技术领域 FIELD

[0001] 本发明涉及重定向技术,尤其涉及一种重定向的方法及装置、终端、基站。 [0001] The present invention relates to a redirection, the redirection particularly to a method and an apparatus, a terminal, a base station.

背景技术 Background technique

[0002] 近些年飞速发展的移动宽带技术丰富了移动网承载的数据业务类型,促进了移动数据业务的增长;移动数据的快速增长,对移动接入又提出了新的带宽要求,二者相互影响,又相互促进。 [0002] In recent years, the rapid development of mobile broadband technology enriched mobile data network carrying business type, and promote the growth of mobile data services; rapid growth in mobile data, mobile access has raised new bandwidth requirements, both interaction, and promote each other. 移动网呈现出数据业务爆发、新技术制式层出的局面。 Mobile network data services showing outbreak situation out new technology standard layer. 为了进一步提高移动网接入速率,同时缓解频谱资源紧张的局面,国际标准组织第三代合作伙伴计划(3GPP, The 3rd Generation Partnership Project)加快了长期演进(LTE, Long TermEvolution)技术标准的制定。 To further enhance the mobile network access rate, and ease the tension of spectrum resources situation, ISO Third Generation Partnership Project (3GPP, The 3rd Generation Partnership Project) to speed up the long-term evolution (LTE, Long TermEvolution) technology standards. 同时,为了确保现有移动用户良好的业务感知体验,LTE标准在制定过程中,对现有系统间的互操作特性进行了大量研究,并作出了规定。 Meanwhile, in order to ensure that existing mobile users a good business sensory experiences, LTE standard in the development process, the interoperability features between the existing system a lot of research, and made provision.

[0003] 具体地,码分多址(CDMA, Code Division Multiple Access)网络的电路域Ix无线传输技术(RTT, Radio Transmission Technology)系统与分组域LTE网络的互操作是网络发展的一个趋势。 [0003] In particular, code division multiple access (CDMA, Code Division Multiple Access) circuit domain network Ix Radio Transmission Technology (RTT, Radio Transmission Technology) interoperable system and the LTE network packet domain network is a development trend. 一般来说,支持语音业务的CDMA Ix RTT网络作为广覆盖进行部署,图1为LTE网络及CDMA Ix RTT网络混合部署的结构示意图,如图1所示,LTE系统可以作为覆盖补盲或者提升容量而部署,不过CDMA Ix RTT网络也可以与LTE系统分别覆盖不同的地理位置。 In general, to support voice services CDMA Ix RTT as a wide coverage network deployment, FIG. 1 is a schematic structural diagram of an LTE network and CDMA Ix RTT network hybrid deployment, as shown, as an LTE system may increase the capacity to cover or fill blind 1 in FIG. deployed, CDMA Ix RTT network but the LTE system may be respectively cover different geographical locations.

[0004] 为了支持LTE/CDMA Ix RTT双模终端能够在语音业务来临时迅速从分组域LTE网络回退到CDMA Ix RTT网络,现有协议规定了两种方法:CSFB和e_CSFB。 [0004] In support of LTE / CDMA Ix RTT dual mode terminal capable of voice packet comes from the field quickly falls back to the LTE network CDMA Ix RTT network, existing protocol specifies two methods: CSFB and e_CSFB. 本专利只关注对CSFB技术的性能优化。 This patent only concerned with performance optimization of CSFB technology. 具体地,LTE系统和CDMAlx RTT网络之间通过交互解决方案(IWS,Interworking Solution)网元来建立透明的信令通道,LTE/CDMA双模终端通过该透明信令通道预先完成在CDMAlx RTT网络中的预注册。 Between particular, LTE systems, and to establish a transparent CDMAlx RTT network signaling channel by exchanging solutions (IWS, Interworking Solution) NE, LTE / CDMA dual mode terminal via the transparent signaling path is completed in advance CDMAlx RTT network pre-registration. 所述预注册过程是指终端在LTE的空口演进的通用陆地无线接入网(E-UTRAN, Evolved Universal Terrestrial Radio AccessNetwork)区域内将CDMA Ix RTT注册过程通过LTE-CDMA Ix RTT之间的隧道提前完成。 The pre-registration process in the terminal means universal terrestrial radio access network air interface of LTE evolved (E-UTRAN, Evolved Universal Terrestrial Radio AccessNetwork) within the area CDMA Ix RTT registration procedure through a tunnel between the LTE-CDMA Ix RTT advance carry out. 该预注册的相关空口流程主要包括:LTE eNB(基站)通过系统消息广播Ix网络信息,可以包括CDMA Ix网络识别(例如系统号和/或网络号)、频段、频点、邻区识别、功率控制参数(开环功率调整参数、功率调整步长)等;终端在发起CDMA Ix RTT预注册之前,先给eNB发送电路域业务回落(CSFB,Circuit Service FallBack)参数请求消息;eNB给终端发送CSFB参数响应消息,携带CDMA Ix RTT网络参数;eNB通过CDMA Ix RTT的IWS与CDMA Ix RTT之间建立S102隧道,终端通过该隧道完成CDMA Ix RTT注册。 The pre-registration of the relevant air interface procedure includes: LTE eNB (base station) through a system message broadcast Ix network information may include the CDMA Ix network identification (e.g., system number and / or network number), band, frequency, neighbor identification, power control parameters (open-loop power adjustment parameter, a power adjustment step size) and the like; terminal before initiating pre-registration CDMA Ix RTT, give eNB transmits circuit domain service drop (CSFB, circuit service FallBack) parameter request message; eNB sends to the terminal CSFB parameter response message carrying the CDMA Ix RTT network parameters; S102 tunnel established between the eNB via the IWS and CDMA Ix RTT CDMA Ix RTT, CDMA Ix RTT terminal completes registration through the tunnel.

[0005] 终端回退到CDMA Ix RTT电路域的典型流程包括:终端要发起一个语音呼叫;终端向移动性管理实体(MME, Mobility Management Entity)发送一个业务请求(CSFB指示语);MME向eNB发送终端上下文修改消息(终端能力、CSFB指示语),告知eNB将终端移至CDMA Ix RTT无线网络;在可选情况下,eNB向终端请求一个测量报告,检查目标CDMA IxRTT无线小区是否能完成CSFB ;eNB释放无线资源控制RRC (Radio Resource Control)连接;eNB通过SI接口向MME发送终端上下文释放请求(原因指示语为发生了CSFB到CDMAlxRTT网络);MME将终端上下文设为挂起状态,同时向服务网关(S-GW,Serving Gateway)发送挂起请求消息,要求终止终端的演进分组系统(EPS, Evolved Packet System)通道;S-Gff向MME回送响应消息,告知终端已经被挂起;E-UTRAN中关于该终端的上下文已经被释放;终端移到CDMA Ix RTT网络,按照正常步骤发起语音呼叫。 [0005] CDMA Ix RTT fallback terminal domain typical flow circuit comprising: a terminal to initiate a voice call; terminal sends a service request (CSFB instruction word) to the mobility management entity (MME, Mobility Management Entity); MME to eNB context modification message transmitting terminal (terminal capability, CSFB indication language), the terminal will notify the eNB CDMA Ix RTT move wireless network; in an alternative case, eNB a measurement report request to the terminal, to check whether the target cell can be completed wireless CDMA IxRTT CSFB ; the eNB releases the radio resource control RRC (radio resource control) connection; the eNB transmits to the MME via the interface SI terminal context release request (instruction word has occurred reason to CDMAlxRTT network CSFB); MME UE context to the suspend state, while the serving gateway (S-GW, serving gateway) transmits a suspend request message requesting termination terminal evolved packet system (EPS, evolved packet system) channel; S-Gff send back a response message to the MME to inform the terminals have been suspended; E- UTRAN context on the terminal has been released; terminal moves CDMA Ix RTT network, a voice call according to the normal procedure. 其中,在LTE的空中接口(eNB-终端)之间eNB是通过对终端触发重定向流程配合完成该流程的。 Wherein, between the LTE air interface (the eNB- terminal) by the eNB to trigger the terminal redirection process with the completion of the process. 所述重定向流程是指终端首先需要断开源通信系统(LTE系统)的无线通信,然后在目标通信系统的空闲状态下,搜索和驻留到目标通信系统的空闲状态下,搜索和驻留到目标通信系统的某个小区,最后在该小区内重新发起无线接入和业务请求过程。 The flow redirection means is a wireless communication terminal first to disconnect the source communication system (LTE system), and then in the idle state target communication system, search for and camp on the target communication system according to an idle state, to search and residing a communication system according to the target cell, and finally re-initiating wireless access service request processes within the cell.

[0006] 其中,LTE至CDMA Ix RTT无线连接重定向流程是指LTE网络在过载或者其他原因下,由LTE eNB主动发送RRC连接释放消息(RRCConnectionRelease Message)给终端,其中指定了要重新定向的载频信息,包括频段信息(bandclass)及绝对频点号(ARFCN,Absolute Radio Frequency Channel Number)。 [0006] wherein, LTE to CDMA Ix RTT wireless connection redirection process refers to the LTE network in the event of an overload or other reasons, sent by the LTE eNB active RRC Connection Release message (RRCConnectionRelease Message) to the terminal, which is specified to be reoriented carrier frequency information, including band information (bandclass) and absolute frequency number (ARFCN, absolute Radio frequency Channel number). 该流程避免了终端自行对可接入的网络进行盲检测,因此缩短了终端在系统间转换时的时延。 This process avoids the self-terminal to the network can access the blind detection, thus shortening the delay when switching between terminal system. 但是由于目前LTE协议支持eNB携带的辅助信息较少,因此LTE至CDMA Ix RTT重定向过程仍然非常缓慢,在现网中存在很大的时延。 However, due to the current LTE eNB protocol support less carry auxiliary information, so LTE to CDMA Ix RTT redirection process is still very slow, there is a big delay in the network now.

发明内容 SUMMARY

[0048]本不例中,重定向消息为 RRCConnectionRelease 消息,该RRCConnectionRelease消息中除了承载有重定向命令之外,还承载有从LTE系统重定向到CDMA Ix RTT网络的辅助信息。 [0048] In the present embodiment does not, as RRCConnectionRelease message redirection message, in addition to the message carries RRCConnectionRelease redirect command, but also carries the redirection information from the LTE system to the secondary network CDMA Ix RTT.

[0049] 本发明中,重定向的原因包括移动终端从LTE系统基站的覆盖区域进入到了CDMAIx RTT网络基站的覆盖区域,或者因为路径衰落等导致LTE系统基站的发射信号相当差而CDMA Ix RTT网络基站的发射信号较好等。 [0049] the present invention, the redirector comprises a mobile terminal enters the coverage area of ​​the LTE system base station to the coverage area of ​​CDMAIx RTT network base station, or because of fading as a result of a transmission signal LTE system base station rather poor and CDMA Ix RTT network the base station transmitted signal is preferably the like.

LTE系统基站基于该测量报告将终端重定向到合适的CDMA Ix RTT基站上。 LTE base station system based on the measurement report to the appropriate terminal redirected CDMA Ix RTT base station.

[0052] 其中,在LTE系统基站发送重定向命令之前或之后,如果终端在LTE系统的预注册区域,则可以由系统或者终端决定在CDMA Ix RTT网络上执行预注册。 [0052] wherein, before sending the redirect command the base station in an LTE system or after pre-registration if the terminal region of the LTE system, can be determined by the system or the terminal on the CDMA Ix RTT performs pre-registration network.

[0053] 本发明中,从LTE系统重定向到CDMA Ix RTT网络的辅助信息可以事先配置到LTE系统中如配置于基站侧或核心网侧,在确定对终端执行重定向时,由基站通过前述RRCConnectionRelease消息通知给终端。 [0053] In the present invention, the redirection information from the LTE system to the secondary network CDMA Ix RTT may be configured in advance to the LTE system as arranged on the side of the base station or the core network side, when the terminal determines to perform redirection, by the base station RRCConnectionRelease notification message to the terminal. 当然,从LTE系统重定向到CDMA Ix RTT网络的辅助信息也可以是由CDMA Ix RTT网络周期性或即时发送给LTE系统的。 Of course, the redirection information from the LTE system to the auxiliary CDMA Ix RTT network may be a CDMA Ix RTT network for real time or periodically sent to the LTE system. 例如,当邻区CDMAIx RTT网络的辅助信息发生了更新时,CDMA Ix RTT网络与LTE系统即进行交互,LTE系统获取并存储从LTE系统重定向到CDMA Ix RTT网络的辅助信息及时通知给终端。 For example, when the auxiliary information neighbor CDMAIx RTT of the network is updated, CDMA Ix RTT network and the LTE system interacts i.e., the LTE system acquires and stores the redirection information from the LTE system to the secondary network, CDMA Ix RTT notify the terminal. 例如,在从LTE系统重定向到CDMA Ix RTT网络的辅助信息更新时,CDMA Ix RTT网络将CDMA IxRTT网络的辅助信息通过CDMA Ix RTT网络与LTE系统之间的回程接口通知LTE系统。 For example, when redirecting from the LTE system to a CDMA Ix RTT network assistance information update, CDMA Ix RTT network assistance information CDMA IxRTT network via a backhaul interface to notify the LTE system, CDMA Ix RTT between the network and the LTE system. 回程接口为SlOl隧道、或为新定义的用于CDMAlx RTT网络与LTE系统之间交互的接口。 Backhaul interface SlOl tunnel, or a newly-defined interface interaction between CDMAlx RTT network for the LTE system.

[0054] 为了支持本实施例,RRCConncetionRelease消息中需要增加的承载信息如下: [0054] In order to support the present embodiment, RRCConncetionRelease need to increase the message carries the following information:
