Description
Technical field
The present invention relates to the broadcast/multicast service technology, particularly realize the transmission method of a kind of broadcasting/packet service control information in the broadcasting/packet service based on single carrier.
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 broadcasting/packet service server (BM-SC), BM-SC is by Gmb interface or Gi interface and critical point GPRS Support Node (GGSN, Gateway GPRSSupport Node) link to each other, 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 UE by the Uu interface then, SGSN also can strengthen wireless access network (GERAN) by Iu/Gb interface and global system for mobile communications and link to each other, and GERAN links to each other with UE 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), user add that (Joining), session begin (Session Start), MBMS notice (MBMS notification), data transmit (Data transfer), conversation end (SessionStop) 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., all pass through logic channel, send to multiple spot control channel (MCCH) as the 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).
In said process, UTRAN sends the MBMS control information by MBMS control channel MCCH to UE.Because present R6MBMS uses same carrier wave frequency range (abbreviation carrier frequency) with the WCDMA system, therefore, the transmission of control information is to be undertaken by the carrier wave frequency range that has 3G network now on the MCCH channel, and promptly there is not the problem of selecting carrier wave frequency range to receive the MBMS control information in UE.
The description of concrete MBMS control information, and transmission and UE method of reseptance are as follows:
No matter UE is in which kind of state (idle, URA_PCH, CELL_PCH, CELL_FACH andCELL_DCH), so long as UE has added the MBMS business, so all needs to receive with its professional relevant MCCH and goes up the control information of carrying.
As mentioned above, be divided into key message and non-critical information in the control information.Wherein access information is a non-critical information, according to own distinctive access information periodic transfer; Other crucial MCCH control information is a periodic transfer, and the cycle comprises modification cycle and repetition period.
If the professional PTM of use bearing mode transmits, the user also needs to receive the MSCH channel, the schedule information of the MBMS business that the transmission on it is specifically transmitted on the SCCPCH physical channel.
The control information of UTRAN MBMS transmission is with in sequence special, catches the MBMS control information that MCCH goes up carrying to guarantee the user with the minimum time, and does not receive unwanted control information.
The MBMS control information that the MCCH that UE need receive upward carries comprises following information as shown in Figure 6:
1, MBMS change information (MBMS MODIFIED INFORMATION);
2, the non-change information of MBMS (MBMS UNMODIFIED INFORMATION);
3, MBMS access information (MBMS ACCESS INFORMATION);
4, MBSM general information (MBMS GENERAL INFORMATION);
5, the public P-T-M radio bearer information of MBMS (MBMS COMMON P-T-M RBINFORMATION);
6, MBMS current area P-T-M radio bearer information (MBMS CURRENT CELLP-T-M RB INFORMATION);
7, MBMS neighbor cell P-T-M radio bearer information (MBMS NEIGHBOURINGCELL P-T-M RB INFORMATION);
That is to say that the control information that UTRAN is relevant with MBMS sends to relevant UE, UE is then according to the service conditions that self adds, receiving unit or all MBMS control informations selectively.
Because the type of service that relates to of MBMS system 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), professional number can constantly increase.And MBMS is the enhancing of existing WCDMA system at present, and it has used the resource of existing WCDMA, has promptly used existing transmission channel and physical channel.Its consequence is that MBMS has taken a large amount of existing Radio Resources.Influence just is present in two aspects like this: the one, and existing business can be subjected to great influence; But the type of service that MBMS can provide simultaneously has been subjected to greatly restriction.
At present, for distributing a descending carrier, MBMS is very important separately.Can liberate the resource of existing system on the one hand, be convenient to the utilization of resources of system; From the angle of operator, the interests that can obtain are much larger than the cost for setting up the separate carrier frequency range to pay on the other hand.
Therefore introduce new carrier wave frequency range carrying MBMS business, and with the co-ordination of original MBMS carrier wave will be that a solution is eated dishes without rice or wine to the good method of MBMS volume of business restriction.But the transmission and the UE receiving course that are based on the MBMS business control information of single carrier frequency section MBMS system are then gone back the clear and definite implementation process of neither one.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The transmission method of this broadcasting/packet service control information of the present invention, distributing for broadcast/group broadcast in the system of special carrier frequency range, network side sends the broadcast/group broadcast control information to UE on broadcast/group broadcast special carrier frequency range and/or non-broadcast/group broadcast special carrier frequency range; Prepare to receive the UE of broadcasting/packet service, the situation according to the broadcast/group broadcast control information is transmitted on which carrier wave frequency range receives the broadcast/group broadcast control information in broadcast/group broadcast special carrier frequency range and/or on non-broadcast/group broadcast special carrier frequency range.
Usually distributing in the system of special carrier frequency range for broadcasting/packet service, UE is known the information of broadcast/group broadcast special carrier frequency range earlier.In the present invention, UE recorded announce/multicast special carrier band information in advance; Can also be on non-broadcast/group broadcast special carrier frequency range by network side, send broadcast/group broadcast special carrier band information to UE, such as: network side can be on broadcast channel or control channel, according to the transmission cycle of broadcast channel or control channel, regularly send broadcast/group broadcast special carrier band information to UE.Then, UE can when needed, receive the MBMS control information according to this broadcast/group broadcast special carrier band information record or that receive on broadcast/group broadcast special carrier frequency range.
Among the present invention, UE can have multiple mode to know the situation that control information is transmitted on which carrier wave frequency range.For example following three kinds of modes:
One, UE is known the situation that control information is transmitted according to the situation that receives control channel on which carrier wave frequency range.Specifically, when if UE is in non-broadcast/group broadcast special carrier frequency range, can on the control channel of non-broadcast/group broadcast special carrier frequency range, receive the broadcasting/packet service control information earlier, if do not receive, then to the control channel of broadcast/group broadcast special carrier frequency range, receive the broadcasting/packet service control information again.When if UE is in broadcast/group broadcast special carrier frequency range, can on the control channel of broadcast/group broadcast special carrier frequency range, receive the broadcasting/packet service control information earlier, if do not receive, then to the control channel of non-broadcast/group broadcast special carrier frequency range, receive the broadcasting/packet service control information again.Under this mode, UE relatively blindly need repeatedly switch the system resource that may waste UE sometimes back and forth between non-broadcast/group broadcast special carrier frequency range and broadcast/group broadcast special carrier frequency range.
Two, network side and UE are set in advance in and send the broadcast/group broadcast control information on broadcast/group broadcast special carrier frequency range and/or the non-broadcast/group broadcast special carrier frequency range, and UE writes down this setting; UE is known the situation that control information is transmitted according to the setting of record on which carrier wave frequency range, receive the broadcasting/packet service control information to the carrier wave frequency range of correspondence.Under this mode, the situation that UE receives is more fixing, issues the broadcasting/packet service control information if network side changes frequency, needs UE to change simultaneously, realizes underaction.
Three, network side is sent in the indication that sends the broadcast/group broadcast control information on which carrier wave frequency range to UE on non-broadcast/group broadcast special carrier frequency range and/or broadcast/group broadcast special carrier frequency range; UE is known the situation that control information is transmitted according to this indication on which carrier wave frequency range, receive the broadcasting/packet service control information to the carrier wave frequency range of correspondence.Under this mode, network side only needs to send an indication to UE, if changing frequency, network side issues the broadcasting/packet service control information, UE is as long as change according to indication, therefore realize flexibly, do not need repeatedly between non-broadcast/group broadcast special carrier frequency range and broadcast/group broadcast special carrier frequency range, to switch back and forth, reduce the system resource waste of UE.In the practical application, this mode is adopted in suggestion.
The present invention both can be applied in the multimedia broadcast/group broadcast service (MBMS) and also can be applied in the non-multimedia broadcasting/packet service, and processing mode is identical.
Below with regard to above-mentioned the third mode, the present invention will be described in detail to lift four preferred embodiments in the MBMS service application.
First preferred embodiment:
In the present embodiment, network side is controlled at all MBMS on the non-MBMS special carrier frequency range and issues.Specifically, network side issues MBMS dedicated frequency information, sends the indication of MBMS control information and all MBMS control informations on which carrier wave frequency range on non-MBMS special carrier frequency range.In the present embodiment, network indication UE MBMS control information also can be carried out on the MBMS carrier wave frequency range in transmission on which carrier wave frequency range simultaneously.
In the present embodiment, network side is on the broadcast channel or control channel of non-MBMS special carrier frequency range, according to the transmission cycle of broadcast channel or control channel, regularly send MBMS special carrier band information and the indication of transmission MBMS control information on which carrier wave frequency range to UE.After UE enters into UTRAN in start or reselection procedure sub-district or from other wireless access technology (RAT), receive above-mentioned two kinds of information after, the information of recorder.
In the present embodiment, UE receives the process of MBMS control information referring to Fig. 7, and Fig. 7 receives the schematic flow sheet of MBMS control information for UE in the present invention's first preferred embodiment.This flow process may further comprise the steps:
Three following embodiment also are example with the multicast.
UE at first obtains the professional professional control messages (MSI and USI) that changes and do not change of MBMS after entering into UTRAN in start or reselection procedure sub-district or from other RAT.
