Embodiment
In the LTE scheme, the transmission mode of MBMS business is divided into two kinds: a kind of is many cell transmission pattern, and another kind is single cell transmission pattern.In the LTE system, when no matter adopting many cell transmission pattern still to adopt single cell transmission pattern, all be mode MBMS transmission business with PTM.In the LTE system, no longer adopt the mode MBMS transmission business of PTP.
When adopting PTM mode MBMS transmission professional, there is feedback and do not feed back two kinds of mechanism.When adopting many cell patterns MBMS transmission professional, use not feedback mechanism.When adopting single cell pattern MBMS transmission professional, need determine to use feedback mechanism also to be to use not feedback mechanism according to the quantity of the UE that receives the MBMS business.
Wherein, the UE that receives the MBMS business under single cell pattern has independently uplink feedback channel, can feed back and mix automatic repeat requests (Hybrid Automatic Repeat Request, HARQ) affirmation/non-affirmation (ACK/NAK) and channel quality indication (Channel Quality Indicator, CQI) information, HARQ retransmits and Adaptive Modulation and Coding (Adaptive Modulation andCoding, AMC) transmission to carry out.
When adopting single cell pattern MBMS transmission professional, need by counting process or periodicity
The restatement process of the counting quantity that determine to receive the UE of this MBMS business whether reached certain threshold value.Wherein, count process, need the UE that receives the MBMS business to set up the RRC connection for realizing counting process or restatement.
In the LTE scheme, when UE switches from a sub-district in receiving the process of certain MBMS business or during gravity treatment to new sub-district, should consider follow-up processing procedures at the following 4 kinds situations that may occur:
1, new sub-district is adopting the mechanism of not feeding back to transmit this MBMS business, and in this case, new sub-district may adopt single cell transmission pattern also may adopt many cell transmission pattern;
2, new sub-district is adopting feedback mechanism to transmit this MBMS business, and UE can support new sub-district modulating-coding mechanism (Modulation and Coding Scheme, MCS), in this case, single cell transmission pattern is adopted in new sub-district;
3, new sub-district is adopting feedback mechanism to transmit this MBMS business, but UE does not support the MCS mechanism of new sub-district, and in this case, single cell transmission pattern is adopted in new sub-district;
4, this MBMS business is supported in new sub-district, but does not transmit this MBMS business, and in this case, new sub-district may adopt single cell transmission pattern also may adopt many cell transmission pattern.
At above-mentioned 4 kinds of situations that may occur, provided corresponding subsequent processes in the following embodiments respectively.
When UE switches from a sub-district in receiving the process of certain MBMS business or during gravity treatment to new sub-district, if new sub-district is adopting the mechanism of not feeding back to transmit this MBMS business, then this UE can continue to receive this MBMS business in new sub-district.
When UE switches from a sub-district in receiving the process of certain MBMS business or during gravity treatment to new sub-district, if new sub-district is adopting feedback mechanism to transmit this MBMS business, and UE can support the MCS of new sub-district, and then this UE can continue to receive this MBMS business in new sub-district.
When UE switches from a sub-district in receiving the process of certain MBMS business or during gravity treatment to new sub-district, if new sub-district is adopting feedback mechanism to transmit this MBMS business, but UE does not support the MCS of new sub-district, and two kinds of follow-up processing procedures then can be arranged:
The step of first kind of processing procedure comprises:
This UE waits for restatement arrival one number time of this MBMS business;
When restatement arrived one number time, UE initiated RRC and connects the request of foundation, the MCS of the new sub-district of request network side adjustment.
Behind the MCS of the new sub-district of network side adjustment, this UE could correctly receive this MBMS business.But the cycle of restatement number is long usually, and for example the cycle of restatement number is at least 160 milliseconds in 3GPP R6 scheme.When restatement one number time was long, it was also long to cause this UE to interrupt the professional time that receives of MBMS, also just can't guarantee the continuity of the professional reception of MBMS.
The step of second kind of processing procedure comprises:
This UE directly initiates to insert at random request, inserts new sub-district;
This UE sets up RRC and connects in new sub-district, the informing network side is initiated described MBMS business;
This UE is with its MCS informing network side that can support, and the MCS that makes the network side decision whether adjust new sub-district adapts to this UE.
Compare with first kind of processing procedure, second kind of processing procedure can shorten the stand-by period of UE effectively, thereby can guarantee the professional continuity that receives of MBMS better.
When UE switches from a sub-district in receiving the process of some MBMS business or during gravity treatment to new sub-district, if supporting that this MBMS is professional, new sub-district do not transmit this MBMS business, then by following step process:
This UE directly initiates to insert at random request, inserts new sub-district;
This UE sets up RRC and connects in new sub-district, the informing network side is initiated described MBMS business;
This UE is with its MCS informing network side that can support, and the MCS that makes the network side decision whether adjust new sub-district adapts to this UE.
For making those skilled in the art understand the present invention better, below Fig. 1 the method that the embodiment of the invention provides is made more specific description.
In step 101, in the process that receives the MBMS business, UE carries out the sub-district to be shifted.
In step 102, judge that can this UE directly receive this MBMS business in new sub-district.
Wherein, by BCCH and the MCCH that receives new sub-district, can obtain the system message of new sub-district and the relevant signaling of this MBMS business, thereby can obtain the relevant information of this MBMS business.The relevant information of MBMS business comprises: which MBMS business the sub-district supports, MCS that the MBMS business which MBMS business is being transmitted and transmitted is adopted or the like.
Can learn according to the relevant information of MBMS business whether new sub-district supports this MBMS business, whether this MBMS business is transmitted, transmit the MCS that this MBMS business is adopted, by the MCS MCS whether satisfied this MBMS business of transmission is adopted that can learn that relatively UE can support, thereby can learn finally that can UE directly receive described MBMS business in new sub-district.
Explanation by preamble as can be seen, UE carries out the sub-district when shifting, the situation that may occur has 4 kinds.When the 1st kind of situation or the 2nd kind of situation occurring, UE can directly receive this MBMS business in new sub-district; When the 3rd kind of situation or the 4th kind of situation occurring, UE can not directly receive this MBMS business in new sub-district.
If this UE can directly receive this MBMS business in new sub-district, then in step 103, directly receive this MBMS business in new sub-district.
Here need to prove also that under the 1st kind of situation, this UE directly receives this MBMS business and gets final product in new sub-district; And under the 2nd kind of situation, this UE also should insert new sub-district and set up the RRC connection except that directly receiving this MBMS business in new sub-district.Like this, can the informing network side there be new UE to add new sub-district and receives this MBMS business, thereby make network side can correspondingly carry out subsequent treatment.
Under the 2nd kind of situation, UE needs also to judge except that directly receiving this MBMS business in new sub-district whether all receive all shared identical ACK/NAK channel of UE of this MBMS business in new sub-district.If then this UE also sends the ACK/NAK signal of this MBMS business on this ACK/NAK channel.
If this UE can not directly receive this MBMS business in new sub-district, then in step 104, determine whether new sub-district supports this MBMS business.
If this MBMS business is supported in new sub-district, then in step 105, insert new sub-district and set up the RRC connection.
Wherein, when setting up the RRC connection, the MCS informing network side that this UE can should be supported, if this MBMS business is being transmitted in this stylish sub-district, then network side can be adjusted accordingly according to the MCS that this UE can support, so that this UE can receive this MBMS business, for example, from original 16QAM, 1/2 code check changes QPSK into MCS, 2/3 code check; If this stylish sub-district is not transmitted this MBMS business as yet, then network side is when initiating this MBMS business, and the MCS that should adopt this UE to support transmits this MBMS business.
Insert new sub-district and set up process that RRC connects as shown in Figure 2.UE sends and inserts request message at random, and request inserts new sub-district.Network side returns accidental access response message, and so far UE inserts new sub-district.After inserting new sub-district, UE sends RRC and sets up request message, and request is set up RRC and connected, and sets up the ID of the MBMS business that the ID that comprises UE in the request message and UE need receive at RRC.Network side returns RRC and sets up response message, and RRC connection is so far set up and finished.
Wherein, when setting up RRC and connect, can set up the MCS informing network side that request message can be supported UE, also the MCS informing network side that can described UE can be supported by specific signaling by RRC.
After the RRC connection is set up in new sub-district, in step 106, receive this MBMS business in new sub-district.
If this MBMS business is not supported in new sub-district, then in step 107, abandon receiving this MBMS business.
As can be seen, the foregoing description provided a kind of concrete be used for the LTE scheme guarantee the sub-district switch or cell reselection process in can receive the solution of MBMS business constantly.The method that those skilled in the art adopt the foregoing description to describe can be implemented in the MBMS of the reception constantly business in sub-district switching or the cell reselection process at an easy rate.This method realizes simple, and easy operating is also very little to the change of existing system, can accomplish substantially compatible mutually with existing systems, thereby reduced system cost effectively.
