Embodiment
When base station distribution is very extensive, if do not need the place, place of NODEB/BTS, just can carry out Operation and Maintenance to NODEB/BTS at the central machine room at far-end such as RNC/BSC place, then can make things convenient for the attended operation of base station system to a great extent, thereby can effectively improve the maintainability of base station system, the maintenance cost of reduction base station system.
Therefore, operation and maintenance method to base station system provided by the invention is: intercept by the HDLC time slot between base station maintenance end and the base station system and carry out HDLC time slot coupling, to set up the HDLC link between base station maintenance end and the base station system easily and efficiently automatically, like this, just can set up Operation and maintenance link fast and automatically between base station maintenance end and the base station system based on this HDLC link; Thereby the base station maintenance end can transfer to base station system with the base station system maintenance information by this Operation and maintenance link easily, has realized the remote maintenance of base station system.
Base station maintenance end of the present invention can be realized the automatic remote of the NODEB/BTS in the base station system is safeguarded, also can realize the automatic remote of the RNC/BSC in the base station system is safeguarded.
Because the position of RNC/BSC generally is positioned at central machine room, therefore, base station maintenance end of the present invention can be arranged in the central machine room of RNC/BSC, as is arranged among the RNC/BSC.Certainly, base station maintenance end of the present invention also can be arranged at the position away from RNC/BSC.When the base station maintenance end is arranged at the central machine room place of RNC/BSC, because the distance factor of base station maintenance end and RNC/BSC, so base station maintenance end of the present invention can only be realized the remote maintenance to the NODEB/BTS in the base station system.
Set the base station maintenance end and be arranged among the RNC/BSC,, describe below in conjunction with 2 pairs of technical schemes of the present invention of accompanying drawing in order to realize the remote maintenance of base station maintenance end to NODEB/BTS.
Among Fig. 2, in step 200, the method that the present invention at first need intercept by the HDLC time slot between RNC/BSC and NODEB/BTS is set up the HDLC link automatically.
Then, to step 210, on the basis of the HDLC link that above-mentioned success is set up, set up the ppp link between RNC/BSC and the NODEB/BTS.
Because Operation and maintenance link generally adopts reliable transmission mechanism, so Operation and maintenance link is usually selected ICP/IP protocol for use, like this, to step 220, the present invention is at the Operation and maintenance link of setting up the ICP/IP protocol between RNC/BSC and the NODEB/BTS on the basis of ppp link.
Behind the Operation and maintenance link of having set up automatically by said process between RNC/BSC and the NODEB/BTS, to step 230, the base station maintenance end can be by being sent to NODEB/BTS based on the Operation and maintenance link of HDLC/PPP with the Operation and Maintenance information of base station.Wherein, the ppp link of the implication of HDLC/PPP on the HDLC link, setting up.
To step 240, NODEB/BTS is according to its Operation and Maintenance information and executing relevant maintaining operation that receives, thereby realized the remote maintenance of NODEB/BTS.
Certainly, base station system also can be come some information in base station maintenance end transmission attended operation process by the Operation and maintenance link of above-mentioned automatic foundation, as sending response message etc. to the base station maintenance end.
The present invention is in the Operation and maintenance link process of setting up between RNC/BSC and the NODEB/BTS, and it focuses on: the process of setting up automatically of HDLC link.Below the process of setting up the HDLC link between base station maintenance end and the NODEB/BTS is automatically described.
On the HDLC link, when transmitting terminal sends the fixed format information frame of HDLC with certain several time slot, if the time slot that receiving terminal uses is different with the time slot that transmitting terminal uses, the full message frame that obtains the transmitting terminal transmission that then receiving terminal can not be correct.According to above-mentioned principle, can carry out the time slot coupling of HDLC both link ends between base station maintenance end and the base station system by the method that the HDLC time slot is monitored, when the time slot between base station maintenance end and the base station system mated, the HDLC link was successfully set up.
The present invention can adopt NODEB/BTS to intercept the automatic foundation that the HDLC time slot method realizes the HDLC link between RNC/BSC and the NODEB/BTS, that is to say, in HDLC time slot snoop procedure, RNC/BSC sends the fixed format information frame based on HDLC, NODEB/BTS monitors the HDLC time slot, and whether the message frame of determining its reception is complete message frame, when NODEB/BTS determines that the message frame of its reception is complete message frame, the HDLC time slot coupling of HDLC both link ends, the HDLC link between RNC/BSC and the NODEB/BTS is successfully set up.
Certainly, the present invention also can adopt RNC/BSC to intercept the automatic foundation that the HDLC time slot method realizes the HDLC link between RNC/BSC and the NODEB/BTS.It is basic identical that its implementation procedure and above-mentioned NODEB/BTS intercept the HDLC time slot method, is not described in detail at this.
Below NODEB/BTS being intercepted the HDLC time slot method is described in detail.
When the base station maintenance end was arranged among the RNC/BSC, the present invention at first need dispose the fixed format information frame, reach the HDLC time slot that sends this message frame in RNC/BSC, and the message frame here is also referred to as intercepts bag, intercepts and carries verification and information etc. in the bag.
After having carried out above-mentioned configuration, RNC/BSC begins the HDLC time slot active according to configuration, the fixed format information frame that periodically is used to shake hands to the NODEB/BTS transmission.
NODEB/BTS adopts the HDLC time slot to intercept the HDLC time slot that mode determines that the HDLC both link ends mates, its detailed process can for:
NODEB/BTS disposes this HDLC time slot of intercepting, and the interior at interval at the fixed time fixed format information frame of waiting for the RNC/BSC transmission, if NODEB/BTS receives the fixed format information frame that RNC/BSC sends in this predetermined time interval, then NODEB/BTS resolves this message frame, if in this predetermined time interval, NODEB/BTS parses complete message frame, the HDLC time slot of then representing this setting of NODEB/BTS is identical with the HDLC time slot that RNC/BSC uses, and can adopt this HDLC time slot to set up the HDLC link between NODEB/BTS and the RNC/BSC.
At this moment, the message transmission that NODEB/BTS should mate the HDLC time slot is to the RNC/BSC place, and the match is successful to make RNC/BSC learn the HDLC time slot.In the response process of above-mentioned HDLC time slot match information, NODEB/BTS can respond repeatedly the information of HDLC time slot coupling continuously to RNC/BSC, continuously to the information of 3 HDLC time slot couplings of RNC/BSC response, the match is successful to guarantee can to know the HDLC time slot by RNC/BSC as NODEB/BTS.
RNC/BSC stops to send the fixed format information frame that is used to shake hands to NODEB/BTS after knowing the HDLC time slot the match is successful.
If in this predetermined time interval, NODEB/BTS does not receive the message frame that RNC/BSC sends, and then NODEB/BTS continues to wait for the message frame that RNC/BSC sends in next predetermined time interval.
If in this predetermined time interval, NODEB/BTS does not parse complete message frame, represent that then the HDLC time slot of this setting of NODEB/BTS and the HDLC time slot that RNC/BSC uses are inequality, can not adopt this HDLC time slot to set up the HDLC link between NODEB/BTS and the RNC/BSC.Like this, NODEB/BTS can reconfigure the HDLC time slot of next time intercepting, and continue to wait for the fixed format information frame that RNC/BSC sends in the interval at the fixed time, repeat the process that above-mentioned message frame is resolved, intercept out identical with the HDLC time slot of RNC/BSC use up to NODEB/BTS.
Because NODEB/BTS determines the coupling time slot of HDLC link automatically by intercepting mode, like this, for the time of intercept that reduces NODEB/BTS, improve that the HDLC time slot is intercepted success rate and the HDLC time slot is intercepted efficient, the present invention can carry out can only disposing on the E1 of following restriction: NODEB/BTS a PPP group to the time slot configuration among NODEB/BTS and the RNC/BSC, and the time slot that disposes among NODEB/BTS and the RNC/BSC is continuous.
Intercept after process finishes at the HDLC time slot, RNC/BSC starts the ppp protocol negotiations process, to realize the negotiation of PPP/MLPPP (Mutli-Link PPP, Multi-link Point to Point Protocol).That is to say, after having set up the HDLC link automatically between RNC/BSC and the NODEB/BTS, need set up ppp link on the basis of HDLC link, promptly carry out the ppp link detection-phase, its detailed process is:
If the HDLC time slot is intercepted the stage success, then the HDLC link sends UP message to ppp link, base station system enters ppp link and detects and configuration phase, and the automatic acquisition process of IP to MLPPP link detecting stage in ppp link detection and the configuration phase and PPP/MLPPP link group carries out the emphasis description below.
The MLPPP link detecting stage: after the ppp link group of a link starts successfully, need whether to adopt the MLPPP link between further base stations detected and the base station controller, therefore, this stage through consultation process realize that promptly the process of intercepting automatically by MLPPP realizes.
NODEB/BTS initiates to consult on ppp link, send the message of carrying the MRRU value to RNC/BSC, support the ML ppp protocol to show oneself, RNC/BSC according to the MRRU value of carrying in the message, judges NODEB/BTS and supports the ML ppp protocol after receiving this message, then respond NODEB/BTS, promptly Endpoint Discriminator is transferred to NODEB/BTS, thereby, make NODEB/BTS can distinguish which ppp link and belong to a ML PPP.
After the MLPPP link detecting stage finishes, enter NCP (network configuration stage) stage, at this moment, RNC/BSC and NODEB/BTS all use IPCP (IP address configuration agreement).
The IP address information of PPP/MLPPP link group is obtained the stage automatically: NODEB/BTS is at ipcp phase, send IP address configuration request message to RNC/BSC, the IP address field of NODEB/BTS in IP address configuration request message, the IP address of oneself is extended this as 0, need the address information of RNC/BSC configuration NODEB/BTS with expression.RNC/BSC sends NAK message to NODEB/BTS after receiving this IP address configuration request, its IP address that disposes for NODEB/BTS is filled in in the NAK message, thereby the IP address of having realized NODEB/BTS disposes automatically.
After the automatic configuration in the IP address of NODEB/BTS was finished, the IP transmission between NODEB/BTS and the RNC/BSC just can normally move.From foregoing description as can be seen, the present invention has adopted in HDLC link establishment process, in the HDLC/PPP link establishment process and intercepted implementation method automatically from the bottom to the high level, has guaranteed the normal operation of IP transmission fast and effectively.Certainly, the IP address that can also adopt additive method to dispose NODEB/BTS transfers to NODEB/BTS etc. as utilizing the HDLC link set up with the IP address information of NODEB/BTS.The present invention after adopting the method intercept automatically to set up the HDLC link, the method for the IP address of limitation arrangement NODEB/BTS not.
On the basis of above-mentioned HDLC/PPP link, the IP address that the present invention can obtain the Operation and maintenance link of NODEB/BTS by BOOTP (BOOT strapping Protocol) process.Concrete BOOTP process as shown in Figure 3.
Among Fig. 3, send BOOTP request command, i.e. BTS/NODEB OML Bootp Request to RNC/BSC at step 3-1, BTS/NODEB.
To step 3-2, BSC/RNC after receiving the BOOTP request command, according to this BOOTP request command from link number and the configuration data, obtain the IP address of the OML of this NODEB/BTS, and the IP address information of the OML of NODEB/BTS returned to BTS/NODEB by the BOOTP response message, promptly return BSC/RNC Bootp Response to BTS/NODEB.
Certainly, the present invention also can dispose the IP address of the OML of NODEB/BTS by additive method, at present, the method of the IP address of the OML by HDLC/PPP link configuration NODEB/BTS is a lot, as utilizing the HDLC link set up that the IP address information of the OML of NODEB/BTS is directly transferred to NODEB/BTS etc., the present invention after adopting the method intercept automatically to set up the HDLC link, the method for the IP address of the OML of limitation arrangement NODEB/BTS not.
Because Operation and maintenance link generally adopts reliable transmission mechanism, therefore, Operation and maintenance link is usually selected ICP/IP protocol for use, like this, behind the OML link of successfully having set up between NODEB/BTS and the RNC/BSC, because this moment, the server side of Operation and maintenance link was that the IP address of RNC/BSC side and IP address that client-side is the NODEB/BTS side are all clear and definite, and the tcp port number of server is a well-known port number, therefore, with NODEB/BTS is client-side, with RNC/BSC is server side, sets up the TCP connection and get final product between NODEB/BTS and RNC/BSC, to finish the foundation of OML link.The process of setting up of concrete OML link as shown in Figure 4.
Among Fig. 4, send a BTS/NODEB OMLConnect Request (OML connection request) at step 4-1, BTS/NODEB to RNC/B SC, with the port numbers that the OML that indicates BTS/NODEB plans connection, this port numbers is determined for the OML link.
After receiving BTS/NODEB OML Connect Request, send a response message to NODEB/BTS to step 4-2, RNC/BSC, i.e. BSC/RNC OML Connect Ack is to carry out the affirmation of above-mentioned port numbers.
To step 4-3, NODEB/BTS after receiving BSC/RNC OML Connect Ack, send a confirmation message to RNC/B SC, be BTS/NODEB OML Connect Confirm, to finish the OML link establishment process between NODEB/BTS and the RNC/BSC.
Certainly, the present invention also can set up OML link between NODEB/BTS and the RNC/BSC by additive method, and the present invention does not limit the method for setting up the OML link after adopting the method for intercepting automatically to set up the HDLC link.
Behind the OML link of having finished between NODEB/BTS and the RNC/BSC, just can download and data, to realize remote operation maintaining to NODEB/BTS by the OML link.The present invention has realized NODEB/BTS is carried out the automatic foundation of the Operation and maintenance link of remote operation maintaining fully, the process of having avoided the attendant to carry out the configuration of HDLC chain time gap to widely distributed base station side has realized long-range, high efficiency NODEB/BTS remote base stations maintenance.
