Abstract

The invention discloses a method for allowing a dispatching desk to quickly refuse a blacklist incoming call of a loop trunk, which comprises the following steps: making the incoming call by a calling subscriber to loop trunk equipment by the means of an outer wire, wherein the calling subscriber occupies the loop trunk equipment; releasing the loop trunk equipment when the blacklist configured by the loop trunk equipment conforms to the calling number, hanging on the outer wire again after the outer wire is hung up through the loop trunk equipment, and terminating the calling. According to the method, the problem of repeated occupation of the loop trunk equipment of the blacklist user after the incoming call of the blacklist user is refused is solved. In addition, after the blacklist user is refused, the outer wire is hung up at one time, so as to effectively avoid repeated occupation of the loop trunk equipment of the blacklist user.

Description

The method of a kind of quick refusal loop trunks blacklist incoming call

Technical field

The present invention relates to a kind of method of refusing the loop trunks incoming call, relate in particular to a kind ofly when loop trunks equipment is received the blacklist calling number, loop trunks equipment is refused the method for relaying incoming call fast with the outside line off-hook, belongs to the dispatching communication technical field.

Background technology

Loop trunks (claiming again analog junction) equipment is not adopt signaling, directly uses the communication equipment of ordinary telephone line transferring voice and data.When the call outside line of outer office, the outside line ALERTING message reception incoming call that loop trunks equipment connects by detecting it.Because loop trunks equipment does not have signaling, before loop trunks equipment is with the outside line off-hook, can't discharge this calling.As long as the caller of incoming call is permanent, can hear ring-back always, the always ring of outside line meeting of calling is until ringing timeout just can discharge this calling.In this case, the loop trunks equipment that is connected with outside line can be occupied again and again, initiatively call release.Other want the calling of this loop of incoming call also can't incoming call because outside line does not discharge.When using, reality has following problem:

As shown in Figure 1, in loop trunks equipment, no matter be that DID(directly enters mode) or BID(two-stage dialing mode), when the blacklist caller incoming call of disposing on the loop trunks equipment, loop trunks equipment is occupied after the outside line ring.Its analysis calling number conforms to the blacklist of loop trunks equipment configuration, loop trunks equipment can be discharged, and at this moment not with the outside line off-hook, so or outside line can't be stopped ring.Outside line is ring always, and loop trunks equipment will continue occupied.After loop trunks equipment was occupied, it analyzed the blacklist of calling number and the configuration of loop trunks equipment again.When calling number with after blacklist conforms to, again loop trunks equipment is discharged.So repeat to circulate down, until calling subscriber oneself hangs up, and loop trunks equipment also can only be occupied again and again, can't once incoming call be discharged always.

Summary of the invention

For the existing deficiency of prior art, technical problem to be solved by this invention is to provide the method for a kind of quick refusal loop trunks blacklist incoming call.In the method, loop trunks equipment can directly with the outside line off-hook, be refused the relaying incoming call fast.

For realizing above-mentioned goal of the invention, the present invention adopts following technical scheme:

The method of a kind of quick refusal loop trunks blacklist incoming call is characterized in that: as calling subscriber during by outer alignment loop trunks equipment incoming call, described calling subscriber takies described loop trunks equipment;

When the blacklist of described loop trunks equipment configuration conforms to calling number, discharge described loop trunks equipment, again by described loop trunks equipment with the outside line off-hook after again with the outside line on-hook, this end of calling.

Wherein more preferably, described calling subscriber takies after the described loop trunks equipment, and described loop trunks equipment detects calling number according to External Call.

Wherein more preferably, described loop trunks equipment is compared according to the blacklist of described calling number and the configuration of described loop trunks equipment.

Wherein more preferably, the step of loop trunks equipment release External Call further comprises:

Described loop trunks equipment is with the outside line off-hook;

The corresponding incoming call of calling subscriber becomes talking state;

Described loop trunks equipment discharges External Call with the outside line on-hook, and the calling subscriber hears busy tone.

The present invention directly once with the outside line on-hook, prevents that blacklist caller circulation incoming call from taking the resource of loop trunks equipment in the permanent situation of blacklist caller.

Description of drawings

Fig. 1 is in the prior art during blacklist caller incoming call loop trunks equipment, repeatedly takies the schematic flow sheet of loop trunks equipment in the permanent situation of caller;

Fig. 2 is among the present invention during blacklist caller incoming call loop trunks equipment, refuses fast the schematic flow sheet of incoming call.

Embodiment

The present invention is described in further detail below in conjunction with the drawings and specific embodiments.

The method of quick refusal loop trunks blacklist provided by the invention incoming call not only can be applied to dispatching patcher, can also be applied to not have the calling system of dispatching desk.The below is described in detail as an example of calling system example.

This calling system comprises loop trunks equipment, outside line and caller phone, and loop trunks equipment comprises loop trunks plate and loop trunks processing module, and wherein loop trunks plate and loop trunks processing module are known prior aries, do not repeat them here.When the calling subscriber of outer office phone calls out outside line, the outside line ALERTING message reception incoming call that loop trunks equipment connects by detecting it.Loop trunks equipment can be always occupied, until the calling party telephone on-hook just is released.

In order to prevent that the calling subscriber from taking loop trunks equipment repeatedly, the invention provides the method for a kind of quick refusal loop trunks blacklist incoming call, be used in the calling subscriber in analogue loop incoming call process.As calling subscriber during by outer alignment loop trunks equipment incoming call, this calling takies this equipment.Loop trunks equipment is according to its concrete configuration, when blacklist and calling number when relatively being consistent, with behind the outside line off-hook again with the outside line on-hook, until the calling subscriber hears the calling busy tone, end of calling this time.The below is described in detail.

As calling subscriber during by outer alignment loop trunks equipment incoming call, no matter be that DID(directly enters mode) or BID(two-stage dialing mode), this equipment is occupied after the outside line ring.The loop trunks device analysis goes out calling number and conforms to the blacklist of loop trunks equipment configuration, and at first with the outside line off-hook, with the outside line on-hook, the calling subscriber hears busy tone again, and this is called out directly and finishes.Concrete measure comprises the steps: as shown in Figure 2

1) calling subscriber calls out outside line key, the outside line ring;

2) the loop trunks equipment Inspection that links to each other with outside line is after ring, and this calling subscriber's calling takies corresponding loop trunks equipment;

3) after the outside line ring, outer line interface is received the FSK(frequency shift keying) calling number;

4) loop trunks equipment occupied after, the loop trunks plate detects calling number and notifies loop relay process module;

5) the loop trunks processing module is compared the blacklist list of calling number and the configuration of this loop trunks equipment, judges that whether calling number conforms to the blacklist caller of this loop trunks equipment configuration, if conform to, then discharges loop trunks equipment.

6) loop trunks equipment passes through first the loop trunks plate with the outside line off-hook, and this equipment passes through the loop trunks plate with the outside line on-hook again by becoming talking state between outside line and the calling subscriber at this moment;

7) calling subscriber hears busy tone, refuses this incoming call, end of calling.

In the present invention, when the calling subscriber conforms to the blacklist caller of loop trunks equipment configuration, after this calling subscriber's incoming call, this equipment passes through the loop trunks plate with the again on-hook of outside line elder generation's off-hook, the calling subscriber hears busy tone, avoided in the permanent situation of caller, the blacklist caller repeatedly incoming call that circulates takies the problem of loop trunks equipment again.

The above has been described in detail the method for quick refusal loop trunks blacklist provided by the present invention incoming call.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention it being done all will consist of infringement of patent right of the present invention, will bear corresponding legal liabilities.
