Description
Technical field
The present invention relates to the processing method of maintenance channel, refer to a kind of method for building up of remote maintenance channel especially.
Background technology
Along with development of wireless communication devices and the people expansion day by day to communication requirement, communication network is more and more huger and complicated, requires also more and more higher to the maintainability of network.But, the default maintenance channel of undefined base station in the related protocol of 3-G (Generation Three mobile communication system), make the base station when initially setting up, can't not set up maintenance channel owing to set up the required configuration data of maintenance channel, or base station controller (RNC) occurs and can't the far-end operation base station etc. can't rebulid maintenance channel during communication failure, the problems referred to above bring very big inconvenience for the maintenance work of base station.
At present, initially set up or communication failure occurs for the base station and cause the situation that RNC can't the far-end operation base station, the main employing manually safeguarded to the method for near-end intervention, divide by the attendant and to be clipped to base station side and the maintenance channel desired data is set up in the configuration of RNC side, to set up the maintenance channel between base station and the RNC, thereby solve the problem that the base station normally goes into operation and moves, realize the far-end operation of RNC the base station.But the base station usually is positioned at remote bleak and desolate place in the practical application, realize the human configuration of base station very difficult; And, if it is very far away to be separated by between base station and the RNC, adopt human configuration to occur the nonsynchronous phenomenon of configuration between base station and the RNC easily.So, thisly manually not only can bring a large amount of maintenance costs to the method for near-end intervention, also can bring big inconvenience to troubleshooting.
Defective at said method, prior art proposes a kind of automatic method for building up of remote maintenance channel, utilize default PVC to connect, base station and RNC set up the special maintenance passage, download the data configuration file of this base station from the RNC side, utilize institute's data downloaded configuration file to set up remote maintenance channel between base station and the RNC then, finally realize the far-end operation of RNC this base station.Described remote maintenance channel is meant the communication port that is used for the transmission maintenance data between base station and RNC, this remote maintenance channel can be used for the base station from RNC side download-maintenance software, perhaps alarm data is uploaded to the RNC side in the base station, and perhaps the RNC side sends debug command and arrives base station etc.Among the application RNC and centralized operation maintenance console are referred to as the RNC side, wherein the centralized operation maintenance console is a control unit, is responsible for control command and configuring base station data are sent in the base station; RNC is responsible for communicating with the base station, and the control command of centralized operation maintenance console need just can send to the base station through RNC.The described required data configuration file of remote maintenance channel of setting up is provided with by the centralized operation maintenance console, and is stored in the centralized operation maintenance console.When described base station needed the data download configuration file, the centralized operation maintenance console sent to RNC with the data configuration file of self storage, by the maintenance channel between RNC and the described base station data configuration file is sent to described base station.The content of data configuration file comprises: receive path delay compensation, receiving antenna mode, reception GBUS mode of operation, sendaisle delay compensation, RRU connection mode, base station edition number, veneer configuration data, User Network Interface (UNI) or asynchronous transfer mode inverse multiplexing (IMA) data, Access Link Control Application Protocol (ALCAP) data, base stations control port (NCP) or communication context port (CCP) data, IPOA channel arrangement data, clock data, sector data, and the home cell data etc.Wherein, IPOA channel arrangement data comprise IP address and PVC attribute.Wherein, setting up the required IP address of IPOA passage comprises: the IP address of IP address, base station and RNC.
The automatic method for building up of described remote maintenance channel is based on following prerequisite: set up physical connection between described base station and the RNC, and based on the ATM mode transfer.In case this base station and RNC set up physical connection, the centralized operation maintenance console just is provided with data configuration file for this base station.Wherein, the centralized operation maintenance console is as follows to being provided with of the IPOA channel arrangement data in the data configuration file: the centralized operation maintenance console carries out unified planning to all IP addresses, base station in advance.Herein, the centralized operation maintenance console can distribute according to the area of base station and plan IP address, base station.According to program results, the centralized operation maintenance console is that described base station is provided with an IP address, guarantees that IP address, this base station does not produce with the IP address of other base station conflict, and permanent virtual connection (PVC) attribute of this base station is set.In the following description, the Operation and Maintenance platform is A with described base station IP address setting in the hypothesis set.
As shown in Figure 1, the automatic method for building up of this remote maintenance channel of prior art may further comprise the steps:
Step 101: the base station adopts the default attribute foundation of PVC and the default PVC between the RNC to connect, and connects by default PVC and sends Bootstrap Protocol request (BOOTP request) to the centralized operation maintenance console, application IP address.
Agreement regulation: the base station needs Virtual Path Identifier (VPI) and could set up with the PVC of RNC with the configuration data of Virtual channe identifiers (VCI) and be connected, and sets up PVC and is connected required PVC attribute so among the application VPI and VCI be called.In the practical application, equipment manufacturers set in advance the PVC attribute of base station before dispatching from the factory in the base station, and this PVC attribute adopts the PVC default attribute of agreement regulation, that is: VPI=1, VCI=33.
Step 102: after the centralized operation maintenance console is received BOOTP request message, give in the step 101 and send the IP address, base station of a free time of base station assigns of BOOTP request message, and the Bootstrap Protocol response (BOOTP response) that will carry this IP address sends to the base station of sending BOOTPrequest message by RNC.
In this step, after the centralized operation maintenance console is received the BOOTPrequest message of the application IP address of sending the base station, need according to current system IP occupation condition the IP address of this free time of base station assigns, suppose that this IP address is B, the IP address, base station of then carrying in the BOOTP response message is B, the IP address that also can carry RNC in the while BOOTP response message, the IP address of supposing RNC is C.
Step 103: after BOOTP response message is received in the base station of sending BOOTP request message, from this message, obtain the IP address C of base station IP address B and RNC, set up special maintenance passage between self and the RNC automatically according to the IP address that obtains and PVC default attribute.
In this step, the special maintenance passage is that the PVC attribute is VPI=1, VCI=33, and IP address, base station is B, and the IP address of RNC is the IPOA passage of C.The IPOA passage of setting up between base station and the RNC comprises two parts content: at first, the PVC that sets up between base station and the RNC connects; Secondly, the base station is according to the IP address B configuration its own IP address that obtains from BOOTP response message, and RNC also is configured to C with its own IP address.Wherein, if the IP address configuration of RNC is just finished when the RNC initial configuration, herein needn't be again the IP address of RNC be configured.Finish after above-mentioned two steps, the IPOA passage between base station and the RNC is just set up.Suppose to send a packet from the base station to RNC, the source IP address of this packet is B so, and purpose IP address is C, and this packet is based on the ATM transmission, so need pass to the RNC side from the base station by the PVC connection.
From the above, the base station need know and distribute to its own IP address B, the IP address C of RNC and the PVC attribute of IPOA passage could be set up and RNC between the IPOA passage.
Step 104: the special maintenance passage is passed through from RNC side data download configuration file in the base station of sending BOOTP request message.
Wherein, the IPOA channel arrangement data in the data configuration file are that the centralized operation maintenance console is this base station assigns, and IPOA channel arrangement data comprise: IP address and PVC attribute.Wherein, setting up the required IP address of IPOA passage comprises: the IP address of IP address, base station and RNC.
In the practical application, the centralized operation maintenance console is saved in the data configuration file of corresponding base station for each base station is provided with the IP address.In a single day these IP addresses are assigned with, and are not the IP addresses of idle condition just, so the centralized operation maintenance console is that IP address, the base station A that is provided with in the data configuration file of IP address, the base station B of special maintenance channel allocation and this base station is different in the step 102.The centralized operation maintenance console also can be saved in the IP address of RNC in the data configuration file of base station, and the IP address of supposing RNC is C.
The centralized operation maintenance console also can be saved in the data configuration file of corresponding base station for each base station is provided with the PVC attribute, and this PVC attribute is different with the PVC default attribute of agreement regulation.Suppose in the present embodiment that the centralized operation maintenance console is that the PVC attribute that described base station is provided with is VPI=7, VCI=100.
Step 105: after data configuration file was downloaded and finished, base station resets adopted IPOA channel arrangement data and RNC in institute's data downloaded configuration file to set up remote maintenance channel, thereby realized the far-end operation of RNC to the base station.
After reset operation was carried out in the base station, all the elements that comprise according to data configuration file disposed relevant base station data.Such as: the base station adopts IPOA channel arrangement data and the RNC in the data configuration file to set up remote maintenance channel.
By data downloaded configuration file in the step 104 as can be known, the remote maintenance channel of setting up in this step is that the PVC attribute is VPI=7, VCI=100, and IP address, base station is A, and the IP address of RNC is the IPOA passage of C.
From above-mentioned steps 101～105 as can be seen, when RNC can't carry out far-end operation to the base station, the base station obtained the IP address by setting up default PVC connection from RNC, sets up the special maintenance passage.This special maintenance passage is interim foundation of communication failure of setting up or repairing for the base station is initial between RNC and the base station, is used for the base station and obtains data configuration file from the RNC side, so this maintenance channel is called the special maintenance passage.In the practical application, this special maintenance passage is the IPOA passage.The base station will reset to self after obtaining data configuration file from the RNC side, set up remote maintenance channel then.
Prior art adopts to be set up remote maintenance channel automatically and realizes that there is following defective in RNC to the base station far-end method of operating: cause the situation that RNC can't the far-end operation base station for communication failure occurring, though existing IPOA passage as remote maintenance channel can't normally use, the PVC attribute is VPI=7 in the existing remote maintenance channel but RNC is still for this base station keeps, the PVC of VCI=100 connects, this PVC connects still occupied bandwidth resource, the base station utilizes default PVC to connect by the described process of step 101 and sends BOOTP request message simultaneously, and the default PVC that sends BOOTP request message connects also occupied bandwidth resource.In this case, a base station can take two PVC simultaneously and connect, so the waste that this method of prior art can be brought system bandwidth.When the number of base stations of being responsible for safeguarding as RNC reaches thousands of, this bandwidth waste especially severe that becomes, even can cause the Traffic Channel bandwidth occupancy.
If for fear of bandwidth waste, when RNC need be in the base station can't normally use as the IPOA passage of remote maintenance channel, the corresponding PVC of deletion connected.Though such processing method has been avoided bandwidth waste, has increased maintenance workload to RNC, strengthen the maintenance cost of RNC.
From top analysis as can be seen, prior art or bring higher maintenance cost perhaps causes the serious waste of bandwidth, can't avoid above-mentioned two shortcomings simultaneously.
