Description
Technical field
The present invention relates to wireless communication field, refer to that especially a kind of notice is used to carry the method for MBMS (MultimediaBroadcasting Multicast Service multimedia broadcast-multicast service) business configuration parameter.
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), 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 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.
The structural model of MBMS system as shown in Figure 1.In order to support MBMS, increased mobile network functional entity---broadcast multicast service center BM-SC 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, UE (User Equipment, subscriber equipment), UTRAN (Universal Terrestrial Radio AccessNetwork, universal land radio access web), GERAN (GSM EDGE Radio Access NetworkGAM, the enhancing wireless access network), SGSN (Serving GPRS Support Node, Serving GPRS Support Node), GGSN functional entitys such as (Gateway GPRS Support Nodes) strengthens, and increased the relevant function of MBMS.
MBMS comprises multicast pattern and broadcast mode.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.
MBMS has two kinds of pattern: PTM (Point-to-Multipoint puts multiple spot) pattern and PTP (Point-to-Point, point-to-point) pattern when transmitting between UTRAN and UE.The PTM pattern sends identical data by MTCH (MBMS point-to-multipoint Traffic Channel, MBMS point-to-multipoint service channel) logic channel, and all add multicast service or can receive the interested UE of broadcasting service; Ptp mode sends data by DTCH (Dedicated Channel dedicated channel) logic channel, has only a corresponding UE to receive.
It is as follows that the user receives the idiographic flow of certain MBMS multicast service:
1, the user subscribes to (Subscription): set up the contact between user and the service supplier;
2, professional announce (Service announcement): the relevant information of notifying user MBMS;
3, add (joining): the user notification network prepares to receive MBMS;
4, session begins (Session Start): BM-SC is ready for sending data;
5, MBMS Notification:RNC notifies user MBMS muticast data transmission;
6, data transmission procedure;
7, conversation end (Session Stop): BM-SC has not been ready for sending data, and bearing resource can discharge.
8, leave (leaving): the user no longer has been the member of MBMS multicast group.
In MBMS multicast service flow process, the user add and session to begin two steps be separate, that is to say a user may be before session begins also may the session after session begins carry out in multicast service of adding.
MCCH (the MBMS point is to the multiple spot control channel) is the channel of MBMS transmission control information.Comprising content have at least: MBMS SERVICE INFORMATION (MBMS information on services); MBMS RADIO BEARER INFORMATION (MBMS radio bearer information); MBMSNEIGHBORING CELL INFORMATION (MBMS neighboring BS information) etc.
The user receives and finishes in this time period to Data Receiving before the MBMS data, when RNC notifies the user to receive certain MBMS, need be with configuration parameter, and configuration parameter is notified the user when changing.
The step of notifying the user to carry the MBMS parameter in the agreement is as follows at present:
1, after UTRAN receives Session Start indication from certain MBMS of CN, can carry out Counting (user number counting) process as required;
If the PTM mode is used in 2 UTRAN decision, UTRAN can dispose the configuration parameter relevant with this business so, and the corresponding information (MBMS SERVICE INFORMATION and MBMS RADIO BEARER INFORMATION) on the renewal MCCH, comprise the PTM information of MBMS ID (MBMSIdentity, MBMS sign) and this MBMS etc.;
3, at DRX (Discontinuous Reception, discontinuous reception) wakeup state, UE under the idle condition and CELL_FACH, CELL_PCH and URA_PCH read MBMS NI (MBMS Notification, the MBMS notice), if detect MBMS NI, then read MCCH so that obtain MBMS information and configuration parameter information in the predefined time;
4, after the user receives MBMS information and configuration parameter information, can use MCCH to go up this MBMS of configuration parameter message pick-up of indication.
If the PTP mode is used in 5 UTRAN decision, UTRAN can use the user of traditional paging mechanism notice CELL-PCH state to carry out cell update so, or notifying the user who is in the Idle state to set up RRC connects, and further UTRAN sets up PTP RB by RRC processes such as for example RB setup procedure;
6, UE sets up PTP RB carrying by the RRC process of UTRAN selection;
7, UTRAN upgrades new the adding or the user-dependent MBMS information that has just entered the sub-district of MBMS SERVICE INFORMATION notice on the MCCH.
Prior art problems is:
For each MBMS that has determined bearing mode, all need to notify the user configuration parameter information that should business by MCCH.Because amount of information is general bigger, so it is very serious for the resource occupation of the MCCH of finite capacity.If according to prior protocols, even several MBMS uses a kind of configuration parameter combination, so also must broadcast repeatedly, waste very much MCCH resource and interface-free resources.
MCCH is the unique control information channels of all MBMS, therefore needs the control information of carrying many.If need on the MCCH can to reduce the information of this class large information capacity of configuration parameter of transmitting, so also will be very beneficial for reducing the Data Receiving mistake that the transmission configuration parameter error causes, can also reduce air interface information transmitted amount simultaneously.
In fact, though MBMS is very abundant, its QoS (Quality of Service, service quality) type but is less relatively.From the agreement of present R6, has only the business of two types of streaming and background from big aspect.The transmission channel FACH that when actual transmissions MBMS, uses (Forward Access Channel, forward access channel) and physical channel SCCPCH (SecondaryCommon Control Physical Channel, inferior Common Control Physical Channel) number is also limited, we can say that therefore actual available PTM configuration parameter combination is fewer with respect to abundant MBMS.
Therefore, can be combined into line identifier or classification by the configuration parameter that these are limited fully, on broadcast channel, carry out respective broadcast, effectively reduce the amount of information of MCCH channel with the MCCH channel.
