Abstract
The invention discloses a method of processing the system information during the course of baseband distribution. A baseband unit receiving base station controller sends the system information and caches the information. When the baseband resources allocation is carried out for the carrier frequency, the baseband unit transmits the cached system information to the baseband resources for the carrier frequency allocation. Meanwhile, the invention also discloses a system to process the system information during the course of the baseband distribution. The system comprises the baseband unit and a remote radio frequency unit. The baseband unit comprises a baseband processing unit, while the baseband processing unit comprises a system information control module consisting of a system information operation sub-module and a system information caching sub-module. The invention realizes that when the virtual carrier frequency moving happens, the corresponding system information is transmitted to the new baseband resources for the carrier frequency re-allocation, so the working stability and the reliability of the base station are improved greatly.
Description
Technical field
The present invention relates generally to moving communicating field, relates in particular to method, system and the Base Band Unit of treatment system message in a kind of base-band resource distribution.
Background technology
Generally, global system for mobile communications (GSM, Global System for MobileCommunication) the network service area territory is divided into a plurality of sub-districts, and be each cell configuration relevant base station transceiver station (BTS, Base Transceiver Station), in order to provide wireless network to cover.In gsm system, (TRX Transceiver) constitutes the base station transceiver communication system, and every radio receiving-transmitting unit is used for eight Signal Processing, wireless receiving and wireless transmission on the physical slot by time by one or more radio receiving-transmitting unit.According to the operation principle of radio receiving-transmitting unit, radio receiving-transmitting unit can be divided into RF processing unit and Base Band Unit, Base Band Unit adopts data signal processor (DSP, Digital SignalProcessor) to realize usually.For each sub-district, the network maintenance staff can be the one or more radio receiving-transmitting units of this cell allocation according to the estimation to traffic carrying capacity in this sub-district, handles the conversation and the data transmission service that are positioned at this sub-district user.
In the real network environment, the distribution of the traffic carrying capacity in the sub-district on different time is very uneven.For example, the traffic peak of a sub-district is likely the several times of its average traffic, if according to traffic peak is the fixing baseband equipment of cell configuration, then can cause the baseband equipment that is disposed not used fully in the most of the time, caused the waste of base-band resource.Because the base-band resource between a plurality of sub-districts can be realized sharing, therefore, if in a certain moment, the traffic carrying capacity of a sub-district is very little, and the traffic carrying capacity of another sub-district is when very big, then the base-band resource of sub-district that can traffic carrying capacity is little offers the big sub-district use of traffic carrying capacity, thereby makes the base-band resource of a plurality of sub-districts form complementation.For example, for adjacent each other industrial area and residential area, a traffic carrying capacity is big often in the most of the time for the cell business volume of the two, and a traffic carrying capacity is less relatively, thereby can satisfy the situation of base-band resource complementation.Therefore, if just can realize maximum using the base-band resource flexible allocation of two sub-districts can for the sub-district that needs, thereby save equipment cost greatly to the base-band resource in an area.But the base-band resource in the existing gsm system be distributed in the subzone network initial plan time just determine, and base-band resource and radio frequency resource often one by one correspondence can not separate.
In order to address the above problem, introduce the radio frequency stretch system framework.The main thought of radio frequency stretch system is that base transceiver station is split, the base-band resource of base transceiver station is separated with radio frequency resource, form two independent parts, Base Band Unit (BBU, Baseband Unit) and radio frequency far put unit (RRU, Remote Radio Unit).Wherein, Base Band Unit concentrates in together a plurality of base-band resources, forms a base band resource pool, and far putting the unit for a plurality of radio frequencies provides base-band resource to share; Radio frequency is far put the unit and is used for signal is carried out radio frequency processing; Base Band Unit is far put the unit with radio frequency and is adopted optical fiber to be connected.Each base-band resource is for handling the base-band resource of all wireless channels on the carrier frequency.Just because of this framework has been realized separating of base-band resource in the base transceiver station and radio frequency resource, thereby make the dynamic assignment of base-band resource become possibility.
But there is a difficult point in prior art on the dynamic assignment of base-band resource, exactly when the sub-district in the broadcasting of carrying out system message with when upgrading, should how to solve the dynamic assignment of base-band resource.Because for base station controller (BSC, Base Station Controller), after base transceiver station powers on, system message just is sent in each carrier frequency of base transceiver station, when the generation virtual carrier frequency is moved (VCS, Virtual Carrier Shifting), the pairing system message of each carrier frequency also should be moved in the new base-band resource in principle, but system message generally is kept in the baseband processing unit, can't directly move.It is to cause owing to the base-band resource of distributing to carrier frequency or radio frequency resource change that described virtual carrier frequency is moved, for example, certain carrier frequency has been assigned with first base-band resource, this first base-band resource is related with first radio frequency resource, this first radio frequency resource is in A ground, because the variation of cell telephone traffic amount, for first base-band resource of this carrier frequency distribution is retracted, again be assigned with second base-band resource, this second base-band resource is related with second radio frequency resource, this second radio frequency resource is in B ground, therefore for carrier frequency, has realized moving to the virtual of B ground from A ground.
Prior art often adopts the method for asking base station controller sending system message again, and this method not only response speed is slow, and has increased the live load of base station controller.
