And in another embodiment of the present embodiment, the present embodiment additionally provides a kind of equipment, the equipment includes：Above-mentioned Fig. 2
The device of any one of the embodiment being related to and/or can screening device.
The present invention is illustrated with reference to the alternative embodiment of the present invention；
This alternative embodiment provides a kind of method that TMGI conflicts are handled based on said apparatus, below by following three kinds of modes
To be illustrated to this alternative embodiment；
Mode 1
In this approach, the BM-SC being each connected with AS to AS, makes the TMGI feedback of the information of its distribution/release
Obtaining AS can know which or which TMGI has been activated.This alternative embodiment is said with reference to the application scenarios of which
It is bright；
Application scenarios 1：
When some application server is connected to one or more MBMS core nets, i.e.,：One AS is connected to one or more
BM-SC, is connected between each AS and BM-SC by MB2 interfaces, and between each BM-SC without contact (in other words,
Two MBMS core nets are without contact), by the Signalling exchange between AS and multiple BM-SC to avoid conflicting for TMGI；
It should be noted that in this approach, MBMS core nets do not include MME, because MME is typically individually disposed.
Include in the application scenarios, the step of this alternative embodiment method：
Step S302：Each BM-SC is by the allocated TMGI list notifications AS；
Wherein, the list includes one or more allocated TMGI, by this way so when AS is connected to 1 or many
When individual BM-SC, the AS is known that all the allocated TMGI.
Fig. 3 is the schematic diagram that 2 MBMS core nets are connected to according to an application server of alternative embodiment of the present invention, such as
Shown in Fig. 3, an AS is connected to 2 BM-SC, and BM-SC1 is assigned with TMGI list 1, and BM-SC2 is assigned with TMGI
List2, then AS can know the allocated TMGI be TMGI list 1 and TMGI list 2；Based on this, the side of the present embodiment
Method step can be,
Step S304：When AS distributes TMGI to BM-SC requests again, the allocated TMGI list are carried,
And indicate that these TMGI are allocated TMGI；
Step S306：The TMGI list of BM-SC feedback allocations；
Wherein, the list can only include the TMGI list of this sub-distribution, can also include the TMGI list of all distribution, i.e., originally
It is sub-distribution and distributing before.
Release process in this alternative embodiment is also possible that BM-SC after MBMS Session stop, by the TMGI of release
List notifies AS, so that AS knows.
Application scenarios 2：
When some MBMS core net is connected to multiple application servers, BM-SC can directly distribute TMGI, according to existing
MBMS flows can work.
Application scenarios 3：
It is similar with above-mentioned application scenarios 1 when multiple MBMS core nets are connected to multiple application servers, mainly by AS to
BM-SC indicates the TMGI activated, it is pointed out that：Here TMGI conflicts refer to identical wide in identical or part
Broadcast what is occurred in region (service area, cell list), if different broadcast areas, not in the model of this alternative embodiment
Enclose.
In addition, having interface between multiple AS, Signalling exchange (including the TMGI activated) is carried out by the interface, to avoid
TMGI conflicts.
Mode 2
In this approach, there is multiple AS, and/or multiple MBMS core nets, but in some region only one MME, can be with
Pass through interacting between BMSC and MME, it is to avoid conflict.Such as：MME-->TMGI list the allocated BM-SC (should
The TMGI list that the BM-SC that TMGI list have all MBMS core nets is distributed).
But in some region MME：It can not typically be localized in view of MME, then MBMS other network elements
(MBMS-GW/MCE) general that a specific MME is connected solely in certain area, the MME receives MBMS-GW
The session start request message of transmission, if including the TMGI (including identical flow ID), identical activated in message
Broadcast area (including part is identical) and identical QoS, then MME send refuse information response, and refer in the response message
Bright Reason For Denial：TMGI conflicts.Further MME can indicate the TMGI locally activated, refusal in refuse information
Message is sent to BM-SC always, and BM-SC, which is received, redistributes TMGI. after refuse information
In this alternative embodiment, MME processing has three kinds of modes：
1) MME receives MBMS session start request message, then (passes through to all BM-SC in the response message
MBMS-GW the local TMGI activated) is indicated；
2) MME receives MBMS session start request message and detects TMGI conflicts, then sends refuse information, and
In refuse information the local TMGI activated is indicated to all BM-SC (by MBMS-GW)；
3) MME periodically indicates the local TMGI activated to all BM-SC (by MBMS-GW).
It should be noted that MME judges that TMGI conflicts refer to：Identical TMGI (potentially includes flow ID), identical
Broadcast area (or part is identical), identical QoS, different MBMS session start request message；If 1) phase
Same TMGI, entirely different broadcast area (without partly or entirely overlapping), then it is assumed that be not conflict；2) identical TMGI,
Identical broadcast area, different QoS, then MME can initiate MBMS session update flows.
Mode 3
Terminal obtains TMGI by USD (customer service description), and business starts/end time, wireless frequency, service area
Etc. information, if it find that conflicting, between such as identical TMGI (identical frequency, identical services region) has at the beginning of difference, then
Terminal sends configured information to application server AS by application layer：TMGI conflicts, and the TMGI, AS that instruction is clashed
Configured information is sent to all BM-SC：TMGI conflicts, and the TMGI that instruction is clashed.
With reference in above-mentioned three kinds, the method and step of this alternative embodiment includes：
Step S402：Some application server device is distributed to one or more BM-SC requests TMGI；
If application server AS is connected to multiple BM-SC, AS can send request message to one or more BM-SC.
The request is comprised at least：TMGI numbers.Second step：BM-SC distributes TMGI and feeds back application server；
Step S404：BM-SC is the TMGI needed for AS is distributed, if can not distribute, and BM-SC is sent to AS to be refused
Message response, TMGI and optional flow ID. that otherwise BM-SC is distributed to AS transmissions
Wherein, 1) BM-SC can retain a number of TMGI for V2X business, then TMGIs of the BM-SC in reservation
The TMGI of middle selection requirement simultaneously notifies AS；The TMGI retained in advance can be by between OAM or AS and BM-SC
Signalling exchange is determined；
If 2) there is interface between BM-SC, allocated TMGI is notified by interface signaling interaction between BM-SC,
The TMGI that so each BM-SC is sent in AS feedback message is exactly still unappropriated TMGI.
If 3) AS is connected to multiple BM-SC, AS will can have been obtained when asking TMGI to each BM-SC
TMGI be placed in request TMGI message, so as to avoid BM-SC from using the TMGI of the allocated mistake.Such as：Some
AS is connected to BM-SC1 and BMS-SC2 simultaneously, and BM-SC1 is used for being assigned with some TMGI (such as：TMGI1,
TMGI2 AS) and by MB2 interfaces has been fed back to, when AS applies for TMGI to another BM-SC2, has been asked
Ask and the TMGI (TMGI1, TIMG2) distributed is carried in message, then BM-SC2 does not just reallocate TMGI1 and TMGI2
；
4) if BM-SC determines that AS demand can not be met, such as TMGI quantity is unsatisfactory for demand or BM-SC is determined
AS unauthorizeds, then BM-SC sends refuse information response to AS, and indicates Reason For Denial in the message：Such as TMGI quantity
Limited or unauthorized AS.
AS can be by multiple V2X service integrations on a TMGI, and AS signals terminal by application layer：TMGI pairs
The V2X business answered.If terminal finds TMGI conflicts, AS. is indicated by application layer
Step S406：Application server initiates activation MBMS carrying requests；
Wherein, AS sends activation MBMS bearing request messages to BM-SC, and the request message is comprised at least：TMGI,
It can additionally include：Broadcast area, V2X business time starteds etc..
Step S408：Judge whether TMGI conflicts, if it is, return to step S404 redistributes TMGI, otherwise continue to walk

MBMS-GW, MME, MCE, eNB, terminal；
1)MBMS-GW：If MBMS-GW have been received by comprising activated TMGI (including identical flow ID),
Identical broadcasts region (or part is identical) and identical QoS session start session start request message, then MBMS-GW
Refuse information response is sent, and indicates Reason For Denial in the response message：TMGI conflicts.Further MBMS-GW can be with
The local TMGI activated is indicated in refuse information, BM-SC, which is received, redistributes TMGI. after refuse information
2)MME：It can not typically be localized in view of MME, then MBMS other network elements (MBMS-GW/MCE)
General that a specific MME is connected solely in certain area, the MME receives the session start that MBMS-GW is sent
Request message, if including TMGI (including identical flow ID), identical broadcast area (including the portion activated in message
Split-phase is same) and identical QoS, then MME sends refuse information response, and indicates Reason For Denial in the response message：TMGI
Conflict.Further MME can indicate the TMGI locally activated in refuse information, and refuse information is sent to always
BM-SC, BM-SC, which are received, to be redistributed TMGI.MME and can receive MBMS session start request after refuse information
When indicate the TMGI that has activated to BM-SC (by MBM-GW), or periodically send and indicate.
3)MCE：MCE includes centralized and distributed two kinds deployment, no matter which kind of deployment, MCE has identical MBMS
Bearer context, then MCE receives the session start request message that MME is sent, if including what is activated in message

Refuse information is responded, and indicates Reason For Denial in the response message：TMGI conflicts.Further MCE can be in refuse information
The middle local TMGI. refuse informations activated of instruction are sent to BM-SC always, and BM-SC is received and redistributed after refuse information
TMGI.
4)eNB：The session start request message that MCE is sent is received, if including the TMGI (bags activated in message
Include identical flow ID) with identical broadcast area (including part is identical), then eNB send refuse information response, and response
Reason For Denial is indicated in message：TMGI conflicts.Further eNB can indicate the TMGI. locally activated in refuse information
Refuse information is sent to BM-SC always, and BM-SC, which is received, redistributes TMGI. after refuse information
5) terminal：Terminal receives V2X business descriptions, such as ESG or USD, wherein at least bag by application layer signaling from AS
Include：TMGI, V2X the business time started.If terminal receives identical TMGI, but the different business time starteds, then
Terminal judges occur TMGI conflicts, then terminal indicates occur TMGI conflicts to AS, and AS redistributes TMGI by BM-SC.
6)AS：Assuming that AS is connected to multiple BM-SC, AS is according to the newly assigned TMGI of BM-SC (including flow ID)
Determine whether that the MBMS activated is carried (by TMGI, broadcast area and QoS identification), be if the same defined as
TMGI conflicts, and then AS redistributes TMGI. to BM-SC requests
Step S410：Set up MBMS carryings.
Wherein, MBMS carryings include following at least one：MBSFN is carried, SC-PTM carryings.
Step S412：AS sends V2X business by MBMS carryings.
