Embodiment
For making the purpose, technical solutions and advantages of the present invention express clearlyer, the present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In embodiments of the present invention, networking mode is more flexible, increases to hand over the packet header routing iinformation to adapt to the various network construction forms of remote radio base station in grouped data to be exchanged.Owing to do not need database or the swap table information of maintain configuration data channel properties, reduced realization, debugging and the maintenance difficulties of equipment.The configuration of every DBMS passage only needs the routing iinformation of data query get final product, and data abandon used routing iinformation after arriving destination address, and other routing iinformations continue to transmit, and processes simple and reliablely, and it is few to take resource.
Be BBU Base-Band Processing framework referring to accompanying drawing 1, baseband processing unit is processed the data flow of many residential quarters, and by a plurality of smooth port transmission data to the RRU network.The processing of multi-cell multi-antenna data divides in different B BU and different RRUs and realizes, need to dispose according to different network construction forms corresponding data channel like this.
Are method for interchanging data schematic flow sheets in the video remote base station referring to accompanying drawing 2, specifically may further comprise the steps:
Determine grouped data according to power system capacity and specific targets.Grouped data is the least unit of exchanges data in the remote radio base station.Packet Data Unit can be the data among data corresponding to an antenna of a residential quarter in data corresponding to a residential quarter in the radio frames, the subframe or the antenna carrier container A xC.
In the processing at different levels of physical layer, increase the packet header routing iinformation that provides for grouped data.The packet header routing iinformation is along with the data of grouped data are transmitted in radio frequency remote base station jointly.The Baotou Road by information comprise that cell index, light stomochord draw, any one or combination in the radio frequency remote unit RRU in aerial position index, the RRU progression index.
Step 202, physical layer routing link device at different levels are according to the passage of described Baotou Road by the described grouped data of information configuration.
In physical layer routing link devices at different levels, according to the passage of Baotou Road by the information configuration grouped data, add simultaneously the routing iinformation that physical layer at the corresponding levels provides.The needed routing iinformation of physical layer at the corresponding levels can abandon to reduce the data volume of link transmission after use.
Step 203, described grouped data in the remote radio base station according to described Baotou Road by Information Selection passages at different levels.
Grouped data in the remote radio base station according to the Baotou Road by Information Selection passages at different levels, process address location until grouped data arrives purpose.So just can in the situation of various complicated networkings, simply and accurately carry out the data channel configuration.
The below illustrates technical scheme of the present invention.
