Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. 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 application.
At present, a terminal usually initiates an IMS call request according to a resource reservation state, and when a support condition of a network operator or a network coverage area for resource reservation is uncertain, a resource reservation header field carrying condition of the IMS call request may not match an actual resource reservation support condition of a network, thereby causing an IMS call failure. A first embodiment of the present invention provides an IMS call initiation method, where if a previously sent IMS call request fails to initiate a call, a second attempt is made to send an IMS call request whose resource reservation header carries a status opposite to that of the previous one, as shown in fig. 1, which is a basic flowchart of the IMS call initiation method provided in this embodiment, and the IMS call initiation method includes the following steps:
in this embodiment, the terminal is a terminal supporting an IMS voice service, and when the terminal initiates a call, the call may be initiated through an LTE network, and the service initiated by the terminal is transmitted through the LTE network. When the terminal initiates a call under the IMS, two opposite resource reservation states are preconfigured on the terminal according to different actual application requirements, so as to adapt to different communication scenarios.
It should be noted that, in practical application, the resource reservation state preconfigured on the terminal may be configured already at the time of factory shipment, and then the resource reservation state is defaulted in the subsequent processes; or the resource can be periodically reconfigured, and a configured resource reservation state is kept in a certain period; it is also possible to reconfigure the resource reservation status before each call initiation.
Optionally, in this embodiment, the manner of performing the pre-configuration of the resource reservation state before executing the call initiation procedure of this embodiment each time includes, but is not limited to, the following two ways:
determining the historical support condition of a network operator to which the terminal belongs to the resource reservation in a first mode; and pre-configuring the resource reservation state of the terminal according to the historical support condition of resource reservation.
Specifically, in an embodiment, different network operators have different support conditions for resource reservation, and the same network operator has different support conditions for resource reservation at different times, and in practical application, the network operator to which the terminal belongs refers to the support conditions for resource reservation at a certain time or a certain time period to guide the pre-configuration of the current resource reservation state of the terminal. For example, statistics is performed on the resource reservation support condition of the network operator to which the terminal belongs in the past month, and it is found that the network operator supports resource reservation under most conditions according to the statistical result, then the resource reservation state of the terminal may be preconfigured as the resource reservation open state at present.
Acquiring a network coverage area where the terminal is currently located; determining the historical support condition of a network coverage area for resource reservation; and pre-configuring the resource reservation state of the terminal according to the historical support condition of resource reservation.
Specifically, in practical applications, network coverage areas where the terminal is located are usually different, and deployment situations of network devices at different locations may be different, so that support situations of network reservation for resources in different network coverage areas are different.
102, initiating a first IMS call request according to a resource reservation state; the carrying state of the resource reservation header field of the first IMS call request corresponds to the resource reservation state, and the carrying state of the resource reservation header field comprises a carrying resource reservation header field and a non-carrying resource reservation header field;
in the IMS call origination overall flow of this embodiment, the IMS call request that is originated for the first time may be associated with a resource reservation state preconfigured by the terminal, and a resource reservation header field carrying state of the IMS call request corresponds to the resource reservation state, that is, when the resource reservation state is a resource reservation open state, the resource reservation header field is carried in the transmitted IMS call request, and when the resource reservation state is a resource reservation closed state, the resource reservation header field is not carried in the transmitted IMS call request.
It should be noted that, in this embodiment, the IMS call may be a VoLTE (Voice over LTE) call, the terminal registers to the IMS system, registers to VoLTE, and initiates a VoLTE call request when a Voice call needs to be established.
in this embodiment, when initiating an IMS call request, it does not know the actual support situation of the current operator network or the network coverage area where the operator network belongs to for resource reservation, so that when a terminal initiates a first IMS call request, a situation that is not matched with the actual support situation of the current network for resource reservation may be encountered, thereby causing an IMS call failure.
Specifically, in this embodiment, when an IMS call request whose resource reservation header carries a status matched with a resource reservation status preconfigured by the terminal is initiated, if the call fails, it is indicated that the initiated IMS call request is not matched with an actual support condition of resource reservation by the current network, so as to ensure a call success rate, the embodiment continuously tries to initiate an IMS call request whose resource reservation header carries a status opposite to that of the previous IMS call request, for example, a first IMS call request carries a resource reservation header, and when the call fails, continuously initiates a second IMS call request which does not carry a resource reservation header, so that the initiated IMS call request is matched with an actual support condition of resource reservation by the current network, and the call success rate can be effectively improved.
Optionally, when the call fails, the controlling the terminal initiating the second IMS call request includes: when the call fails, the control terminal initiates a second IMS call request by silent redialing; or, when the call fails, the control terminal performs call failure prompt, and when receiving a call redialing instruction, initiates a second IMS call request.
It should be further noted that, in the present embodiment, when the previous IMS call fails, the manner of continuing to attempt to initiate the IMS call includes, but is not limited to, one of the following two manners, that is, when the previous IMS call fails, directly and automatically triggering the terminal to continue to make the IMS call request; secondly, when the IMS call fails in the previous time, the terminal is not triggered to automatically initiate a second IMS call request, secondly, the call failure is prompted, and if the call failure prompt is obtained from the outside, and a call redialing instruction is fed back according to the call failure prompt feedback, the second IMS call request is initiated according to the instruction. It should be further noted that, in other embodiments, different from the second embodiment, the received call redial instruction does not only indicate to initiate the second IMS call request, that is, the external call redial instruction may include a first call redial instruction to initiate the first IMS call request and a second call redial instruction to initiate the second IMS call request, so that when the first IMS call redial instruction is received, the terminal is triggered to initiate the first IMS call redial instruction again.
Optionally, after controlling the terminal to initiate the second IMS call request, the method further includes: and switching the resource reservation state of the terminal to be opposite to the pre-configured resource reservation state when the call request based on the second IMS call is successful.
Specifically, in this embodiment, if the call initiated based on the first IMS call request fails and the call initiated based on the second IMS call request succeeds, it indicates that the second IMS call request matches the actual support condition of resource reservation by the current network, so that the resource reservation state of the terminal is switched to match the resource reservation header field carrying state of the second IMS call request, that is, the resource reservation state of the terminal is switched to be opposite to the preconfigured resource reservation state, so that when the IMS call initiation procedure is performed again in the subsequent process, and the IMS call request is initiated based on the switched resource reservation state, the actual support condition of resource reservation by the network can be matched, and the success rate of initiating the IMS call in the subsequent process is improved.
Optionally, after controlling the terminal to initiate the second IMS call request, the method further includes: switching the terminal to a communication network capable of processing circuit domain voice call when the call is failed based on the second IMS call request; the control terminal initiates call redialing on the communication network capable of processing circuit domain voice call.
Specifically, in practical applications, for example, the LTE network coverage area of the current user is poor in LTE network signal, or the LTE network is not covered, in this case, a failure in initiating the second IMS call request may be caused, and in order to ensure the voice call requirement of the user, the control terminal falls back to the communication network capable of handling Circuit Switched (CS) voice call, and redials on the CS domain to continue initiating the call request, and attempts to establish the voice call.
It should be noted that the network capable of handling the CS domain voice call is a 2G or 3G network, that is, the target handover network in the embodiment may include any one of the following: GSM network, WCDMA network, TD-SCDMA network, and CDMA network.
Optionally, when there are multiple communication networks capable of handling the cs voice call, switching the terminal to the communication network capable of handling the cs voice call includes: acquiring switching priorities of a plurality of communication networks; determining the communication network with the highest switching priority as a target communication network according to the sequencing result of the switching priority; and switching the terminal to the target communication network.
Specifically, in practical application, a plurality of switchable networks that can be supported by the terminal may be simultaneously provided, for example, the terminal may fall back to 2G or 3G to complete call initiation in this embodiment, and in order to enable the communication network to which the terminal falls back to ensure the communication performance of the terminal, in this embodiment, a communication network with a high switching priority is selected as a target communication network according to priorities of a plurality of selectable communication networks, so as to avoid poor communication performance caused by blind handover, for example, handover failure or poor communication quality.
Optionally, the obtaining the switching priorities of the plurality of communication networks includes: acquiring the network quality of a plurality of communication networks at the current position of the terminal; and respectively determining the switching priorities of the plurality of communication networks according to the network quality and the corresponding relation between the preset network quality and the switching priorities.
Specifically, in this embodiment, the switching priorities of the multiple communication networks may be preset in the terminal, for example, the switching priorities are set by an operator according to experience data or test data, or may be set by the terminal user according to actual usage habits and stored in the terminal. It should be noted that, in order to better fit the current practical application scenario of the user, in this embodiment, it is proposed to determine the handover priority of the communication network according to the network quality of each communication network where the terminal is currently located, for example, the 3G device is not installed in the current location of the terminal, or the installation location of the 3G macro base station is farther from the current location, so that the coverage of the 3G network in the current location is poor, and here, since the 2G macro base station is closer, the 2G network signal is kept at a better level, in this case, the handover priority of the 3G network is designated as a lower priority, while the handover priority of the 2G network is higher, when performing network handover, the 2G network is switched to continue call initiation.
Based on the technical scheme of the embodiment of the application, when the terminal initiates an IMS call, a first IMS call request with a resource reservation header field carrying state matched with that of the terminal is initiated according to a pre-configured resource reservation state, a call is attempted to be established, and if the call fails, a second IMS call request with a resource reservation header field carrying state opposite to that of the first IMS call request is initiated. By implementing the scheme of the application, the IMS call request is adaptively initiated according to the resource reservation state, and if the IMS call request initiated firstly fails to initiate a call, the IMS call request with the resource reservation header carrying state opposite to that before is attempted to be sent again, so that the call failure caused by the corresponding initiation of the IMS call request according to the resource reservation state under the scene of uncertain actual support condition of the network on the resource reservation can be avoided, and the success rate of initiating the IMS call by the terminal under the LTE network is effectively improved.
The method in fig. 2 is a detailed IMS call initiation method according to a second embodiment of the present invention, where the IMS call initiation method includes:
In this embodiment, each time an IMS call origination procedure is executed, the resource reservation state of the terminal is preconfigured according to the historical support condition of resource reservation by the network operator to which the terminal belongs, and in other embodiments, the resource reservation state of the terminal may be preconfigured according to the historical support condition of resource reservation by the network coverage area in which the terminal is currently located.
When a terminal initiates a call under an IMS, two opposite resource reservation states can be preconfigured on the terminal according to different actual application requirements so as to adapt to different communication scenes.
Specifically, in this embodiment, the IMS call may be a VoLTE call, and when a voice call needs to be established, the IMS call is to initiate a VoLTE call request.
It should be noted that, unlike the case where the terminal is directly and automatically triggered to continue to perform the second IMS call request after the first IMS call fails, in other embodiments of this embodiment, the terminal may also be controlled to perform the call failure prompt first when the call fails, and initiate the second IMS call request when the call redialing instruction is received.
And step 206, when the call is successfully requested based on the second IMS call, switching the resource reservation state of the terminal to be opposite to the pre-configured resource reservation state.
If the call initiated based on the second IMS call request is successful, it indicates that the second IMS call request matches the actual support situation of the resource reservation by the current network, and in this embodiment, the resource reservation state of the terminal is switched to match the resource reservation header carrying state of the second IMS call request, so that when the IMS call initiation procedure is subsequently executed again, and the IMS call request is initiated based on the switched resource reservation state, the resource reservation header carrying state can match the actual support situation of the resource reservation by the network, thereby improving the success rate of the subsequent IMS call initiation.
And step 207, when the call is failed based on the second IMS call request, switching the terminal to the communication network capable of processing the circuit domain voice call, and controlling the terminal to initiate call redialing on the communication network capable of processing the circuit domain voice call.
In practical applications, if the LTE network signal of the coverage area of the network where the current user is located is poor or the LTE network is not covered, in such a case, a failure in initiating the second IMS call request may be caused, and in order to ensure the voice call requirement of the user, in this embodiment, the control terminal falls back to the communication network capable of handling the CS domain voice call, and redials over the CS domain to continue initiating the call request, so as to attempt to establish the voice call.
The embodiment of the application discloses an IMS call initiating method, when a terminal initiates an IMS call, a first IMS call request with a resource reservation head domain carrying state matched is initiated according to a pre-configured resource reservation state, a call is tried to be established, and if the call fails, a second IMS call request with the resource reservation head domain carrying state opposite to that of the first IMS call request is initiated. By implementing the scheme of the application, the IMS call request is adaptively initiated according to the resource reservation state, and if the IMS call request initiated firstly fails to initiate a call, the IMS call request with the resource reservation header carrying state opposite to that before is attempted to be sent again, so that the call failure caused by the corresponding initiation of the IMS call request according to the resource reservation state under the scene of uncertain actual support condition of the network on the resource reservation can be avoided, and the success rate of initiating the IMS call by the terminal under the LTE network is effectively improved.
