Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and an apparatus for transmitting a ringing message. BACKGROUND OF THE INVENTION T1 and E1 (digital trunk circuit) are physical connection technologies, which are digital networks, which can be coaxial cables or optical fibers. T1 is a US standard with a bandwidth of 1.544 Mbps, El is a European standard, and has a bandwidth of 2.048 Mbps. Multiple standard channel signaling is supported on the /T1 digital trunk line. Each signaling standard is not uniform. For example, RITU-T standard Q.400-Q.490 defines the R2 signaling standard, but different countries and regions have their own implementation methods. For example, there is Nol signaling in China. Europe, Latin America and some developing countries have their own norms, such as Brazil R2, Argentina R2, etc., and each country has non-uniform standards due to non-uniform equipment, especially Russian channel signaling (R1.5). The signaling system is a relatively complex signaling system. The line signaling includes: City Network 2CAS, Rural Network 2CAS, 1-bit CAS (also known as NORKA Signaling), 2600Hz Signaling, and Three-wire trunk signaling. Each of the above types of signaling is further subdivided into two types of signaling: a CL/Local Switched Network (OCL) and a Trunk Connection Line (TCL); a single frequency of 1600HZ/2100HZ Signaling, 1200HZ and 1600HZ dual-frequency carrier signaling, 600HZ and 750HZ dual-frequency carrier signaling. In modern communication systems, the Public Switched Telephone Network (PSTN) smooth evolution to NGN is the best solution for the transformation of the existing network. The PSTN circuit time division multiplexing (TDM) is adopted. Different docking stations, different protocol versions to adapt to the purpose of docking the site, but after NGN, call users between different gateway nodes, you need to connect multiple packet switches (Private Branch Exchange, PBX for short) to the same gateway device. Devices, where different PBXs may have different levels of support for the protocol. The general associated standard includes line signaling and sender signaling. The ringing function is implemented by the called state control of the sender signaling. In the R1.5 signaling system, the implementation process is followed. The ringing function is controlled by the called state of the sender signaling, but the TCL sub-protocol can simultaneously select to transmit the ringing message through the line signaling to control the terminal to play the sound. In the TCL sub-protocol, the signaling can be sent by the sender. The called state controls the ringing function, and the ringing message can also be sent through the line signaling to control the terminal to play the sound. However, in the manufacture of the terminal device, the implementation of the ringing function of the terminal device does not completely correspond to the protocol. For example, in the TCL sub-protocol, the protocol defines that the terminal device can control the ringing by the called state of the sender signaling. Function, it is also possible to send a ringing message through line signaling to control the terminal to play the sound. However, the terminal device is set at the time of manufacture to control the ringing function only by the called state of the sender signaling, and therefore, is received at the terminal device. When the line signaling is received, the line signaling is released as abnormal signaling, and the ringing message is not sent through the line signaling to control the terminal to play. Therefore, the line signaling does not play its practical significance. However, the gateway device still sends the line signaling to the terminal device, thereby causing the transmission of the line signaling without actual meaning and causing waste of resources. In addition, there is also a scenario in which a protocol supported by a terminal can control a ringing function by a called state of a sender signaling, or a ringing message can be sent by a line signaling to control a terminal playing, a terminal device At the time of manufacture, it is set to control the playback of the terminal only when the line signaling is received, so that in some scenarios, the ringing message must be sent through the line signaling to control the terminal to play. Therefore, in the above related art, there is a problem that resources are wasted due to the gateway device transmitting line signaling that does not make sense. SUMMARY OF THE INVENTION The present invention provides a method and apparatus for transmitting a ringing message to at least solve the problem of resource waste caused by a gateway device transmitting line signaling that does not make sense in the related art.

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The embodiment provides a method for transmitting a ringing message. As shown in FIG. 1, the method for transmitting the ringing message includes steps S102 to S104. Step S102: Acquire configuration information corresponding to the PBX terminal, where the configuration information includes indication information of a manner of transmitting ringing information to the PBX terminal. Step S104: Send ringing information to the PBX terminal according to the indication information. Through the above steps, the configuration information of the PBX terminal is first obtained to obtain the indication information of the manner of transmitting the ringing information to the PBX terminal, and then the ringing information is sent to the terminal according to the indication information, so that the ringing can be sent according to the PBX terminal. The indication information of the manner of information selectively transmits the ringing information. For example, when the PBX terminal allows the ringing information to be transmitted through the line signaling, the manner of transmitting the ringing information through the line signaling may be selected, in the PBX terminal. When the ringing information is not allowed to be transmitted through the line signaling, the ringing information may be sent to the PBX terminal by means of the sender signaling, so as to prevent the PBX terminal from transmitting the ringing information through the line signaling. The ringing information is also sent through the line signaling.

Efficient transmission saves the resources needed to send the associated signaling. In order to accurately transmit the ringing information to the PBX terminal according to the indication information, in the preferred embodiment, before acquiring the configuration information of the PBX terminal, the manner of transmitting the ringing information reported by the PBX terminal to the PBX terminal is received; Configure the configuration information of the PBX terminal in the manner of information. In the above preferred embodiment, the manner of transmitting the ringing information to the PBX terminal is first obtained, and then the configuration information of the PBX terminal is configured according to the method of transmitting the ringing information. The manner of transmitting the ringing information to the PBX terminal may be when the PBX terminal is connected. Some information, for example, the protocol supported by the PBX terminal, through which the PBX ends The ringing function can be implemented by the terminal, and the configuration information can be used by the PBX terminal to control the ringing function, so as to accurately transmit the ringing information to the PBX terminal according to the indication information, and at the same time, for each The manner in which the PBX terminal sends ringing information is that the PBX terminal configures its own configuration information, which can realize the requirement of docking PBX terminal devices with different ringing functions. For example, according to multiple vendors of the on-site PBX terminal, the R1.5 protocol The support is slightly different, especially the implementation of the ringing function. The above configuration information may be implemented by means of the relay group circuit attribute flag configuration, and the method for transmitting the ringing information for each PBX terminal is configured for the PBX terminal. The configuration information (that is, the circuit attribute flag configuration) can realize the requirement of docking PBX terminal devices with different ringing functions. In order to avoid the transmission of the resources caused by the associated signaling, in the preferred embodiment, a preferred method for transmitting ringing information to the PBX terminal according to the indication information is provided, for example, the indication information indicates that the PBX terminal allows the transmission of the line information. When the ringing information is received, the ringing information is transmitted to the PBX terminal by line signaling. In the above preferred embodiment, in the case where the indication information indicates that the PBX terminal allows the ringing information to be received through the line signaling, the ringing information is transmitted to the PBX terminal through the line signaling, if the indication information indicates that the PBX terminal is not allowed to pass the line signaling. After receiving the ringing information, the ringing information is not sent to the PBX terminal through the line signaling, and the line signaling is discarded as abnormal signaling due to the fact that the PBX terminal does not recognize the line signaling after the transmission of the line signaling, thereby causing Waste of resources. In order to improve the flexibility of the embodiment, in the preferred embodiment, a preferred method for transmitting ringing information to a PBX terminal according to the indication information is provided, for example, the indication information indicates that the PBX terminal is not allowed to receive through the line signaling. In the case of ringing information, ringing information is transmitted to the PBX terminal by the sender signaling.

It is realized that the ringing information can be selectively transmitted according to the indication information of the manner of transmitting the ringing information to the PBX terminal. For example, when the PBX terminal allows the ringing information to be transmitted through the line signaling, the line signaling can be selected. When the ringing information is sent by the PBX terminal, the ringing information may be sent to the PBX terminal by means of the sender signaling, so that the PBX terminal is not allowed to pass the PBX terminal. When the line signaling is used to send the ringing information, the ringing information is also sent through the line signaling. However, the line signaling may not be recognized by the PBX terminal and is released, so that the line signaling cannot achieve its true meaning and waste resources. The problem is that the effective transmission of the associated signaling is improved, and the resources required for transmitting the associated signaling are saved. In order to accurately transmit the ringing information to the PBX terminal according to the indication information, in the preferred embodiment, as shown in FIG. 3, the transmitting device of the ringing message further includes: a receiving module 206, configured to receive the report reported by the PBX terminal The manner in which the PBX sends the ringing information; the configuration module 208 is connected to the receiving module 206, and configured to configure the configuration information of the PBX terminal according to the manner of transmitting the ringing information.

In the case of receiving the ringing information, the ringing information is transmitted to the PBX terminal through the line signaling. In order to improve the flexibility of the embodiment, in the preferred embodiment, as shown in FIG. 4, the foregoing sending module 204 further includes: a second sending unit 2044, configured to indicate, in the indication information, that the PBX terminal is not allowed to receive through the line signaling. In the case of ringing information, ringing information is transmitted to the PBX terminal by the sender signaling.

The above preferred embodiments are described in detail below with reference to the accompanying drawings and examples. For example, the method for transmitting the ringing message can be well used in an integrated media gateway of a Next Generation Network (NGN), and the E1 subunits associated with each group of relay circuits are connected to different PBX terminals. The device, by configuring whether the relay group sends an attribute flag of the ringing message (corresponding to the foregoing configuration information), whether to send a ringing message to the connected terminal device through the line signaling, thereby controlling the normal ringing of the PBX terminal. Features. As shown in FIG. 6, the transmitting apparatus for implementing the ringing message may include a service control module 602 (corresponding to the first obtaining module 202 and the sending module 204), and a relay resource management module 604 (corresponding to the receiving module 206 and the configuration module 208). The detection module 210 and the second acquisition module 212) and the signaling codec module 606 can implement the transmission of the ringing message between the modules by the following communication. The traffic control module 602 receives the inter-office signaling forwarded by the softswitch device 608, and the inter-office signaling includes carrying the vibration. For line signaling of the ring message, the service control module 602 analyzes the information content of the inter-office signaling according to a protocol (for example, H.248 protocol or SIP protocol), and if the information is analyzed from the information content of the inter-office signaling, the called party is analyzed. For the idle information, the service control module 602 determines whether to send a ringing message according to whether the flag of the processing ringing message (corresponding to the indication information in the configuration information) is configured on the relay resource management module 604, when the relay resource management module 604 is configured. When the flag of the ringing message is configured (the instruction information in the configuration information indicates that the PBX terminal is allowed to receive the ringing information through the line signaling), the service control module 602 sends the interoffice signaling to the signaling codec module 606. The inter-office signaling sent by the service control module by the signaling codec module 606 according to the management information of the relay resource management module Line coding, and the encoded standard signaling is transmitted to the docking device (equivalent to the PBX terminal) through the trunk line; when the flag of the ringing message is not configured on the relay resource management module 604 (equivalent to the configuration information) The indication information indicates that the PBX terminal does not allow the ringing information to be received through the line signaling. The service control module 602 does not send the interoffice signaling to the signaling codec module 606, and does not encode or decode the ringing message, and selects other methods. To implement ringing of the PBX terminal, for example, sending ringing information to the PBX terminal by means of the sender signaling, thereby implementing docking with different PBX terminals, and selectively selecting according to the configuration information of the PBX terminal. The associated channel signaling is sent to control the ringing function of the PBX terminal. At the same time, the signaling codec module 606 receives the standard signaling from the trunk line, and decodes and reports the service control module 602 (the module is set to control of the call flow). FIG. 7 is a flowchart of another method for transmitting a ringing message according to an embodiment of the present invention. As shown in FIG. 7, the method for transmitting the ringing message includes steps S702 to S722.

Step S704: The management information of the foregoing relay resource management module 604 is transmitted to the signaling codec module 606 and the service control module 602, where the management information includes configuration information. Step S706: The relay resource management module 604 notifies the signaling codec module 606 and the service control module 602, the signaling codec module 606, and the service control module 602 after detecting the configuration information change (for example, the protocol supported by the PBX terminal changes). Re-acquire new configuration information. Step S708: The service control module 602 receives the inter-office signaling forwarded by the softswitch device 608, and analyzes the information content of the inter-office signaling according to the protocol standard. Step S710: The service control module 602 determines whether to send the ringing message according to the configuration information, if the information of the called idle information is obtained from the information content of the inter-office signaling, if the configuration flag is configured, the process proceeds to step S712. Otherwise no ringing message is sent. Step S712: The service control module 602 sends the interoffice signaling to the signaling codec module 606, where the interoffice signaling includes line signaling carrying a ringing message. Step S714: The signaling codec module 606 encodes the interoffice signaling delivered by the service control module 602 according to the management information of the relay resource management module. Step S716: The signaling codec module 606 transmits the encoded standard signaling to the trunk line. Step S718: The signaling codec module 606 receives the standard line signaling from the trunk line and performs decoding according to the management information of the relay resource management module 604. Step S720: The signaling codec module 606 reports the decoded standard signaling to the service control module 602. Step S722: The service control module 602 receives the decoding information and performs call flow control. Through the above steps, the call flow for selectively transmitting the ringing message is implemented to meet the connection requirements of different PBXs supporting the R1 5 protocol.
