Description
Technical field
The present invention relates to the communications field, particularly relate to the method for notice MCCH message alteration, base station and terminal.
Background technology
As the new generation of wireless communication technology, LTE (Long Term Evolution research project) the hope higher data throughout of realization that 3GPP (third generation partner program) is leading and better network performance.In order to effectively utilize mobile network resource, 3GPP proposes MBMS (MultimediaBroadcastMulticastService, multimedia broadcast multi-broadcasting business).Because multimedia video information both can be broadcasted directly to all users by MBMS, one group of contracted user charged also can be sent to watch.Therefore MBMS can help operator to carry out multimedia advertising, the free and multiple business application such as pay-television channels, multimedia message mass-sending.
At present, MBMS both can be sent by normal cells, also can be sent by carrier cell dedicated.In normal cells, system message is periodic broadcast, and can only could change system message at some time point, and these time points are called as " amendment cycle boundary ".Fig. 1 is the transmission schematic diagram of system message in the normal cells of prior art.In Fig. 1, system message repeats to send within each amendment cycle, and the amendment cycle is the integral multiple of repetition period.When system message changes, eNB (E-UTRANNodeB, evolved base station) will carry the previous amendment cycle, by beep-page message notification terminal.Terminal, after knowing that system message will change, reads the system message after changing when the next one amendment cycle.
Use special carrier to send MBMS and can utilize Radio Resource more efficiently, cover larger scope.Therefore use special carrier to send MBMS and effectively can save interface-free resources, improve resource utilization.Different from general community, carrier cell dedicated only have downlink resource, do not have corresponding ascending resource.And carrier cell dedicated not have terminal resident, also would not have the expense such as paging, system message broadcast.In order to reach the object of efficiency utilization interface-free resources, MIB (MasterInformationBlock is only had in carrier cell dedicated, Master Information Block), MCCH (MulticastControlChannel, multiparty control channel) message and MBMS data.Wherein, the time location of MIB and frequency location are all fixing; The time location of MCCH message is fixing, and frequency location then may not be fixed.
Fig. 2 is the carrier cell dedicated middle MCCH transmission of messages schematic diagram of prior art.The mode that MCCH message revises cycle and MCCH repetition period with MCCH is transmitted.Within the MCCH amendment cycle, MCCH message is constant, and in order to the reliable reception that ensures MCCH message and can receive MCCH message as soon as possible to ensure newly to access terminal, MCCH message retransmitted with the MCCH repetition period.Because MCCH message is constant within the MCCH amendment cycle, therefore user terminal there is no need all to go reception one not have vicissitudinous MCCH message at every turn, but only receives the MCCH message changed.But do not have beep-page message in carrier cell dedicated, therefore when MCCH message changes, notification terminal just cannot be carried out by beep-page message in base station.In order to solve this kind of problem, prior art mainly adopts following three kinds of schemes.
(1) UE (terminal) reads MCCH message in each MCCH amendment cycle, and no matter whether MCCH message changes.
This kind of method needs UE to read MCCH message within each MCCH amendment cycle, and the frequency changed due to MCCH message is very low, therefore will cause meaningless power consumption.
(2) in MIB, comprise a parameter, be used to indicate MCCH and whether change.If eNB determines to change MCCH, just carry previous MCCH and revise periodic notification MIB instruction.UE then will read MIB within each MCCH amendment cycle, to know whether MCCH changes.If find that MCCH changes, then revise cycle section start from next MCCH and read the MCCH message changed.
The frequency changed due to MCCH is very low, and therefore UE reads MIB within each MCCH amendment cycle, can cause meaningless power consumption.
(3) before the MCCH of special carrier changes, network, sending beep-page message with in the one or more normal cells covered, will change with notification terminal MCCH message.This terminal is paging receiving from oneself resident community then, knows that this MCCH message will change.If the business of terminal to this special carrier is interested, then it revises at next MCCH the MCCH message that cycle boundary reads change again.
This kind of method needs to modify to beep-page message, to increase a kind of paging reason---and the MCCH of special carrier changes.In addition, this method need by with the normal cells covered and carrier cell dedicated between associate, also need to increase the interbehavior between some eNB (evolved base station).When carrier cell dedicated MCCH changes, the normal cells that notice is relevant is needed to generate paging.
To sum up, how to notify and how to read MCCH message change in technology existing, or terminal power consumption amount can be made excessive, or need normal cells to associate with carrier cell dedicated.

In step 610, eNB generates radio frames; Wherein, Physical Downlink Control Channel (physicaldownlinkcontrolchannel in this radio frames in MIB subframe, PDCCH) first row at place and/or secondary series OFDM symbol carry multiple bit information, the plurality of bit information is for notifying the change of MCCH message and MIB.This wireless frame structure concrete will be described in detail by Fig. 8 and respective description part.
In an embodiment, in this eNB (or part) MIB subframe within an amendment cycle of MCCH, as in the MIB place subframe (last the MIB place subframe in the MCCH amendment cycle namely before this MCCH amendment cycle) before MCCH amendment cycle boundary, select first row and/or the secondary series OFDM symbol at PDCCH place, notify the change of MCCH message and MIB with the multiple bit informations by this OFDM symbol is transmitted
In one embodiment of the invention, multiple bit informations that above-mentioned OFDM symbol is transmitted are dibit information, and this dibit information has four kinds of combinations, is respectively:
If value is 00, represent that MIB changes, UE needs to read MIB that is that upgrade or that change;
If value is 01, represent that MCCH message changes, UE needs to read MCCH message that is that upgrade or that change;
If value is 10, represent that MIB and MCCH message all changes, UE needs to read MIB and MCCH message that is that upgrade or that change;
Value 11 is retentions.
It should be noted that, above-mentioned four kinds of combinations are only examples, and as 00 change that also can represent MCCH message, 01 change that also can represent MIB, such example is a lot, does not repeat them here.
In addition, the present invention is also not limited to the change being come joint instructions MIB and MCCH message by above-mentioned dibit information.Also can be indicated the change of MIB, MCCH message respectively by this dibit information, namely indicated the change of MIB by one of them bit information, another bit information indicates the change of MCCH message.The compound mode that this kind indicates respectively also has multiple, also repeats no more at this.
In step 620, the radio frames that eNB generates to carrier cell dedicated forwarding step 610 in the mode of broadcast group broadcast, and in this radio frames, comprise the information changed by OFDM symbol instruction MIB and MCCH.
Fig. 7 is the method flow diagram of the acquisition MCCH message alteration of another embodiment of the present invention.
