Embodiment
The present invention makes the base station have the function of base station controller by additional corresponding radio resource management function in the base station.See also Fig. 2, this method may further comprise the steps:
1, configurating base station static parameter, and support is to the modification of parameter
The base station static parameter comprises parameters such as cell configuration, veneer configuration, base station property, carrier frequency attribute, channel attribute.
In the opening base station process, need the parameter revised for part,, support modification it as cell configuration, veneer configuration, clock module, rate of static power etc.
2, initialization base station guarantees that the base station goes into operation
The base station initialization comprises website initialization and cell initialization.
Wherein, the website initialization comprises that the network of object logic, the configurating base station hardware device of configurating base station, the attribute that website is set, configuration site connects.
Cell initialization comprises to be set up terminal node indication, sets up signaling and connect, set up and professionally connect, cell attribute is set, the carrier frequency attribute is set, channel attribute is set, alarming threshold is set, the enable logic object, change the controlled state of object logic.
3, transmitting system message is to realize the access of travelling carriage
The transmission of system message realizes the control to the travelling carriage access, is the foundation that travelling carriage inserts.System message is broadcasted on broadcast channel and channel associated signalling channel, and content comprises characteristics such as the wireless channel frequency, power of Serving cell and adjacent cell characteristic etc.
Wherein the system message of broadcasting on the broadcast channel travelling carriage that is used for Idle state obtains mobile network information and access network; The system message of broadcasting on the channel associated signalling channel is used for the foundation and the release of the travelling carriage communication process signaling of conversation state.
4, foundation and release voice channel, Analog Voice Channel is set up process
Set up process (comprising the foundation and the release of voice channel) by Analog Voice Channel, the working condition of base station is verified.Simulation process is by finishing to base station transmitting channel activation command, and the parameter of order comprises link No., carrier frequency number, timeslot number, channel type of base station controller and inter-base station interface etc.
See also Fig. 3; when above-mentioned mobile communcations system is Golbal System for Mobile Communic-ations; by additional radio resource management function in base transceiver station through optimizing; comprise static parameter broadcast channel BCCH to the base station; rapid data channel SDCCH and voice channel TCH adopt the mode of fixed allocation to simplify setting; be optimized for the affirmation message in the base transceiver station initialization procedure; in voice channel activation, only activate a channel at every turn; thereby make base transceiver station have the simplest function of anolog base station controller, to guarantee going into operation and the foundation of control channel and voice channel of base transceiver station.
1, the simplification of disposing for the base station static parameter
In the actual use of base transceiver station, has certain flexibility: promptly generally determine configuration 1 or a plurality of broadcast channel BCCH according to the carrier frequency quantity of sub-district for the configuration of sub-district in the base transceiver station static parameter; According to the demand of sub-district, can dispose 1 or a plurality ofly also can dispose SDCCH for rapid data channel SDCCH.
For the simplified system design, do not need flexible configuration when considering the base transceiver station commissioning simultaneously to channel yet, in the base transceiver station of anolog base station controller function: for the mode of broadcast channel BCCH, rapid data channel SDCCH and voice channel TCH employing fixed allocation, be about to 0 time slot of BCCH fixed configurations at first carrier frequency of each sub-district, SDCCH is configured in 1 time slot of first carrier frequency, and remaining all time slot all is configured to the TCH channel.
2, for the simplification of base transceiver station initialization procedure
Regular flow process is to await a response after sending a piece of news, sends a piece of news down again after receiving acknowledge message.Because there is certain randomness in the message of base transceiver station uploaded state change report, when sending the website starting command, the transmit status change report before the response that sends starting command often of actual base transceiver station reporting message.
For the simplified system design, consider above-mentioned factor simultaneously, in the base transceiver station initialization procedure of anolog base station controller function, deleted the process of waiting for the starting command response.
3, for the simplification of voice channel activation:
In the actual use of base transceiver station, finish activation and releasing operation to corresponding voice channel according to the call request situation.Promptly,, just distributed as long as there is idle voice channel when the bid request.
For the simplified system design, the voice channel foundation of considering anolog base station controller function base transceiver station simultaneously is the processing procedure of simulation with dispose procedure, only activates a channel in the voice channel activation of anolog base station controller function base transceiver station at every turn.
See also Fig. 4; when above-mentioned mobile communcations system is broadband CDMA system; by additional radio resource management function in the base station, make the base station have the simplest function of analog wireless networks controller, to guarantee going into operation and the foundation of control channel and voice channel of base station through optimizing.The simplest function comprises that initialization, the system message of website initialization, sub-district send and the foundation of voice channel.
