Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be fully conveyed to those skilled in the art. Nothing in the following detailed description is intended to suggest that any particular component, feature, or step is essential to the invention. Those skilled in the art will understand that various features or steps can be substituted for each other or combined without departing from the scope of the present disclosure.

Fig. 1 shows a flowchart of a method for bridging multiple call protocols based on a call router according to an exemplary embodiment of the present disclosure. Fig. 2 shows another schematic diagram of a method for bridging multiple call protocols based on a call router according to an exemplary embodiment of the present disclosure. This disclosure proposes a method for bridging multiple call protocols based on a call router, including steps: S1, selecting a first call protocol P1 and a second call protocol P2 from the various call protocols, and converting the The registration information of the first call protocol P1 and the second call protocol P2 is reported to the call router, and the call router sends the registration information (for example, number) of the first call protocol P1 and the second call protocol P2 ) to bind. Specifically, the multiple call protocols may include protocols such as SIP, DECT, HTTP, and PSTN. Preferably, the first call protocol P1 may be SIP and the second call protocol P2 may be DECT. S2. The call router may set a call rule according to the registration information of the first call protocol P1 and the second call protocol P2 and the bound registration information. For example, for a call protocol that supports multiple lines, call rules specify the forwarding policy for each line. Specifically, the registration information may include number, line, and online status. In addition, it is also necessary to ensure that the calling router can be notified in time when the registration information changes to prevent the call from being missed. The bound registration information is, for example, the information that the number of the first call protocol P1 is bound with the number of the second call protocol P2. S3 encapsulates and extracts signaling parts of the first call protocol P1 and the second call protocol P2 according to the call rule set by the call router, so as to obtain communication signaling. For example, the communication signaling may include incoming, ring, inviting, trying, alerting, talking, ending, idle, transfer. In addition, the above communication signaling may correspond to the call status code in the SIP protocol. For example, ring may correspond to 180 in the SIP protocol, trying may correspond to 100 in the SIP protocol, ending may correspond to 487 in the SIP protocol, etc., so as to ensure compatibility with the SIP protocol. S4. According to the call rule set by the call router, parse the SDP part of the first call protocol and the second call protocol to obtain a data encoding format. For example, parse the SDP part of the SIP call protocol and the DECT call protocol to obtain the encoding format of the data, such as media type (video or audio), transmission protocol (UDP or IP), media format (H.261 or MPEG), etc. . S5. When the external number N3 calls the number N1 of the first call protocol P1, the call router, for example, uses the registration information and the bound registration information to determine the number N1 of the first call protocol P1 and the number N1 of the second call protocol P2. The number N2 is a binding relationship (for example, the number N1 and the number N2 are bound together), and then establish a call with the number N1 of the first call protocol P1, and dial the number N2 of the second call protocol P2 at the same time, And establish a call with the number N2 of the second call protocol P2, and then the call router uses the RTP protocol to forward the data of the first call protocol P1 to the second call protocol P2 based on the encoding format of the obtained data and forward the data of the second call protocol P2 to the number N1 of the first call protocol P1. That is to say, as known to those skilled in the art, the data of the first call protocol P1 is forwarded to the entity (for example, equipment, module or program, etc.) corresponding to the number N2 of the second call protocol P2 ), and forward the data of the second call protocol P2 to the entity (for example, equipment, module or program, etc.) corresponding to the number N1 of the first call protocol P1, but other means in the art are not excluded . So far, the external number N3 establishes a conversation relationship with the calling router, and the calling router establishes a conversation relationship with N2. The voice data of the external number N3 is sent to the calling router, and the voice data of N2 is sent to the calling router. At this time, the calling router forwards the two data , which is equivalent to establishing a call between N3 and N2. Therefore, the effect of bridging the SIP protocol and the DECT protocol through the calling router is realized.

In a preferred embodiment, the method for bridging multiple call protocols based on a call router further includes: when the number N2 of the second call protocol P2 needs to be called, sending incoming signaling to the call router, and the call The router establishes a call with the number N2 of the second call protocol P2, and at the same time dials and calls the number N1 of the first call protocol P1 and establishes a call with it, and at the same time, the call router uses the RTP protocol to transfer The data of the second call protocol P2 is forwarded to the number N1 of the first call protocol P1, and the data of the first call protocol P1 is forwarded to the number N2 of the second call protocol P2.

In a preferred embodiment, when the number N1 of the first call protocol P1 needs to be called, the incoming signaling is sent to the call router, and the call router establishes a call with the number N1 of the first call protocol P1, At the same time dial the number N2 of the second call protocol P2 and establish a call with it, and at the same time, the call router uses the RTP protocol to forward the data of the first call protocol P1 to the second call based on the encoding format of the obtained data. the number N2 of the call protocol P2, and forward the data of the second call protocol P2 to the number N1 of the first call protocol P1.

The technical scheme of the present invention adopts the above-mentioned method and equipment, so that two protocols such as SIP and DECT can be simultaneously supported in the VOIP product. Aiming at the incompatibility of the existing call protocols, multiple protocols can be bridged to achieve the goal of protocol compatibility.
