Description
Technical field
The present invention relates to the method for subscriber equipment (UE) receiving control information in the multimedia broadcast/group broadcast service (MBMS), particularly in the MBMS business, UE receives the method for Radio Resource control (RRC) message on the control channel.
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 MBMS business has two kinds of patterns 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.
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.The service dispatching informations such as time started, duration and concluding time of the MBMS that UTRAN is about to begin by service dispatching channel (MSCH) notice UE in this process; After UE receives this notice, when beginning, this business receives the MBMS business according to this notice.Like this, UE can only obtain the service dispatching informations such as time started of the MBMS business that is about to begin, can not obtain the service dispatching informations such as transmitting sequence of network side for multiple MBMS business.
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 UTRAN phase related control information that all are professional transmits on the RRC of MCCH channel bearing message.In the MBMS business, except by going up transmission in Broadcast Control Channel (BCCH) about the limited control information such as the configuration information of access information, the professional control of MBMS channels such as (MCCH), most of RRC message are all in the MCCH channel.
MCCH information is periodically to send, and UTRAN can repeat to send MCCH information to improve stability.The MCCH message scheduling is consistent for all business.
Referring to Fig. 4, Fig. 4 is a MCCH message scheduling cycle schematic diagram.Whole M CCH information transmitted periodically based on " repetition period "." modification cycle " is defined as the integral multiple of " repetition period ".MBMS AccessInformation transmitted periodically based on " access information cycle "." repetition period " is again the integral multiple in " access information cycle " simultaneously.
The RRC message of the last carrying of MCCH mainly comprises: MBMS access information (MBMS Access Information, MAI), MBMS revises business information (MBMS Modified Services Information, MSI), the RB configuration information (Changed RB Configuration Information) that changes, the non-modification business information of MBMS (MBMS Unmodified Services Information), RB configuration information of non-variation (Unchanged RB Configuration Information) or the like.
Wherein, information such as MBMS Modified Services Information are key messages, and key message is immovable in a modification cycle, and access informations such as MBMS Access Information then are to change at any time.The Modified business information is the business information that changes in this modification cycle, and same Unmodified business information is the business information that does not have variation in this modification cycle.
The user is in receiving the MBMS process, receive different RRC message according to different condition needs, such as needing to receive the business information that has changed sometimes, there is not the business information that changes and need sometimes to receive, therefore in order to reduce the time that the user receives the MBMS business control information, need the user can know the position at each RRC message place.
Because the professional number of MBMS is numerous, therefore the professional number that may exist in a RRC message is many.At present, the process of UE reception RRC message mainly may further comprise the steps:
1, UTRAN arranges all RRC message in a certain order at MCCH, in addition, arranges the order of each MBMS business arbitrarily on each RRC message; Issue RRC message according to arranged order to UE.
2, UE receives all RRC message, or receiving oneself at least need receive RRC message all message before, carries out demodulation one by one, up to obtaining needed control information.
By said process as seen, because the RRC message on the MCCH is unique channel of MBMS transmission business control information, so the control information that it need carry is a lot, and the loaded service type also is a lot.Only need the wherein a kind of or several business that provide in the sub-district are provided for UE, in order to receive the control information of limited business, UE must receive all control channel information or the control information that all are professional, and doing like this for UE is to have increased power consumption.
Specifically, when UE need receive certain RRC message, because UE do not know message from which place, so it had to one by one that message receives, contrast.For a plurality of MBMS business on the RRC message, the user also must get off all message pick-ups wherein so, contrasts the sign of each business again, and whether business information be own needed, till the information that receives own needs.
In a word, just determined the transmission sequence of each RRC message on the MCCH channel in the prior art, but do not consider how UE can locate each RRC message exactly, and the position of each MBMS business in the RRC message, cause UE must receive a large amount of unwanted control informations, increase power consumption, wasted system resource.
