Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method and a gateway for detecting call identification information. BACKGROUND OF THE INVENTION In modern communication systems, in order to bring a good user experience to users, a variety of multifunctional intelligent upper layer services, including caller ID, are realized. Telephone caller identification information transmission and reception (commonly known as caller ID), referred to as Call Identification Identify (CID), is a service item provided by the telecommunication office to the called telephone user, and refers to the called user terminal equipment. A service item that displays caller identification information such as calling telephone number, calling party name, calling date and time, and stores it for the user to view. The called user decides whether to answer the call according to the displayed caller identification information, and can avoid some unwilling to answer or unfriendly calls. This function can be used to perform telephone network data communication for frequency-shift keying (FSK, Frequency-Shift Keying) information decoding, and is applied to real life. The basic method for realizing the telephone caller identification service is that the program switch on the calling side transmits information such as the calling telephone number to the terminal gateway on the calling side through the interoffice command system, and the CID chip of the terminal gateway on the calling side will The caller identification information is transmitted to the called subscriber's terminal switching device in the FSK mode before the first ringing or the second ringing interval. China's communication industry standards clearly stipulate that the caller ID service of the calling party is provided by the FSK method. In a call, if the called user applies for the CID service, the terminal exchange of the telecommunication office transmits the caller identification information data to the called user. At the same time, the terminal switch on the calling side often receives some call information, incoming number, user type, call time and other information on the calling end of the communication terminal to the terminal switch on the calling side, and the terminal switch on the calling side. The FSK chip on the terminal media gateway on the calling side is also reported to the FSK mode information sent by the terminal device on the calling side to the gateway on the calling side. The terminal gateway on the side is transmitted to the called gateway of the destination office by means of inter-office signaling. In the above CID data transmission process, the CID data transmitted through the interoffice command system is correct, but a fault occurs when the gateway sends the message to the user, and an error condition occurs when the user terminal displays, such as no content or display content. Incomplete, or garbled.

The above-described gateway structure has been described above, and the first embodiment will be described in detail based on the above-described gateway structure. Referring to the flowchart of the first embodiment shown in FIG. 2, the method includes the following steps: Step 200: The media gateway receives the call identification information of the calling side delivered by the inter-office signaling, and the service control module performs the call identification information that is sent by the service control module. decoding. Step 201: The service control module of the media gateway controls the preparation work of the CID coding module, including occupying CID resources, initializing CID resources, and the like. Step 202: The service control module of the media gateway controls the preparation of the FSK decoding module to check the CID code stream information, including the operation of occupying the FSK resource and initializing the FSK resource. Step 203: The service control module of the media gateway connects the CID encoding module to the FSK decoding module on the time slot of the time slot switching network T network, and prepares a path for the CID encoding module to the FSK decoding module to transmit the code stream. Step 204: The service control module of the media gateway sends the explicit content [A] and the FSK detection flag to the CID encoding module, and displays the content [A] in the module data area. In the present embodiment, the information of the CID is not limited to the content to be displayed [A], but may be other personalized signature information or the like. Step 205: The CID encoding module of the media gateway encodes the content [A], and sends the encoded information to the end office for display, and when the FSK detection flag is true, and sends the encoded content to the FSK decoding module. Step 206: When receiving the encoded stream sent by the CID encoding module, the FSK decoding module in the media gateway decodes the content into the content [B], and reports the decoded content to the service control module. Step 207: The service control module of the gateway compares the decoding information [B] of the FSK decoding module with the call information [A] stored in the data area of the module in 204. If the same, step S208 is performed; if not, step S209 is performed; Step 208: The service control module of the media gateway determines, according to the result of the comparison, that if the same, the CID encoding module works normally.

Step 303: The service control module of the media gateway connects the CID encoding module to the FSK decoding module on the time slot switching network T network, and prepares a path for the CID encoding module to the FSK decoding module to transmit the code stream. Step 304: The service control module of the media gateway sends the display content [A] and the FSK detection flag to

CID encoding module. In the present embodiment, the information of the CID is not limited to the content to be displayed [A], but may be other personalized signature information or the like. Step 305: The CID encoding module of the media gateway sends the encoded content to the FSK decoding module according to the FSK check flag being true. Step 306: When receiving the encoded stream sent by the CID encoding module, the FSK decoding module in the media gateway decodes the content into content [B], and sends the decoded content to the service control module. Step 307: The service control module of the gateway compares with the calling call information [A] after receiving the bishop information [B] reported by the FSK decoding module. If the same, step S308 is performed. If not, step 4 is performed. S309: Step 308: The service control module of the media gateway determines, according to the result of the comparison, that if the same, the CID encoding module works normally. Step 4 is performed to gather S310. Step 309: The service control module of the media gateway, according to the result of the judgment, if the difference is not the same, the CID coding module works abnormally and issues an alarm signal. Go to step 311. Step 310: The CID encoding module encodes the displayed content [A], and sends the encoded information to the end office or the user. Go to step 311. Step 311: The CID resource work check of the media gateway ends, and the occupied CID coding module resource and the FSK decoding module resource are released. In the second embodiment, the service control module of the media gateway determines, according to the result of the comparison, if the same, notifies the CID encoding module, the CID encoding module encodes the call identification information of the calling side and sends it to the end office or the user for caller ID display.
