Description

一种基于蜂窝高速分组接入网的小区切换方法 A high-speed packet-based cellular access network switching method of a cell

技术领域 FIELD

本发明涉及蜂窝高速分组接入(CHPA)系统中的小区切换方法。 The present invention relates to cellular High Speed ​​Packet Access (CHPA) system cell handover method.

背景技术 Background technique

在WCDMA系统中,用户设备(UE)在进行小区切换时,首先由通用陆地无线接入网(UTRAN)下发包含相邻小区具体的测量量(如路径损耗、接收信号功率等)和上报准则(如定时上报、超过或者低于某一门限上报)的测量控制消息给UE,同时UE测量本小区和相邻小区的信道质量,当本小区信道质量变差(低于UTRAN规定门限),相邻小区信道质量增强(超过UTRAN规定门限)时,UE通过测量上报消息向UTRAN上报测量结果,UTRAN根据测量结果决定是更新UE的激活集还是决定将UE切换到相邻异频小区,如果需要更新激活集,则UTRAN向UE发送激活集更新消息,UE接收到激活集更新消息并根据该消息增删相应激活集列表,同时转入新小区进而实现小区的软切换;如果需要切换到相邻异频小区,则UTRAN向UE发送重配置消息(如物理信道重配置消息),UE在接到UTRAN的激活集更新或者重配置消息后,重 In a WCDMA system, a user equipment (UE) performing cell switching, firstly by a universal terrestrial radio access network (UTRAN) comprising a specific issued cell measurements (e.g., path loss, received signal power, etc.) and adjacent reporting criteria (e.g., a timing report, exceeds or falls below a certain threshold reporting) the measurement control message to the UE, while the UE measures channel quality of the current cell and neighboring cell, this cell when a channel quality variation (UTRAN is below a predetermined threshold), the phase when the neighbor cell channel quality enhancement (exceeding UTRAN predetermined threshold), UE by a measurement report message reports the measurement result to the UTRAN, UTRAN decide to update the active set of the UE decided to handover the UE to the neighboring inter-frequency cells according to the measurement results, if necessary update active set, the UTRAN transmits to the UE activation set update message, the UE receives the active set update message and an active set list according to the corresponding additions to the message, while the soft handover into a cell so as to realize a new cell; if the inter-frequency HO to a neighboring cells, the UTRAN sends to the UE a reconfiguration message (e.g., a physical channel reconfiguration message), after receiving a UTRAN UE active set update message or a reconfiguration, a weight 新配置无线链路,并向UTRAN发送完成消息,进而完成整个小区切换过程。 The new radio link configuration, and sends a UTRAN complete message, thereby completing the whole-cell handover procedure.

在上述的UE小区切换过程中,需要UE完成小区信道质量的测量和测量结果的上报,这样将产生较多UE的电池消耗,同时UE是否进行小区切换由UTRAN决策判定,即由UTRAN的无线网络控制器(RNC)决策判定,然后通过UE重新配置实施切换,这样不但UE进行小区切换的时间较长,而且RNC的决策也非常复杂,导致了RNC复杂度和成本的增加。 In the UE during cell handover, the UE is required to complete the report and measurement results of channel quality cell channel, which will produce higher UE battery consumption, while the UE whether to perform cell handover determination by the UTRAN decision, i.e., by the UTRAN radio network controller (RNC) determines the decision, and then reconfigured to implement the handover UE, the UE will not only a longer time to switch the cell, but very complex decision-making of the RNC, RNC results in increased complexity and cost.

具体实施方式 Detailed ways

下面结合附图对本发明作进一步详细的描述。 DRAWINGS The invention is described in further detail below in conjunction.

首先参考图2,图2是应用图1所述方法的CHPA无线接入网结构图。 Referring first to FIG. 2, FIG. 2 is a configuration diagram of a radio access network CHPA the method of FIG. 1 is applied. 图2中,无线网络控制器(RNC-IP)为基于互联网协议(IP协议)的无线网络控制器,基站(WIB,Wireless Internet BaseStation)为基于互联网的基站,不同的RNC-IP通过接口Iur连接,RNC-IP与WIB通过接口Iub连接,WIB与UE之间通过接口Uu连接。 In FIG 2, a radio network controller (RNC-IP) based Internet Protocol (IP protocols) of the radio network controller, a base station (WIB, Wireless Internet BaseStation) to the base station based on the Internet, different RNC-IP connection via the interface Iur , RNC-IP through an interface Iub and WIB connected via the interface Uu between WIB and the UE. RNC-IP、WIB、与该WIB有连接的UE之间呈树状关系。 RNC-IP, WIB, there is the relationship between the tree was WIB UE connection.

在图2所示的网络中,为了更好地支持基于IP的移动UE,与第6版IP(IPv6)地址兼容,CHPA接入网中的RNC-IP、WIB和UE均设置128位(bit)的IP地址标识。 In the network shown in Figure 2, in order to better support the IP-based mobile UE, version 6 address is compatible with the IP (IPv6), CHPA then the RNC-IP network, and the UE WIB 128 are set (bit ) the IP address identifies. 其中RNC-IP和WIB为静态地址标识,由运营商在铺设网络时设定。 Where the RNC-IP to a static address and WIB logo, set by the operator at the time of laying the network. 在每一次WIB与UE建立会话时,WIB为UE动态分配一个临时标识UTI(UE Temporary Identifier),以便在该WIB内唯一标识UE以及与该UE之间的这一会话。 Each time UE establishes a session with WIB, WIB dynamically allocate a temporary identity UTI (UE Temporary Identifier) ​​is a UE, so that the session between the UE and the WIB uniquely identifies the UE. 在采用128bit的IP地址标识RNC-IP、WIB和UE时,将128bit的IP地址分为三段,前M1bit为第一段,用于标识RNC-IP;中部的M2bit为第二段,用于标识RNC-IP下的WIB,即用前M1bit加上M2bit标识RNC-IP下的WIB;后部的M3bit为第三段,用于标识WIB下的UE,即用前M1bit加上M2bit,再加上M3bit标识WIB下的UE。 When using 128bit IP address identifier RNC-IP, WIB and the UE, the IP address of 128bit divided into three sections, the first section of the front M1bit, for identifying RNC-IP; M2bit the middle of a second segment, for WIB in identifying RNC-IP, i.e., prior to use in M2bit WIB M1bit plus identification RNC-IP; M3bit rear portion of the third segment, the UE for identifying the WIB, i.e. before use M1bit M2bit plus, plus the UE under M3bit identity WIB. 在图2中,M1为80bit,M2为24bit,M3为24bit,参考图4。 In FIG. 2, M1 is a 80bit, M2 is a 24bit, M3 is a 24bit, with reference to FIG.

因此,在图2所示的网络中,一个WIB与一个IPv6子网一一对应。 Thus, in the network shown in FIG. 2, a WIB correspondence with a IPv6 subnet. 由于WIB与其分配UTI的UE处于同一子网,WIB与这些UE标识的前104位完全相同,WIB和这些UE共同构成一个WIB子系统。 Since the UE WIB its assigned UTI in the same subnet, WIB identical to those before the UE 104 identifier, and the UE WIB WIB constitute a subsystem. 而且相邻的WIB的前104位均不相同。 And 104 adjacent to the front WIB not the same. 另外,对于同一RNC-IP控制的WIB,其前80bit完全相同。 Further, for the same RNC-IP WIB control, front 80bit identical. 这些WIB以及由这些WIB分配UTI的UE,和该RNC-IP的标识前80bit均相同,它们共同构成一个RNC-IP子系统。 The WIB and WIB UTI by these allocation the UE, and the RNC-IP former 80bit identifier are the same, which together constitute a RNC-IP subsystem. 因此在图2中,不同的RNC-IP前80bit互不相同,并且前80bit相同的WIB属于同一RNC-IP控制。 Therefore, in FIG. 2, RNC-IP different mutually different front 80bit, 80bit same before and belonging to the same RNC-IP WIB control. 不同的WIB其前104bit互不相同,与同一个WIB建立连接的UE其UTI由这一WIB动态分配,并且这些UE的前104bit与这一WIB相同。 Different WIB front 104bit different from each other, to establish a connection with the UE which WIB UTI dynamically assigned by the WIB, and the UE is the same as before 104bit WIB.

基于图2,在图1所述的方法具体实施时,为了节省空中资源,避免在空中传输128bit的UTI,通过色码将WIB标识的前104bit,即用于区分WIB的前104bit压缩为8bit的色码,并且确定WIB标识到色码之间的映射关系,这种关系可以在运营商在建网之初设定,并将这一映射关系存放在每一个WIB中,即在每一WIB中存放色码与相邻WIB之间一、一对应的子网映射表,同时使WIB在广播的信息中包括自身的128bitIP地址标识W-ID以及色码。 Based on FIG. 2, the method of FIG 1 when a particular embodiment, the air in order to save resources, avoiding air transmission 128bit UTI by the front 104bit WIB color code identification, i.e. for distinguishing the front 104bit WIB compressed into the 8bit color code and determine WIB identity mapping relationships between color code, this relationship can be set at the beginning of operators in network construction and store the mapping in each WIB, that in each of the WIB storing a color code between WIB, corresponding to a subnet adjacent to the mapping table, including itself while WIB 128bitIP W-ID address mark and the color code in the information broadcast. 这样,只要任意相邻的WIB具有不同的色码,相同的色码可以在间隔一段距离后重用,不会出现一个色码对应两个相邻WIB的情况。 Thus, as long as any adjacent WIB having a different color code, the same color code may be reused after an interval of a distance, a case does not occur color code corresponding to the two adjacent WIB. 同时WIB根据色码即可得到唯一的一个相邻WIB标识的前104bit。 The WIB while the color code to obtain a unique identification of the adjacent front WIB 104bit.

基于上述操作,在UE与WIB建立连接后,相互之间的交互不必使用128bit的UTI,而是直接使用128bitIP地址标识的后24bit。 Based on the above operation, after establishing a connection with UE WIB, the interaction between each other without using the UTI 128bit, but directly after the address mark 128bitIP 24bit. 通过WIB广播自身的128bitIP地址标识W-ID以及色码,当UE移动进入另一WIB时,UE会检测到前104bit和色码与自身色码不同,由此UE知道已经进入另一个WIB,需要实施接力软切换过程。 WIB broadcast by itself 128bitIP W-ID address mark and a color code, when the UE moves into another WIB, 104bit UE detects the front and color code with its own different color code, whereby the UE knows WIB has entered another, need soft embodiment baton handover procedure.

图3描述WIB与色码之间的一种映射。 FIG 3 describes a mapping between WIB and the color code. 从图3可以看出,WIB8与WIB6使用相同的色码,即色码CC=6,由于他们之间相隔一段距离,因而WIB6的相邻WIB1可以通过色码将其区分开。 As it can be seen from FIG. 3, WIB8 WIB6 the same color code, i.e., color code CC = 6, since at a distance between them, so adjacent WIB1 WIB6 may be separated by color code region thereof.

图1是本发明所述方法的实施例流程图。 FIG 1 is a flowchart of a method embodiment of the present invention. 按照图1,初始时,UE与源WIB建立了一个连接并保持这一连接,并且源WIB为UE分配了一个128bit的临时UTI(UE临时标识),这样UE与源WIB之间交互通过UTI的后24bit即可。 According to FIG 1, initially, a source UE and a connection is established WIB and maintain this connection, the UE and the source WIB assigned a temporary 128bit of UTI (UE temporary identifier), so that through interaction between the UE and the source UTI the WIB after 24bit can be. UE移动过程中,在步骤1UE测量源WIB和相邻WIB的信道质量,信道质量的检测通过检测到源WIB、目标WIB的导频信号进行。 UE moves during the measurement at step 1UE source WIB WIB and adjacent channel quality, channel quality is detected by detecting the source WIB, WIB target pilot signal. 当相邻WIB的信道质量优于源WIB的信道质量时,UE将相邻的WIB作为目标WIB,读取该目标WIB的广播信息,从而获得目标WIB的W-ID和色码。 WIB when the adjacent channel quality is better than the channel quality of the source of the WIB, the UE as the target adjacent WIB WIB, WIB read the broadcast information of the target so as to obtain the target W-ID WIB and color code. 根据色码,此时UE知道进入新的WIB。 According to color code, then the UE knows to enter the new WIB. 然后UE在步骤2根据目标WIB广播的公共信道参数(物理随机接入信道/随机接入信道PRACH/RACH、快速物理接入信道FPACH、第二公共控制物理信道/前向接入信道SCCPCH/FACH)配置自身协议栈和物理层,并向目标WIB发起连接请求RADIO ACCESSREQUEST消息,该消息中携带了UE的原UTI,所述UTI包括用于区分WIB的色码和用于区分UE的比特位,即32位的原UTI(包含8位色码和最后的24比特位)。 The UE then at step channel parameters common channel (Physical Random Access Channel / Random Access Channel PRACH / RACH, Fast Physical Access Channel FPACH the target WIB broadcast 2, the second common control physical channel / forward access channel SCCPCH / FACH ) configures itself protocol stack and a physical layer, initiates a connection request to the target WIB RADIO ACCESSREQUEST message, and the message carries the UE's original UTI, UTI comprising a color code for distinguishing WIB bits for distinguishing the UE, i.e., the UTI 32 of the original (the 8-bit color code and the last 24 bits). 目标WIB通过对比UE原UTI中的前8位色码,发现与自身色码不同,即可知道该UE是从相邻WIB切换而来。 WIB by comparing the original target UE UTI in the previous 8-bit color code, color code different itself found, the UE can know from the adjacent switching from WIB.

目标WIB为了获取UE与源WIB的原有会话配置,在步骤3将UE的原UTI发送给自己对应的目标RNC-IP,由目标RNC-IP在步骤4获取UE的原有会话配置并发送给目标WIB,最后目标WIB在步骤5为UE分配新的UTI,所述UTI包括用于区分WIB的色码和用于区分UE的比特位;即目标WIB给UE分配新的32位UTI,前8bit为目标WIB自身色码,后24bit为当前UE在目标WIB内的唯一临时标识;同时,目标WIB为UE分配无线资源,建立新的通信链路并释放原有的通信链路,从而将UE与接入网之间的连接切换到新的WIB中。 WIB order to obtain certain UE is configured with the original source WIB's session, sent to their corresponding target RNC-IP UTI in the original step 3 of the UE, obtain the UE in step disposed concurrent original session by the target 4 to the RNC-IP WIB goal, the final objective WIB allocated for the UE in step 5 new UTI, UTI comprising a color code for distinguishing WIB bits for distinguishing the UE; i.e., assigned a new target WIB 32 UTI to the UE, before 8bit WIB color code as the goal itself, after the current 24bit unique temporary identity of the UE within the target WIB; at the same time, the target WIB allocate radio resources for the UE, establish a new communication link and releases the original communication link, and thus the UE the connection between the access network to switch to the new WIB.

本例中上述步骤3、4的实现参考如下过程:首先目标WIB根据UE原UTI中的前8位色码,以及根据自身的色码,子网映射表查找出源WIB标识比特位,即前104bit,与UTI后面用于标识UE的比特位,即UTI的后面24bit组合得到全部IP地址标识的原UE的UTI,即UE的128bit的原UTI。 In implementing the present embodiment described above with reference to the following process Steps 3 and 4: the first target source WIB WIB The UE identification bits in the original UTI color code the first 8 bits, and according to their color code lookup table mapping the subnet, i.e., before 104bit, and later for UTI bit identifier of the UE, i.e., the UTI 24bit composition obtained UTI behind all original IP address of the UE identifier, i.e. the UE 128bit original UTI. 此时根据WIB标识的前80bit,目标WIB可以判断出源WIB与自身同属于一个RNC-IP控制。 At this time, a front WIB 80bit identifier, can determine the source of the target WIB WIB itself belong to the same RNC-IP control. 接着目标WIB将128位的原UTI发给目标RNC-IP,请求查询该UE原有的会话配置(如L2配置、无线接入承载配置等)。 The target is then WIB 128 to targeted UTI original RNC-IP, the original request to query the UE's session configuration (e.g., L2 configuration, the radio access bearer configuration, etc.). 目标RNC-IP根据UTI的前80bit判断源WIB是否属于自己控制,如果属于自己控制,则根据前104bit,将UE的原UTI发往源WIB,请求源WIB反馈该UTI的会话配置信息。 The target RNC-IP 80bit front of UTI is determined whether the source WIB own control, if the control of their own, is a front 104bit, the UE will be sent to the original source of UTI WIB, the request source of the UTI WIB feedback session configuration information. 源WIB向目标RNC-IP返回该UE的原有会话配置,然后目标RNC-IP将这一会话配置发给目标WIB。 WIB return to the original source session configuration of the UE to the target RNC-IP, then this will be the target RNC-IP session configuration to targeted WIB. 如果源WIB不属于自己控制,则目标RNC-IP需要进一步明确源RNC-IP,根据UE原UTI的前80bit,目标RNC-IP将UE的原UTI发往源RNC-IP,源RNC-IP再将UE的原UTI转至源WIB,请求源WIB反馈该UTI的会话配置信息。 If the source WIB is not his own control, the target RNC-IP need to further clarify the source RNC-IP, sent to the source RNC-IP, source RNC-IP and then based on the original UTI UE former UTI before 80bit, target RNC-IP to the UE the original source WIB UTI go to the UE, the request source WIB feedback session configuration information of the UTI. 源WIB向源RNC-IP返回该UE的原有会话配置,源RNC-IP将UE的原有会话配置转交给目标RNC-IP,由目标RNC-IP将这一会话配置发给目标WIB。 WIB return to the original source session configuration of the UE to the source RNC-IP, the original source RNC-IP session UE configuration transferred to the target RNC-IP, by the target RNC-IP session configuration will be sent to this goal WIB.

本例中上述步骤5所述目标WIB为UE分配无线资源,建立新的通信链路并释放原有的通信链路的实现参考如下过程:当源WIB和目标WIB属于同一个RNC-IP控制时,目标WIB为UE分配无线资源,建立无线链路,同时目标WIB与RNC-IP之间建立地面链路,释放RNC-IP与源WIB之间的地面链路资源以及释放源WIB与UE之间的空中链路资源。 In the present embodiment the above step 5 WIB target UE is allocated radio resources and establish a new communication link release the original communication link is implemented with reference to the following procedure: when the source and destination WIB WIB belong to the same RNC-IP Control between, UE allocate radio resources to establish a radio link, while establishing a link between ground targets WIB and RNC-IP, terrestrial link the release of resources between RNC-IP and source WIB and WIB release source and target UE for the WIB the air link resources.

当源WIB和目标WIB不属于同一个RNC-IP控制时,目标WIB为UE分配无线资源,建立无线链路,目标WIB与RNC-IP之间建立地面链路以及目标RNC-IP与SGSN之间建立链路;同时释放RNC-IP与SGSN之间链路、释放RNC-IP与源WIB之间的地面链路资源,以及释放源WIB与UE之间的空中链路资源。 When the source and destination WIB WIB not belong to the same RNC-IP control, terrestrial link between the target and the target WIB RNC-IP and the SGSN allocates radio resources is a UE, to establish a radio link established between the target RNC-IP and WIB establish the link; while releasing the link between the RNC-IP and SGSN, releasing resources terrestrial links between RNC-IP and source WIB, and air link resources between the release of the source WIB and the UE.
