Lift an object lesson respectively according to different send modes respectively below.

Which sub-district embodiment one, eNB indicate belong within the scope in MCCH.

MCE (Multi-cell/multicast Coordination Entity, the multicast coordination entity) sends MBMS Session Start Request (request is set up in the MBMS meeting) message to eNB, a new session is set up in request, if wherein this session at be that the relevant positional information of session is additionally carried in specific region then need;

After eNB receives request message, return MBMS Session Start Response message to MCE;

ENB sets up the relevant location information of this MBMS session of carrying in the request message according to session, judge whether cell belongs within this positional information scope under it, and optionally determine whether to send MBMSNotification message in view of the above, there is MBMS new business to arrive with notice UE;

ENB sets up the relevant location information of this MBMS session of carrying in the request message according to session, generates the MCCH message of carrying positional information in view of the above, sends on eating dishes without rice or wine;

ENB sends the data-message of new session, and the UE selectivity receives.

Embodiment one specifically can be referring to shown in Figure 6.

The eNB handling process is as follows:

Request message is set up in the MBMS session that step 1: eNB reception MCE sends.

If this MBMS session does not comprise the MBMS positional information, think this session in whole M BSFN zone effectively, then all cell that belong to this MBSFN zone are all thought normally to send and to receive this MBMS session;

If this MBMS session has comprised the MBMS positional information, then judge according to this MBMS positional information whether the cell of eNB belongs within this zone, can send MBMS notification message for the cell within this zone not.

Step 2: eNB sends the MBMS session and sets up response message.

Step 3: eNB sends MBMS notification message.

Step 4: eNB generates the MCCH message carry the MBMS positional information, and wherein the MBMS positional information can be included in tabulation information lists such as (perhaps) TAI of all cell within the scope, sends MCCH message to UE.

Step 4: eNB sends the data of new MBMS session according to the scheduling result of MCE on eating dishes without rice or wine.

The UE handling process is as follows:

Step 1: to not receiving the UE of MBMS session, receive the MBMS notification message of eNB, know that MCCH will change, the UE that has received the MBMS session does not receive MBMSnotification message.

Step 2: UE receives the MCCH information that eNB sends, knowing has new business to initiate, and reads the MBMS positional information, if this MBMS positional information indicates this sub-district not within effective range, then UE does not receive corresponding M BMS session data, otherwise UE determines to receive the MBMS session data.

Embodiment two, eNB carry detailed positional information in MCCH.

Embodiment two is with the difference of embodiment one positional information of the session that eNB carries is not whether to distinguish with whole cell within this position range in MCCH, but carry detailed position range information, for example in the MBMS effective range or in the outer geographical location information of effective range, MBMS effective range or the outer longitude and latitude range information of effective range etc.

The eNB handling process is as follows:

If this MBMS session has comprised the MBMS positional information, think that then the zone of this MBMS positional information correspondence belongs to the MBSFN zone, can send MBMS notification message for the cell within this zone not.

Step 2: eNB sends the MBMS session and sets up response message.

Step 3: eNB sends MBMS notification message to the cell that belongs to this MBSFN zone.

Because the MBMS positional information is detailed position range information, so the sub-district in this scope comprises that the sub-district partly or entirely all in this scope, all sends MBMS notification message.

Step 3: eNB generates the MCCH message of carrying the MBMS positional information, sends MCCH message to UE.

The UE handling process is as follows:

Step 2: UE receives the MCCH information that eNB sends, knowing has new business to initiate, if further MCCH information comprises the MBMS positional information, read the MBMS positional information, position and MBMS positional information according to self judge that if self be positioned within the positional information scope of session, then UE determines to receive the MBMS session data, otherwise UE does not receive corresponding M BMS session data.

Similar with top situation one, the message format here can have two kinds:

A kind of is to increase optional information at each MBMS-SessionInfo among the PMCH-InfoList in MCCH message MBSFNAreaConfiguration territory, be used to indicate the relevant geographical area information of this business, when corresponding positional information territory does not occur, it is effective in this sub-district to give tacit consent to this session, otherwise when the positional information territory occurs, need judge according to the UE particular location.

Another kind is to keep existing session information constant, in MCCH message, carry independent positional information territory+session identification territory, these bit fields are optional, in case positional information territory+session identification territory occurs, then the corresponding position information of each bar session is listed separately one by one or can the multiplexing identical positional information of a plurality of sessions.

The form of more specific location information can be determined or the agreement regulation by core net, when relating to detailed position range information, can be participated in the assistance of mutual or GPS or UE positioning function by UE.

Which session embodiment three, eNB indicate uncorrelated with this subdistrict position in system message.

MCE sends MBMS Session Start Request message to eNB, and a new session is set up in request, if wherein this session at be the specific region then need additionally to carry the relevant positional information of session;

If cell is positioned at outside this conversation region, then eNB sends the SIB13 system message of the identification information that comprises this session;

ENB sets up content in the request message according to session, generates MCCH message, sends on eating dishes without rice or wine;

ENB sends the data-message of new session, and the UE selectivity receives;

Embodiment three specifically can be referring to shown in Figure 7.

The eNB handling process is as follows:

Do not comprise the MBMS positional information if request message is set up in this MBMS session, then think this session in whole M BSFN zone effectively, then all cell that belong to this MBSFN zone are all thought normally to send and to receive this MBMS session;

If this MBMS session is set up request message and has been comprised positional information, then judge according to this positional information whether its cell belongs within this zone, alternatively, can send MBMS notification message for the cell within this zone not.

Step 2: eNB sends the MBMS session and sets up response message.

If cell does not belong within this business band of position, then eNB need send the SIB13 message of change, the flow process of change is with the operation of existing systems message change (specifically can referring to agreement TS36.331), the content of change is for need increase the session identification that need not receive in this cell in SIB13, wherein the initial delivery time of SIB13 change can be according to three time points among Fig. 7 (other times point also can), basic principle be among new SIB13 of maintenance and the MCCH new session content exist the cycle suitable.

Step 3: eNB sends MBMS notification message.

Step 4: eNB generates new MCCH (specifically can referring to agreement TS36.331) according to existing procedure, sends new MCCH message to UE, the corresponding MBMS session case of notice UE.

Step 5: eNB sends the data of new MBMS session according to the scheduling result of MCE on eating dishes without rice or wine.

The UE handling process is as follows:

New SIB13 is read in UE receiving system message change indication, knows which session can not receive in this cell, and same time point can have three, by eNB or agreement regulation.

Step 2: UE receives the MCCH information that eNB sends, and knowing has new business to initiate, if indicated discourse referent and this subdistrict position of SIB13 is uncorrelated, then UE does not receive corresponding M BMS session data, can receive the MBMS session data otherwise UE is definite.

Which business of indication is uncorrelated with this subdistrict position among embodiment four, the PDCCH.

ENB sets up the relevant location information of this MBMS session of carrying in the request message according to session, judge whether cell belongs within this positional information scope under it, and optionally in view of the above decision whether send MBMSnotification message, there is MBMS new business to arrive with notice UE, if cell does not belong within the session relevant position zone, then need notify UE in new PDCCH mode;

If cell is positioned at outside this conversation region, then eNB sends the PDCCH of ML-RNTI (MBMS Location Radio Network Temporary Identity, MBMS position Radio Network Temporary Identifier) scrambling, and wherein content comprises the beacon information of this session;

ENB sends the data-message of new session, and the UE selectivity receives.

Embodiment four specifically can be referring to shown in Figure 8.

The eNB handling process is as follows:

Do not comprise the MBMS positional information if request message is set up in the MBMS session, then think this session in whole M BSFN zone effectively, then all cell that belong to this MBSFN zone are all thought normally to send and to receive this MBMS session;

Step 2: eNB sends the MBMS session and sets up response message.

Step 3: eNB sends MBMS notification message.

If cell does not belong within this business band of position, then need to send the PDCCH of new ML-RNTI (MBMSLocation RNTI) scrambling, flow process is with existing Notification mechanism (specifically can referring to agreement TS36.331), the content of change is for increasing the identification information of the session that need not receive in this cell in PDCCH, the initial delivery time of wherein new PDCCH can be according to three time points among Fig. 8 (other times point also can), basic principle be among new PDCCH of maintenance and the MCCH new session content exist the cycle suitable;

Step 4: eNB generates new MCCH according to existing procedure, sends new MCCH message to UE, the corresponding MBMS session case of notice UE.

The UE handling process is as follows:

UE receives the PDCCH of ML-RNTI scrambling, reads its content, knows which session can not receive in this cell, and same time point can have three, by eNB or agreement regulation.

Step 2: UE receives the MCCH information that eNB sends, and knowing has new business to initiate, if indicated discourse referent and this subdistrict position of PDCCH is uncorrelated, then UE does not receive corresponding M BMS session data, can receive the MBMS session data otherwise UE is definite.
