Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a method and device for communication negotiation, an electronic device, and a computer-readable storage medium. Background Art

[0002] The color ring back tone service has always been one of the main value-added services of operators. In the actual communication process, in order to distinguish the call data and the color ring back tone data between the caller and the called, the call data is defined as regular media, and the color ring back tone data is defined as early media.

[0003] There are multiple modes of early media, including local voice playback mode and network voice playback mode. The network voice playback mode can be further divided into two-way network voice playback mode and one-way network voice playback mode. The early media modes adopted by different operators may be different. If the early media modes adopted by the calling and called operators are incompatible, the negotiation between the calling and called for early media will fail, resulting in the problem that the calling and called cannot communicate normally. Summary of the invention

[0004] The present disclosure provides a communication negotiation method and device, an electronic device, and a computer-readable storage medium to address deficiencies in related technologies.

[0005] According to a first aspect of an embodiment of the present disclosure, a communication negotiation method is provided, the method being applied to a calling device and comprising:

[0006] Sending an invitation message to establish a call to the called device, and receiving a response message returned by the called device;

[0007] In response to the called device requesting network announcement, establishing a link for transmitting network announcement data with the calling-side server according to the link message in the response message;

[0008] In response to the established link not meeting the link requirement corresponding to the target early media field in the response message, determining whether the operator of the calling device belongs to a preset operator;

[0009] In response to the operator of the calling device belonging to the preset operator, it is determined that the early media negotiation with the called device is successful, and after performing network playback, the call with the called device is continued.

[0010] According to a second aspect of an embodiment of the present disclosure, a communication negotiation device is provided. The device uses a calling device, including a message transceiver module, a link establishment module, an operator determination module, and a call execution module:

[0011] The message transceiver module is used to send an invitation message for establishing a call to the called device and receive a response message returned by the called device;

[0012] The link establishment module is used to establish a link for transmitting network playback data with the calling side server according to the link message in the response message in response to the called device requesting network playback;

[0013] The operator determination module is used to determine whether the operator of the calling device belongs to a preset operator in response to the established link not meeting the link requirement corresponding to the target early media field in the response message;

[0014] The call execution module is used for determining that the early media negotiation with the called device is successful in response to the operator of the calling device belonging to the preset operator, and continuing the call with the called device after executing network playback.

[0015] According to a third aspect of an embodiment of the present disclosure, an electronic device is provided, comprising a processor and a memory for storing instructions executable by the processor;

[0016] The processor implements the steps in the method described in the first aspect above by running the executable instructions.

[0017] According to a fourth aspect of an embodiment of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored, and when the program is executed by a processor, the steps in the method described in the first aspect are implemented.

[0018] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0019] In response to the incompatibility of the early media modes adopted by the operators of the calling and called parties, when the calling party detects that the link it has established cannot meet the link requirements corresponding to the target early media field in the called party's response message, it detects whether the operator of the calling device is the preset operator. If so, it determines that the two have successfully negotiated for early media. After the calling party executes network playback, it continues the call process with the called party without canceling the call, thereby ensuring normal communication between the two.

[0020] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] In the field of communications, the party that actively initiates a call is the calling party, and the party that passively receives the call is the called party. In the scenario of a cross-operator call, the calling device used by the calling party will communicate with the called device through the calling side server, which is provided by the operator of the calling device; while the called device used by the called party will communicate with the calling device through the called side server, which is provided by the operator of the called device. It can be understood that in addition to the calling side server and the called side server, the interactive data between the calling device and the called device can also pass through network devices such as switches and gateways, which will not be repeated here.

[0029] Before the actual call, the calling device and the called device can exchange multimedia data such as color ringback tone and color vibration, which is different from the actual call data of both parties. This data transmission before the actual call is defined as early media.

[0030] Early media modes include local playback mode and network playback mode. In the local playback mode, the call device can play the audio cached locally without establishing a link with the server on its side; while in the network playback mode, the call device will establish a link with the server on its side, thereby sending the other party the early media data specified by itself or receiving the early media data specified by the other party, that is, the call device will play the audio conveyed by the server on its side.

[0031] The network playback mode further includes a two-way network playback mode and a one-way network playback mode. The difference between the two is that when the early media mode supported by the operator of the call device is a two-way network playback mode, the call device can simultaneously establish an uplink and a downlink with the server on its side, so that it can send the early media data specified by itself to the other party and receive the early media data specified by itself sent by the other party; when the early media mode supported by the operator of the call device is a one-way network playback mode, the call device can only establish a downlink with the server on its side but not an uplink with the server on its side, so that it can only receive the early media data specified by itself sent by the other party but not send the early media data specified by itself to the other party.

[0032] Different operators use different early media modes. In the case of cross-operator calls, it often happens that the operators of the calling and called parties use incompatible early media modes, resulting in the failure of early media negotiation between the calling and called parties and the inability to continue the call.

[0033] For example, when the early media mode adopted by the operator of the calling device is a one-way network playback mode, if the early media mode adopted by the operator of the called device is a two-way network playback mode, based on the protocol specification of 3GPP (3rd Generation Partnership Project), the calling device will determine that the early media negotiation with the called device has failed after detecting that it cannot establish the uplink required by the two-way network playback mode with the calling side server, and actively cancel the call with the called device. However, in fact, the lack of an uplink between the calling device and the calling side server does not affect the transmission of early media data. The downlink between the calling device and the calling side server can already transmit the audio data such as the ringback tone of the called device to the calling device, so there is no need for the calling device to cancel the call with the called device.

[0034] In view of this, this specification provides a communication negotiation method, which avoids the above-mentioned problem of being unable to make calls due to early media negotiation failure by detecting the operator of the calling device without requiring the supplier server to change the configuration and maintaining the original protocol specifications.

[0035] Figure 1 The present invention is a flow chart of a communication negotiation method according to an exemplary embodiment.

[0036] The communication negotiation method is applied to an electronic device, and the electronic device is a calling device during the communication negotiation process. The communication negotiation method includes the following steps:

[0037] Step 102: The calling device sends an invitation message to the called device to establish a call, and receives a response message returned by the called device.

[0038] In the process of establishing a call between the calling device and the called device, first, the calling device will actively send an invitation message to the called device to establish the call, and the invitation message can be forwarded by the calling side server, the switch, gateway and other network devices between the calling party and the called party, and the called side server, and finally reach the called device. It can be understood that in some implementations, before sending the invitation message, the calling device needs to query the communication address or number of the called device from the calling side server, switch, roaming server, etc. The specific content can be referred to the relevant technology, which will not be repeated here.

[0039] After receiving the invitation message from the calling device, the called device will return a response message to the calling device according to its own status. Usually, the response message is a signaling message for negotiating early media, and there is a target early media field in its message header field, which can represent the early media mode adopted by the operator of the called device. After receiving the response message, the calling device will extract the target early media field therein, and detect whether the target early media field corresponds to the network playback mode to determine whether the called device requires network playback.

[0040] For example, when the field value of the target early media field P-Early-Media (abbreviated as PEM field) in the response message header field is sendrecv or sendonly, it indicates that the early media mode adopted by the operator of the called device is the network playback mode, wherein the PEM field value is sendrecv corresponding to the two-way network playback mode, and the PEM field value is sendonly corresponding to the one-way network playback mode. If the calling device extracts the field value of the P-Early-Media field in the response message header field as sendrecv or sendonly, it can be determined that the called device requires the calling device to perform network playback.

[0041] Step 104: In response to the called device requesting network announcement, the calling device establishes a link for transmitting network announcement data with the calling-side server according to the link information in the response message.

[0042] In the case where the called device requires network playback, the response message returned by the called device to the calling device carries a link message, wherein the link message is used to instruct the calling device how to establish a link with the calling-side server to transmit network playback data, including link requirements such as traffic limit, etc. The link message includes an uplink message and / or a downlink message, and the specific number and type of the link messages included correspond to the early media mode adopted by the operator of the called device.

[0043] After determining that the called device requires network playback, the calling device will establish a link with the calling side server according to the link message in the response message. Specifically, the calling device can establish a corresponding uplink with the calling side server according to the uplink message in the response message, and establish a corresponding downlink with the calling side server according to the downlink message in the response message.

[0044] Step 106: In response to the established link not meeting the link requirement corresponding to the target early media field in the response message, the calling device determines whether its operator is a preset operator.

[0045] After determining that the uplink and / or downlink requested to be established with the calling side server is successfully established, the calling device will determine whether the successfully established link meets the link requirement corresponding to the target early media field in the response message.

[0046] Target Early Media Field in Response Message Link requirements PEM=sendrecv Both uplink and downlink are established successfully PEM=sendonly Downlink established successfully

[0047] Table 1

[0048] As shown in Table 1, when the target early media field in the response message is sendrecv, the operator of the called device adopts a two-way network playback mode, and its corresponding link requirement is: both the uplink and the downlink are successfully established; when the target early media field in the response message is sendonly, the operator of the called device adopts a one-way network playback mode, and its corresponding link requirement is: the downlink is successfully established. According to Table 1, the calling device can detect whether the link established between it and the calling side server meets the link requirement corresponding to the target early media field in the response message.

[0049] Taking the field value of the target early media field P-Early-Media in the response message as sendrecv as an example, the corresponding link requirement is: both the uplink and the downlink are successfully established. When the calling device detects that the successfully established links include both the uplink and the downlink, it means that both use the two-way network playback mode and can perform network playback normally.

[0050] When the calling device detects that the established link does not meet the link requirement corresponding to the target early media field, in order to avoid the problem of the calling party canceling the call due to incompatibility of the early media modes of the calling party and the called party as mentioned above, the calling device will detect whether its operator is the preset operator.

[0051] When the link requirement corresponding to the target early media field in the response message requires the establishment of an uplink, and the calling device detects that the successfully established link does not include an uplink, the calling device can detect whether its operator belongs to the preset operator. The early media mode used by several operators preset on the calling device is a one-way network playback mode. The specific preset operator and the specific number of operators can be configured by the technical staff according to the business cooperation and application scenarios.

[0052] Step 108: In response to the operator of the calling device belonging to the preset operator, it is determined that the early media negotiation between the calling device and the called device is successful, and the call between the calling device and the called device continues.

[0053] After determining that the operator of the calling device belongs to the preset operator, the calling device can determine that it has successfully negotiated the early media with the called device and perform network playback normally, including feeding back the early media negotiation success to the called device, receiving and playing the subsequent audio data, etc.; after the network playback ends, the calling device can continue the call with the called device. For the specific process of the calling device continuing to talk with the called device after the network playback, please refer to the relevant technology, which will not be repeated here.

[0054] After determining that the operator of the calling device is not a preset operator, the calling device may determine that the early media negotiation between it and the called device has failed, and cancel the call with the called device.

[0055] Taking the case where the operator of the called device adopts the two-way network playback mode as an example, the response message will carry an uplink message and a downlink message so that the calling device and the calling side server can establish the corresponding uplink and downlink. However, if the early media mode adopted by the operator of the calling device is incompatible with the one-way network playback mode, based on the 3GPP protocol specification, the calling side server will delete the uplink message in the response message when forwarding the response message to the calling device. The calling device can only establish a downlink with the calling side server, and the successfully established link cannot include the uplink required by the target early media field sendrecv. However, by setting the operator of the calling device to the preset operator, after detecting that the successfully established link does not meet the link requirements, the calling device can still determine that the early media negotiation is successful through operator identification, perform network playback normally, and continue the call with the called device.

[0056] In summary, using Figure 1 The communication negotiation method proposed in the illustrated embodiment addresses the problem of incompatibility of early media modes adopted by the operators of the calling party and the called party. When the calling party detects that the link it has successfully established cannot meet the link requirements corresponding to the target early media field in the called party's response message, it detects whether the operator of the calling device is the preset operator. If so, it determines that the two have successfully negotiated on early media. After the calling party executes network playback, it continues to execute the call process with the called party without canceling the call, thereby ensuring normal communication between the two.

[0057] There are multiple selectable implementations for determining whether the operator of the calling device is a preset operator in step 106 .

[0058] In an optional implementation, several operator identifiers may be preset on the calling device, and by matching the operator identifier of the calling device with the preset operator identifier, it is determined whether the negotiation between the calling device and the called device for the early media is successful or not; including:

[0059] The operator identifier of the calling device is obtained, and the calling device detects whether the operator identifier matches the preset operator identifier.

[0060] Specifically, the calling device may obtain its own MCC (Mobile Country Code) and MNC (Mobile Network Code), and match them with the MCC and MNC of a preset operator to determine a specific operator in combination with the MCC and MNC.

[0061] In response to the operator identifier of the calling device matching any preset operator identifier, it is determined that the operator of the calling device belongs to the preset operator, the calling device determines that the early media negotiation with the called device is successful, and continues the call with the called device after executing network playback; in response to the operator identifier of the calling device not matching all preset operator identifiers, it is determined that the operator of the calling device does not belong to the preset operator, the calling device determines that the early media negotiation with the called device has failed, and cancels the call with the called device.

[0062] This implementation method can improve the accuracy of the calling device confirming whether its operator is the preset operator.

[0063] Figure 2 The present invention is a flow chart of another communication negotiation method according to an exemplary embodiment, in which a downlink actually used to transmit the network playback data of the called party is confirmed to further ensure a smooth call between the calling device and the called device. The communication negotiation method includes the following steps:

[0064] Step 202: The calling device sends an invitation message to the called device to establish a call, and receives a response message returned by the called device.

[0065] Step 204: In response to the called device requesting network announcement, the calling device establishes a link for transmitting network announcement data with the calling-side server according to the link information in the response message.

[0066] For the specific implementation of steps 202 to 204, please refer to the above Figure 1 Steps 102 to 104 of the illustrated embodiment will not be described in detail here.

[0067] Step 206: In response to the established link not meeting the link requirement corresponding to the target early media field, the calling device determines whether the link message of the response message includes a downlink message.

[0068] Step 208: In response to the link message in the response message not including a downlink message, the calling device determines that the early media negotiation between it and the called device has failed, and cancels the call with the called device.

[0069] When a link is established with the calling side server based on the link message in the response message and both are successfully established, it is detected that the successfully established link does not meet the link requirement corresponding to the target early media field. The calling device further detects whether the link message includes a downlink message to determine whether the downlink actually used to transmit the called party's audio data is successfully established.

[0070] If the link message does not include a downlink message, it means that the downlink between the calling device and the calling side server is not established successfully, and the early media data cannot be transmitted. The calling device determines that the early media negotiation fails and cancels the call to the called device.

[0071] Step 210: In response to the link message of the response message including a downlink message, the calling device determines whether its operator is a preset operator.

[0072] Step 212: In response to the operator of the calling device being a preset operator, the calling device determines that the early media negotiation with the called device is successful, and continues the call with the called device after performing network playback.

[0073] For the specific implementation of steps 210 to 212, please refer to the above Figure 1 Steps 106 to 108 of the illustrated embodiment will not be described in detail here.

[0074] Figure 2 The illustrated embodiment confirms whether the downlink actually used to transmit the network announcement data to the calling device is successfully established, which can further ensure that the call between the calling device and the called device proceeds smoothly.

[0075] Figure 3 is a flow chart of another communication negotiation method according to an exemplary embodiment, further including the case of executing local playback and canceling the call due to rejection by the called device. The communication negotiation method includes:

[0076] Step 302: The calling device sends an invitation message to the called device to establish a call, and receives a response message returned by the called device.

[0077] Step 304: The calling device determines whether the response message is a response message for agreeing to establish a call.

[0078] Step 306: In response to the response message not being a response message for agreeing to establish the call, the calling device cancels the call with the called device.

[0079] In some specific scenarios, the response message returned by the called device is not a signaling message for negotiating early media, but other response messages indicating that the call is not agreed to be established, including signaling messages indicating that the other party refuses the call or is continuously busy, etc. Therefore, when the calling device receives the response message, it can first detect the nature of the message. After detecting that the response message is not a message agreeing to establish the call, it can cancel the call to the called device without negotiating the early media.

[0080] Step 308: In response to the response message being a response message for agreeing to establish a call, the calling device determines whether the called device requires the network to play the audio according to the target early media field in the response message.

[0081] Refer to the above Figure 1 In step 102 of the illustrated embodiment, the calling device extracts the target early media field in the response message returned by the called device after receiving the response message, and determines whether the called device requires network playback according to the target early media field in the response message.

[0082] Step 310: In response to the called device not requiring network playback, the calling device performs local playback.

[0083] When the calling device determines that the target early media field in the response message does not correspond to the network playback mode, that is, the called device does not require network playback, which means that the called device has not activated the color ring back tone service, the calling device can directly read the local audio cached in the calling device to perform local playback without establishing a link with the calling side server. After performing local playback, the calling device can continue the call with the called device.

[0084] Step 312: In response to the called device requesting network announcement, the calling device establishes a link for transmitting network announcement data with the calling-side server according to the link message in the response message.

[0085] Step 314: In response to the established link not meeting the link requirement corresponding to the target early media field, the calling device determines whether its operator is a preset operator.

[0086] Step 316: In response to the operator of the calling device being a preset operator, the calling device determines that the early media negotiation between the calling device and the called device is successful, and continues the call with the called device.

[0087] For the specific implementation of steps 312 to 316, please refer to the above Figure 1 Steps 104 to 108 of the illustrated embodiment will not be described in detail here.

[0088] Figure 3 The illustrated embodiment further includes processing for situations such as local playback and the called party rejecting the call.

[0089] In order to enable those skilled in the art to better understand the communication negotiation method proposed in the present disclosure, further detailed description is given below. The embodiments described subsequently are only part of the embodiments of the present disclosure, rather than all the embodiments.

[0090] In the cross-operator call scenario, the early media mode adopted by the operator of the calling device is the one-way network playback mode, and the early media mode adopted by the operator of the called device is the two-way network playback mode. Both support network playback.

[0091] At a certain moment, the calling device sends an invitation message to the called device to establish a call, which is forwarded to the called device by the calling side server, switch, called side server, etc.

[0092] The called device has activated the color ring back tone service, and it returns a signaling message for negotiating early media to the calling device as a response message, wherein the response message includes an uplink message and a downlink message.

[0093] The calling-side server deletes the uplink message in the response message and retains the downlink message in the response message based on the 3GPP protocol specification and the one-way network playback mode adopted by the operator of the calling device.

[0094] After receiving the response message from the called device, the calling device confirms that the response message is a message for agreeing to establish a call, obtains the target early media field PEM=sendrecv in the response message, and confirms that the called device requires the network to play the voice.

[0095] The calling device successfully establishes a downlink with the calling side server according to the downlink message in the response message, and detects whether the successfully established downlink meets the link requirement corresponding to the target early media field PEM=sendrecv: both the uplink and the downlink are successfully established.

[0096] The successfully established downlink does not meet the link requirement corresponding to the target early media field PEM=sendrecv, including the successful establishment of an uplink. The calling device detects whether the link message of the response message includes a downlink message.

[0097] After confirming that the response message includes a downlink message, the calling device detects whether its MCC and MNC belong to the preset MCC and MNC. After confirming that the MCC and MNC of the calling device belong to the preset MCC and MNC, it feeds back to the called device that the early media negotiation is successful, waits for the audio data of the called party, and continues the call with the called device after the network playback ends.

[0098] Corresponding to the aforementioned communication negotiation method embodiment, the present disclosure also provides a communication negotiation device embodiment.

[0110] In response to the operator of the calling device not belonging to the preset operator, it is determined that the early media negotiation with the called device has failed, and the call with the called device is cancelled.

[0111] Optionally, the calling device is preset with several operator identifiers; when determining whether the operator of the calling device belongs to the preset operator, the operator determination module 430 is specifically used to:

[0112] Obtaining the operator identifier of the calling device, and determining whether the obtained operator identifier matches the preset operator identifier;

[0113] In response to the acquired operator identifier matching any of the preset operator identifiers, determining that the operator of the calling device belongs to the preset operator;
