Embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
Provided by the present inventionly realize that the professional device that recovers automatically comprises: the port status reading unit of Xiang Lianing, detecting unit and port controlling unit successively; Wherein, the port status reading unit is used to read the state of activation and the synchronous regime of its local side principal and subordinate port that connects; Detecting unit, be used to obtain the state of activation and the synchronous regime of the local side principal and subordinate port that the port status reading unit read, and be used to the deexcitation of local side principal and subordinate port, the activation manipulation that recover professional according to the state of activation of obtaining and synchronous regime control port control unit; The port controlling unit then is used for carrying out the deexcitation of local side principal and subordinate port, activation manipulation according to the control of detecting unit.
Provided by the present inventionly realize the professional method of recovering automatically, need read the state of activation and the synchronous regime of local side principal and subordinate port, and be used to the deexcitation of local side principal and subordinate port, the activation manipulation that recover professional according to the state of activation that reads and synchronous regime.
Referring to Fig. 2, Fig. 2 is the professional installation drawing that recovers automatically of the realized SHDSL of a preferred embodiment of the present invention, and this device comprises port status reading unit 210, detecting unit 220 and the port controlling unit 230 that links to each other successively; And port status reading unit 210 also links to each other from port with the local side master port, the local side that are positioned at the local side side respectively.As logic entity, port status reading unit 210, detecting unit 220, port controlling unit 230 can be arranged in the same physical entity, or be arranged in three different physical entities; Certainly, also wherein certain two can be arranged in the same physical entity.
During practical application, port status reading unit 210 can be used prior art and read its local side master port that connects and local side state of activation and the synchronous regime from port; And, obtain to detecting unit 220 real-times local side master port that port status reading unit 210 reads and local side state of activation and synchronous regime from port.Concrete acquisition methods has multiple, as: detecting unit 220 is to port status reading unit 210 transmit port status inquiry command, and local side master port that when port status reading unit 210 is received this order self is read and local side send to detecting unit 220 from the state of activation and the synchronous regime of port; Perhaps, local side master ports that directly self read by port status reading unit 210 and local side report detecting unit 220 from the state of activation and the synchronous regime of port.
Certainly, describedly obtain operation and also can periodically carry out.
When detecting unit 220 obtains local side master port and local side from the state of activation of port and synchronous regime from port status reading unit 210, judge according to the port status that obtains whether local side principal and subordinate port all is in state of activation and is in synchronous regime, if, 220 of detecting units immediately or obtain local side master port and local side state of activation and the synchronous regime from port once more from port status reading unit 210 after waiting for a period of time and judge according to the port status that obtains whether local side principal and subordinate port all is in state of activation and is in synchronous regime ...; Otherwise, detecting unit 220 sends deexcitation local side master port orders and deexcitation local side from port command to port controlling unit 230, when detecting unit 220 sends deexcitation order at certain port or afterwards, also at this port to port controlling unit 230 transmit port activation commands, that is: detecting unit 220 also sends the order of activation local side master port to port controlling unit 230 when port controlling unit 230 sends the order of deexcitation local side master port or afterwards, and also 230 transmissions activate local side from port command to detecting unit 220 to the port controlling unit when port controlling unit 230 sends the deexcitation local sides from port command or afterwards.
Can will comprise the order of above-mentioned deexcitation local side master port, deexcitation local side from port command and activate the order of local side master port, activate local side and be referred to as the port operation order from the order that is used to recover professional of port command.
In actual applications, timer can also be set in detecting unit in advance, and determine that at detecting unit 220 local side principal and subordinate port starts this timer when all not being in state of activation as yet or not being in synchronous regime; This timer is notified detecting unit 220 to send modes such as message when overtime, detecting unit 220 judges once more when knowing timer expiry whether local side principal and subordinate port all is in state of activation and is in synchronous regime, if, 220 of detecting units immediately or obtain local side master port and local side state of activation and the synchronous regime from port once more from port status reading unit 210 after waiting for a period of time and judge according to the port status that obtains whether local side principal and subordinate port all is in state of activation and is in synchronous regime ...; Otherwise 220 of detecting units send described port operation order to port controlling unit 230.
By the above as seen, deexcitation local side master port order from detecting unit 220 can be received in port controlling unit 230, the deexcitation local side is from port command and activate the order of local side master port, activate local side from port command.
When receiving the order of deexcitation local side master port, prior art is used with the deexcitation of local side master port in port controlling unit 230, and concrete operations are generally: the communications status attribute of local side master port is set to deactivation status; When receiving the deexcitation local side from port command, from the port deexcitation, concrete operations are generally: local side is set to deactivation status from the communications status attribute of port to port controlling unit 230 application prior aries with local side.
When receiving the order of activation local side master port, port controlling unit 230 is used prior art the local side master port is activated, concrete operations are generally: port controlling unit 230 carries out the activation of shaking hands, training from comprising of port at local side master port, Modem side by local side master port, the central processing unit (CPU) of Modem side from port and Modem that links to each other, and makes local side master port and Modem side finally be in state of activation from port.When receiving the activation local side from port command, port controlling unit 230 use prior aries with local side from port activation, concrete operations are generally: port controlling unit 230 is undertaken at the comprise activation of shaking hands, training of local side from port, Modem side master port by the CPU of local side from port, Modem side master port and Modem that links to each other, and makes local side finally be in state of activation from port and Modem side master port.
Certainly, in carrying out above-mentioned process with local side principal and subordinate port activation, port controlling unit 230 also needs to use prior art and is provided for guaranteeing the synchronous configuration information of local side principal and subordinate port frame, this configuration information can be added in the frame that the follow-up quilt that is sent split to guarantee local side principal and subordinate port; When making the frame that Modem receives that the quilt from local side principal and subordinate port splits, can reconfigure according to the frame that the configuration information that is comprised in the frame will be split, so that the frame that combines is sent to continuous user side equipment.
In fact, no matter whether be provided with described timer, detecting unit 220 can send described port operation order at the synchronization or the different moment.When sending described port operation order constantly in difference, detecting unit 220 at first sends the order of deexcitation local side master port usually, sends the deexcitation local side again from port command; After this, can detecting unit 220 be waited for a period of time, send by detecting unit 220 then and activate the order of local side master port, send again afterwards and activate local side from port command by modes such as timer are set.
Why sending the order of activation local side master port to port controlling unit 230, activating local side will wait for a period of time before port command, be because port controlling unit 230 is being received from the deexcitation local side master port order of detecting unit 220 and deexcitation local side after port command, expending some times is used to carry out corresponding local side master port deactivating operation and local side from the port deactivating operation, if in this deactivating operation process, send the order of activation local side master port to port controlling unit 230, activate local side from port command, 230 of port controlling unit might cause deexcitation or activation manipulation failure because of receiving too much order at short notice.Therefore, preferably before port command, waiting for a period of time, with the deactivating operation that guarantees that port controlling unit 230 can during this period of time be finished at local side principal and subordinate port to the 230 transmission activation local side master port orders of port controlling unit, activation local side.
As seen from Figure 2, if what local side provided is professional not normal, so after finishing described local side principal and subordinate port deactivating operation and local side principal and subordinate port activation operation, Modem can normally receive, make up the frame from local side, and the frame of finishing combination can be sent to the user side equipment that links to each other with Modem; Therefore, use the user of this user side equipment just can accept business naturally from local side, that is: the device of being made up of port status reading unit 210, detecting unit 220 and port controlling unit 230 can guarantee that local side can recover this business when professional not normal automatically in that it provided.This obviously helps local side normally for the user provides professional, thereby can increase substantially user satisfaction.
If the operation that device shown in Figure 2 can be carried out is represented with flow process, then as shown in Figure 3.Fig. 3 is the professional flow chart that recovers automatically of the realized SHDSL of a preferred embodiment of the present invention, and this flow process mainly may further comprise the steps:
Step 310: the activation, the synchronous regime that detect local side principal and subordinate port.
Step 320: judge according to activation, the synchronous regime of detected local side principal and subordinate port whether local side principal and subordinate port all is in state of activation and is in synchronous regime, if, process ends or return step 310 then; Otherwise, enter step 330.
In actual applications, when local side principal and subordinate port all is in unactivated state, also can process ends or return step 310.
Step 330: deexcitation local side principal and subordinate port, and activate local side principal and subordinate port once more.To concrete port activate, during deactivating operation according to time sequencing can be with reference to the corresponding description among Fig. 2.
In fact, described in Fig. 2, Fig. 3 to concrete port activate, during deactivating operation according to time sequencing, be to realize, and this state machine software is arranged in the detecting unit usually by state machine software commonly used at present is set.
Particularly, the operation relevant with time sequencing that can realize of described state machine software as shown in Figure 4; More precisely, Fig. 4 is the schematic diagram that state machine software control detecting unit is realized the operating state conversion.Below, the function that the angle of changing from the detecting unit operating state can realize state machine software is described.
Among Fig. 4, detecting unit at first can be in initial condition, and judges whether local side principal and subordinate port all is in state of activation.When definite local side principal and subordinate port all was in state of activation, detecting unit can remain on initial condition; Whether when having only a port to be in state of activation in definite local side principal and subordinate port, detecting unit then is transformed into state A, timer and Rule of judgment X are set satisfy.Described condition X is: local side principal and subordinate port all is in state of activation and is in synchronous regime.
In general, when condition Y satisfied, detecting unit can remain on initial condition usually.Described condition Y is: present state of activation of local side principal and subordinate port or unactivated state are identical.
When being in state A, when the counting of timer during less than N, detecting unit remains on state A; Certainly, if at this moment detecting unit determines that condition X is satisfied, then returns to initial condition.When the counting of timer arrived N, whether detecting unit Rule of judgment X satisfied, if satisfy, detecting unit then returns to initial condition; Otherwise detecting unit is transformed into state B.
When being in state B, whether detecting unit Rule of judgment X satisfies, if satisfy, detecting unit then returns to initial condition; Otherwise detecting unit sends the order of described deexcitation local side master port, is carried out with the operation that guarantees deexcitation local side master port, and is transformed into state C.
When being in state C, detecting unit sends described deexcitation local side from port command, is carried out from the operation of port with assurance deexcitation local side, and is transformed into state D.
When being in state D, timer is set; When the counting of timer during less than M, detecting unit remains on state D; When the counting of timer arrived M, detecting unit sent the order of described activation local side master port, was carried out with the operation that guarantees activation local side master port, and was transformed into state E.
When being in state E, detecting unit sends described activation local side from port command, activates local side with assurance and is carried out from the operation of port, and be transformed into initial condition.
So far, state machine software has been finished with regard to the control detection unit and can have been made the professional whole process of recovering automatically of SHDSL.
The effect that described state D is set is: waited for a period of time before port command at the order of the described activation local side master port of transmission, activation local side, during this period of time can finish smoothly at the deactivating operation of local side principal and subordinate port with assurance.Have, the timer described in state A and state D can be same timer again, also can be two different timers.Have again, above-mentioned M, N be respectively can be identical or different time span.
Need to prove that the present invention not only is confined to the SHDSL technical field; In DSL in addition outside other technical field in, at other communication technology like the SHDSL technology type, also can use apparatus of the present invention and method.
By the above as can be seen, provided by the present inventionly realize the professional apparatus and method of recovering automatically, guarantee that all local side can recover this business when professional not normal automatically in that it provided; This obviously helps local side normally for the user provides professional, thereby can increase substantially user satisfaction.
