Detailed ways

In order to understand the characteristics and technical content of the present invention in more detail, the implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

Embodiment one

An embodiment of the present invention provides a method for transmitting an additional service. FIG. 1 is a schematic flow diagram of a method for transmitting additional services according to Embodiment 1 of the present invention; as shown in FIG. 1 , the method includes:

Step 101: When receiving an additional service trigger request, acquire calling party information based on the trigger request.

The method for transmitting an additional service described in this embodiment is applied to a device, and the device may be an additional service server.

Here, the additional service is a service provided by a communication operator, and the communication operator may be a mobile operator, a China Unicom operator, a telecom operator, and the like.

Optionally, the additional service is a service set by the called party to provide the calling party while the calling party is waiting for the called party to connect when the calling party sends a call request to the called party. .

Here, the call request may be a phone call request, or a call request sent by the calling party to the called party through a third-party application.

For example, the additional service may be a ring back tone service, which is a service in which the called user sets ring-back tones with special sound effects (music, songs, story lines, character dialogues) for other calling users who call their own mobile phones . After the called user activates this service, when the calling user dials the user's mobile phone and waits to be connected, what he hears is no longer the ringback tone of "beep...beep..." A piece of multimedia content such as video or music or greetings to replace the normal ring back tone.

Optionally, the trigger request is sent by the core network to the additional service server.

In a specific implementation manner, the additional service server receives an additional service trigger request sent by the core network; wherein, the additional service trigger request is when the core network receives a call request from the calling party to the called party, according to the called It is sent by the party with additional business signing information.

Here, the calling party information includes at least the calling party user number, or the calling party terminal identification number and the like.

Step 102: Determine whether the calling party has access to the first network, and when it is determined that the calling party has access to the first network, establish a first communication link with the calling party based on the first network, and establish a first communication link based on the first communication The link transmits a first type of additional service among the additional services to the calling party.

Here, the first network may be a wireless local area network, such as a WI-FI network. Wherein, the WI-FI is an abbreviation of Wireless-Fidelity.

Here, the first type of additional service may be a video type of additional service. For example, when the additional service is a CRBT service, the first type of additional service is a video CRBT, and when the calling party receives a video CRBT, the required traffic is relatively large.

In one embodiment, before step 101, the method further includes:

receiving an additional service push registration request sent by the calling party; the registration request is used to request the additional service server to activate the function of transmitting the additional service through the first network for the calling party;

Generate additional service push registration information matching the calling party based on the registration request, and send a registration success response to the calling party.

Here, the additional service pushes registration information, including but not limited to:

Calling party user number, calling party wireless network IP address, gateway address (if it exists), port number, current network speed of the first network, and whether to select the first type of additional service push when not connected to the first network .

Here, the additional service pushing registration information may be stored in the additional service server.

In this way, when the additional service server receives the additional service trigger request, it can quickly query the additional service push registration information registered by the calling party based on the obtained calling party information, so as to determine whether the calling party is connected to the first network Provide effective support.

In an optional implementation manner, the judging whether the calling party accesses the first network includes:

Detecting whether there is a first heartbeat message corresponding to the calling party within a preset time; wherein, the first heartbeat message is sent by the calling party through the first network periodically after successfully registering with the additional service server a message sent to the additional service server;

If there is a first heartbeat message corresponding to the calling party, then determining that the calling party is connected to the first network;

If there is no first heartbeat message corresponding to the calling party, it is determined that the calling party is not connected to the first network.

In this embodiment, the preset time may be preconfigured according to actual network conditions or in combination with experience.

In this way, after successfully registering with the additional service server, the calling party regularly sends the first heartbeat message to the additional service server through the first network; in this way, the additional service server can judge whether the calling party receives the first heartbeat message. Whether to access the first network.

In another optional implementation manner, the judging whether the calling party accesses the first network includes:

Obtaining the additional service push registration information of the calling party;

Sending a first network connection status detection request to the calling party based on the additional service push registration information;

Determine whether the calling party is connected to the first network according to the first network connection status detection response message returned by the calling party.

Wherein, the first network connection state detection response message may include but not limited to the following information: the calling party user number, and the current network rate of the first network.

In this way, when the calling party initiates a call to the called party, the additional service server directly sends the first network connection status detection request to the calling party according to the previous registration information of the calling party’s additional service, and judges according to the information returned by the calling party Whether the calling party is currently connected to the first network.

Further, the method also includes:

Step 103: When it is determined that the calling party is not connected to the first network, establish a second communication link with the calling party based on the calling party's current calling network, and transmit the additional communication link to the calling party based on the second communication link. The second type of additional business in business.

Wherein, the flow required by the calling party to receive the second type of additional service is less than or equal to the flow required to receive the first type of additional service.

Here, the second type of additional service may be an audio type of additional service. For example, when the additional service is a CRBT service, the second type of additional service is an audio CRBT, and the caller needs less traffic to receive an audio CRBT.

It should be noted that, generally, the flow required for receiving the second type of additional service is smaller than the flow required for receiving the first type of additional service. However, under special circumstances, if the obtained additional service push registration information of the calling party includes that the calling party still chooses to push the first type of additional service in the additional service when the calling party is not connected to the first network, then in step 103, the The above-mentioned second type of additional service is the first type of additional service.

In this way, in general, when the calling party is not connected to the first network, the second type of additional service is transmitted to the calling party through the second communication link; In the state of the first network, the first type of additional service is still pushed, then, in the state that the calling party is not connected to the first network, the first type of additional service is transmitted to the calling party through the second communication link. In this way, while saving traffic for the calling party as much as possible, the calling party's diversified selection service requirements for additional services can be met, and the flexibility for the calling party to choose to receive the first type of additional services is also improved.

By adopting the technical scheme of the embodiment of the present invention, when the calling party is in the state of accessing the first network, the first type of additional service sent by the additional service server is received through the first network that the calling party has accessed, which ensures that the calling party The calling party can receive the first type of additional service, which solves the problem that some calling parties cannot enjoy the first type of additional service because they do not support the mobile data network used to transmit the first type of additional service; at the same time, because The calling party does not need to receive the first type of additional service through the mobile data network used by the called party, and can also save the traffic generated by receiving the first type of additional service through the mobile data network. In addition, when the calling party is in the state of accessing the first network, it can choose to receive the first type of additional service through the first network according to the current network environment, and the calling party prefers the first network that has been accessed to receive the additional service The first type of additional service sent by the server improves the flexibility of choosing to receive the first type of additional service network. Furthermore, compared to some additional service implementation schemes based on the calling terminal directly triggering the additional service server, and for this type of additional service implementation scheme, hackers can easily attack the additional service server through the terminal, causing service paralysis; however, The technical solution described in this embodiment uses the core network to complete the triggering of the additional service server, which improves the safety factor and avoids the hidden danger of false attacks.

In the following, the first type of additional service is a video ring back tone, the second type of additional service is an audio ring back tone, the additional service server is a ring back tone platform, and the first network is a WI-FI network as an example.

The CRBT platform receives the CRBT service trigger request sent by the core network; the CRBT platform obtains the calling party information based on the trigger request when receiving the additional service trigger request; judges whether the calling party accesses the WI-FI network, and determines whether the calling party When the calling party accesses the WI-FI network, a WI-FI network communication link is established with the calling party based on the WI-FI network, and a video ring tone is transmitted to the calling party based on the WI-FI network communication link. In this way, when the calling party is in the state of accessing the WI-FI network, the video CRBT sent by the CRBT platform is received through the WI-FI network that the calling party has accessed, which ensures that the calling party can receive the video CRBT. Solve the problem that some calling parties cannot enjoy the video ring back ring service because they do not support the mobile data network used to transmit the video ring back ring; at the same time, because the calling party does not need to receive the video The CRBT can also save the traffic generated by receiving the video CRBT through the mobile data network.

Embodiment two

Step 202: Determine whether the calling party is connected to the first network, if the calling party is connected to the first network, perform step 203; if the calling party is not connected to the first network, perform step 204;

For example, the first network is a WI-FI network.

Here, the manner of judging whether the calling party accesses the first network includes:

It is determined by whether the first heartbeat information regularly sent by the calling party is received, or

Sending a first network connection state detection request directly to the calling party, and judging whether the calling party is currently in the first network connection state according to the information returned by the calling party.

Step 203: Obtain the network rate of the first network, and then perform step 205;

Here, the ways to obtain the network rate of the first network include:

Obtained from the first heartbeat information regularly sent by the calling party, or

The first network speed detection request is directly sent to the calling party, and obtained from the own detection data returned by the calling party.

Step 204: Obtain the network rate of the current calling network, and then perform step 208;

Here, the way to obtain the network rate of the current calling network includes:

Obtained from the second heartbeat information about the current call network sent regularly by the calling party, or

Directly send the current call network speed detection request to the calling party, and obtain it from the own detection data returned by the calling party.

Step 205: Establish a first communication link with the calling party based on the first network, and then perform step 206;

Step 206: Combining the network rate of the first network, and/or the additional service push registration information of the calling party, and/or the additional service subscription information of the called party, from the available Select the first type of additional service to select the first type of additional service to be transmitted, and then perform step 207;

Optionally, selecting the first type of additional service to be transmitted from the optional first type of additional service among the additional services includes:

Selecting the first type of additional service to be transmitted from the optional first type of additional service among the additional services in combination with the network rate of the first network; or

In this way, higher quality additional service content can be selected for the calling party according to the different network environments and network speeds of the calling party.

In this way, the additional service server selects the best quality additional service content currently available to the calling party according to the current network conditions and network speed of the calling party and the additional service transmission requirements set by the calling party in advance.

Specifically, the quality of the supplementary service content can be divided into high-definition first-class supplementary services, standard-definition first-class supplementary services, smooth first-class supplementary services, high-definition second-class supplementary services, and standard-definition second-class supplementary services. business.

Here, the order of quality attributes is: high definition ≥ standard definition ≥ smooth.

Taking the additional service as the CRBT service as an example, the quality of the CRBT service can be divided into high-definition video CRBT, standard-definition video CRBT, smooth video CRBT, high-definition audio CRBT, and standard-definition audio CRBT.

In a specific implementation manner, each additional service content is attached with a quality attribute label or a quality attribute identifier for characterizing the quality of the additional service content.

In this way, after the additional service server determines the category of the additional service content to be transmitted, it can determine the quality attribute suitable for the network rate according to the network rate of the current network where it resides.

For example, the additional service server determines to transmit the first type of additional service to the calling party through the first network, and judges that the current network rate of the first network meets the requirements of the high-definition quality attribute, and then selects the first service of the high-definition quality attribute for the calling party. Category Additional Services.

After the called party specifies the set of additional service content to be played, when the additional service server plays the additional service content to the calling party, it needs to select the highest value acceptable to the calling party from the set of additional service content specified by the called party. Quality additional business content. When there are multiple playable additional service contents of the same quality, one may be randomly selected from the multiple playable additional service contents of the same quality as the additional service content to be played.

On the other hand, the calling party can set whether the additional service server will preferentially push the first type of additional service to the calling party when it is not in the first network. That is to say, if the calling party is set to give priority to playing the first type of additional service even if it is not the first network, no matter whether the calling party is currently connected to the first network or not, the additional service server will, according to the current network speed of the calling party, It is possible to push the highest-quality first-class additional service to the calling party. Only when the network speed does not meet the minimum rate of playing the first-class additional service, will the calling party choose to play the highest-quality second-class service acceptable to the calling party. additional business. If the user sets to only play the first type of additional service under the first network, when the CRBT platform judges that the calling party is under the first network, according to the network speed of the calling party, it will give priority to sending the best quality service to the calling party. The first type of additional service; when it is judged that the calling user is not in the first network, the additional service server pushes the best quality second type of additional service for the user according to the current network speed of the calling party.

In this embodiment, the first type of additional service can be understood as a video additional service, such as a video ring back tone; the second type of additional service can be understood as an audio additional service, such as an audio ring back tone.

By adopting the technical solution described in this embodiment, the calling party can transmit the first type of additional service through the first network, which saves the calling party the high traffic fee generated by the first type of additional service, and solves the problem of using traffic billing. Finally, because the first type of additional service needs to generate a large amount of traffic, it will bring high traffic charges to the calling party and affect the promotion of additional services. On the other hand, the technical solution described in this embodiment can select higher-quality additional services for the calling party according to the different network environments and network speeds of the calling party, so as to ensure that 100% of the additional services are reachable, that is, Regardless of whether the calling party supports the first network to play the first type of additional service, the additional service server first determines the current network status of the calling party and its network speed, and then transmits the information for the calling party to the current network and network speed. In this way, at least the second type of additional service supported by each calling terminal can be guaranteed to be transmitted to the calling party. On the other hand, compared to the transmission method in the prior art where additional services are randomly selected for transmission from several additional service contents set by the called party, due to random selection, no matter how good the current network environment is bad, the selected additional service content must adapt to the playing conditions of the worst network; and adopt the technical solution described in this embodiment, can select higher-quality additional service content for the calling party according to the quality of the calling party’s network conditions. play. In the last aspect, the triggering of the additional service server is completed by the core network, not directly by the calling party, and there is no hidden danger of false attacks.

In the following, continue to take the first type of additional service as video CRBT, the second type of additional service as audio CRBT, the additional service server as CRBT platform, and the first network as WI-FI network as examples.

The CRBT platform receives the CRBT service trigger request sent by the core network; obtains the current resident network of the calling terminal based on the CRBT service trigger request; obtains the network rate of the current resident network of the calling terminal; and the network rate of the currently resident network, select the network for playing the CRBT and the CRBT content to be played, and play the CRBT content to the calling terminal through the network for playing the CRBT. In this way, according to the different network environments and network speed conditions of the calling party, a higher-quality ring tone service can be selected for the calling party.
