Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of CM rate assigning method and system.
Background technology
CPRI (Common Protocol Radio Interface) is a kind of general radio interface agreement that is applied in the wireless communication system, is responsible for the crucial internal interface of the wireless base station between definition wireless device controls end (REC) and the wireless device end (RE).The purpose of formulating this standard is to create the opening market towards cellular basestation, thereby reduces for a long time always huge development amount and the expensive cost that accompanies with base station design significantly.
The establishment of CPRI helps the standardization of wireless base station auxiliary products, makes communications equipment manufacturer can selectively buy the wireless base station subsystem, thereby improves product development rate, shortens the new product release time, and guarantees the rich of product.And what directly therefrom benefit is operator, because this standard will improve the efficient of network design.The establishment of CPRI industry cooperative association can concentrate on energy in the research and development of core technology ability base station manufacturer, and can buy the wireless base station subsystem of unified standard.The topmost benefit that this tissue brings is, allows the new technology that is introduced into be able to faster development, and makes base station manufacturer provide abundant more product line for operator, with the shorter time product invested market simultaneously.Simultaneously operator can benefit from also that product is more widely selected, the further raising of solution and network design efficient.The original enterprise of CPRI is devoted to start emulative mobile network's parts industry with of one mind, and by open CPRI interface, whole wireless industry is benefited.CPRI will play supplementary function to existing standardization body (for example 3GPP/3GPP2), and the general-purpose interface of its exploitation will be applied in the wireless base station product of mobile system.
Figure 1 shows that CPRI link structure schematic diagram.
As shown in Figure 1, the CPRI agreement is divided into two part: REC ends and Re end generally.RE is in far-end, and is middle by optical fiber, cable or the connection of other signal transmission mediums.Data flow among the figure comprises two class data of chain of command and data surface.
Figure 2 shows that CPRI agreement working state schematic representation.
As shown in Figure 2, the CPRI agreement is in work, and being divided into is 7 states, is respectively:
0 state (Standby) is an idle condition.In this state, agreement waits for that the upper strata instruction starts the CPRI protocol state machine.
1 state (synchronization) is the line speed negotiation state, also is synchronous regime.In this state, the CPRI agreement is carried out the line speed negotiation according to the line speed negotiation mechanism of agreement regulation, and the physical circuit transmitting-receiving speed that requirement reaches REC and RE is consistent.
2 states (Protocol setup) are the protocol version negotiation state.In this state, require the current protocol version of CPRI of agreement two ends REC and RE to be consistent.
3 states (CM plane (L2+) setup) are CM rate consulation states.In this state, the transmitting-receiving speed that requires the high-level data of REC and RE to connect road control (HDLC) reaches consistent, just the data rate unanimity of chain of command.
4 states (Interface and vendor specific negotiation) are normal operating conditionss, and all parameters at expression REC and RE two ends are all consistent, can carry out normal data transfer.Be exactly at this state,, just require to use the CM speed of appointment if find to have the CM speed of appointment.
5 states (Operation) are the same with 4 states, also belong to normal operating conditions.Controlled by upper layer software (applications).
6 states (Passive Iink) are bypass condition.In this state, do not transmit the HDLC data.
The CPRI interface will carry the data (HDLC) of data surface and upper strata chain of command simultaneously.For the correctness that guarantees that the HDLC data send, receive, guarantee that the consistency of HDLC transmitting-receiving speed is very important, at the CPRI protocol layer, guarantee that the speed that HDLC as one man sends, receives is called CM speed.
CM speed is the automatic negotiation method of general employing when the CPRI both link ends mates, but agreement regulation, how much CM speed of no matter consulting is, (described four kinds of states respectively are a stage of CPRI agreement work at the four condition of CPRI agreement, expression link state representation working properly), if find to have the speed of appointment, the speed that agreement will be used appointment transmits the HDLC data.
Directly there is a risk in the method for application protocol assigned rate at present.In case upper layer software (applications) has been specified CM speed exactly,, be easy to cause the HDLC link to break if improper REC and the RE speed of causing of appointed method is inconsistent.Because the far-end of CPRI generally is a unmanned maintenance, may cause upper-layer protocol to open circuit forever so again, cause system crash.Guarantee the reliability of assigned rate, what just become is very necessary.

Embodiment
Core of the present invention is that the wireless device controls end is by carrying out local CM rate consulation and specifying the CM speed that supported by the wireless device end for self alternately with the rate information of wireless device; The wireless device end carries out local CM rate consulation, and for self specifies and the identical CM speed of wireless device controls end CM speed, realization wireless device controls end is worked under identical CM speed with the wireless device end.
Say that more specifically the present invention at first needs to enter system's normal operating conditions, carry out described CM speed then and specify.
System enters before the normal operating conditions process and has started working for being powered on by system to system and enter normal operating conditions, and it comprises:
Start working when system powers on, the CPRI agreement is in idle condition at this moment, and the agreement that is in idle condition waits for that upper-layer protocol sends the instruction that starts the CPRI protocol state machine.
The CPRI agreement is received after the CPRI agreement starting command from upper-layer protocol, entry-line rate consulation state.In this state, the CPRI agreement is carried out the line speed negotiation according to the line speed negotiation mechanism of agreement regulation, makes the physical circuit transmitting-receiving speed of REC and RE consistent.
After the physical circuit rate consulation success of REC and RE, the CPRI agreement enters the protocol version negotiation phase, and negotiation data transmits the version number of employed CPRI agreement, determines to use the CPRI agreement of identical version to carry out transfer of data.
By the negotiation of version number, realize that the CPRI protocol version of REC and the current use of RE is consistent, this moment, CPRI entered CM rate consulation state.After the success of CM rate consulation, CPRI enters normal operating conditions, brings into use the CPRI agreement to carry out transfer of data.
After system enters normal operating conditions, just can carry out CM speed and specify, its designation method is as follows:
REC side upper layer software (applications) sends CM speed to the RE side and specifies prompting message, carries the CM speed of desire appointment in this message;
Specify prompting message when RE side upper layer software (applications) receives CM speed, RE is edge-on promptly to REC side passback acknowledge message, carries the CM speed of desire appointment in the acknowledge message;
After the REC upper layer software (applications) received that desire appointment CM speed in acknowledge message and the definite acknowledge message and the desire that self sends specify CM speed consistent, the REC upper layer software (applications) specified CM speed to be appointed as the CM speed of REC this desire;
After upper layer software (applications) sent the appointment prompting message, the REC through-rate consulted to realize the appointment of CM speed;
After the REC side was specified the success of CM speed, REC sent to RE with this CM speed;
RE receives after the new CM speed that discovery and the current CM speed of self using do not match, and enter CM rate consulation state, carry out the CM rate consulation;
Therefore the upper layer software (applications) of RE finds that RE and CPRI link enter CM rate consulation state, just are appointed as REC side CM speed the CM speed of RE side;
RE passes to REC to the CM speed of new configuration, and whether be used for checking R E identical with the CM speed of REC;
The CPRI both link ends is all worked under new assigned rate, and CM speed is specified successfully, and informs the upper layer software (applications) of REC and RE, the system restoration normal operating conditions.
Below in conjunction with the specific embodiment of the invention accompanying drawing the present invention is elaborated.
Figure 3 shows that the embodiment of the invention one CPRI enters the schematic flow sheet of normal operating conditions.
Step 31, power on when starting working in system, the CPRI agreement is in idle condition, and agreement waits for that the upper strata instruction starts the CPRI protocol state machine.At this moment, upper layer software (applications) should be configured to CM rate consulation state with REC and RE, can not be configured to designated state.
Step 32, after the CPRI agreement is received the upper strata starting command, entry-line rate consulation state, the CPRI agreement is carried out line speed according to the line speed negotiation mechanism of agreement regulation and is consulted, and makes the physical circuit transmitting-receiving speed of REC and RE consistent.
The process that line speed is consulted comprises: CPRI begins to send the indication of CM speed to RE in the REC side according to agreement, and the CM rate value of this CM speed indication representative should be contained in the set consulting the optional value of CM speed.In the process of rate consulation, the adoptable CM speed of REC and RE may have several situations respectively.
After step 33, line speed were consulted successfully, the CPRI agreement entered protocol version and consults, and consulted CPRI version number.
Step 34, by the negotiation of version number, the employed CPRI protocol version of REC and RE is consistent, this moment make the link of CPRI agreement enter CM rate consulation state.
Need in CM rate consulation process to realize that the HDLC transmitting-receiving speed of REC and RE is consistent;
CM rate consulation process at the middle and upper levels software can not specify CM speed;
The CM speed value that the CM rate consulation obtains should be in the speed set of CM rate consulation.
If consult successfully, CPRI 4 (normal operating conditionss) that get the hang of.
Step 35, enter normal operating conditions as CPRI,, can carry out CM speed assigned operation if system needs.
Figure 4 shows that the embodiment of the invention two CPRI carry out the schematic diagram of CM speed appointment in normal operation.
As shown in Figure 4, described CM speed assignment procedure comprises:
Step 41, in the REC side, CM speed is specified in the upper layer software (applications) master control.
When upper layer software (applications) is wanted assigned rate, for preventing the chain rupture of HDLC link, can not give immediately and adopt the link of CPRI protocol transmission data to assign the appointment prompting message, make REC carry out transfer of data with the CM speed of appointment, but, pick up counting simultaneously by specifying prompting message that assigned rate is handed down to RE by current HDLC link.
Step 42, receive the appointment prompting message when RE side upper layer software (applications), then to REC passback acknowledge message, by acknowledgement frame carried immediately by acknowledge message for RE.
RE is carrying the CM assigned rate that REC sends to RE in this message when sending the passback acknowledge message.
The numerical value that carries CM speed in the described acknowledge message is used to detect the correctness of CM speed, prevents to cause that CM speed changes in the REC appointment prompting message because transmission course is made mistakes, and causes the RE side to receive wrong CM speed; Assurance REC side and RE side are supported same CM speed.
After the RE side receives to specify prompting message, need stamp a label in RE side this locality, mark RE side is about to carry out CM speed and specifies.If unmarked label even RE enters CM rate consulation state, is not the new assigned rate of RE configuration yet, as long as to prevent that RE from entering CM rate consulation state and just pointing the situation generation of deciding CM speed.
Step 43, receive the passback acknowledge message but CM speed and the CM speed that self sends of passback in the acknowledge message is inconsistent, then send to the RE side again and specify prompting message when the REC upper layer software (applications).
Do not receive in the time T that pre-sets (, can adjust) when REC end upper layer software (applications) and the answer message of RE then to resend the appointment prompting message according to different system.
If resend above N time (according to the different system requirement, can adjust), expression upper strata HDLC link is unusual, abandon CM speed and specify, and alarm.
Receive CM speed in acknowledge message and the definite acknowledge message when the REC upper layer software (applications) and with after the CM speed of self sending out pine is consistent, remove timing, upper layer software (applications) is that the REC side is specified CM speed.
Upper layer software (applications) obtains by the CM rate consulation after the appointment of REC side CM speed is entered CM rate consulation state by the REC side.
Step 44, after the CM rate consulation finishes, Z.66.0 or Z.194.0 will confirm that spendable REC side CM rate value passes to RE by (position of the transmission CM speed in the CPRI link).
Step 45, RE side joint receive after the CM speed of the new configuration of REC side that discovery is different with the current CM speed of self using, and therefore also enters CM rate consulation state, carries out the CM rate consulation.
After the upper layer software (applications) of step 46, RE finds that CPRI enters CM rate consulation state, be the CM speed of the new appointment of REC side, specify in CM speed and finish the back and remove CM speed specify labels among the RE the CM rate configuration of RE.
Make mistakes in order to prevent REC or RE internal configurations, after requiring the upper layer software (applications) configuration to finish, value in the retaking of a year or grade RE register again, whether the CM speed that detects actual disposition among the RE is consistent with the CM speed of the interior upper layer software (applications) appointment of RE register, if find inconsistent, then reconfigure RE side CM speed, till the rate configuration unanimity.
Z.66.0 or Z.194.0 step 47, RE side are also passed to REC to the CM speed of the new configuration in this locality by (position of the transmission CM speed in the CPRI link), and whether be used for checking R E side identical with the CM speed of REC side.
Step 48,49, when the RE of CPRI side, REC side are used identical appointment CM speed, the success of CM rate consulation is informed the upper layer software (applications) of RE side, REC side respectively with this result, system enters normal operating conditions.
At some special circumstances that may occur in CM speed assignment procedure, its processing method is as follows:
For RE, if treat the set the inside of the speed of appointment at negotiated speed, CM rate consulation state will finish in very short time, and software might can't be discerned this state.Under the situation that can't discern CM rate consulation state, in fact do not influence the success of link negotiation.The speed of demarcating at the label of RE side this locality and the speed of current operation are consistent, because link is bad, reassigning does not influence system.When REC specified new speed again again, this label will be capped, and Figure 4 shows that the embodiment of the invention two CPRI carry out the schematic diagram of CM speed appointment in normal operation.In order to prevent after assigned rate, because equipment one edge system power down, cause CPRI not work, perhaps other factors cause system reset, Yi Bian cause and be in designated state, Yi Bian be in negotiation state, cause system to open circuit forever, require CPRI entering before the CM rate consulation state, eliminate the designated state of REC or RE voluntarily, change its state into the CM rate consulation.If upper layer software (applications) requires CPRI to be operated in the CM speed of appointment, must make corresponding response according to the variation of CPRI state, i.e. CM speed assignment procedure is carried out in the beginning of step 4 from said process again.
Figure 5 shows that the system schematic of the embodiment of the invention three.
