Embodiment
At problems of the prior art, the professional indication information sending method of a kind of E-MBS is proposed among the present invention, be about to the professional indication information of E-MBS and be carried in the superframe head, send to terminal.Specifically, the professional indication information of this E-MBS is to send to base station in the E-MBS Service coverage by the E-MBS server, then, sends to terminal by the base station again.In addition, the professional indication information of described E-MBS mainly comprises: whether exist in the superframe whether exist in E-MBS business, the superframe E-MBS MAP, E-MBS business and unicast service be carry out with frequency division multiplexing (FDM) mode or Time Division Multiplexing mode multiplexing, and information such as E-MBS business region occupied.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of the inventive method embodiment.As shown in Figure 1, may further comprise the steps:
Step 11:E-MBS server sends to base station in the E-MBS Service coverage with the professional indication information of E-MBS; And, further send E-MBS MAP and E-MBS data to the base station when indication exists E-MBS professional in the professional indication information of E-MBS.
In actual applications, the professional indication information of E-MBS can send simultaneously with E-MBS MAP and E-MBS data, also can separately send.Concrete send mode is known in this field, repeats no more.
Step 12: the base station receives the professional indication information from the E-MBS of E-MBS server, and the professional indication information of this E-MBS is carried in the superframe head, sends to terminal; In addition, as if the E-MBS MAP and the E-MBS data that receive from the E-MBS server, then the base station further sends to terminal with E-MBS MAP and E-MBS data.
In this step, can carry the professional indication information of E-MBS in the superframe head by some indicating bits are set.Provide several concrete set-up modes below:
Mode one:
E-MBS traffic indicator bit, E-MBS MAP indicating bit, E-MBS multiplex mode indicating bit and E-MBS zone indicating bit are set in the superframe head.
The E-MBS traffic indicator bit by the different values that are set to be scheduled to, indicates whether there is the E-MBS business in the superframe; Such as, if this indicating bit is set to 1, then there is the E-MBS business in expression, if be set to 0, then there is not the E-MBS business in expression; Certainly, also can represent to exist the E-MBS business with 0, represent not exist the E-MBS business with 1, follow-up analogue repeats no more.
Only under the prerequisite that has the E-MBS business, E-MBS MAP indicating bit, E-MBS multiplex mode indicating bit and E-MBS zone indicating bit just can exist.Wherein:
E-MBS MAP indicating bit by the different values that are set to be scheduled to, indicates whether there is E-MBS MAP in the superframe; Such as, if this indicating bit is set to 1, then there is E-MBS MAP in expression, if be set to 0, then there is not E-MBS MAP in expression.
E-MBS multiplex mode indicating bit by the different values that are set to be scheduled to, is indicated the multiplex mode of E-MBS business and unicast service; Such as, if this indicating bit is set to 1, then the TDM mode is adopted in expression, if be set to 0, then the FDM mode is adopted in expression.
E-MBS zone indicating bit by the different values that are set to be scheduled to, is indicated the professional region occupied of E-MBS, and this indicating bit is relevant with being provided with of E-MBS multiplex mode indicating bit; If it is multiplexing that E-MBS business and unicast service adopt the TDM mode to carry out, then this indicating bit is used to represent which subframe is the E-MBS business taken, if adopt the FDM mode, then this indicating bit is used to represent which frequency resource is the E-MBS business taken.
Usually, availablely in the subframe have 4 frequency bands, be respectively zero frequency band (FP0), first frequency band (FP1), second frequency band (FP2) and the 3rd frequency band (FP3).In the present embodiment, the frequency resource that can indicate the E-MBS business to take in such a way: take which continuous dispensing Resource Unit (CRU) among the FP0 of each subframe, take FP1, FP2 and FP3 in which subframe, perhaps, take FP1, FP2 or FP3 in which subframe.
Mode two:
The multiplexing combined coding indicating bit of E-MBS MAP indicating bit and E-MBS is set in the superframe head.
E-MBS MAP indicating bit by the different values that are set to be scheduled to, indicates whether there is E-MBS MAP in the superframe; Such as, if this indicating bit is set to 1, then there is E-MBS MAP in expression, if be set to 0, then there is not E-MBS MAP in expression.
The multiplexing combined coding indicating bit of E-MBS, by the different values that are set to be scheduled to, indicate whether to have the E-MBS business in the superframe, and under the situation that has the E-MBS business, further indicate the multiplex mode and the professional region occupied of E-MBS of E-MBS business and unicast service; Such as, if this indicating bit is set to 0 (binary coding 0b000), then there is not the E-MBS business in expression, correspondingly, E-MBS MAP indicating bit then needs to be set to 0; If the multiplexing combined coding indicating bit of E-MBS is set to the value between binary coding 0b001～0b011, then there is the E-MBS business in expression, and E-MBS multiplex mode professional and unicast service is the TDM mode, and the difference of value is represented the difference of the subframe that the E-MBS business takies; If the multiplexing combined coding indicating bit of E-MBS is set to the value between binary coding 0b100～0b111, then there is the E-MBS business in expression, and E-MBS multiplex mode professional and unicast service is the FDM mode, the difference of value is represented the difference of the CRU among the FP0 that the E-MBS business takies, perhaps, take the different of FP1, FP2 in which subframe and FP3, again or, take FP1, FP2 in which subframe or the difference of FP3.
Need to prove that in aforesaid way one and the mode two, the figure place of each indicating bit can be provided with arbitrarily as required, but in order to pare down expenses, what be provided with usually is short more good more.
In this step, terminal is given with the superframe hair after setting the professional indication information of E-MBS according to above-mentioned arbitrary mode in the superframe head in the base station; In addition, if received E-MBSMAP and E-MBS data, then further E-MBS MAP and E-MBS data are sent to terminal from the E-MBS server.Usually, send the professional indication information of E-MBS earlier, and then send E-MBS MAP and E-MBS data.E-MBS MAP and E-MBS data carry are in the appointed area in superframe, in the professional region occupied of promptly described E-MBS.
Step 13: terminal parses the professional indication information of E-MBS from the superframe head, determines whether there is the E-MBS business in the superframe according to the professional indication information of this E-MBS, if there is no, and process ends then; If exist, then in the professional region occupied of E-MBS, find E-MBSMAP, and then in the professional region occupied of E-MBS, receive and resolve the E-MBS data according to E-MBS MAP according to the professional indication information of E-MBS.
In this step, terminal parses the E-MBS traffic indicator bit from the superframe head, determine whether to exist the E-MBS business according to its value, such as, if the E-MBS traffic indicator bit is set to 0, then there is not the E-MBS business in expression, if be set to 1, then there is the E-MBS business in expression.If there is no E-MBS business, then process ends is not promptly carried out other and the professional relevant processing of E-MBS; If there is the E-MBS business, then at first find E-MBS MAP, in the professional region occupied of E-MBS, receive and resolve the E-MBS data according to E-MBS MAP then.
