Embodiment
Basic thought of the present invention is: send multicast-zone position information on broadcast channel, and multicast-zone position information divides three grades of descriptions, comprise superframe level position information, frame level position information and sub-frame level positional information.So, just can determine the position at multicast resource place, thereby the multicast resource is carried out flexible allocation according to the indication on the broadcast channel.
Here, the transmission of multicast-zone position information generally is to send at interval, and transmission time interval is a N superframe, and N can be a fixed value, also can be changing value.That is to say that the positional information in multicast zone can send by fixed intervals, also can send by change interval.
Wherein, described broadcast channel can be auxiliary superframe head (S-SFH) or sub-broadcast channel (SBCH) or main broadcast channel.Described superframe level position can be determined or determine with side-play amount and quantity with bitmap; Described frame level position can be determined or determine with the multicast number of frames with bitmap; Described sub-frame level position can be determined or determine with multicast subframe quantity with bitmap.
Further, can also indicate whether send multicast-zone position information in broadcast channel, if the multicast zone is arranged in the multicast-zone position information transmission time interval, then indication has the multicast zone, and sends the positional information in multicast zone; If no, then indicate no multicast zone.
Further, whether can also indicate multicast-zone position information to change in broadcast channel, variation described here is meant: whether current multicast-zone position information changes for the multicast-zone position information that sends on the inherent broadcast channel of previous multicast-zone position information transmission time interval.
Among the present invention once specifically how superframe level position information, frame level position information, sub-frame level positional information are described respectively below, and their send modes separately.
For superframe level position information, can adopt bitmap to represent; Also can adopt offset X and quantity Y to represent:
When superframe level position information adopted bitmap to represent, the superframe bitmap comprised N bit, N superframe of N the corresponding multicast-zone position information transmission time interval of bit difference, and bit is 1 o'clock in the bitmap, in the superframe of expression correspondence the multicast zone is arranged; Bit is 0 o'clock, does not have the multicast zone in the superframe of expression correspondence.This superframe bitmap sends in broadcast channel.
Wherein, described superframe bitmap can not distinguished multicast area (MBS ZONE), also can distinguish MBS ZONE.For same MBS ZONE, the multicast service that all base stations send is identical, and a plurality of MBS ZONE can be supported in a base station.For the base station of supporting L MBS ZONE, when not distinguishing MBS ZONE, the base station is propped up and is only sent a N bit superframe bitmap; When distinguishing MBS ZONE, the base station will send corresponding L N bit superframe bitmap.
When superframe level position information adopted offset X and two kinds of parameters of quantity Y to represent, offset X was meant the superframe quantity with respect to the superframe that sends current superframe level position information; Accordingly, the superframe position that comprises the multicast zone is meant and begins a continuous Y superframe from the position that offset X indicates.Such as: the superframe that sends superframe level position information is second superframe, and offset X is 3, and quantity Y is 2, and just expression comprises the superframe position in multicast zone in continuous two superframes of the 5th superframe as original position.
In the multicast-zone position information transmission time interval, can represent the position in its multicast zone to each MBS ZONE with the parameter that an offset X adds a quantity Y; The position that also can represent its multicast zone with the parameter that a plurality of offset X are added a quantity Y; Accordingly, just send a side-play amount and a quantity during transmission, or send a plurality of side-play amounts and a plurality of quantity.For L multicast area, can send a side-play amount and L quantity, and the multicast in each multicast area zone continuous distribution, wherein, side-play amount is the start offset amount in the multicast zone in all-multicast area, L quantity is corresponding L multicast area respectively, the identifier sequence consensus in the order of L quantity and L multicast area.
Superframe level position information can also represent that wherein, Hyper Frame Number Z is the original position that comprises the superframe in multicast zone with Hyper Frame Number Z and two kinds of parameters of quantity Y, and quantity Y represents that beginning a continuous Y superframe from indicated original position all comprises the multicast zone.
Under this mode, in the multicast-zone position information transmission time interval, can represent the position in its multicast zone to each MBS ZONE with the parameter that a Hyper Frame Number Z adds a quantity Y; The position that also can represent its multicast zone with the parameter that a plurality of Hyper Frame Number Z add a quantity Y; Accordingly, just send a Hyper Frame Number and a quantity during transmission, or send a plurality of Hyper Frame Number and a plurality of quantity.For L multicast area, can send a Hyper Frame Number and L quantity, and the multicast in each multicast area zone continuous distribution, wherein, Hyper Frame Number is the initial Hyper Frame Number in the multicast zone in all-multicast area, L quantity is corresponding L multicast area respectively, the identifier sequence consensus in the order of L quantity and L multicast area.
For frame level position information, can adopt bitmap to represent, or adopt multicast number of frames P to represent:
When frame level position information adopted bitmap to represent, the frame number that comprises in the bit number that framing bit figure comprises and the superframe was corresponding, such as: a superframe has 4 frames, and the framing bit figure of correspondence accounts for 4 bits.Bit is 1 o'clock, in the frame of expression correspondence multicast subframe is arranged; Bit is 0 o'clock, does not have multicast subframe in the frame of expression correspondence.
Concrete, the transmission of framing bit figure information has following several form:
First kind, in N superframe of multicast-zone position information transmission time interval, framing bit figure has M, and bit is 1 M superframe in the corresponding respectively superframe bitmap, and a corresponding M framing bit figure sends.
Second kind, in the M that includes a multicast zone superframe, indicate the framing bit figure of this superframe whether identical to each superframe, and then indicate whether to send its framing bit figure with the framing bit figure of previous superframe.Can be that indication sends and comprise the framing bit figure of current superframe at the framing bit figure of the framing bit figure of current superframe and previous superframe not simultaneously; When identical, indication does not send the framing bit figure of current superframe.If include in M the superframe in multicast zone, the framing bit figure of each superframe correspondence is identical, can only send the framing bit figure of one 4 bit on broadcast channel.Under this form, described superframe all refers to contain the superframe in multicast zone.
That is to say, in the multicast-zone position information transmission time interval, if the multicast frame position information of each multicast superframe is different, then send all the framing bit figure in the multicast-zone position information transmission time interval, whether the framing bit figure that perhaps indicates current multicast superframe is identical with the framing bit figure of previous multicast superframe and at the framing bit figure that does not send current multicast superframe simultaneously; If the multicast frame position information of each multicast superframe is identical, then send a framing bit figure.
When frame level position information was represented with multicast number of frames P, the P value was 1～4, showed in this superframe that every frame all comprises multicast subframe since the first frame continuous P frame, and P can represent with two bits; Can show also in this superframe that every frame all comprises multicast subframe in the last continuous P frame, P can represent with two bits.That is to say that the multicast frame is continuous distribution in corresponding multicast superframe, can be the frame of foremost several successive, or be the frame of several successive backmost.
Concrete, the transmission of multicast number of frames information has following several form:
First kind of form, in N superframe of multicast-zone position information transmission time interval, bit is 1 M superframe in the corresponding superframe bitmap, and each superframe all sends corresponding multicast number of frames P, and the P value of each superframe correspondence is identical or different.
Second kind of form in the M that includes a multicast zone superframe, indicates whether to send its multicast number of frames to each superframe.Can be that indication sends and comprise the multicast number of frames of this superframe in the multicast number of frames of the multicast number of frames of current superframe and previous superframe not simultaneously; When identical, indication does not send the multicast number of frames of this superframe.If include in M the superframe in multicast zone, the multicast number of frames P value of each superframe correspondence is identical, can only send a multicast number of frames P on broadcast channel.Under this form, described superframe all refers to contain the superframe in multicast zone.
For the sub-frame level positional information, can adopt bitmap to represent, or adopt multicast subframe quantity n to represent:
When the sub-frame level positional information adopted bitmap to represent, the subframe bitmap was a m bit, m descending sub frame in the corresponding unit frame.Bit is 1 o'clock, represents that this subframe is a multicast subframe; Bit is 0 o'clock, represents that this subframe is not a multicast subframe.
When the sub-frame level positional information was represented with multicast subframe quantity n, the n value was 1 to m, shows multicast subframe continuous distribution in corresponding multicast superframe, and last n descending sub frame continuously all is multicast subframe in this frame.
For different frame in the superframe, if comprise multicast subframe, its subframe position information is all identical.That is to say that in same superframe, each multicast subframe pattern that comprises in the frame of multicast subframe is identical.
Concrete, the transmission of sub-frame level positional information has following several form:
First kind of form, in N superframe of multicast-zone position information transmission time interval, sub-frame level positional information (multicast subframe bitmap or multicast subframe quantity) has M, corresponding respectively M the superframe that comprises the multicast zone, and a corresponding M multicast subframe bitmap or multicast subframe quantity all send.
Second kind of form in the M that includes a multicast zone superframe, indicates whether to send its multicast subframe bitmap or multicast subframe quantity to each superframe.Can be not simultaneously in the multicast subframe positional information of the multicast subframe positional information of current multicast superframe and previous multicast superframe, indication sends and comprises the multicast subframe bitmap or the multicast subframe quantity of current multicast superframe; When identical, indication does not send the multicast subframe bitmap or the multicast subframe quantity of current multicast superframe.If include in M the superframe in multicast zone, the multicast subframe positional information of each superframe correspondence is all identical, can only send a multicast subframe bitmap or multicast subframe quantity on broadcast channel.
That is to say, in the multicast-zone position information transmission time interval, if the multicast subframe positional information of each multicast superframe is different, then send all subframe bitmaps or multicast subframe quantity in the multicast-zone position information transmission time interval, perhaps only send with respect to vicissitudinous subframe bitmap of previous multicast superframe or multicast subframe quantity; If the multicast subframe positional information of each multicast superframe is identical, then send a sub-framing bit figure or multicast subframe quantity.
Can a M bit map be set to M the superframe that includes the multicast zone, M multicast superframe in the corresponding multicast-zone position information transmission time interval, the M bit map represents whether to send corresponding multicast frame level position information and multicast subframe level position information.In the M bit map, bit is 1 o'clock, the multicast pattern (comprising multicast frame and multicast subframe positional information) of representing the corresponding multicast superframe in the current multicast-zone position information transmission time interval, different with the multicast pattern of corresponding multicast superframe in the previous multicast-zone position information transmission time interval, therefore indication will send the multicast frame position information and the multicast subframe positional information of correspondence on broadcast channel; Bit is 0 o'clock, the multicast pattern of the corresponding multicast superframe in the multicast pattern of representing the corresponding multicast superframe in the current multicast-zone position information transmission time interval and the previous multicast-zone position information transmission time interval is identical, therefore indicates and does not send this multicast frame position information and multicast subframe positional information.
Described frame level position information and sub-frame level positional information can also be represented by call number that a kind of combination of corresponding frame level position information of each call number and sub-frame level positional information is described, the combination that the different index correspondence is different is described.So, the described multicast-zone position information that sends on broadcast channel is exactly: send the call number that institute's frame level position information of using and sub-frame level positional information make up correspondence.
