All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a terminal calling method, which is shown in a combined figure 1 and comprises the following steps:
step 101: the terminal receives a calling call trigger input of a user.
The calling call trigger input may be a virtual call key displayed on a display screen of the terminal, or a single-click operation, a double-click operation, a sliding operation, a long-press operation, and the like of an entity call key set on the terminal.
Step 102: and responding to the calling call trigger input, and acquiring the current network state of the terminal.
Wherein the network state comprises: a registration state of the terminal on an IP Multimedia Subsystem (IMS) network and a signal coverage state of a Long Term Evolution (LTE) network.
And realizing the type selection of the calling conversation of the terminal according to the network parameters contained in the network state.
Step 103: and selecting the target type of the calling conversation according to the network state.
The types of the calling conversation comprise a circuit domain voice call and a packet domain voice call.
Specifically, the terminal may select a target type of a calling party call through an internal voice type decision device, and the voice type decision device, based on a current network environment, may flexibly select a type of a voice call through a current network state of the terminal, that is, implement a Circuit Switched (CS) domain voice call, that is, a CS domain voice call, or a Packet Switched (PS) domain voice call, that is, a PS domain voice call.
When the voice type decision means makes a selection of the voice call type of the calling call, it may be that the voice type decision means displays by selecting a target voice call means, wherein the selectable target voice call means includes: a Circuit Switched Fallback (CSFB) Voice call apparatus for performing a Circuit domain Voice call, and a Voice over Long-Term Evolution (VoLTE) Voice call apparatus for performing a packet domain Voice call.
Referring to fig. 2, the voice type decision device is connected to the CSFB voice call device and the VoLTE voice call device, respectively. The selection of the voice call type of the calling call comprises the selection of a CS (circuit) domain and a PS (packet) domain, namely the selection of a CSFB voice optimization device and a VoLTE voice optimization device, and the call completing rate is improved by selecting the most reasonable voice type.
When the selected target type of the calling conversation is a circuit domain voice call, selecting a CSFB voice call device to execute a corresponding voice call operation; and when the selected target type of the calling conversation is the packet domain voice call, selecting the VoLTE voice call device to execute the corresponding voice call operation.
Specifically, as a preferred implementation, the selecting a target type of the calling session according to the network status includes:
and under the condition that the terminal registers in an IMS network and the signal coverage of the LTE network meets set conditions, selecting packet domain voice calling, otherwise, selecting circuit domain voice calling.
Specifically, when the terminal registers with an IMS network and the signal coverage of the LTE network satisfies a set condition, a VoLTE voice device is selected as a target voice calling device to perform a packet domain voice call.
Wherein, the "otherwise" specifically includes: the method comprises the following steps that when a terminal is not registered with an IMS network, and when the terminal is registered with the IMS network and the signal coverage of an LTE network does not meet set conditions. At this time, the circuit domain voice call is selected. Specifically, the CSFB voice apparatus is selected as the target voice calling apparatus to perform the circuit domain voice call.
The signal coverage of the LTE network does not satisfy the setting condition, and may be determined that at least one of signal parameter values such as reference signal received power RSRP, reference signal received quality RSRQ, and received signal strength indicator RSSI is lower than a set threshold. Otherwise, determining that the signal coverage of the LTE network meets the set conditions.
Step 104: and initiating the calling call according to the target type of the calling call.
As a preferred embodiment, in a case that a target type of a calling call is a circuit domain voice call, initiating the calling call according to the target type of the calling call includes:
selecting a first type target cell from first type cells corresponding to the circuit domain voice call; accessing in the currently selected first type target cell; under the condition that the currently selected first type target cell is successfully accessed, initiating a calling conversation and calling operation; and under the condition that the currently selected first type target cell fails to be accessed, adding 1 to the access failure times, ending the calling conversation when the access times reach a first preset threshold, reselecting another first type target cell when the access times do not reach the first preset threshold, and returning to the step of accessing in the currently selected first type target cell.
In the process, when a circuit domain voice call is initiated, a target cell is selected from the corresponding type cells for access, and after the access of the cell fails, other cells are continuously selected for access attempt again, specifically, the CSFB voice device is used for the purpose of improving the call completing rate by trying as much as possible under the abnormal condition of the 2G/3G cell.
The specific implementation process may include: when the voice type decision device selects the target type of the calling call as the circuit domain voice call, the voice service in the Long Term Evolution (LTE) network can be realized by the circuit domain fallback (CSFB). The method comprises the steps that a voice type decision device sends a circuit domain voice call to a modem protocol side, the modem protocol side initiates an ESR (extended service request) to a network according to the call type, the network sends a redirection message to a terminal after receiving the ESR request, and after receiving the redirection message, the terminal redirects to a 2G/3G network and analyzes corresponding cell information in the redirection message to try to access.
This implementation is illustrated below.
For example, the terminal performs an access attempt in a 2G/3G cell a, and if the terminal can normally access the cell a, a call is initiated and the call is normally performed; if the terminal fails to access in the cell a, such as 2G/3G rach failure, GSM (global system for mobile communications) network IMMEDIATE ASSIGNMENT (immediate assignment command) is rejected by network reject, SERVICE REQUEST is rejected by network reject, LU (location area update) with CSMT/CSMO (circuit domain called/circuit domain calling) parameters fails, such as LU accept signaling is not issued by the network or LU reject is issued by the network, resulting in network anomaly, a second access attempt is made in other cells, such as cell B. If the follow-up fails, other cells can be selected continuously, and N attempts are made. Based on the fact that the time consumption of the 2G/3G calling process is long, in practice, N is generally set to be 2, namely the first preset threshold is 2. The terminal tries to access the cell B again, and if the cell B is accessed normally, the call is initiated; if the access of the cell B fails, the call fails, and the call flow is terminated. In the process, an abnormal retry mechanism is added when the network is accessed in the voice calling process, and the call completing rate is improved.
Wherein, preferably, the method further comprises: and giving a call reliability weight to the cell which is subjected to the access attempt, and recording tracking area identifiers TAC, location areas LA and cell IDs of the current network, wherein the weight of the cell which is successfully accessed is higher than that of the cell which is failed to be accessed, and the weight of the cell is increased when the cell is successfully accessed every time. Correspondingly, in the process of reselecting another first type target cell, the method comprises the following steps: and according to the weight of the call reliability, selecting a first type target cell selected before, a cell with the same tracking area identifier and the same location area as another first type target cell.
Aiming at the cell with the largest weight, the same TAC and the same LA, namely the cell with the highest reliability, which is preferentially selected in the retry process, the problem of single cell abnormity is solved, the call completing rate is effectively improved, and the user experience is improved.
As another preferred embodiment, when the target type of the calling call is a packet domain voice call, the initiating the calling call according to the target type of the calling call includes:
selecting a second type target cell from second type cells corresponding to the packet domain voice call; accessing in the currently selected second type target cell; initiating a calling conversation and calling operation under the condition that the currently selected second type target cell is successfully accessed; and when the access frequency does not reach the third preset threshold, another second type target cell is reselected from the second type cells, and the step of accessing in the currently selected second type target cell is returned.
In the process, when a packet domain voice call is initiated, a target cell is selected from the corresponding type cells for access, when the access of the cell fails, other cells are continuously selected for access attempt again, specifically, the VoLTE voice device is used for performing the access attempt again, so that the call completing rate is improved by trying as much as possible under the abnormal condition of the LTE cell.
The specific implementation process may include: the voice type decision device issues a VoLTE voice call, namely a packet domain voice call is sent to a modem protocol side, and the modem protocol side selects to perform access attempt in an LTE cell A according to the call type. The terminal performs access attempt in an LTE cell A, if the terminal can normally access the cell A, the terminal initiates a call, and the conversation is normally performed; if the terminal fails to access in the cell A, such as LTE rach failure, RRC (radio resource control) establishment REQUEST no response, LTE SERVICE REQUEST is rejected by the network, for example, an IMS network temporary abnormity caused by that the IP multimedia subsystem IMS call can not be carried out currently due to the temporary failure of the core network, the cell is replaced, and the access attempt is selected to continue on the cell B. I.e. to ensure that the attempt continues after failure, but also to ensure that the call is made as far as possible over VoLTE. The terminal makes a second access attempt in LTE cell B. If the follow-up process fails, other cells can be continuously selected, and M attempts are performed, wherein M is generally set to be 3 in the practical process, that is, the third preset threshold is 3. Although the process is tried in the LTE cell for many times, as long as M is reasonably configured, the call establishment experience of the user cannot be influenced by factors such as time delay and the like, and the call completing rate is improved.
Differently, in the present embodiment, when attempting to access multiple LTE cells still fails, based on fast VoLTE call setup, the voice call type is changed, each step in the previous embodiment is executed again, the voice call type is switched from the packet domain call to the circuit domain call, and the CSFB voice call is selected to be performed. When the LTE network is unavailable, the circuit domain voice call is switched to be carried out on the 2G/3G network, so that the voice call can be normally carried out, and the call completing rate is improved.
In the implementation mode, in the voice call execution process, not only an abnormal retry mechanism of the access network is added, but also a mechanism of voice call type reselection is added, so that the call completing rate is further improved, and the user experience is improved.
Wherein, preferably, the method further comprises: and giving a call reliability weight to the cell which is subjected to the access attempt, and recording tracking area identifiers TAC, location areas LA and cell IDs of the current network, wherein the weight of the cell which is successfully accessed is higher than that of the cell which is failed to be accessed, and the weight of the cell is increased when the cell is successfully accessed every time. Correspondingly, in the process of reselecting another second type target cell, the method comprises the following steps: and according to the weight of the call reliability, selecting a second type target cell selected previously, a cell with the same tracking area identifier and the same location area as another second type target cell.
As another preferred embodiment, when the target type of the calling call is a packet domain voice call, the initiating the calling call according to the target type of the calling call includes:
selecting a second type target cell from second type cells corresponding to the packet domain voice call; accessing in the currently selected second type target cell; initiating a calling conversation and calling operation under the condition that the currently selected second type target cell is successfully accessed; and under the condition that the currently selected second type target cell fails to be accessed, adding 1 to the access failure times, ending the calling conversation when the access times reach a second preset threshold, reselecting another second type target cell from the second type cells when the access times do not reach the second preset threshold, and returning to the step of accessing the currently selected target cell.
In the process, when a packet domain voice call is initiated, a target cell is selected from the corresponding type cells for access, when the access of the cell fails, other cells are continuously selected for access attempt again, specifically, the VoLTE voice device is used for performing the access attempt again, so that the call completing rate is improved by trying as much as possible under the abnormal condition of the LTE cell.
The specific implementation process may include: the voice type decision device issues a VoLTE voice call, namely a packet domain voice call is sent to a modem protocol side, and the modem protocol side selects to perform access attempt in an LTE cell A according to the call type. The terminal performs access attempt in an LTE cell A, if the terminal can normally access the cell A, the terminal initiates a call, and the conversation is normally performed; if the terminal fails to access in the cell A, such as LTE rach failure, RRC (radio resource control) establishment REQUEST no response, LTE SERVICE REQUEST is rejected by the network, for example, an IMS network temporary abnormity caused by that the IP multimedia subsystem IMS call can not be carried out currently due to the temporary failure of the core network, the cell is replaced, and the access attempt is selected to continue on the cell B. I.e. to ensure that the attempt continues after failure, but also to ensure that the call is made as far as possible over VoLTE. The terminal makes a second access attempt in LTE cell B. If the follow-up process fails, other cells can be continuously selected, and M attempts are performed, wherein M is generally set to be 3 in the practical process, that is, the third preset threshold is 3. Although the process is tried in the LTE cell for many times, as long as M is reasonably configured, the call establishment experience of the user cannot be influenced by factors such as time delay and the like, and the call completing rate is improved.
Wherein, preferably, the method further comprises: and giving a call reliability weight to the cell which is subjected to the access attempt, and recording tracking area identifiers TAC, location areas LA and cell IDs of the current network, wherein the weight of the cell which is successfully accessed is higher than that of the cell which is failed to be accessed, and the weight of the cell is increased when the cell is successfully accessed every time. Correspondingly, in the process of reselecting another second type target cell, the method comprises the following steps: and according to the weight of the call reliability, selecting a second type target cell selected previously, a cell with the same tracking area identifier and the same location area as another second type target cell.
In the implementation mode, an abnormal retry mechanism of an access network is added in the voice call execution process, so that the call completing rate is improved, and the user experience is improved.
Further, preferably, the terminal calling method in the embodiment of the present invention further includes:
and after the calling call is finished, sending a tracking area position updating request to the network, and updating the network registration state of the terminal.
When the type of the calling call is a circuit domain voice call, after the calling call of the circuit domain is ended, no matter whether the call is connected or not, in order to ensure that the VoLTE registration states of the terminal side and the network side are consistent and the VoLTE residence ratio of the terminal is as large as possible, namely, the network side and the terminal side are both in the VoLTE registration states, after the call is ended, the terminal needs to initiate a tracking area to update TAU and update the terminal state.
