Background technology
Multimedia broadcast-multicast service (MBMS, Multimedia Broadcast Multicast Service) is one of important content of third generation partner program (3GPP) business development.In MBMS, network side can be simultaneously sends to a plurality of portable terminals in the network with same multi-medium data with the mode of broadcasting or multicast, and than single user's transmission means, MBMS has greatly saved the interface-free resources of system.Formulating in the MBMS R9 release protocol of the Long Term Evolution of accomplishing (LTE) recently; The MBMS business will be through multimedia broadcast-multicast service SFN (MBSFN; Multimedia Broadcast multicastservice Single Frequency Network) transmission, this transmission means is a kind of transmission means of carrying out synchronous transmission at one time with same frequency in a plurality of sub-districts, uses this transmission means can practice thrift frequency resource effectively; Improve the availability of frequency spectrum, and improve coverage rate.
In the prior art; Many sub-districts/multicast coordination entity (MCE; Multi-cell/multicastCoordination Entity) is a kind of logic entity; Can dispose a plurality of MBSFN zones (MBSFN Area) that are used to carry out the MBSFN transmission, and can be regional all evolved base station (eNB, the evolved Node B) distributing radio resource of MBSFN to carry out the MBSFN transmission.Wherein, can comprise a plurality of eNB among a MBSFN Area.The content that all eNB broadcasted in the same MBSFN Area all is identical, and is synchronous.At synchronization, have a plurality of business (service) and in same MBSFN Area, broadcast.The business of broadcasting maybe identical also possibility difference in the different MBSFN Area.For the sub-district, each sub-district can only belong to some MBSFN Area, also can belong to a plurality of MBSFN Area simultaneously.
When subscriber equipment (UE) when being moved, professional if UE is receiving certain MBMS, in order to improve user's impression, need to select the professional sub-district (cell) of this MBMS of broadcasting to supply UE to insert, so that the MBMS that UE can be continued to receive receiving is professional as far as possible.Even further; Interested (not beginning to receive should business if UE is to certain MBMS business; The reason that does not begin to receive possibly be that current area does not provide this business, and perhaps current area provides this business, but user's decision just begins to receive after a while); Then can select to broadcast the UE of the professional sub-district of the interested MBMS of this UE in supplying to move as far as possible and insert, professional so that UE can receive its interested MBMS in new sub-district.
In the prior art, in whole M BSFN Area, all sub-districts are all at the state that carries out the MBSFN transmission or keep carrying out the MBSFN transmission.At this moment; Network side (for example; MCE) will all send identical MBMS business information to all sub-districts among the same MBSFN Area, and the MBSFN transmission is also all being carried out in each sub-district among the MBSFN Area, promptly each sub-district all will receive all MBMS business information that network side sends; Even the above-mentioned MBMS that is broadcasted of UE reception is not professional in certain sub-district, this sub-district also can be broadcasted received MBMS business information in this sub-district.Therefore, there is waste in the MBSFN transmission means of the prior art, taken too much system's available resources, and increased the signaling consumption and the signaling transmission of system greatly system's available resources.
In addition, in order to let the network side can be better for UE provides above-mentioned business continuance, network side at first need be known the professional and interested MBMS of MBMS that UE receiving professional (can abbreviate the business and the interested business that are receiving respectively as, down with).In the prior art; UE can it receiving through MBMS status report (MBMS Counting Response) information reporting professional and/or interested business, comprise the service identification (can be referred to as the MBMS traffic ID) of the professional and/or interested business that this UE is receiving in this MBMS status report messages.But; Do not distinguish business and the interested business of UE that UE is receiving in the above-mentioned MBMS status report messages; Promptly if satisfy receiving with these two conditions interested in any one; UE just should business service identification report to network side, be the business that this UE is receiving but do not indicate which business, which business is the interested business of this UE.Network side is when providing switching target small area or cell reselection priority for UE; Can't pay the utmost attention to the sub-district that the business that is receiving is provided for this UE as switching target small area; Can not promote the priority of frequency that the sub-district place of the business that is receiving is provided for this UE yet, thereby be unfavorable for that network side provides better business continuance for this UE.
Can know that to sum up MBSFN transmission means of the prior art will take a large amount of system's available resources, and increase the signaling consumption and the signaling transmission of system greatly.On the other hand, network side also can't provide better business continuance for UE under the prerequisite of saving system resource.

Embodiment
For making the object of the invention, technical scheme and advantage express clearlyer, the present invention is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
The invention provides a kind of MBMS business transmitting method and system.In said MBMS business transmitting method, in a MBSFN Area, at least one hierarchical region is set, the initial condition of each hierarchical region is state of activation or unactivated state; Be in each sub-district of the hierarchical region of unactivated state, according to the MBSFN transmission that activates message activation self.Through using above-mentioned MBMS business transmitting method and system, can save system resource effectively, reduce the signaling consumption and the signaling transmission of system, the load of mitigation system.
Fig. 1 is the schematic flow sheet of the MBMS business transmitting method in the one embodiment of the invention.As shown in Figure 1, in this MBMS business transmitting method, mainly comprise the step that is described below:
Step 101 is provided with at least one grade (Level) zone in a MBSFN Area, the initial condition of each hierarchical region is state of activation or unactivated state.
In this step, being provided with of said hierarchical region can be to be provided with in advance, also can be to dynamically arrange.
Specifically, can in same MBSFN Area, one or more hierarchical regions be set in advance.For example; In technical scheme of the present invention; Can one or more hierarchical regions be set in advance according in the geographical position of each sub-district among the MBSFN Area, the information such as network load and adjacent area interference among the MBSFN Area at least one in said MBSFNArea.
In addition, can also dynamically arrange one or more hierarchical regions through MCE.For example, MCE can dynamically be divided into one or more hierarchical regions with said MBSFN Area according in the geographical position of each sub-district among the MBSFNArea, the information such as network load and adjacent area interference among the MBSFNArea at least one; Then, this MCE can send to each sub-district among this MBSFN Area with the dividing condition of above-mentioned hierarchical region through the hierarchical region configuration messages.
Wherein, can comprise in the said hierarchical region configuration messages: the information various information such as (for example, the class informations of the sign of hierarchical region and hierarchical region) of the hierarchical region under MBSFN Area identification information and each sub-district.Therefore, the dividing condition of the hierarchical region among this MBSFN Area can be known in each sub-district among the MBSFN Area according to above-mentioned hierarchical region configuration messages.
In addition, above-mentioned hierarchical region configuration messages can be the hierarchical region configuration messages that increases newly, also can be existing message in the system is improved the formed hierarchical region configuration messages in back.
In addition, the concrete number of above-mentioned set hierarchical region can preestablish according to actual conditions.Can comprise one or more sub-districts in each set hierarchical region, independently of one another between the different grade zone, promptly not overlapping between each hierarchical region.Therefore, though each sub-district can belong to one or more MBSFN Area; But in same MBSFN Area, a sub-district only belongs to some hierarchical regions wherein.
For example, Fig. 2 is the sketch map of hierarchical region set in the one embodiment of the invention.As shown in Figure 2, be provided with 3 hierarchical regions among the MBSFN Area in Fig. 2 altogether: hierarchical region 1, hierarchical region 2 and hierarchical region 3.Wherein, hierarchical region 1, hierarchical region 2 and hierarchical region 3 are independently of one another, promptly do not have overlapping part between 3 hierarchical regions.
After above-mentioned hierarchical region is set, also can the state of above-mentioned hierarchical region be provided with, for example, can the initial condition of each hierarchical region among the MBSFN Area be arranged to state of activation or unactivated state.Wherein, the MBSFN transmission all can be carried out in all sub-districts that are in the hierarchical region of said state of activation; Be in the hierarchical region of said unactivated state all sub-districts and all can not carry out the MBSFN transmission.
Need to prove, because the MBMS business of sub-district is that MCE provides, if therefore MCE does not temporarily provide corresponding M BMS professional, even the MBSFN transmission also will not carried out in the sub-district that then is in the hierarchical region of activated state; But the preparation of carrying out the MBSFN transmission will be carried out in the sub-district that is in the hierarchical region of state of activation, so that broadcast from the MBMS of MCE professional at any time.And be in the sub-district in the hierarchical region of unactivated state, and can not carry out the MBSFN transmission, the MBMS from MCE that does not also broadcast is professional.
In specific embodiment of the present invention, can the initial condition of each hierarchical region among the MBSFN Area all be arranged to unactivated state; Perhaps the initial condition of the hierarchical region of appointment among the MBSFN Area is arranged to state of activation, the initial condition of other hierarchical region of non-appointment is arranged to unactivated state.For example, can the initial condition of at least one hierarchical region among the MBSFNArea be arranged to unactivated state.
After being provided with of the initial condition of accomplishing above-mentioned hierarchical region, can the initial state information of above-mentioned hierarchical region be carried in the state information of hierarchical region, directly be stored among each sub-district and the MCE.Wherein, can comprise in the state information of said hierarchical region: the various information such as state of the hierarchical region under MBSFN Area identification information and each sub-district.
In addition; When the state of a hierarchical region changes (for example; This grade zone converts into and is in unactivated state from being in state of activation; Perhaps opposite), MCE can send to the sub-district in the hierarchical region adjacent with this grade zone in MBSFN Area through the hierarchical region status change message with the state information behind this grade area change; Be in the sub-district on border in the hierarchical region that perhaps can be changed by state, the neighbor cell in its adjacent rank zone sends the hierarchical region status change message that carries the state information behind this grade area change.Receive each sub-district of hierarchical region status change message, can change the state information of its hierarchical region of being stored of information updating according to this grade zone state.Wherein, can comprise in the said hierarchical region status change message: at least one in the various information such as the state of the hierarchical region behind MBSFNArea identification information, the change state and state information change indication.Wherein, said state information changes indication and can be used to represent that change has taken place the state that sends the hierarchical region of this indication.
In technical scheme of the present invention, above-mentioned hierarchical region status change message can be the hierarchical region status change message that increases newly, also can be existing message in the system is improved the formed hierarchical region status change message in back.
In addition, in specific embodiment of the present invention, each sub-district that is in the hierarchical region of unactivated state can receive the business information that MCE sends, and also can not receive the business information that MCE sends.Wherein, can comprise in the said business information: at least one in service identification, professional beginning/end (session start/session stop) message, business tine and the business datum.
After accomplishing above-mentioned setting; Owing to the MBSFN transmission is not all carried out in all sub-districts in the hierarchical region that is in unactivated state, therefore, when in MBSFN Area, carrying out the MBSFN transmission; As long as in this MBSFNArea, there is a hierarchical region to be in unactivated state; Just the available resources of system be can save greatly, and the signaling consumption and the signaling transmission of system, the integral body load of mitigation system significantly reduced.
Step 102 is in each sub-district of the hierarchical region of unactivated state, can be according to the MBSFN transmission that activates message activation self.
In technical scheme of the present invention; If in certain MBSFN Area, there is a hierarchical region to be in unactivated state; Then this is in each sub-district of the hierarchical region of unactivated state; Can transmit according to the MBSFN of corresponding activation message activation self, thereby make whole hierarchical region convert state of activation to from unactivated state.
Owing to be in each sub-district in the hierarchical region of unactivated state before not being activated, will do not carry out the MBSFN transmission, thereby can save a large amount of system's available resources.And when needs activate each sub-district in the above-mentioned hierarchical region; Said each sub-district again can be according to the MBSFN transmission of corresponding activation message activation self; BMS is professional for the transmission of the UE in these sub-districts corresponding M; Thereby can under the prerequisite of the available resources of saving system, guarantee the business continuance of UE as far as possible.
In technical scheme of the present invention, can use several different methods to realize above-mentioned step 102.Below will carry out detailed ground introduction to technical scheme of the present invention by way of example.
Implementation one,
When UE prepares that cell-of-origin from the hierarchical region that is in state of activation is switched or the Target cell of gravity treatment in the hierarchical region that is in unactivated state; And that is broadcasting in the hierarchical region under the said cell-of-origin that said UE receiving is professional and/or interested when professional; Each sub-district in the hierarchical region under the said Target cell is according to the MBSFN transmission that activates message activation self.
Specifically; When UE is in mobile status; This UE might move to the sub-district (Target cell) in another hierarchical region among the same MBSFN Area in the sub-district (cell-of-origin, i.e. sub-district, the current place of UE) from certain hierarchical region, need carry out the sub-district this moment and switch or gravity treatment.Before carrying out sub-district switching or gravity treatment; If the hierarchical region under the cell-of-origin is in state of activation; And broadcasting the professional and/or interested business that this UE is receiving in the hierarchical region under this cell-of-origin; And the affiliated hierarchical region of Target cell is in unactivated state, then can be through the corresponding MBSFN transmission (promptly activate the affiliated hierarchical region of Target cell, thereby make the hierarchical region under the Target cell convert state of activation into from unactivated state) that activates each sub-district in the affiliated hierarchical region of message activation Target cell; Therefore make UE after accomplishing switching or gravity treatment; Can in Target cell, proceed the professional MBSFN transmission of MBMS, thereby can in the system of saving available resources, guarantee the business continuance of UE as far as possible.
Implementation two,
Hierarchical region under sub-district, the current place of UE is in unactivated state; And other is in, and to broadcast said UE in the hierarchical region of state of activation interested when professional; Each sub-district in the hierarchical region under the sub-district, the current place of said UE can be according to the MBSFN transmission that activates message activation self.
Specifically, when UE is not moved, but the hierarchical region under the sub-district, the current place of this UE (can abbreviate current hierarchical region as, down with) when being in unactivated state, the MBSFN transmission is not all carried out in all sub-districts in the said current hierarchical region.But; If being in the hierarchical region of state of activation, other among the MBSFN Area under this current hierarchical region broadcasting the interested business of said UE; Then can (promptly activate current hierarchical region through the corresponding MBSFN transmission that activates each sub-district of this current hierarchical region of message activation; Thereby make current hierarchical region convert state of activation into from unactivated state), make the sub-district, the current place of UE that is in the current hierarchical region can carry out corresponding M BSFN transmission, thus can be so that UE receives its interested business in follow-up process; Thereby can in the system of saving available resources, guarantee the business continuance of UE as far as possible.
In addition, in technical scheme of the present invention, can use multiple mode to activate affiliated hierarchical region of above-mentioned Target cell and/or the hierarchical region under the sub-district, the current place of said UE.For example, can be each sub-district by the hierarchical region under the Target cell, the MBSFN transmission of the activation message activation self that sends according to sub-district, the current place of said UE (being the cell-of-origin) or MCE; Perhaps, can be each sub-district by the hierarchical region under the sub-district, the current place of said UE (being current hierarchical region), the MBSFN transmission of the activation message activation self that sends according to said UE sub-district, current place or MCE.
Fig. 3 is the schematic flow sheet of the MBMS business transmitting method of another embodiment of the present invention.As shown in Figure 3, this method can comprise:
Step 301 is provided with at least one hierarchical region in a MBSFN Area, the initial condition of each hierarchical region is state of activation or unactivated state.
The concrete implementation of this step can be identical with step 101 essence shown in Figure 1, repeats no more at this.
Step 302; When UE prepares that cell-of-origin from the hierarchical region that is in state of activation is switched or the Target cell of gravity treatment in the hierarchical region that is in unactivated state; And that is broadcasting in the hierarchical region under the said cell-of-origin that said UE receiving is professional and/or interested when professional; Each sub-district in the hierarchical region under the said Target cell is according to the MBSFN transmission that activates message activation self.
In technical scheme of the present invention, store the state information of hierarchical region in the said cell-of-origin, therefore, the relevant information in the hierarchical region under it can be known in the cell-of-origin, for example, is broadcasting which MBMS business etc. in this grade zone.In addition; When UE also is in the cell-of-origin; Professional and/or the interested business of this UE that this UE will report this UE receiving to this cell-of-origin through other status report messages of MBMS status report messages or redetermination; Therefore, the cell-of-origin can know whether broadcasting the professional and/or interested business that said UE is receiving in the hierarchical region under this cell-of-origin according to the message that UE reported.
In addition, in technical scheme of the present invention, can use several different methods to activate the affiliated hierarchical region of said Target cell.To be example below, technical scheme of the present invention will be carried out detailed introduction with two kinds of concrete implementations wherein.
For example, each sub-district in the hierarchical region under the said Target cell in the above-mentioned steps 302, according to the MBSFN transmission that activates message activation self, can realize through the step (not shown among Fig. 3) that is described below:
Step 3011, each sub-district in the hierarchical region of said cell-of-origin under said Target cell are sent and are activated message.
In this step; Owing to all store the state information of hierarchical region in each sub-district among the MBSFN Area; Therefore, said cell-of-origin can be according to the state information of above-mentioned hierarchical region, sends to each sub-district in the hierarchical region under the said Target cell with activating message.Preferable; Because same sub-district possibly belong to different MBSFN Area; Therefore; In order to know which MBSFN Area the hierarchical region under the above-mentioned cell-of-origin belongs to, and can carry MBSFN Area identification information in the said activation message in each sub-district in the hierarchical region that lets under the Target cell, in order to represent the MBSFN Area at the hierarchical region place under this cell-of-origin.
Step 3012, each sub-district in the hierarchical region under the said Target cell, the MBSFN of the activation message activation self that all sends according to said cell-of-origin transmits.
In this step; Because the MBSFN transmission of the activation message activation self that each sub-district in the hierarchical region under the said Target cell all will be sent according to said cell-of-origin; Therefore; After the MBSFN transmission of self is all activated in each sub-district in the hierarchical region under the said Target cell, the hierarchical region under this Target cell also will be in state of activation, thereby make the hierarchical region under this Target cell convert state of activation into from unactivated state.
By on can know, through above-mentioned step 3011～3012, can activate the hierarchical region under the said Target cell.
In addition, each sub-district in the hierarchical region under the said Target cell in the above-mentioned steps 302, according to the MBSFN transmission that activates message activation self, can also realize through the step (not shown among Fig. 3) that is described below:
Step 3021, said cell-of-origin sends a notification message to MCE.
In this step, can comprise in the said notification message: the sign of the hierarchical region under the said Target cell, the service identification that UE is receiving and at least one in the interested service identification of this UE.
Wherein, store the state information of hierarchical region in the said cell-of-origin, therefore, the sign of the hierarchical region under the said Target cell can be known in said cell-of-origin.In addition, when UE also is in the cell-of-origin, the professional and/or interested business of this UE that this UE can report this UE receiving to this cell-of-origin through other status report messages of MBMS status report messages or redetermination.
Step 3022, MCE is according to received notification message, and each sub-district of the hierarchical region under said Target cell is sent and is activated message.
Preferable, in this step, can carry MBSFN Area identification information in the said activation message, in order to represent the MBSFN Area at the hierarchical region place under the said cell-of-origin.
The activation message activation MBSFN transmission that send according to said MCE each sub-district of hierarchical region under the step 3023, said Target cell.
In this step, after each sub-district of the hierarchical region under the said Target cell receives that above-mentioned MCE sends activation message, all can activate the MBSFN transmission of message activation self according to this.Therefore, after the MBSFN transmission of self is all activated in each sub-district in the hierarchical region under the Target cell, the hierarchical region under this Target cell also will be in state of activation.
By on can know, through above-mentioned step 3021～3023, also can activate the hierarchical region under the said Target cell.
Fig. 4 is the schematic flow sheet of the MBMS business transmitting method of another embodiment of the present invention.As shown in Figure 4, this method can comprise:
Step 401 is provided with at least one hierarchical region in a MBSFN Area, the initial condition of each hierarchical region is state of activation or unactivated state.
The concrete implementation of this step can be identical with step 101 essence shown in Figure 1, repeats no more at this.
Step 402; Hierarchical region under sub-district, the current place of UE is in unactivated state; And other is in, and to broadcast said UE in the hierarchical region of state of activation interested when professional; Each sub-district in the hierarchical region under the sub-district, the current place of said UE can be according to the MBSFN transmission that activates message activation self.
In technical scheme of the present invention, the concrete implementation of the hierarchical region under the sub-district, the current place of the said UE of above-mentioned activation can have multiple.To be example below, technical scheme of the present invention will be introduced with two kinds of concrete implementations wherein.
For example, each sub-district in the hierarchical region under the sub-district, the current place of said UE in the above-mentioned steps 402, can realize through the step (not shown among Fig. 4) that is described below according to the MBSFN transmission that activates message activation self:
Step 4011, each sub-district in the hierarchical region of sub-district, the current place of said UE under it are sent and are activated message.
In this step; Owing to all store the state information of hierarchical region in each sub-district among the MBSFN Area; Therefore; Sub-district, the current place of said UE can be according to the state information of above-mentioned hierarchical region, sends to each sub-district in the hierarchical region under the sub-district, the current place of said UE with activating message.Preferable; Because same sub-district possibly belong to different MBSFN Area; Therefore; In order to know which MBSFN Area the hierarchical region under the sub-district, the current place of above-mentioned UE belongs to, and can carry MBSFN Area identification information in the said activation message in each sub-district in the hierarchical region that lets under the sub-district, the current place of said UE, in order to represent the MBSFN Area at the hierarchical region place under the sub-district, the current place of said UE.
Step 4012, each sub-district in the hierarchical region under the sub-district, the current place of said UE, the MBSFN of the activation message activation self that all sends according to sub-district, the current place of said UE transmits.
In this step; Because the MBSFN transmission of the activation message activation self that each sub-district in the hierarchical region under the sub-district, the current place of said UE all will be sent according to sub-district, the current place of said UE; Therefore; After the MBSFN transmission of self is all activated in each sub-district in the hierarchical region under the sub-district, the current place of said UE, the hierarchical region under the sub-district, the current place of this UE also will be in state of activation.
By on can know, through above-mentioned step 4011～4012, can activate the hierarchical region under the sub-district, the current place of said UE.
In addition, in technical scheme of the present invention, if having only a sub-district in the hierarchical region under the sub-district, the current place of UE; I.e. sub-district, the current place of this UE; At this moment, can not carry out above-mentioned steps 4011 and 4012, and directly activate the MBSFN transmission of self by sub-district, the current place of said UE; Also can activate the MBSFN transmission of self through carrying out above-mentioned steps 4011 and 4012, sub-district, the current place of promptly said UE can be given oneself to send and activate message, and activates the MBSFN transmission of message activation self according to this.
In addition, each sub-district in the hierarchical region under the sub-district, the current place of said UE in the above-mentioned steps 402, can also realize through the step (not shown among Fig. 4) that is described below according to the MBSFN transmission that activates message activation self:
Step 4021, sub-district, the current place of said UE sends a notification message to MCE.
In this step, can comprise in the said notification message: the sign of the hierarchical region under the sub-district, the current place of said UE, the service identification that UE is receiving and at least one in the interested service identification of this UE.
Wherein, store the state information of hierarchical region in the sub-district, the current place of said UE, therefore, the sign of the hierarchical region under it can be known in sub-district, the current place of said UE.In addition, UE can be through other status report messages of MBMS status report messages or redetermination, the professional and/or interested business of this UE that reports this UE receiving to sub-district, the current place of UE.Wherein, comprise in other status report messages of said MBMS status report messages or redetermination: the MBMS service identification of this UE.
In addition; Owing to generally all store the state information of hierarchical region among the MCE; So MCE can know that this notification message is sent by which sub-district according to the notification message that is received, and directly know the hierarchical region under this sub-district from the state information of the hierarchical region stored.Therefore, in above-mentioned notification message, also can not comprise the sign of the hierarchical region that sub-district, the current place of said UE is affiliated.
Step 4022, MCE is according to the said notification message that receives, and each sub-district of the hierarchical region under sub-district, the current place of said UE is sent and is activated message.
Preferable, in this step, can carry MBSFN Area identification information in the said activation message, in order to represent the MBSFN Area at the hierarchical region place under the sub-district, the current place of said UE.
The activation message activation MBSFN transmission that send according to said MCE each sub-district of hierarchical region under the step 4023, sub-district, the current place of said UE.
In this step, after the activation message that above-mentioned MCE sends is received in each sub-district of the hierarchical region under the sub-district, the current place of said UE, all can activate the MBSFN transmission of message activation self according to this.Therefore, after the MBSFN transmission of self is all activated in each sub-district in the hierarchical region under the sub-district, the current place of UE, the hierarchical region hierarchical region under the sub-district, the current place of this UE also will be in state of activation.
By on can know, through above-mentioned step 4021～4023, also can activate the hierarchical region under the sub-district, the current place of said UE.
In addition; In technical scheme of the present invention; In above-mentioned steps 3022 or 4022; MCE can promptly according to this notification message, send activation message to each sub-district of the hierarchical region under the said Target cell or each sub-district of the hierarchical region under the sub-district, the current place of said UE after receiving a notification message; Also can be not send activation message immediately, but when MCE receive the notification message that activates same hierarchical region outnumber preset threshold value the time, MCE sends to each sub-district of said hierarchical region and activates message.
In the later case, a threshold value need be set in advance.After above-mentioned threshold value was set, MCE was not after receiving a notification message, just sent according to this notification message immediately and activated message; But receive the notification message of the same hierarchical region of activation of some at this MCE after; Redispatch and activate message accordingly, thereby can when the request that activates certain hierarchical region reach some, activate this grade zone again; Thereby can avoid activating prematurely hierarchical region; Under the prerequisite of saving system resource, guarantee professional continuity, to save system resource and to keep obtaining certain balance between the business continuance as far as possible.
Therefore, in technical scheme of the present invention, the value of above-mentioned threshold value is the integer greater than 1, and concrete numerical value can be provided with according to practical situations in advance, and the present invention does not do qualification at this.
Further, in technical scheme of the present invention, be in each sub-district of the hierarchical region of state of activation, also can stop the MBSFN transmission of self according to deexcitation message.
Specifically, in technical scheme of the present invention, the initial condition of each hierarchical region can be configured to state of activation or unactivated state.And can know according to the above-mentioned technical scheme that provides; Be in each sub-district of the hierarchical region of unactivated state; Can transmit according to the MBSFN that activates message activation self, thereby make this grade zone convert state of activation to, to guarantee the business continuance of UE as far as possible from unactivated state.
Yet; In technical scheme of the present invention, in some cases, can also carry out deactivating operation to the hierarchical region that some has been in state of activation through deexcitation message; Make this grade zone convert unactivated state to, thereby further save the available resources of system from state of activation.
For example; When the business that does not all have UE receiving in each sub-district in the hierarchical region that is in state of activation and UE interested when professional; Each sub-district in the said hierarchical region can stop the MBSFN transmission (being the MBSFN transmission of deexcitation self) of self according to deexcitation message; Thereby make this grade zone convert unactivated state to, realize deexcitation this grade zone from state of activation.
In technical scheme of the present invention, can use several different methods to realize deexcitation to the hierarchical region that is in state of activation.Fig. 5 shows each sub-district in the above-mentioned hierarchical region stops the MBSFN transmission of self according to deexcitation message method flow sketch map.As shown in Figure 5, this method can realize through following steps:
Step 501, when business that does not have UE receiving in the sub-district in the hierarchical region that is in state of activation and the interested business of UE, the deexcitation notification message is sent to MCE in this sub-district.
In technical scheme of the present invention; Because UE will be through other status report messages of MBMS status report messages or redetermination; Professional and/or the interested business of this UE that reports this UE receiving to sub-district, the current place of this UE; Therefore, be in MBMS status report messages that each sub-district in the hierarchical region of state of activation all can report according to UE or other status report messages of redetermination and know business and the interested business of UE that whether has UE receiving in this sub-district.If the business and the interested business of UE that have no a UE receiving in certain sub-district, then the deexcitation notification message will be sent to MCE in this sub-district.MCE can be known business and the interested business of UE that has not had UE receiving in this sub-district according to the deexcitation notification message that is received.
Preferable, because same sub-district possibly belong to different MBSFN Area, therefore, can carry MBSFN Area identification information in the said deexcitation notification message, in order to represent the said MBSFN Area that is in the hierarchical region place of state of activation.
Step 502, when the number that receives the notification message of the same hierarchical region that is in state of activation of deexcitation as MCE reached preset threshold value, MCE sent deexcitation message in all sub-districts in the said hierarchical region that is in state of activation.
Wherein, the value of above-mentioned threshold value is the integer greater than 0, and its maximum is the sum of the sub-district in the said hierarchical region that is in state of activation.Concrete numerical value can be provided with according to practical situations in advance, and the present invention does not do qualification at this.
Preferable, because same sub-district possibly belong to different MBSFN Area, therefore, can carry MBSFN Area identification information in the said deexcitation message, in order to represent the said MBSFN Area that is in the hierarchical region place of state of activation.
Step 503, said each sub-district that is in the hierarchical region of state of activation stops the MBSFN transmission of self according to the deexcitation message that is received.
In this step; Said each sub-district that is in the hierarchical region of state of activation all will stop the MBSFN transmission of self according to the activation message that is received; Therefore; After said each sub-district that is in the hierarchical region of state of activation all stops the MBSFN transmission of self, this hierarchical region that is in state of activation also will be in unactivated state, thereby realize the above-mentioned deexcitation that is in the hierarchical region of state of activation.
In addition, in technical scheme of the present invention, can also in MBSFN Area, hierarchical region be set, and directly realize the activation and/or the deexcitation of sub-district.Below will be explained with the mode of embodiment.
Fig. 6 is the schematic flow sheet of the MBMS business transmitting method of another embodiment of the present invention.As shown in Figure 6, second kind of MBMS business transmitting method among the present invention comprises the step that is described below:
Step 601, the initial condition of each sub-district among MBSFN Area is set to sub-district state of activation or non-sub-district state of activation.
Wherein, the MBSFN transmission can be carried out in the sub-district that is in said sub-district state of activation; The MBSFN transmission can not be carried out in the sub-district that is in said non-sub-district state of activation.
Need to prove,,, also will not carry out the MBSFN transmission even then be in the sub-district of sub-district activated state if therefore MCE does not temporarily provide corresponding M BMS professional because the MBMS business of sub-district is that MCE provides; But the preparation of carrying out the MBSFN transmission will be carried out in the sub-district that is in the sub-district state of activation, so that broadcast from the MBMS of MCE professional at any time.And be in the sub-district of non-sub-district state of activation, and can not carry out the MBSFN transmission, the MBMS from MCE that does not also broadcast is professional.
In specific embodiment of the present invention, can the initial condition of each sub-district among the MBSFN Area all be arranged to non-sub-district state of activation; Perhaps the initial condition of the sub-district of appointment among the MBSFN Area is arranged to the sub-district state of activation, the initial condition of other sub-district of non-appointment is arranged to non-sub-district state of activation.For example, can the initial condition of at least one sub-district among the MBSFN Area be arranged to non-sub-district state of activation.
After being provided with of the initial condition of accomplishing above-mentioned sub-district, can the initial state information of above-mentioned sub-district be carried in the state information of sub-district, directly be stored among each sub-district and the MCE.Wherein, can comprise in the state information of said sub-district: the various information such as state of MBSFN Area identification information and each sub-district.In addition, the state information of all sub-districts among this MBSFN Area can be stored in each sub-district, also the state information of self and the state information of neighbor cell can be only stored.
In addition; When the state of a sub-district changes (for example; This sub-district converts into and is in non-sub-district state of activation from being in the sub-district state of activation; Perhaps opposite), MCE can change message through cell status with the state information behind this cell change and send to sub-district adjacent with this sub-district in MBSFN Area; The sub-district that perhaps can be changed by state, the cell status that sends the state information after carrying said cell change to its neighbor cell changes message.Receive each sub-district of cell status change message, can change the state information of its sub-district of being stored of information updating according to this cell status.Wherein, said cell status changes in the message and can comprise: at least one in the various information such as the state of the sub-district behind MBSFN Area identification information, the change state and state information change indication.
In technical scheme of the present invention, it can be that the cell status that increases newly changes message that above-mentioned cell status changes message, also can be existing message in the system to be improved the formed cell status in back change message.
In addition, in specific embodiment of the present invention, each sub-district that is in non-sub-district state of activation can receive the business information that MCE sends, and also can not receive the business information that MCE sends.Wherein, can comprise in the said business information: at least one in service identification, professional beginning/end (session start/session stop) message, business tine and the business datum.
After accomplishing above-mentioned setting; Do not carry out the MBSFN transmission owing to be in the sub-district of non-sub-district state of activation, therefore, when in MBSFN Area, carrying out the MBSFN transmission; As long as in this MBSFN Area, there is a sub-district to be in non-sub-district state of activation; Just can save the available resources of system, and reduce the signaling consumption and the signaling transmission of system, the integral body load of mitigation system.
Step 602 is in the sub-district of non-sub-district state of activation, can be according to the MBSFN transmission that activates message activation self.
In this step; If in certain MBSFN Area, there is a sub-district to be in non-sub-district state of activation; Then this is in the sub-district of non-sub-district state of activation; Can transmit according to the MBSFN of corresponding activation message activation self, thereby make that state of activation converts the sub-district state of activation to from non-sub-district in this sub-district.
Because the MBSFN transmission before not being activated, will not carried out in the sub-district that is in non-sub-district state of activation, thereby the available resources of system have been saved.And when needs activated this sub-district, this sub-district can be that the transmission of the UE in this sub-district corresponding M BMS is professional according to the MBSFN transmission that activates message activation self again, thereby can under the prerequisite of the available resources of the system of saving, guarantee the business continuance of UE as far as possible.
In technical scheme of the present invention, can use several different methods to realize above-mentioned step 602.Below will carry out detailed ground introduction to technical scheme of the present invention by way of example.
Implementation one,
When UE prepare to switch from the cell-of-origin that is in the sub-district state of activation or gravity treatment to the Target cell that is in non-sub-district state of activation; And that is broadcasting in the said cell-of-origin that said UE receiving is professional and/or interested when professional, and said Target cell is according to the MBSFN transmission that activates message activation self.
In above-mentioned implementation one, before UE carries out sub-district switching or gravity treatment, if the cell-of-origin is in the sub-district state of activation; And broadcasting the professional and/or interested business that this UE is receiving in this cell-of-origin; And Target cell is in non-sub-district state of activation, then can transmit through the corresponding MBSFN that activates the message activation Target cell, thereby make that state of activation converts the sub-district state of activation into to Target cell from non-sub-district); Therefore make UE after accomplishing switching or gravity treatment; Can in Target cell, proceed the professional MBSFN transmission of MBMS, thereby can in the system of saving available resources, guarantee the business continuance of UE as far as possible.
Implementation two,
When sub-district, the current place of UE is in non-sub-district state of activation; And it is interested when professional to broadcast said UE in the sub-district that is in the sub-district state of activation among the MBSFN Area under this sub-district, and sub-district, the current place of said UE can be activated or according to the MBSFN transmission that activates message activation self automatically.
In above-mentioned implementation two, when UE is not moved, but sub-district, the current place of this UE is when being in non-sub-district state of activation, and the MBSFN transmission is not carried out in sub-district, the current place of said UE, thereby has saved the available resources of system.Yet; If being in the sub-district of sub-district state of activation, other among the MBSFN Area under the sub-district, the current place of this UE broadcasting the interested business of said UE; Then can be through the corresponding MBSFN transmission that activates sub-district, the current place of this UE of message activation; Perhaps activate the MBSFN transmission of self automatically, make that state of activation converts the sub-district state of activation into to sub-district, the current place of this UE from non-sub-district, in follow-up process, receive its interested business thereby be convenient to UE by sub-district, the current place of this UE; Thereby can in the system of saving available resources, guarantee the business continuance of UE as far as possible.
In addition, in technical scheme of the present invention, can use multiple mode to activate above-mentioned Target cell and/or sub-district, the current place of said UE.For example, can be by Target cell, the MBSFN transmission of the activation message activation self that sends according to sub-district, the current place of said UE (being the cell-of-origin) or MCE; Perhaps, can be by sub-district, the current place of said UE, the MBSFN transmission of the activation message activation self that activates automatically or send according to MCE.
Fig. 7 is the schematic flow sheet of the MBMS business transmitting method of another embodiment of the present invention.Of Fig. 7, this method can comprise:
Step 701, the initial condition of each sub-district among MBSFN Area is set to sub-district state of activation or non-sub-district state of activation.
The concrete implementation of this step can be identical with step 601 essence shown in Figure 6, repeats no more at this.
Step 702; When UE prepare to switch from the cell-of-origin that is in the sub-district state of activation or gravity treatment to the Target cell that is in non-sub-district state of activation; And that is broadcasting in the said cell-of-origin that said UE receiving is professional and/or interested when professional, and said Target cell is according to the MBSFN transmission that activates message activation self.
In technical scheme of the present invention, can use several different methods to activate said Target cell.To be example below, technical scheme of the present invention will be carried out detailed introduction with two kinds of concrete implementations wherein.
For example, the said Target cell in the above-mentioned steps 702 can be realized through the step (not shown among Fig. 7) that is described below according to the MBSFN transmission that activates message activation self:
Step 7011, said cell-of-origin are sent to said Target cell and are activated message.
In this step, owing to all store the cell status information of each sub-district among the MBSFN Area in each sub-district among the MBSFN Area, therefore, said cell-of-origin can will be activated message and send to said Target cell according to the state information of above-mentioned sub-district.Preferable; Because same sub-district possibly belong to different MBSFN Area, therefore, in order to let Target cell know which MBSFN Area above-mentioned cell-of-origin belongs to; Can carry MBSFN Area identification information in the said activation message, in order to represent the MBSFN Area at this place, cell-of-origin.
Step 7012, said Target cell is according to the MBSFN transmission of said activation message activation self.
In this step, because said Target cell will be according to the MBSFN transmission of said activation message activation self, therefore, after said Target cell activates the MBSFN transmission of self, this Target cell will be in the sub-district state of activation.
By on can know, through above-mentioned step 7011～7012, can activate said Target cell.
In addition, the said Target cell in the above-mentioned steps 702 can also be realized through the step (not shown among Fig. 7) that is described below according to the MBSFN transmission that activates message activation self:
Step 7021, said cell-of-origin sends a notification message to MCE.
In this step, can comprise in the said notification message: at least one in service identification that the sign of said Target cell, UE are receiving and the interested service identification of this UE.
Wherein, store the state information of each sub-district in the said cell-of-origin or only store the state information of self and the state information of neighbor cell, therefore, the state information of said Target cell can be known in said cell-of-origin.In addition, when UE also was in the cell-of-origin, this UE can be through other status report messages of MBMS status report messages or redetermination, the professional and/or interested business of this UE that reports this UE receiving to this cell-of-origin.Wherein, comprise in other status report messages of said MBMS status report messages or redetermination: the MBMS service identification of this UE.
Step 7022, MCE sends activation message according to received notification message to said Target cell.
Preferable, in this step, can carry MBSFN Area identification information in the said activation message, in order to represent the MBSFN Area at place, said cell-of-origin.
Step 7023, said Target cell is according to the activation message activation MBSFN transmission that is received.
In this step, after said Target cell is received above-mentioned activation message, can activate the MBSFN transmission of message activation self according to this.Therefore, after Target cell activates the MBSFN transmission of self, this Target cell also will be in the sub-district state of activation.
By on can know, through above-mentioned step 7021～7023, also can activate said Target cell.
Fig. 8 is the schematic flow sheet of the MBMS business transmitting method of another embodiment of the present invention.Of Fig. 8, this method can comprise:
Step 801, the initial condition of each sub-district among MBSFN Area is set to sub-district state of activation or non-sub-district state of activation.
The concrete implementation of this step can be identical with step 601 shown in Figure 6, repeats no more at this.
Step 802; When sub-district, the current place of UE is in non-sub-district state of activation; And it is interested when professional to broadcast said UE in the sub-district that is in the sub-district state of activation among the MBSFN Area under this sub-district, and sub-district, the current place of said UE is activated or according to activating message or activating self MBSFN transmission automatically.
In technical scheme of the present invention, the concrete implementation of sub-district, the current place of the said UE of above-mentioned activation can have multiple.To be example below, technical scheme of the present invention will be introduced with two kinds of concrete implementations wherein.
For example, the sub-district, the current place of said UE in the above-mentioned steps 802 is activated the MBSFN transmission of self automatically, can be (not shown among Fig. 8):
Step 8011, the MBSFN transmission of self is activated automatically according to the professional and/or interested business of this UE that is receiving that UE reported in this sub-district in sub-district, the current place of said UE.
In this step, UE can be through other status report messages of message such as MBMS status report messages or redetermination, the professional and/or interested business of this UE that reports this UE receiving to sub-district, the current place of UE.Wherein, in the said MBMS status report messages or other status report messages of redetermination comprise: the MBMS service identification of this UE.Therefore; After the professional and/or interested business of this UE that is receiving that UE reported that sub-district, the current place of said UE can be in receiving this sub-district; Automatically activate the MBSFN transmission of self; Thereby for the UE in this sub-district provides MBSFN transmission, sub-district, the current place of this UE will convert the sub-district state of activation into from non-sub-district state of activation.
By on can know, through above-mentioned step 8011, can activate sub-district, the current place of said UE.
In addition, (not shown among Fig. 8) can also be realized through the step that is described below according to the MBSFN transmission that activates message activation self in the sub-district, the current place of said UE in the above-mentioned steps 802:
Step 8021, sub-district, the current place of said UE sends a notification message to MCE.
In this step, can comprise in the said notification message: at least one in the sign of sub-district, the current place of said UE, the service identification that UE is receiving and the interested service identification of this UE.
Wherein, UE in the sub-district, the current place of said UE can report the MBMS service identification of the professional and/or interested business of this UE that comprises that this UE is receiving through other status report messages of MBMS status report messages or redetermination to sub-district, the current place of this UE.
Step 8022, MCE sends activation message according to the said notification message that receives to sub-district, the current place of said UE.
Preferable, in this step, can carry MBSFN Area identification information in the said activation message, in order to represent the MBSFN Area at place, sub-district, the current place of said UE.
Step 8023, sub-district, the current place of said UE is according to the activation message activation MBSFN transmission that is received.
In this step, after above-mentioned activation message is received in sub-district, the current place of said UE, can activate the MBSFN transmission of message activation self according to this, thereby make that state of activation converts the sub-district state of activation into to sub-district, the current place of this UE from the sub-district.
By on can know, through above-mentioned step 8021～8023, also can activate sub-district, the current place of said UE.
Further, in technical scheme of the present invention, be in the sub-district of sub-district state of activation, also can stop or stopping the MBSFN transmission of self automatically according to the deexcitation message that is received.
Specifically, in technical scheme of the present invention, the initial condition of each sub-district can be configured to sub-district state of activation or non-sub-district state of activation.And can know according to the above-mentioned technical scheme that provides; Be in the sub-district of non-sub-district state of activation; Can transmit according to the MBSFN that activates message activation self, thereby make that state of activation converts the sub-district state of activation to from non-sub-district in this sub-district, to guarantee the business continuance of UE as far as possible.
Yet; In technical scheme of the present invention; In some cases, the sub-district that is in the sub-district state of activation can also be carried out deactivating operation automatically, or carries out deactivating operation according to deexcitation message; Make that state of activation converts non-sub-district state of activation to from the sub-district in this sub-district, thereby further save the available resources of system.
For example; When the business that does not have UE receiving in the sub-district that is in the sub-district state of activation and UE interested when professional; Said sub-district can stop or stopping according to deexcitation message the MBSFN transmission (being the MBSFN transmission of deexcitation self) of self automatically; Thereby make that state of activation converts non-sub-district state of activation to from the sub-district in this sub-district, realize deexcitation this sub-district.
In technical scheme of the present invention, can use several different methods to realize deexcitation to the sub-district that is in the sub-district state of activation.
For example, Fig. 9 illustrates the sub-district that is in state of activation in the another embodiment of the present invention stops the MBSFN transmission of self according to deexcitation message method flow sketch map.As shown in Figure 9, this method can comprise:
Step 901, when business that does not have UE receiving in the sub-district that is in the sub-district state of activation and the interested business of UE, the deexcitation notification message is sent to MCE in this sub-district.
In technical scheme of the present invention; Because UE will be through other status report messages of MBMS status report messages or redetermination; Professional and/or the interested business of this UE that reports this UE receiving to sub-district, the current place of this UE; Therefore, be in MBMS status report messages that the sub-district of sub-district state of activation can report according to UE or other status report messages of redetermination and know business and the interested business of UE that whether has UE receiving in this sub-district.If the business and the interested business of UE that have no a UE receiving in the sub-district, then the deexcitation notification message will be sent to MCE in this sub-district.MCE can be known business and the interested business of UE that has not had UE receiving in this sub-district according to the deexcitation notification message that is received.
Preferable, because same sub-district possibly belong to different MBSFN Area, therefore, can carry MBSFN Area identification information in the said deexcitation notification message, in order to represent the said MBSFN Area that is in the place, sub-district of sub-district state of activation.
Step 902, when MCE received the deexcitation notification message, MCE sent deexcitation message to the said sub-district that is in the sub-district state of activation.
Preferable, because same sub-district possibly belong to different MBSFN Area, therefore, can carry MBSFN Area identification information in the said deexcitation message, in order to represent the said MBSFN Area that is in the place, sub-district of state of activation.
Step 903, the said sub-district that is in the sub-district state of activation stops the MBSFN transmission of self according to the deexcitation message that is received.
In this step; The said sub-district that is in the sub-district state of activation will stop the MBSFN transmission of self according to the activation message that is received; Thereby make that state of activation converts non-sub-district state of activation into from the sub-district in the sub-district, thereby realized the above-mentioned deexcitation that is in the sub-district of sub-district state of activation.
The MBSFN transmission that above-mentioned sub-district stops self automatically, can realize through following steps (not shown among Fig. 9):
Step 9021, when business that does not have UE receiving in the sub-district that is in the sub-district state of activation and the interested business of UE, said sub-district stops the MBSFN transmission of self automatically.
In this step; Because UE will be through other status report messages of MBMS status report messages or redetermination; Professional and/or the interested business of this UE that reports this UE receiving to sub-district, the current place of this UE; Therefore, be in MBMS status report messages that the sub-district of sub-district state of activation can report according to UE or other status report messages of redetermination and know business and the interested business of UE that whether has UE receiving in this sub-district.If the business and the interested business of UE that have no a UE receiving in the sub-district, then this sub-district will stop the MBSFN transmission of self automatically, thereby realize the above-mentioned deexcitation that is in the sub-district of sub-district state of activation.
In addition; In order to let network side for UE business continuance is provided better; UE can be through MBMS status report messages or redetermination other status report messages to network side (for example; Sub-district, the current place of UE) the professional and/or interested business of this UE that reports this UE receiving, thus business and the interested business that network side knows that UE is receiving made.Wherein, comprise in other status report messages of said MBMS status report messages or redetermination: the MBMS service identification of this UE.And said MBMS service identification comprises: service identification that UE is receiving and/or the interested service identification of this UE.Concrete report method can have various ways, for example, periodically reports, Event triggered reports (as: in beginning and/or finish to accept to report when certain is professional), reports command report etc. according to network side.
Further; In technical scheme of the present invention, the business that also will receive this UE that UE reports is distinguished with the interested business of this UE, makes network side can know that which business is the business that this UE is receiving; Which is the interested business of this UE; Thereby more suitably cell reselection priority can be provided for the UE that is in Idle state, perhaps can be the UE that is in connected state and select more suitably switching target small area, so that better business continuance is provided for UE.
Therefore, in technical scheme of the present invention, when UE reports its business professional and/or interested that is receiving, can distinguish business that is receiving and the interested business that said UE reports through the type of service flag.
In technical scheme of the present invention, can use several different methods that business that is receiving and interested business that the type of service flag reports to distinguish said UE are set.To be example below, distinguish the business that is receiving that said UE reports and the method for interested business describes in detail through the type of service flag above-mentioned with two kinds of concrete methods to set up wherein.
The method to set up one of type of service flag:
In a professional reporting message, the type of service flag that a length is 1 bit (bit) is set, be used for representing the business whether business that UE reports exists this UE receiving; If the business that exists UE receiving in the message that UE reported then is arranged on the service identification (ID) of the said business that is receiving the first place of the service identification tabulation that this UE reports in the said professional reporting message.
