Cell broadcaste service is the business that the message that some are brief is broadcasted in the appointed area, and this zone can be one or a plurality of sub-district, also can be the All Ranges that whole PLMN (Public Land Mobile Nerwork) covers.Wherein, be separate between each CBS (cell broadcaste service) message.CBS message is produced by CBE (Cell Broadcast Entity), these Cell Broadcast Entities are pooled to CBC with CBS message, CBC is issued corresponding sub-district with these CBS message and is broadcasted according to the coverage tabulation that Cell Broadcast Entity sends.Transmission repeated broadcast blanking time that CBS message provides according to CBC.The content difference of CBS message sends also different with the number of repetition of broadcasting at interval.Present transfer approach is:
1, CBC (CBC) is by SABP (service area Radio Broadcasting Agreements), and the CBS message that will send is issued RNC (wireless network control) part of UTRAN (universal land radio access web).The parameter of issuing RNC simultaneously also has the parameters such as transmission interval, repeated broadcast number of times and service area tabulation of this CBS message.
2, all there is a BMC (broadcast multi-broadcasting control module) each sub-district under the RNC administration in RNC inside.After RNC receives that CBS message that CBC sends and message send parameters such as interval, repeated broadcast number of times, service area tabulation, according to the service area list parameter CBS message and message send the interval, the repeated broadcast number of times sends to corresponding BMC.
3, after BMC received CBS message and relevant parameter, the CBS message that storage receives was pressed
3, after BMC receives CBS message and relevant parameter, the CBS message that storage receives, the method that the air interface parameters decision that traffic carrying capacity of measuring according to BMC and Radio Resource control section provide sends and generate schedule information in the band, every CBS message is passed to RLC (Radio Link control) layer according to sending at interval with the repeated broadcast number of times and the interior schedule information of band that require, rlc layer is cut apart these through the message that repeats and dispatch after, send MAC (medium access control) layer again to and form transmission block, all working in this step is all finished in RNC.
4, RNC will come from the transmission block of each BMC, and the user's face by Iub (interface between RNC and the wireless base station) sends the respective cell among the NodeB (wireless base station) to.At this moment be fully independently between each sub-district among the NodeB,, also will on Iub interface, transmit repeatedly even same CBS message will send a plurality of sub-districts among the same NodeB to.
5, the respective cell among the NodeB is mapped to it on corresponding SCCPCH (Secondary Common Control Physical Channel) physical frame after receiving transmission block, broadcasts in whole cell range.
Adopt above-mentioned CBS message transfer method, even require the CBS message of broadcasting not change, be RNC with the interface of CBC on do not receive any message, originally the CBS message that scheduling is good still need repeat to transmit on Iub interface: and same CBS message is will send to different districts under the same NodeB administration time, this CBS message also must send repeatedly on Iub interface, expends the resource of Iub interface in a large number.
