Abstract
The method comprises: a) base station uses a configuration of time slot to establish FRAAT link; b) the base station decides if an asynchronous transmission mode (ATM) between radio network controller (RNC) or base station controller and itself can be established on said FRAATM; if yes, then entering into step c; otherwise, returning to step a; c) base station gets its own IP address allocated by RNC or BSC, and according to the IP address, establishes the IPOA channel for use in maintenance between RNC or BSC and itself.
Description
Technical field
The present invention relates to 3G mobile communication system Operation and Maintenance technology, relate in particular to the method for between base station (NodeB or BTS) and radio network controller (RNC) or base station controller (BSC), setting up OM channel in the 3G mobile communication system.
Background technology
Regulation according to 3G mobile communication system agreement, in communication systems such as WCDMA, CDMA2000 and TD-SCDMA, should set up the IP (IPOA on the ATM(Asynchronous Transfer Mode) that is used for Operation and Maintenance between base station and RNC or the BSC, IP over ATM) passage is so that RNC or BSC utilize this passage the base station is conducted interviews and to safeguard from far-end.Because it is identical to set up the method for OM channel between the method for setting up OM channel between base station and the BSC and base station and the RNC, for narrating for purpose of brevity, is example with the method for setting up OM channel between base station and the RNC only hereinafter.
Current, the method for setting up the IPOA passage between base station and RNC mainly comprises following two kinds.
1) by the attendant in advance in the relevant IPOA data of base station side and RNC side configuration, if data configuration is correct, RNC can conduct interviews to the base station and safeguards from far-end.But this maintenance mode is very inconvenient and make mistakes easily, in case data configuration is incorrect, RNC just can't conduct interviews and safeguards the base station.
2) set up the method for IPOA passage automatically by BOOT strapping Protocol (BOOTP), this method is applicable to mainly that current physical connection between base station and the RNC adopts the occasion of Inverse Multiplexing over ATM (IMA) mode or User Network Interface (UNI) mode.
Fig. 1 is a flow chart of setting up the method for IPOA passage in the prior art by BOOTP, and in Fig. 1, physical connection between base station and the RNC adopts IMA mode or UNI mode, and the method for setting up the IPOA passage by BOOTP in the prior art comprises:
Step 101～104:: RNC sidelinks situation is known by intercepting in the base station, confirms that promptly RNC has adopted the IMA mode still to adopt UNI mode; Corresponding IMA link or UNI link are set up in the base station, and send the BOOTP request package to RNC on IMA link of being set up or UNI link; RNC returns the BOOTP respond packet of carrying the IP address of distributing to the base station and gives the base station on IMA link of being set up or UNI link; The base station is according to the IP address that obtains from the BOOTP respond packet, creates the IPOA passage between self and the RNC, process ends.
Wherein, because IMA mode and UNI mode have utilized whole 32 time slots of E1 or T1 to transmit ATM cell, so RNC sidelinks situation can be known by monitoring in the base station, confirm that just RNC has adopted the IMA mode still to adopt UNI mode, thereby set up corresponding IMA link or UNI link bearer channel as IPOA.
But, in actual applications, physical connection between base station and the RNC is except may adopting IMA mode or UNI mode, also may adopt the FRAATM mode, the FRAATM mode is meant that the some time slots in whole 32 time slots that only utilize E1 or T1 transmit ATM cell, it is mutual that this just requires base station and RNC must adopt identical time slot configuration just can carry out ATM cell, for instance, if the base station configuration as transmitting terminal is to utilize 30 time slots of E1 to send ATM cell, the RNC as receiving terminal must be configured to utilize 30 time slots of E1 to receive ATM cell equally so.
Therefore, when the physical connection between base station and the RNC adopts the FRAATM mode, identical time slot configuration must be adopted with RNC in the base station, but, regulation according to the FRAATM related protocol, base station and RNC must carry out time slot configuration independently of each other, and this just causes the base station can't know the time slot configuration that RNC adopts, and also just can't set up the bearer channel of corresponding FRAATM link as IPOA.
As seen, when the physical connection between base station and the RNC adopts the FRAATM mode, can't between base station and RNC, set up the IPOA passage that is used for Operation and Maintenance by BOOTP in the prior art.Same, when the physical connection between base station and the BSC adopts the FRAATM mode, also can't between base station and BSC, set up the IPOA passage that is used for Operation and Maintenance in the prior art by BOOTP.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method of setting up OM channel, make when the physical connection between base station and RNC or the BSC adopts the FRAATM mode, also can between base station and RNC or BSC, set up the IPOA passage that is used for Operation and Maintenance by BOOTP.
