Abstract
The invention relates to a system and a method for acquiring integrated movable broadcasting support capability of a base station. The method comprises the step that; before a cell for transmitting integrated movable broadcasting (IMB) is established, a wireless network controller acquires the IMB support capability of the base station through signaling interaction. By adopting the technical scheme of the invention, the problems that interfaces are not matched when the wireless network controller acquires IMB support capability information of a local cell of the base station and the IMB support capability information of the local cell of the base station cannot be acquired immediately in the prior art.
Description
Technical field
The invention belongs to communication technical field.More particularly, the present invention relates to a kind of system and method that obtains integrated movable broadcasting support capability of base station.
Background technology
Along with being extensive use of and the rapid growth of mobile communication subscriber quantity of the fast development of mobile communication technology, mobile communications network, in mobile communications network, realize MBMS (MultimediaBroadcastand Multicast Service, broadcast multi-broadcasting is served), become one of focus of mobile communication system development.
3GPP (Third Generation Partnership Project, third generation partner program) R7 protocol version has defined MBSFN (MBMS single Frequency Network, MBMS single frequency network) technical specification.As the MBMS technology that strengthens, the wireless signal that all adjacent base station synchronized transmissions are identical, UE can be considered as multipath signal with the signal that comes from different base station, has improved the availability of frequency spectrum greatly.
3GPP R8 protocol version is introduced IMB (Integrated MobileBroadcast, integrated mobile broadcast) technology again in MBSFN, the structural model figure of IMB operation system as shown in Figure 1.In the 3G network of having built well, integrated mobile broadcast service at lower cost efficiently realizes multimedia broadcasting functions such as mobile network's video broadcasting.
According to the 3GPP existing protocol, NodeB (base station also claims Node B) can not report the IMB tenability of NodeB home cell to RNC (RadioNetwork Controller, radio network controller), and RNC can't know whether the home cell of NodeB supports IMB.RNC issues the sub-district of IMB and sets up request, if the NodeB home cell is not supported IMB, then can not set up the T-CPICH (Time-multiplexed Common Pilot Channel, time division common pilot channel) that supports the IMB ability.Because the sub-district is set up demand signalling and be there is no the indication of clear and definite field and require to set up the T-CPICH channel, NodeB still can report the RNC sub-district to set up successfully, causes the processing of NodeB and RNC inconsistent.RNC continues to issue Common transport channel and sets up request, when requiring the parameters such as Sub-frame number of configuration 3.84Mcps MBSFN IMB, NodeB just can be owing to home cell is not supported IMB, report the RNC Common transport channel to set up failure, former because: TNBAP_requested_configuration_not_supported.If RNC can know issuing before the sub-district sets up whether the home cell of NodeB has the IMB tenability, just can avoid the sub-district of IMB to set up redundant processes such as unusual, Common transport channel foundation failure.
Usually RNC can obtain the IMB tenability of NodeB home cell by the backstage configuration mode.But it is loaded down with trivial details that this method realizes, and tend to exist the Iub mouth butt joint problem of the RNC of different vendor, NodeB.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of system and method that obtains integrated movable broadcasting support capability of base station, the problem that interface does not match and can't obtain the IMB tenability information of NodeB home cell immediately in the time of can effectively solving RNC in the prior art and obtain the IMB tenability information of NodeB home cell.
In order to address the above problem, the invention provides a kind of method of obtaining integrated movable broadcasting support capability of base station, comprising:

Further, the mode that described RNC obtains the IMB tenability of base station is, when the IMB of base station home cell tenability changed, the base station reported the resource status Indication message to RNC, included the IMB tenability information of base station home cell in the described resource status Indication message.
Further, described RNC periodically sends described audit request information.
Further, described base station comprises the base station home cell in the audit response message IMB tenability information is meant, the base station increases the cell of expression IMB tenability, the IMB tenability information of carrying the base station home cell in this cell in the audit response message.
Further, described base station comprises the base station home cell in the resource status Indication message IMB tenability information is meant, the base station increases the cell of expression IMB tenability, the IMB tenability information of carrying the base station home cell in this cell in the resource status Indication message.
Also a kind of system that obtains integrated movable broadcasting support capability of base station of the present invention comprises radio network controller (RNC) and base station;
Described RNC is used to issue before the sub-district foundation of integrated mobile broadcast (IMB), by obtaining the IMB tenability of described base station with the base station Signalling exchange.
Further, the IMB tenability that described RNC obtains the base station is meant, RNC sends audit request information to the base station, and the audit response message is returned to RNC after receiving audit request information in described base station, includes the IMB tenability information of NodeB home cell in the described audit response message.
Further, the IMB tenability that described RNC obtains the base station is meant, when the IMB of base station home cell tenability changed, described base station reported the resource status Indication message to RNC, included the IMB tenability information of base station home cell in the described resource status Indication message.
Further, described RNC periodically sends described audit request information.
Further, described base station comprises the base station home cell in the audit response message IMB tenability information is meant, the base station increases the cell of expression IMB tenability, the IMB tenability information of carrying the base station home cell in this cell in the audit response message.
Further, described base station comprises the base station home cell in the resource status Indication message IMB tenability information is meant, the base station increases the cell of expression IMB tenability, the IMB tenability information of carrying the base station home cell in this cell in the resource status Indication message.
In sum, adopt technical scheme of the present invention, RNC can obtain the IMB tenability information of NodeB home cell by Signalling exchange, compare the mode of obtaining the IMB tenability of NodeB home cell by the backstage configuration mode, can avoid the RNC and the unmatched problem of the interface between NodeB of different vendor, in addition, adopt technical scheme of the present invention, RNC can also obtain the IMB tenability change information of NodeB home cell real-time and accurately.
