown in fig. 5, when the mobile phone is in a service-limited mode such as an airplane mode, the mobile phone determines whether the mobile phone is supported to initiate an IMS emergency call in the service-limited mode by receiving an IMS-emergency support-r9 field in a System Information Block (SIB1, System Information Block Type1) of the network-side device; the mobile phone stores an IMS-emergency support-r9 field, and when the mobile phone initiates an emergency call, if the IMS-emergency support-r9 field is 1, the mobile phone prompts on an interface that the IMS emergency call is being called; if the field of the ims-EmergenestSupport-r 9 is 0, the emergency call of the CS domain is directly initiated, and meanwhile, the interface prompts that the emergency call of the CS domain is calling out.
It can be understood that, when the terminal determines that the at least two modes are not supported, the terminal initiates a third emergency call by using a third call mode of the at least two call modes, and displays the third call mode corresponding to the third emergency call, so that the user can know the currently available network and improve the success rate of the priority network set by the user.
It can be understood that, under the condition that the terminal supports at least two call modes, when the terminal is in the emergency call mode, the terminal first performs a first call by using the first call mode corresponding to the priority network, when the first call fails, the terminal switches from the priority network to the standby network, and performs a second call by using the second call mode corresponding to the standby network, so that the situation that a user re-initiates sequential emergency calls after the terminal fails to perform the first call by using the first call mode corresponding to the priority network is avoided, and the success rate of the emergency calls can be improved.
