Description
Technical field
The present invention relates to multi-medium broadcast/group broadcast service (MBMS) technology, refer to a kind of method and device that sends multimedia broadcasting multicast service especially.
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 communications network, sub-district multicast service or broadcasting service (CBS, Cell Broadcast Service) allow low bit rate data to share broadcast channel to all users' transmissions by the sub-district, and this kind business belongs to information series business.
Now, people no longer are satisfied with phone and messaging service to the demand of mobile communication, and along with the fast development of internet (Internet), a large amount of mobile multi-media services emerge.The some of them mobile multi-media service requires a plurality of users can receive identical data, for example video request program, television broadcasting, video conference, online education, interactive game etc. simultaneously.These mobile multi-media services are compared with general data service, have characteristics such as data volume is big, longer duration, delay sensitive.Present Internet protocol (IP) multicast and broadcast technology only are applicable to wired IP communication network, be not suitable for mobile communications network, because mobile communications network has particular network structure, functional entity and wave point, these are all different with the wire communication IP network.
In order to effectively utilize the mobile communications network resource, 3G (Third Generation) Moblie global standards tissue (3GPP) has proposed the MBMS of mobile communications network, thereby in mobile communications 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 that 3GPP proposes 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.
Fig. 1 is for supporting the wireless network architecture schematic diagram of broadcasting/packet service, as shown in Figure 1, among the existing 3GPP, support that the wireless network entity of broadcasting/packet service is a broadcasting/packet service server (BM-SC) 101, BM-SC101 is by Gmb interface or Gi interface and critical point GPRS Support Node (GGSN, GatewayGPRS Support Node) 102 link to each other, and a BM-SC101 can link to each other with a plurality of GGSN102; GGSN102 links to each other by Gn/Gp interface and Serving GPRS Support Node (SGSN, Serving GPRSSupport Node) 103, and a GGSN 102 can link to each other with a plurality of SGSN 103; SGSN 103 can link to each other with universal mobile telecommunications system (UMTS) land radio access web (UTRAN) 104 by the Iu interface, UTRAN 104 links to each other with UE 106 by the Uu interface then, SGSN 103 also can strengthen wireless access network (GERAN) 105 by Iu/Gb interface and global system for mobile communications and link to each other, and GERAN 105 links to each other with UE 107 by Um Interface then.Wherein, GGSN and SGSN belong to the node in the core net in the wireless network (CN).
The network configuration that provides from Fig. 1 as can be seen, in order to support the MBMS business, in 3-G (Generation Three mobile communication system), increased mobile network functional entity--broadcast multicast service center, be BM-SC, described BM-SC is content provider's a inlet, be used for authorizing and initiating the MBMS business, and plan transmits the MBMS content to schedule at mobile network.In addition, on functional entitys such as UE, UTRAN, GERAN, SGSN, GGSN, increased the function relevant with MBMS.
MBMS comprises multicast pattern and broadcast mode, and wherein 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 pattern and broadcast mode exist on business demand, cause also difference of operation flow separately, as shown in Figures 2 and 3, Fig. 2 is the operation flow schematic diagram of MSMS multicast pattern, Fig. 3 is the operation flow schematic diagram of MSMS broadcast mode.
As shown in Figure 2, the processing procedure that relates to of MBMS multicast service comprises: signatory (Subscription), service declaration (Service announcement) also claim service statement, user to add that (Joining), session begin (Session Start), MBMS notice (MBMS notification), data transmit (Data transfer), conversation end (Session Stop) and user and withdraw from (Leaving).Wherein, signatory process is used for setting up the relation between user and the service supplier, allows the user subscribe to required MBMS service in advance; Service declaration process is used for promptly notifying user MBMS the relevant information of business by the current service that can provide of BM-SC declaration; User's adition process is a MBMS activation of service process, UE is in adition process, informing network self is ready to become the member of current multicast group, receives the data of corresponding MBMS business, and this adition process can be created the MBMS UE context of record UE information in the UE of network and adding multicast group; Session begins in the process, and BM-SC is ready to transfer of data, and informing network is set up the bearing resource of corresponding core net and Access Network; The MBMS notification procedure is used for being about to begin by RNC notice UE MBMS multicast conversation; In data transfer procedure, BM-SC transfers data to UE by the bearing resource that session begins to set up in the process, the MBMS business has two kinds of patterns when transmitting between UTRAN and UE: point-to-multipoint (PTM) pattern and point-to-point (PTP) pattern, the PTM pattern sends identical data by MBMS point-to-multipoint service channel (MTCH), all add multicast service or can receive the interested UE of broadcasting service, ptp mode sends data by the DTCH logic channel, has only a corresponding UE to receive; The conversation end process is used for the bearing resource that the session process that begins is set up is discharged; The user withdraws from 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.
As shown in Figure 3, processing procedure that the MBMS broadcasting service relates to and MBMS multicast service are similar, just before session begins, do not need to carry out signatory process and user's adition process, and, after conversation end, do not need to carry out the user and withdraw from process.
In MBMS PTM transmission mode, relevant controlled in wireless information comprises business information, access information, radio bearer information, frequency layer convergence (FLC) information etc., is all sent to multiple spot control channel (MCCH) by logic channel such as MBMS point by Radio Resource control (RRC) layer.Usually, MCCH information is based on that the mode of fixed schedule transmits, and in order to improve reliability and stability, UTRAN can repeat to send MCCH information.Fig. 4 is a MCCH transmission of Information scheduling graph, and as shown in Figure 4, the cycle that repeats to send MCCH information is repetition period (RP), and complete MCCH information can periodically be sent according to the repetition period.The modification cycle, (MP) then was defined as the repetition period of integral multiple, all will make amendment to MCCH information in each modification cycle.The access information of MBMS can periodically be sent according to the access information cycle, and the access information cycle is that the integer of repetition period is cut apart.The MCCH scheduling is consistent for all business.
MCCH information is divided into key message and non-critical information again, wherein, key message is made up of MBMS information of adjacent cells (MBMS neighboring cell information), MBMS business information (MBMS serviceinformation), MBMS radio bearer information (MBMS radio bearer information), periodically transmit with repetition period and modification cycle, key message can not change in each modification cycle; Non-critical information is meant MBMS access information (MBMS access information), transmits at access period, and access information can be revised at any time, and the square that black is filled among Fig. 4 is represented change information.
At present, the MBMS system is an important attribute of 3GPP Release6 version, in other words is exactly, and the MBMS technology is attached to existing 3G system, the MBMS business is carried by existing transmission channel and physical channel, uses existing frequency and bandwidth etc.Specifically, referring to shown in Figure 5, providing of MBMS business can be divided into three phases (phase):
Phase I is the period before session begins, and in this stage, network does not provide any MBMS business, and the user may constantly attempt reading the MBMS announcement information, and in this stage, the user can add any business at any time.
To be UTRAN receive session (Session Start) sets up radio bearer (RB) to UTRAN for this business till from core net second stage.It is professional and carry out counting (counting) process to MBMS is professional to notify the user to receive MBMS at this stage UTRAN, so that the decision bearer types.UE can respond counting in this stage, receives the MCCH control channel to obtain the phase related control information.
Three phases is the of paramount importance stage of MBMS, and in this stage, the user begins to receive the MBMS business, obtains session until UTRAN from core net and stops (Session Stop).
From the angle of UTRAN, the professional process of transmitting of MBMS may further comprise the steps as shown in Figure 6:
Step 601.UTRAN obtains session (Session Start) indication of certain MBMS service conversation from CN;
Step 602.UTRAN determines whether this MBMS business is carried out the counting flow process as required, to determine its bearing mode;
Step 603. is respectively on the MCCH channel and on the MBMS informing indication channel (MICH), sends the notice indication that phase related control information and MBMS business change to UE;
Step 604. uses the bearing mode of counting process decision that MBMS is provided business on MTCH;
After step 605. received that the session of CN transmission stops (Session Stop) indication, UTRAN discharged the professional corresponding RB information of this MBMS.
In the professional process of transmitting of existing MBMS, UTRAN does not do selection to the transmission carrier frequency of MBMS business, and UTRAN focuses on certain frequency with receiving certain professional user when making user's scheduling process, this frequency is exactly the transmission carrier frequency of MBMS business, is current WCDMA carrier frequency.
Because the type of service that the MBMS system relates to is quite a lot of, from background service such as software download, to real time business such as video tour etc., along with increasing gradually of service provider (SP), the professional number of MBMS can constantly increase.At present, sending MBMS when professional, use be that the resource of current WCDMA has promptly been used existing transmission channel and physical channel, the current WCDMA carrier frequency that this paper will send the MBMS business at present is called non-MBMS carrier frequency.The existing this mode of utilizing non-MBMS carrier frequency to send the MBMS business makes MBMS take a large amount of existing Radio Resources, like this, has influenced the transmission of existing other business on the one hand greatly; On the other hand, also greatly limited the type of service that MBMS can provide simultaneously.
