The calling IMS domain 12 and the called IMS domain 14 include, for example, an S-CSCF (Serving Call Session Control Function), an I-CSCF (Interrogating CSCF, service Call Session Control Function), a P-CSCF (Proxy Call Session Control Function), and other network devices.
Fig. 2 is a schematic flow chart of some embodiments of the ringback tone playing method disclosed in the present disclosure.
As shown in fig. 2, the method of this embodiment includes:
step 21, the internet interconnection access control device receives a call request initiated by a calling terminal located in a calling IMS domain, and sends the call request to a called terminal located in a called IMS domain.
The calling request is initiated by the calling terminal and reaches the called terminal through the calling IMS domain, the I-BAC and the called IMS domain.
Step 22, the internet interconnection access control device receives a call response returned by the called terminal aiming at the call request, wherein the call response carries the called ring back tone response information.
The call response returned by the called terminal reaches the I-BAC via the called IMS domain.
Step 23, the internet interconnection access control device detects whether the called ring back tone response information conforms to the ring back tone rule of the calling IMS domain, if not, step 24 is executed, and if so, the call response can be forwarded to the calling terminal.
Step 24, the internetwork interconnection access control equipment adapts the parameters related to the ring back tone in the call response according to the ring back tone rule of the calling IMS domain.
The parameters related to the ring back tone include a backward playback identifier, and the backward playback identifier includes an Early Media (PEM) parameter and a Description parameter of a Media resource, such as an SDP (Session Description Protocol) parameter.
And step 25, the internetwork interconnection access control equipment sends the processed call response to the calling terminal, so that the calling terminal obtains the ring back tone based on the processed call response.
In the embodiment, the function of the internetwork interconnection access control equipment is enhanced, so that the internetwork interconnection access control equipment can directly detect and adapt to the parameters related to the ring back tone, and can play the ring back tone if necessary, so that a calling subscriber can hear the correct ring back tone when two subscribers in IMS domains with different ring back tone rules make calls with each other.
Fig. 3 is a flow chart of some embodiments of the ringback tone playing method of the present disclosure. In this embodiment, the calling terminal is a fixed network terminal, and the called terminal is a mobile terminal.
As shown in fig. 3, the method of this embodiment includes:
step 31, the calling terminal (fixed network terminal) initiates a call request to the called terminal (mobile terminal), and the call request reaches the calling IMS domain (fixed network IMS domain) from the calling terminal.
The call request is, for example, an Invite message.
The calling IMS domain sends a call request to the I-BAC, step 32.
In step 33, the I-BAC sends a call request to the called IMS domain (mobile network IMS domain, e.g. VoLTE network).
The called IMS domain sends a call request to the called terminal, step 34.
Step 35, the called terminal returns a call response to the called IMS domain, if the called side has no playback requirement, the call response does not carry the PEM parameter and the SDP parameter.
The call response is for example an 18-message, including a 180 message, a 183 message, etc.
The called IMS domain sends a call response to the I-BAC, step 36.
Step 37, the I-BAC detects whether the call response carries PEM parameter and SDP parameter, if not, the PEM parameter and SDP parameter are added to the call response, the PEM parameter value is configured as send-only type, the SDP parameter includes media resource address configured as internet access control device address, and then the call response is sent to the calling IMS domain.
Step 38, the calling IMS domain sends the call response to the calling terminal.
And step 39, the calling terminal receives the call response, finds that the value of the PEM parameter is configured as send-only, and performs media negotiation with the I-BAC by using the SDP parameter.
Step 310, after the media negotiation is successful, the I-BAC plays the ring back tone to the calling terminal based on the negotiated media resource. The put-back tone is passed through the calling IMS domain by the I-BAC to reach the calling terminal.
In the embodiment, the function of the internetwork interconnection access control equipment is enhanced, so that the internetwork interconnection access control equipment can directly detect and adapt to the parameters related to the ring back tone, and can play the ring back tone, so that the ring back tone can be heard by the fixed network terminal when the fixed network terminal dials the mobile network terminal, and the problem of no ring back tone in the service scene is solved.
Fig. 4 is a flow chart of some embodiments of the ringback tone playing method of the present disclosure. In this embodiment, the calling terminal is a mobile terminal, and the called terminal is a fixed network terminal.
As shown in fig. 4, the method of this embodiment includes:
step 41, the calling terminal (mobile terminal) initiates a call request to the called terminal (fixed network terminal), and the call request reaches the calling IMS domain (mobile network IMS domain, such as VoLTE network) from the calling terminal.
The call request is, for example, an Invite message.
The calling IMS domain sends a call request to the I-BAC, step 42.
Step 43, the I-BAC sends the call request to the called IMS domain (fixed network IMS domain).
The called IMS domain sends a call request to the called terminal, step 44.
And step 45, the called terminal returns a call response to the called IMS domain, if the called terminal has a playback requirement, the call response carries the SDP parameter, but possibly does not carry the PEM parameter or the value of the PEM parameter is not send-only.
The call response is for example an 18-message, including a 180 message, a 183 message, etc.
The called IMS domain sends a call response to the I-BAC, step 46.
In step 47, if the I-BAC finds that the called terminal has a playback requirement but does not carry the PEM parameter or carries the PEM parameter not being send-only, the I-BAC needs to add the PEM parameter to the call response (if the PEM parameter does not exist), adapt the PEM parameter to send-only (send type), and then send the call response to the calling IMS domain.
Step 48, the calling IMS domain sends the call response to the calling terminal.
And step 49, the calling terminal receives the call response, finds that the value of the PEM parameter is configured as send-only, and performs media negotiation with the called IMS domain device by using the SDP parameter.
Step 410, after the media negotiation is successful, the called IMS domain device plays the ring back tone to the calling terminal based on the negotiated media resource. The ring back tone is put through the calling IMS domain by the called IMS domain equipment to reach the calling terminal.
In the embodiment, the function of the internetwork interconnection access control equipment is enhanced, so that the internetwork interconnection access control equipment can directly detect and adapt to the parameters related to the ring back tone, when the mobile network terminal dials the fixed network terminal, and the mobile network terminal can hear the correct ring back tone when the fixed network terminal has a sound reproduction requirement, and the problem that the calling party can not hear the ring back tone provided by the called side in the service scene is solved.
