Description
Technical field
The present invention relates to a kind of multimedia broadcast-multicast service (MBMS, Multimedia BroadcastMulticast
Service the notification technique of state change) is sent, more particularly to a kind of multimedia broadcast-multicast service sends the logical of state change
Perception method and device.
Background technology
With the fast development and the popularization of giant-screen multi-functional mobile phone of Internet, a large amount of mobile data multimedia services
Emerge, such as video conference, television broadcasting, video request program, advertisement, online education, interactive game.These mobile multimedias
Business need multiple users can simultaneously receive identical data, compared with general data, with data volume is big, the duration
The features such as length, delay sensitive.
In order to effectively utilize mobile network side resource, third generation partner program (3GPP, 3rdGeneration
Partnership Project) MBMS is proposed, the business is a kind of skill that data are transmitted from a data source to multiple targets
Art, so as to realize the shared of network side resource, improves the utilization rate of network side resource especially air interface resource.3GPP is defined
MBMS can not only realize message class multicast and the broadcast of plain text low rate, and the wide of high-speed multimedia service can also be realized
Broadcast and multicast, there is provided various abundant videos, audio and multimedia service, this has undoubtedly complied with becoming for following mobile data development
Gesture, is that the development of the third generation (3G, 3rd Generation) communication provides better services prospect.
At present, introduced in Long Term Evolution (LTE, Long Term Evolution) system of R9 versions (Release 9)
MBMS technologies, and be optimized in version 10 (R10, Release10).In R9, the control signaling of MBMS with
User data is separately transmitted, and is referred to as chain of command (CP, Control Plane) and user plane (UP, User Plane).Control
Face controls the transmission of user face data by beginning, renewal and the end of control business, realizes the hair of basic MBMS
Send.MBMS fixed size (can be configured at the initial stage by operator, but can not dynamic change) MBMS SFNs (MBSFN,
MBMS Single Frequency Network) send in region.In R10 versions, in order to improve the resource profit of MBMS systems
With rate, facilitate operator to manage, MBMS technologies are strengthened.Mainly there is the following enhancing of some：
1st, introduce MBMS and count (Counting) mechanism.Its cardinal principle is：Multiple cell/multicast cooperation entity (MCE,
Multi-cell/multicast Coordination Entity) pass through M2 interfaces to evolved base station (eNB, evolved
Node B) send some MBMSs Counting request；ENB is in multicast control channel (MCCH, Multicast
Control Channel) on to user equipment (UE, UserEquipment) send the Counting ask；Receive MBMS
The UE in connected state of business feeds back the reception state of the MBMS for itself receiving to eNB；ENB is by feedback result
Report MCE.The main purpose of Counting mechanism is introduced, is the reception state in order to allow operator to count some MBMSs, root
(or activation/deactivation) business, the utilization rate of raising Radio Resource are hung up/recover according to reception state.
2nd, the resource preemption techniques based on service priority are introduced.Its cardinal principle is：When resource is nervous, priority compared with
MBMS high can be with the resource of the relatively low MBMS of preempting priority.When resource is seized by priority business higher
Afterwards, the relatively low business of priority is suspended, and stops continuing to send.
3rd, the information (Deutsche Telecom's demand) of the band of position is introduced.When UE is located in the effective coverage of certain MBMS
When, the business can be received；After UE removes the region, stop receiving the MBMS.
However, the network side framework and MBMS technologies of LTE and former global system for mobile communications (GSM, Global
System of Mobile communication) and UMTS (UMTS, UniversalMobile
Telecommunication System) there is very big difference.In former GSM and UMTS, MBMS is using wide
Broadcast with two kinds of sending methods of multicast, sending zone can with dynamic change, and have good mechanism ensure point-to-point (PTP,
Point to Point) switching and point-to-multipoint (PTM, Point toMlti-Point) between.Therefore, in former MBMS
In technology, when the MBMS sent by PTM modes is interrupted to be sent, the mode that can be easily switched to PTP continues
Send, UE can continuously receive the business.
In the MBMS technologies of LTE, MBMS by way of enhanced broadcast, in the MBSFN regions of fixed size
Interior transmission.The business for sending seizes transmission resource, or effective coverage hair being deactivated, or by high-priority service
When having given birth to change, will all stop to send.Additionally, network side is likely to, because some other reasons, such as allocate resources to temporarily
Other business, such as emergency communication information or unicast service, or advertising message etc. is sent in the middle of business, it is also possible to it is interim
Stop some business for sending, be further continued for sending after waiting resource grant.Then the UE of the business is being received not
Why solution business interrupts, the method that UE service disconnection reasons are not notified in current technology yet.
Therefore, it is necessary to set the mode that a kind of MBMS for sending sends status change notification, user is notified
The reason for MBMS for currently receiving is interrupted, after user knows the concrete reason of service disconnection, can make corresponding
Countermeasure, for example, stop sending for the business of network side long period, user can such as unicast side by other means
Formula continues access service；Stop sending for of short duration business, user continues to the business after can waiting for a period of time.
The MBMS for sending is interrupted without notifying the specific interruption source of user suddenly, and user can be at a loss as to what to do,
So as to cause poor Consumer's Experience, service quality is set drastically to decline.Regrettably, it is current not relate in the prior art
And the related art scheme of MBMS interrupt notification.
The content of the invention
In view of this, state change is sent it is a primary object of the present invention to provide a kind of multimedia broadcast-multicast service

Specific embodiment
Basic thought of the invention is：When the positive MBMS for sending sends state change, network side notifies to connect
The UE of the MBMS is received, UE user is known the reason for MBMS being currently being received transmission state changes, this
Sample, UE user can select specific next step operation according to the reason for different.
It is by the following examples and referring to the drawings, right to make the object, technical solutions and advantages of the present invention become more apparent
The present invention is further described.
In the present invention, network side passes through Access Layer (AS, Access Stratum) mode or Non-Access Stratum (NAS, Non-
Access Stratum) mode notifies that the currently transmitted MBMSs of UE send the announcement information of state change.So-called AS modes,
Refer to the reason for MBMS that will sending sends state change, be carried on multicast control channel (MCCH, Multicast
Control Channel) or BCCH (BCCH, Broadcast Control Channel) on, be sent to and connect
Receive the UE of the MBMS.Specifically the MBMS can be corresponded to by the way of bitmap (bitmap) or index (index)
The reason for sending state change, and only will notify the indicating bit of bitmap or index to corresponding UE.So-called NAS modes,
Refer to network side by Short Message Service (SMS, Short Messaging Service), MMS (Multimedia Message Service) (MMS,
Multimedia Messaging Service) or other Non-Access Stratum technologies, MBMS is sent the announcement information of state change
It is sent to the UE for receiving the MBMS.
The transmission state of MBMS refers to the transmission of business or does not send.Refer to MBMS that UE is being received in the present invention
Business due to the network side caused by send and stop that (normal MBMS is sent, and the lateral UE of network sends
MBMS Session Stop message, stop MBMS transmission situation be not included in.Herein due to network side reason
When stopping transmission refers to that business is not sent, stop sending due to network side).The transmission of MBMS stops
The reason for can be that due to after Counting, discovery is being received or UE numbers interested in the MBMS are less, therefore
Triggering network side hangs up the MBMS so that the MBMS stops sending in whole MBSFN regional extents；Or due to
Current resource is nervous, and the priority of the MBMS that UE is being received is relatively low, is robbed by priority MBMS higher and account for hair
Resource is sent, so as to stop sending in the whole MBSFN regional extents of the business；Or the MBMS received due to UE
Effective coverage there occurs change, the effective coverage of the MBMS after change and former business effective coverage coverage differ
Cause, some UE in former business effective coverage will be unable to continue to the business；Or because network side temporary resource is not enough,
Need to suspend or hang up some MBMSs, recovered to send again when waiting resource sufficient；Or because temporary needs is wide
Broadcasting some emergency communication information, advertisements etc. needs to temporarily cease transmission or hangs up MBMS etc..Certainly, because UE itself is former
Cause, it is also possible to which generation cannot continue to the situation of the MBMS for receiving.Such case, not in discussion of the invention
Within the scope of.After causing MBMS to stop for these reasons, network side will stop the UE of MBMS to reception
The reason for transmission MBMS is stopped.
The MBMS for sending sends status change notification, can give table by the way of bitmap or index
Show.So-called bitmap modes, refer to notify that certain MBMS for sending sends whether state is sent out by the information of 1bit
Change is given birth to.For example, indicating whether the MBMS for sending is deactivated using the information of 1bit.When what is sent
When MBMS is not deactivated, the information bit is set to " 0 "；When being deactivated, the information bit is set to " 1 ".Certainly, also may be used
To use opposite representation.Additionally, when representing that MBMS sends state change using bitmap modes, it is general to use
The information bit of the integral multiple of 8bit represents, such as 8bit, 16bit, 32bit etc., and this needs to notify UE with specific reference to network side
The MBMS that is sending notice that status change notification includes is sent to represent, when notifying item to be less than 8, use
The bitmap of 8bit；When being less than 16 more than 8, using the bitmap of 16bit.Specifically, when the length L of bitmap be more than
The MBMS sends the multiple of the 8 of status change notification number P, and meetsWhereinRepresent less than the maximum integer of P/8.It refers to the MBMS hair for sending that MBMS sends status change notification
The reason for sending state change, MBMS as mentioned above is deactivated, the resource based on priority is seized, MBMS is effective
One notice item of regional change etc., wherein each reason correspondence.Each information bit sends state change with MBMS in bitmap
The corresponding relation between item is notified, wireless heterogeneous networks (RRC, Radio Resource Control) can be passed through by network side
Signal UE, it is also possible to made an appointment by UE and network side.
So-called index modes, refer to notify whether the MBMS that is sending sends state by way of index
There occurs change.For example, when the MBMS for needing network side to notify that UE is being received sends the notice that state changes
When there are 4 kinds, " 00 " can be used using the index of 2bit respectively, " 01 ", " 10 ", " 11 " represent this 4 kinds of information.It is specific every
Implication represented by individual notice item can notify UE by network side by RRC signaling, it is also possible to be arranged in advance with UE by network side.
Similarly, when there is N (N ＞ 1) kinds to need network side to notify that the MBMS for sending of UE sends status change notification, then
These information, wherein log are represented using the index of M bit2N≤M ＜ log2N+1.MBMS sends status change notification
Implication with it is identical in bitmap, repeat no more here.
It is of course also possible to the MBMS that will sending is transmitted directly to UE the reason for sending state change；Or, will
The MBMS that all transmission states change forms a list (list), will send state change reason and is included in list
In, send jointly to UE.
The notice of the MBMS transmission state change for sending can be sent to by MCCH or BCCH and be received
The UE of the business.Specifically, above-mentioned announcement information can be sent using newly-installed message, it is also possible to by original message
It is middle to increase new information unit (IE, Information Element) to send above-mentioned announcement information.UE receives network side hair
After the announcement information for sending, configured information is shown to user, user can determine what current MBMS services were interrupted according to configured information
Reason, so as to select the corresponding operation of next step.
Specifically, the reason for network side sends MBMS transmission state change, can send a period of time, it is also possible to week
Send always to phase property, untill the normal termination time of the business.For example, being sent when the MBMS is carried using MCCH
During the announcement information of state change, one or more modification cycles (MP, Modification Period) can be sent.
Below by the specific embodiment technical scheme that the present invention is furture elucidated.
Embodiment one
In this example, the announcement information that the MBMS that network side directly will send sends state change is sent to
UE.The announcement information, by the message bearing on MCCH or BCCH, can be a new message, or in existing message
Middle increase carries the new IE of the announcement information.
Specifically, the reason for MBMS transmission state change can be defined using a variable for enumeration type.Such as
Increase an IE, entitled MBMS Suspend Cause, its IE type and reference can be following form：ENUMERATED
(MBMS Counting Suspend,
MBMS ARP pre-empt,
MBMS Admission reject,
Temprory Suspend,
Advertisement,
Unspecified,
...)
Above-mentioned IE can be carried in the message that MCCH or BCCH are newly established, it is also possible to be carried on that MCCH or BCCH is existing to disappear
In the newly-increased IE of breath.Network side stops the reason for sending according to MBMS, and corresponding message is sent to UE.
The UE of MBMS is being received, after receiving above-mentioned message, is being stopped sending MBMS not according to network side
Same reason, selects different countermeasures.When being such as TemporarySuspend when the reason for receiving, when UE waits certain
Between, continue to MBMS；When being MBMS ARPpre-empt when the reason for receiving, UE can be switched to unicast, by list
Broadcast and continue to corresponding service etc..
Specifically, the reason for network side sends MBMS transmission state change, can send a period of time, it is also possible to week
Send always to phase property, untill the normal termination time of the business.For example, when the message is carried using MCCH, can be with
Send one or more MP.
The present embodiment informs UE and is currently being received by way of directly transmitting MBMS and stopping the reason for sending
MBMS stop send the reason for.UE can select appropriate strategy according to the reason, and selection continues to or stops connecing
The business is received, and user can be given certain prompt message, it is to avoid the meaningless wait of user, improve Consumer's Experience.
Embodiment two
In this example, the MBMS that network side will sent by the way of bitmap sends the notice of state change
Information is sent to UE.For cheap in description, only discuss that there is Counting hangs up (or deactivation), is based in the present embodiment
State change these three situations are sent caused by the seizing of service priority, MBMS effective coverage.People in the art
Member it should be appreciated that when there is more MBMSs transmission status change notifications, be using longer bitmap indicating bits
Can represent.
Network side is that the bitmap of the MBMS configuration 8bit that is sending indicates its to send status change notification.
And status change notification and bitmap indicating bits are sent determining MBMS by the way of network side and UE are made an appointment
Corresponding relation, for example, using configuration mode realize above-mentioned corresponding relation is configured in each UE.In the bitmap, the
One position rise represent to MBMS Counting after, discovery receiving or number of users interested in the business compared with
Few, network side is deactivated to the business, and the business stops sending.Put refers to by the indicating positions 1.Similar, the
Two positions are risen and are represented because the priority of the MBMS that UE is being received is relatively low, when network side resource is nervous, the business
Send resource to be seized by priority business higher, the business is stopped transmission；Rise and represent what UE was being received in 3rd position
The effective coverage of MBMS there occurs change, and UE is not currently in the effective coverage after MBMS change.Effective district
The reason for domain changes is probably that operator has carried out reconfiguring for MBSFN regions, it is also possible to because business there occurs
Change, its sending zone also there occurs change accordingly.Network side is originally belonging to the MBMS effective coverage, after change not
Belong to and the notice that business effective coverage changes is sent in the range of the business effective coverage.Certainly, notify item with
Corresponding relation between bitmap indicating bits can also configured in advance in each UE, but RRC signaling is passed through by network side
It is sent to UE in advance.
Fig. 1 is that MBMS of the present invention sends corresponding relation between the announcement information of state change and Bitmap indicating bits
Schematic diagram, can be indicated respectively in the form of bitmap as shown in Figure 1 due to the UE that above-mentioned three kinds of originals are thus resulted in
The MBMS for receiving stops sending.As shown in figure 1, N/A represents not applicable in figure, represent and be not used, can
Used with the extension for remaining future.Certainly, 3 significance bits in bitmap may be located at any position in 8bit, and it is sequentially
Can also arbitrarily arrange, if UE in advance with network side arrange by way of or network side send signaling may determine that
Corresponding relation between service announcements and bitmap indicating bits.In addition, occur simultaneously for two or three situation, can
Indicated simultaneously with the position of corresponding bitmap.UE in this case, can only parse priority notice higher
Or first notice item of parsing, specifically how to operate depending on the implementation of itself of UE, due to realizing that parsing is not the present invention
Emphasis, realization be also easy to, the present invention repeats no more its details.
The announcement information that MBMS sends state change can be carried on MCCH or BCCH and be sent to UE.Specifically
, on MCCH by new RRC information, or new IE can be increased in original RRC information send out the MBMS
The announcement information of state change is sent to be sent to UE.The announcement information that the MBMS sends state change can also be carried on
On BCCH, the UE of the MBMS for receiving the state change is sent to by broadcast message.Here, MCCH refers to that UE is received
The corresponding MCCH in MBSFN regions where MBMS.An announcement information can be set to each MBMS, it is also possible to be directed to
All MBMSs for sending on the MCCH, maintain a business to send status change notification list, for notifying
The notice of the transmission state change of all MBMSs of the UE on the MCCH.When multiple MBSFN are overlapped, respectively
The business of its own is sent on its respective MCCH and sends status change notification list.Similar, when BCCH sends, also may be used
So that using sending respectively, single MBMS sends status change notification or the multiple MBMSs of transmission send state change
Notify list.
Specifically, the reason for network side sends MBMS transmission state change, can send a period of time, it is also possible to week
The transmission always of phase property, untill the normal termination time of the business.For example, when the message is carried using MCCH, can be with
Send one or more MP.
The UE of the MBMS is being received, after receiving the announcement information that the MBMS sends state change,
Read the MBMS sent on MCCH or BCCH and send status change notification or MBMS transmission status change notification list
In business send change notification, and parse the transmission status change notification of the MBMS for itself receiving, parse institute
State notice Xiang Bingxiang UE users to show, inform the reason for UE user's MBMS is interrupted.Specifically, user may be appreciated letter
Breath, refers to such as " MBMS is deactivated ", " MBMS is preempted, and sends inadequate resource ", " MBMS effective coverage change
The similar user such as change " may be appreciated text information.
As network side has deactivated the MBMS that certain UE is being received, then network side is sent by MCCH or BCCH to UE
Business transmission state notification information 1,0,0 ... }.After UE receives the announcement information, the front three of the bitmap information is understood,
It was found that the bit for corresponding to " MBMS is deactivated " is set to 1, then know that the MBMS for receiving is deactivated.Cause
This, UE notify user " distinguished user ... due to, business that you are receiving stops sending.If you are ready
Accessed with unicast, please by confirmation；If stop receive, please by cancel " etc. similar information.Certainly, when implementing, can be with root
Realized according to UE itself, prompt the user with corresponding information.User points out according to UE, chooses whether to continue to business or other behaviour
Make.
The groundless of the business received compared to user terminates, and the present invention is notified of customer service and terminates reason, and
The operation instruction of the business of continuing to is provided a user with, user can be selected to stop being received by MBSFN modes according to instruction
The business, is diverted through the modes such as unicast and continues to the MBMS.It is of course also possible to receive MBMS in UE send
After state notification information, according to UE preset strategies, directly by other means, such as unicast continues to the business, keeps using
The continuity that family MBMS is received.
The present embodiment is mainly by the form of bitmap, and the transmission state of the MBMS that network side is being sent becomes
Change announcement information and UE is sent to by RRC signaling or the new IE of increase, state change is then sent by UE prompting customer services
Concrete reason, and point out user to continue to business by unicast.
Embodiment three
In this example, the MBMS that network side will sent by the way of index sends the notice of state change
Information is sent to UE.For cheap in description, only assume that a total of 4 kinds of network side causes what is sent in the present embodiment
MBMS sends the behavior of state change.Network side is needed by MCCH or BCCH, indicates these to cause in the way of index
The reason for MBMS sends state change, and send it to UE.It will be appreciated by those skilled in the art that more when existing
During interruption source, can be represented using longer index indicating bits.
Network side be UE receiving MBMS configuration 2bit index come indicate its send state change notice
, i.e., using { 00 }, { 01 }, { 11 }, { 10 } four indexes send state change come the MBMS for indicating UE receiving
Reason.Can also may be used by the way of make an appointment index indicating bits and MBMS transmission state change reason corresponding relation
Using when network side is sent the reason for MBMS sends state change to UE for the first time, index indicating bits are sent to UE
Send the information that state change reason notifies the corresponding relation between item with the MBMS, or can also periodically to
UE broadcasts the information of these corresponding relations.It is for instance possible to use following manner：{ 00 } represent due to the MBMS industry that UE is being received
The priority of business is relatively low, and when network side resource is nervous, the transmission resource of the business is seized by priority business higher, the industry
Business is stopped transmission；{ 11 } represent that the effective coverage of the MBMS that UE is being received there occurs change, and UE is not currently in this
In effective coverage after MBMS change；{ 10 } represent that network side needs to send advertising message to UE temporarily or other notify letter
Breath；{ 01 } represent due to send other emergency informations or urgent news in the resource of the MBMS being currently transmitted
Deng, the MBMS that will be currently transmitted stop sending or certain interval of time after send again.Effective coverage changes
The reason for be probably that operator has carried out reconfiguring for MBSFN regions, it is also possible to because business there occurs change, its transmission
Region also there occurs change accordingly.Network side is originally belonging to the MBMS effective coverage, and the business is not belonging to after change

Business sends status change notification { 10 }.After UE receives the notice, the information is understood, found corresponding to temporarily " network side is inserted
Advertisement sends notice, and the MBMS short time stops ", then notify the classes such as user's " just a moment,please, and highlight will continue "
Like information；When network side needs the resource for taking the MBMS being currently transmitted to send urgent news or other similar letters
Breath, current business is stopped to send or resend after a while, then send { 01 } to UE by MCCH or BCCH, and UE is received
To after the notice, corresponding information is shown to user, point out user to reattempt to after a period of time and receive the business；When due to
Internet resource is nervous, when the MBMS for sending is seized by other high-priority services, { 00 } is sent to UE, and UE is to user
Prompting network side resource is nervous, and the MBMS is stopped, and is please accessed by unicast or other modes.It is, of course, also possible to UE
Other corresponding informations are sent, time, the corresponding unicast of the MBMS that such as the time of commercial breaks, MBMS resend
Information of business etc..UE user according to the prompt message, wait for a period of time and continue to business by selection, or turn to unicast after

Send one or more MP.
The groundless of the business received compared to user terminates, and the above method is notified of customer service and terminates reason,
Allow that user selects different operations according to concrete reason.It is of course also possible to receiving the business in UE sends state
After announcement information, according to user or UE preset strategies, such as " business stops for a long time, then switch unicast and continue access ", " business is short
Pause stops, then wait and continuing to a little while ", " stop receive the business " etc., maintain the continuity of customer service reception, carry
Consumer's Experience is shown.
The form that the present embodiment passes through index, the transmission status change notification of the MBMS that will sending passes through RRC
Signaling or new IE are sent to UE, and then UE promptings customer service sends state change reason so that user can be according to UE
The corresponding next step operation of prompting selection.
