Specific implementation mode

In order to more fully hereinafter understand the features of the present invention and technology contents, below in conjunction with the accompanying drawings to the reality of the present invention It is now described in detail, appended attached drawing purposes of discussion only for reference, is not used for limiting the present invention.

Embodiment one

An embodiment of the present invention provides a kind of transmission methods of supplementary service.Fig. 1 is the additional industry of the embodiment of the present invention one The flow diagram of the transmission method of business；As shown in Figure 1, the method includes：

Step 101：When receiving supplementary service trigger request, calling party information is obtained based on the trigger request.

The transmission method of supplementary service described in the present embodiment is applied in an equipment, and the equipment can be that supplementary service takes Business device.

Here, the supplementary service is the service provided by communicating operator, and the communication operator can be mobile fortune Seek quotient, unicom operator, telecom operators etc..

Optionally, the supplementary service is calling party when sending call request to callee, is waited in calling party called It is the service that calling party provides by callee's setting during side connects.

Here, the call request can be phone call request, can also be calling party by third-party application to quilt The call request that the side of crying is sent.

For example, the supplementary service can be Ring Back Tone service, it be one by called subscriber be call oneself mobile phone Other calling subscribes set special sound effect (music, song, plot, human dialog) ring-back tone business.It is called to use After this business is opened at family, for calling subscribe when dialing user mobile phone waiting connection, what is heard is no longer just " beep ... The ring-back tone of beep ... ", but one section of video or the multimedia forms such as music or greeting content are provided for calling subscribe to replace For common ring-back tone.

Optionally, the trigger request is sent from core net to supplementary service server.

In a specific embodiment, supplementary service server receives the supplementary service trigger request that core net is sent；Its In, when the supplementary service trigger request is the call request that the core net receives calling party to callee, according to called Square supplementary service signing information and send out.

Here, the calling party information includes at least calling part user number or calling party end identification number etc..

Step 102：Judge whether calling party accesses first network, and when determining that calling party accesses first network, is based on The first network establishes the first communication link with calling party, described additional to calling party's transmission based on first communication link First kind supplementary service in business.

Here, the first network can be WLAN, such as WI-FI network.Wherein, the WI-FI is The abbreviation of Wireless-Fidelity.

Here, the first kind supplementary service can be video class supplementary service.For example, when the supplementary service is CRBT When business, the first kind supplementary service is video class CRBT, and when calling party receives video class CRBT, required flow is larger.

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

Here, the supplementary service pushes log-on message, including but not limited to：

Calling part user number, calling party's wireless network IP address, gateway address (if present), port numbers, current The network rate of one network and when not accessing first network, if selection first kind supplementary service push.

Here, the supplementary service push log-on message can be stored in supplementary service server.

In this way, when supplementary service server receives supplementary service trigger request, it being capable of the quickly caller based on acquisition The supplementary service push log-on message registered before square information inquiry to calling party, to judge whether calling party accesses the One network, which provides, effectively to be supported.

It is described to judge whether calling party accesses first network in an optional embodiment, including：

In the present embodiment, the preset time can be pre-configured with according to network actual conditions or incorporate experience into.

In this way, calling party is to after the success of supplementary service server registration, periodically by first network to the additional industry Business server sends the first heartbeat message；In this way, whether supplementary service server can be according to receiving the first heartbeat message and sentences Whether disconnected calling party accesses first network.

It is described to judge whether calling party accesses first network in another optional embodiment, including：

Obtain the supplementary service push log-on message of the calling party；

Log-on message is pushed based on the supplementary service, sending the detection of first network connection status to the calling party asks It asks；

Wherein, the first network connection status response detected message, may include, but are not limited to following information：Calling party uses The network rate of family number, now first network.

In this way, after caller direction callee initiates to call, supplementary service server calling party's supplementary service before Log-on message, directly to calling party send out first network connection status probe requests thereby judge to lead according to the return information of calling party Whether the side of crying is current is in first network connection status.

Further, the method further includes：

Step 103：When determining that calling party does not access first network, the active calls network based on calling party is built with calling party Vertical second communication link transmits the second class in the supplementary service to calling party based on second communication link and adds industry Business.

Wherein, it is additional less than or equal to the first kind is received to receive flow needed for the second class supplementary service by the calling party Flow needed for business.

Here, the second class supplementary service can be audio class supplementary service.For example, when the supplementary service is CRBT When business, the second class supplementary service is audio class CRBT, and it is smaller that calling party receives flow needed for audio class CRBT.

It should be noted that under normal conditions, it is additional less than the first kind is received to receive flow needed for the second class supplementary service Flow needed for business.But in special circumstances, if the supplementary service push log-on message of the calling party obtained includes that calling party exists When not connected first network, the first kind supplementary service in push supplementary service is still selected, then, in step 103, described second Class supplementary service is first kind supplementary service.

In this way, under normal circumstances, in the state that calling party is not connected with first network, by the second communication link to caller The second class supplementary service of side's transmission；But if calling party is provided in the state of not connected first network, still in registration First kind supplementary service is pushed, then, in the state that calling party is not connected with first network, by the second communication link to caller Side's transmission first kind supplementary service.In such manner, it is possible in the case where being that calling party saves flow as possible, meet calling party to additional The diversification selection demand for services of business, also improves the flexibility for selecting to receive first kind supplementary service for calling party.

Caller is passed through when calling party is in the state of access first network using the technical solution of the embodiment of the present invention The first network that has accessed of side receives the first kind supplementary service of supplementary service server transmission, ensure that calling party can connect First kind supplementary service is received, is solved because some calling partys are because of the mobile data not supporting to be used for transmission first kind supplementary service The problem of service of first kind supplementary service can not be enjoyed caused by network；Simultaneously as calling party is without going through active calls Mobile data network used in callee receives first kind supplementary service, moreover it is possible to save because by mobile data network reception the A kind of supplementary service and the flow generated.In addition, when calling party is in the state of access first network, it can be according to current resident Network environment selection receives first kind supplementary service by first network, and the first network that calling party has preferably accessed receives The first kind supplementary service that supplementary service server is sent improves the flexibility that selection receives first kind supplementary service network. Further more, for the supplementary service implementation that some directly trigger based on calling terminal supplementary service server, and it is right In this kind of supplementary service implementation, hacker is easy to attack by terminal-pair supplementary service server, causes business paralysed Paralysis；However, technical solution described in the present embodiment is to complete, to the triggering of supplementary service server, to improve safety by core net Coefficient, there is no the hidden danger of fraud attack.

In the following, using first kind supplementary service as video frequency color ring, the second class supplementary service is audio CRBT, supplementary service service Device is color ring platform, first network is to illustrate for WI-FI network.

Color ring platform receives the Ring Back Tone service trigger request that core net is sent；Color ring platform is receiving supplementary service triggering When request, calling party information is obtained based on the trigger request；Judge whether calling party accesses WI-FI network, and is led determining When the side of crying accesses WI-FI network, WI-FI network communication link is established based on the WI-FI network and calling party, based on described WI-FI network communication link transmits video frequency color ring to calling party.In this way, when calling party is in the state of access WI-FI network, The WI-FI network accessed by calling party come receive color ring platform transmission video frequency color ring, ensure that calling party can receive To video frequency color ring, solves because of some calling partys the nothing caused by not supporting to be used for transmission the mobile data network of video frequency color ring Method enjoys the problem of video frequency color ring service；Simultaneously as calling party is without going through mobile number used in active calls callee Video frequency color ring is received according to network, moreover it is possible to save the flow generated because receiving video frequency color ring by mobile data network.

Embodiment two

An embodiment of the present invention provides a kind of transmission methods of supplementary service.Fig. 2 is the additional industry of the embodiment of the present invention one The flow diagram of the transmission method of business；As shown in Fig. 2, the method includes：

Step 201：When receiving supplementary service trigger request, calling party information is obtained based on the trigger request.

Step 202：Judge whether calling party accesses first network, if calling party accesses first network, executes step 203； If calling party does not access first network, step 204 is executed；

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

Here, judge that the mode whether calling party accesses first network includes：

By whether the first heartbeat message that calling party's timing is sent is received to judge, or

Directly first network connection status probe requests thereby being sent out to calling party, caller is judged according to the return information of calling party Whether Fang Dangqian is in first network connection status.

Step 203：The network rate of first network is obtained, step 205 is then executed；

Here, the mode for obtaining the network rate of first network includes：

It is obtained in the first heartbeat message sent by calling party's timing, or

First network network speed probe requests thereby directly is sent to calling party, is obtained from itself detection data that calling party returns It takes.

Step 204：The network rate of active calls network is obtained, step 208 is then executed；

Here, the mode of the network rate of active calls network is obtained, including：

It is obtained in the second heartbeat message about active calls network sent by calling party's timing, or

Active calls network network speed probe requests thereby directly is sent to calling party, from itself detection data that calling party returns It obtains.

Step 205：The first communication link is established based on the first network and calling party, then executes step 206；

Step 206：Registration is pushed in conjunction with the network rate of the first network and/or the supplementary service of the calling party Information and/or the supplementary service signing information of the callee, from the optional first kind supplementary service choosing in the supplementary service First kind supplementary service to be transmitted is selected, step 207 is then executed；

Optionally, the first kind to be transmitted is selected to add industry from the optional first kind supplementary service in the supplementary service Business, including：

In conjunction with the network rate of the first network, waited for from the optional first kind supplementary service selection in the supplementary service The first kind supplementary service of transmission；Or

In conjunction with the network rate of the first network and the supplementary service signing information of the callee, added from described Optional first kind supplementary service in business selects first kind supplementary service to be transmitted；Or

Log-on message is pushed in conjunction with the network rate of the first network and the supplementary service of the calling party, from described Optional first kind supplementary service in supplementary service selects first kind supplementary service to be transmitted；Or

In conjunction with the network rate of the first network, the supplementary service push log-on message of the calling party and the quilt The supplementary service signing information for the side of crying selects the first kind to be transmitted from the optional first kind supplementary service in the supplementary service Supplementary service.

In this way, can be selected for calling party higher-quality attached according to network environment different residing for calling party, network speed situation Add business tine.

Shift to an earlier date in this way, supplementary service server is currently located network condition, network speed situation and calling party according to calling party The supplementary service transmission requirement set, it is the supplementary service content for the best quality that calling party provides to pick out currently.

Specifically, the quality of the supplementary service content can be divided into high definition first kind supplementary service, SD from high to low A kind of supplementary service, smooth first kind supplementary service, the second class of high definition supplementary service, SD the second class supplementary service.

Here, the sequence of qualitative attribute quality is：High definition >=SD >=smoothness.

By taking supplementary service is Ring Back Tone service as an example, the quality of the Ring Back Tone service can be divided into from high to low：HD video is color Bell, SD video frequency color ring, smooth video frequency color ring, high definition audio CRBT, SD audio CRBT.

In a specific implementation mode kind, each supplementary service content is accompanied with for characterizing supplementary service content quality Qualitative attribute label or qualitative attribute mark.

In this way, after the classification that supplementary service server determines supplementary service content to be transmitted, it can be according to current resident The network rate of network determines the qualitative attribute being adapted with the network rate.

For example, supplementary service server is determined to calling party transmits first category supplementary service by first network, Judge that the network rate of now first network meets the requirement of high definition qualitative attribute, then selects high definition qualitative attribute for calling party First category supplementary service.

Optionally, for calling party, the push mode of first kind supplementary service can be set in advance, i.e.,：Whether only in caller Side is transmitted under first network, or even if permission supplementary service server is if when calling subscribe is in non-first network Calling party transmits first kind supplementary service.

Optionally, for callee, the supplementary service content of calling party's broadcasting can be set as in advance, can be one or Multiple, after callee completes the setting, supplementary service server will select in the supplementary service content library being arranged from callee Supplementary service content be adapted with current network conditions and network rate, top-quality, is transmitted to calling party.If called Fang Wei is specifically configured to the supplementary service content of calling party's broadcasting, but has opened supplementary service function, then supplementary service server The free supplementary service being adapted with current network conditions and network rate, top-quality in giving tacit consent to supplementary service content library Content is transmitted to calling party.

In a specific embodiment, the network rate of first network described in the combination and/or the calling party's is attached Add service propelling log-on message and/or the supplementary service signing information of the callee, from optional in the supplementary service A kind of supplementary service selects first kind supplementary service to be transmitted, including：

Supplementary service signing information based on the callee judges whether there is supplementary service corresponding with the callee Content library；

If so, from supplementary service content library corresponding with the callee selection and calling party currently resident the The supplementary service content that one network and its network rate are adapted；

If not provided, selection is resident first network and its network with the current of calling party from acquiescence supplementary service content library The adaptable supplementary service content of rate.

As an implementation, the selection and the current resident first network and its network rate of calling party are adapted Supplementary service content, including：

If existing simultaneously two or more current networks for being resident network and current resident network with calling party The adaptable supplementary service content of rate, then randomly choose a supplementary service content to be played.

It should be noted that here, the execution sequence of the step 205 and step 206 can be interchanged, alternatively, the two can To be carried out at the same time.

Step 207：The first kind in the supplementary service is transmitted to calling party add industry based on first communication link Business, then terminates flow.

Step 208：The second communication link is established based on the active calls network and calling party, then executes step 209；

Step 209：In conjunction with the network rate of the active calls network and/or the supplementary service push of the calling party The supplementary service signing information of log-on message and/or the callee add industry from optional second class in the supplementary service Business selects the second class supplementary service to be transmitted, then executes step 210；

It should be noted that here, the execution sequence of the step 208 and step 209 can be interchanged, alternatively, the two can To be carried out at the same time.

Step 210：The second class in the supplementary service is transmitted to calling party add industry based on second communication link Business, then terminates flow.

It should be noted that on the one hand, callee can specify the supplementary service content of broadcasting, can be an additional industry Business content, can also be multiple supplementary service contents；Can be that the first kind supplementary service of different quality or the second class add industry Business.After callee specifies the supplementary service properties collection of broadcasting, industry is added when supplementary service server is played to calling party When content of being engaged in, it is necessary to select current calling party acceptable most high-quality in the supplementary service properties collection specified from callee The supplementary service content of amount.It, can be from multiple playable when there are the supplementary service content of multiple playable phase homogenous quantities In the supplementary service content of phase homogenous quantities, random selection one is as supplementary service content to be played.
