Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright it is described in further detail.
In the present invention, base station is defined by IEEE802.16e broadcast channel, Multicast Channel, transmission
Channel or the channel of multicast group, transmit control information, leads to including business control information change instruction, business
Accuse, MBS service conversation starts/terminates mark, the patten transformation of PTP Yu PTM indicates, statistics instruction,
Its MBS business is operated by terminal according to the control information received.
Illustrating first embodiment of the invention below, first embodiment of the invention relates to MBS
The control method of business, the most as shown in Figure 2.
In step 201, the MBS that base station arranges correspondence according to the needs of each MBS business controls information,
These MBS control information is sent to terminal by the channel defined by IEEE802.16e.
Wherein, the channel for transmitting control information can be IEEE802.16e definition broadcast channel,
Multicast Channel or transmission channel.If by broadcast channel transmission (such as CID=0xFFFF), then base station
Need to distribute at least one MAC layer type of message being specifically designed to transmission MBS control information, by institute
The type of message of distribution controls information at corresponding broadcast channel transmission MBS；Or base station can be passed through
The Multicast Channel of IEEE802.16e definition or transmission transmission, directly control information at higher layer transmission.
The control information sent includes that the change of MBS business control information indicates, and service announcement,
At least one in session start/end mark, the patten transformation instruction of PTP Yu PTM, statistics instruction.
Business control information change instruction: indicate whether remaining four control information of certain MBS business are sent out
Having given birth to change, be, instruction terminal re-reads and updates the control information of correspondence, and otherwise terminal need not
Read MBS again and control information.
Service announcement (Service Announce) information: comprise MBS service identification, business starts to send out
The information such as time, content identification and the relevant description sent.
The patten transformation instruction of PTM Yu PTP: instruction base station is currently by PTP or PTM mode carrying
MBS business, this mark instruction PTM carrying when base station uses PTM carrying, when base station uses PTP
During carrying, the instruction PTP carrying of this mark.In this mark by indicating PTM carrying to be converted to PTP carrying
Time, instruction terminal exits PTM pattern, sets up PTP and receive this MBS business, and vice versa.
Session start/end (Session start/stop) identify: session start or at the end of give user
Instruction information, instruction user starts receive MBS business or stop receiving this MBS business.At MBS
During business is carried out, this information indicates always and starts (start)；When, after conversation end, indicating always
Terminate (stop).
Statistics (Counting) instruction information: instruction network side needs to receive certain under idle pulley now
The number of users of individual MBS business or the number of users of all reception MBS business are added up.Terminal is receiving
After this instruction, or prepare to receive the information of this MBS business by regulation to network-feedback.This
Information can also comprise a probability threshold, for MS after receiving this instruction, by certain general
Rate initiates feedback.
Base station transmission control information while, transmit MBS service identification corresponding to this control information and
This control message length, as shown in Figure 3.Wherein, the control information transmitted can use TLV (i.e.,
The type of Type data, the length of Length data, the value of Value data) mode organize.Respectively
In control information, first base station sends business control information change instruction, and terminal determines it according to this instruction
Whether MBS business interested changes, and without changing, can no longer receive thereafter
Control information.Business control information change instruction can comprise multiple bit, the most each bit identification one
Whether MBS business control information changes, if the change instruction of this business control information comprises 8 bits,
The most at most can identify 8 MBS business.Each MBS business by Algorithm mapping on certain bit,
Such as, can be by MBS service identification mod8 (total bit number of business control information change instruction)
Value be mapped on the bit of correspondence, when MBS service identification is 17, this MBS business is corresponding
1st bit (bit starts counting up from 0) of business control information change instruction.As this MBS
When the control information of business sends change, by the 1st bit set (putting 1), otherwise that this bit is multiple
Position (setting to 0).Owing to a business control information change instruction may indicate that multiple MBS business, therefore
When transmitting this instruction, multiple MBS service identifications of correspondence can be continuously transmitted thereafter.
Subsequently enter step 202, the channel that terminal monitoring is corresponding, if interested in MBS business, then
First terminal receives the business control information change instruction comprising this MBS business, according to corresponding in instruction
Bit judge whether its MBS business interested changes, if the bit set of correspondence,
Then represent that this MBS business changes, enter step 203, otherwise then represent that this MBS business does not has
Changing, terminal no longer receives control information thereafter, direct process ends.If terminal is just moved
Move this base station range, receive business control information first, the most do not judge that this business control information becomes
Change instruction, be directly entered step 203.
In this step, if base station controls information by broadcast channel transmission, then terminal can be by monitoring
Broadcast channel specifies the message of type of message (be transmission MBS and control the type of message of information distribution),
Determine whether not receive but MBS business interested or the business of MBS business that is currently being received
Control information change instruction, if had, receive in time, without or to these MBS business the most not
Interested or do not support in ability, then ignore these message.
If base station is by Multicast Channel or transmits transmission control information, then terminal is many by monitoring this
Broadcast channel or transmit channel, directly determine whether not receive but MBS business interested or current the most just
In the business control information change instruction of the MBS business received, equally, if had, receive in time,
Without or these MBS business are all lost interest in or are not supported in ability, then ignore and received
The instruction arrived.
In step 203, terminal continues to monitor corresponding channel, according to the MBS industry after control information
Business mark, the control information receiving its MBS business interested (can receive foregoing several
One or more in control information), and enter step 204 in 207 according to the control information received
One or more.
If terminal receives MBS service announcement, and this terminal is currently needed for receiving this MBS business,
Then enter step 204, according to the MBS service identification in this service announcement, business start the time that sends,
Content identification, business associated description information add this MBS business.
If terminal receives session start/end mark, then entering step 205, terminal is according to this mark
Instruction receive or stop receiving corresponding MBS business.By this mark, terminal use need not connect
Whether continuous detection MBS-MAP message there are the data that it is to be received, and only need to inspect business control information
Change instruction, if instruction change, detects session start/end mark the most further, receives accordingly
Or stop receiving, beneficially terminal reduces power attenuation.
If terminal receives the instruction of PTP Yu PTM patten transformation, then enter step 206, terminal root
Indicate according to this patten transformation, pass through identified PTP/PTM pattern and receive corresponding MBS business.As
Really this mark is converted to PTM carrying by PTP, then terminal receives correspondence according to instruction by PTM pattern
MBS business, if this instruction by PTM be converted to PTP carrying, then can be straight for activated state terminal
Connect and receive corresponding MBS business according to instruction by PTP carrying, Idle state terminal is needed to initiate
The process exitted from idle mode, sets up the connection of PTP to receive MBS business.
If terminal receives statistics instruction, and this terminal is Idle state terminal, then enter step 207,
Idle state terminal feeds back currently received MBS business information to network side, supports that base station statistics reception refers to
Determine the number of users of MBS business.
It is noted that owing to business control information is not often change, generally change all
Unhappy, therefore these information there is no need to send in each radio frames, in the present embodiment,
The different cycles is used to be transmitted different control information.In addition to the transmission cycle, present embodiment
In also define period of change, control information is reseted according to corresponding period of change in base station.It is to say,
When control information changes, this control information is reseted in a nearest period of change in base station, and
The control information sent after this is reseted is started from a nearest transmission cycle.Wherein, period of change is more than
The transmission cycle.If terminal is initially entered base station range, need to obtain the control of corresponding MBS business
Information, then can receive control information according to the cycle of transmission；If terminal only desires to send out in MBS business
During raw change, it is updated in time, then can receive control information according to period of change.Thus ensureing eventually
While end is properly received MBS business, decreases the reception frequency of terminal, reduce the burden of terminal.
According to the change frequency of the information of control, period of change can be the several times in transmission cycle.
Second embodiment of the invention also relates to the control method of MBS business, with the first embodiment
Similar, its difference is, in the first embodiment, base station is by the channel specified, as specified
Broadcast channel, Multicast Channel or the control information of transmission transmission all MBS business；And at this
