具体实施方式 Detailed ways

[0028] 下面结合本发明实施例对应的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0028] Next, in conjunction with the present invention corresponding to the drawings embodiment, the technical solutions in the embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention rather than all embodiments .

[0029] 本发明实施例所提供的技术方案要解决问题包括:背景技术中进行CS业务的业务帧(如语音帧或数据帧等)传输都基于CS域网络,使得业务帧的传输独占通讯信道(如每时隙保持1或2个语音呼叫),造成信道资源的浪费和网络容量的瓶颈。 [0029] The technical solutions provided in embodiments of the present invention is to solve the problem comprising: a traffic frame CS service in the background art (e.g., speech frame or data frame, etc.) transmissions based on CS-domain network, so that the transmission service frame exclusive communication channel (e.g., each slot holding one or two voice calls), and a waste of network capacity bottlenecks of channel resources.

[0030] 为此,本发明实施例中提出了使用分组网络来承载CS域业务(例如语音业务)的方案,对原有的CS业务的协议栈进行修改,即在L2采用RLC/MAC协议代替原有的LAPDm协议,如图1所示,图中左侧为基于原CS域传输语音业务的协议分层结构,右侧为本发明实施例中的传输CS域业务的网络的协议分层结构。 [0030] To this end, the present invention has been proposed embodiment uses a packet bearer network CS domain service (e.g., voice traffic), the protocol stack of the existing CS service is modified, i.e. using RLC / MAC protocol in place of L2 original LAPDm protocol, the protocol is a layered protocol structure of FIG left layered structure based on the original transmission of the CS domain voice service, the right side in the present embodiment the transmission network CS domain service of the embodiment of the invention shown in FIG. . 其中,用以承载CS域业务的分组网络,比如可以是GSM EDGE无线接入网(GSM EDGE Radio Access Network,GERAN),在分组域允许用户复用于多个时隙,也允许每时隙复用多个用户。 Wherein the packet network to the CS domain bearer service, such as may be a GSM EDGE radio access network (GSM EDGE Radio Access Network, GERAN), packet domain in a plurality of slots for allowing a user multiplexing also allows multiplexing per slot with multiple users.

[0031] 本发明实施例中,由于CS业务承载于分组网络,因此CS业务可以采用更高的语音编码速率,甚至可以引入16QAM和32QAM等高阶调制方式,并可从而实现CS之间、CS/PS之间的复用和资源共享。 [0031] The embodiments of the present invention, since the CS service carried in the packet network, the CS service and therefore may be employed higher voice coding rate, 16QAM and 32QAM can be introduced even higher order modulation, etc., and can achieve between CS, CS / reuse and sharing of resources between the PS.

[0032] 本发明ー种电路交換域业务的传输方法的第一具体施例的流程图,如图2所示, 本实施例包括: [0032] The present invention ー flowchart of a first specific embodiment of the method for transmitting a circuit switched service domain species, shown in Figure 2, the present embodiment includes:

[0033] 步骤201 :为CS域业务建立基于块调度的连接; [0033] Step 201: establishing a connection block scheduling is based on CS domain service;

[0034] 所述CS域业务可以包括语音业务,也包括数据业务。 The [0034] CS domain service may include voice services, including data services. 一般来说,块调度过程可以包括:当多个用户复用同一信道,或某个用户复用多个信道吋,在上下行由网络侧来确定各个时隙的块资源分配给哪个用户。 Generally, block scheduling process may include: when a plurality of users multiplexed in the same channel, or a plurality of user channels multiplexed inch, assigned to which users in the uplink and downlink of each time slot is determined by the network side block resources. 下行由网络直接分配,上行通过USF来指配各个用户的上行块资源,所述基于块调度的连接可以是临时块流(Temporary Block Flow,TBF)和类似TBF的连接。 Direct downlink assigned by the network, the uplink blocks to assign uplink resources to each user through the USF, the connection block based scheduling may be a temporary block flow (Temporary Block Flow, TBF), and the like TBF connection. 具体的,即对ー个CS域业务,在空ロ建立上下行TBF连接或类TBF连接;从而在网络侧可以对CS域业务帧(或对CS域业务帧编码后形成的RLC/MAC块)进行上下行调度,即采用动态块调度的方式调度空ロ资源。 Specifically, namely ー a CS domain service, to establish the uplink and downlink TBF connection or class TBF connection empty ro; so that the network side can be the CS domain service frame (or RLC formed after the CS domain service frame encoding / MAC block) uplink and downlink scheduling, i.e. scheduling ro empty resource block scheduling dynamic manner. 采用空ロ资源动态调度CS域业务,使得ー个电路交換域业务可以在多个时隙上传输,或者多个电路交換域业务在相同的时隙上复用, 或者电路域业务和分组域业务在相同的时隙上复用。 Ro dynamic scheduling resources using empty CS domain service such ー a circuit switched domain traffic may be transmitted over multiple slots, or a plurality of circuit switched domain services multiplexed on the same time slot, or a circuit domain and packet domain service multiplexed on the same time slots.

[0035] 步骤202 :将所述电路交換域业务以块调度方式在空ロ进行时分复用调度,将所述电路交換域业务进行时分复用后在所述连接上传输或将电路交換域与分组交換域业务进行时分复用后在所述连接上传输。 [0035] Step 202: the circuit switched domain service block scheduling mode for scheduling time division multiplexing ro empty, after the time-multiplexed circuit switched domain service transmitted on the connection or the circuit switched domain and after the packet switched domain services on the connection time-multiplexed transmission. 其中,所述的空ロ是指分组交換域的空ロ,现有电路交换域业务中进行业务传输时是不能实现复用的,也就不存在能进行时分复用调度的空ロ。 Wherein ro is the empty space means a packet switched domain ro, when traffic transmission in the conventional circuit-switched service domain multiplexing can not be achieved, there would be no space can be time-multiplexed ro scheduling.

[0036] 在将CS域业务进行复用吋,由于需要将多个业务复用到同一信道上或几个信道上,如,将三个业务通过两个信道进行传输,每个业务不是独占的使用某一信道,因此需要对多个业务在多个信道上的传输进行调度,以便实现多个业务时分复用的实现在多个信道上有效的进行传输。 [0036] In the CS domain service multiplexing inch, since a plurality of services are multiplexed on the same channel or several channels, e.g., three services are transmitted via two channels, each traffic not exclusive use of a channel, so the need for multiple service scheduling transmissions in a plurality of channels, time division multiplexing operations in order to achieve a plurality of channels are implemented in a plurality of valid transmission.

[0037] 其中,在PS域的空ロ进行调度吋,遵循调度策略: [0037] wherein, in an empty scheduling inch ro PS domain, scheduling policy follows:

[0038] 在进行上、下行调度吋,当CS和PS域业务进行复用吋,优先将CS域业务进行复用并传输,即将多个CS域业务进行时分复用后传输。 The [0038] performing downlink scheduling inch, when CS and PS service domain multiplexing inch, preferentially CS domain service multiplexing and transmitted, a plurality of CS domain service soon after time division multiplex transmission.

[0039] 由于要将CS域业务承载在PS域网络,所以需要对CS域业务进行有别于原有CS 域业务的编码,根据具体进行的编码方式的不同,复用调度的方式也有所区別,下面对具体的情况分别进行描述。 [0039] To the CS domain since the bearer service in the PS domain network, a CS domain service is needed to encode the CS domain service is different from the original, depending on the specific coding scheme performed, multiplexing scheduling is also somewhat different manner the following specific conditions are described.

[0040] 可基于本发明实施例一,如图3所示,为对CS域业务进行RLC编码后复用的情況, 包括: [0040] may be based on an embodiment of the invention, shown in Figure 3, for the case where the CS domain service after the RLC-code multiplexing, comprising:

[0041] 步骤301 :为CS域业务建立基于块调度的连接。 [0041] Step 301: establishing a connection block scheduling is based on CS domain service.

[0042] 步骤302 :对CS域业务进行RLC编码,其中,经过RLC编码后的CS域业务中包含USF域禾ロTFI域。 [0042] Step 302: the CS domain service for RLC coding, wherein, after the CS domain service after the USF field contains coded RLC Wo ro TFI field.

[0043] 本步骤具体可包括: [0043] This step may specifically include:

[0044] 将现有语音编码速率映射到RLC编码方式,利用RLC块中的剰余比持,对CS域承载的业务帧(即CS业务内容)进行编码(如纠错编码),提高链路性能; [0044] The speech encoding rate prior to mapping encoded RLC mode, RLC blocks I use for Surplus holding ratio of traffic frames (i.e., CS service content) CS domain bearer is encoded (e.g., error correction encoding), to improve the link performance ;

[0045] 或是,对业务帧先进行缓存打包,然后再进行RLC编码发送。 [0045] or, for the first cache frame service package, and then to transmit RLC coding.

[0046] 在无线环境较好,复用度较高的场景下,利用高速率的RLC编码,在保证一定的语音质量和时延性能的前提下,可以进ー步提高系统容量。 [0046] In the preferred wireless environment, a high degree of multiplexing of the scene, a high rate coding using the RLC, to ensure a certain delay performance and voice quality of the premise, can further improve the system capacity ー feed. [0047] 由于通常情况下,传输的CS帧的长度比传输的PS块小得多,为了提高利用率,可将多个CS帧打包,再进行编码后传输。 [0047] As is usually the case, the length of the transmission frame CS PS block is much smaller than the transmission in order to improve efficiency, a plurality of frame packing CS, then coded transmission. 下面分别对CS域业务帧进行RLC编码和打包的过程进行详细说明: Next, the CS domain service frames were encoded RLC and packaging process described in detail:

[0048] 对CS域业务帧进行RLC/MAC编码过程,包括: [0048] The CS domain service frames RLC / MAC encoding process, comprising:

[0049] 对CS域业务帧的RLC编码可以不修改RLC/MAC头格式。 [0049] The RLC service frame encoding the CS domain may not modify the RLC / MAC header format. 对于承载在PS网络的语音业务,我们可以采用非持久性的确认模式(即只重传一次)。 For the PS bearer network voice services, we can use non-persistent acknowledgment mode (i.e., only one retransmission). 在此过程中同样可以使用快速应答报告(Fast Ack/Nack Reporting, FANR)技术,减少重传所带来的时延。 The same report can be used to quickly answer in this process (Fast Ack / Nack Reporting, FANR) technology to reduce delay caused by retransmission.

[0050] 目前GSM 全速率(Full feite,FR)语音业务的速率为13kbit/s,半速率(Half Rate, HR)语音业务的速率为5. 6bits/s,增强型全速率(Enhanced Full Rate, EFR)语音业务的速率为12. 2kbit/s,自适应多速率编解码(Adaptive Multi-Rate Code, AMR)窄带(Narrow Band, NB)的速率为4· 75 〜12. 2kbit/s,而AMR 宽带(Wide Band, WB)的速率为6.60〜23.851ibit/S。 [0050] The rate of current GSM full rate (Full feite, FR) voice service of 13kbit / s, a rate of half-rate (Half Rate, HR) voice service to 5. 6bits / s, EFR (Enhanced Full Rate, EFR) voice service rate is 12. 2kbit / s, adaptive multi-rate codec (adaptive multi-rate Code, AMR) narrowband (Narrow Band, NB) at a rate of 4 · 75 ~12. 2kbit / s, and AMR broadband (Wide Band, WB) of the rate of 6.60~23.851ibit / S. 可以看出现有技术中的CS语音编码速率和无线链路控制(Radio Link Control, RLC)编码速率是不一致的,如果直接用PS网络承载业务帧,势必会造成带宽资源的浪费和性能的下降。 CS voice coding rate can be seen that the prior art and radio link control (Radio Link Control, RLC) coding rate is inconsistent, if the PS bearer service network frame directly, will inevitably lead to waste and decrease the performance of bandwidth resources.

[0051] 因此,为充分利用带宽,提升RLC承载业务帧的链路性能,本发明实施例利用RLC块的剩余比特,对承载的业务帧进行纠错编码,如循环冗余校验(Cyclic Redundancy [0051] Accordingly, in order to fully utilize the bandwidth to improve the link performance of the RLC frame bearer traffic, embodiments utilize the remaining bits of the RLC blocks, carried by the frame of the service of the present invention the error correction coding, such as cyclic redundancy check (Cyclic Redundancy

ChecK, CRしノο ChecK, CR shi Techno ο

[0052] 纠错编码的方式,以GSM FR为例,GSM FR的速率为13kbit/s,可以选择CS-2 (速率为13. 4kbit/s)或MCS-3 (速率为14. 8kbit/s)来承载FR业务帧。 [0052] The error-correction coding method, an example in GSM FR, GSM FR rate of 13kbit / s, can choose to CS-2 (rate of 13. 4kbit / s) or MCS-3 (rate of 14. 8kbit / s ) to carry traffic frame FR. 以MCS-3为例,加入业务帧后剰余比特数为36,我们可以利用该36比特来对承载的业务帧做纠错编码,以达到提高链路性能的目的,如表1所示: In MCS-3 as an example, after the addition of the traffic frame for Surplus remainder bit number is 36, we can use the 36 bits of the object of the bearer traffic frames do error correction coding, to achieve improved link performance, as shown in Table 1:

[0053] 表1 :承载FR业务帧的RLC块结构(MCS-3) [0053] Table 1: RLC block structure bearer service frame FR (MCS-3)

[0054] [0054]

Figure CN101674604BD00071

[0055] 相对于全速率语音业务,半速率语音业务中,每20ms包含两个用户的业务帧(即每业务帧占两个burst),而对HR业务帧进行RLC编码吋,每20ms数据块中只能承载同一用户的业务帧。 [0055] with respect to the full rate voice services, half-rate voice traffic, each user comprising two 20ms traffic frames (i.e., each frame occupies two Burst traffic), while the HR RLC traffic frame encoding inch, every 20ms block the user can carry the same traffic frames. 因此对HR业务帧的RLC编码吋,下行复用的两个HR用户,每20ms轮流调度; 对某ーHR用户,需要缓存前20ms的HR业务帧,然后将两个业务帧级联在一起,承载在同一RLC块内。 HR inch RLC therefore encoding traffic frames, the downlink user multiplexing two HR, every 20ms round robin; ー HR of a user, the business need HR 20ms frame front buffer, and then the two traffic frames concatenated together, carried in the same RLC blocks. 如此会造成20ms时延。 So will cause 20ms latency.

[0056] 例如GSM HR的速率为5. 6kbit/s,可以选择MCS-2来承载半速率语音业务。 [0056] For example the rate of GSM HR 5. 6kbit / s, MCS-2 can be selected to carry a half-rate voice traffic. MCS-2 的RLC编码速率为11.21ibit/S,正好可以用来承载两个HR业务帧(如下图所示),业务帧的级联直接首尾相连。 RLC coding rate of MCS-2 11.21ibit / S, HR just be used to carry two traffic frames (shown below), is directly connected end to end traffic frames cascade.

Figure CN101674604BD00081

[0059] 对AMR各模式的RLC编码,可采用类似的方法。 [0059] for encoding each RLC mode AMR, a similar method may be employed. 由于PS域带宽较高,在进行CS域的业务帧(即语音帧)在PS域传输吋,可以提高AMR语音编码传输速率。 Due to the high bandwidth of the PS domain, performing CS domain service frame (i.e., voice frames) in the PS domain transmission inch possible to improve the transmission rate AMR speech coding.

[0060] 如果对本发明实施例中所述的进行复用的CS业务采用非确认模式,则可以利用RLC头中有些域,如块序列号(Block Sequence Number, BSN)等,承载传输的链路的信息, 从而进一步提高该技术方案的链路性能。 [0060] If the example embodiment of the present invention using a CS service multiplexing unacknowledged mode, the RLC header may be utilized in some fields, such as a block sequence number (Block Sequence Number, BSN), etc., link transmission carrying information, thereby further improving the link performance of the technical solution.

[0062] PS域的高呑吐量是其较大的优势,特别是在GERAN演进之后。 [0062] High Throughput PS domain is its great advantage, especially after GERAN evolution. 在本发明实施例中所述的进行复用的CS/PS业务的基础上,我们可以利用PS域的高速率,在每个RLC/MAC块内承载更多的业务帧,这样可以在无线环境较好,复用度较高的场景下,利用高速率的RLC 编码,在保证一定的语音质量和时延性能的前提下,进ー步提高系统容量和频谱效率。 In the basic embodiment of the present invention the multiplexing of CS / PS service, we can use the high-rate PS domain, carry more traffic frames within each RLC / MAC block, which can in a wireless environment the better, higher degree of multiplexing of the scene, a high rate coding using the RLC, to ensure a certain delay performance and voice quality of the premise of the intake ー further improve the system capacity and spectral efficiency.

[0063] 以TCH FS为例,可以采用MCS-3承载单个业务帧。 [0063] In TCH FS as an example, MCS-3 frame carries a single service may be employed. 如果当前场景信道质量很好, 但复用度很高,我们可以采用MCS-6编码来承载连续两个业务帧(如下图所示)。 If the current scene good channel quality, but a high degree of multiplexing, we can use MCS-6 coding to carry two consecutive traffic frames (shown below). 这样就可以腾出一半的时间和资源,从而可以接入更多的CS或PS用户。 This will free up half the time and resources to access to more CS or PS users. 如表3所示为进行打包后再进行RLC编码后的待发送的包。 Table RLC packets after encoding to be packaged and then to be transmitted in Fig.

[0066] 步骤303 :经RLC编码的CS域业务在无线接ロ以块调度方式进行调度,并根据所述调度进行CS/PS复用的业务传输。 [0066] Step 303: The encoded RLC CS domain service in the radio access scheduling ro scheduling block, and traffic transmission CS / PS multiplexed according to the scheduling.

[0067] 调度通常包括下行调度(网络侧向用户侧方向称为下行)和上行调度(用户侧向网络侧方向称为上行)。 [0067] The scheduling generally includes a downlink scheduling (user side to the network side is called the downlink direction) and uplink scheduling (the user side to the network side is called the uplink direction). 下面分別说明这两种调度的调度策略。 We address each of these scheduling scheduling policy below.

[0068] 一、下行调度 [0068] First, downlink scheduling

[0069] 由于CS用户业务在建立的基于块调度的连接上进行传输,比如当CS用户业务采用非连续性发射(Discontinuous Transmission, DTX)机制时,对于ー个CS业务实际只有40%的时间有数据进行传输,所以传输过程中存在空闲的时间,因此,可以将各CS业务,以及CS业务和PS业务进行复用。 [0069] Since the establishment of the CS service users for transmission based on the connection block scheduling, such as when using non-CS continuity transmit user traffic (Discontinuous Transmission, DTX) mechanism, for a CS service ー actually has only 40% of the time data is transmitted, the idle time exists during transmission, and therefore, each of the CS service and the PS services and CS services can be multiplexed. 下面举两种情况为例,描述具体的复用调度的流程。 The following two cases cited as an example, a specific multiplexing scheduling process.

[0070] 1)、CS和PS复用调度 [0070] 1), CS and PS multiplexing scheduling

[0071] 当对CS和PS业务进行复用吋,调度采用CS业务绝对优先的原则。 [0071] When the CS and PS services are multiplexed inch, absolute priority scheduling using the principle of the CS service. 当CS用户无语音数据需要发送时,才对PS下行数据块进行复用传输。 When no CS voice user data to be transmitted, the downlink data block fishes PS multiplexing transmission. [0072] 2)、CS之间复用调度 [0072] 2), multiplexing scheduling between the CS

[0073] 若网络侧不支持同一时隙CS用户之间的复用,即不支持CS业务之间的复用,则无需实现CS用户之间的调度。 [0073] If the network does not support multiplexing between one slot CS user, i.e., does not support multiplexing between the CS service, CS scheduling between the user is not required to achieve. 若网络侧支持同一时隙CS用户之间的复用,则可将CS业务复用于多个信道,根据统计复用的原则(例如两个时隙上复用CS用户,3个用户同时通话的概率为6. 4%,4个用户中出现3个及以上用户同时通话的概率为17. 92%,同时通话概率小的信道之间可以进行复用),允许CS业务之间的复用。 If the network supports multiplexing between users of the same time slot CS, the CS can be multiplexed for a plurality of traffic channels, according to the principles of statistical multiplexing (e.g. multiplexing two slots CS users, while the user calls 3 probability of 6.4 percent, and the probability of three or more users at the same time the user calls for the presence of 4 17.92%, can be multiplexed between the talk probability while small channels), allowing multiplexing between the CS service . 当信道组上的复用度较高吋,如果出现CS业务帧下行调度的冲突,可以采用缓存的方式解決。 When a higher degree of multiplexing the channel-inch group, if the CS service scheduling conflict downlink frame, may be employed to resolve the cache.

[0074] 如果CS业务为半速率业务(服),由于在半速率业务中,调度(如MAC调度)是每20ms —次,20ms内需要调度两个CS业务的业务帧,即每个业务帧占用两个突发脉冲(burst),在下行尽量将复用的两个HR业务在20ms周期内一起调度。 [0074] If the CS service is a half rate service (service), since the half-rate traffic, a scheduler (e.g., MAC scheduler) per 20ms - views, two CS service needs to be scheduled within the 20ms traffic frames, i.e., each traffic frame occupies two bursts (burst), as far as possible the two HR service multiplexed together in a scheduling period of 20ms in the downlink. 当信道组内只复用了ー个HR业务,或者当前20ms内没有其它HR业务有数据进行传输吋,另外两个burst可以传送静默指示(Silence Descriptor, SID)帧(自己或其它HR业务的)。 When the channel group multiplex only the ー a HR service, or no other HR service data transmitted inch within 20ms current, the other two burst may transmit a silence indication (Silence Descriptor, SID) frame (own or other HR services) .

[0075] ニ、上行调度。 [0075] Ni, uplink scheduling.

[0076] 由于进行了RLC编码吋,在业务帧中已经编码了USF,所以在进行上行调度吋,可以根据已有的USF进行调度。 [0076] As a result of the RLC coding inch, in the traffic frame has been encoded the USF, uplink scheduling is performed so inch, may be scheduled according to existing USF.

[0077] 具体调度方式如下: [0077] DETAILED schedule as follows:

[0078] 根据需要设置向用户发送的CS域业务的业务帧中的USF,所述USF用于指示可在下一上行块上传业务帧的用户; [0078] The CS domain service is provided to transmit traffic frames to a user in need USF, the USF is used to indicate a user can upload service frame in the next uplink block;

[0079] 全速率的CS用户侧监听到自己的USF吋,可以在上行发送业务帧或SID帧。 [0079] CS full rate monitor user side to their USF inch frame can be transmitted in the uplink traffic frames or SID. 网络侧在收到该用户的SID帧之前,需要时刻给该用户调度其上行业务;当网络收到SID帧后, 表示该用户进入语音静默期,只需要周期性调度该用户的上行即可,例如每480ms调度ー次,调度的资源用于传输该用户的SID或业务帧;其它空闲的资源就可以分配给其它用户, 如将空闲的上行资源分配给复用的CS或PS用户;在这种情况下,如果网络侧在其上行收到该用户的正常业务帧,则表示该用户恢复到正常通话状态,这时需要时刻调度该用户的上行。 Before the network side receives the user SID frame, the user needs time to schedule its uplink service; SID frame is received when the network indicates that the user enters the voice silent period, the user need only periodically scheduled uplink can, for example, every 480ms scheduling ー times, schedule resources for the user service or SID frame transmission; other idle resources can be allocated to other users, such as uplink resource allocation to the CS or PS idle users multiplexed; in that the case, if the network side receives the user's normal service frame in which the uplink, it indicates that the user return to normal conversation state, then the time required to schedule the uplink user.

[0080] 半速率的CS用户监听到自己的USF吋,下一个上行块资源均属于该用户,这就需要用户侧缓存上ー个业务帧(每个业务帧承载在2个burst上),和当前的业务帧一起在下ー个上行块周期内发送出去。 [0080] CS half rate users listen to their USF inch, the next uplink resource blocks belong to the user, which requires a traffic frame ー (each traffic frame carried on two burst) on the user side cache memory, and with the next upstream ー current traffic frames transmitted within a block period. 也就是说上行块资源是在两个半速率用户之间轮流调度的。 That is, in the uplink resource block between two half-rate user scheduling turn. 和全速率类似,当两个半速率用户上行均处于静默期吋,则可以调度复用的CS和PS用户。 And the like full rate, half rate when two users are in uplink silence period inch, the user may schedule CS and PS multiplexing.

[0081] 与图3中所示的基于RLC编码后复用的情况相对的,如图4所示,为对CS域业务进行有别于现有CS域业务的编解码后传输的情況,相应的流程包括: [0081] Based on the situation after the multiplexed encoded RLC opposite, as shown, for the CS domain service after transmission codec different from the existing CS domain service is shown in a case 4 shown in FIG. 3, the corresponding the process includes:

[0082] 401、为电路交換CS域业务建立基于块调度的连接。 [0082] 401, to the CS domain connection service establishment based block scheduling.

[0083] 402、网络侧对CS域业务进行新的信道编码,即对所述CS域业务中的业务帧格式的物理层传输数据进行编码。 [0083] 402, the CS domain service network a new channel coding, i.e. the physical layer transmission frame format of a data traffic service in the CS domain is encoded. 此处可不进行RLC编码,但是由于将CS域业务承载于PS域网络,所以需要对原来的CS域业务的编码方式进行一定的修改。 Here RLC may not be encoded, but since the CS domain to the PS domain service bearer network, requires some modifications to the original code of the CS domain service. 如,在CS域业务的业务帧格式中插入USF,或同时插入TFI等。 As inserted in the CS domain service traffic frame formats the USF, TFI, or the like while inserting.

[0084] 403、根据调度策略对所述经过编码的CS域业务在分组交換PS域的无线ロ以块调度方式进行调度,井根据所述调度进行CS/PS复用的业务传输。 [0084] 403, according to the scheduling policy of the encoded CS domain service in a wireless packet switched PS domain ro block scheduling mode for scheduling, traffic transmission wells CS / PS multiplexed according to the scheduling. 本步骤中的调度与图3中的实施例类似,也包括上行调度和下行调度,其中下行调度与图3中的实施例的描述一致,此处不做赘述。 In this step, a scheduler in the embodiment of FIG 3 is similar to, but also includes an uplink scheduling and downlink scheduling, wherein scheduling downlink consistent with the description of the embodiment in FIG. 3, is not repeated here. 下面仅描述上行调度: The following describes only the uplink scheduling:

[0085] 进行上行用户(包括CS用户和PS用户)的调度需要调度标志,如USF来完成。 [0085] for the uplink user (user including CS and PS user) scheduling needs schedule flags, such as USF accomplished. 在PS域仍延用现有技术中的上行状态标识(Uplink State Flag, USF)调度方式。 In the PS domain uplink state flag still continue to use the prior art (Uplink State Flag, USF) scheduling method. 在CS域, 需要在现有技术中的业务帧结构中増加USF域,即业务帧中插入USF域。 In the CS domain, a business needs a frame structure in the prior art to increase in the USF field, i.e. the traffic frames inserted in the USF field.

[0086]在高斯滤波最小移频键控(Gaussian Minimum Shift-frequency Keying, GMSK) 调制方式下,3位USF经编码之后形成12比持,因此在基于现有技术的编码之后的业务帧中需要有12比特的空间以插入USF,以便获得本发明实施例中的进行新的信道编码后的业务帧。 [0086] In Gaussian Minimum Shift Keying (Gaussian Minimum Shift-frequency Keying, GMSK) modulation scheme, after 3 USF 12 to hold encoded form, thus requiring service prior art frame after the encoding based there are 12 bits of space to insert USF, to obtain service frames for the new channel coding in the embodiment of the present invention.

[0087] 第一、可以将USF插入到进行编码之前的空闲比特(例如13k全速率,信道编码后有8比特空闲位)中。 [0087] First, the USF may be inserted into spare bits before encoding (e.g. 13k full rate, 8-bit idle channel coding bits) is.

[0088] 第二、可以对卷积码(是指ー种物理层的纠错编码技木)后的数据进行打孔,从而获得12比特的空间。 [0088] Second, a convolutional code can (refer ー seed physical layer error correction coding technology of wood) data punctured to obtain a 12-bit space. 全速率语音业务信道(Full rate Speech Traffic Channel, TCH FS) 业务帧中USF编码格式如图5所示。 Full rate speech traffic channels (Full rate Speech Traffic Channel, TCH FS) USF coded traffic frame format shown in FIG. 5.

[0089] 另外,USF只需要交织(交织是指重新对信号排序的过程)到当前的4个突发脉冲(burst)上去,并且交织的位置需要能够使PS用户侧能正确译码。 [0089] Further, only the USF interleaving (interleave process means re-ordered signal) to the current four bursts (Burst) up, and the position of the interleaved PS user side need to be able correctly decoded. 所以不管是PS数据块还是CS业务帧,USF在4个burst上的交织方式都是ー样的。 So regardless of CS or PS data service frame block, USF on four interleaved burst mode is ー like. 因此CS用户侧只需要按照CS域的方式进行解交织,然后从相应的位置读取出USF即可(这样USF可能穿插在前后两个业务帧内)。 Thus CS user side need only deinterleaving in the manner of the CS domain, and then read out from the position corresponding to USF (USF may be inserted in two such operations before and after the frame). 半速率语音业务的USF编码和全速率类似,这时需要将USF映射到两个半速率用户的业务帧内。 USF coding and half-rate voice services similar full rate, then the USF needs to be mapped to two frame half-rate traffic users.

[0090] 对于插入了USF后的业务帧,其上行调度的具体调度方式与图3的实施例中描述的方式一致,此处不做赘述。 [0090] For insertion of the USF service frames, specific embodiments thereof scheduling uplink scheduling FIG. 3 described in the same manner, is not repeated herein.

[0091] 在本发明实施例中的电路交換域业务的传输方法中还可进一歩包括用户侧对收到的业务进行区分的步骤,即用户侧对获得的所述在PS域传输所述CS域业务进行区分,获得CS或PS业务内容。 [0091] In the transmission circuit switched domain service method in the embodiment of the present invention may further comprise the step of the user into a ho-side receiving distinguish traffic, i.e. the user side is obtained in the CS PS domain transmission domain distinguish the business, get CS or PS business content.

[0092] 由于网络侧进行业务传输时,将CS/PS业务进行了复用,因此在用户侧需要用户终端可以区分上述两种业务,以便获得具体的业务内容。 [0092] Due to the network side transmission service, the CS / PS service is multiplexed with, so the user can distinguish the user terminal side needs to these two operations, so as to obtain the specific service content. 根据需要区分的对象的不同,对上述具体区分方式进行说明: The need to distinguish between the different objects, the above-described embodiment will be described with particular distinction:

[0093] DPS用户区分,即对不同的PS业务进行区分。 [0093] DPS user discrimination, i.e. different PS services distinguish.

[0094] 当CS和PS用户混合复用吋,PS用户之间的区分与现有技术中的相同,即由于PS 域业务都是经过RLC编解码的,因此还是通过RLC编码中的RLC/MAC头中的临时流标识(Temporary Flow Identity, TFI)来指示不同的PS 域业务。 [0094] When CS and PS user hybrid multiplexing the prior art to distinguish between inches, PS user is the same, i.e. are due to the PS domain service after the RLC codec, so it is encoded by the RLC RLC / MAC temporary flow identifier (temporary flow identity, TFI) header to indicate different PS domain service.

[0095] 2)CS/PS用户区分,即对CS业务和PS业务进行区分。 [0095] 2) CS / PS user discrimination, i.e., the CS service and the PS service distinguish.

[0096] 对于没有进行RLC编解码进行传输的CS域业务区分方式如下: [0096] For CS domain services no way to distinguish RLC transmission codec as follows:

[0097] 当PS业务的用户侧接收到CS业务帧吋,对该业务帧进行头译码时会出现校验不通过,因此对接收的数据进行头译码时出现校验不通过,则所述接收到的为CS业务,否则为PS业务。 [0097] occurs when the user verification is not through the receiving side PS service inch CS service frame, decode the traffic frame for the first time, so there does not pass verification when decoding the first received data, then the later received the CS business, otherwise PS business. 这种做法是和现有的支持PS业务的终端侧相兼容的。 This approach is the terminal side and the existing support PS service compatible.

[0098] 当CS用户进行CS业务和PS业务区分吋,可以通过业务内容中的偷帧比特来进行区分户。 [0098] When the user CS CS service and PS service differentiation inch, the user may be distinguished by a frame stealing bits of the service content. 在网络侧对每个业务帧或数据块经过编码和脉冲格式化后,有8个偷帧比特(即每个burst有2个偷帧比特),如在现有技术中,CS-I (Code Scheme-I编码方式_1,即GPRS的ー种RLC(L2)编码方式)为全l,CS-2 为(11001000),CS-3 为(00100001),CS-4 和MCS-1 〜 4为(00010110),TCH的偷帧比特为全0,快速随路控制信道(Fast Associated Control Channel,FACCH的偷帧比特为全1。因此在本发明实施例中,修改FACCH的偷帧比特为其他的比持,如为01010101,这样就可以通过偷帧比特区分CS和PS域业务。这是由干,PS域业务的偷帧比特为CS-I〜CS-4、MCS-I〜MCS-4的偷帧比特;TCH和FACCH的偷帧比特是CS 的偷帧比特;但是,CS-I和FACCH的偷帧比特相同,因此对其中一个进行修改后,就可以完全区分出CS用户和PS用户了;但为了不影响老的PS终端,所以需要修改FACCH的偷帧比持。 On the network side for each traffic frame or data block and encoded format through the pulse, there are eight stealing bit frames (i.e., each burst frame has two stealing bits), as in the prior art, CS-I (Code scheme-I encoding _1, i.e. the RLC GPRS ー species (L2) coding) for the whole l, CS-2 is (11001000), CS-3 is (00100001), CS-4 and MCS-1 ~ 4 is (00010110), TCH frame stealing bits of all 0, the fast associated control channel (fast Associated Control channel, FACCH frame stealing bits of 1. Therefore, in the whole of the embodiment of the present invention, the modified FACCH frame stealing bits other holding ratio, such as 01010101, which can be distinguished by the CS and the PS domain service stealing bit frames. this is a dry, the PS domain service frame stealing bits CS-I~CS-4, MCS-I~MCS-4 of stealing frame bit; stealing frame bit TCH and FACCH are CS steal frame bit; however, CS-I and the FACCH stealing frame bit the same, after therefore one modification, you can be completely distinguished CS user and PS user of ; but in order not to affect the old PS terminal, it is necessary to modify the FACCH frame stealing holding ratio.

[0099] 对于经过RLC编解码进行传输的CS域业务,可以根据语音业务中加入的TFI域进行区分。 [0099] CS domain service to be transmitted through the RLC codec, voice service can be differentiated according to the TFI field is added.

[0100] 3) CS用户区分,即对不同的CS业务进行区分。 [0100] 3) CS user discrimination, i.e. different CS services to distinguish.

[0101] 对于没有进行RLC编解码进行传输的CS域业务区分方式如下: [0101] For CS domain services no way to distinguish RLC transmission codec as follows:

[0102] 如果用户侧不支持CS用户复用于同一时隙,则不需要区分CS用户;否则需要实现CS用户之间的区分。 [0102] If the user side does not support CS for the same slots multiplexed user, the user is not required to distinguish between CS; otherwise need to achieve differentiation between the CS user. CS用户区分有3种方式: CS users to distinguish between three ways:

[0103] a、偷帧比持,如,可以定义一系列偷帧比特序列(8比持)来区分不同的CS用户。 [0103] a, than support frame stealing, e.g., define a series of bit sequences stealing frames (8 holding ratio) to distinguish between different users of CS.

[0104] b、训练序列,如,可以定义一系列相互正交的训练序列,来区分不同的CS用户。 [0104] b, the training sequence, e.g., define a series of mutually orthogonal training sequences to distinguish different users CS.

[0105] c、TFI,如,在业务帧中加入TFI域,来区分不同的CS用户。 [0105] c, TFI, e.g., added to the TFI field in the traffic frame, to distinguish between different CS users.

[0106] 其中,由于有可能对CS业务的数据进行CRC校验位,可以将TFI域与其中5位CRC 校验位进行异或,从而将TFI隐式携帯到接收端。 [0106] wherein, since it is possible for the CS service data CRC check bits may be 5 wherein the TFI field CRC check bit XOR, thereby implicitly carried Bands TFI to the reception side. 有些语音信道编码中会有ー些空闲比特(如13k全速率业务有4比特空闲位),也可以用来承载TFI。 Some voice channel coding will ー some spare bits (e.g., full-rate traffic 13k has 4-bit spare bit) can be used to carry TFI.

[0107] 但是当全速率和半速率语音业务复用同一时隙时,携带TFI的方法则无法区分。 [0107] However, when the full rate and half rate speech service multiplexing in the same time slot, the method is carried TFI indistinguishable. 此时同样可以采用训练序列或偷帧比特序列来区分全速率和半速率语音业务。 At this time, a training sequence or stealing frame bit sequences to distinguish between full rate and half rate speech service may also be employed.

[0108] 对于经过RLC编解码进行传输的CS域业务,可以根据语音业务中加入的TFI域进行区分。 [0108] CS domain service to be transmitted through the RLC codec, voice service can be differentiated according to the TFI field is added.

[0109] 同吋,在本发明实施例提供的方案中,对业务帧的加密,只需要在RLC/MAC层进行。 [0109] with the inch, the solution provided in embodiments of the present invention, the encrypted service frame, only in the RLC / MAC layer. 仍延用核心网下发的密钥,因此不会影响到核心网的正常流程。 Still continue to use the key sent by the core network, it will not affect the normal flow of the core network. 此处不做细述。 Not to dwell on here.

[0110] 通过上述对本发明实施例的描述可知,由于采用了复用的CS/PS业务,使得,信道资源的利用率得到了提高,如当采用GERAN承载CS业务吋,可使每时隙承载8个语音业务。 [0110] description of the embodiments of the present invention described above can be seen, the use of multiplexing CS / PS service, so, the channel resource utilization is improved, as when using GERAN CS bearer service inches per slot can carry 8 voice services. 同吋,电路和分组业务的复用,可以使网络承载更多的PS业务,或为PS业务分配更多的可用信道,从而提高了整体的网络容量和呑吐量;电路和分组域采用相同的Um ロL2协议,简化了网络结构,节约建网成本;并且真正实现了电路和分组域的资源共享,可以更加合理分配和充分利用有限的信道资源;同时利用GERAN的先进技术(如RTTI)可以提升电路业务的性能。 With the inch, the multiplexing circuit and packet services, allows the network to carry more PS service, or allocate more of the available channels as the PS service, thereby increasing the overall network capacity and throughput rate; circuit and packet domains using the same Um ro L2 protocol, simplifies the network structure, save the cost of network building; and realize resource sharing circuit and packet domain can be more rational distribution and full utilization of the limited channel resources; while using GERAN advanced technologies (e.g. RTTI) can enhance the performance of the circuit traffic.

[0117] 其中,调度模块2M可进ー步包括:设置子模块2240,用于设置向用户发送的CS 域业务的业务帧中的USF,所述USF用于指示可在下一上行块上传业务帧的用户,当CS域业务的用户根据接收的所述业务帧中的USF获知自己为可在下一上行块上传业务帧的用户吋,在下一上行块发送业务帧或SID帧;上行调度子模块2242,用于根据接收的用户发送的业务帧或SID帧进行上行调度,当收到SID帧后,表示该用户进入语音静默期,周期性调度该用户的上行传输SID帧或业务帧,并将空闲的上行资源分配给复用的CS或PS用户,当收到业务帧,表示该用户恢复到正常通话状态,这时需要时刻调度该用户的上行传输的业务帧。 [0117] wherein the scheduling module can enter ー 2M further comprising: a setting sub-module 2240, CS domain service traffic frame for transmission is provided to the user in the USF, the USF is used to indicate a next uplink block may upload traffic frames the user, when the user is informed of the CS domain service to their users can upload inch service frame in the next uplink block, frame or SID frame transmission service in the next uplink block according to the service frame received the USF; uplink scheduling sub-module 2242 for uplink scheduling according to the received traffic frame or SID frame sent by a user, when a SID frame is received, indicating that the user enters the voice silent period, periodically scheduled uplink transmission of the user traffic frames or SID frames, and idle the uplink resource allocation to a CS or PS user multiplexing, when the traffic frame is received, indicating that the user return to normal conversation state, then the time required scheduling service uplink transmission frames for that user.
