Description
Technical Field
The present invention relates to a color ring back tone service of a wireless communication system, and in particular, to a method and a system for implementing a color ring back tone service for a 3GPP network.
Background
The color ring back tone service (personalized ring back tone service) refers to that a calling party listens to a color ring back tone when a called party is idle, and the personalized feature of the color ring back tone service is remarkable and obviously enhances the hearing feeling, so that the color ring back tone service is well developed in China and even east Asia telecommunication markets. At present, networking of various networks is diversified, and mobile switching center capabilities of equipment manufacturers are different, so that a color ring function needs to be provided by combining specific networking and mobile switching center capabilities.
In the existing 2G technology, there are two main ways to implement color ring back tone services. One is to add "color ring service" user attribute data in a mobile switching center/HLR (Home Location Register), and the mobile switching center adds the following functions: when the called terminal is idle, a speech path for playing the color ring tone is established to the color ring service center according to the color ring service data of the user, the color ring tone played by the color ring service center is transmitted to the calling party, and when the state of the called terminal is changed into non-idle (such as off-hook, overtime, no response and the like), the mobile switching center disconnects the speech path to the color ring service center.
This method requires the mobile switching center/HLR to make a large modification, needs to change the service data structure of the user and change the call processing flow, and currently, there is no relevant standard specification, the modification period in the actual engineering is long, and there are many involved equipment manufacturers, thereby causing a long construction period.
The other is to use a service subscription/service trigger of MSC (Mobile service Switching Center)/HLR (for example, in GSM subscription T-CSI, in CDMA network subscription _ TERMINATION, CALLED _ ROUTING _ ADDRESS _ AVAILABLE trigger, etc.), set service subscription/service trigger data for a user who needs to open a color ring service, when a call to a CALLED terminal occurs, the Mobile Switching Center triggers an intelligent network service logic, the intelligent network service logic instructs the Mobile Switching Center to connect the call to the color ring service Center, and finally, the color ring service Center completes the connection of the CALLED terminal and the playing of the color ring.
The mode has 'speech path circuitous', not only occupies extra speech path relay resources in the conversation process, but also depends on the stability of the color ring back tone service center. Another user only has one service signing/triggering device, and the conflict between the color ring back tone service and other intelligent network services exists.
The specification standard of 3GPP (the 3rd Generation Partnership Project) network provides new technologies that can be used to implement value-added services, and therefore a method for implementing a color ring back tone service according to the 3GPP specification standard is needed.
Disclosure of Invention
The invention mainly aims to provide a method for realizing a color ring back tone service for a 3GPP network and a system for realizing the color ring back tone service for the 3GPP network.
In order to achieve the above object, according to a first aspect of the present invention, the present invention provides a method for implementing a color ring back tone service for a 3GPP network. The method for realizing the color ring back tone service comprises the following steps:
step S102, setting the signing data for the color ring back tone service user on the HSS (Home subscriber Server) or HLR of the color ring back tone service user;
step S104, the calling terminal calls a color ring Service user as a called user, the MSC triggers the color ring guiding Service through SCP (Service Control Point), and continues the call to the called terminal;
step S106, SCP knows the called terminal is in idle state through MSC, and instructs MSC to set up call to color ring service center, and color ring service center starts playing color ring; and
step S108, SCP knows the idle state change of the called terminal through MSC, instructs MSC to cut off the speech path to the CRBT service center, and the calling user and the called user talk or call ends.
The subscription data may include a service key, an SCP address, and a subscription type flag.
If the subscription type is T-CSI (Terminating CAMEL subscription information ), the MSC may be an originating MSC or a GMSC (Gateway MSC). In step S104, the step of the MSC triggering the color ring guiding service on the SCP may include: after the originating MSC or GMSC obtains the subscription data from HSS or HLR, the coloring ring guiding service on SCP is triggered; the step of MSC continuing to call to the called terminal includes that the initial call MSC or GMSC continues to call to the roaming MSC of the called terminal and then continues to call to the called terminal. In step S106 and step S108, the step of the SCP knowing the status of the called terminal through the MSC may include: after receiving the message returned by roaming MSC, MSC reports the message to SCP.
If the subscription type is VT-CSI (VMSC Terminating CAMEL subscription Information, Terminating CAMEL subscription Information of the visited MSC), the MSC may be the visited MSC. In step S104, the step of the MSC triggering the color ring guiding service on the SCP may include: the call arrives at the visited MSC, and the visited MSC triggers the color ring guiding service on the SCP. In step S106 and step S108, the step of the SCP knowing the status of the called terminal through the MSC may include: after receiving the message returned by the wireless network, the MSC reports the message to the SCP.
In step S106, after MSC establishes a call to a color ring service center, SCP instructs MSC to separate a called end from a calling section 1, and moves the calling end to the color ring service center into the calling section 1, the color ring service center starts playing color ring, and a calling user hears the color ring; in step S108, after the MSC disconnects the voice path to the color ring back tone service center, the called end is moved into the calling segment 1, the calling party and the called party are in a conversation or the call is ended, and the color ring back tone service is ended.
In step S106, if the MSC can not receive the indication of SCP, the call is released or continued to the roaming MSC according to the no-response SCP parameter in the service parameter of the intelligent network defined by the called user locally.
The color ring service center can comprise an intelligent peripheral/service switching point functional module, and can process the incoming call and play the corresponding color ring according to the incoming call signaling.
In order to achieve the above object, according to a second aspect of the present invention, the present invention provides a system for implementing a color ring back tone service in a 3GPP network. The system for realizing the color ring back tone service comprises: HSS or HLR, which is used to store the contract signing data of color ring business user; MSC, used to trigger color ring guiding service, receive and report message, and establish and disconnect call; SCP for executing color ring guiding service logic, receiving message reported by MSC, indicating MSC to continue and establish call; and a color ring Service center, including an IP/SSP (Intelligent Peripheral/Service Switch Point) and possibly an SCP device thereof, for playing a color ring.
When the calling terminal calls the color ring service user, the MSC triggers the color ring guiding service on the SCP, continues to call to the called terminal, if the called terminal is in an idle state, the SCP instructs the MSC to establish a call to the color ring service center, the color ring service center starts playing the color ring, if the idle state of the called terminal is changed, the SCP instructs the MSC to disconnect the speech path to the color ring service center, and the calling user and the called user have a call or the call is finished.
The subscription data may include a service key, an SCP address, and a subscription type flag. If the subscription type is T-CSI, the MSC may be an originating MSC or a GMSC. If the subscription type is VT-CSI, then the MSC may be a visited MSC.
The protocol between the SCP and the MSC may be CAP 4. The protocol between the HSS or HLR and MSC may be MAP (Mobile Application Part). The IP/SSP and the MSC can comprise a No. 7 signaling connection and a speech path relay connection.
Through the technical scheme, the invention achieves the following technical effects. The method for realizing the color ring back tone service effectively plays the function of a 3GPP CAP (CAMEL application Part) protocol without any modification of MSC, GMSC and SCP. By the method, the color ring back tone service can be realized through intelligent network software development conforming to the standard, and a simple and easy method is provided for the CS (Circuit switching) domain of the 3GPP network to open the color ring back tone service. Meanwhile, the call connection and conversation between the calling party and the called party do not pass through the color ring service center, thereby avoiding the speech path circuitous
