Description
Technical field
The present invention relates to the technical field of macro base station in the 3-G (Generation Three mobile communication system), relate in particular to the method and apparatus of a kind of adjustment TD-SCDMA power amplifier (TPA, TD-SCDMA Power Amplifier) sign.
Background technology
At present, the macro base station of TD SDMA access (TD-SCDMA) system mainly comprises RNC access unit, control and subsystems such as exchange (SCM) unit, baseband processing unit, serial ports expansion plate (SEB), gps clock unit, radio frequency unit (RFU) and TPA.The SCM plate is a master control borad, and it and RFU, TPA and SEB adopt controller local area network (CAN, Controller Area Network) bus to communicate.
The macro base station of full configuration comprises 1 SCM plate, and 6 RFU and 6 TPA unit are divided into three sectors.The RFU of the RFU of each sector, TPA and other sectors, TPA are independent of each other.In each sector, the relation that sets in advance is satisfied in being connected of RFU and TPA.Connection between each unit as shown in Figure 1.In Fig. 1, in the macro base station of full configuration, be divided into A, B, three sectors of C, sector A comprises radio frequency unit A1 (RFU-A1), radio frequency unit A2 (RFU-A2) and TD-SCDMA power amplifier A1 (TPA-A1), TD-SCDMA power amplifier A2 (TPA-A2), sector B comprises radio frequency unit B1 (RFU-B1), radio frequency unit B2 (RFU-B2) and TD-SCDMA power amplifier B1 (TPA-B1), TD-SCDMA power amplifier B2 (TPA-B2), sector C comprise radio frequency unit C1 (RFU-C1), radio frequency unit C2 (RFU-C2) and TD-SCDMA power amplifier C1 (TPA-C1), TD-SCDMA power amplifier C2 (TPA-C2).
In macro base station, each unit is all as a CAN node, and each CAN intranodal is divided into different fructifications again.At present, adopt this CAN node of SCM plate as host node, other CAN node conduct is from node.The SCM plate must be known residing sector of this fructification and node when carrying out information interaction with certain fructification, therefore, each CAN address of node, promptly CAN ID is pre-specified, referring to table 1.
With system shown in Figure 1 is example, suppose that the SCM plate needs and TPA-B1 in fructification carry out information interaction, the sector that the SCM plate must this fructification place then, i.e. sector B also needs to know the CAN node at this fructification place, i.e. the CAN ID of TPA-B1.The CAN ID of all RFU has been prescribed, and the CAN ID of each TPA also has been prescribed.The CAN ID of each unit can be as shown in table 1.
Table 1
In table 1, receive CAN ID and be the CAN node after powering on, when the employed CAN ID of this node of initialization, SCM send message to the CAN node, the destination address of message will use the reception CAN ID of this CAN node.Sending CAN ID is that the CAN node will fill in every message of this node transmission, and being used to identify this message is that this node sends.
As can be seen from Figure 1, in each sector, each TPA and each RFU have physical connection respectively, like this, when a TPA when SCM sends information, two RFU of this sector can receive this information.By the reception mask of CAN controller is set at RFU, can make RFU can only receive the message that a TPA sends, for example, on RFU-A1, shield TPA-A2, then RFU-A1 can only receive the message of TPA-A1 transmission and shield the message that TPA-A2 sends.Equally, can shield TPA-A1 on RFU-A2, the RFU of other sectors can the rest may be inferred.By the reception mask of TPA is set, can make TPA can only receive the message that a RFU sends, for example, on TPA-A1, shield RFU-A2, then TPA-A1 can only receive the message of RFU-A1 transmission and shield the message that RFU-A2 sends.Equally, can shield RFU-A1 on TPA-A2, the TPA of other sectors can the rest may be inferred.
As can be seen, reception mask by the CAN controller is set and the reception mask of TPA, a RFU can only receive the message that a TPA sends, and a TPA can only receive the message that a RFU sends, thereby makes RFU and TPA have man-to-man corresponding relation.
Because the RFU plate all is inserted on the backboard, and on the backboard toggle switch is arranged,, can finds the transmission CAN ID of this node and receive CAN ID according to these information RFU plate so after the RFU plate is inserted on the backboard, can discern the groove position of this node.But TPA is not inserted on the backboard, and is mounted in outdoor.
The toggle switch of three bits (bit) is set on TPA usually, is used to distinguish six TPA of macro base station.Annexation by this represented TPA of the value of toggle switch is as shown in table 2.
Table 2
| The value of toggle switch | Annexation |
| 0 | The RFU of 10 groove positions, A sector |
| 1 | The RFU of 12 groove positions, A sector |
| 2 | The RFU of 10 groove positions, B sector |
| 3 | The RFU of 12 groove positions, B sector |
| 4 | The RFU of 10 groove positions, C sector |
| 5 | The RFU of 12 groove positions, C sector |
As shown in table 2, when the toggle switch value of certain TPA is 3, should be with the RFU of this TPA and 12 groove positions, B sector, promptly RFU-B2 carries out correspondence.When powering on, this TPA will read the value of setting of the toggle switch of this plate from the CPU of self, and determine the sector at place and the RFU of correspondence according to this value of setting, again according to table 1, know the transmission CAN ID of this node and receive CAN ID, thereby finish the initialization of CAN ID.For example: with the toggle switch value is after 3 TPA is connected to the RFU of 12 groove positions, B sector, when powering on, this TPA is 3 from the value of the toggle switch that self CPU reads, then this TPA thinks that this node is connected to the B sector, corresponding RFU is 12 groove position RFU, then this TPA knows that according to table 1 the reception CAN ID of this node is 0x34F, and sending CAN ID is 0x14F.Then TPA is with this node of 0x34F initialization, and when this TPA and SCM carried out information interaction, it was 0x14F that this TPA sends to the CAN ID that carries in the message of SCM, and SCM to issue CAN ID entrained in the message of this TPA be 0x34F.
Present die casting TPA is that the TPA-A1 of A sector and TPA-A2TPA are put in the TPA shell of a die casting, sets toggle switch, then this die casting TPA is labeled as the TPA of A sector, and the toggle switch value is 0 and 1.Equally, the TPA-B1 of B sector, TPA-B2TPA is put in the TPA shell of a die casting, and the toggle switch value is set to 2 and 3, then, this die casting TPA is labeled as the TPA of B sector.Equally, the TPA-C1 of C sector, TPA-C2 is put among the TPA of a die casting, and it is 4 and 5 that the toggle switch value is set, and then this die casting TPA is labeled as the TPA of C sector.Die casting TPA just is divided into these 3 types of the TPA of the TPA of TPA, B sector of A sector and C sector when dispatching from the factory, the result who does so no longer needs the scene that the toggle switch value has been set, the TPA of corresponding each sector, each sector.
Make die casting TPA by present method, its weak point is:
1, when producing, must produce complete die casting TPA, also necessary binding and packing;
2, when mounted, the die casting TPA of each sector can not exchange, in case error is installed, will cause system normally to move;
3, when safeguarding, need file, safeguard and upgrade 3 types of die casting TPA, thereby increase the management difficulty of document.
Summary of the invention
In view of this, the technical problem that the present invention solves provides a kind of method and apparatus of adjusting die casting TPA sign of discerning, so that 3 types die casting TPA can exchange installation, even die casting TPA is installed in and its not corresponding sector, still can guarantee the proper communication of this die casting TPA and system, the normal operation of assurance system, thus only need one type die casting TPA just can satisfy the needs of base station.

Embodiment
At present, when TPA and SCM carry out information interaction, all carry out transparent transmission by RFU, that is, RFU only transmits mutual information and mutual information is not carried out any processing.In the present invention, in RFU, increased the function that the CAN ID to TPA in this sector judges, whether the CAN ID of TPA has been adjusted according to the judged result decision then.
In the present invention, can only to receive the toggle switch value be the message that 0,2 or 4 TPA sends by the reception mask of CAN controller among the RFU being set, can making the RFU that is installed in groove position 10 in each sector.In like manner, can make the RFU that is installed in groove position 12 in each sector can only receive the toggle switch value is the message that 1,3 or 5 TPA sends.
By the reception mask of TPA is set, can make the toggle switch value is that 0,2 or 4 TPA can only receive the message that the RFU that is installed in groove position 10 of different sectors sends.In like manner, by the reception mask of TPA is set, can make the toggle switch value is that 1,3 or 5 TPA can only receive the message that the RFU that is installed in groove position 12 of different sectors sends.
By above-mentioned setting, can make RFU and TPA all have the corresponding relation of one-to-many
Below, in conjunction with specific embodiments method of the present invention being further described in detail, Fig. 2 is a kind of method flow diagram provided by the present invention.
In step 201, after system powers on, TPA will read the value of setting of the toggle switch of this plate from the CPU of self, and according to definite pairing sector of this value of setting and RFU, basis configuration in advance again, i.e. table 1, know the transmission CAN ID of this node and receive CAN ID.
In step 202, TPA sends message to SCM, and the CAN ID in this message is the transmission CANID that TPA obtains in step 201.
In step 203, RFU receives that described TPA after the message that SCM sends, resolves this message, obtains the transmission CAN ID in this message, and obtains the reception CAN ID of corresponding described TPA.
In step 204, RFU is revised as the transmission CAN ID in this message the transmission CAN ID of its corresponding TPA.
In step 205, the message after RFU will handle sends to SCM.
In step 206, RFU receives that SCM sends to the message of described TPA, the reception CAN ID in this message is revised as the reception CAN ID of described TPA.
In step 207, the message after RFU will handle sends to described TPA.
In said method, when die casting TPA is not installed in correct sector, can be by the RFU in the sector, transmission CAN ID and reception CAN ID to each TPA among this die casting TPA carry out corresponding modification, make among this die casting TPA each TPA can with system's proper communication, make the die casting TPA of different sectors can exchange installation.
More particularly, after system powers on, the RFU of each sector is by the wire jumper of backboard, can know the CAN ID of this node, for example, after the RFU-B1 of B sector read backboard and is provided with, the transmission CAN ID that can know this node was 0x14C, receive CAN ID is 0x34C, and the transmission CAN ID of the TPA of this node correspondence is 0x14E, receive CAN ID is 0x34E.In like manner, after the RFU-B2 of B sector read backboard and is provided with, the transmission CAN ID that can know this node was 0x14D, receive CAN ID is 0x34D, and the transmission CAN ID of the TPA of this node correspondence is 0x14F, receive CAN ID is 0x34F.
Suppose that when actual installation, the die casting TPA of A sector is installed in the B sector, then after powering on, the TPA-A1 among this die casting TPA will be according to the toggle switch value 0 of this node, the transmission CAN ID that obtains this node is 0x10E, and receiving CAN ID is 0x30E.In like manner, the TPA-A2 among this die casting TPA will be according to the toggle switch value 1 of this node, and the transmission CAN ID that obtains this node is 0x10F, and receiving CAN ID is 0x30F.
TPA-A1 will carry it and send CAN ID, i.e. 0x10E when sending message to SCM in this message.
After RFU-B1 receives that TPA-A1 sends to the message of SCM, from this message, resolve and know that the transmission CAN ID of this TPA is 0x10E,, obtain the corresponding CAN of reception ID, be 0x30E then according to table 1.
RFU-B1 is with the transmission CAN ID in this message, and promptly 0x10E is revised as 0x14E, and the message after will handling sends to SCM.When RFU-B1 receives that SCM sends to the message of TPA-A1, the reception CAN ID in this message is revised as 0x30E, the message after will handling again sends to TPA-A1.
When TPA-A2 when SCM sends message, RFU-B2 is identical with RFU-B1 to the processing procedure of this message, no longer repeats here.
As can be seen, when die casting TPA is not installed in correct sector, when each TPA among this die casting TPA when SCM sends message, RFU in the sector can make amendment to the transmission CAN ID of each TPA in this message, and the reception CAN ID that SCM is sent in the message of each TPA also carries out corresponding modification, thereby make among this die casting TPA each TPA can with system's proper communication, make the die casting TPA of different sectors can exchange installation.
For realizing said method, as long as the configurator among the RFU is carried out small change.By change to the program that disposes among the RFU, make RFU receive that TPA is after the message that SCM sends, can resolve this message, obtain the transmission CAN ID of the TPA of this message of transmission, and obtain the corresponding CAN of reception ID, then the transmission CAN ID in this message is revised as the transmission CAN ID of its corresponding TPA.RFU can also be revised as the reception CAN ID in this message the reception CAN ID of described TPA when receiving that SCM sends to the message of described TPA.Because the method that configurator is revised has a lot, just do not introduced one by one here.
In above-mentioned two methods, to the setting of the toggle switch value of two TPA among the same die casting TPA, perhaps be 0,1, perhaps be 2,3, perhaps be 4,5.As can be seen, as long as the toggle switch value of two TPA among the just same die casting TPA is set to an odd number, an even number.For example, the toggle switch value of two TPA in can same die casting TPA is set to 0,3,2,1, or 4,3 or the like, the present invention is to so same being suitable for that be provided with.
By method provided by the invention, only need one type die casting TPA just can satisfy the needs of base station.One type die casting TPA can be installed in all sectors, after powering on, by adjustment to the CAN ID of each TPA among the die casting TPA, make die casting TPA in any one sector can with system's proper communication, system is normally moved.
In the above-described embodiments, by the RFU in the sector, to the transmission CAN ID of each TPA among the die casting TPA with receive CAN ID and carry out corresponding modification, make among this die casting TPA each TPA can with system's proper communication.The present invention also proposes another kind of method, can make each TPA among the die casting TPA adjust the CAN ID of this node, thereby make this die casting TPA still can with system's proper communication, below in conjunction with specific embodiment this method is done further to specify, Fig. 3 is the flow chart of this method.
In step 301, system powers on, and sends the RFU that request (CAN ID Req) message is given its sector, place after the TPA initialization.
In step 302, RFU knows that this sector is connected with die casting TPA after receiving the CAN IDReq message that TPA sends in this sector.
In step 303, RFU with its should be corresponding the transmission CAN ID of TPA return to die casting TPA in this sector.
In step 304, the TPA among the die casting TPA receives the CAN ID that RFU returns, and the transmission CAN ID of this node is revised as the CAN ID that RFU returns, and correspondingly revises the reception CAN ID of this node.
Through above-mentioned information interaction, no matter which sector die casting TPA is installed in, can both make each TPA among this die casting TPA that the CAN ID of this node is adjusted into correct CAN ID, thus make this die casting TPA can with system's proper communication, realize that the die casting TPA of each sector can exchange installation.
More particularly, after system powers on, the RFU of each sector is by the wire jumper of backboard, can know the CAN ID of this node, for example, after the RFU-B1 of B sector read backboard and is provided with, the transmission CAN ID that can know this node was 0x14C, receive CAN ID is 0x34C, and the transmission CAN ID of the TPA of this node correspondence is 0x14E, receive CAN ID is 0x34E.In like manner, after the RFU-B2 of B sector read backboard and is provided with, the transmission CAN ID that can know this node was 0x14D, receive CAN ID is 0x34D, and the transmission CAN ID of the TPA of this node correspondence is 0x14F, receive CAN ID is 0x34F.
Suppose that when actual installation, the die casting TPA of A sector is installed in the B sector, then after powering on, the TPA-A1 among this die casting TPA will be according to the toggle switch value 0 of this node, the transmission CAN ID that obtains this node is 0x10E, and receiving CAN ID is 0x30E.In like manner, the TPA-A2 among this die casting TPA will be according to the toggle switch value 1 of this node, and the transmission CAN ID that obtains this node is 0x10F, and receiving CAN ID is 0x30F.
After TPA-A1 and TPA-A2 obtain the CAN ID of this node, send the RFU of CAN ID Req message respectively to the B sector.
RFU-B1 is known to be connected with die casting TPA in this sector after receiving the CAN ID Req message of TPA-A1 transmission.At this moment, RFU-B1 will send the die casting TPA of 0x14E to the A sector.
After TPA-A1 receives the 0x14E that RFU-B1 sends, the transmission CAN ID of this node is revised as 0x14E, the reception CAN ID of this node correspondingly is revised as 0x34E.
In like manner, RFU-B2 is known to be connected with die casting TPA in this sector after receiving the CAN ID Req message of TPA-A2 transmission.At this moment, RFU-B2 will send the die casting TPA of 0x14F to the A sector.
After TPA-A2 receives the 0x14F that RFU-B2 sends, the transmission CAN ID of this node is revised as 0x14F, the reception CAN ID of this node correspondingly is revised as 0x34F.
In the step 304 of said method, after TPA among the die casting TPA receives the CAN ID of RFU transmission, can judge earlier also whether the CAN ID that RFU sends meets the requirements, if, transmission CAN ID with this node is revised as the CAN ID that RFU sends again, correspondingly revises the reception CANID of this node; Otherwise, abandon this CAN ID.
For example, TPA-A1 receives the CAN ID that RFU-B1 sends, i.e. 0x14F, after, can judge whether this CAN ID is one of 0x10E, 0x14E or 0x18E according to table 1, if then the transmission CAN ID with this node is revised as 0x14E, the reception CAN ID of this node correspondingly is revised as 0x34E; Otherwise, abandon the CAN ID that RFU-B1 sends.TPA-A2 receives the CAN ID that RFU-B2 sends, i.e. 0x14F, after, can judge whether this CAN ID is one of 0x10F, 0x14F or 0x18F according to table 1, if, then the transmission CAN ID with this node is revised as 0x14F, and the reception CAN ID of this node correspondingly is revised as 0x34F; Otherwise, abandon the CAN ID that RFU-B2 sends.
If in transmission course, take place to cause unusually CAN ID to produce error code, will cause TPA-A1 that the transmission CAN ID of this node is revised as wrong CAN ID.By adding such deterministic process, can solve the wrong CAN ID problem that error code causes at TPA.
As can be seen, when die casting TAP is not installed in correct sector,, can make each TPA among this die casting TPA adjust the CAN ID of this node by method of the present invention, thereby make this die casting TPA still can with system's proper communication, thereby make the die casting TPA of different sectors can exchange installation.
For realizing said method, as long as the configurator among TPA and the RFU is carried out small change.By change to the program that disposes among the TPA, make TPA after powering on, the CAN ID of this node be sent to RFU in this sector, and after receiving the CAN ID that RFU sends, the transmission CAN ID of this node is revised as the CAN ID that RFU sends, correspondingly revise the reception CAN ID of this node.By change to the program that disposes among the RFU, make RFU after receiving the CAN ID Req message that TPA sends, the transmission CAN ID of the TPA of this RFU correspondence is sent to TPA in this sector.Because the method that configurator is revised has a lot, just do not introduced one by one here.
Adopt 3 toggle switchs can represent 8 values, and only adopted 0～5 couple of TPA to distinguish at present.In the actual conditions, toggle switch value that also can TPA is set to 6 and 7, is 6 TPA for the toggle switch value, should be identical with the configuration of other toggle switch values TPA (the toggle switch value is 0,2 or 4 TPA) that is even number to the configuration of this TPA; For the toggle switch value is 7 TPA, should be identical with the configuration of other toggle switch values TPA (the toggle switch value is 1,3 or 5 TPA) that is odd number to the configuration of this TPA.
By method provided by the invention, only need one type die casting TPA just can satisfy the needs of base station.One type die casting TPA can be installed in all sectors, after powering on, by the adjustment of each TPA among the die casting TPA to the CAN ID of this node, make die casting TPA in any one sector can with system's proper communication, system is normally moved.
