Description

Collocation method, equipment and the system of a kind of MBMS dispatching cycle

Technical field

The present invention relates to the communications field, relate in particular to a kind of MBMS collocation method, equipment and the system of dispatching cycle.

Background technology

MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast multi-broadcasting business) organizes 3GPP by global standardsization (The 3 ^RdGeneration Partnership Project, third generation partner program) propose, MBMS refers to that a data source to the point-to-multipoint service that a plurality of users send data, has realized that Internet resources are shared, comprise that mobile core network and access network resource are shared, especially interface-free resources.The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can realize the multimedia service multicast and the broadcasting of two-forty, has complied with the trend of following mobile data development.

At present, the channel of MBMS regulation comprises: MCCH (Multicast Control Channel, multicast control channel), MTCH (Multicast Traffic Channel, the multicast service channel) and MSCH (Multicast Scheduling Channel, the multicast scheduling channel), these three channels all are logic channels, wherein, MCCH is used for transmission network side and UE (User Equipment, user terminal) puts the control information of multiple spot between, be the point-to-multipoint down channel of network side to the control information of UE MBMS transmission, a MCCH controls one or more MTCH.MCCH is at MBSFN (Multicast/BroadcastSingle Frequency Network, be mapped to MCH (MulticastChannel when multicast/multicast single-frequency network network) transmitting, Multicast Channel) on, when carrying out non-MBSFN transmission, be mapped on the DL-SCH (DownlinkShared Channel, DSCH Downlink Shared Channel).

MSCH is used for putting between transmission network side and the UE service dispatching information of multiple spot, and MSCH also can be mapped to MCH or be mapped on the DL-SCH.

MTCH is used for putting between transmission network side and the UE business datum of multiple spot.

More than three channel a kind of MBMS in the prior art transmission method as shown in Figure 1, may further comprise the steps:

Step 101, network side send broadcast, and (System Information Block5 SIB5) to terminal, indicates the configuration information of MCCH;

Step 102, UE monitors corresponding M CCH according to the configuration that receives;

Step 103, UE receives the MCCH signaling of network side transmitted;

This MCCH signaling comprises the configuration information of scheduling configuration information (as: the transmission cycle of schedule information, time started point etc.) and MTCH; The scheduling configuration information can comprise: the information such as duration length of the length of dispatching cycle, scheduling starting point, finishing scheduling point, scheduling.In addition, in some agreement, the scheduling configuration information is called MSAP (MCH subframe allocation pattern) occasion (constantly) configuration information again, correspondingly, the length of dispatching cycle is called MSAP occasion Cycle Length, scheduling starting point and is called the duration length that duration length that MSAP occasion starting point, finishing scheduling point be called MSAP occasion end point, scheduling is called MSAP occasion.The scheduling configuration information is that title is different with MSAP occasion configuration information, and concrete interior perhaps effect is identical, that is to say the scheduling configuration information in the embodiment of the invention, also can be called MSAP occasion (constantly) configuration information.

As shown in Figure 2, send the MCCH channel during MBMS in 3G and LTE R9 discusses modification cycle and repetition period can be set, MCCH information is constant in the modification cycle, and carries out repetition with the repetition period.UE can receive repeatedly identical MCCH information in the modification cycle like this, reads the MCCH loaded information as long as correct reception once just can correctly be separated.

Step 104, UE monitors corresponding M SCH according to the configuration information that receives;

Step 105, UE receives the schedule information of the MBMS on the MSCH;

Step 106 is determined corresponding M TCH according to configuration information and schedule information, receives data.

The message of the last transmission of MCCH comprises the public point to multi-point wireless beared information of MBMS (MBMSCommon p-t-m RB Information), MBMS current area P-T-M wireless loading information (MBMS Current Cell p-t-m RB Information) etc., these information have provided the configuration information of scheduling configuration information relevant with MBMS (as: the transmission cycle of schedule information, time started point etc.) and MTCH etc.Schedule information can perhaps send as the part of MAC head or by MAC CE by for example MSCH transmission of dedicated logical channel.Wherein, if adopt MSCH to send schedule information, MSCH is used to transmit the schedule information of the related MTCH of corresponding MCCH so.UE is according to the professional relevant radio bearer (RadioBearer of the MBMS of its subscription of information configuration on the MCCH, RB), monitor corresponding MBMS schedule information afterwards, determine to wish that according to the MBMS schedule information MTCH that receives begins (and end) time, receive the MBMS business datum.

In order to improve the utilance of resource, can carry out multiplexingly usually to the data of different business, in same subframe, transmit different business, promptly in a subframe, can send the data of different business, as shown in Figure 3.When multiplexing mechanism is used, in a period of time, send data and be good in the mode of business module, that is: send all data of professional 1 earlier, send all data of professional 2 etc. then.By this way, the user can carry out DRX (discontinuous reception in the business that does not have it to wish to receive, be meant discontinuous reception descending scheduling of terminal and downlink data, when not needing downlink data receiving, terminal can be in dormancy (sleep) state, reach purpose of power saving), to reduce electric quantity consumption.

For UE can be received needed MBMS business in the suitable moment, network need send certain schedule information to UE the current MBMS business information that provides of UE network is provided.Schedule information is based on sending dispatching cycle, and schedule information was upgraded in each dispatching cycle, is used to indicate the information of the MBMS business that sends in whole dispatching cycle, comprises professional beginning (and finish time) etc., as shown in Figure 4.

In the prior art, schedule information can perhaps send as the part of MAC head or by MAC CE by for example MSCH transmission of dedicated logical channel.

But, no matter send schedule information in above-mentioned which kind of mode, schedule information all is based on and transmits dispatching cycle, be independent of dispatching cycle such as modification cycle of above-mentioned MCCH or repetition period etc., before business datum transmits, not only need to dispose modification cycle parameter and the repetition period parameter of MCCH, also need the special configuration parameter of dispatching cycle, comprise length, the zero-time of dispatching cycle or the termination time etc. of dispatching cycle.Because the schedule information difference of different dispatching cycles, all need the parameter of dispatching cycle be configured when changing therefore each dispatching cycle.

By adopting method provided by the invention, the incidence relation of the modification cycle of the network equipment and terminal equipment agreement MBMS dispatching cycle and MCCH or the repetition period of MCCH, send the modification cycle of relevant parameter and MCCH or the repetition period of MCCH according to this incidence relation to terminal equipment, make terminal equipment obtain dispatching cycle according to relevant parameter and incidence relation, and the configuration parameter that does not need to send dispatching cycle to terminal equipment, the transmission of saving dispatch.

Introduce the MBMS provided by the invention collocation method of dispatching cycle in detail below in conjunction with a concrete application scenarios, wherein, the modification of MBMS dispatching cycle and MCCH is periodic associated, the length of MBMS dispatching cycle is related with the length in the modification cycle of MCCH, the zero-time of dispatching cycle is related with MCCH modification cycle zero-time, as shown in Figure 6, may further comprise the steps:

Step s601, the length of the network equipment and terminal equipment configuration dispatching cycle and MCCH revise the relation between the length in cycle.

MCCH is used for the control information of putting multiple spot between transmission network side and the UE (User Equipment, user terminal), is the point-to-multipoint down channel of network side to the control information of UE MBMS transmission, and a MCCH controls one or more MTCH.MTCH is used for putting between transmission network side and the UE business datum of multiple spot.

The information of MCCH all may change in each modification cycle, and the change of each MCCH just means the change of MTCH.MSCH is used for putting between transmission network equipment and the terminal equipment service dispatching information of multiple spot, when MTCH changes, the data of transmitting between the network equipment and the terminal equipment change, accordingly, the service dispatching information of putting multiple spot between the network equipment of MSCH transmission and the terminal equipment changes.Therefore, the network equipment and terminal equipment can be the configurations of joining together the dispatching cycle of the modification cycle of MCCH and MBMS.

Should be with in the scene, the network equipment and terminal equipment can adopt the method for joining together to dispose the dispatching cycle of the modification cycle of MCCH and MBMS earlier that configuration MCCH revises the cycle, the mode in configuration schedules cycle again on the MCCH basis in modification cycle.

As shown in Figure 7, the network equipment and terminal equipment can be arranged the length in configuration schedules cycle for revising the 1/N of Cycle Length, and wherein N is an integer, for example 1/4 times;

Perhaps, the network equipment and the length in terminal equipment agreement configuration schedules cycle are K times of modification cycle, and wherein K is an integer;

Perhaps, the relation between the length of the network equipment and terminal equipment dispatching cycle and the length in the cycle of modification adopts following formula to be expressed as:

Modification cycle=2exp (M) * dispatching cycle;

Wherein, M is an integer, and exp () represents power function.

When M greater than 0 the time, dispatching cycle is less than the modification cycle, the length of dispatching cycle is integer/one that revises Cycle Length times; When M less than 0 the time, dispatching cycle, the length of dispatching cycle also can be configured to the integral multiple in the cycle of revising greater than the modification cycle; Equal the modification cycle dispatching cycle when M equals 0.

Step s602, the zero-time of the network equipment and terminal equipment configuration dispatching cycle and MCCH revise the relation between the cycle zero-time.

Concrete, the network equipment is identical with MCCH modification cycle zero-time with the zero-time that terminal equipment can be arranged the configuration schedules cycle, and perhaps the zero-time territory MCCH of dispatching cycle revises the zero-time existence skew in cycle.

For latter event, the side-play amount that the zero-time of dispatching cycle and MCCH revise the zero-time in cycle can be provided with as required flexibly.For example, comprise some repetition periods in the modification cycle, the time of each repetition period is 50ms, and the time of a dispatching cycle also is 50ms, the interior time that sends the MBMS control information of repetition period needs 5ms, and the interior time that sends schedule information of dispatching cycle needs 5ms; If then the zero-time in MCCH modification cycle is identical with the zero-time of MCCH repetition period, when for example all being 0ms, the zero-time of dispatching cycle can postpone to be 5ms.Just in the repetition period of 50ms (also being dispatching cycle), preceding 5ms is the MCCH content, and 6～10ms is the schedule information content, and 11～50ms is the content of MTCH.

Step s603, network side sends broadcast to terminal equipment, carries the configuration information of MCCH in this broadcast.

Step s604, terminal equipment is monitored corresponding M CCH according to the configuration that receives, and receives the MCCH signaling.

The modification cycle, the repetition period that comprise MCCH in this MCCH signaling, and the MBMS dispatching cycle of above-mentioned configuration.

Should can also comprise the relevant parameter that the network equipment sends to terminal equipment in the MCCH signaling with in the scene, this relevant parameter comprises cycle parameter and time span parameter, and wherein, cycle parameter and time span parameter are concrete numerical value.The relation that the zero-time of above-mentioned N, K, M and dispatching cycle and MCCH revise between the cycle zero-time can be determined by this relevant parameter.For example can carry the variables L of this length relation of sign in the MCCH signaling, this L is assignment as required, and for example L is 5 o'clock, and the length that can represent dispatching cycle is 5 times of modification cycle; Can also comprise the zero-time of the dispatching cycle of disposing among the above-mentioned steps s602 and the physical relationship between the MCCH modification cycle zero-time in the MCCH signaling, for example can carry the variable T of this time relationship of sign in the MCCH signaling, T is assignment according to actual needs, for example during T=10, the zero-time of expression dispatching cycle is revised the cycle zero-time than MCCH and is delayed 10ms.

Certainly, carry the physical relationship of length with the length in the cycle of modification of dispatching cycle in the MCCH signaling, perhaps the zero-time of dispatching cycle can also be passed through other modes with the physical relationship of the zero-time in the cycle of modification, this mode is the mode of arranging with terminal equipment, after terminal equipment receives the MCCH signaling, the occurrence that needs be can from the MCCH signaling, get access to, and MBMS length and the zero-time of dispatching cycle obtained according to this occurrence.

Step s605, terminal equipment is determined corresponding M TCH according to configuration information and schedule information, receives data.

Terminal equipment gets access to the physical relationship of length with the length in the cycle of modification of dispatching cycle, and the physical relationship of the length of carrying dispatching cycle in the MCCH signaling and the length in the cycle of modification, length and the time of determining dispatching cycle according to the length of revising the cycle in this MCCH signaling and time then.Further, terminal equipment is according to zero-time and the Cycle Length of dispatching cycle, obtain corresponding scheduling information, determine the MTCH of needs monitoring, and then receive the data of network side transmission from this MTCH according to the schedule information of configuration information in the MCCH signaling and reception.

Should be with in the scene, network side sends the MCCH signaling to terminal equipment, carry the relation between the length in modification cycle of the length of MBMS dispatching cycle and MCCH by the MCCH signaling, and the zero-time of MBMS dispatching cycle and MCCH revise the relation between the cycle zero-time; Network side also can adopt other modes to notify relation between the modification cycle of terminal equipment above-mentioned MCCH dispatching cycle and MCCH, for example set up privately owned message between network side and the terminal equipment, by the relation between the modification cycle of this privately owned message transmission MCCH dispatching cycle and MCCH.

Should be with in the scene, relation between the modification cycle of MCCH dispatching cycle and MCCH can also be sent to terminal equipment by network side by MSCH, this moment, network side did not need to carry the length of dispatching cycle in the message that terminal equipment sends by MSCH, information such as the zero-time of dispatching cycle and finish-time, and only need carry dispatching cycle described in the above-mentioned steps s604 and the physical relationship of revising the cycle, be the length and the multiple value of the length in the cycle of modification or the M value among the step s601 of dispatching cycle, and the concrete time value of the zero-time of dispatching cycle and the skew of the zero-time in the cycle of modification, for example 10ms.

Introduce the MBMS provided by the invention collocation method of dispatching cycle in detail below in conjunction with another concrete application scenarios, wherein, MBMS is related with the repetition period of MCCH dispatching cycle, the length of MBMS dispatching cycle is related with the length of the repetition period of MCCH, the zero-time of dispatching cycle is related with the zero-time of the repetition period of MCCH, as shown in Figure 8, may further comprise the steps:

Step s801, the length of the network equipment and terminal equipment configuration dispatching cycle and the relation between the length of MCCH repetition period.

The MCCH channel can be provided with modification cycle and repetition period, and MCCH information is constant in the modification cycle, and carries out repetition with the repetition period.Like this, terminal equipment can receive repeatedly identical MCCH information in the modification cycle, reads the MCCH loaded information as long as correct reception once just can correctly be separated.When the repetition period of MCCH changes, MCCH information changes, accordingly, the information of MTCH changes, change to the data that terminal equipment sends by the network equipment, and then the service dispatching information that causes putting multiple spot between the network equipment of MSCH transmission and the terminal equipment changes.Therefore, the network equipment and terminal equipment can be the configurations of joining together the dispatching cycle of the repetition period of MCCH and MBMS.

Concrete, the network equipment disposes the MCCH repetition period earlier with terminal equipment, configuration schedules cycle again on the basis of MCCH repetition period.

Should be with in the scene, the length of the network equipment and terminal equipment configuration dispatching cycle is the 1/N of repetition Cycle Length, wherein N is an integer; Perhaps, the length of the network equipment and terminal equipment configuration dispatching cycle be the repetition period K doubly, wherein K is an integer.

Should be with in the scene, length that the network equipment and terminal equipment can also the configuration schedules cycles and the pass between the length of repetition period are:

Repetition period=2exp (M) * dispatching cycle;

Wherein, M is an integer, and exp () represents power function.

When M greater than 0 the time, dispatching cycle is less than the repetition period, the length of dispatching cycle is integer/one that repeats Cycle Length times; When M less than 0 the time, dispatching cycle, the length of dispatching cycle also can be configured to the integral multiple of repetition period greater than the repetition period; Equal the repetition period dispatching cycle when M equals 0.

Step s802, the zero-time of the network equipment and terminal equipment configuration dispatching cycle and the relation between the zero-time of MCCH repetition period.

Concrete, the network equipment is identical with MCCH repetition period zero-time with the zero-time that terminal equipment can be arranged the configuration schedules cycle, and perhaps there are skew in the zero-time of dispatching cycle and the zero-time of MCCH repetition period.

For example, for the previous case, the network equipment is identical with MCCH repetition period zero-time with the zero-time that terminal equipment can be arranged the configuration schedules cycle, and the length of the repetition period of MCCH is 640ms, and the zero-time skew of the repetition period of MCCH can be configured to 0.The zero-time of dispatching cycle is configured to 0 equally, and is the same with the zero-time of MCCH repetition period, and as long as this moment is configuration M=-2, and then zero-time and the length of MBMS dispatching cycle have determined with regard to unique.

Step s803, network side sends broadcast to terminal, carries the configuration information of MCCH in this broadcast.

Step s804, UE monitors corresponding M CCH according to the configuration that receives, and receives the MCCH signaling.

Should can also comprise in the MCCH signaling with in the scene

The physical relationship of the length of the dispatching cycle of disposing among the above-mentioned steps s801 and the length of repetition period, for example can carry the variables L of this length relation of sign in the MCCH signaling, this L is assignment as required, and for example L is 5 o'clock, and the length that can represent dispatching cycle is 5 times of repetition period; Can also comprise the zero-time of the dispatching cycle of disposing among the above-mentioned steps s802 and the physical relationship between the MCCH repetition period zero-time in the MCCH signaling, for example can carry the variable T of this time relationship of sign in the MCCH signaling, T is assignment according to actual needs, for example during T=10, the zero-time of expression dispatching cycle is delayed 10ms than MCCH repetition period zero-time.

Certainly, carry the physical relationship of length and the length of repetition period of dispatching cycle in the MCCH signaling, perhaps the physical relationship of the zero-time of the zero-time of dispatching cycle and repetition period can also pass through other modes, this mode is the mode of arranging with terminal equipment, after terminal equipment receives the MCCH signaling, the occurrence that needs be can from the MCCH signaling, get access to, and MBMS length and the zero-time of dispatching cycle obtained according to this occurrence.

Step s805, UE determines corresponding M TCH according to configuration information and schedule information, receives data.

Should be with in the scene, network side sends the MCCH signaling to terminal equipment, carry the relation between the length of repetition period of the length of MBMS dispatching cycle and MCCH by the MCCH signaling, and the zero-time of MBMS dispatching cycle and the relation between the MCCH repetition period zero-time; Network side also can adopt other modes to notify relation between the repetition period of terminal equipment above-mentioned MCCH dispatching cycle and MCCH, for example set up privately owned message between network side and the terminal equipment, by the relation between the repetition period of this privately owned message transmission MCCH dispatching cycle and MCCH.

Should be with in the scene, relation between the repetition period of MCCH dispatching cycle and MCCH can also be sent to terminal equipment by network side by MSCH, this moment, network side did not need to carry the length of repetition period in the message that terminal equipment sends by MSCH, information such as the zero-time of repetition period and finish-time, and only need carry the physical relationship of dispatching cycle described in the above-mentioned steps s804 and repetition period, be length and the multiple value of the length of repetition period or the M value among the step s801 of dispatching cycle, and the concrete time value of the zero-time of the zero-time of dispatching cycle and repetition period skew, for example 10ms.
