Description

信息传输方法技术领域 TECHNICAL FIELD The information transmission

[0001] 本发明涉及信息传输技术,尤其涉及多媒体广播/组播业务(MBMS,Multimedia Broadcast/Multicast Service)中传输MBMS 控制信息的方法。 [0001] The present invention relates to an information transmission technology, and particularly relates to a method for multimedia broadcast / multicast service (MBMS, Multimedia Broadcast / Multicast Service) in transmitting the MBMS control information. 背景技术 Background technique

[0002] 在移动通讯网络中,组播和广播是一种从一个数据源向多个目标传送数据的技术。 [0002] In a mobile communication network, multicast and broadcast are techniques for transferring data from a data source to multiple targets. 在传统移动通讯网络中,小区组播业务或广播业务(CBS,Cell BroadcastService)允许低比特率数据通过小区共享广播信道向所有用户发送,此种业务属于消息类业务。 In the conventional mobile communication network, multicast service or cell broadcast service (CBS, Cell BroadcastService) allows low bit rate data through a cell shared broadcast channel to all users, messaging services such service belongs.

[0003] 现在,人们对移动通信的需求已不再满足于电话和消息业务,随着因特网(Internet)的迅猛发展,大量移动多媒体业务涌现出来。 [0003] Now, the demand for mobile communications are no longer satisfied with telephone and message service, along with the Internet (Internet) the rapid development of a large number of mobile multimedia services emerge. 其中一些移动多媒体业务要求多个用户能同时接收相同数据,例如视频点播、电视广播、视频会议、网上教育、互动游戏等。 Some mobile multimedia services require that multiple users can simultaneously receive the same data, such as video on demand, television broadcast, video conferencing, online education, and interactive games. 这些移动多媒体业务与一般的数据业务相比,具有数据量大、持续时间长、时延敏感等特点。 Compared with the general data traffic of these mobile multimedia services, having a large amount of data, long time duration, delay sensitive and so on. 目前的网际协议(IP)组播和广播技术只适用于有线IP通讯网络,不适用于移动通讯网络,因为移动通讯网络具有特定的网络结构、功能实体和无线接口,这些都与有线通讯IP 网络不同。 The current Internet Protocol (IP) multicast and broadcast IP technology is only applicable to a wired communication network, not to a mobile communication network, since the mobile communication network has a specific network structure, function entities and wireless interfaces, which are wire communication with the IP network different.

[0004] 为了有效地利用移动通讯网络资源,第三代移动通讯全球标准化组织(3GPP)提出了移动通讯网络的MBMS,从而在移动通讯网络中提供一个数据源向多个用户发送数据的点到多点业务,实现网络资源共享,提高网络资源的利用率,尤其是空口接口资源。 [0004] To effectively utilize mobile communication network resources, the third generation mobile communication global standardization organization (3GPP) proposes an MBMS mobile communication network, so as to provide a point source sends data to a plurality of user data to the mobile communications network multipoint service, to share network resources, improve the utilization of network resources, especially air interface resources. 3GPP提出的MBMS不仅能实现纯文本低速率的消息类组播和广播,而且还能实现高速多媒体业务的组播和广播,这无疑顺应了未来移动数据发展的趋势。 MBMS 3GPP proposed not only to achieve a low rate of plain text messages multicast and broadcast, but also to achieve high-speed multicast and broadcast multimedia services, which undoubtedly conforms to the development trend of mobile data in the future.

[0005] 图1为MBMS的体系结构图,如图1所示,为了支持MBMS业务,在移动通讯网络中新增了移动网功能实体:广播组播业务中心(BM-SC),用于授权和在移动通讯网络中发起MBMS承载业务,并按照预定时间计划传送MBMS内容,是内容提供者的入口。 [0005] FIG. 1 is a configuration diagram of an MBMS architecture, shown in Figure 1, in order to support the MBMS service, a new mobile network functional entity in the mobile communication network: a broadcast multicast service center (BM-SC), for authorization and initiating in the mobile communication network in MBMS bearer service, and transmitting the MBMS content according to a predetermined program time is the entrance of content providers. 此外,为了支持MBMS业务,用户终端(UE)、通用移动电信系统(UMTS)陆地无线接入网(UTRAN)、全球移动通信系统/全球演变增强数据率(GSM/EDGE)无线接入网(GERAN)、服务通用分组无线电业务(GPRQ的支持节点(SGSN)、网关GPRS支持节点(GGSN)等功能实体进行增强,增加了MBMS相关的功能。 In addition, in order to support MBMS service, the user terminal (UE), Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN), Global System for Mobile Communications / Enhanced Data Rates for Global Evolution (GSM / EDGE) Radio Access Network (GERAN ), serving General packet radio service (GPRQ support node (SGSN), gateway GPRS support node (GGSN) and other functional entities enhanced with MBMS-related functions.

[0006] MBMS包括组播模式和广播模式。 [0006] MBMS includes multicast mode and broadcast mode. 组播模式需要用户签约加入相应组播组,进行业务激活,并产生相应的计费信息;而广播模式则不需用户签约加入既可进行业务激活。 Multicast mode requires the user to sign up to the appropriate multicast group, a service activation, and generates corresponding billing information; and the broadcast mode can be added without user subscription service activation. 由于组播和广播模式在业务需求上存在不同,因此导致其业务流程也不同。 Since the broadcast or multicast mode there is a difference on service requirements, thus leading to different business processes.

[0007] 图2为MBMS组播模式业务流程图,其流程依次包括:签约、业务声明、用户加入、会话开始、MBMS通知、数据传送、会话结束和用户退出。 [0007] FIG 2 is a flowchart of MBMS multicast mode service, which flow in turn comprising: signing a statement service, a user is added, session start, MBMS notification, data transfer, and end users to exit the session.

[0008] 图3为MBMS广播模式业务流程图,其流程依次包括:业务声明、会话开始、MBMS通知、数据传送、会话结束。 [0008] FIG. 3 is a flowchart of MBMS broadcast service mode, the process comprising successively: business statement, session start, MBMS notification, data transfer, end the session.

[0009] 上述在组播模式业务和广播模式业务的数据传送阶段,MBMS业务在UTRAN和UE 间传输信息的方式有两种模式:点到多点(PTM,Point toMultipoint)模式和点到点(PTP,Point to Point)模式。 [0009] In the above-described data transfer phase multicast mode service and the broadcast service mode, MBMS service between the UTRAN and the UE transmitting information in a manner two modes: point to multipoint (PTM, Point toMultipoint) mode and a point ( PTP, Point to Point) mode. PTM模式通过MBMS点到多点业务信道(MTCH)发送相同的数据,所有加入组播业务或对广播业务感兴趣的UE都可以接收;PTP模式通过专用业务信道(DTCH) 发送数据,只有相应的一个UE可以接收到。 PTM transmission mode by multipoint MBMS Traffic Channel (MTCH) the same data, all added to the multicast service or are interested in the broadcast service can receive the UE; the PTP mode, data is transmitted through a dedicated traffic channel (the DTCH), only the corresponding a UE can receive.

[0010] 在MBMS PTM传输模式中,相关的无线控制信息,包括业务信息、接入信息、无线承载信息、FLC信息等,都由无线资源控制(RRC,Radio ResourceControl)层通过逻辑信道, 即MBMS 点到多,点控制信道(MCCH,MBMSpoint-to-multipoint Control Channel)发送。 [0010] In the PTM MBMS transmission mode, relevant radio control information, including service information, access information, radio bearer information, the FLC information and the like, by radio resource control (RRC, Radio ResourceControl) layer through a logical channel, i.e., MBMS point to multi-point control channel (MCCH, MBMSpoint-to-multipoint Control Channel) transmission. 图4为MCCH的协议栈结构图,如图4所示,MCCH的协议单元由上至下依次为:RRC层、无线链路控制层(RLC)、介质访问控制层(MAC)、物理层(PHY)。 FIG 4 is a configuration diagram of a protocol stack of the MCCH shown in Figure 4, the MCCH protocol units is from top to bottom: RRC layer, a radio link control layer (the RLC), medium access control layer (the MAC), physical layer ( PHY).

[0011] 图5为MAC层的逻辑通道与物理层的FACH通道的映射关系图,如图5所示,在现有的系统中,MCCH信息,即MBMS的控制信息都被映射到前向接入信道(FACH,Forward Access Channel)传输信道上发送。 [0011] FIG. 5 is a graph mapping a logical channel FACH channel physical layer of the MAC layer, as shown in FIG. 5, in the conventional system, the MCCH information, i.e., MBMS control information are mapped to a forward access the channel (FACH, Forward Access channel) transport channel transmission.

[0012] 图6为MCCH信息的传输调度图,如图6所示,MCCH信息是基于固定调度的方式来传送的。 [0012] FIG. 6 is a transmission scheduling of the MCCH information, as shown in FIG 6, the MCCH information is scheduled based on a fixed manner to the transmission. 并且为了提高可靠性,UTRAN需重复发送MCCH信息。 And in order to improve the reliability, UTRAN transmits the MCCH information to be repeated. 重复发送MCCH信息的周期为“重复周期”,完整的MCCH信息会根据“重复周期”被周期性的发送。 MCCH information is repeatedly transmitted a cycle of "repetition period" complete MCCH information will be transmitted periodically in accordance with the "repetition period." “修改周期”则被定义为整数倍的重复周期,在每一个修改周期内都要对MCCH信息进行修改。 "Modification period" is defined as an integer multiple of the repetition period of the MCCH information to be modified in every modification period. MBMS的接入信息可以根据“接入信息周期”被周期性的发送,并且“接入信息周期”是重复周期的整数分割。 MBMS access information may be an "access info period" is periodically transmitted in accordance, and an "access info period" repetition period is an integer division.

[0013] MCCH信息又被分成准则信息和非准则信息。 [0013] MCCH information is further divided into non guideline information and criteria information. 其中,准则信息由MBMS邻小区信息、 MBMS业务信息、MBMS无线承载信息组成,且为需周期性重复发送的信息,在每个重复周期中所发送的内容不变,只能在修改周期中,MCCH信息第一次发送时才可以被修改;非准则信息是指MBMS接入信息,且为不需周期性重复发送的信息,可在任何时间修改。 Wherein, by the MBMS neighbor cell information criterion information, MBMS service information, MBMS radio bearer information composition, and periodically repeating the information transmission need, the content transmitted in each repeating the same cycle, only in the modification period, when the first transmission MCCH information may be modified; refers to a non-MBMS access information criterion information, and the information need not repeatedly transmitted periodically, may be modified at any time.

[0014] 现有技术方案中,RLC采用非确认模式(UM)来传送MCCH信息,并且使用同一个RLC UM实体将准则信息和非准则信息通过一个MCCH逻辑信道来传送。 [0014] In prior art solutions, using the RLC unacknowledged mode (UM) to transmit the MCCH information, and use the same RLC UM entity and non guideline information criterion information is transmitted through a logical channel MCCH. 参见图7,为MBMS控制信息的传输方式图。 Referring to FIG. 7 for transmission of MBMS control information in FIG. 现有技术中,MBMS控制信息的传输方法主要包括发送方(Sender)的RLC UM实体的发送过程,和接收方(Receiver)RLC UM实体的接收过程。 In the prior art, the MBMS control information transmission method includes receiving during transmission process sender (Sender) of the RLC UM entity, and a receiver (Receiver) RLC UM entity. 在每个传输时间间隔内可以发送一个或几个PDU,MAC决定每个传输时间间隔内PDU的大小和个数。 One or several PDU may be transmitted in each transmission time interval, MAC determines each transmission time interval within the PDU size and number.

[0015] 目前,非确认模式数据协议数据单元(UMD PDU)的发送过程是:发送方RLC UM实体接收到高层的非确认模式数据传输请求后,发送方调度从高层接收到的RLC业务数据单元(SDU)来发送;如果有一个或多个RLC SDU已经被调度来发送,则RLC UM实体先通知低层从高层接收包括SDU数目和大小的数据;然后RLC UM实体根据低层指示的PDU大小对SDU分段,如果可能也进行级联;之后,设置序列号域为VT (US),为每个在UMD PDU中结束的SDU设置长度指示域;最后,提交所请求数目的UMD PDU给低层即MAC层,并为每个提交到低层的UMD PDU更新VT (US),同时,缓冲没有被提交到低层的SDU。 [0015] Currently, an unacknowledged mode data PDU (UMD PDU) transmission process: the sender RLC the UM entity is received in unacknowledged mode data transfer request level after the sender scheduling received from an upper layer to an RLC service data unit (SDU) is transmitted; if one or more RLC SDU has been scheduled to transmit, the RLC UM entity notifies the lower layer first receives data including the number and size of the SDU from an upper layer; then, according to the RLC UM entity PDU size indicative of the lower layer SDU segments, may be performed if the cascade; after setting the sequence number field to VT (US), a length indication field is provided for each end of the SDUs in the UMD PDU; Finally, the number of requests submitted to the lower layer of the MAC UMD PDU layer, and a lower layer to be submitted for each UMD PDU update VT (US), while the buffer was submitted to the lower layer SDU.

[0016] UMD PDU的接收过程是:接收方RLC UM实体从低层收到一组UMD PDU后,该RLC UM 实体根据接收到的UMD PDU更新VR(US);如果VR(US)的更新步长不等于1,则丢弃在丢失的UMD PDU中有分段的SDU,否则,重组接收到的UMD PDU为RLC SDU,并提交重组后的RLC SDU给高层即RRC层。 [0016] UMD PDU reception procedure that is: after receiving side RLC UM entity receives UMD PDU from a lower layer group, the RLC UM entity according to the UMD PDU update VR (US) received; if the VR (US) updating step it is not equal to 1, with a segment is discarded in the missing UMD PDU SDUs, otherwise, recombinant received UMD PDU to RLC SDU, and submits the RLC SDU to the upper layers i.e. recombinant RRC layer.

[0017] 具体来说,发送方RLC UM实体的发送流程在当前一个修改周期开始后,执行以下步骤: [0017] Specifically, the transmitting procedure transmitting side RLC UM entity after the start of the current modification period, perform the following steps:

[0018] 步骤Al、当前修改周期开始,在第一个重复周期内,MCCH的高层,即RRC将需要发送的控制信息通过SDU发送给RLC UM实体,RLC UM实体接收到SDU后,执行步骤A2。 [0018] Step Al, after the start of the current modification period, a repetition period in the first, high-level the MCCH, i.e. RRC control information to be transmitted is transmitted to the RLC UM entity SDU, RLC UM entity receives SDUs, step A2 .

[0019] 步骤A2、RLC UM实体对所收到的SDU进行分段/级联处理,组装成非确认模式数据协议数据单元(UMD PDU),以下简称PDU。 [0019] Step A2, RLC UM entity of the received SDU segmentation / concatenation processing, assembly into an unacknowledged mode data PDU (UMD PDU), hereinafter referred to as PDU.

[0020] 其中,UMD PDU的格式如表一所示: [0020] wherein, UMD PDU format shown in Table I:

[0021]Sequence Number ELength Indicator E Length Indicator EData PAD Octl(Optional)(Optional) (Op tional)Last Ocetet [0021] Sequence Number ELength Indicator E Length Indicator EData PAD Octl (Optional) (Optional) (Op tional) Last Ocetet

[0022]表一 [0022] Table I

[0023] 在RLC协议UMD PDU的格式中,使用长度指示(Li,Length hdicator)标志RLC SDU在该PDU中结束的位置,LI除了一些预先定义的特殊值外,表示UMD PDU中RLC头部结束位置到RLC SDU在本PDU的最后一个字节的字节数,LI为7位或15位。 [0023] UMD PDU in the RLC protocol format, a length indicator (Li, Length hdicator) flag RLC SDU ended in the PDU positions, LI Except for some predefined value, indicating the end of the RLC UMD PDU header RLC SDU position to the number of bytes in the present PDU is the last byte of, LI of 7 bits or 15 bits. 对于UM模式, 如果最大的UMD PDU大小<=125字节,则使用7位的Li,其他情况使用15位Li。 For UM mode, if the size of the largest UMD PDU is <= 125 bytes, using a 7 Li, otherwise use 15 Li. 7位LI 和15位LI每个特殊值的含义分别如表二、表三所示,表二为7位LI每个特殊值的含义描述,表三为15位LI每个特殊值的含义描述。 7 LI 15 and LI meaning of each special value are shown in Table II, III shown in Table II for the meaning of each special value of 7 LI of description, Table 3 gives the 15 LI meaning of each special value described .

[0027] 表三 [0027] Table III

[0028] 由于包含准则信息的SDU和包含非准则信息的SDU不可以级联到同一个PDU中, 因此在本步骤中,RLC UM实体需要实时区别每个所接收SDU的信息类型,并根据SDU的信息类型进行分段/级联处理,即:对于包括准则信息的SDU进行分段/级联处理,组装成包括准则信息的协议数据单元(PDU),对于包括非准则信息的SDU进行分段/级联处理,组装成包括非准则信息的PDU。 [0028] Since the non-SDU containing SDU information contained guidelines criteria information may not cascaded to the same PDU, so in this step, RLC UM entity distinct types require real-time information of each received SDU and according SDU the types of information segmentation / concatenation process, namely: segmentation / concatenation process includes criteria for SDU information, assembled into a protocol data unit (PDU) comprises a guideline information performs non criteria for SDU comprises information segment / concatenation processing, assembled into PDU including non-criteria information.

[0029] 步骤A3、RLC UM实体为组装成的PDU设置序列号,通过一条MCCH逻辑信道向MAC 层发送组装成的PDU,并判断所发送的PDU中是否包括准则信息,如果是,则在RLC UM实体内保存该包括准则信息的PDU,否则,不保存该PDU。 [0029] Step A3, RLC UM entity arranged to be assembled into a PDU sequence number, the transmission of the assembled PDU to the MAC layer through a logical channel MCCH, and determines whether the transmitted PDU includes information criterion, if so, the RLC save the information in a PDU including guidelines UM entity, otherwise, do not save the PDU.

[0030] 在现有技术中,包括准则信息的PDU和包括非准则信息的PDU共同使用同一个序列号空间。 [0030] In the prior art, the information including criteria PDU and PDU including non-common criteria information using the same sequence number space. 以7位空间为例,一个序列号空间包括的序列号为:0〜127。 In the space 7, for example, a sequence number is the sequence number space comprising: 0~127.

[0031] 步骤A4、MAC层将MCCH逻辑信道映射到物理层的FACH传输信道发送PDU。 [0031] Step A4, MAC layer, a logical channel MCCH is mapped to the transport channel FACH transmission physical layer PDU. 此时,一个重复周期结束。 In this case, a repeat cycle.

[0032] 步骤A5,判断当前修改周期是否结束,如果是,则执行步骤A7 ;否则,将下一个重复周期作为当前重复周期,执行步骤A6。 [0032] Step A5, determines whether the end of the current modification period, if yes, performing step the A7; otherwise, the next repetition period as the current repetition period, perform Step A6.

[0033] 步骤A6、RLC UM实体在当前重复周期内,接收RRC传送来的SDU,区别所接收SDU 的信息类型,对于包括准则信息的SDU不再作处理,直接向MAC层发送RLC UM实体内所保存的、包括准则信息的PDU,并返回步骤A4 ;对于包括非准则信息的SDU进行分段/级联处理,组装成PDU,为该PDU设置序列号,并向MAC层发送该PDU,并返回步骤A4。 [0033] Step A6, RLC UM entity in the current repetition period, receiving the RRC SDU transmitted, the type of information received SDU distinction, including criteria for SDU information no longer be treated, the RLC UM entity is directly transmitted to the MAC layer the saved PDU including criteria information, and returns to step A4; segmentation / concatenation processing criteria for SDU information comprises a non-assembled into a PDU,, and transmits the PDU sequence number set for the PDU the MAC layer, and returns to step A4. 在本重复周期中,为包括非准则信息PDU设置的序列号与上一重复周期的PDU的序列号属于同一个序列号空间,但是取值不同。 In the present repetition period, the sequence number of non-criteria information comprising PDU PDU sequence number set to a repetition period of the sequence number space belong to the same, but different values.

[0034] 步骤A7、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体所保存的PDU删除,并对状态参数清零,返回步骤Al。 [0034] Step A7, the next modification period as the current modification period, reconstruct RLC UM entity, i.e. the above RLC UM entity PDU stored delete, and clear state parameter returns to step Al.

[0035] 与发送方RLC UM实体相对应,在接收方RLC UM实体中,在当前一个修改周期开始后,执行以下步骤: [0035] with the transmitting side RLC UM entity corresponding to the receiving side RLC UM entity, after the start of the current modification period, perform the following steps:

[0036] 步骤Bl、当前修改周期开始,并在第一个重复周期内,RLC UM实体每收到一个PDU都试图重组出相关的SDU,按照序列号保存该PDU,将重组出的SDU提交到RRC层。 [0036] Step Bl, current modification period starts, and in the first repetition period, RLC UM entity tries each receive a PDU related to a recombinant SDU, save the PDU according to the sequence number, the SDU is submitted to a recombinant RRC layer. 此时,一个重复周期结束。 In this case, a repeat cycle.

[0037] 步骤B2、判断当前修改周期是否结束,如果是,则执行步骤B4 ;否则,将下一个重复周期作为当前重复周期,执行步骤B3。 [0037] Step B2, is determined whether the end of the current modification period, if yes, executing step B4; otherwise, the next repetition period as the current repetition period, perform Step B3.

[0038] 步骤B3、在当前重复周期内,根据收到PDU的序列号判断与该序列号相同的PDU 是否已经保存,如果是,则丢弃收到的PDU,返回步骤B2 ;否则,试图将该PDU重组出相关的SDU,按照序列号保存该PDU,并将重组出的SDU提交到RRC层,返回步骤B2。 [0038] Step B3, in the current repetition period, is determined according to the sequence number of the received PDU is the same whether the PDU sequence number has been saved, if yes, discard the received PDU, returns to step B2; Otherwise, the attempt to the related recombinant PDU SDU, save the PDU according to the sequence number, and the SDU is submitted to recombinant RRC layer returns to step B2.

[0039] 步骤B4、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体所保存的PDU删除,并对状态参数清零,返回步骤Bl。 [0039] Step B4, the next modification period as the current modification period, reconstruct RLC UM entity, ie above RLC UM entity delete the saved PDU, and state parameters cleared and return to step Bl.

[0040] 但是,在上述现有技术方案中,存在如下的问题: [0040] However, in the above-described prior art embodiment, there is a problem:

[0041] 1、由于包括准则信息的SDU和包括非准则信息的SDU使用相同的序列号空间,因此对RLC UM实体的序列号有严格限制,不能绕回使用。 [0041] 1, the SDU information includes guidelines and criteria include non-SDU information using the same sequence number space, so there are strict limits on the sequence number of the RLC UM entity, it can not be used around the back. 例如对于7位序列号空间而言,假设每个重复周期有60个包括准则信息的PDU,20个包括非准则信息的PDU ;假设在第一个重复周期使用第0〜59个序列号表示包括准则信息的PDU,第60〜79个序列号表示包括非准则信息的PDU ;在第二个重复周期,包括准则信息的PDU内容不变,RLC UM实体重传前一重复周期保存的PDU,对于新的包括非准则信息的PDU,则采用新序列号来发送,即不能使用以前的第0〜79个序列号,需分配新的序列号。 For example, the sequence number space 7, it is assumed that there are 60 per repetition period information includes guidelines PDU, 20 comprises a non-PDUs criteria information; 0~59 assuming a first sequence number represents the first repetition period comprising PDU criteria information, the sequence number indicates 60~79 PDU comprises a non-criteria information; in the second repetition period, PDU including the same criteria information, RLC UM entity retransmits the saved PDU previous repetition period, for the new criteria information comprising a non-PDUs, the new sequence number is transmitted, i.e., not using the previous sequence number of 0~79, need to be allocated a new sequence number. 因此,包括非准则信息PDU所能使用的序列号只有第79〜127个,如果一个修改周期内的重复周期较多,则现有的序列号不够用,需要对序列号空间的位数进行扩展,而序列号又占用PDU的头开销,因此会增大PDU的头开销,降低信息传输效率,增加成本。 Thus, the guideline information including the serial number of non-PDU can be used by only one of 79~127, more if a repeat period within the modification period, the existing sequence number is not enough, the number of bits required for the sequence number space to be extended , and the sequence number PDU header overhead and occupy, and therefore increases header overhead of PDU, reduce the information transmission efficiency, an increase in cost.

[0042] 2、对于非准则信息的序列号不能绕回使用,因为接收方不区分是否为包括准则信息还是非准则信息的PDU,如果非准则信息的序列号绕回使用,例如,第一个重复周期中序列号为60〜79,接收方保存该序列号,第二个重复周期继续绕回使用该序列号60〜79表示新的PDU,则接收方就会因为保存了该序列号而将该新的PDU丢弃,造成数据接收错误。 [0042] 2, to the sequence number of non-wraparound guideline information can not be used, because the receiver does not distinguish whether the PDU to include a guideline information or non criteria information, if the sequence number of the non-wraparound guideline information, for example, a first repeat cycle 60~79 sequence number, the sequence number stored recipient, the second repetition period to continue to use the sequence number wrap-around 60~79 represent new PDUs, the recipient will be stored as the serial number and the the new PDU is discarded, resulting in a data reception error.

[0043] 3、由于发送方RLC UM实体需要实时区别每个所接收SDU的信息类型,并根据SDU 的信息类型分别进行分段/级联处理,因此RLC UM实体在传输信息时的处理过程复杂,计算量大,效率低,性能不高。 [0043] 3, since the transmission side RLC UM entity needs to distinguish each type of information in real time of the received SDU, and segmentation / concatenation processing according to the type of the SDU information, respectively, and therefore RLC UM entity processing for transmitting information complex , computationally intensive, inefficient, performance is not high.

[0044] 4、另外,由于现有的技术方案没有明确准则信息和非准则信息的调度方法,因此当准则信息和非准则信息同时到达RLC UM实体,或者当在一个修改周期的第二个重复周期及后继重复周期内,在重传准则信息PDU时,一旦有非准则信息到达,则RLC UM实体可能先发送包含准则信息的PDU,而非准则信息被延时发送。 [0044] 4. Further, since the prior art solutions without clear guidelines and non-scheduling method for an information criterion information, and so when non guideline information guideline information simultaneously arrive RLC UM entity, or when repeated in a second modification period and subsequent repetition cycle period, at retransmission PDUs criteria information, once the non-arrival information criterion, the RLC UM entity may send the first message contains PDUs guidelines, the guideline information is not transmitted delayed. 在极端的情况下,一个接入信息周期内的包括非准则信息的PDU可能在下一个接入信息周期才被发送下去,由此会导致MBMS的非准则信息,也即接入信息,被UE延时接收到,从而影响计数过程中UE的行为,降低计数的准确度、延长计数过程,降低系统的性能。 In an extreme case, a non-access criteria information including a PDU in the next cycle of information may be transmitted down was only access info period, which will lead to the non-MBMS information criterion, i.e. the access information, the UE extended when received, the counting process to affect the behavior of the UE, and reduce the accuracy of counting, the counting process extension, reducing the performance of the system. 发明内容 SUMMARY

[0065] 下面结合附图和具体实施例进一步说明本发明的实施方法。 Drawings and specific examples further illustrate the process of the present invention [0065] The following binding.

[0066] 本发明的核心思想为:在业务控制信息的传输过程中,对于其中需周期性重复发送的信息和不需周期性重复发送的信息,分别互相独立的进行分段/级联和编号等处理操作后发送,其中分别利用独立的序列号空间进行编号,并分别利用不同的逻辑信道中传输; 在接收方分别对需周期性重复发送的信息和不需周期性重复发送的信息进行接收重组处理。 [0066] The core idea of ​​the invention is: during transmission service control information, and information for periodically repeating the transmission without the need of periodically repeating the transmission of which, independently of one another each segmentation / concatenation number and Once the transmission processing operation, wherein each with a separate sequence number space are numbered, and the use of different logical channels are transmitted; information and receive data without transmitting periodically repeating recipient respectively transmitted periodically repeated for an restructuring process.

[0067] 本文中以MBMS控制信息中的准则信息和非准则信息为例对本发明进行说明。 [0067] As used herein to non-MBMS control information and the criterion information in the criterion of the present invention will be described as an example. 其中的准则信息为需周期性重复发送的信息,非准则信息为不需要周期性发送的信息。 Wherein the information required criteria information is repeatedly transmitted periodically, non-periodically guideline information transmitted information is unnecessary.

[0068] 基于上述核心思想,本发明的第一实施例在产生业务控制消息的逻辑实体RRC中建立两个链路层逻辑实体RLC,分别用来处理准则信息和非准则信息。 [0068] The core idea of ​​the above, a first embodiment of the present invention to establish a logical link layer two logical entity RLC entity generates service control RRC message, respectively, for processing information and non guidelines criteria information. 并通过两条逻辑信道传输该信息,再由MAC层将两条逻辑信道复用到一条FACH上传输信息。 And transmits the information via two logical channels, and then by the MAC layer two logical channels multiplexed to transmit information on a FACH. 该第一实施例中, MBMS控制信息的传输方法主要包括发送方RLC UM实体的发送过程,和接收方RLC UM实体的接收过程。 In this first embodiment, the MBMS control information transmission method includes transmitting process RLC UM entity of the sender, receiver and reception of the RLC UM entity.

[0069] 参见图8A,为本第一实施例所述控制信息传输方法在发送方的执行流程图,其中, 发送方RLC UM实体在当前一个修改周期开始后,执行以下步骤: [0069] Referring to Figure 8A, a first embodiment of the present method for transmitting the control information in the flowchart is executed sender, wherein the transmitting side RLC UM entity after the start of a modification period, perform the following steps in this:

[0070] 步骤8A1、当前修改周期开始,在第一个重复周期内,MCCH的高层,即RRC区分需要发送的控制信息的类型,将包括准则信息的SDU发送给所述处理准则信息的RLC UM实体, 将包括非准则信息的SDU发送给所述处理非准则信息的RLC UM实体;RLC UM实体接收到SDU后,执行步骤8A2。 [0070] Step 8A1, the current modification period starts, in the first repetition period, the MCCH high-level, i.e. the type of control information need to be transmitted RRC distinguishing the SDU comprises information transmitted to the guidelines criteria information processing RLC UM entity, the SDU including non-criteria information to the RLC UM entity processing non-criteria of the information; after receiving the RLC UM entity SDU, step 8A2.

[0071] 步骤8A2、处理准则信息的RLC UM实体和处理非准则信息的RLC UM实体分别地、 相互独立地对各自所收到的SDU进行分段/级联处理,组装成PDU。 [0071] Step 8A2, RLC UM entity and RLC UM entity processing non criteria for processing information criterion information, respectively, each independently of each received SDU segmentation / concatenation processing, assembled into a PDU.

[0072] 由于包含准则信息的SDU和包含非准则信息的SDU不可以级联到同一个PDU中, 因此本发明相对于现有技术,分别用两个RLC UM实体对不同信息类型的控制信息进行独立的分段/级联处理,避免了在分段/级联处理过程中,需要实时区别每个所接收SDU的信息类型,大大简化了分段/级联的处理过程,降低了RLC UM实体的计算量,提高了RLC UM实体的工作效率和整体性能。 [0072] Since the non-SDU containing SDU information contained guidelines criteria can not be cascaded to the same information in a PDU, therefore the present invention with respect to the prior art, respectively, two RLC UM entity of the control information of different information types independent segmentation / concatenation processing, avoids the segmentation / concatenation process, each type of information require real-time difference of the received SDU, greatly simplifies the process of segmentation / concatenation, the RLC UM entity is reduced the calculation and improve the efficiency and overall performance of the RLC UM entity.

[0073] 步骤8A3、所述处理准则信息的RLC UM实体和处理非准则信息的RLCUM实体分别利用不同的序列号空间、相互独立地为各自组装成的PDU设置序列号,并分别通过不同的MCCH逻辑信道发送组装成的PDU到MAC层,并且,处理准则信息的RLC UM实体还要保存该所发送的PDU。 [0073] Step 8A3, the criterion information processing and RLC UM entity processing non guidelines RLCUM entity information using different respective sequence number space, independently of one another are each assembled into a PDU sequence number is provided, and respectively different MCCH transmitting a PDU assembled into logical channels to the MAC layer, and the process of the RLC UM entity criterion information but also to save the PDU sent.

[0074] 在本发明中,包括准则信息的PDU和包括非准则信息的PDU分别使用两个不同的序列号空间。 [0074] In the present invention, a PDU including guideline information and criteria information comprises non-use two different PDU sequence number space. 以7位空间为例,两个个序列号空间包括的序列号都可以为:0〜127。 In the space 7, for example, two sequences SEQ ID number space that can be included: 0~127. 但是由于在传输信息的过程中,两个RLC UM实体的处理过程相互独立,因此不会由于序列号发生冲突。 However, since the process of transmitting information, the process two RLC UM entities independent of each other, since the sequence numbers it will not conflict. 相对于现有技术,减轻对序列号的限制。 With respect to the prior art, to reduce the restrictions on the sequence number. 例如:对于7位序列号空间而言,包括准则信息PDU的序列号数量限制为1¾个,包括非准则信息PDU的序列号数量限制为1¾个, 而现有技术中对于7为序列号空间而言,包括准则信息PDU和非准则信息PDU的序列号数量之和的限制为1¾个,因此,本发明降低了序列号数量的限制,并间接的降低了序列号空间的位数,从而降低PDU的头开销,提高传输效率。 For example: 7-bit sequence number space, the quantity comprising the sequence number of the PDU guideline information 1¾ number, a serial number including the number of non-limiting guideline information to 1¾ a PDU, the prior art for the sequence number space 7 made, including the serial number and the number of non-limiting guidelines and guideline information message PDU PDU for 1¾ one, therefore, the present invention reduces the number of sequence number limit, and indirectly reduces the number of bits of the sequence number space, thereby reducing the PDU the head expenses, improve transmission efficiency.

[0075] 步骤8A4、MAC层将所述的两条MCCH逻辑信道复用到物理层上的一条FACH信道上,即在收到来自RLC实体的PDU后,根据传输该PDU的逻辑通道判断该PDU包括的信息类型,并在该PDU中标明其包括的信息类型,通过所述FACH信道发送PDU。 [0075] Step 8A4, MAC layer, the two MCCH logical channels multiplexed into one FACH channel on the physical layer, i.e., after receiving the PDU from the RLC entity, determining whether the PDU transmitted according to the logical channel a PDU It includes type information and indicating the type of information included in the PDU, the PDU transmitted by the FACH channel. 此时,一个重复周期结束。 In this case, a repeat cycle.

[0076] 本步骤中,为了增加乱序传输功能,本发明还需要MAC层能增加两条MCCH逻辑信道的复用功能。 [0076] In this step, to increase the scrambled transmission function, the present invention also requires the MAC layer can be increased two MCCH logical channel multiplexing function. 本发明中MAC层的MAC协议使用C/T域来区分相同MCCH类型的不同逻辑信道,也即区分包括不同信息类型的PDU。 In the present invention, the MAC layer using a MAC protocol C / T field to distinguish between different logical channels of the identical MCCH type, i.e. to distinguish between different types of information including the PDU. 例如,可以用1个比特的C/T域来区分两条MCCH 逻辑信道,C/T域的取值可以为:0或1,当取值为0时:表示用于传送非准则信息,当取值为1时:表示用于传送准则信息。 For example, the two MCCH logical channels may be distinguished by one bit C / T field, the value C / T field may be: 0 or 1, when the value of 0: means for transmitting a non-criterion information when when the value is 1: represents a criterion for transmitting information.

[0077] 本发明的C/T域还可以有其他实现的方式,例如,从扩展的角度看,可以用2个比特来表示c/τ域,但原理是类似的。 [0077] C according to the present invention / T field may also be implemented in other ways, for example, from the expansion point of view, can be represented by two bits c / τ domain, but the principle is similar.

[0078] 相应的,MAC层将所述的两条MCCH逻辑信道复用到物理层上的一条FACH信道上后,对所述的PDU扩展为MAC PDU的格式后传输给接收方,MAC PDU的格式如表四所示:[0079] [0078] appropriate, the MAC layer after the two MCCH logical channels multiplexed into one FACH channel on the physical layer, the PDU is transmitted to the receiver is extended after the MAC PDU format, the MAC PDU format as shown in table 4: [0079]

[0080] 表四 [0080] Table IV

[0081] 另外,本发明中MAC层实现两条MCCH逻辑信道的复用功能也可以不使用C/T域, 而是采用两个TCTF取值来来区分相同MCCH类型的不同逻辑信道,即:在基于现有技术的TCTF的编码中,采用两个取值分别标识用于传输准则信息的MCCH逻辑信道和用于传输非准则信息的逻辑信道。 [0081] Further, the present invention is implemented in the MAC layer two MCCH logical channel multiplexing function may not be used C / T field, instead of using two different logical channels to be distinguished TCTF values ​​MCCH same type, namely: TCTF-based encoding in the prior art, MCCH logical channels using the two values ​​are used to transmit the identification information and a criterion for the transmission of non-logical criterion information. 现有技术中FACH信道上TCTF的编码如表五所示: TCTF prior art FACH channel coded as shown in Table 5:

[0084] 本发明中FACH信道上TCTF的编码如表六所示: [0084] In the present invention, the FACH channel TCTF six coding tables as shown:

[0085] [0085]

Figure CN101115231BD00103

[0086] 表六 [0086] Table VI

[0087] 上述表六中,用01000001标识传送准则信息的MCCH逻辑信道,用01000010标识传送非准则信息的MCCH逻辑信道,因此只用TCTF取值既可来区分相同MCCH类型的不同逻辑信道,当然,这只是一种实施方式,类似的,还可用其他两个不同的TCTF编码取值区分传送准则信息的MCCH逻辑信道和传送非准则信息的MCCH的逻辑信道。 [0087] In the above Table VI, the logical channel MCCH information transmitted by the identification criteria 01000001, 01000010 MCCH logical channel identification information with the non-transmission criteria, and therefore can only TCTF values ​​to distinguish between different types of logical channels MCCH same, of course, , this is just one embodiment, a similar, but also with the other two values ​​to distinguish between different coding TCTF MCCH logical channel MCCH logical channel transmission and non-transmission guideline information criterion information.

[0088] 对于上述采用两个TCTF取值来来区分相同MCCH类型的不同逻辑信道的方法,其相应的MAC PDU的格式如表4所示: [0088] For the above-described method employs two TCTF values ​​to distinguish between different logical channels of the identical MCCH type, the corresponding MAC PDU format shown in Table 4:

[0089] [0089]

Figure CN101115231BD00111

[0090] 表4[0091 ] 对于MCCH类型的两条MCCH逻辑信道,要求用来传送非准则信息的MCCH逻辑信道比用来传送准则信息的MCCH逻辑信道有更高的优先级。 [0090] Table 4 [0091] For the two MCCH logical channel MCCH type, non-criteria required for transmitting MCCH information for the logical channel over a logical channel MCCH information transmission criteria has a higher priority. MAC层在进行调度时,优先调度用来传送非准则信息的MCCH逻辑信道的数据。 When performing the MAC layer scheduling, data for the non-transmission information criterion MCCH logical channel priority scheduling.

[0092] 步骤8A5,判断当前修改周期是否结束,如果是,则执行步骤8A7;否则,将下一个重复周期作为当前重复周期,执行步骤8A6。 [0092] Step 8A5, determines whether the end of the current modification period, if yes, performing step 8A7; otherwise, the next repetition period as the current repetition period, perform Step 8A6.

[0093] 步骤8A6、在当前重复周期内,RRC请求处理准则信息的RLC UM实体重传其保存的包括准则信息的PDU,处理准则信息的RLC UM实体收到请求后,直接发送自身保存的PDU 给MAC层,返回步骤8A4 ;同时,RRC将包括非准则信息的SDU发送给所述处理非准则信息的RLC UM实体;该处理非准则信息的RLC UM实体对收到的SDU进行分段/级联处理,组装成包括非准则信息的PDU,为该PDU设置序列号,然后发送该PDU给MAC层,返回步骤8A4。 [0093] Step 8A6, in the current repetition period, the RRC request processing criteria RLC UM entity information retransmitted PDU includes guideline information stored thereon, after receiving the request, sends its own direct PDU stored in the guideline information processing RLC UM entity to the MAC layer returns to step 8A4; the same time, the RRC SDU including non-criteria information to the RLC UM entity processing non-criteria of the information; guidelines for the treatment of non-RLC UM entity of the information received SDU segmenting / level linking treatment, a non-assembled into PDU includes information criteria, provided that the sequence number PDU, and then transmits the PDU to the MAC layer returns to step 8A4.

[0094] 在本重复周期中为包括非准则信息PDU设置的序列号与上一重复周期的PDU的序列号属于同一个序列号空间,但是取值不同。 [0094] The non guideline information comprises a sequence number of PDU and setting the sequence number of the PDU belonging to a repetition period of the same sequence number space in the present repetition period, but different values.

[0095] 步骤8A7、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体所保存的PDU删除,并对状态参数清零,返回步骤8A1。 [0095] Step 8A7, the next modification period as the current modification period, reconstruct RLC UM entity, ie above RLC UM entity delete the saved PDU, and state parameters cleared and return to step 8A1.

[0096] 参见图8B,与发送方RLC UM实体相对应,接收方RLC UM实体中,在当前一个修改周期开始后,执行以下步骤: [0096] Referring to Figure 8B, the transmitting side RLC UM entity corresponding to the receiving side RLC UM entity, after the start of the current modification period, perform the following steps:

[0097] 步骤8B1、当前修改周期开始,并在第一个重复周期内,MAC层每收到一个PDU后, 根据该PDU的C/T域判断该PDU的类型,即:是包括准则信息还是非准则信息,并通过一个MCCH逻辑信道将包括准则信息的PDU发送到处理准则信息的RLC UM实体,通过另一个MCCH 逻辑信道将包括非准则信息的PDU发送到处理非准则信息的RLC UM实体。 After [0097] Step 8B1, current modification period starts, and in the first repetition period, the MAC layer of each of a received PDU, the PDU according to the C / T field determines the type of the PDU, namely: including information or criteria non criteria information, and through a logical channel MCCH information including criteria PDU to RLC UM entity processing guideline information through another logical channel MCCH criteria include non-PDU information to the RLC UM entity processing non-criteria information.

[0098] 步骤8B2、处理准则信息的RLC UM实体和处理非准则信息的RLC UM实体分别接收和处理收到的PDU,其中: [0098] Step 8B2, processing the RLC UM entity guideline information and RLC UM entity processing non-criteria receiving and processing information received PDU, respectively, wherein:

[0099] 处理准则信息的RLC UM实体每收到一个PDU都试图重组出相关的SDU,按照序列号保存该PDU,并将重组出的SDU提交到RRC层;处理非准则信息的RLC UM实体每收到一个PDU只试图重组出相关的SDU,并将重组出的SDU提交到RRC层。 [0099] The processing of the RLC UM entity guideline information every time it receives a PDU associated with the tries recombinant SDU, save the PDU according to the sequence number, and submits an RRC SDU of the recombination layer; criteria information processing non RLC UM entity per receive a PDU only seeking to restructure the associated SDU, and submit a reorganization of the SDU to the RRC layer.

[0100] 步骤8B3、此时,一个重复周期结束,判断当前修改周期是否结束,如果是,则执行步骤8B5 ;否则,将下一个重复周期作为当前重复周期。 [0100] Step 8B3, at this time, one repetition period ends, it is determined whether the end of the current modification period, if yes, performing step 8B5; otherwise, the next repetition period as the current repetition period. [0101] 步骤8B4、在当前重复周期内,处理准则信息的RLC UM实体和处理非准则信息的RLC UM实体分别接收和处理收到的PDU,其中: [0101] Step 8B4, in the current repetition period, RLC UM entity and RLC UM entity processing non guidelines criteria for processing information and processing information received PDU are received, wherein:

[0102] 处理准则信息的RLC UM实体每收到一个PDU,则根据所收到PDU的序列号判断与该序列号相同的PDU是否已经保存,如果是,则丢弃收到的PDU,返回步骤8B3,否则,试图将该收到的PDU重组出相关的SDU,按照序列号保存该PDU,并将重组出的SDU提交到RRC层, 返回步骤8B3 ; [0102] The processing of the RLC UM entity guideline information every time it receives a PDU is received according to the sequence number of the PDU is determined with the same whether the PDU sequence number has been saved, if yes, discard the received PDU, returns to Step 8B3 otherwise, the received PDU recombinant attempt the associated SDU, save the PDU according to the sequence number, and the SDU is submitted to a recombinant RRC layer returns to step 8B3;

[0103] 处理非准则信息的RLC UM实体每收到一个PDU,则直接试图重组出相关的SDUJf 重组出的SDU提交到RRC层,返回步骤8B3。 [0103] Processing of non guideline information to each received RLC UM PDUs entity, directly related to an attempt to recombinant SDUJf recombinant SDU is submitted to the RRC layer returns to step 8B3.

[0104] 步骤8B5、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体所保存的PDU删除,并对状态参数清零,返回步骤8B1。 [0104] Step 8B5, the next modification period as the current modification period, reconstruct RLC UM entity, ie above RLC UM entity delete the saved PDU, and state parameters cleared and return to step 8B1.

[0105] 上述本发明的第一实施例采用两种RLC UM实体分别对准则信息和非准则信息进行分段/级联、编号和重组等处理,并用两种逻辑信道分别传输。 [0105] The first embodiment of the present invention using two RLC UM entities are non guidelines and guideline information on information segmentation / concatenation, numbering and reorganization process, and transmitted using two logical channels, respectively.

[0106] 本发明也可采用一种RLC UM实体分别对准则信息和非准则信息进行分段/级联、 编号和重组等处理,并用两种逻辑信道分别传输,具体参见下述的第二实施例。 [0106] The present invention may also be employed for one kind of RLC UM entity criteria are criteria information and non-information segmentation / concatenation, numbering and reorganization process, and transmitted using two logical channels, respectively, refer to a second specific embodiment described below example.

[0107] 参见图9A,为本第二实施例所述控制信息传输方法在发送方的执行流程图,本第二实施例在RLC UM实体中设置两个处理模块,分别处理准则信息和非准则信息。 [0107] Referring to Figure 9A, a second embodiment of the present method for transmitting the control information in the execution of the flowchart of the sender, a second embodiment according to the present embodiment is provided two RLC UM entity processing module, the processing guidelines are criteria information and non- information. 其中,发送方在当前一个修改周期开始后,执行以下步骤: Wherein the sender after the start of the current modification period, perform the following steps:

[0108] 步骤9A1、当前修改周期开始,在第一个重复周期内,MCCH的高层,即RRC将需要发送的控制信息通过SDU发送给RLC UM实体,其中,将包括准则信息的SDU发送到RLC UM实体中处理准则信息的模块,将包括非准则信息的SDU发送到RLC UM实体中处理非准则信息的模块。 [0108] Step 9A1, current modification period starts, in the first repetition period, the MCCH high-level, i.e., the RRC control information to be sent to the transmitting RLC entity through the UM SDU, wherein the SDU comprises information transmitted to the RLC criteria UM entity processing module information criteria, including the criteria of non-SDU information to the module in the RLC UM entity processing non-criteria information.

[0109] 步骤9A2、RLC UM实体中的两个不同的模块对包括准则信息的SDU和包括非准则信息的SDU分别单独地进行分段/级联处理,即:处理准则信息的模块对包括准则信息的SDU进行分段/级联处理,组装成包括准则信息的协议数据单元(PDU);处理非准则信息的模块对包括非准则信息的SDU进行分段/级联处理,组装成包括非准则信息的PDU。 [0109] Step 9A2, RLC UM entity of two different modules individually perform segmentation / concatenation processing of the SDU including non-SDU and criteria information includes information criteria, namely: a guideline information processing module including the criteria SDU information are segmentation / concatenation process to assemble a protocol data unit (PDU) comprises a guideline information; means for processing non-SDU information includes guidelines criteria information are non-segmentation / concatenation process, the non-assembled to include a criterion PDU information.

[0110] 步骤9A3、所述处理准则信息的模块和处理非准则信息的模块分别利用不同的序列号空间、相互独立地为各自组装成的PDU设置序列号,并分别通过不同的MCCH逻辑信道发送组装成的PDU到MAC层,并且,处理准则信息的模块还要保存该所发送的PDU。 [0110] Step 9A3, the processing module and the module processing non guideline information are information with different sequence number space, independently of one another are each assembled into a PDU sequence number is provided, and transmitted via respective different logical channels MCCH assembled into a PDU to the MAC layer, and the guideline information processing module also save the PDU sent.

[0111] 步骤9A4、MAC层将所述的两条MCCH逻辑信道复用到物理层上的一条FACH信道上,通过该FACH信道发送包括准则信息的PDU和包括非准则信息的PDU。 [0111] Step 9A4, MAC layer, the two MCCH logical channels multiplexed into one FACH channel on the physical layer, transmitting PDU includes information of the guidelines and criteria information includes the non-FACH channel PDU. 此时,一个重复周期结束。 In this case, a repeat cycle.

[0112] 与上述第一实施例相同,本步骤中,为了支持乱序传输功能,MAC层将所述的两条MCCH逻辑信道复用到物理层上的一条FACH信道上后,对所述的PDU扩展为MAC PDU的格式后传输给接收方,其MAC PDU的格式如上述表四所示。 [0112] the same as the first embodiment described above, the two MCCH logical channels multiplexed into one FACH channel on the physical layer in the present step, in order to support scrambled transmission capabilities, MAC layer according to, for the extended PDU transmitted to the receiver after the MAC PDU format, which the MAC PDU format shown in table 4 above.

[0113] 另外,对于MCCH类型的两条MCCH逻辑信道,要求用来传送非准则信息的MCCH逻辑信道比用来传送准则信息的MCCH逻辑信道有更高的优先级。 [0113] Further, the two MCCH logical channel MCCH type, MCCH logical channel for transferring non-required criteria for transferring information over the logical channel MCCH information criterion has higher priority. MAC层在进行调度时,优先调度用来传送非准则信息的MCCH逻辑信道的数据。 When performing the MAC layer scheduling, data for the non-transmission information criterion MCCH logical channel priority scheduling.

[0114] 步骤9A5,判断当前修改周期是否结束,如果是,则执行步骤9A7;否则,将下一个重复周期作为当前重复周期,执行步骤9A6。 [0114] Step 9A5, determines whether the end of the current modification period, if yes, performing step 9A7; otherwise, the next repetition period as the current repetition period, perform Step 9A6. [0115] 步骤9A6、在当前重复周期内,RRC请求RLC UM实体中处理准则信息的模块重传其保存的包括准则信息的PDU,处理准则信息的模块收到请求后,直接发送自身保存的PDU给MAC层,返回步骤9A4 ;同时,RRC将包括非准则信息的SDU发送给所述处理非准则信息的模块;该处理非准则信息的模块对收到的SDU进行分段/级联处理,组装成包括非准则信息的PDU,为该PDU设置序列号,然后发送该PDU给MAC层,返回步骤9A4。 [0115] Step 9A6, in the current repetition period, the RRC request processing module in the RLC UM entity guideline information retransmission PDU includes information saved by the guidelines, the guideline information processing module after receiving the request, transmits its stored PDU directly to the MAC layer returns to step 9A4; the same time, the RRC processing to the non-criteria module comprising information SDU information to the non-criterion; means the process of non-criterion information is received SDU segmentation / concatenation processing, assembly guidelines to include a non-PDU information, provided that the sequence number PDU, and then transmits the PDU to the MAC layer returns to step 9A4.

[0116] 在本重复周期中为包括非准则信息PDU设置的序列号与上一重复周期的PDU的序列号属于同一个序列号空间,但是取值不同。 [0116] The non guideline information comprises a sequence number of PDU and setting the sequence number of the PDU belonging to a repetition period of the same sequence number space in the present repetition period, but different values.

[0117] 步骤9A7、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体所保存的PDU删除,并对状态参数清零,返回步骤9A1。 [0117] Step 9A7, the next modification period as the current modification period, reconstruct RLC UM entity, ie above RLC UM entity delete the saved PDU, and state parameters cleared and return to step 9A1.

[0118] 参见图9B,与发送方相对应,接收方在当前一个修改周期开始后,执行以下步骤: [0118] Referring to Figure 9B, the transmitting side corresponding to the receiving side after the start of the current modification period, perform the following steps:

[0119] 步骤9B1、当前修改周期开始,并在第一个重复周期内,MAC层每收到一个PDU后, 根据该PDU的C/T域判断该PDU的类型,即:是包括准则信息还是非准则信息,并通过一个MCCH逻辑信道将包括准则信息的PDU发送到RLCUM实体中处理准则信息的模块,通过另一个MCCH逻辑信道将包括非准则信息的PDU发送到RLC UM实体中处理非准则信息的模块。 After [0119] Step 9B1, current modification period starts, and in the first repetition period, the MAC layer of each of a received PDU, the PDU according to the C / T field determines the type of the PDU, namely: including information or criteria non criteria information, and through a logical channel MCCH information including criteria RLCUM entity PDU to the processing module guideline information through another logical channel MCCH criteria include non-PDU information to the RLC UM entity processing non guideline information module.

[0120] 步骤9B2、处理准则信息的模块和处理非准则信息的模块分别接收和处理收到的PDU,其中: [0120] Step 9B2, the processing module and the module processing non-criterion information criterion separately receive and process information received PDU, wherein:

[0121] 处理准则信息的模块每收到一个PDU都试图重组出相关的SDU,按照序列号保存该PDU,并将重组出的SDU提交到RRC层;处理非准则信息的模块每收到一个PDU只试图重组出相关的SDU,并将重组出的SDU提交到RRC层。 [0121] guideline information processing module receives a PDU tries each recombinant the associated SDU, save the PDU according to the sequence number, and submits an RRC SDU of the recombination layer; non guideline information processing modules each receive a PDU only seeking to restructure the associated SDU, and submit a reorganization of the SDU to the RRC layer.

[0122] 步骤9B3、此时,一个重复周期结束,判断当前修改周期是否结束,如果是,则执行步骤9B5 ;否则,将下一个重复周期作为当前重复周期。 [0122] Step 9B3, at this time, one repetition period ends, it is determined whether the end of the current modification period, if yes, performing step 9B5; otherwise, the next repetition period as the current repetition period.

[0123] 步骤9B4、在当前重复周期内,处理准则信息的模块和处理非准则信息的模块分别接收和处理收到的PDU,其中: [0123] Step 9B4, in the current repetition period, and the module processing non guidelines guideline information processing module receives and processes information received PDU, wherein:

[0124] 处理准则信息的模块每收到一个PDU,则根据所收到PDU的序列号判断与该序列号相同的PDU是否已经保存,如果是,则丢弃收到的PDU,返回步骤3,否则,试图将该收到的PDU重组出相关的SDU,按照序列号保存该PDU,并将重组出的SDU提交到RRC层,返回步骤9B3 ; Module [0124] The processing information for each criterion a PDU is received, it is judged in accordance with the received PDU sequence number is the same whether the PDU of the sequence number has been saved, if yes, discard the received PDU, and return to step 3, otherwise attempt to receive the PDU related to a recombinant SDU, save the PDU according to the sequence number, and the SDU is submitted to a recombinant RRC layer returns to step 9B3;

[0125] 处理非准则信息的模块每收到一个PDU,则直接试图重组出相关的SDU,将重组出的SDU提交到RRC层,返回步骤9B3。 [0125] Non guideline information processing modules each receive a PDUs, directly related to the SDU attempt recombinant, recombinant SDU is submitted to the RRC layer returns to step 9B3.

[0126] 步骤9B5、将下一个修改周期作为当前修改周期,重建RLC UM实体,即将上述RLC UM实体中处理准则信息模块所保存的PDU删除,并对RLC UM实体的状态参数清零,返回步骤9B1。 [0126] Step 9B5, the next modification period as the current modification period, reconstruct RLC UM entity, i.e. the above RLC UM entity processing module guideline information stored PDU deleted, and the state of the RLC UM entity Parameter clear returns to step 9B1.

[0127] 由于现有技术方案中没有针对包含准则信息的PDU和包含非准则信息的PDU的调度方法,本发明还公开了一种信息传输方法,在对SDU信息进行处理的过程中,如果在处理某种类型的SDU信息时,收到另一种类型的SDU信息且新收到的SDU信息需要优先处理,则中断对当前SDU信息的处理,先对新收到的SDU信息进行处理,新收到的SDU信息处理完毕后,再继续处理中断的SDU信息。 [0127] Since no prior art embodiment for a PDU containing scheduling method and criteria information comprising a non-PDU criteria information, the present invention also discloses a method for information transmission, in the course of processing of SDU information, if the when dealing with a certain type of SDU information received another type of SDU SDU information and the new information received priority treatment, processing of the current SDU information is interrupted, the first of the newly received SDU information processing, new after SDU received information processing is completed, and then continue processing the SDU information interrupts. 其中,所述SDU信息包括:SDU的所有分段和SDU结束位置标识。 Wherein the SDU information comprises: all segments of the SDU position identifier and SDU ends. 所述对SDU信息的处理包括分段级联和发送。 The processing of the SDU information comprises concatenation and transmission segment.

[0128] 这里,是否需要优先处理可以根据优先级确定,这种情况下,不同类型的SDU信息会对应不同的优先级;或是根据不同类型SDU信息的特性确定,比如:非准则信息需要优先于准则信息发送;或是根据当时的发送需求确定,比如:根据业务需要类型C的SDU信息要优先于类型A的SDU信息。 [0128] Here, if the priority according to priority determination process may, in this case, SDU information of different types may correspond to different priorities; or determined according to the characteristics of different types of SDU information, such as: non-priority criterion information send information to the guidelines; or according to the time of sending the demand to determine, for example: according to business needs SDU information of type C to give priority to the SDU information of type a. 下面均以根据SDU信息特性决定是否需要优先处理为例,进一步详细说明本发明的实现方案。 The following are the decision whether to prioritize an example, implementations described in further detail in accordance with the present invention SDU information characteristics.

[0129] 假设有两种类型的SDU =SDUl和SDU2,根据两类SDU信息的特性,SDU2需要优先于SDUl处理,那么,本发明中SDU信息的分段级联和发送的过程分为两种情况: [0129] Suppose there are two types of SDU = SDUl and SDU2, according to the characteristics of the two types of information SDU, SDU2 SDUl priority in processing, then the present invention, segmentation and concatenation of SDU information transmission process is divided into two Happening:

[0130] 第一种是,当前发送方实体正在分段级联和发送的SDU为SDU1,新收到SDU为SDU2,这种情况下,又可以有两种处理方式:①中断对SDUl的分段级联与发送,先对SDU2进行分段级联和发送,之后,再继续SDUl的分段级联与发送;②继续完成对SDUl的分段级联, 但对收到SDU2后封装出的PDU存储而不发送,然后对SDU2进行分段级联和发送;SDU2的所有信息发送完之后,再发送SDUl的剩余分段,即所存储的对应SDUl的所有PDU。 [0130] The first is that the current sender entity is transmitted SDU segmentation and concatenation of SDU1, SDU2 newly received SDU is, in this case, and can be handled in two ways: ① break points of the SDUl segment transmission cascade, for the first segment of the SDU2 concatenation and transmission, then, to continue transmitting SDUl cascade segment; ② proceed to SDUl concatenation of segments, but after receiving a package of SDU2 PDU stored without transmitting, and then transmits SDU2 segmentation and concatenation; SDU2 after all the information is transmitted and the retransmission of SDUl remaining segments, i.e. all the PDU corresponding to SDUl stored. 比如:UM 发送实体需要发送一个非准则信息SDU时,如果当前缓冲区中有准则信息SDU,且该准则信息SDU的一部分已被分段/级联处理,封装在PDU中发送过了,还剩余一部分没有被处理, 则UM发送实体先将该准则信息SDU剩余的数据进行分段/级联处理,封装成PDU,并存储这些封装的PDU ;然后,UM发送实体将需要发送的非准则信息SDU进行分段级联处理,封装成PDU发送;发送完非准则信息SDU封装成的PDU后,再发送存储的准则信息SDU封装成的PDU。 For example: UM sending entity transmit information when a non-SDU criterion, if the current buffer information criterion SDU, and a portion of the SDU has been guideline information segmentation / concatenation processing, after sending the encapsulated in the PDU, there remains part is not processed, the UM sending entity to the SDU remaining guideline information data segmentation / concatenation processing, encapsulated PDU, and the PDU storing package; then, UM sending entity to be transmitted to the non-SDU guideline information concatenation processing is segmented, encapsulated PDU transmission; after transmitting the non-encapsulated guideline information SDU into PDU, and then transmits the stored package guideline information SDU into PDU.

[0131] 第二种是,当前发送方实体正在分段级联和发送的SDU为SDU2,新收到SDU为SDU1,这种情况下,只需按顺序依次对先后收到的SDU2和SDUl进行分段级联,封装成PDU 发送即可。 [0131] The second is that the current sender entity is transmitted SDU segmentation and concatenation of SDU2, the newly received SDU SDU1 is, in this case, simply according to the order of the successively received and SDUl for SDU2 segment concatenation, can be encapsulated into the PDU transmission.

[0132] 本发明中,不能将不同类型的SDU信息级联在同一个PDU中,比如:不能将非准则信息SDU和准则信息SDU级联到同一个PDU中发送。 [0132] In the present invention, it can not be concatenated SDU information of different types in the same PDU, such as: can be non-SDU guidelines and criteria information SDU concatenated information into the same PDU transmitted. 这里,所述PDU是指WCDMA/TD-SCDMA RLC协议下UM模式中的UMD PDU。 Here, the UMD PDU UM PDU refers to the WCDMA / TD-SCDMA RLC protocol mode. 所述的SDU信息是指SDU的分段、或SDU的结束位置标识、或二者的组合,也就是说,不能将一个非准则信息SDU的分段与一个准则信息SDU的分段级联到同一个PDU中,同样,也不能一个非准则信息SDU的结束位置标识与一个准则信息SDU的分段级联到同一个PDU中,反之亦然。 It refers to the SDU information of the SDU segment or end of the SDU position identifier, or combinations of both, that is, not a non-segmented segment concatenation information with a guideline SDU to the SDU information same PDU, the same can not be a criterion of non-end position of SDU information identifying a segment SDU concatenation guideline information into the same PDU, and vice versa.

[0133] 假设第一SDU和第二SDU分别代表不同类型的SDU,且第二SDU要优先于第一SDU 处理,那么,本发明所提出的信息传输方法的基本思想就是: [0133] Assuming that the first SDU and second SDU represent different types of SDU, a second SDU and the first SDU to priority processing, then, the basic idea of ​​the proposed information transmission method of the present invention is:

[0134] 发送方实体判断当前要处理的SDU中是否同时包括第一SDU和第二SDU,如果同时包括第一SDU和第二SDU,则发送方实体先对第二SDU进行分段级联,封装成PDU并编号发送,然后再对第一SDU进行分段级联和发送,并且,在分段级联和发送过程中,如果收到第二SDU,则中断对第一SDU的处理,先对第二SDU进行分段级联和发送,之后,再继续对第一SDU的处理;如果仅包括第二SDU,则发送方实体直接对第二SDU进行分段级联,封装成PDU 并编号发送;如果仅包括第一SDU,则对第一SDU进行分段级联和发送,并且,在分段级联和发送过程中,如果收到第二SDU,则中断对第一SDU的处理,先对第二SDU进行分段级联和发送,之后,再继续对第一SDU的处理。 [0134] SDU sender entity determines whether the current to be processed while the first SDU and second SDU, while if the first SDU and second SDU, the transmitting entity first side of the second segment the SDU concatenation, encapsulated PDU sent and number, and then to the first SDU segmentation and concatenation transmit, and, in the segment concatenation and a transmission process, if a second SDU is received, the interrupt processing of the first SDU, the first the second segment of the SDU concatenation and sending, after processing of the first SDU continue; if it only comprises a second SDU, the sender entity directly to the second segment the SDU concatenation, numbering and PDU encapsulated transmission; comprises only if the first SDU, the first SDU segmentation and concatenation transmit, and, in the segment concatenation and a transmission process, if a second SDU is received, the interrupt processing of the first SDU, the second segment of the SDU to be concatenated and transmitted, after the treatment was continued for the first SDU.

[0135] 实际上,在第一SDU分段级联和发送过程中,有可能多次收到第二SDU,多次中断对第一SDU的处理,插入对第二SDU的处理;也有可能只插入一次,而一次包括多个第二SDU,总之,无论哪种情况,处理原则都一致,中断对第一SDU的处理,优先处理第二SDU,处理完第二SDU后,再继续第一SDU的处理。 [0135] In fact, in the process of transmitting a first segment and SDU concatenation, it is possible repeatedly received a second SDU, repeatedly interrupting the processing of the first SDU and second SDU is inserted into the process; it is also possible only once inserted, and a plurality of second SDU once, in short, in either case, principles are the same, the interrupt processing of the first SDU and second SDU priority, after processing the second SDU, and then continue to the first SDU processing.

[0136] 另外,这里的第一SDU和第二SDU并不固定对应某种类型,也就是说,并不限定第一SDU仅对应类型A的SDU信息,第二SDU仅对应类型B的SDU信息,第一SDU和第二SDU 是相对而言的。 [0136] Further, where the first SDU and second SDU corresponding to a certain type is not fixed, that is to say, not limited to the first SDU corresponding to the SDU information of only the type A, corresponding to only the second SDU SDU information of Type B , the first SDU and second SDU is a relative term. 举个具体例子来说,有A、B、C三个类型的SDU信息,优先处理的顺序是:C 类型优先于B类型且B类型优先于A类型。 By way of specific example, there are A, B, C three types of SDU information, the order of priority is: C type takes precedence over Type B Type B and Type A precedence. 那么,在对A类型SDU信息进行处理的过程中, 如果收到B类型SDU信息,则中断对A类型SDU信息的处理,先对B类型SDU信息进行处理, 此时,第一SDU指A类型SDU信息,第二SDU指B类型SDU信息;如果在B类型SDU信息的处理过程中,又收到C类型SDU信息,则中断对B类型SDU信息的处理,先对C类型SDU信息进行处理,此时,第一SDU指B类型SDU信息,第二SDU指C类型SDU信息。 Then, in the process of the A type SDU information is processed, if the type of SDU information B is received, the interrupt processing of the SDU information of Type A, Type B of SDU information to be processed at this time, the first SDU refers to the type A SDU information, the second SDU refers to SDU information of type B; B in the process if the type of the SDU information was received, the type of SDU information C, the interrupt processing of the SDU information of type B, type C prior to the SDU information processing, At this time, the first SDU refers to SDU information of type B, the second SDU refers to SDU information of type C. 总而言之,只要遵循先处理需要优先处理的SDU信息的原则即可。 All in all, simply follow the SDU information processing needs first priority of the principle can be. 可以在第一SDU的处理过程中,插入一次或多次、一个或多个相同类型的SDU,也可以在第一SDU的处理过程中,插入一次或多次、一个或多个不同类型的SDU。 In the process of the first SDU can, insert one or more times with one or more of the same type of SDU, it may be in the process of the first SDU, inserting one or more one or more different types of SDU .

[0137] 以UM发送实体处理准则信息SDU和非准则信息SDU为例,如图10所示,本发明所提出的信息传输方法包括以下步骤: [0137] In transmitting UM entity processing non guidelines and guideline information SDU SDU information, for example, shown in Figure 10, the information transmission method proposed in the present invention comprises the steps of:

[0138] 步骤101、RRC层向RLC UM实体发送SDU,RLC UM实体判断是否同时接收到至少两个SDU,如果是,则执行步骤102 ;否则,执行步骤105。 [0138] Step 101, RRC layer sends the RLC UM entity SDU, RLC UM entity determines whether the at least two simultaneously received SDU, if yes, execute step 102; otherwise, step 105 is performed.

[0139] 步骤102、判断这些SDU中是否有非准则信息SDU,如果有非准则信息SDU,则执行步骤103,否则,执行步骤104。 [0139] Step 102, it is determined whether or not these non-SDU SDU information criterion, if non-SDU information criterion, step 103 is executed, otherwise, step 104 is performed.

[0140] 步骤103、优先调度处理该非准则信息SDU,具体就是:对非准则信息SDU进行分段/级联,封装成PDU,进行编号等操作,并发送封装成的PDU。 [0140] Step 103, the non-priority scheduling criterion information processing SDU, specifically is: the SDU of non guideline information segmentation / concatenation, encapsulated PDUs, and other operations are numbered, and transmits the encapsulated PDU.

[0141] 步骤104、调度处理准则信息SDU,具体就是:对该准则信息SDU进行分段/级联, 封装成PDU,进行编号,并发送封装成的PDU ;在此过程中,RLC UM实体实时监测是否接收新的非准则信息SDU,如果有,则中断对当前准则信息SDU的处理,立即调度处理所收到的新的非准则信息SDU,并发送由该非准则信息SDU封装成的PDU,之后再继续处理中断的准则信息SDU以及其他的准则信息SDU,结束当前处理流程。 [0141] Step 104, the scheduling information of the processing criteria SDU, specifically that: the criterion for information SDU segmentation / concatenation, encapsulated PDUs, numbered, and packaged into PDUs sent; in this process, RLC UM entity in real-time monitoring whether the received new SDU of non guideline information, if there is, then interrupt the processing of SDU information of the current guidelines, new non-scheduling process criteria SDU received information immediately, and transmits the non-encapsulated by the SDU into PDUs guideline information, before continuing interrupt handling guidelines SDU information and other information criterion SDU, ending the current process.

[0142] 这里,所述的中断处理可以是中断分段级联和发送,也可以是仅中断发送。 [0142] Here, the interrupt process may be interrupted and the transmission cascade segments, may only interrupt transmission.

[0143] 步骤105、判断接收到的SDU是否为准则信息SDU,如果为非准则信息SDU,则对该非准则信息SDU进行处理,具体就是:进行分段/级联,封装成PDU,进行编号等操作,并发送封装成的PDU ;如果为准则信息SDU,则对该准则信息SDU进行调度处理发送,并在该过程中,RLC UM实体实时监测是否接收新的非准则信息SDU,如果有,则中断对当前准则信息SDU的处理,立即调度处理所收到的新的非准则信息SDU,并发送由该非准则信息SDU封装成的PDU,之后再继续处理中断的准则信息SDU以及其他的准则信息SDU0 [0143] Step 105 determines whether the received SDU is SDU information criterion, if non-SDU information criterion, the criterion of the non-SDU information processing, specifically is: segmentation / concatenation, encapsulated PDUs, numbered and other operations and packaged into the PDUs transmitted; if the SDU information as a criterion, the criterion is the SDU information transmission scheduling process, and in the process, RLC UM entity monitors in real time whether the received new SDU of non-information criterion, and if so, interrupting the processing of the current SDU guideline information, the scheduling of new non guideline information received SDU processing immediately, and transmits the non-encapsulated by the guideline information SDU into PDUs, before continuing the interrupted processing guideline information and other criteria SDU information SDU0

[0144] 这里,所述的中断处理可以是中断分段级联和发送,也可以是仅中断发送。 [0144] Here, the interrupt process may be interrupted and the transmission cascade segments, may only interrupt transmission.

[0145] 以不同类型的SDU信息为非准则信息SDU和准则信息SDU为例,举例说明本发明信息传输方法的具体实现。 [0145] SDU information of different types of SDU information guidelines and criteria for non-SDU information, for example, specific implementation illustrated an information transmission method of the present invention. 这里,非准则信息SDU要优先于准则信息SDU处理。 Here, the non guidelines SDU information to give priority to the guidelines SDU information processing.

[0146] 如图11所示,UM发送实体当前正在分段级联和发送的SDU为准则信息SDU,该准则信息SDU封装成的PDU以点填充,在收到非准则信息SDU之前,该准则信息SDU已封装出七个PDU,序列号分别为1至7 ;收到非准则信息SDU后,UM发送实体就中断对准则信息SDU 的分段级联和发送,而开始对非准则信息SDU进行分段级联,封装成序列号为8的PDU,然后,发送序列号为8的PDU ;发送完毕后,UM发送实体继续对准则信息SDU的剩余部分进行分段级联和发送,封装出序列号为9至14的PDU,并顺序发送序列号为9至14的PDU。 [0146] As shown, the UM sending entity 11 is currently sent SDU segmentation and concatenation of SDU information criterion, the criterion information is encapsulated into a PDU SDU point fill, before receiving a non-SDU information criterion, the criterion seven out of SDU information already encapsulated PDUs, sequence numbers 1 to 7 respectively; guideline information after receiving the non-SDU, the UM sending entity transmits and interrupts the cascade segment of the SDU guideline information, start information of the SDU non guidelines segment concatenation, serial No. encapsulated PDU 8, and then the transmission sequence number of the PDU 8; after completion of transmission, the UM sending entity continue the segmentation and concatenation transmit the remainder of the guideline information of the SDU, a sequence package number PDU 9 to 14, and sequentially transmits the sequence number of PDU 9 to 14.

[0147] 如图12所示,UM发送实体当前正在分段级联和发送的SDU为准则信息SDU,该准则信息SDU封装成的PDU以点填充,在收到非准则信息SDU之前,该准则信息SDU已封装出七个PDU,序列号分别为1至7 ;收到非准则信息SDU后,UM发送实体继续完成对该准则信息SDU剩余部分的分段级联,封装出序列号为8至13的PDU,但对于序列号为8至13的PDU 并不发送,而是将序列号为8至13的PDU存储;然后,对非准则信息SDU进行分段级联,封装成序列号为14的PDU,封装完后立即发送序列号为14的PDU ;发送完毕后,UM发送实体再顺序发送自身存储的序列号为8至13的PDU。 [0147] As shown, the UM sending entity 12 is currently sent SDU segmentation and concatenation of SDU information criterion, the criterion information is encapsulated into a PDU SDU point fill, before receiving a non-SDU information criterion, the criterion seven out of SDU information already encapsulated PDU, the sequence numbers are 1 to 7; guideline information after receiving the non-SDU, UM sending entity continue to complete the remaining portion of the segment concatenation SDU guideline information, a sequence number of packages to 8 PDU 13, the PDU 8-13 but is not transmitted to the sequence number, but the sequence number of the PDU stored 8-13; then, non-segmented SDU concatenation information criterion, encapsulated serial No. 14 the PDU, the package immediately after the transmission sequence number of the PDU 14; after completion of transmission, UM sending entity then sequentially transmits its stored sequence number PDU 8 to 13.

[0148] 为了保证发送实体在收到高层发来的SDU后,能马上进行分段级联和发送,可预先设置所封装的PDU的固定值。 [0148] In order to ensure the sending entity after receiving the SDUs to higher layers, segment concatenation and transmission can be performed immediately, the encapsulated PDU fixed value may be set in advance. 那么,UM发送实体在收到每个SDU后,就根据固定值对所收到的SDU进行分段级联处理,将每个SDU封装成一个或一个以上固定大小的PDU。 Then, the UM sending entity after receiving each SDU, an SDU can be received segment concatenation processing according to a fixed value, each SDU encapsulated into one or more fixed PDU size. 这种情况下,每当有PDU发送时,可根据所要求的数目调度PDU进行发送,在调度时,只要缓冲区中有需要优先处理的SDU信息如非准则信息SDU的PDU,则先发送需要优先处理的SDU信息对应的PDU。 In this case, every time a PDU transmission may be transmitted in accordance with the required number of PDU scheduling, when scheduling, the buffer as long as necessary information such as priority of the SDU is SDU of non-PDU guideline information, the first transmission needs PDU SDU information corresponding to the priority.

[0149] 本发明所提出的信息传输方法不仅适用于MCCH控制信息,所有存在不同发送顺序且发送类型不同SDU信息的情况,所有包括不同优先级SDU信息的情况等等,都可以使用本发明所述方法完成信息传输。 [0149] An information transmission method proposed by the present invention is applicable not only to the MCCH control information, the transmission order and all have different types of SDU information of different transmission circumstances of each case different priorities SDU comprises information, etc., the present invention may be used said method transmitting completion information.

[0150] 以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此, 任何熟悉该技术的人在本发明所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。 [0150] above, the present invention is merely preferred specific embodiments, but the scope of the present invention is not limited thereto, and any person skilled in the art within the technical scope disclosed by the present invention can be easily thought of changes or replacements shall fall within the protection scope of the present invention.
