Description
Technical Field
The present invention relates to a color ring playing technology in wireless communication, and in particular, to a color ring playing method and system, a Mobile Switching Center (MSC) at a calling side, and an MSC at a called side.
Background
The color ring back tone service is a music ring back tone service which has been developed in the mobile communication industry in recent years. In the process of dialing the called side by the calling side, the original 'beep, beep.' sound is replaced by the audio resources rich in the contents of songs, music, recording segments and the like, the songs, the music, the recording segments and the like are called as polyphonic ringtone ring tone resources, and the polyphonic ringtone ring tone resources are stored in the polyphonic ringtone platform system in a file form.
The current color ring back tone service is generally realized by a special color ring back tone calling platform, for example, a special color ring back tone service platform system is introduced into a communication network, and comprises a color ring back tone calling processing platform and a color ring back tone service processing platform; the system comprises a color ring calling processing platform, a color ring calling processing platform and a color ring calling processing platform, wherein the color ring calling processing platform is used for playing a color ring tone to a user in the calling process of a color ring user to realize color ring service presentation; the ring service processing platform completes the service management of the color ring user, for example: opening and closing the color ring back tone service, customizing the color ring back tone playing mode and the like. The polyphonic ringtone platforms are specially introduced into a communication network for polyphonic ringtone services, and correspondingly transform switch equipment of the communication network, such as MSC, specifically: firstly, a corresponding identifier needs to be added in a Home Location Register (HLR) and a Visitor Location Register (VLR) to mark a service attribute of a user, for example, whether the user is a color ring service user; secondly, the MSC needs to improve the call processing flow, for example, the MSC can trigger the following call flow according to the VLR color ring service identifier: the ring back tone resource of the local MSC is not connected any more, but a new ring back tone calling request is initiated to a ring back tone service calling platform capable of providing the ring back tone service, and the ring back tone service calling platform provides the ring back tone service.
The color ring back tone service determines the service providing mode due to the service characteristics and technical conditions, namely, the color ring back tone service is developed by adding a platform special for providing the color ring back tone service in a network instead of directly providing the color ring back tone service through switch equipment, and the reason is mainly that the color ring back tone service needs a special huge and rich color ring back tone resource library system, and the ring back tone resource library provides the customized personalized ring back tone of a user. The original telephone exchange equipment facing telephone call switching processing can provide certain specific audio segments as ring tones, but cannot provide users with the resources of the ring tones which are rich as those of the existing polyphonic ringtone platform, so the polyphonic ringtone service can be provided only by introducing the polyphonic ringtone platform, and the method has the following defects:
the call flow and procedure of the telephone exchange needs to be modified, and a call from the MSC to the polyphonic ringtone call platform is forced to be added in the call ringing phase, which is not necessary for the call between the calling party and the called party, and which is generated only for providing the polyphonic ringtone playing. Therefore, the calling between the polyphonic ringtone users becomes two calls, and the calling between the polyphonic ringtone users is different from the calling of the non-polyphonic ringtone users in flow, so that the polyphonic ringtone calling flow wastes network resources, causes the call flow between the polyphonic ringtone users and the non-polyphonic ringtone users to be non-uniform, and easily causes the network element node to break down.

Steps 101 and 102 in the embodiment of the present invention may be executed by the MSC on the calling side, and may also be executed by the MSC on the called side.
The embodiment of the invention describes a color ring playing method executed by a calling side MSC, as shown in FIG. 2, the method comprises the following steps:
step 201: when receiving a call request message initiated by a calling side, a calling side MSC sends a routing query message to an HLR to which the called side belongs.
Step 202: and when the HLR to which the called side belongs determines that the called side signs the color ring back tone service, the MSC at the calling side receives a routing query response message which is returned by the HLR to which the called side belongs and carries the sign of the signed color ring back tone service, and marks the call as a color ring back tone call.
Specifically, when a calling side MSC receives a call request message initiated by a calling side, a routing query message is sent to an HLR to which the called side belongs according to the number of the called side; when the HLR to which the called side belongs determines that the called side signs a color ring service, the MSC of the calling side receives a routing query response message returned by the HLR to which the called side belongs.
Therefore, the roaming number of the called side can be obtained through the interaction of the routing query.
Preferably, after step 202, the method further comprises:
the method includes that a calling side MSC sends an Initial Address Message (IAM) to a called side MSC, and receives an Address Complete Message (ACM) sent by the called side MSC when the called side MSC finds the called side.
Preferably, the method further comprises: and when the called side is in an idle state, the MSC at the calling side blocks the common echo ring returned by the MSC at the called side.
Preferably, when the HLR to which the called side belongs determines that the called side is not subscribed with the color ring back tone service, the MSC at the calling side receives a routing query response message carrying a common service identifier and returned by the HLR to which the called side belongs;
and the MSC at the calling side executes a common call flow between the calling side and the called side according to the route inquiry response message carrying the common service identifier.
Specifically, when the HLR to which the called side belongs determines that the called side does not sign the color ring service, the MSC at the calling side receives a routing query response message carrying a common service identifier, which is returned by the HLR to which the called side belongs; and the MSC at the calling side executes a common call flow between the calling side and the called side according to the route inquiry response message carrying the common service identifier.
Here, the common service identifier is different from the color ring back tone service identifier, and it can be determined that the current calling or called side has no color ring back tone service subscription through the common service identifier.
Here, the common call flow is a call flow of the non-polyphonic ringtone service, and specifically includes: the calling side MSC sends a call request message to the called side MSC according to the route inquiry response message carrying the common service identification, and the called side MSC directly plays a non-polyphonic ringtone ring, such as a 'beep sound' to the calling side.
Step 203: when the call is marked as a polyphonic ringtone call and the called side is in an idle state, the MSC at the calling side sends a polyphonic ringtone data query request message carrying the number information of the calling side and the number information of the called side to a polyphonic ringtone user data center.
Specifically, when the called side MSC determines that the called side is in an idle state, the called side MSC is notified; and the calling side MSC blocks the common echo ring returned by the called side MSC and sends a polyphonic ringtone data query request message carrying the number information of the calling side and the number information of the called side to a polyphonic ringtone user data center.
Step 204: and the calling side MSC receives a polyphonic ringtone data query response message which is returned by the polyphonic ringtone user data center and carries the polyphonic ringtone ring file path information, extracts a polyphonic ringtone ring file to be played to a polyphonic ringtone service ring resource cloud end according to the polyphonic ringtone ring file path information in the polyphonic ringtone data query message, and plays the polyphonic ringtone ring file to the calling side.
Preferably, the method further comprises: and when the called side is in a busy or call failure state, playing a recording notification for the calling side through the MSC of the called side.
Specifically, when the called side MSC determines that the called side is in a busy or call failure state, the recording notification is played to the calling side. Here, the recording notification is a one-end recording prompting that the called side is in a busy or call failure state, for example, "the user called by you is busy", or "the user called by you cannot get through".
The embodiment of the invention also discloses a color ring playing method executed by the called side MSC, as shown in FIG. 3, the method comprises the following steps:
step 301: when receiving the call request message initiated by the calling side, the calling side MSC sends a routing query message to the HLR to which the called side belongs; the MSC of the calling side receives a routing query response message returned by the HLR to which the called side belongs; and the calling side MSC sends an IAM to the called side MSC.
Preferably, before step 301, the method further comprises:
when receiving the call request message initiated by the calling side, the calling side MSC sends a routing query message to the HLR to which the called side belongs;
the MSC of the calling side receives a routing query response message returned by the HLR to which the called side belongs;
and the calling side MSC sends an IAM to the called side MSC.
Step 302: when a called side MSC receives an IAM sent by a calling side MSC, whether the called side signs a color ring service or not is inquired in a VLR (visitor location register) to which the called side belongs; when the called side signs the color ring service, the call is marked as the color ring call.
Preferably, the method further comprises: when the called side is not signed with the color ring service, the called side MSC marks the call as a common call and executes a common call flow between the calling side and the called side.
Here, the common call flow is a call flow of the non-polyphonic ringtone service, and specifically includes: the called side MSC directly plays the non-polyphonic ringtone ring tone, such as 'beep tone' to the calling side.
Preferably, after the call is marked as a color ring call, the method includes:
and when the called side MSC finds the called side, the called side MSC sends the ACM to the calling side MSC.
Step 303: when the call is marked as a polyphonic ringtone call and the called side is in an idle state, the MSC of the called side sends a polyphonic ringtone data query request message carrying the number information of the calling side and the number information of the called side to the polyphonic ringtone user data center.
Step 304: and the called side MSC receives a polyphonic ringtone data query response message which is returned by the polyphonic ringtone user data center and carries the polyphonic ringtone ring file path information, extracts the polyphonic ringtone ring file to be played to a polyphonic ringtone service ring resource cloud end according to the polyphonic ringtone ring file path information in the polyphonic ringtone data query message, and plays the polyphonic ringtone ring file to the calling side.
Preferably, the method further comprises: and when the called side is in a busy or call failure state, playing a recording notice for the calling side.
Specifically, when the called side MSC determines that the called side is in a busy or call failure state, the recording notification is played to the calling side. Here, the recording notification is a one-end recording prompting that the called side is in a busy or call failure state, for example, "the user called by you is busy", or "the user called by you cannot get through".
For the color ring back tone playing method described in fig. 2, the present invention also provides a preferred embodiment, as shown in fig. 4, including the following steps:
step 401: the calling side initiates a call request to the MSC of the calling side.
Step 402: after receiving the call request, the MSC at the calling side initiates a routing query message to the HLR to which the called side belongs according to the number of the called side so as to acquire the roaming number of the called side.
Step 403: the HLR of the called side inquires whether the called side is a subscription user of the color ring back tone service, if not, the HLR of the called side marks the called side as a common user in the returned route inquiry response message of the called side, and then executes a common call flow; if the called side is the subscriber of the color ring back tone service, the HLR to which the called side belongs marks the called side as the color ring back tone subscriber in the returned routing query response message of the called side.
Step 404: after receiving the route inquiry response message sent by the HLR to which the called side belongs, the calling side MSC marks the call as a color ring service call and sends an IAM to the called side MSC to start call connection.
Step 405: after receiving the IAM, the called side MSC returns ACM to the calling side MSC; judging the state of the called side, if the called side is busy or in call failure, the MSC of the called side will play the corresponding recording notice to the calling side; if the called side is in idle state, the MSC of the called side will play the common ring back tone to the calling side.
Step 406: if the called side is in an idle state, the MSC of the calling side starts a color ring calling processing flow according to the previous color ring calling mark, blocks the common ring back tone played by the MSC of the called side, and sends a color ring data query message carrying the number information of the calling side and the number information of the called side to a color ring user data center.
Step 407: after receiving the polyphonic ringtone data query message of the calling side MSC, the polyphonic ringtone user data center searches a polyphonic ringtone playing strategy customized by the called side in a polyphonic ringtone user database according to the number information of the calling side and the number information of the called side, which are carried in the polyphonic ringtone data query message, extracts the polyphonic ringtone ring file path information which should be played in the call, generates a polyphonic ringtone data query response message and returns the polyphonic ringtone data query response message to the calling side MSC.
Step 408: the method comprises the steps that a calling side MSC directly extracts a color ring tone file to be played in a call from a color ring tone service ring tone resource cloud end through an IP network according to color ring tone file path information carried in a color ring tone data query response message returned by a color ring tone user data center, and then plays the color ring tone file to the calling side, and the calling side listens the color ring tone.
Step 409: after the called side picks up the phone, the called side MSC returns answer response information to the calling side MSC; the MSC of the calling side stops playing the polyphonic ringtone ring tone file and establishes the call connection between the calling side and the called side.
Step 410: after the conversation is finished, the calling side and the called side release the circuit resources occupied by the call through the disconnecting message.
For the color ring back tone playing method described in fig. 3, the present invention further provides a preferred embodiment, as shown in fig. 5, including the following steps:
step 501: the calling side initiates a call request to the MSC of the calling side.
Step 502: after receiving the call request, the MSC at the calling side initiates a routing query message to the HLR to which the called side belongs according to the number of the called side so as to acquire the roaming number of the called side.
Step 503: the HLR of the called side inquires the called position information and returns the route inquiry of the called side, namely response information to the MSC of the calling side.
Step 504: after receiving the route inquiry response message sent by the HLR to which the called side belongs, the calling side MSC sends an IAM to the called side MSC to start call connection and connect a speech path.
Step 505: after the called side MSC receives the IAM, the VLR inquires whether the called side is a subscription user of the color ring back tone service, if not, the called side is marked as a common user, and then a common calling flow is executed; if the called side is the user signing the color ring back tone service, the called side is marked as the color ring back tone user.
Step 506: after the called side MSC pages and searches the called side, the ACM is returned to the calling side MSC; judging the state of the called side, if the called side is in busy state or call failure state, the called side MSC will play the corresponding recording notice to the calling side; if the called side is idle and not a color ring user, the called side MSC will play a common ring back tone to the calling side; if the called side is idle and the called side is a color ring user, the called side MSC starts a color ring calling processing flow and sends a color ring data query message carrying the number information of the calling side and the number information of the called side to a color ring user data center.
Step 507: after receiving the polyphonic ringtone data query message of the called side MSC, the polyphonic ringtone user data center searches a polyphonic ringtone playing strategy customized by the called side in a polyphonic ringtone user database according to the number information of the calling side and the number information of the called side carried in the polyphonic ringtone data query message, extracts the polyphonic ringtone ring file path information which should be played in the call, generates a polyphonic ringtone data query response message and returns the polyphonic ringtone data query response message to the called side MSC.
Step 508: the called side MSC inquires the path information of the polyphonic ringtone ring tone file carried in the response message according to the polyphonic ringtone data returned by the polyphonic ringtone user data center, directly extracts the polyphonic ringtone ring tone file to be played in the call from the polyphonic ringtone service ring tone resource cloud end through the IP network, and then plays the polyphonic ringtone ring tone file to the calling side, and the calling side listens to the polyphonic ringtone ring back tone.
Step 509: after the called side picks up the phone, the called side MSC returns answer response information to the calling side MSC; the called side MSC stops playing the polyphonic ringtone ring tone file and establishes the call connection between the calling side and the called side.
