Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Embodiment one
Referring to Fig. 2, present embodiment provides a kind of method of regulating bandwidth occupied by service, and this method comprises:
101: receive professional bandwidth change request, pre-change bandwidth unit sign is carried in this bandwidth change request;
102: according to this bandwidth change request, the state of the corresponding pre-change bandwidth unit of this pre-change bandwidth unit sign is set, the content that is provided with is sent to Su Duan, and receive the auditing result that this Su Duan returns;

The method of the adjusting bandwidth occupied by service that present embodiment provides is not being decreased under the disconnected professional situation, and the state of bandwidth unit is regulated bandwidth occupied by service in real time through consultation, has strengthened the adaptive capacity to access service, has improved the utilance of service bandwidth.
When regulating bandwidth occupied by service, the state information of bandwidth can at first be introduced two information sets, bandwidth unit state group and the bandwidth unit assign group of embodiment of the invention definition below by the information sets transmission.
The bandwidth unit state group is used for storing the state of each bandwidth unit, and the dynamic change with the mapping situation of business.The basic status of bandwidth unit can be divided three classes, and a class is to use state (Used), represents this bandwidth unit as the carrying subscriber signal, and this bandwidth unit specifically can be filled the subscriber signal type identification; Second class is idle condition (Idle), represents still unallocated bearer service; The 3rd class is a state of a control, is used as the control word of bandwidth application unit or release bandwidth unit, and control word specifically can comprise: subscribe request (Subscribe), release request (Release), agreement (Ok), refusal (Fail) etc.According to actual needs, can also increase control word.
The bandwidth unit assign group, storage user's bandwidth unit binding sign is used for showing which bandwidth unit bundlees in the bandwidth unit state group.A plurality of bandwidth unit passages of some users' the professional possibility of big capacity occupied bandwidth unit state group, we adopt the bandwidth unit assign group to distinguish the major path that a plurality of bandwidth unit passages bindings back forms.Like this, even the subscriber signal type identification of different user occupied bandwidth unit is identical, also can distinguish different users by the bandwidth unit assign group.Particularly, the bandwidth unit of user's correspondence binding sign can be stored in the respective bandwidth unit of bandwidth unit assign group, the bandwidth unit of bandwidth unit identifies identical in the bandwidth unit state group of this respective bandwidth unit and CU.
Further, bandwidth unit in the information sets can time slot or time slot group etc., if time slot (TS, Timeslot), then bandwidth unit state group and bandwidth unit assign group become time slot state group (TSG accordingly, Timeslot Status Group) and time slot allocation group (TDG, Timeslot Distribution Group).Be that time slot is an example with bandwidth unit below, describe the way of realization of two information sets in detail, other bandwidth unit is identical with time slot, repeats no more here.
The time slot state group referring to Fig. 3, specifically can be the matrix of the capable row of n, and n represents number of time slot, time slot state word of every row storage, and this time slot state word length is not limit, and present embodiment is an example with 8 bits.Generally speaking, the n value is fixing, at ITU-T (International Telecommunication Union for Telecommunication StandardizationSector, International Telecommunications Union's telecommunication standards group) among the OPUk/ODUk/OTUk of definition, the n value can be represented the state of 256 time slots at most in.The time slot state group can be carried by the OPUk overhead area, also can be carried by the OPUk payload area.Each time slot can adopt TMD (TimeDivision Multiplex, time division multiplexing) mode, and for example TS1 (Timeslot 1, time slot 1) is positioned at the 17th row, (17+n) row, (17+2n) row ...
Can predesignate the specific value time slot corresponding state of time slot, be example with the time slot state word of 8 bits, referring to table 1.
The tabulation of table 1 time slot state word
As shown in Table 1, only simply list four kinds of state of a control words here,, can suitably increase some state of a control words, do not enumerate one by one here according to the needs of business development.
In addition, in the value of user mode, specifically can store the subscriber signal type identification, referring to table 2, table 2 provides several frequently seen subscriber signal type and value that may be corresponding thereof, for state of a control word and idle condition block branch, the subscriber signal type identification is from 0,000 0000, only otherwise conflict, all can use with state of a control word and idle condition word.
