Abstract
The present invention discloses a method for implementing exception wildcard. The method comprises that: commands which at least comprise a specific domain, an exceptional wildcard character and exceptional member identification parameters are issued; the commands are analyzed, and the exceptional wildcard character in the commands is explained; each member identification of the specific domain is respectively compared with exceptional member identification according to the definition of the exceptional wildcard character; the operation corresponding to the commands is carried out to member whose member identification is different from the exceptional member identification.
Description
Technical field
The wildcard technology that the present invention relates to identify in the communication network, particularly a kind of implementation method of exception wildcard.
Background technology
In the most standard agreement of definition at present, all use the wildcard of sign, as in MGCP (MGCP agreement), end points (Endpoint) identifies and is connected (Connection) sign, the asterisk wildcard " * " of Endpoint ID definition is represented all end points, asterisk wildcard " $ " is represented end points arbitrarily, the asterisk wildcard " * " of connection identifier definition is represented all connections, the connection that asterisk wildcard " $ " expression is current.When the last all end points faults of media gateway (MG), MG just can use end points asterisk wildcard " * " so, reports fault order of MGC.And do not need each Endpoint ID to report a fault order.Thereby reduced message a large amount of between MGC and the MG, greatly improved the treatment effeciency of equipment.For example sign of the context (Context) in the H248 agreement and terminal (Termination) sign again, the asterisk wildcard " * " of Context identifier definition is represented all contexts, the asterisk wildcard " * " that terminal iidentification defines is represented all terminals.When MGC wishes that terminals all in the context is all listened to the music, just can specify a Context identifier, use the asterisk wildcard " * " of terminal then, issue the order of listening to the music and give MG, do not give MG and do not need to issue an order of listening to the music to each terminal in this Context identifier of appointment.Thereby reduced interacting messages a large amount of between MGC and the MG, reduced the load of transmission network between MGC and the MG.Generally speaking Biao Shi wildcard can reduce the load of transmission of messages network, improves the efficient of command process simultaneously, strengthens the function of command process.
Use an order that all members are carried out operation of the same type though can adopt the wildcard method in the prior art, but when will other members except that some or certain several member be operated (i.e. exception operation), then can only send the identical order of order to each member.As: in the present meeting, the participant of a conference convening person and many meetings is arranged, the caller of meeting now requires to put the music on to each participant except that own.Send an identical order of listening to the music for so each participant except that the conference convening person.Therefore, when realizing the exception operation in the prior art, not only complex operation, process of commands efficient are low, and issue a large amount of operational orders the transmission network load of protocol command message is increased the weight of.
Summary of the invention
The object of the present invention is to provide a kind of implementation method of exception wildcard, when realizing that exception is got rid of operation in the prior art, because of operating the problem that there is complex operation in member's transmitting order to lower levels and strengthens the transmission network load to each to solve.
The invention provides following technical scheme:
A kind of implementation method of exception wildcard is used for other members except that the exception member in the specified domain are operated, and the method comprising the steps of:
Send the order that comprises specified domain, exception wildcard symbol and exception member identification parameter at least;
Analyze the exception wildcard symbol in described order and the interpreted command; And
Described order receives the definition of object by this exception wildcard symbol, and each member's sign with described specified domain compares with exception member sign respectively, and member's sign is identified member inequality with described exception member carries out the described corresponding operation of ordering.
According to technique scheme:
Described exception member sign can be one or more.
Described order is to be handed down to media gateway by Media Gateway Controller.
Described order can be to give Media Gateway Controller by medium gateway to report.
The member is designated end points (Endpoint) sign, connection (Connection) sign or request event (RequestEvent) sign in the MGCP (MGCP agreement).
The member is designated context (Context) sign, terminal (Termination) sign or incident (Event) sign in the H248 agreement.
The member is designated end points (Endpoint) sign in based on network call signaling (NCS) agreement, connects (Connection) sign and request event (RequestEvent) sign.
Described exception wildcard symbol for "! " symbol.
Adopt the present invention, can the part member in a certain territory be operated accordingly by issuing a subcommand, and do not need each member's difference transmitting order to lower levels among this part member, thereby can significantly reduce the message-length of protocol command, reduce the load of transmission network, also make simple to operate simultaneously.
Description of drawings
The networking schematic diagram of Fig. 1 for implementing;
Fig. 2 is a flow chart of the present invention.
Embodiment
The present invention defines exception wildcard sign, and this label table is shown in the specified domain (scope) except that a certain sign or all signs of some sign, uses by the exception wildcard sign being made the parameter that operation orders, to simplify the operation.
In the present embodiment, exception wildcard symbol for "! ", signs all except that the sign of its back is represented with identifier in its back.
Method of the present invention is: send the order that comprises specified domain, exception wildcard symbol and exception member identification parameter at least; The exception wildcard that is received in described order of object analysis and the interpreted command by order accords with; And by the definition of this exception wildcard symbol, each member's sign with described specified domain compares with exception member sign respectively, and member's sign is identified member inequality with described exception member carries out the described corresponding operation of ordering.
To carry out meeting in network is that example is elaborated to invention:
Consult shown in Figure 1ly, Media Gateway Controller is connected with a plurality of media gateway, and media gateway is connected with a plurality of subscriber terminal equipments (for example phone etc.).What move on the media gateway can be MGCP agreement, H248 agreement, NCS agreement etc.
When Media Gateway Controller is realized a Conference Calling, to conferencing resource of media gateway application.When media gateway receives the order of application conferencing resource of Media Gateway Controller, distribute the conferencing resource of a free time, return to Media Gateway Controller for simultaneously sign of this conferencing resource.Media Gateway Controller uses this sign that conferencing resource is operated later on.The Media Gateway Controller transmitting order to lower levels requires the caller of meeting is joined in this meeting (meeting identification that uses media gateway to distribute) to media gateway, media gateway joins first conference member in the meeting, and distribute a sign to return to Media Gateway Controller for this conference member, make things convenient for Media Gateway Controller that this conference member is operated.Media Gateway Controller one by one transmitting order to lower levels is then given media gateway, the participant of meeting is joined (meeting identification that uses media gateway to distribute) in this meeting, media gateway joins each conference member in the meeting, and distribute an identifier to return to Media Gateway Controller for each conference member, make things convenient for Media Gateway Controller that this conference member is operated.
The conference convening person is the user terminal with special authority, and the meeting participant is the user terminal of general authority.Concerning media gateway, it distributes a sign for each conference member, does not distinguish the caller of meeting or the participant of meeting.
Consult Fig. 2, adopt the exception wildcard symbol, it is as follows to the implementation procedure that the participant of each meeting puts the music on to send order request by the caller of meeting:
Step 10: the conference convening person sends order and puts the music on to the participant of meeting, does not wherein comprise caller itself.
The caller can use exception wildcard symbol "! " the back sign of distributing for the conference convening person with media gateway is as command parameter, sends an order request except that the conference convening person, members all in the meeting listen to the music; Perhaps the caller is by triggering specific customer incident as order.
Step 20: Media Gateway Controller issue comprise exception wildcard symbol "! " order give media gateway, require to give the playback of meeting members that removes the conference convening person happy.
Media gateway reports Media Gateway Controller with caller's order or customer incident.If what report is customer incident, then by Media Gateway Controller produce the band asterisk wildcard "! " and the order of caller sign.Simultaneously, also comprise meeting identification (domain identifier is promptly ordered at the member in this territory) in the order.
Step 30: the media gateway interpreted command, the meeting participant is put the music on.
Media gateway is by meeting identification, and what can determine the Media Gateway Controller operation is that meeting.Find that when reading the conference member identifier asterisk wildcard is arranged "! ", media gateway just travels through each conference member in this meeting, if find itself and asterisk wildcard "! " after the conference member sign followed unequal, just carry out the operation of on this conference member, putting the music on.Thereby put the music on for the participant of each meeting, need not the caller of meeting is put the music on.
Certainly, also can report the order that comprises exception wildcard symbol and exception member sign to Media Gateway Controller, explain and carry out corresponding operating by Media Gateway Controller by media gateway.
On MGCP agreement, H248 agreement and NCS agreement or other agreements, all can realize wildcard as stated above, as:
In the MGCP agreement, can connect (Connection) sign, and request event (RequestEvent) sign is carried out such wildcard definition to end points (Endpoint) sign.
When using the MGCP agreement to represent to report except that Endpoint ID 2-5, all end points all drop into service command and are:
RSIP?120！aaln/[2-5]@domain.com?mgcp?1.0
RM：restart
So when use the MGCP agreement represent on the conferencing endpoints except that a connection identifier 1 orders of all connection playbacks be:
RQNT?1201aaln/1@rgw-2567.whatever.net?MGCP?1.0
X：0123456789AC
S：bau/pa(an＝1)@！1
When the order of using the MGCP agreement to represent to monitor an end points to reach the standard grade in the bag (Line Package) except that the incident of off-hook (hu) be so:
RQNT?1201aaln/1@rgw-2567.whatever.net?MGCP?1.0
X：0123456789AC
R：L/！hu
Can be in the H248 agreement to context (Context) sign and terminal (Termination) sign, incident (Event) sign and stream (Stream) sign are carried out such wildcard definition.
When using the H248 agreement to represent to report except that terminal iidentification 1, all end points all drop into service command and are:
MEGACO/1[124.124.124.222]
Transaction＝9998{
Context＝-{
ServiceChange＝！A1{Services{
Method＝Restart，
ServiceChangeAddress＝55555，Profile＝ResGW/1}
}
}
}
Be all contexts of 5000 when using the H248 agreement to represent to delete a gateway to remove Context identifier so:
MEGACO/1[123.123.123.4]：55555
Transaction＝50009{
Context＝！5000{
Subtract＝*{}
}
}
Represent to monitor that when using the H248 agreement order that removes the incident of off-hook (of) in the artificial line bag on the end points (Analog Line SupervisionPackage) is:
MEGACO/1[123.123.123.4]：55555
Transaction＝50006{
Context＝5000{
Modify＝A5555{
Events＝1235{al/！of}
}
}
}
In the NCS agreement, can connect (Connection) sign, and request event (RequestEvent) sign is carried out such wildcard definition to end points (Endpoint) sign.
When using the NCS agreement to represent to report except that Endpoint ID 2-5, all end points all drop into service command and are:
RSIP?120！aaln/[2-5]@domain.com?mgcp?1.0
RM：restart
All orders that connect playbacks are except that a connection identifier 1 on use NCS agreement is represented to a conferencing endpoints:
RQNT?1201aaln/1@rgw-2567.whatever.net?MGCP?1.0
X：0123456789AC
S：bau/pa(an＝1)@！1
When the order of using the NCS agreement to represent to monitor an end points to reach the standard grade in the bag (Line Package) except that the incident of off-hook (hu) is:
RQNT?1201aaln/1@rgw-2567.whatever.net?MGCP?1.0
X：0123456789AC
R：L/！hu
For use the exception wildcard symbol in other system, its principle is same as described above.
