Abstract
The invention relates to a method and a device for transferring information of a multimedia broadcast multicast service control channel MCCH. The method comprises the following steps of: sending repeated period length RP information of the MCCH through a system broadcasting message, wherein the repeated period length RP information is used for determining the MCCH position according to the repeated period length RP information and receiving an MCCH message according to the MCCH position by user side equipment; and sending information used for indicating MCCH subframe distribution in a next MCCH modification period or a plurality of next MCCH modification periods through the MCCH message. Therefore, in the embodiment of the invention, when MCCH subframe distribution also changes, a networkside only needs to modify the content of the MCCH message and update information of MCCH subframe distribution without modifying the system broadcasting message, therefore, UE (User Equipment) which is irrelevant to MBMS (Multimedia Broadcast Multicast Service) service does not need to read the system broadcasting message again and resource waste is reduced.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to method, the Apparatus and system of wireless communication system transferring information of multimedia broadcast multicast service control channel.
Background technology
MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast-multicast service) is one of important content of 3GPP business development.MBMS refers to that mainly network side simultaneously sends to a plurality of recipients in the network to same multi-medium data, transmits than single user, and MBMS has greatly saved interface-free resources.
In the system LTE of Long Term Evolution, network uses MBSFN (Multimedia Broadcastmulticast service Single Frequency Network, multimedia broadcast-multicast service single frequency network) pattern to transmit MBMS.In transmission course, MCCH (the MBMS ControlChannel that is used for control channel, multimedia broadcast multicast service control channel) and be used for MTCH (the MBMS Traffic Channel of service data transmission, the multimedia broadcast-multicast service channel), all being mapped to MCH (Multicast Channel, multicast channel) transmits.This transmission mode just requires a plurality of residential quarters in certain zone to use identical transmission mode in the identical time, sends identical data.These data-signals carry out the merging of physical layer at receiving terminal, have strengthened reception.
In existing systems, when professional and Unicast business was all transmitted in same residential quarter as MBMS, the mode of employing time-division sent out the data of this two classes business by different subframes.Network side by system broadcast message will be wherein the distribution situation notice UE of " non-Unicast subframe ", all " non-Unicast subframes " in the subframe that UE can determine to receive according to system broadcast message." non-Unicast subframe " can comprise the subframe of various different purposes, for example MBMS transmission, location, Relay (relaying) etc.The concrete distribution of subframe can be as shown in Figure 1, white portion is represented the subframe for transmission Unicast data, oblique line is partly represented the subframe for the non-Unicast data of transmission, and wherein the part subframe that takies in the oblique line subframe of MBMS business is called " MBSFN subframe ".Professional for MBMS, two kinds of channel institutes of MCCH and MTCH data carried by data is all transmitted in the MBSFN subframe.
In the practical application, because UE may begin to receive the MBMS business arbitrarily the time, therefore for assurance UE can in time obtain the MBMS control information, and then obtain the MBMS business, network side periodically sends the MBMS control information by MCCH.In the existing communication system, relate to two kinds of cycles in the MCCH transmission of Information process: MCCH repetition period RP (repetation period) and MCCH revise cycle MP (modification period), specifically as shown in Figure 2, each MCCH modification cycle comprises a plurality of MCCH repetition periods; Each MCCH is in the repetition period, and network sends a MCCH message.Same MCCH revises each MCCH repetition period in the cycle, and the content of MCCH transmission is basic identical.But need fast-changing information for some, the data that each MCCH repetition period transmits also may be different.
When user UE will receive the MBMS data, generally need read BCCH (Broadcast ControlChannel, Broadcast Control Channel) earlier, according to system broadcast message, obtain position and the configuration information of MCCH; Read the MCCH channel again, obtain the relevant configuration information of MTCH; By reading the MTCH channel, obtain the MBMS data.Above-mentioned UE obtains in the process of MBMS data, and UE obtains position and the configuration of MCCH by system broadcast message.Therefore, system broadcast message must comprise some information, helps UE to know the position of MCCH.
At present, can realize that UE obtains the position of MCCH by system broadcast message and the technical scheme of configuration mainly contains three kinds:
Prior art one:
Network side sends the repetition period length of three information: MCCH in system broadcast message, the deviant of MCCH repetition period, the location index of (one or more) subframe in the repetition period at MCCH place.
In this technology, the subframe at MCCH place again according to the index value of the subframe at MCCH place, is found in the position that UE calculates the initial radio frames of MCCH repetition period according to the length of MCCH repetition period and deviant.For example: the length of MCCH repetition period is 128 frames, and deviant is that the subframe index at 0, MCCH place is 6.UE can know accordingly when radio frame number SFN satisfies (SFN mod 128)=0, is the initial radio frames position of MCCH repetition period, that is to say that work as SFN=0, be the initial radio frames of MCCH repetition period at 128,256,384,512,640,768,896 o'clock.The 6th work song frame in these radio frames is exactly the position at MCCH place.
Prior art two:
Network side sends the repetition period length of four information: MCCH in system broadcast message, the deviant of MCCH repetition period, first is used for the location index of the subframe of transmission MCCH message in repetition period, an interior sub-frame number that is used for sending MCCH message of repetition period.
In this technology, UE finds first radio frames of repetition period according to length and the deviant of repetition period, according to " first is used for the location index of the subframe of transmission MCCH message in the repetition period ", finds this subframe then, begins to read MCCH message.Each MBSFN subframe afterwards, UE can read MCCH message wherein, till the sub-frame number that reads equals " quantity of the subframe that MCCH is shared " that system broadcast message informs.
Prior art three:
Network side sends the repetition period length of three information: MCCH in system broadcast message, the deviant of MCCH repetition period, and first is used for the location index of the subframe of transmission MCCH message in the repetition period.
Compare with prior art two, system broadcast message does not comprise " the shared sub-frame number of MCCH in the repetition period " information in this technology.During application, UE is since first radio frames of repetition period, according to " first is used for the location index of the subframe of transmission MCCH message in the repetition period ", find first to be used to transmit the subframe of MCCH, read MCCH, and in follow-up subframe, read continuously, until reading complete MCCH message.In the process that reads MCCH message, be the MBSFN subframe if which subframe UE knows, just only read these MBSFN subframes, seek MCCH message; If UE does not know which subframe is the MBSFN subframe, get all subframes even resume studies, till reading complete MCCH message.
The inventor finds that there are the following problems at least in the prior art in realizing process of the present invention:
In the above-mentioned prior art, need in system broadcast message, increase position or the sub-frame number that field illustrates MCCH place subframe, if the method for salary distribution of subframe changes, as: original first subframe as transmission MCCH message in the repetition period, no longer as the MBSFN subframe, at this moment network must be moved to MCCH message other subframe transmission, and this just needs to revise system broadcast message.On the other hand, if the professional large quantities of beginnings of MBMS or end among prior art one and two, the shared sub-frame number of MCCH will change, and this also needs to revise system broadcast message.Therefore, after system sent amended system broadcast message, with the UE of MBMS independent of service also reading system broadcast again, but for these UE, stressed system broadcast message will cause extra expense.

Understanding for ease of to the embodiment of the invention is described in detail the embodiment of the invention below in conjunction with accompanying drawing.
Embodiment one
Fig. 3 is the transmission MCCH method flow schematic diagram that the embodiment of the invention provides, and as shown in Figure 3, flow process comprises:
31: network side sends the repetition period length RP information of MCCH by system broadcast message; Described repetition period length RP information is used for user side equipment and determines the MCCH position and receive MCCH message according to described MCCH position according to described repetition period length RP information;
32: network side sends by MCCH message and is used to indicate in the next MCCH modification cycle or the information of the MCCH subframe distribution in following a plurality of MCCH modification cycles.
According to above-mentioned flow process as can be seen, because MCCH message is carried and is used to indicate in the next MCCH modification cycle or the information of the MCCH subframe distribution in following a plurality of MCCH modification cycles, therefore, when the MBSFN of system configuration subframe distribution changes, and then the subframe distribution that causes MCCH is when also changing, or because the professional large quantities of beginnings of MBMS or end, when the shared sub-frame number of MCCH changes, therefore network side need not revise system broadcast message, only need to revise the content of MCCH message, upgrade the information of MCCH subframe distribution, thereby make and the UE of MBMS independent of service reading system broadcast again, reduced the waste of resource.
Fig. 4 be the embodiment of the invention provide obtain MCCH method flow schematic diagram, as shown in Figure 4, flow process can comprise:
41: user's lateral root is determined the MCCH position according to the repetition period length RP information of the MCCH in the system broadcast message that receives;
42: user's lateral root receives MCCH message according to described MCCH position, and described MCCH message comprises and is used to indicate in the next MCCH modification cycle or the information of the MCCH subframe distribution in following a plurality of MCCH modification cycles; According to being used to indicate in the next MCCH modification cycle in the described MCCH message or the information of the MCCH subframe distribution in following a plurality of MCCH modification cycles, obtain in the described next MCCH modification cycle or the MCCH information in following a plurality of MCCH modification cycles.
According to above-mentioned flow process, indicate schematic diagram (Fig. 5) with reference to the MCCH subframe distribution that the embodiment of the invention provides, the first UE that receives MBMS can be according to the repetition period length RP information of the MCCH in the system broadcast message, first radio frames from the MCCH repetition period, read subframe wherein one by one, after finding the MCCH subframe, UE obtains the content in the MCCH subframe, thereby know that next MCCH revises the information of cycle or the MCCH subframe distribution of a plurality of MCCH (the following modification cycle is MCCH and revises the cycle) in the modification cycle, thereby can know and know which subframe is the MCCH content all be distributed in in next modification cycle or a plurality of modification cycle, and UE just can directly read the MCCH content like this.Therefore, when the MBSFN of system configuration subframe distribution changes, and then the subframe distribution that causes MCCH is when also changing, or because the professional large quantities of beginnings of MBMS or end, when the shared sub-frame number of MCCH changes, network side need not so revise system broadcast message, only needs to revise the content of MCCH message, upgrades the information of the subframe distribution of MCCH.Like this, UE just can be known the MCCH subframe distribution situation of each MCCH repetition period (the following repetition period is the MCCH repetition period) in next modification cycle or a plurality of modification cycle by MCCH message, thereby directly reads the MCCH content in the modification cycle subsequently.
Need to prove, when UE receives the MBMS business for the first time, owing to lack the information of MCCH subframe distribution, so need begin to detect one by one each subframe from MCCH first subframe in the repetition period, till reading complete MCCH message, (determine the subframe at MCCH place).Certainly, UE also may further dwindle the hunting zone according to the out of Memory in the system broadcast message.For example, if UE after knowing the repetition period length RP information of MCCH, can determine non-Unicast subframe according to the information that comprises in the system broadcast message, then UE can only detect in these non-Unicast subframes and determine the MCCH subframe in the process of search MCCH.Further, if UE can determine the MBSFN subframe according to the information that comprises in the system broadcast message, then UE can only detect in these MBSFN subframes and determine the MCCH subframe in the process of search MCCH.Further, if UE can be according to the information that comprises in the system broadcast message, determine to be assigned with the subframe as transmission of MCH (having shone upon the MCH of MCCH), then UE is in the process of search MCCH, can only in being assigned with as the subframe of transmitting this specific MCH, these detect, to determine the MCCH subframe.In an embodiment, system broadcast message can also comprise the deviant offset information of MCCH repetition period.UE can also further determine the position that the MCCH repetition period begins according to offset information.Offset information may be decided to be 0 or other fixed numbers or equal other parameter approximately; When offset information is decided to be 0 or other fixed numbers or equal other parameter approximately, this offset information also can be not included in the system broadcast message, and the mode by prior setting gets final product.
Because MCCH message begins to send from MCCH first MBSFN subframe in the repetition period usually, so UE can detect the MCCH subframe soon.Though UE needs several milliseconds time to resolve the MCCH message of reading, and before message parse is finished (or before receiving other MBMS business datum), UE receives possible data by all MBSFN subframes, to seek MCCH message.But this flow process only need be carried out once, so can't have much impact to overall power consumption.After UE reads MCCH message for the first time, just can from MCCH message, know the distribution of the MCCH subframe in next modification cycle or a plurality of modification cycle, afterwards, UE just can read the subframe that the MCCH content is arranged that these are known in advance targetedly, read MCCH message with the first time and compare, power consumption significantly reduces.
Embodiment two
In this embodiment, be used to indicate the information of the MCCH subframe distribution in next modification cycle or a plurality of modification cycle, be specially: be used to indicate the bit map that transmits all subframes of MCCH information in the MCCH repetition period.
As shown in Figure 6, corresponding concrete processing procedure can comprise:
61: network side sends the repetition period length RP information of MCCH by system broadcast message; Described repetition period length RP information is used for user side equipment and determines the MCCH position according to described repetition period length RP information, and receives MCCH message according to described MCCH position;
62: network side sends by MCCH message and is used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles, transmits the bit map of all subframes of MCCH information in the MCCH repetition period.
In the above-mentioned flow process, network side sends a bit map by MCCH message, can indicate UE which subframe in the next one is revised cycle or a plurality of modification cycle to have the MCCH content to transmit.For example, each bit represents a subframe, and " 0 " expression does not have the subframe of MCCH content, and " 1 " expression has the subframe of MCCH content.From first subframe of MCCH repetition period section start, bitmap lengths covers all subframes that transmit the MCCH content, if length is not 8 integral multiple, can select with " 0 " polishing, and polishing is not filled with reservation bit.
Concrete as: transmit in three subframes of first radio frames of MCCH content in the repetition period: #2, #3, #6, then bit map is: 00110010.As shown in table 1:
| | # | 0 | #1 | #2 | #3 | #4 | #5 | #6 | #7 |
| |
0 | 0 | 1 | 1 | 0 | 0 | 1 | 0 |
The bit map of table 1:MCCH subframe distribution
According to above-mentioned flow process, the first UE that receives MBMS can be according to the repetition period length RP information of the MCCH in the system broadcast message, first radio frames from the MCCH repetition period, read subframe wherein one by one, after finding MCCH message, UE obtains being used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles in this MCCH message, transmit the bit map of all subframes of MCCH information in the MCCH repetition period, and know which subframe has the MCCH content to transmit in next modification cycle or a plurality of modification cycle.UE just can directly read the MCCH subframe in subsequently modification cycle like this.Therefore, when the MBSFN of system configuration subframe distribution changes, and then the subframe distribution that causes MCCH is when also changing, or because the professional large quantities of beginnings of MBMS or end, when the shared sub-frame number of MCCH changes, network side need not so revise system broadcast message, only needs to revise the content of MCCH message.
Embodiment three
In the present embodiment, network side sends a bit map by MCCH message, is used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles, transmits all subframes of MCCH information in the MCCH repetition period; But because according to existing protocol, first subframe from MCCH repetition period section start, #0, #4, #5, #9, these 4 subframes may be used for the transmission beep-page message, therefore network side passes through in the bit diagram of MCCH message transmission in the present embodiment, from first subframe of MCCH repetition period section start, except subframe # 0, #4, #5, #9, each bit represents a subframe.Same, " 0 " expression does not have the subframe of MCCH content, and " 1 " expression has the subframe of MCCH content.Bit map length covers all subframes that transmit the MCCH content, if length is not 8 integral multiple, then uses " 0 " polishing.
Concrete as: transmit in three subframes of first radio frames of MCCH content in the repetition period: #2, #3, #6, bit map is: 011100.As shown in table 2:
| | # | 1 | #2 | #3 | #6 | #7 | #8 |
| |
0 | 1 | 1 | 1 | 0 | 0 |
The bit map of table 2:MCCH subframe distribution
Other processing procedure of present embodiment is identical with embodiment two principles, no longer repeats here.
Embodiment four
In the present embodiment, network side sends a bit map by MCCH message, is used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles, transmits all subframes of MCCH information in the MCCH repetition period.If can indicate MCH sub-frame allocation pattern MSAP among the BCCH, that is: the set of the subframe of each MCH use, the subframe collection that the MCH of BCCH indication simultaneously shines upon, then in this case, the bit map that sends only need be indicated in the employed subframe of this MCH, and which subframe is used for transmission MCCH content.Same " 0 " expression does not have the subframe of MCCH content, and " 1 " expression has the subframe of MCCH content.Bit map length covers all subframes that transmit the MCCH content, if length is not 8 integral multiple, then can use " 0 " polishing.
Concrete as: the MCCH content is transmitted in three subframes of first radio frames of MCCH in the repetition period: #2, #3, #6, and the shared subframe set of the MCH that BCCH has indicated MCCH to shine upon is #1, #2, #3, #6, the #7 of each radio frames, and then bit map is: 01110.As shown in table 3 below:
| | # | 1 | #2 | #3 | #6 | #7 |
| |
0 | 1 | 1 | 1 | 0 |
The bit map of table 3:MCCH subframe distribution
Other processing procedure of present embodiment is identical with embodiment two principles, no longer repeats here.
Embodiment five
Among this embodiment, network side is by the next modification cycle that is used to indicate of MCCH message transmission or the information of the MCCH subframe distribution in a plurality of modification cycle, be specially, be used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles, first is for the start position information of the position of the subframe that transmits the MCCH content in the MCCH repetition period.
As shown in Figure 7, corresponding concrete processing procedure can comprise:
71: network side sends the repetition period length RP information of MCCH by system broadcast message; Described repetition period length RP information is used for user side equipment and determines the MCCH position according to described repetition period length RP information, and receives MCCH message according to described MCCH position;
72: network side sends by MCCH message and is used to indicate in the next MCCH modification cycle or in following a plurality of MCCH modification cycles, and first is for the start position information of the position of the subframe that transmits the MCCH content in the MCCH repetition period.
In the above-mentioned flow process, start position information can begin counting from first subframe in first radio frames of MCCH repetition period; Or first the non-Unicast subframe in first radio frames of MCCH repetition period begins counting; Or from MCCH in the repetition period, first subframe that MCH (MCH of MCCH mapping) takies begins counting; Or from first MBSFN subframe begin the counting; Or agreement is decided to be first MBSFN subframe approximately; Or agreement is decided to be first MBSFN subframe of corresponding MCH approximately.From the subframe of start position information indication, the subframe of follow-up transmission MCCH content may be continuous, also may be discontinuous.
For example, the original position that transmits the subframe of MCCH content is 2, can represent that the #2 subframe in MCCH first radio frames in the repetition period begins to send the MCCH content.According to this start position information, UE can find the #2 subframe in first radio frames in the MCCH repetition period in the next MCCH modification cycle, begin to read the MCCH content, till reading complete MCCH content.
According to above-mentioned flow process, the first UE that receives MBMS can be according to the repetition period length RP information of the MCCH in the system broadcast message, first radio frames from the MCCH repetition period, read subframe wherein one by one, after finding the MCCH subframe, UE obtains the content in the MCCH subframe, and knows that interior first of MCCH repetition period in next modification cycle or a plurality of modification cycle is used for position of the subframe of transmission MCCH content, and UE just can be easy to read the MCCH content like this.Therefore, when the MBSFN of system configuration subframe distribution changes, and then the subframe distribution that causes MCCH is when also changing, or because the professional large quantities of beginnings of MBMS or end, when the shared sub-frame number of MCCH changes, network side need not so revise system broadcast message, only needs the content of modification MCCH message, and for example first is used for the positional information of the subframe of transmission MCCH content in the renewal indication MCCH repetition period.Like this, UE just can be known the MCCH subframe position of MCCH repetition period in next modification cycle or a plurality of modification cycle by MCCH message, thereby directly reads the MCCH content in the modification cycle subsequently.
Embodiment six
Among this embodiment, network side is by the next modification cycle that is used to indicate of MCCH message transmission or the information of the MCCH subframe distribution in a plurality of modification cycle, be specially, indicate the quantity information of all subframes that are used for transmission MCCH information in the MCCH repetition period.
As shown in Figure 8, corresponding concrete processing procedure can comprise:
81: network side sends MCCH repetition period length RP information by system broadcast message; Described repetition period length RP information is used for user side equipment and determines the MCCH position according to described repetition period length RP information, and receives MCCH message according to described MCCH position;
82: network side sends by MCCH message and is used to indicate in next modification cycle or a plurality of modification cycle, an interior quantity information that is used for all subframes of transmission MCCH information of MCCH repetition period.
According to above-mentioned flow process, after UE is known the quantity information L of all subframes that transmit MCCH information, in the next one modification cycle, first MBSFN subframe in MCCH first radio frames in the repetition period, read MCCH information, read L MBSFN subframe continuously, obtain complete MCCH content.
