Description
Technical field
The present invention relates to technical field, relate in particular to transmission method, system and the device of a kind of multimedia broadcast-multicast service (MBMS, Multimedia Broadcast Multicast Service) notice (Notification).
Background technology
The be otherwise known as MBMS (eMBMS, evolved MBMS) of evolution of MBMS in Long Term Evolution (LTE, the Long Term Evolution) system, major function is to realize broadcasting and multicast service in the LTE system.At present, the MBMS of version 9 (R9) mainly realizes that by mixed cell namely unicast service is also transmitted in the residential quarter of MBMS transmission business.
The logic channel that eMBMS is relevant comprises:
(1) Broadcast Control Channel (BCCH, Broadcast Control Channel) is used for network to terminal (UE) broadcast system information, and namely system information is transmitted by BCCH.
(2) multicast control channel (MCCH, Multicast Control Channel), be that a point is to the down channel of multiple spot (point-to-multipoint), be used for network to the relevant control information of subscriber equipment (UE) MBMS transmission, this channel has only the UE that can receive the MBMS business just can use.
(3) multicast service channel (MTCH, Multicast Traffic Channel), be a point to the down channel of multiple spot, be used for network to the UE transferring MBMS service data, this channel has only the UE that can receive the MBMS business just can use.
A MCCH can be corresponding to one or more MTCH.The information of MTCH is to be indicated by its corresponding MCCH.
Network utilisation BCCH indicates MCCH to UE, and recycling MCCH indicates MTCH to UE, thereby makes UE correctly be received in the MBMS business that MTCH goes up carrying.
In the MCCH transmission means of in the 3G system, stipulating, the MCCH loaded information is to transmit in the mode of the repetition period of the modification cycle of MCCH and MCCH, in order to guarantee the reliable reception of MCCH, the MCCH loaded information retransmitted with the repetition period of MCCH in the modification cycle of MCCH, UE can receive a plurality of identical information in the modification cycle of MCCH, as long as the correct solution that just receives is once correctly read the MCCH loaded information.
Current LTE agreement has been stipulated the paging form (paging pattern) of Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD), and following table 1 is depicted as the paging form of FDD, and table 2 is depicted as the paging form of TDD:
| Paging density (Ns) | The beep-pager meeting | The beep-pager meeting | The beep-pager meeting | The beep-pager meeting |
| 1 | 9 | Do not have | Do not have | Do not have |
| 2 | 4 | 9 | Do not have | Do not have |
| 4 | 0 | 4 | 5 | 9 |
Table 1
| Paging density (Ns) | The beep-pager meeting | The beep-pager meeting | The beep-pager meeting | The beep-pager meeting |
| 1 | 0 | Do not have | Do not have | Do not have |
| 2 | 0 | 5 | Do not have | Do not have |
| 4 | 0 | 1 | 5 | 6 |
Table 2
Wherein, beep-pager meeting (PO, Paging occasion) is exactly the subframe that subscriber paging may occur, and therefore also can be called the paging subframe.By two top tables as can be seen, for the FDD system, all users' paging only may occur in subframe #0, #4, #5 and #9, and namely subframe #0, #4, #5 and #9 are the paging subframes.And for the TDD system, all users' paging only may occur in subframe #0, #1, #5 and #6, and namely subframe #0, #1, #5 and #6 are the paging subframes.
Paging density (Ns) refers to the number of a paging subframe in the paging radio frames.When Ns=4, in each radio frames in paging cycle 4 paging subframes are arranged all, for FDD, these four subframes are #0, #4, #5 and #9, for TDD, these four subframes are #0, #1, #5 and #6.
In LTE R9, introduced MBMS notice (MBMS Notification) mechanism, specifically comprised:
As shown in Figure 1, when the session as MBMS begins (Session Start), network can send MBMS notice (Notification) to UE, namely there is new MBMS session to begin by Notification subframe (being used for sending the subframe of MBMSNotification) notice UE, UE reads MCCH in the modification cycle of the next MCCH that receives MBMSNotification, from the MBSFN subframe, obtain the specifying information of session (Session), if UE is interested in this MBMS business, then according to the content of MCCH, read corresponding MTCH, receive this MBMS business.
Definition MBMS Radio Network Temporary Identifier (M-RNTI) in the Physical Downlink Control Channel (PDCCH) of physical layer, as MBMS Notification, that is to say, if there is session to begin (SessionStart), then the PDCCH of network in can the Notification subframe in Fig. 1 arranges M-RNTI, and being used for notice UE has new MBMS service conversation to begin.For the current UE that does not receive the MBMS business, receive after the MBMS Notification, will read MCCH in the next one modification cycle, if this UE does not receive MBMS Notification, then it can continue to monitor the Notification subframe, and can not read MCCH.For the UE that receives the MBMS business, need to read MCCH information in each MCCH cycle of revising, do not need to monitor the Notification subframe.
Yet, how sending MBMS Notification by the PDCCH resource for network at present, how UE receives MBMS Notification by the PDCCH resource, does not provide concrete solution.

Embodiment
The embodiment of the invention provides transmission method, system and the device of a kind of MBMS Notification, in order to realizing sending by the PDCCH resource technical scheme of MBMS Notification, and avoids too much the taking of PDCCH resource guaranteed systematic function.
Can comprise scheduling system information (SI-RNTI), paging scheduling (P-RNTI) and the professional schedule information of clean culture (unicast) among the PDCCH, and also need to take the PDCCH resource as the M-RNTI of MBMS Notification.
A kind of schematic diagram that pass through in a MCCH modification cycle all paging subframe transmission MBMS Notification of Fig. 2 for providing in the embodiment of the invention, suppose that a MCCH modification cycle in the MBSFN zone is 10.24 seconds (s), the MCCH repetition period is 2.56s, the default paging cycle of certain residential quarter (default paging cycle) also is 2.56s, and the base station of this residential quarter will be by system broadcasts with the UE in modification cycle, repetition period and the default paging cycle notifying cell of MCCH.
For the residential quarter of FDD system, the paging subframe is subframe #0, #4, #5 and #9.If there is new MBMS service conversation to begin, then as shown in Figure 2, the base station of this residential quarter can send MBMS Notification in all the paging subframes in the next MCCH modification cycle, specifically, be exactly that the base station of this residential quarter is with the subframe #0 of all radio frames in the paging cycle of each 2.56s in the MCCH modification cycle that defines the next 10.24s that new MBMS service conversation begins, #4, send MBMS Notification, total transmission times N=4 * 10.24/2.56 * 2.56/0.01=4096 among #5 and the #9.Wherein, this MBMS Notification is present among the PDCCH of these subframes with the form of M-RNTI.Then, the base station will send new MCCH in the next MCCH modification cycle after sending MBMS Notification.
But if in the MCCH modification cycle that sends MBMS Notification, change has also taken place in system information, and then network can all the paging subframes (PO) in this MCCH modification cycle send beep-page message, and being used for notice UE has system information to change.Therefore, the PDCCH of the paging subframe in this MCCH modification cycle will be taken by M-RNTI, P-RNTI simultaneously.In addition, in these paging subframes, also might comprise the schedule information of SI-RNTI and unicast business.So, adopt this scheme, can cause the load of PDCCH excessive, when M-RNTI had taken too much PDCCH resource, can be used for scheduling system information, paging scheduling and the professional scheduled resources of unicast among the PDCCH will be less, and systematic function is descended.
That is to say, if utilize all paging subframe MBMS transmission Notification, when all the paging subframes in allowing each radio frames are used for MBMS transmission Notification so, can cause the PDCCH load excessive, can influence other purposes of PDCCH, as scheduling system information, paging scheduling, unicast service scheduling etc., cause the entire system performance to descend.
