Description
Technical field
The present invention relates to LTE (Long Term Evolution, Long Term Evolution) system, particularly relate in the method for multimedia broadcast-multicast service Single Frequency Network (MBSFN, Multimedia Broadcast multicastservice Single Frequency Network) areas accept multicast control channel MCCH (MulticastControl Channel) information and receiving system.
Background technology
Along with the fast development of the Internet and the universal of large-screen multi-functional mobile phone, a large amount of Mobile data multimedia service and various high bandwidth multimedia service are there is, such as: video conference, television broadcasting, video request program, video ads, online education, interactive game etc., not only meet the business demand that mobile subscriber constantly rises, simultaneously also for mobile operator brings new business growth point.The multiple user of these Mobile data multimedia service requirements can receive identical data simultaneously, compared with general data service, has the features such as data volume is large, duration length, delay sensitive.
In order to effectively utilize mobile network resource, third generation partner program (3rd GenerationPartnership Project, referred to as 3GPP) propose MBMS (Multimedia BroadcastMulticast Service, multimedia broadcast-multicast service) business, this MBMS is a kind of technology transmitting data from a data source to multiple target, achieve sharing of network (comprising core net and Access Network) resource, improve the utilance of Internet resources (especially air interface resource).The MBMS of 3GPP definition can not only realize classes of messages multicast and the broadcast of plain text low rate, broadcast and the multicast of high-speed multimedia service can also be realized, multiple abundant video, audio frequency and multimedia service are provided, this has complied with the trend of following Mobile data development undoubtedly, for the development of 3G (3rd Generation, third generation digital communication) provides better business prospect.
At present, in LTE (Long Term Evolution, Long Term Evolution) R9 system, MBMS is introduced.MBMS carries in systems in which and needs the common transport of control signal and user data to realize.Wherein, control signal will inform the corresponding controling parameters of terminal (such as receiving terminal, user equipment (UE) (UserEquipment)), guides terminal to go to corresponding position to receive its interested MBMS (i.e. corresponding user data).This control signal is undertaken transmitting by MCCH (Multicast Control Channel, multicast control channel) in LTE R9 system.
MBMS is with multimedia broadcast-multicast service Single Frequency Network (MBSFN, MultimediaBroadcast multicast service Single Frequency Network) region and MBSFN Area carry out Region dividing, wherein MBSFN Area is made up of a series of community, community in MBSFN Area send control signaling and user data time multimedia broadcast-multicast service Single Frequency Network MBSFN technology will be used to carry out synchronized transmission, make UE (User Equipment, subscriber equipment) can obtain merge gain accordingly when receiving.A certain specific cell may simultaneously cover by multiple MBSFNArea, Here it is, and usually said MBSFN Area overlap covers (overlapping), and at present, community supports that the overlap of 1 to 8 MBSFN Area covers.
When a certain community exists overlapping coverage condition, it just may have multiple MCCH (because each MBSFN Area is a corresponding MCCH) simultaneously; For each specific MCCH, all there is MCCH MP (Modification Period revises the cycle), and in MCCH MP, the content that MCCH carries does not allow to occur to change; In MCCH MP, the carrying out of repeating also sends by MCCH information, the time interval wherein sent is referred to as MCCH RP (Repeat Period repetition period), carries out repeating to send the reliability mainly receiving MCCH information in order to improve UE with the repetition period.
The amendment cycle MP of MCCH and the relation of repetition period RP are as shown in Figure 1, in MCCH MP (n), the content that MCCH sends can not change, and can only arrive next MCCH MP place and just may change, and what MCCH RP illustrated in MCCH MP MCCH content repeats transmission.UE can know MCCH all in this community and its corresponding configuration information (such as by the system information block SIB13 (System Information Block) of BCCH channel of broadcast control (Broadcast Control Channel), how many MCCH are had, the relevant parameters such as amendment cycle MP, the repetition period RP of every bar MCCH) in this community.
MCCH and MBSFN Area is relation one to one; UE just can know the control information of the MBSFN Area corresponding with it by reading MCCH message, such as: the configuration information of the multicast subframe resource of this MBSFN Area, in this MBSFN Area all carry out in the MBMS (namely network side has started the MBMS that sends) of (ongoing) and the controling parameters (such as: parameter MBMS-SessionInfo-r9, sessionId-r9, serviceId-r9 etc.) etc. of the MBMS of (ongoing) in carrying out.
The feature of MBMS is that the data volume of business is large, and when terminal receives, the duration is long, average data rate relative constancy.These characteristics determines the scheduling of MBMS, control signal configuration is all semi-static, the i.e. schedule information of MBMS, control signal information is all (" for a long time " described here generally refers to the time span of a few second or a few minutes) that " for a long time " remains unchanged.Multicast control channel MCCH (the Multicast Control Channel) information that such system side sends always is likely that one " for a long time " does not have vicissitudinous information (send is because new user all may be had to access at any time always).Like this for the terminal obtaining MCCH information, if the MCCH information of all going reception one not change at every turn, terminal can be caused like this to take electricity, because MCCH contains much information, and reception and resolving compare power consumption.
MBMS notification message is introduced so propose, (English has company to be called MCCHchange notification to notification message, or MBMS notification Indicator, or MBMS notificationinformation, or MBMS notification, Chinese has company to be called MBMS notification message, MBMS announcement information or MBMS indication information etc., in the description that follows, present patent application adopts Chinese with MBMS notification message, English for MBMS notification information), describe next amendment cycle MP MCCH information that will send by a small amount of information and whether there occurs renewal compared with the MCCH information sent in this amendment cycle MP, UE only needs to monitor a small amount of MBMS notification message information, according to MBMS notification message, terminal goes to determine whether receive MCCH information on the horizon again.
The concrete transmission position of MBMS notification message (MCCH notification) is informed by the SIB13 in BCCH channel of broadcast control; When there is overlapping coverage condition in community, a MCCH notification of unified (common) will be used to indicate many MCCH alterations for MCCH all in community; Concrete:
MCCH notification will indicate specifically which bar or which bar MCCH by its payload (payload) and there occurs change, wherein the payload of MCCH notification is 8bits, uses Downlink Control Information DCI (Downlink Control Information) Format 1C to send in physical downlink control channel PDCCH (Physical Downlink Control CHannel); The instruction of the maximum support of MCCH notification 8 MCCH, which bar MCCH a certain bit wherein in concrete MCCH notification is represented and will be informed by system information block SIB13 in BCCH channel of broadcast control.
MCCH notification carries out repeating to send in the amendment cycle MP of MCCH, transmission times is repeatedly (also can be 1 time), and the main purpose repeating to send MCCHnotification in the amendment cycle MP of MCCH improves reception reliability.Change instruction (MCCHnotification) of MCCH message only triggered by MBMS session start, other MCCH message changes reason (such as: session stop, session updated), can not trigger MCCH notification and send; Namely current MCCH Notification can only reflect that the MBMS of MBMS Session Start and which or several MBSFN Area there occurs Session Start, that is, the following information in following MCCH message changes and can't embody on MCCH Notification:
1) configuration information of MCCH channel changes, as: the MBSFN sub-frame configuration information change of a MBSFN area;
2) the Session update (business renewal) of MBMS and Session Stop (service ending);
3) which MBMS there occurs Session Start specific to.
The transmission of MBMS is triggered by MBMS service session start by MCE (Multi-cell/multicast Coordination Entity, multiple cell/multicast scheduling entity); When MCE triggers a certain MBMS session start process, show that this MBMS is about to be transmitted on eating dishes without rice or wine by evolution base station eNB, namely this MBMS will change ongoing state (sending state) on eating dishes without rice or wine;
When this MBMS service has started to send, be called ongoing MBMS service; A certain MBMS trigger by the session start of MCE after, MCCH information corresponding to this business will change, in MCCH information, mainly carry the controling parameters (such as: session identification session Id, service identification service Id etc.) of this MBMS; The MCCH triggered by session start changes, and will trigger MCCH notification further and send; So just can notify that the UE preparing to receive this MBMS upgrades corresponding MCCH content.As shown in Figure 2, show the above-mentioned MCCH triggered by session start and change, the schematic diagram that MCCHnotification sends will be triggered further.
For MBMS, the data that network side sends can be divided into two large divisions: control information and service data information; When two parts information is transmitted on eating dishes without rice or wine, control information counterlogic channel MCCH, service data information counterlogic channel MTCH (MBMS Traffic CHannel MBMS channel), both are indispensable; Because control information sends on MCCH, corresponding message is MCCH message, and therefore, following control information is directly called MCCH control information or referred to as MCCH information by us; Consider the one-to-one relationship of MCCH and MBSFN Area, after UE only learns MCCH information, just can know the control of the associated control parameters of this MBSFN Area and the MBMS Service relevant to this MBSFN Area, configuration parameter information.
By foregoing description, can find out the acquisition of MCCH information, it is very important for receiving MBMS for terminal (or being referred to as receiving terminal, user equipment (UE)); Consider that MCCH information has high-timeliness (namely revising cycle MP at MCCH just may change) outward again, how UE obtains MCCH, just seems extremely important at place's acquisition on what opportunity MCCH.
Such as, if a certain community only cover by the MBSFN Area time, one is entered to the UE of this community (or be called enter this MBSFN Area), from its interested MBMS of selection, to its interested MBMS of acquisition, this UE experienced by several MCCH and has revised the cycle but the process not reading MCCH information; Consider the ageing of MCCH information, now UE is incomplete for the grasp of this moment MCCH information, and to correctly receive MBMS, UE just needs again to read MCCH information.
Even if from its interested MBMS of selection, to in the time period obtained its interested MBMS, user equipment (UE) is monitoring MCCH notification message (MCCHnotification) always, consider that MCCH notification only reflects the reason that MBMS session start triggers, now, if only according to MCCH notification message, UE cannot grasp the comprehensive MCCH information in this moment, it will inevitably receive MBMS to UE and impact, and thus also needs again to read MCCH information.
Therefore, in LTE system, how user equipment (UE) obtains comprehensive MCCH information in time, can accurately complete MBMS reception according to MCCH information the becoming technical issues that need to address.
Summary of the invention
