The Long Term Evolution Voice-over-Term Evolution (VoLTE) is a high-speed wireless communication standard for mobile phones and data terminals, and the most direct feeling brought by the VoLTE technology to users is that the on-waiting time is shorter, and the Voice-video call effect is higher in quality and more natural. For operators, deploying VoLTE means opening the way to mobile broadband voice evolution.

Because the mobile phone and the mobile phone are used for communicating, in order to realize VoLTE communication, the mobile phones of all parties and the network conditions of the network side are required to meet the requirement of VoLTE communication, and the communication in the mode of VoLTE communication can be ensured. When the VoLTE call is started, icons such as HD/HD+ and the like are displayed on a display screen (such as a signal bar) of the mobile phone during the call, so that the current call is a high-definition call. For the operator, in order to ensure the user experience, the operator wants to display a call state identifier (such as HD/hd+ or the like) icon on each call party when the network quality used by each call party meets a certain requirement. However, since the network quality of different operator networks is different, the mobile phone may not accurately display the HD/hd+ icons.

Detailed Description

Because the mobile phone and the mobile phone are used for communicating, in order to realize VoLTE communication, the mobile phones of all parties and the network conditions of the network side are required to meet the requirement of VoLTE communication, and the communication in the mode of VoLTE communication can be ensured. When the VoLTE call is started, icons such as HD/HD+ and the like are displayed on a display screen (such as a signal bar) of the mobile phone during the call, so that the current call is a high-definition call. For the operator, in order to ensure the user experience, the operator wants to display icons such as HD/hd+ on each party of the call when the network quality used by each party of the call meets certain requirements. That is, in the case where there is no way to secure the network condition, the parties to the call do not display icons such as HD/hd+, that is, the icon display matches the actual situation of the call.

However, since different operators have different network construction capabilities, the network quality of different operators may also be different under the same conditions. For example, operator a and operator B also support 4G networks, but the 4G network of operator a may not meet a stable VoLTE call with poorer network quality than the 4G network of operator B. The mobile phone only needs to open the VoLTE call function, and then icons such as HD/HD+ are displayed in the call process, instead of determining whether to display the icons such as HD/HD+ according to the actual network condition in the call process. Therefore, the mobile phone in the related art may not accurately display icons such as HD/hd+. If the actual network quality in the call process can not meet the VoLTE call, the mobile phone displays icons such as HD/HD+ and the like, so that the illusion that the user is currently enjoying the VoLTE call, but the actual call quality can not meet the standard of the VoLTE call is brought, and poor call experience is brought to the user.

Based on the above, the embodiment of the application provides a call method. The method can be applied to an electronic device. The electronic device supports the establishment of VoLTE mobile sessions with other electronic devices over a mobile communications network. In the method, in the process of establishing mobile communication between electronic equipment, whether the network quality meets the quality condition of VoLTE communication is determined according to the highest coding and decoding type which can be supported for use by the mobile communication and the information of operators of all parties of the communication. If yes, displaying the HD call icon on a display screen of the electronic equipment. And the electronic equipment determines that the network quality of the current call does not meet the quality condition of the VoLTE call, and the electronic equipment does not display the HD call icon. Therefore, the problem that the electronic equipment displays the HD call icon under the condition that the actual network quality is poor and the VoLTE call cannot be satisfied, namely the display is inconsistent with the actual situation, so that poor call experience is brought to a user can be avoided.

In some embodiments, the first electronic device and the second electronic device are the highest codec type and operator information obtained from the network side. Corresponding to the call method applied to the end side, the embodiment of the application also provides a call method applied to the network side. And the network side respectively receives the operator information and the encoding and decoding capability reported by the first electronic equipment and the second electronic equipment in the process of establishing the mobile communication between the first electronic equipment and the second electronic equipment. And then the network side determines the highest coding and decoding type and the operator information of each party of the mobile call according to the coding and decoding capabilities of the first electronic equipment and the second electronic equipment. And then the network side sends the highest encoding and decoding type and the information of the operator to the first electronic equipment and the second electronic equipment.

As shown in fig. 1, taking a call between two parties as an example, the first electronic device may be a mobile phone 1, and the second electronic device may be a mobile phone 2. The mobile phone 1 and the mobile phone 2 establish a mobile call through a mobile communication network. When the mobile phone 1 and the mobile phone 2 establish a mobile call, data sent by the mobile phone 1 is transmitted to the core network 3 through the base station 4, and the core network 3 transmits the data to the mobile phone 2 through the base station 5. Similarly, the mobile phone 2 transmits data to the mobile phone 1, and may also realize transmission sequentially through the base station 5, the core network 3 and the base station 4. The mobile phone 1 and the mobile phone 2 respectively acquire the highest coding and decoding type and the operator information of each party of the mobile phone. It should be appreciated that in other embodiments, a call may be made by multiple parties (more than three parties). The base station 4 and the base station 5 may be two different base stations or may refer to the same base station. The core network 3 may comprise only one core network or may comprise two different core networks.

For example, when the operators corresponding to the mobile phone 1 and the mobile phone 2 are operators within the same area, only one base station and one core network may be involved when the mobile phone 1 and the mobile phone 2 perform mobile communication. If the operators corresponding to the mobile phone 1 and the mobile phone 2 are the same but not in the same area, or if the operators corresponding to the mobile phone 1 and the mobile phone 2 are different, two or more base stations and core networks may be involved in the mobile communication between the mobile phone 1 and the mobile phone 2. The regional scope may refer to a regional scope divided by an operator.

Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

The embodiment of the application provides a call method which is applied to a scene of mobile call between mobile phones, wherein the mobile phones need to combine the highest call coding and decoding capability supported by the mobile call and the operator information of each party of the mobile call to judge the network quality of the current call. Then the mobile phone decides whether to display the HD call icon on the mobile phone display screen. In this way, the HD call icon is displayed only when the network quality of the current call is ensured to meet the requirements, so that the HD call icon is displayed in accordance with the actual situation. Therefore, the problem that the HD call icon is displayed under the condition that the network quality of the call cannot be ensured, and poor experience is brought to the user is avoided.

Technical terms that may be involved in the embodiments of the present application are described below.

HD refers to an image or video with a vertical resolution of 720 or more, also referred to as a high-definition image or high-definition video. Hd+ is somewhat higher relative to HD resolution. After the VoLTE high-definition voice function is started, an icon of 'HD/HD+' is displayed on a signal bar of a display screen, and the mobile phone has the following functions: the system does not disconnect the cellular network during voice call, so as to ensure that other application programs can normally use the mobile data; the call waiting time can be shortened, and the audio and video call quality can be improved.

The core network is responsible for the dispatching of the communication network, the connection of the telephone and the realization of basic service in network communication.

An operator refers to a provider that provides network services.

The mobile communication network is used for realizing communication between the mobile subscriber and the fixed telephone subscriber or between the mobile subscribers.

The following will describe in detail the call method provided in the embodiment of the present application by taking a call between the mobile phone 1 and the mobile phone 2 as an example with reference to the accompanying drawings. It should be understood that the method of the present application may also be applicable to communications between more electronic devices, such as 3 electronic devices or more than 3 electronic devices talking, etc.

Fig. 3 is a flow chart of a call method according to an embodiment of the application. The method comprises S301-S318, wherein:

s301, the mobile phone 1 determines to establish a mobile call with the mobile phone 2.

In some embodiments, the handset 1 may determine to establish a mobile call with the handset 1 in response to a user triggering an operation to dial the mobile call to the handset 2. Or, when the mobile phone 2 dials the mobile phone 1, it may be determined that the mobile phone 1 and the mobile phone 2 establish a mobile phone call.

S302, in the process of establishing mobile communication between the mobile phone 1 and the mobile phone 2, the mobile phone 1 acquires the first encoding and decoding capability of the mobile phone 1.

It should be understood that in the embodiment of the present application, the encoding capability of the handset 1 is denoted as the first encoding capability.

The mobile phone 1 and the mobile phone 2 establish a mobile call, and specifically, the mobile phone 1 can call the mobile phone 2 to request to establish a mobile call with the mobile phone 2, that is, the mobile phone 1 initiates a mobile call connection request to the mobile phone 2. The mobile phone 2 can also call the mobile phone 1 to request to establish mobile communication with the mobile phone 1, i.e. the mobile phone 2 initiates a mobile communication connection request to the mobile phone 1. The method for establishing mobile phone 1 and mobile phone 2 may refer to the description in the conventional technology, and the embodiments of the present application are not described herein.

In the embodiment of the application, the coding and decoding capability of the mobile phone represents the total coding and decoding types supported by the mobile phone. For example, the first codec capability of the handset 1 represents the full amount of codec types supported by the handset 1.

In the application, the full-volume coding and decoding type can specifically comprise the coding and decoding type of the mobile phone supporting the audio data and the coding and decoding type of the mobile phone supporting the video data. The codec type of the mobile phone may specifically include: g.711, g.723, g.726, g.729, internet low bit Rate coding (internet lowbitrate codec, ILBC), stimulated linear predictive coding (QualComm Code Excited Linear Predictive, QCELP), EVRC, and Adaptive Multi-Rate coding (AMR). The AMR coding types may include, among others, AMR Narrowband (NB) coding, AMR Wideband (WB) coding, and AMR-wb+ coding types, etc. It should be understood that the above codec types are examples only, and in other embodiments, the codec types of the mobile phone may also include other codec types.

In some embodiments, the bandwidths and sampling frequencies supported by the different codec types are not the same. Illustratively, the AMR-NB coding type supports a voice bandwidth in the range of 300-3700Hz,8KHz sampling frequency; the AMR-WB supported voice bandwidth ranges from 50-7000Hz,16KHz sampling frequency.

S303, the mobile phone 1 reports the first encoding and decoding capability to the core network 3 through the base station 4.

In some embodiments, the step S303 specifically includes the mobile phone 1 sending the first codec capability to the base station 4, and the base station 4 forwarding the first codec capability to the core network 3.

S304, the core network 3 receives the first coding and decoding capability reported by the mobile phone 1 through the base station 4.

Similarly to the mobile phone 1, in the process of establishing a mobile call between the mobile phone 1 and the mobile phone 2, the mobile phone 2 also obtains the coding and decoding capabilities of the mobile phone 2, and reports the coding and decoding capabilities of the mobile phone 2 to the core network 3; as in S305-S307.

S305, in the process of establishing mobile communication between the mobile phone 1 and the mobile phone 2, the mobile phone 2 acquires the second encoding and decoding capabilities of the mobile phone 2.

It should be understood that in the embodiment of the present application, the encoding capability of the handset 2 is denoted as the second encoding capability.

S306, the mobile phone 2 reports the second encoding and decoding capability to the core network 3 through the base station 5.

S307, the core network 3 receives the second coding and decoding capability reported by the mobile phone 2 through the base station 5.

It should be understood that, the specific process of acquiring and reporting the second codec capability by the mobile phone 2 is similar to the process of acquiring and reporting the first codec capability by the mobile phone 1, which is not described herein. The processes of S302-S304 and S305-S307 may be performed simultaneously, S302-S304 may be performed first and S305-S307 may be performed second, or S305-S307 may be performed first and S302-S304 may be performed second. The application is not limited to the order of S302-S304 and S305-S307.

In order to ensure that the mobile call parties can perform the VoLTE call, not only the electronic devices used by the mobile call parties need to support the VoLTE call, but also the network side (i.e., the core network 3 in the embodiment of the present application) needs to support the VoLTE call. Therefore, in addition to acquiring the codec capabilities of the handsets 1 and 2, it is also necessary to acquire the codec capability of the core network 3 and determine whether the codec capability of the core network 3 satisfies the requirement of VoLTE call.

And S308, the core network 3 acquires the third coding and decoding capability of the core network 3.

It should be understood that in order to distinguish from other words, in the embodiment of the present application, the encoding capability of the core network 3 is denoted as a third encoding capability.

The codec capability of the core network indicates the type of codec supported by the core network. As can be seen from the above description, the core network 3 may comprise one core network or two core networks. When the core network 3 comprises a core network, the core network 3 obtains a third codec capability of the core network 3 itself; i.e. the core network performs S308 described above. When the core network 3 comprises two core networks (e.g. a first core network and a second core network), the third codec capability comprises the codec capability of the first core network and the codec capability of the second core network. In this embodiment, the S308 may specifically be that the first core network obtains the codec capability of the first core network, and the second core network obtains the codec capability of the second core network.

In some embodiments, the core network 3 may determine the highest codec type used by the mobile communication support according to the first codec capability, the second codec capability and the third codec capability; as in S309.

S309, the core network 3 determines the highest coding type used by the mobile call support according to the first coding and decoding capability, the second coding and decoding capability and the third coding and decoding capability.

The highest codec type used in the mobile phone support may be the highest codec type used in the mobile phone support, among the codec types supported by the mobile phone 1, the mobile phone 2 and the core network 3, which are commonly supported by the three codec types. The highest codec type may specifically represent one of all codec types with the highest supported bandwidth.

In some embodiments, the first codec capability, the second codec capability, and the third codec capability represent the full amount of codec capabilities supported by the handset 1, the handset 2, and the core network 3, respectively. Further, the above S309 may specifically determine, by the core network 3, an intersection of the full codec capabilities of the mobile phone 1, the mobile phone 2, and the core network 3, and take a codec type with the highest supported bandwidth in the intersection as the highest codec type used for supporting the mobile phone call. In some embodiments, the above-described procedure of S309 may also be referred to as a procedure in which the core network 3 negotiates to determine the codec type used for the mobile session.

As can be seen from the above description, the core network 3 may comprise one core network or two core networks. When the core network 3 includes a core network, the above S309 is performed by the core network.

In some embodiments, when the core network 3 includes a first core network and a second core network, S309 described above may be performed by either one of the core networks. In some embodiments, when the core network 3 includes the first core network and the second core network, S309 may also be performed by the core network corresponding to the end side that initiates the mobile session connection request. For example, when the mobile phone 1 requests to make a mobile call with the mobile phone 2, S309 is executed by the first core network corresponding to the mobile phone 1 and the base station 4. When the mobile phone 2 requests to make a mobile call with the mobile phone 1, S309 is executed by the second core network corresponding to the mobile phone 2 and the base station 5.

Further, in some embodiments, in the embodiment where the core network 3 includes a first core network and a second core network, taking the first core network to execute S309 as an example, the S309 may specifically include: the first core network negotiates the encoding and decoding capability of the first core network with the first encoding and decoding capability, and determines a fourth encoding and decoding capability. Then, the first core network acquires a fifth codec capability determined by the second core network. The first core network determines the highest codec capability according to the fourth codec capability and the fifth codec capability. Wherein the fifth codec capability is determined by the second core network based on the codec capability of the second core network and the second codec capability.

Alternatively, in other embodiments, taking the first core network as an example of S309, S309 may also include the first core network acquiring the first codec capability and the second codec capability of the first core network, and determining the highest codec type for the first codec capability and the second codec capability of the first core network, and the codec capability of the first core network and the codec capability of the second core network. It should be appreciated that in other embodiments, the above method may also be negotiated by a second one of the core networks 3 to determine the highest codec type.

Further, after negotiating to determine the highest codec type used in the mobile phone support, the core network 3 sends the highest codec type to the mobile phone 1 and the mobile phone 2 respectively.

In addition, in order that each party in the mobile call can determine whether to display the HD call icon on the display of the mobile phone in combination with the operator information and the highest codec type used by each party in the mobile call, the core network 3 needs to notify each party in the mobile call of the operator information of each party in the mobile call.

S310, the core network 3 acquires a first operator identifier corresponding to the mobile phone 1 and a second operator identifier corresponding to the mobile phone 2.

Part of the mobile phones support the simultaneous installation of more than two Subscriber identity module (subscnber) IdentityModule, SIM cards. More than two SIM cards installed in the same mobile phone can belong to the same operator or can belong to different operators. Therefore, when the core network 3 obtains the first operator identifier corresponding to the mobile phone 1, specifically, obtains the operator identifier corresponding to the operator of the SIM card used by the mobile phone 1 when the mobile phone is established.

Because the mobile phone 1 and the mobile phone 2 establish the mobile phone call, the core networks involved in the communication of the mobile phone call parties are all the core networks of the operators corresponding to the mobile phone, so the core network 3 can obtain the operator identifier corresponding to the core network 3 itself as the operator identifier of the mobile phone.

In some embodiments, the core network 3 includes a core network, which indicates that the operators corresponding to the mobile phone 1 and the mobile phone 2 are the same operator. In S310, the core network 3 obtains the operator identifier corresponding to the core network 3, and the operator identifier is respectively used as the first operator identifier of the mobile phone 1 and the second operator identifier of the mobile phone 2.

In other embodiments, the core network 3 includes a first core network and a second core network, and the step S310 specifically includes: the first core network acquires an operator identifier corresponding to the first core network as a first operator identifier of the mobile phone 1; the second core network obtains the operator identifier corresponding to the second core network as the second operator identifier of the mobile phone 2.

S311, the core network 3 sends the highest coding and decoding type and the operator information of each mobile call party to the mobile phone 1 through the base station 4.

S312, the core network 3 sends the highest coding and decoding type and the operator information of each mobile call party to the mobile phone 2 through the base station 5.

In some embodiments, the process of the core network 3 sending the highest codec type and the operator information of each party of the mobile phone call to the mobile phone 1 and the mobile phone 2 respectively may be a step newly added to the core network 3 based on the original communication flow.

In other embodiments, the core network 3 sends the highest codec type and the operator information of each mobile phone call party to the mobile phone 1 and the mobile phone 2, respectively, specifically by carrying and sending the highest codec type and the operator information of each mobile phone call party in the call setup signaling of the operator. The call establishment signaling is used for the core network to transmit data to the mobile phone. In the embodiment of the application, an extension field is established in the call establishment signaling, and the extension field carries the highest coding and decoding type and the operator information of each party of the mobile call. Thus, the process of sending the highest coding and decoding type and the operator information of each mobile call party to the mobile phone 1 and the mobile phone 2 by the core network 3 can be realized in the original communication process without adding a new process. The call establishment signaling of the operator is specifically used for transmitting interaction information, such as time, of each party of the mobile call; the call setup signaling of the operator may be call signaling or the like, for example. It should be understood that the above-mentioned call setup signaling of the operator is only an example, and in other embodiments, the call setup signaling of the operator may be other signaling.

It should be understood that the above-described processes of S311 and S312 may be performed simultaneously, S311 may be performed first and S312 may be performed second, or S312 may be performed first and S311 may be performed second. The application is not limited to the sequence of S311 and S312.

In some embodiments, the operator information sent by the core network 3 to each party of the mobile call may specifically be the operator identifier corresponding to each other party. The operator identification is used to characterize an operator used by a party in the mobile call when setting up the mobile call. Further, in this embodiment, any one of the mobile phone call parties determines whether to display the HD phone call icon according to the operator identifier of the operator used by the other mobile phone call party to establish the mobile phone call. In the embodiment of the present application, taking mobile phone 1 and mobile phone 2 as examples, the core network 3 may send the operator identifier corresponding to the mobile phone 2 to the mobile phone 1 and send the operator identifier corresponding to the mobile phone 1 to the mobile phone 2, respectively. As shown in fig. 4A, the S311 may specifically include S311a, and the S312 may specifically include S312a:

s311a. the core network 3 sends the highest codec type and the second operator identity to the handset 1 via the base station 4.

In an embodiment where the core network 3 includes a first core network and a second core network, S311a may specifically include: the first core network receives the second operator identification from the second core network, and the first core network sends the highest codec type and the second operator identification to the handset 1 through the base station 4.

S312a. the core network 3 sends the highest codec type and the first operator identity to the handset 2 via the base station 5.

In the embodiment where the core network 3 includes the first core network and the second core network, taking the mobile phone 1 requesting to make a mobile call with the mobile phone 2 as an example, the first core network performs S309 above. S312a may specifically include the first core network sending the highest codec type and the first operator identifier to the second core network, and the second core network sending the highest codec type and the first operator identifier to the handset 2 through the base station 5.

In some embodiments, different operators may be represented by different operator numbers. For example, the operator identifier corresponding to the a operator is set to 10110011 1011 0111,B operator identifier corresponding to 10110011 1011 0110,C operator identifier is set to 10110011 1011 0101, and so on. It should be appreciated that the above operator identification is merely an example and is not representative of actual situations; in other embodiments, the operator identification may be provided in other forms as well.

In the technical scheme provided by the embodiment of the application, the core network 3 respectively sends the highest coding and decoding type which can be used by the mobile call and the operator identification corresponding to other call parties to each party, so that each party (the mobile phone 1 and the mobile phone 2) of the mobile call can automatically judge whether the HD call icon needs to be displayed or not. Therefore, in the mobile communication process, the mobile phone can determine whether to display the icon of the HD communication icon according to the actual network condition, so that the display of the HD communication icon accords with the actual condition. And displaying the HD icon on the mobile phone display screen when the current network quality is determined to meet the VoLTE call condition. The problem that the actual conversation quality can not reach the VoLTE conversation quality due to the fact that the HD icon is displayed is avoided, and poor experience is brought to a user.

Alternatively, in other embodiments, the operator information sent by the core network 3 to each party of the mobile call may also be that the core network 3 determines whether the operator used by each party of the mobile call meets the requirement of VoLTE call on the operator, so as to obtain the operator comparison result. And then the core network 3 sends the operator comparison result to each terminal of the mobile call. Therefore, each terminal of the mobile call can determine whether to display the HD call icon according to the operator comparison result and the highest coding and decoding type. As shown in fig. 4B, the method further includes S401 before S311 and S312 described above. Meanwhile, the S311 may specifically include S311 b, and the S312 may specifically include S312b, where:

S401, the core network 3 determines the operator comparison result of each mobile call party according to the first operator identifier and the second operator identifier.

In the embodiment where the core network 3 includes the first core network and the second core network, taking the mobile phone 1 requesting to make a mobile call with the mobile phone 2 as an example, the first core network performs S309 above. The step S401 may specifically include: the first core network receives a second operator identifier from the second core network, and the first core network determines an operator comparison result of each party of the mobile call according to the first operator identifier and the second operator identifier.

The operator comparison result is used for representing whether the first operator and the second operator belong to preset operators or not. After acquiring the first operator identifier and the second operator identifier, the core network 3 may determine whether the first operator belongs to a preset operator according to the first operator identifier, and determine whether the second operator belongs to the preset operator according to the second operator identifier. Further, the core network 3 may generate an operator comparison result according to the above determination result. The operator comparison result may specifically be that the first operator and the second operator belong to preset operators; or the operator comparison result may be that the first operator and/or the second operator do not belong to the preset operator.

In some embodiments, the operator comparison results generated by the core network 3 are specifically denoted by different numbers; for example, when the first operator and the second operator both belong to the preset operators, an operator comparison result is generated to be 01, and when the first operator and/or the second operator do not belong to the preset operators, an operator comparison result is generated to be 00.

And S311b, the core network 3 sends the comparison result of the highest coding and decoding type and the operators of the mobile communication parties to the mobile phone 1 through the base station 4.

In the embodiment where the core network 3 includes the first core network and the second core network, taking the mobile phone 1 requesting to make a mobile call with the mobile phone 2 as an example, the first core network performs S309 above. The step S311b may specifically include: the first core network sends the comparison result of the highest codec type and the operators of the parties of the mobile phone call to the mobile phone 1 through the base station 4.

S312b. the core network 3 sends the comparison result of the highest codec type and the operators of the parties of the mobile phone call to the mobile phone 2 through the base station 5.

In the embodiment where the core network 3 includes the first core network and the second core network, taking the mobile phone 1 requesting to make a mobile call with the mobile phone 2 as an example, the first core network performs S309 above. The step S312b may specifically include: the first core network sends an operator comparison result to the second core network; the second operator sends the highest codec type and the operator comparison result of each party of the mobile phone call to the mobile phone 2 through the base station 5.

In the technical scheme provided by the embodiment of the application, the core network 3 judges whether operators used by all parties of the mobile call for establishing the mobile call are preset operators, and then the judged operator comparison results are respectively sent to all parties of the mobile call. And the mobile call parties can directly determine whether the operator information meets the condition of supporting VoLTE call according to the operator comparison result, so as to determine whether the HD call icon needs to be displayed. Therefore, the display of the HD icon by the mobile phone in the call process can be more in line with the actual situation. And displaying the HD icon on the mobile phone display screen when the current network quality is determined to meet the VoLTE call condition. The problem that the actual conversation quality can not reach the VoLTE conversation quality due to the fact that the HD icon is displayed is avoided, and poor experience is brought to a user.

S313, the mobile phone 1 receives the highest coding and decoding capability and the operator information of each mobile call party sent by the core network 3 through the base station 4.

In the embodiment of fig. 4A, the operator information received by the handset 1 includes a second operator identity of the handset 2. At this time, for the mobile phone 1, the mobile phone 1 may determine an operator used by the mobile phone 1 to establish a mobile phone call, that is, the mobile phone 1 may also obtain an operator identifier of the mobile phone 1 itself, that is, a first operator identifier.

S314, the mobile phone 2 receives the highest coding and decoding capability and the operator information of each party of the mobile call from the core network 3 through the base station 5.

In the embodiment of fig. 4A, the operator information received by the handset 2 includes a first operator identity of the handset 1. At this time, for the mobile phone 2, the mobile phone 2 may determine an operator used by the mobile phone 2 to establish a mobile phone call, that is, the mobile phone 2 may also obtain an operator identifier of the mobile phone 2 itself, that is, a second operator identifier.

It should be understood that the above-described processes of S313 and S314 may be performed simultaneously, S313 may be performed first and S314 may be performed second, or S314 may be performed first and S313 may be performed second. The present application is not limited to the order of S313 and S314.

Further, after S313 and S314, the mobile phone 1 and the mobile phone 2 respectively receive the highest codec type and the operator information, and then the mobile phone 1 and the mobile phone 2 can respectively combine the highest codec type and the operator information of each party of the mobile phone to determine whether the HD icon needs to be displayed. S315 and S316 as shown in fig. 3, wherein:

s315, the mobile phone 1 judges whether the highest coding and decoding type meets the preset coding and decoding conditions or not, and whether the operator information meets the preset operator conditions or not.

The mobile phone 1 is preset with preset coding and decoding conditions and preset operator conditions. In some embodiments, the codec condition and the preset operator condition may be preset by adding a configuration item to the mobile phone 1, and in what case the mobile phone 1 needs to display the HD call icon. An example of a configuration item provided in an embodiment of the present application is shown in table 1.

TABLE 1

S316, the mobile phone 2 judges whether the highest coding and decoding type meets the preset coding and decoding conditions or not, and whether the operator information meets the preset operator conditions or not.

It should be understood that the above processes of S315 and S316 may be performed simultaneously, S315 may be performed first and S316 may be performed second, or S316 may be performed first and S315 may be performed second. The present application is not limited to the order of S315 and S316.

The preset coding and decoding conditions and the preset operator conditions are conditions for supporting the mobile call to be VoLTE call. The preset codec conditions and the preset operator conditions may be set according to actual situations. If the highest coding and decoding type meets the preset coding and decoding conditions and the operator information meets the preset operator conditions, the network conditions of the current call are good, and VoLTE call can be supported. At this time, the mobile phone 1 may perform S317, and the mobile phone 2 may perform S318 similarly.

S317, the mobile phone 1 displays the high definition HD call identification.

In some embodiments, a plurality of preset codec types capable of satisfying the VoLTE call are defined in the preset codec condition. When the highest coding and decoding type used by the mobile call support belongs to one of the preset coding and decoding types, the highest coding and decoding type is indicated to accord with the VoLTE call condition. Illustratively, the preset operators include WB codec types; when the highest coding and decoding type is judged to be the WB coding and decoding type, the mobile phone 1 determines that the preset coding and decoding conditions are met.

In other embodiments, the minimum bandwidth satisfying the VoLTE call may be defined in the preset codec condition. When judging whether the highest coding and decoding type meets the preset coding and decoding conditions, the mobile phone 1 can judge whether the highest coding and decoding type meets the preset coding and decoding conditions by judging whether the bandwidth supported by the highest coding and decoding type is larger than the lowest bandwidth. Specifically, if the bandwidth supported by the highest codec type is greater than the lowest bandwidth, the mobile phone 1 may determine that the highest codec type meets the preset codec condition. Or, if the bandwidth supported by the highest codec type is less than or equal to the lowest bandwidth, the mobile phone 1 determines that the highest codec type does not meet the preset codec condition.

As can be seen from the above description, the network quality is different under the same condition in the networks of different operators due to the difference of the network construction capacities of the different operators. Some operators want the mobile phone to decide whether to display the HD call icon according to the network quality condition during the call. The network quality of the mobile call is judged whether to meet the condition or not, and the judgment can be performed by an operator corresponding to the network supported by the current mobile call. The operator may consider the network quality of the operator itself to be satisfactory or the operator may consider the network quality of some operators to be satisfactory.

In some embodiments, one preset operator may be defined in the preset operator condition. And judging that the operator information meets the preset operator condition when the operator information corresponding to each current mobile call party represents that the operators used by each mobile call party belong to the preset operators.

In other embodiments, a plurality of preset operators capable of satisfying the VoLTE call may be defined in the preset operator condition. When the operator information corresponding to each party of the current mobile call belongs to the preset operator, the operator information can be determined to meet the preset operator condition.

As can be seen from the above description of the embodiments, the operator information received by the mobile phone 1 or the mobile phone 2 may be the operator identifier of the other mobile phone parties, and then the mobile phone 1 or the mobile phone 2 determines the own operator identifier and compares with the other operator identifiers. Further, in this embodiment, after receiving the second operator identifier of the mobile phone 2, the mobile phone 1 may determine whether the first operator is a preset operator according to the first operator identifier, and determine whether the second operator is a preset operator according to the second operator identifier. After determining whether the first operator and the second operator belong to the preset operator, the mobile phone 1 may determine whether the operator information satisfies the preset operator condition.

In some embodiments, the mobile phone 1 determines that the operator information satisfies the preset operator condition when both the first operator and the second operator belong to the preset operator. When the first operator and/or the second operator do not belong to the preset operator, the mobile phone 1 determines that the operator information does not meet the preset operator condition.

Alternatively, the operator information received by the mobile phone 1 or the mobile phone 2 may be an operator comparison result generated by the core network 3 according to the first operator identifier and the second operator identifier. In this embodiment, the mobile phone 1 or the mobile phone 2 may directly determine whether the preset operator condition is satisfied according to the operator comparison result. In some embodiments, when the operator comparison result indicates that the first operator and the second operator both belong to the preset operator, the mobile phone 1 or the mobile phone 2 determines that the operator information meets the preset operator condition. When the comparison result of the operators represents that the first operator and/or the second operator does not belong to the preset operator, the mobile phone 1 or the mobile phone 2 determines that the operator information does not meet the preset operator condition.

The HD session identifier is used to indicate whether VoLTE sessions are currently supported. Specifically, if the mobile phone 1 determines that the VoLTE call can be supported currently according to the operator information and the highest codec type, the mobile phone 1 may display the HD call identifier on the display screen. In contrast, if the mobile phone 1 determines that the VoLTE call cannot be supported currently through the above operator information and the highest codec type, the mobile phone 1 does not display the HD call identifier on the display screen.

In some embodiments, the HD call identifier may specifically include an HD icon, an hd+ icon, or the like. For example, the handset 1 may display an HD icon on a signal bar of a display screen of the handset 1, such as the HD icon 611 of the mobile phone interface 610 shown as a in fig. 5. Alternatively, the mobile phone 1 may display an HD icon on the call interface of the mobile phone 1, such as the HD icon 621 of the mobile call interface 620 shown in b in fig. 5. In other embodiments, the handset 1 may also display an HD icon in the call record after the mobile call ends, to indicate that this mobile call is a VoLTE call.

S318, displaying the high definition HD call identification by the mobile phone 2.

In the technical scheme provided by the embodiment of the application, in the process of carrying out mobile communication, the core network 3 negotiates and determines the highest coding and decoding type which can be used in the mobile communication according to the coding and decoding capabilities of the mobile phone 1 and the mobile phone 2 and the coding and decoding capabilities of the core network 3. And the core network 3 sends the highest coding and decoding type determined by negotiation and the operator information of both mobile communication parties to the mobile phone 1 and the mobile phone 2 respectively, so that the mobile phone 1 and the mobile phone 2 can combine the highest coding and decoding type and the operator information to determine whether to display the HD communication icon. Therefore, each party of the mobile call can determine whether to display the HD call icon on the display screen of the mobile phone according to the actual network condition, and the display of the HD call icon is ensured to be in line with the actual network condition of the mobile call in the mobile call process. The problem that the electronic equipment displays the HD call icon under the condition that the actual network quality is poor and the standing VoLTE call can not be met, namely the display is inconsistent with the actual situation, so that poor call experience is brought to a user is avoided.

In the above embodiment, the core network 3 negotiates and determines the highest codec type that can be used in the mobile phone according to the codec capabilities of the mobile phone 1, the mobile phone 2 and the core network 3, and then sends the highest codec type to the mobile phone 1 and the mobile phone 2 respectively. In other embodiments, the core network 3 may also send the codec capabilities of the other parties of the mobile call and the codec capabilities of the core network 3 to each party of the mobile call separately. If the core network 3 sends the second codec capability of the handset 2 and the third codec capability of the core network 3 to the handset 1, the core network 3 sends the coding capability of the handset 1 and the third codec capability of the core network 3 to the handset 2. So that each party of the mobile call can determine the highest coding and decoding type used by the mobile call support according to the coding and decoding capabilities supported by each party of the mobile call and the core network. After determining the highest codec type, the mobile phone 1 or the mobile phone 2 may still determine whether to display the HD call icon by combining whether the highest codec type meets the preset codec condition and whether the operator information meets the preset operator condition. The display of the HD phone icon still matches the actual network situation of the mobile phone.
