Problems solved by technology

[0006] 2. The SIP device has no call priority control for multiple terminals of the same number called by SIP FORKING, and treats each terminal as an equal call object
However, the SIP FORKING function cannot be applied to the situation that the same number is assigned to multiple terminals with different priorities in an enterprise, that is, selective calls are realized according to setting different priorities for different terminals. This scenario can be applied to Enterprises provide staff with the same number, but these terminals are not at the same level and cannot be treated indiscriminately

Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] figure 1 Shows a flow chart of a method for enhancing the SIP FORKING call function provided by an embodiment of the present invention, such as figure 1 As shown, the steps include:

[0039] Step 101: setting priority for each terminal using the same SIP FORKING number;

[0040] Step 102: When the calling user dials the SIP FORKING number, the SIP device calls the terminals using the SIP FORKING number sequentially in order from the highest priority to the lowest priority;

[0041] Step 103: If the terminal responds to the call and goes off-hook, the SIP device terminates the call.

[0042] The above step 101 includes: the SIP device receives th...

Abstract

The invention discloses a method and a device for strengthening SIP FORKING call function. The method comprises the following steps: priority is set for each terminal using the same SIP FORKING number; when a call subscriber calls the SIP FORKING number, a SIP device sequentially calls terminals using the SIP FORKING number according to the sequence from the highest priority to the lowest priority; if one terminal responds the call off-hook, the SIP device stops calling. Through providing a call control function, the strengthened SIP FORKING function of synchronous terminal ringing at the same priority and sequential terminal ringing at different priority is realized; and service open interfaces are provided to a service control module, so that the call control function that the service control module selects the connected terminal is achieved.

Description

technical field [0001] The present invention relates to the field of next generation network (Next Generation Network, NGN) soft switch, in particular to a method and equipment for enhancing session initiation protocol (Session Initiation Protocol, SIP) forking (FORKING) call function applied to NGN. Background technique [0002] In the field of NGN softswitching, the SIP protocol is generally used to realize the call control function. Among them, the SIP FORKING function enables multiple terminals of the soft switch to register the same number. After this number is called, all registered terminals with the same number registered on the soft switch will ring at the same time. When one of the terminal calls is answered, other calls will ring. Hang up. The traditional SIPFORKING mechanism can only realize simple same-number registration and simultaneous calling functions; this function can only open the results of SIP FORKING calls to the business, and the business has insuff...
