Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
The LTE MBMS business transmitting method flow chart that Fig. 2 provides for the embodiment of the present invention, as shown in Figure 2, its concrete steps are as follows:
Step 201: the pre-defined MBMS special carrier for LTE MBMS system TDD mode, this carrier-specific is in MBMS transmission business, and defines the frame structure of this carrier wave.
The frame structure of this MBMS special carrier can be one of following two kinds:
One, this frame is only made up of special subframe and descending sub frame, and wherein, descending sub frame is only for MBMS transmission business.
Two, this frame is made up of the sub-frame of uplink of special subframe, descending sub frame and dynamically introducing, and wherein, descending sub frame is only for MBMS transmission business, and sub-frame of uplink is for transmitting the feedback information for MBMS business.The sub-frame of uplink of dynamically introducing refers to, and in the time of needs UE feedback information, just in frame structure, introduces sub-frame of uplink; In the time not needing UE feedback information, in frame structure, still only include special subframe and descending sub frame.
Tdd mode is supported two kinds of ascending-descending subframes switching point cycles, and one is 5ms, and one is 10ms.This has gone out the frame structure of the MBMS special carrier under these two kinds of ascending-descending subframes switching point cycles to table 1 respectively:
The frame structure example of MBMS special carrier when the different ascending-descending subframes switching point of table 1 cycle
As shown in table 1, the ascending-descending subframes Configuration Type number when the setting ascending-descending subframes switching point cycle is 5ms is 7, and now, except subframe 1,6 is special subframe S, other subframe is all descending sub frame D; Ascending-descending subframes Configuration Type number when the setting ascending-descending subframes switching point cycle is 10ms is 8, and now, except subframe 1 is special subframe S, other subframe is all descending sub frame D.
In two kinds of frame structures shown in table 1, all do not comprise sub-frame of uplink.In the time that needs are introduced sub-frame of uplink, the one or more descending sub frames in two kinds of frame structures shown in table 1 are replaced with to sub-frame of uplink.
It is pointed out that ascending-descending subframes Configuration Type in the embodiment of the present invention number as long as number different from the ascending-descending subframes Configuration Type having occurred in existing protocol.
Periodically broadcast away the frame structure type identification of the MBMS special carrier of the frequency of current MBMS special carrier, current use step 202:LTE base station by system broadcast message, and in the time that needs issue MBMS business, adopt frequency and the frame structure of the MBMS special carrier of current use to transmit this MBMS business.
The frame structure type identification of MBMS special carrier i.e. ascending-descending subframes Configuration Type number in table 1.
In actual applications, if desired, LTE base station also can be broadcasted away cell ID applicable MBMS special carrier by system broadcast message.
In the time of the applicable cell ID of frequency, the frame structure type identification of MBMS special carrier, the MBMS special carrier of broadcasting MBMS special carrier, LTE base station can be broadcasted away by existing system broadcast message, also can broadcast away by newly-increased system broadcast message, can only by a system broadcast message, disposable all information broadcast be gone out, also can all information be broadcasted away by multiple system broadcast message in batches.
Step 203:LTE UE receives and records the frequency of the MBMS special carrier of LTE base station broadcast, the frame structure type identification of MBMS special carrier, learn the frame structure of the MBMS special carrier of the current use in LTE base station according to the frame structure type identification of MBMS special carrier, according to this frame structure, monitor and receive MBMS business from the frequency of MBMS special carrier.
It is to be noted in addition, if the tdd mode of LTE MBMS system has only defined a kind of frame structure of MBMS special carrier, the also frame structure type identification of broadcasting MBMS special carrier not of LTE base station, because now LTE UE does not need the frame structure of MBMS special carrier to make one's options, LTE UE is receiving after the frequency of MBMS special carrier of LTE base station broadcast, directly utilizes the frame structure of unique MBMS special carrier of acquiescence on this frequency, to receive MBMS business.
In addition, in embodiments of the present invention, when frequency and/or frame structure and/or the applicable community etc. of MBMS special carrier using when LTE base station changes, LTE base station can be by system broadcast message by the new frequency of MBMS special carrier and/or new frame structure type identification and/or be newly suitable for the broadcast such as cell ID and go out.
In addition, in actual applications, some LTE MBMS systems as: in LTE R10 MBMS system can introduce uplink feedback information, in order to adapt to this situation, in the embodiment of the present invention, can adopt following solution:
One, utilize the UpPTS of the special subframe (being S subframe) in the frame structure of MBMS special carrier to transmit the uplink feedback information of UE.
Two, in the frame structure of MBMS special carrier, dynamically introduce sub-frame of uplink (being U subframe) and transmit the uplink feedback information of UE.
Now, in the time of needs LTE UE feedback information, LTE base station shifts to an earlier date sending system broadcast, this message is carried the configuration information of the U subframe that can be used for feeding back uplink information, for example: the positional information of U subframe in MBMS special carrier, this positional information comprises: the subframe position of U subframe in the frame structure of MBMS special carrier, and/or the appearance cycle of U subframe in MBMS special carrier
LTE UE receives after this system broadcast message, learns the configuration information of U subframe, in the time that this U subframe occurs, by this U subframe to LTE base station feedback uplink information.
In the time that the configuration information of U subframe changes, LTE base station will send the configuration information of the U subframe after changing by system broadcast message.
In actual applications, delivery time that can pre-specified MBMS special carrier Notification of Changes message, or issue in advance the delivery time of MBMS special carrier Notification of Changes message by system broadcast message, this Notification of Changes message-specific is in the change information that sends MBMS special carrier, as one or combination in any in the frequency of: the MBMS special carrier after variation, frame structure, applicable cell ID and the configuration information of U subframe in MBMS special carrier.LTE UE initiatively goes to obtain this message at the delivery time of MBMS special carrier Notification of Changes message, thereby learns the change information of MBMS special carrier; Also can cancel existing page notification message, but change into and send MBMS special carrier Notification of Changes message at the delivery time of this existing page notification message.
The composition schematic diagram of the LTE base station that Fig. 3 provides for the embodiment of the present invention, as shown in Figure 3, it mainly comprises: signaling broadcast module 31 and MBMS transport module 32, wherein:
Signaling broadcast module 31: periodically the frequency of the MBMS special carrier of tdd mode is carried in system broadcast message and is broadcasted away, and this frequency is sent to MBMS transport module 32.
MBMS transport module 32: the frequency of the MBMS special carrier that reception signaling broadcast module 31 is sent, in the time that needs issue MBMS, on this frequency, transmit this MBMS according to the frame structure of the MBMS special carrier of the tdd mode of definition, this MBMS special carrier is exclusively used in MBMS transmission, and the frame structure of this carrier wave is: be only made up of special subframe and descending sub frame, or, formed by the sub-frame of uplink of special subframe, descending sub frame and dynamically introducing.
In the time that the frame structure of two or more MBMS special carriers is supported in LTE base station simultaneously, signaling broadcast module 31 is further used for, periodically the frame structure type identification of MBMS special carrier is carried in system broadcast message and is broadcasted away, this frame structure type identification is sent to MBMS transport module 32, so that MBMS transport module 32 is determined the frame structure of current use according to this frame structure type identification simultaneously.
