Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
Video conferencing system of the present invention as shown in Figure 2.Its main points are:
Whole frequency conference system is divided into Management Layer, operation Access Layer, three levels of user side.Connect by public network (backbone network) between Management Layer and the Access Layer.Access Layer directly is connected by user's local area network (LAN) with user side.
Management Layer is divided into a plurality of operating areas according to geographical position and other factors, and there is independently operating area sign each operating area, is similar to the area code notion in the telephone network.Provide necessary service support by standard agreement or from protocols having between the operating area, as directory service.Among Fig. 4 example two operating areas, operating area sign is exemplified as 81 and 82.The operating area division that can have levels is such as the subordinate operating area that is subordinated to 81 operating areas can be set.
Each operating area comprises two service units at least: management and directory service unit; Multiple spot service and Exchange Service unit.Management and directory service unit are used to provide services such as user management, rights management, authentication management, charging, account, ticket, resource management and scheduling.Multiple spot service and Exchange Service unit are used to provide services such as multi-point support, media data exchange.
The operation Access Layer is made up of the access point that is distributed in the whole network edge.Each access point comprises 1 or many access devices.Each access device is subordinated to a unique operating area.Each access device distributes one or more in the unique access code in the operating area of subordinate (described operating area Number for access).The management of management and directory service group in the operating area under access device is accepted, and in directory service, register access code.Among Fig. 4 example two access points, in each access point example 1 access device.Access device in the access point 1 is subordinated to 81 operating areas, and the number of distribution is 1000.Access device in the access point 2 is subordinated to 82 operating areas, and the number of distribution is 1001.
Under special circumstances, access point can not comprise access device, and directly replaces with ustomer premises access equipment.
Also should possess a streamlining management and directory service module between access device and the user side, this module can be positioned at access device inside, also can be the self-contained unit (software module or autonomous device) in user's local area network (LAN).Access device also should distribute the access code (described user's Number for access) of a unique inside, and this number can be set by operator, also can be set up on their own by the user.This inside access code is registered in streamlining management and directory service module and unique existence.Among Fig. 4 example the inside access code of the access device in the access point 1 be 9, the inside access code of the access device in the access point 2 is 0.
Access device can directly be connected with 1 ustomer premises access equipment, also can connect many ustomer premises access equipments (comprising terminal, gateway, multiple spot server etc.) by network.
Each ustomer premises access equipment distributes one or more Subscriber Numbers, and this number is registration and unique existence in management of simplifying and directory service module.This number can be distributed by operator, also can be distributed voluntarily by the user.Among Fig. 4 example a plurality of Subscriber Numbers, be respectively 801,802,200,6001,6002,3000, wherein 801,802,200 be registered in the streamlining management and directory service module of access device of access point 1 subordinate, 6001,6002,3000 are registered in the streamlining management and directory service module of access device of access point 2 subordinates.
Management described in the present invention and directory service group (containing streamlining management and directory service module) include but not limited to technology such as gateway, all kinds of directory services and product in the prior art.
Technology and products such as H.323MCU the multiple spot service described in the present invention, Exchange Service include but not limited in the prior art, SIP MCU.
The process of registration described in the present invention and assignment numbers, agreement and technology realize that the process such as RAS signaling, SIP signaling in the prior art that includes but not limited to, agreement and technology realize.
Gateway of the prior art and multiple spot server just can be formed an operating area of simplifying most.
As shown in Figure 3, access device can be a hardware device independently, also can be software module independently.The logic of access device and the main points of functional module are:
Access device has two independently network addresss.One is distributed by operator, and access device uses this address and affiliated operating area to carry out network to be connected and to communicate by letter.Assist to be specified by operator or distributed voluntarily by the user for one, access device uses this address and user side to carry out network to be connected and to communicate by letter.We represent with two network interfaces in Fig. 3, and when specific implementation, physical interface can be one or more interfaces.Under specific circumstances, just directly use public network address as user's internal network, just because security reason is divided into internal-external network, access device also can have only a network address.
Access device has two independently access codes.One is distributed by operator, registration and keep unique in the management of affiliated operating area and directory service group.One assist to be distributed by operator or is distributed voluntarily by the user, registration and keep unique in streamlining management and directory service module.These two access codes are registered as operating area and inner LIST SERVER respectively by directory service module in the internal logic module among Fig. 3 and the directory service module in the external logic module respectively.
Calling can be accepted or send to access device.Initiation and receipt of call are finished by calling, control module.Call out initiate, refuse, consult, set up, converse, hang up etc. method and process include but not limited to ITU-T in the prior art H.323, the method and the process that define in the standards such as SIP, MGCP.Calling, control module are responsible for the maintenance call tabulation, and control directory service module and the work of media services module cooperative.When service needed (as carry out between the different agreement conversion), call out, control module also is responsible for calling out, the conversion of control protocol.Call signaling and control signaling are carried out bridge joint and forwarding by bridge joint, forwarding module.In order to improve system effectiveness, call out and control signaling and can between two modules, directly transmit according to the control command of bridge joint, forwarding module.
Medium process module is responsible for that media data (audio frequency, video, data etc.) is carried out sending and receiving and is handled, when service needed (as carry out between the different coding algorithm conversion), medium process module also be responsible for to medium decode, handle, operation such as coding.Carry out the bridge joint and the forwarding of media data between the medium process module by bridge joint, forwarding module.In order to improve system effectiveness, media data can directly be transmitted between two modules according to the control command of bridge joint, forwarding module.
Access device carries out bridge joint and transfer by bridge joint, forwarding module to call command and media data, and its situation that may occur has 3 kinds:
The user side of the multiple spot service of operating area, Exchange Service group calls in several access device inside (inside refers to an access device to user side one side), access device is accepted this calling, and sends calling to the ustomer premises access equipment of inside.After two callings are all set up, the control signaling of access device bridge joint and two callings of transfer, media data etc.
Access device internal user end is called out access device outside (outside refer to an access device to the operating area one side) multiple spot service or user side, and access device is accepted this calling, and sends calling to the operating area.After two callings are all set up, the control signaling of access device bridge joint and two callings of transfer, media data etc.
Access device sends calling to inner user side and outside operating area simultaneously.After two callings are all set up, the control signaling of access device bridge joint and two callings of transfer, media data etc.
Safeguard in bridge joint, the forwarding module and transmit, each that transmit all corresponding inside and outside a pair of calling.Bridge joint, forwarding module are according to transmitting processing and the forwarding that controlling call, control module and medium process module are carried out data.
Access device is initiated or call accepted, all must accept management and directory service group and management such as streamlining management and directory service module in the operating area simultaneously, and obtains necessary call information from the two.
Bridge joint and method for transfer include but not limited to agent skill group in the prior art, the Q.931 route pattern that H.323 bridging technology, ITU-T define in the standard, route pattern H.245, correlation technique that defines in SIP, the MGCP standard and method etc.
The communication means of the control command between each system module can adopt semaphore in the prior art, synchronously, several different methods such as incident, interprocess communication.
In order better to describe the whole system operation principle, the example of 2 concrete communication processes is described below, these 2 examples all are described in existing ITU-T and H.32 how use the native system model in 3 systems.Example is used the example number of Fig. 3 and middle mark thereof, defines and is illustrated as:
Multiple spot service 700 (MCU1) have been registered among the GK1, access device 1001 (access device 1).
Multiple spot service 600 (MCU2) have been registered among the GK2, access device 1001 (access device 2).
The adjacent each other gateway of GK1 and GK2.
Registered access device 9 (access device 1) among the GK3, user side 801, user side 802, user side 200.
Registered access device 0 (access device 2) among the GK4, user side 6001, user side 6002, user side 3000.
GK1 and GK2 are for calling out route pattern (Q.931 route and H.245 route).
GK3 and GK4 are non-route pattern.
In order to reduce communication delay, GK1 and GK2 also can not use route pattern.
Example one: user side 801 calling parties hold 200.Flow process is:
1) 200 of user side 801 callings is user sides of this local area network (LAN) inside, directly to affiliated GK3 request call 200.
2) GK3 allows to call out.
3) 801 call out 200, connect.
Example two: user side 801 calling parties hold 6002.Flow process is:
1) the whole network call number of user side 6002 is 82-1001-6002.
What 2) user side 801 was called out is the user side of affiliated access device outside, and therefore 801 to GK3 request call 9-82-1001-6002.
3) GK3 searches LOGIN directory, finds 9 to be access device 1, allows to call out.
4) 801 call out 9 (access devices 1).
5) access device 1 call accepted, and to GK1 calling 82-1001-6002.
6) GK1 calls out GK2 (82).
7) GK2 searches LOGIN directory, finds 1001 to be access device 2.GK2 calls out 1001 (access devices 2).
8) access device 2 call accepteds, and to GK4 calling 6002.
9) GK4 searches LOGIN directory, finds user side 6002, allows to call out.
10) access device 2 calls out 6002.
11) connect foundation.
Wherein, specifically connection situation is:
801＜==access device 1＜==GK1＜==GK2＜==access device 2＜==6002.
When GK1 and GK2 do not use route pattern:
801＜==access device 1＜==access device 2＜==6002.
