Description
Technical field
The present invention relates to the maintenance of wireless network, relate in particular to a kind of method of remote maintenance NodeB.
Background technology
Along with development of wireless communication devices, communication network becomes increasingly complex and is huge, and the maintainability of network is had higher requirement.3G (3rd Generation Mobile Communication, 3G (Third Generation) Moblie) network is at WCDMA (Wide-band Code Division Multiple Access, WCDMA access system), CDMA2000 (Code Division Multiple Access2000, CDMA 2000), TD-SCDMA (Time Division Synchronization Code Division Multiple Access, the time division multiplexing S-CDMA) maintenance channel between regulation base station controller of the agreement in the communication system and the base station adopts IPOA (IP over ATM, IP on the ATM) form, but and the mode of setting up of the maintenance channel between undefined base station controller and the base station.
Figure 1 shows that the protocol architecture schematic diagram when NodeB is set up the IPOA maintenance channel, the prerequisite of IPOA maintenance channel operate as normal is all correctly configuration of each layer among the figure, the configuration that is to say base station side will be mated fully with the configuration of side of base station controller, and this data configuration by the attendant is difficult to guarantee, particularly when building a station, can not guarantee that the initial configuration and the side of base station controller of base station side are in full accord.
For addressing the above problem, application number is 01136795.4, and name is called in the Chinese invention patent prospectus of " a kind of method for building up of the default maintenance channel based on the IPOA passage " discloses a kind of method of setting up automatically based on the maintenance channel of IPOA between base station and base station controller.This method does not need to carry out in advance any data configuration in base station side, but disposes by the default IPOA that obtains self to side of base station controller, thereby sets up a default IPOA maintenance channel.This method needs based on following prerequisite: the one, transmit based on ATM (Asynchronous Transfer Mode, asynchronous transfer mode) between base station and the base station controller; The 2nd, set up physical connection between base station and the base station controller.
In the method, the physical link testing mechanism and the Bootstrap Protocol (BOOTP) of bottom adopted in the base station when not detecting available IPOA passage, sets up the default maintenance channel based on IPOA automatically.Because having set up physical layer between base station and the base station controller is connected, this physical layer connects can be based on UNI (User Network Interface, User Network Interface) mode or based on IMA (InverseMultiplexing on ATM, Inverse Multiplexing over ATM) mode.Which kind of mode the base station can be by what intercept that cell on the link judges employing, thereby obtain the physical link data of base station controller configuration, so just can set up default permanent virtual and connect (PVC), agreement Virtual Channel Identifier (VPI)=1/ virtual channel identifier (VCI)=33.At this above default PVC, the BOOTP request is initiated with broadcast mode in the base station, by base station controller system's centralized operation maintenance console is delivered in this request, the centralized operation maintenance console is given base station assigns IP address, insert in the BOOTP respond packet, by base station controller the base station is delivered in this BOOTP response, last base station gets access to the IP address of distributing to it, create the IPOA passage according to this IP address and default PVC, thus the foundation of complete operation maintenance channel.
After NodeB adopts said method to set up the IPOA maintenance channel, the protocol hierarchy complexity when using the IPOA maintenance channel, any one deck is because configuration or other reason occur unusually all can causing the IPOA maintenance channel to lose efficacy.The BOOTP agreement has following limitation on using in addition:
1, when the physical layer connection is based on UNI/IMA, the UNI/IMA configuration of opposite end can be intercepted out in the base station, when the physical layer connection is based on Fractional ATM (burst ATM), Fractional ATM (burst ATM) configuration of opposite end can't be intercepted out in the base station, therefore when the IUB mouth adopted Fractional ATM configuration, the BOOTP agreement was limited on using.
2, the BOOTP agreement arrange default IPOA maintenance channel must be configured in it seems the link of E1/T1 minimum from the base station end on, this has brought very big inconvenience for IUB mouth data configuration.
3, in the BOOTP flow process, it is that icp cell by detecting in FIFO (First In First Out, the first in first out) buffer is realized that the base station carries out that IMA intercepts.Under the existing IMA configuring condition of this link, its FIFO will in time be read and be emptied, and therefore carry out occurring possibly when IMA intercepts FIFO and will detect less than icp cell for empty, and cause IMA to intercept the situation of failing or not listening to smallest link.For the validity that guarantees that intercept cell the base station in the BOOTP flow process, just can not remove to read FIFO, service disconnection is unavoidable like this.
4, whether needing to start the BOOTP flow process can not be by the remote subscriber control of side of base station controller, can only be by base station side according to its state independent judgment, its judged result wish frequent and user is opposing, often started the BOOTP flow process when the user is undesirable, the BOOTP flow process perhaps delays to start when the user wishes.
