By using the invention, the network side can accurately count the user numbers receiving the MBMS service in the cell in order to determine the load bearing mode, and reduce power consumption.
Description
Technical field
The present invention relates to the realization technology of multimedia broadcast/group broadcast service (MBMS), particularly a kind of network side knows that the user receives the method for MBMS service conditions.
Background technology
Multicast and broadcasting are a kind of technology that transmits data from a data source to a plurality of targets.In traditional mobile network, cell broadcaste service (CBS:Cell Broadcast Service) allows low bit rate data to share broadcast channel to all users' transmissions by the sub-district, belongs to information series business.
Now, people no longer are satisfied with phone and messaging service to the demand of mobile communication, fast development along with Internet, a large amount of multimedia services emerge, the some of them applied business requires a plurality of users can receive identical data simultaneously, as video request program, television broadcasting, video conference, online education, interactive game etc.These mobile multi-media services are compared with general data, have characteristics such as data volume is big, longer duration, delay sensitive.Present IP multicasting technology only is applicable to wired IP network, is not suitable for the mobile network, because the mobile network has particular network structure, functional entity and wave point, these are all different with wired IP network.
In order to effectively utilize mobile network resource, the WCDMA/GSM global standardsization organize 3GPP to propose multimedia broadcast/multicast service (MBMS:Multimedia Broadcast/Multicast Service), in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, the utilance of the interface resource of especially eating dishes without rice or wine.The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.
In order to support the MBMS business, increased mobile network functional entity---broadcast multicast service center BM-SC among the mobile network newly, it is content provider's a inlet, be used for authorizing and initiating the MBMS bearer service at mobile network, and plan transmits the MBMS content to schedule.In addition, functional entitys such as subscriber equipment (UE), land radio access web (UTRAN), GERAN, SGSN, GGSN strengthen, and have increased the relevant function of MBMS.
Such network configuration is referring to Fig. 1, and Fig. 1 is for supporting the wireless network architecture schematic diagram of multicast/broadcast business.Wherein, broadcast/multicast service center (BM-SC) is passed through Gmb interface or Gi interface and gateway general packet radio service (GPRS) support node (GGSN, Gateway GPRS SupportNode) and is linked to each other, and a BM-SC can link to each other with a plurality of GGSN; GGSN links to each other by Gn/Gp interface and Serving GPRS Support Node (SGSN, Serving GPRS Support Node), and a GGSN can link to each other with a plurality of SGSN; SGSN can link to each other with universal mobile telecommunications system (UMTS) land radio access web (UTRAN) by the Iu interface, UTRAN links to each other with communication terminal by the Uu interface then, SGSN also can strengthen wireless access network (GERAN) by Iu/Gb interface and global system for mobile communications (GSM) and link to each other, and GERAN links to each other with communication terminal by Um Interface then.
MBMS comprises multicast pattern and broadcast mode.The distinctive points of multicast service and broadcasting service only is: multicast service only sends corresponding information to the user who has subscribed to some information, and the broadcasting service then user of all in wireless network sends information.Multicast pattern needs user's corresponding multicast group of contracting, and carries out activation of service, and produces corresponding charge information.Because it is different that multicast and broadcast mode exist, cause also difference of its operation flow on business demand.
The user receives the entire flow of certain MBMS broadcasting service referring to Fig. 2, as shown in Figure 2, this flow process comprises: service statement (Service announcement), session begin (Session Start), MBMS notice (MBMS notification), transfer of data (Data transfer), conversation end (Session Stop) process.
Wherein, Service announcement process is used for by the current service that can provide of BM-SC declaration.
In the Session Start process, BM-SC is ready to transfer of data, and informing network is set up the bearing resource of corresponding core net (CN) and universal land radio access web (UTRAN).
MBMS notification process is used to notify UE MBMS multicast conversation to be about to begin.
In the Data transfer process, BM-SC transfers data to UE by the bearing resource that session begins to set up in the process.
The bearing resource that Session Stop process is used for Session Start process is set up discharges.
In broadcasting service, all preserve the bearer context of this MBMS business in each MBMS service node, this bearer context is activated in Session Start process, in Session Stop process by deexcitation.
The user receives the entire flow of certain MBMS multicast service referring to Fig. 3, as shown in Figure 3, this flow process comprises: subscription (Subscription), service statement (Service announcement), adding (Joining), session begin (Session Start), MBMS notice (MBMS notification), transfer of data (Data transfer), conversation end (Session Stop) and leave (Leaving) process.
Wherein, the Subscription process is used for allowing the user subscribe to required MBMS service in advance.
Service announcement process is used for by the current service that can provide of BM-SC declaration.
The Joining process is a MBMS activating multicast service process, UE is in the Joining process, informing network self is ready to become the member of current multicast group, receive corresponding professional multicast packet, this Joining process can be created the MBMS UE context of record UE information in the UE of network and adding multicast group.
In the Session Start process, BM-SC is ready to transfer of data, and informing network is set up the bearing resource of corresponding CN and UTRAN.
MBMS notification process is used to notify UE MBMS multicast conversation to be about to begin.
In the Data transfer process, BM-SC transfers data to UE by the bearing resource that session begins to set up in the process.
The bearing resource that Session Stop process is used for Session Start process is set up discharges.
The Leaving process makes the subscriber in the group leave multicast group, i.e. user's receiving multicast data no longer, and this process can be with corresponding MBMS UE context deletion.
The MBMS business has two kinds of service bearer modes when transmitting between UTRAN and UE: put multiple spot (PTM) pattern and point-to-point (PTP) pattern.The PTM pattern sends identical data by MBMS point-to-multipoint service channel (MTCH), and all add multicast service or can receive the interested UE of broadcasting service; Ptp mode sends data by dedicated transmission channel (DTCH), has only a corresponding UE to receive.
Determine that the key factor that the professional PTP of employing of MBMS still is the PTM bearing mode is: RNC is by adding up the number of users of this MBMS business of reception that obtains in the sub-district.In RNC, a record MBMS business contexts (MBMS Service Context) is arranged, wherein comprised and be in RRC Connected, the user record of PMM-Connected state at each MBMS business.The process that statistics receives the number of users of this MBMS business is counting (Counting) process, be exactly that RNC sends the Counting notification message to UE specifically, add this professional UE and return the Counting response message to RNC, RNC will return this professional Counting response message of reception and record among the MBMS ServiceContext, by the number of users among the statistics MBMS Service Context, obtain receiving in the sub-district user of this MBMS business.If number of users will use the PTM bearing mode so greater than certain predetermined thresholding, promptly use the common signal channel transmission; Otherwise use the PTP mode, for each user sets up a dedicated channel MBMS transmission business.
RNC not only carried out the Counting process before the professional transmission of MBMS, count the user that will receive this MBMS business, bearing mode according to the definite MBMS business that will send of this number, but also can in the professional transmission course of MBMS, carry out Counting, count the user who receives this MBMS business, determine whether needs change bearing mode according to this number.
In fact, the professional number that UE can add simultaneously can be many, but the business that can receive simultaneously but is very limited.For the UE of some low abilities, we can say basically simultaneously can only receive a MBMS business.
At present, when if UE selects between two MBMS business that provide simultaneously, one of them business has been used point-to-point bearing mode, because the link of a special use is arranged between UE and the network side, therefore UE is easy to send relevant business information to network side, and network side also just can have one to understand clearly for user's situation.Specifically, UE revises response (MBMS MODIFICATION REQUEST) by RRC message MBMS, the association requests of UE is sent to network side, the request network side takes certain measure to improve the ability that UE preferentially receives MBMS business or session (session), for UTRAN, the MBMS business is to embody with the form of a plurality of session.If UE can be according to the priority level of business under the CELL-DCH state, decision whether need to the network side feedback whether set up/keep/removes this special use connection.
But, if several professional uses that network side provides simultaneously all is under the situation of the connection of arriving multiple spot:
Because Idle, the UE of URA-PCH and CELL-PCH state can not use up channel, therefore, can't get in touch this moment with network side, their s own situation and professional relevant information comprise: the ability of UE reception MBMS service priority, UE reception MBMS business, the MBMS business that UE is receiving, MBMS business that the UE preparation receives or the like receive MBMS service conditions information and just can't be delivered to network.As seen, the UE of these states is in which business of reception, their ability is known nothing at this moment as situation network side how, because knowing to add at present, network side what do not have can receive this business among certain professional UE on earth like this, can only be that all these users are all counted, so in fact be exactly to be defaulted as the user that all users are Extra Sensory Perceptions.The result can cause naturally for the mistake that receives certain service-user counting number.
Selecting bearing mode is in order to save Radio Resource better, and the selection of bearing mode mistakenly, in other words, point-to-point carrying changes some the waste that multiple spot will cause the more power resource into, and counting process role for network can reduce greatly.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of network side to know that the user receives the method for MBMS service conditions, use this method and make network side can receive the situation of MBMS business, determine the bearing mode of MBMS business, reduce the power resource waste according to the user.
For achieving the above object, technical scheme of the present invention specifically is achieved in that

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to accompanying drawing two preferred embodiments that develop simultaneously, the present invention is described in more detail.
This network side of the present invention knows that the user receives the method for MBMS service conditions, UE receive that network side sends will or just behind the business control information of MBMS transmission business, business control information and/or self current working condition according to receiving report network side with own service reception condition information by ascending resource.
Professional reception condition information of the present invention can comprise: the user sets in advance and is stored in reception MBMS service priority table among the UE, UE and receives the ability of MBMS business, the MBMS business that UE is receiving, MBMS business, the user that UE prepares to receive and whether refuse one or more MBMS business, the professional reception condition information of the multiple MBMS of a kind of information wherein or combination in any; Or/and the reception condition information of non-MBMS business.
Below two preferred embodiments are described respectively.
First preferred embodiment:
Referring to Fig. 4, Fig. 4 is the process chart of the inventive method first preferred embodiment.In the present embodiment, the professional reception condition information of the MBMS that UE will report comprises at least: receive the ability that MBMS service priority table and UE receive the MBMS business.This flow process may further comprise the steps:
Step 401, UE receives network side and sends by Common Control Channel, and a kind of control information of MBMS business will be provided in the PTM mode.
Step 402, UE judges self whether to receive the professional or non-MBMS business of another or a plurality of MBMS, if then execution in step 403; Otherwise execution in step 408.
Step 403, UE judges whether self-ability can receive this MBMS business simultaneously, if can, execution in step 404; Otherwise execution in step 405.
Step 404 continues to carry out the MBMS business in the professional or non-MBMS business of the MBMS that is receiving and this control information, process ends.
Step 405, if the user receiving is one or more MBMS business, whether the priority of then judging the MBMS business of indicating in the control information is than the MBMS service priority height that is receiving, if then execution in step 406; Otherwise, execution in step 409.
If in the business of the current reception of user, not comprising the MBMS business, is other non-MBMS business, and then whether the user need determine to transfer to and receive MBMS or receive two types business simultaneously, if the user selects to receive only the MBMS business, the UE informing network existing non-MBMS business of breaking then; Execution in step 406; If the user selects to receive only non-MBMS business, then execution in step 409; If the user selects to receive two types business simultaneously, then execution in step 406.
Wherein, whether user decision transfers to and receives MBMS or the method that receives two types business simultaneously has two kinds:
First kind: the service selection information decision that the Non-Access Stratum of UE sets in advance according to the user: be lower than the MBMS business if the user is provided with this non-MBMS service priority, then selective reception MBMS business; If the UE ability allows, select to receive simultaneously; If this non-MBMS service priority is higher than the MBMS business, and the UE ability do not allow, and then selects not receive the MBMS business, certainly, if higher also can the selection of the ability of UE receives simultaneously.
Second kind: the Non-Access Stratum of UE by with user interactions, obtain user's decision and whether aim at and receive MBMS or receive two types business information simultaneously.
Step 406, the MBMS business of indicating in the UE preparation receiving control information.This process is identical with the process of prior art, repeats no more here.
Step 407, the professional reception condition information of MBMS that UE will comprise the ability that receives MBMS service priority table and UE reception MBMS business reports network side.
If the business that UE is receiving is transmitted in the PTP mode, then the ascending wireless resource of the dedicated link directly set up by this business of UE reports network side with the professional reception condition information of MBMS.
If the business that UE is receiving is also transmitted in the PTM mode, then the UE of different conditions has different processing, and is specific as follows:
For the UE that is in the Idle state, its elder generation sets up RRC with network side and is connected, and connects by the RRC that sets up, and the professional reception condition information of the MBMS of oneself is reported network side;
For the UE that is in the URA-PCH state, then change the CELL-FACH state over to, utilize up channel that the professional reception condition information of the MBMS of oneself is reported network side;
For the UE that is in the CELL-PCH state, then change the CELL-FACH state over to, utilize up channel that the professional reception condition information of the MBMS of oneself is reported network side;
For the UE that is in the CELL-FACH state, then directly utilize up channel that the professional reception condition information of the MBMS of oneself is reported network side.
That is to say, to being in the UE of Idle state, be to report the ascending wireless resource of the professional reception condition information of MBMS to report by setting up special use.
Step 408 continues to carry out the MBMS operation flow of indicating in the control information.Process ends.
Step 409, UE will comprise reception MBMS service priority table, ability with UE reception MBMS business, and the reception condition information whether the MBMS business that receiving of UE, the UE MBMS business, the user that prepare to receive refuses the non-MBMS business of the reception condition information of MBMS business such as one or more MBMS business and current reception reports network side.Report method and step 407 in this step are identical, repeat no more here.
In the present embodiment, UE can judge further that before reporting whether attach most importance to sending service and UE of the business of indicating in the control information correctly received this business information, if, then can not prepare the business of the high priority of indicating in the receiving control information, even reporting service reception condition information not.
In fact, UE can further judge whether comprise frequency layer convergence (FLC) information in the control information before reporting, if comprise, then carries out the frequency layer convergence operation earlier, reports the professional reception condition information of MBMS again, does not directly report if just do not comprise.
Step 410 continues the MBMS operation flow that is receiving.Process ends.
In the practical application,, just directly the professional reception condition information of self MBMS is reported network side, and do not consider the working condition of self, can simplify the handling process of UE like this as long as after UE can receive above-mentioned announcement information.
Because present embodiment can report network side with the professional reception condition information of MBMS in step 407 or step 409.Like this, network side just can be according to the reception MBMS service priority table of UE, with the ability that receives the MBMS business, judging UE current is to receive the MBMS business of transmitting, still prepare the business of indicating in the receiving control information, if the business of indicating in the preparation receiving control information then can be carried out restatement in this MBMS business and this UE be counted when counting, otherwise do not counted.
Such as: the receiving ability of UE can only receive a kind of MBMS business (common UE receiving ability all has only a kind), and the professional height of indicating in the priority ratio control information of the MBMS business of current reception, then judging UE current is to receive the MBMS business of transmitting, and do not prepare the business of indicating in the receiving control information, then this UE is not counted.If the receiving ability of UE can only receive a kind of MBMS business, and indicate in the priority ratio control information of the MBMS business of current reception professional low, then judging UE current is not receive the MBMS business of transmitting, and the business of indicating in the preparation receiving control information is then counted this UE.Like this, after the business of indicating in this control information is carried out the restatement number, can according to the user of statistics what, judge whether to surpass predetermined value, if do not surpass, then can issue this business, thereby reduce the power resource waste for adopting the PTP bearing mode.
In addition, if though UE has the ability that receives a plurality of business simultaneously, but because at present UE only wants to receive one of them or several business, UE also needs the business that will want to receive or/and the business that is receiving reports network side in the professional reception condition information of MBMS so.The business that network side will receive according to priority list, UE is judged the situation of the current reception of UE MBMS business or/and the business that is receiving.UE wants that the business that receives can also be temporarily to want the business that receives, can report with temporary transient reception service lists form.Network side can be added up UE according to the service lists of temporarily wanting to receive, and sends the MBMS business, and after the business in the service lists that UE temporarily wants to receive was all transmitted and finished, network side can be with this tabulation deletion.
Second preferred embodiment:
Referring to Fig. 5, Fig. 5 is the process chart of the inventive method second preferred embodiment.In the present embodiment, the professional reception condition information of the MBMS that UE will report comprises at least: receive the ability that MBMS service priority table and UE receive the MBMS business.This flow process may further comprise the steps:
Step 501, UE receives a kind of Counting announcement information of MBMS business by Common Control Channel.
Step 502, UE judges self whether to receive the professional or a kind of non-MBMS business of another or a plurality of MBMS, if then execution in step 503; Otherwise execution in step 504.
Step 503, UE judges whether self-ability can receive this MBMS business simultaneously, if can, execution in step 504; Otherwise execution in step 505.
Step 504, UE returns the Counting response that can receive this MBMS business to network side.Process ends.
Step 505, if comprise the MBMS business in the business that the user is receiving, whether the priority of then judging the business of indicating in the Counting announcement information is than the MBMS service priority height that is receiving, if then execution in step 507; Otherwise, execution in step 506.
If the business of the current reception of user does not comprise the MBMS business, be other non-MBMS business, the MBMS business of then pointing out the user whether to transfer to indicate in the reception notification information, if this MBMS business of user's selective reception, then execution in step 507; Otherwise continue to carry out non-MBMS business, execution in step 506.
Step 506, UE does not respond this Counting announcement information.Process ends.
Step 507 judges that whether attach most importance to sending service and UE of the business of indicating in the Counting announcement information correctly received this business information, if then execution in step 506; Otherwise execution in step 508.
Step 508 judges whether comprise frequency layer convergence (FLC) information in the Counting announcement information, if comprise, and execution in step 509 back execution in step 510 then; Otherwise direct execution in step 510.
Step 509 is carried out the frequency layer convergence operation.
The method of carrying out frequency layer convergence is same as the prior art, repeats no more here.
Step 510, UE reports network side with the professional reception condition information of MBMS with the Counting response message.
In the practical application, after as long as UE can receive above-mentioned announcement information, just directly the professional reception condition information of self MBMS is reported network side by ascending resource with the Counting response message, and do not consider the working condition of self, can simplify the handling process of UE like this.
In the present embodiment, if the right and wrong MBMS business of the current reception of UE, and the user selected to receive only the MBMS business of indicating in the Counting announcement information, then the UE informing network existing non-MBMS business of breaking also.
UE reports the method for the professional reception condition information of MBMS identical with one step 407 embodiment illustrated in fig. 4 or step 409 to network side in the present embodiment, also repeats no more here.
More than two flow processs be preferred embodiment, in the practical application to multiple processing being arranged, for example with the method that reports the professional reception condition information of MBMS: after UE reported the professional reception condition information of the MBMS of self, record once reported; When UE receives business control information, judge whether once to have reported the professional reception condition information of MBMS, if then do not report; Otherwise report.
If UE once reported the professional reception condition information of MBMS, can judge further that then whether the professional reception condition of this MBMS changes, if having, then reports; Otherwise no longer report.
UE can also report this information to network side immediately when knowing that the professional reception condition information of self MBMS changes, also can report according to the original opportunity that reports.
Can be described as the opportunity that UE reports among above-mentioned two embodiment by network side decision, also can be that the user determines in the practical application.For example, UE regularly reports network side with the professional reception condition information of self MBMS by ascending resource.
