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 some, not all, embodiments of the present invention. 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.
Some terms involved in the embodiments of the present invention are explained below for convenience of understanding:
and (3) call holding: the mobile user who is in the process of communication can temporarily interrupt the original telephone of data and make a new telephone, and simultaneously keeps contact with the original telephone; when the original call needs to be replied, the newly-made call is kept, and then the call with the original call party is continued, namely, the two calls can be selected and switched by operating the keys of the mobile phone, and the call with the call party can be respectively or simultaneously ended.
There may be two calls that the electronic device is in connection with: 1. an active call (active call) is a call in a normal state in which a call is connected in two directions; 2. a hold call refers to a call in which one party is on one way, and the user on hold typically hears a piece of background music played on the network.
In the related art, as shown in fig. 1, when the electronic device 1 and the electronic device 2 enter the call holding state, the electronic device 1 transmits an UPDATE request message to the electronic device 2 through the network device, where a parameter a of the request message is sendonly, and the UPDATE request message is used to make the electronic device 2 enter the call holding state, and then, after receiving the request message, the electronic device 2 transmits an UPDATE response message to the electronic device 1 through the network device, where a parameter a of the response message is recurvon (receive only). Therefore, the electronic device 1 and the electronic device 2 are in a call holding state, at this time, the electronic device 1 may send media information, the electronic device 2 may receive the media information, the network device may receive the media information of the electronic device 1, but does not forward the media information to the electronic device 2, but sends a prompt tone to the electronic device 2 to prompt that the electronic device is in the call holding state. After that, the network device sends RTCP messages periodically (typically 20 seconds or 3600 seconds) to the electronic device 1 and the electronic device 2, respectively, so that the electronic device 1 and the electronic device 2 are continuously in a call-hold state.
When the electronic device 2 actively cuts off the call with the electronic device 1, the electronic device 2 sends an interrupt message to the network device, so that the network device can acquire the call state of the electronic device 2. Then, the network device stops sending the RTCP message to the electronic device 1, and when the electronic device 1 does not receive the RTCP message sent by the network device within a preset period, the electronic device 1 actively disconnects the call connection with the electronic device 2 in the call holding state of the electronic device 1.
When the electronic device 1 and the electronic device 2 are in a call hold state, if the electronic device 2 suddenly crashes or drops, the interrupt message cannot be sent to the network device, and at this time, the network device still sends the RTCP message to the electronic device 1. In this way, the electronic device 1 cannot disconnect the call connection with the electronic device 2 in time, and the call cost of the user is wasted.
In order to solve the above problem, embodiments of the present invention provide a call holding method and an electronic device, which can cut off a call connection in time when one of two parties in call holding suddenly crashes or drops, so as to reduce user loss and improve user experience.
The parameter a in the UPDATE message mentioned in the embodiment of the present invention represents the media direction of the electronic device sending the message, and the value of the parameter a may be sendonly, inactive, revonly and sendrecv. Wherein, if the direction of a certain media stream is requested to be sendonly, the direction of the corresponding media in the response must be rechonly; if the direction of a certain media stream is requested to be recvon, the direction of the corresponding media in the response must be sendonly; if the direction of a certain media stream is requested to be sendecv, the direction of the corresponding media in the response can be one of sendecv/sendonly/revonly/inactive; if the direction of a request for a media stream is inactive, the direction of the corresponding media in the response must be inactive.
It should be noted that "/" in this context means "or", for example, A/B may mean A or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.
It should be noted that "a plurality" herein means two or more than two.

For example, the first and second detection requests are for distinguishing between different detection requests, rather than for describing a particular order of detection requests.
The main execution body of the call holding method provided in the embodiment of the present invention may be the electronic device (including a mobile terminal device and a non-mobile terminal device), or may also be a functional module and/or a functional entity capable of implementing the call holding method in the electronic device, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited. The following takes an electronic device as an example to exemplarily explain the call holding method provided by the embodiment of the present invention.
The electronic device in the embodiment of the present invention may be a terminal device, or may also be a User Equipment (UE). The terminal device may be a mobile terminal device or a non-mobile terminal device. The mobile terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
The electronic device in the embodiment of the present invention may be a terminal device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.
The following describes a software environment applied to the call holding method provided by the embodiment of the present invention, taking an android operating system as an example.
Fig. 2 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 2, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.
The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the call holding method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 2, so that the call holding method may operate based on the android operating system shown in fig. 2. That is, the processor or the electronic device may implement the call holding method provided by the embodiment of the present invention by running the software program in the android operating system.
The call holding method according to the embodiment of the present invention is described below with reference to a flow chart of the call holding method shown in fig. 3, where fig. 3 is a flow chart of the call holding method according to the embodiment of the present invention, and the flow chart includes steps S201 to S202:
s201, under the condition that the first electronic device and the second electronic device are in a conversation holding state, the first electronic device sends a first detection request to the second electronic device.
The first detection request is used for detecting the current call state of the second electronic equipment.
Optionally, step S201 may include the following steps: under the condition that the first electronic device and the second electronic device are in a conversation holding state, the first electronic device sends a first detection request to the second electronic device at intervals of preset time.
For example, since either one of the two parties on hold may suddenly crash or drop, in step S201, the first electronic device and the second electronic device alternately transmit a first detection request for detecting the current call state of the other party according to the above steps at preset time intervals. Therefore, when the first electronic equipment or the second electronic equipment breaks down, the party in conversation with the first electronic equipment and maintaining conversation with the second electronic equipment can acquire the current conversation state of the party in conversation and cut off the conversation connection between the first electronic equipment and the second electronic equipment in time.
Optionally, the first detection request is an UPDATE message based on an SDP protocol.
For example, when the first electronic device transmits the first detection request, in order to ensure that the first detection response of the second electronic device can be received, the first detection request includes: the parameter a in the UPDATE message is inactive.
S202, if the first electronic equipment does not receive the first detection response sent by the second electronic equipment within the first preset time, the first electronic equipment disconnects the call connection with the second electronic equipment.
Illustratively, the first predetermined time may be 10 seconds in consideration of network delay and an operation state of the second electronic device (e.g., whether a stuck condition occurs or not). That is, when the first electronic device does not receive the first detection response sent by the second electronic device within 10 seconds after sending the first detection request to the second electronic device, the first electronic device determines that the second electronic device has a failure, and disconnects the call connection with the second electronic device.
Optionally, in the step S202, the process of disconnecting the call connection between the first electronic device and the second electronic device may further include the following steps S202a and S202 b:
s202a, if the first electronic device does not receive the first detection response sent by the second electronic device within the first preset time, the first electronic device sends a second detection request to the second electronic device.
And the second detection request is used for detecting the current call state of the second electronic equipment.
For example, in order to more accurately determine whether the second electronic device suddenly crashes or drops, a secondary detection mechanism is provided in an embodiment of the present application, that is, when the first electronic device does not receive the first detection response sent by the second electronic device within a preset time, the first electronic device sends a second detection request to the second electronic device.
S202b, if the first electronic device does not receive the second detection response sent by the second electronic device within the second preset time, the first electronic device disconnects the call connection with the second electronic device.
For example, the second preset time may be 10 seconds, considering the network delay and the operation state of the second electronic device (e.g., whether the second electronic device is stuck or not). That is, when the first electronic device does not receive the second detection response sent by the second electronic device within 10 seconds after sending the second detection request to the second electronic device, the first electronic device determines that the second electronic device is faulty, and disconnects the call connection with the second electronic device.
Optionally, in the step S201, after the first electronic device sends the first detection request to the second electronic device, the method may further include the following steps S201a and S201 b:
s201a, if the first electronic device receives the first detection response sent by the second electronic device within the first preset time, the first electronic device sends a second detection request to the second electronic device.
And the second detection request is used for detecting the current call state of the second electronic equipment.
For example, after the second electronic device receives the first detection request sent by the first electronic device, since the first detection request is an UPDATE message based on an SDP protocol and a parameter a in the UPDATE message is inactive, the first detection response sent by the second electronic device is an UPDATE message based on the SDP protocol and the parameter a in the UPDATE message is inactive according to the third generation partnership project (3 GPP) protocol specification.
S201b, if the first electronic device receives a second detection response sent by the second electronic device within a second preset time, the first electronic device maintains a call connection with the second electronic device.
For example, after the second electronic device receives the second detection request sent by the first electronic device, since the second detection request is an UPDATE message based on an SDP protocol and a parameter a in the UPDATE message is sendorly, the second detection response sent by the second electronic device is an UPDATE message based on the SDP protocol and the parameter a in the UPDATE message is revonly according to the 3GPP protocol specification.
Note that, in step S201a, the first electronic device sends an UPDATE message with parameter a being inactive to the second electronic device, and the second electronic device replies the UPDATE message with parameter a being inactive to the first electronic device, at this time, the call holding state of the first electronic device and the second electronic device has changed, so in order to recover the call holding state, the first electronic device needs to send an UPDATE message with parameter a being sendonly to the second electronic device.
For example, for convenience of understanding, as shown in fig. 4, taking a first electronic device as the electronic device 1 and a second electronic device as the electronic device 2 as an example, a flow of the call holding method provided in the embodiment of the present application is described, where the method includes the following two flows, which are flow 1 and flow 2 respectively, where:
the process 1 is as follows: when the electronic device 1 and the electronic device 2 are in a normal call holding state (that is, the electronic device 1 and the electronic device 2 do not have a sudden crash or a failure of dropping), a flow of maintaining call holding between the electronic device 1 and the electronic device 2 is performed.
The process 2 is as follows: when the electronic device 1 and the electronic device 2 are in a call holding state, and the electronic device 2 suddenly crashes or is disconnected, the electronic device 1 determines a call state of the electronic device 2.
Specifically, as shown in fig. 4, the process 1 includes the following steps:
s300a, the electronic device 1 sends a first detection request to the electronic device 2. Wherein, the parameter a in the UPDATE message in the first detection request is inactive.
S300b, after receiving the first detection request sent by the electronic device 1 within the first preset time, the electronic device 2 sends a first detection response to the electronic device 1. Wherein, the parameter a in the UPDATE message in the first detection response is inactive.
S300c, after receiving the first detection response sent by the electronic device 2 within the second preset time, the electronic device 1 sends a second detection request to the electronic device 2. Wherein, the parameter a in the UPDATE message in the second detection request is sendonly.
S300d, after receiving the second detection request sent by the electronic device 1 within the second preset time, the electronic device 2 sends a second detection response to the electronic device 1. Wherein, the parameter a in the UPDATE message in the second detection response is recurvon.
After receiving the second detection response sent by the electronic device 2 within the second preset time, the electronic device 1 determines that the electronic device 2 is in a normal call holding state, and then continues to hold the call connection with the electronic device 2.
Specifically, as shown in fig. 4, the process 2 includes the following steps:
s301a, the electronic device 1 sends a first detection request to the electronic device 2. Wherein, the parameter a in the UPDATE message in the first detection request is inactive.
S301b, when the electronic device 1 does not receive the first detection response sent by the electronic device 2 within the first preset time, sending a second detection response to the electronic device 2. Wherein, the parameter a in the UPDATE message in the second detection request is sendonly.
S301c, when the electronic device 1 does not receive the second detection response sent by the electronic device 2 within the second preset time, determining that the electronic device 2 has a fault, and disconnecting the call with the electronic device 2.
Note that, the above-mentioned flow 1 and flow 2 are flows executed periodically, and when the flow is completed, the parameter a of the UPDATE message sent by the electronic device 1 is sendonly, and the parameter a of the UPDATE message sent by the electronic device 2 is recurvon, and at this time, the state of the electronic device 2 is that only reception is not sent, so when a new flow is started, the electronic device 1 needs to send an UPDATE message with parameter a being inactive to the electronic device 2 to change the state of the electronic device 2 so that it can respond to the UPDATE message sent by the electronic device 1. Since the detection request (e.g., the first detection request and the second detection request) sent by the electronic device 1 to the electronic device 2 and the detection response (e.g., the first detection response and the second detection response) sent by the electronic device 2 to the electronic device 1 are both forwarded by the network device, the response message received by the electronic device 1 is necessarily sent by the electronic device 2. If the electronic device 2 crashes or drops suddenly, the electronic device 1 will not receive any response, and therefore, the call state of the electronic device 2 can be determined accordingly.
In the embodiment of the present invention, the call holding methods shown in the above-mentioned method drawings are all exemplarily described with reference to one drawing in the embodiment of the present invention. In specific implementation, the call holding method shown in each method drawing can also be implemented by combining any other drawing which can be combined and is illustrated in the above embodiments, and details are not described here.
According to the call keeping method provided by the embodiment of the invention, the first electronic equipment sends the detection request to the second electronic equipment, and the second electronic equipment can be found to be out of order and disconnected from the call connection with the second electronic equipment in time according to whether the first electronic equipment can receive the detection response sent by the second electronic equipment within the preset time, so that the call charge loss of a user is reduced, and the call experience of the user is improved.
