本发明实施例涉及通信技术领域， 特别涉及一种切换处理的方 法、 系统和装置。 背景技术  The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, system, and apparatus for handover processing. Background technique
为了满足日益增长的无线业务的增长， 在现有的单载波 CDMA ( Code Division Multiple Access, 码分多址）通信系统基础上提出了 多载波 CDMA通信系统。多载波通信系统可以同时在两个或更多个载 频上传输数据，对一个用户来说它的上行链路和下行链路可以同时使 用相同或不同个数的载频进行通信。  In order to meet the growing wireless service growth, a multi-carrier CDMA communication system is proposed based on the existing single-carrier CDMA (Code Division Multiple Access) communication system. A multi-carrier communication system can simultaneously transmit data on two or more carrier frequencies, and for one user, its uplink and downlink can simultaneously communicate using the same or a different number of carrier frequencies.
在多载波 CDMA通信系统中， 可能存在以下组网场景：  In a multi-carrier CDMA communication system, the following networking scenarios may exist:

( 2 )上、 下行配置两个成对载频， 这两个载频属于同一频段。 (2) Two pairs of carrier frequencies are configured in the uplink and downlink, and the two carrier frequencies belong to the same frequency band.
( 3 )上、 下行配置两个成对载频， 这两个载频一个属于 900M频 段、 一个属于 2G频段。 其中 900M频段可用于连续覆盖， 2G频段用于 小区中心的容量提升。 (3) Two pairs of carrier frequencies are configured in the uplink and downlink. The two carrier frequencies belong to the 900M frequency band and one belongs to the 2G frequency band. Among them, the 900M frequency band can be used for continuous coverage, and the 2G frequency band is used for capacity improvement of the cell center.
( 4 ) 下行采用 K1/K3频率复用方式组网。 也就是说下行同时使 用两个频点， 其中一个频点对所有扇区都是相同的， 另一个频点对 3 个扇区是不同的 （采用 K3复用方式） ， 从而减小小区间的干扰。 在这些复杂的组网场景下，都需要解决用户移动时的小区间切换 问题。 对 HSPA ( High Speed Packet Access, 高速分组接入）用户， 还需要根据各个载频的信号质量更新用户的服务小区。 (4) The downlink uses K1/K3 frequency reuse mode networking. That is to say, the downlink uses two frequency points at the same time, one frequency point is the same for all sectors, and the other frequency point is different for three sectors (using K3 multiplexing mode), thereby reducing inter-cell interference. In these complex networking scenarios, it is necessary to solve the problem of inter-cell handover when the user moves. For HSPA (High Speed Packet Access) users, it is also necessary to update the user's serving cell according to the signal quality of each carrier frequency.

本发明实施例提供一种切换处理的方法，用于在多载波通信系统 中进行小区间切换。  Embodiments of the present invention provide a handover processing method for performing inter-cell handover in a multi-carrier communication system.
本发明实施例引入多载波小区的概念：一个多载波小区可以支持 多个载频， 这些载频对应的小区在地理位置上会有一定的相关性。 在 本发明实施例中，多载波小区指不同于原来的单载波小区的一种特殊 小区， 该小区有自己的小区 ID ( Identifier, 标识符）， 支持多个载频； 或者， 多载波小区指一个小区集合， 该小区集合中的每个小区都和现 有技术中的单载波小区一样是独立的小区，该小区集合中的每个小区 的小区 ID可以相同， 也可以不同。  The embodiment of the present invention introduces the concept of a multi-carrier cell: a multi-carrier cell can support multiple carrier frequencies, and the cells corresponding to these carrier frequencies have a certain correlation in geographic location. In the embodiment of the present invention, the multi-carrier cell refers to a special cell different from the original single-carrier cell, and the cell has its own cell ID (Identifier), which supports multiple carrier frequencies; or, multi-carrier cell refers to A cell set, each cell in the cell set is an independent cell like the single-carrier cell in the prior art, and the cell ID of each cell in the cell set may be the same or different.
本发明实施例进一步引入主载频的概念：在多载波小区中选择一 个载频作为主载频， 例如： 如果上行或下行使用一个载频时， 则可以 以该载频作为主载频； 如果上、 下行有业务承载在 DCH ( Dedicated Channel, 专用信道）上， 则可以以 DCH所在载频作为主载频； 如果 上、下行都同时使用了多个载频且不存在承载在 DCH上的业务， 则可 以由网络侧根据 UE上报的 2a事件， 决定主载频的变更， 其中 2a事件 指信号质量最好的载频发生了改变。 每次主载频改变后， 网络侧下发 新的测量控制消息告知 UE用于切换测量的载频。 UE根据主载频决定各种测量事件的触发， 但上报测量报告时需 要携带所有载频的信息， 网络侧在决定是否将小区加入激活集时， 特 别是 Id事件触发时， 可以综合考虑所有载频的信号质量， 其中 Id事件 指信号质量最好的同频小区发生了改变。 The embodiment of the present invention further introduces the concept of a primary carrier frequency: selecting a carrier frequency as a primary carrier frequency in a multi-carrier cell, for example, if a carrier frequency is used for uplink or downlink, the carrier frequency can be used as a primary carrier frequency; If the uplink and downlink services are carried on the DCH (Dedicated Channel), the carrier frequency of the DCH can be used as the primary carrier frequency. If both the uplink and the downlink use multiple carrier frequencies and there is no service carried on the DCH. Then, the network side may determine the change of the primary carrier frequency according to the 2a event reported by the UE, where the 2a event refers to the carrier frequency with the best signal quality being changed. After each change of the primary carrier frequency, the network side sends a new measurement control message to inform the UE to switch the measured carrier frequency. The UE determines the triggering of various measurement events according to the primary carrier frequency, but needs to carry all the carrier frequency information when reporting the measurement report. When the network side decides whether to add the cell to the active set, especially when the Id event is triggered, all the carriers can be comprehensively considered. Frequency signal quality, where the Id event refers to a change in the same frequency cell with the best signal quality.
如图 1所示， 为本发明实施例一中提供的切换处理的方法的流程 图， 可以包括：  As shown in FIG. 1, the flowchart of the method for switching processing provided in the first embodiment of the present invention may include:
5101 , 通过测量控制消息通知 UE在选择的主载频上进行测量， 该主载频是在多载波小区中选择的。  5101. The UE is notified by the measurement control message to perform measurement on the selected primary carrier frequency, where the primary carrier frequency is selected in the multi-carrier cell.
主载频的选择过程可以为：  The selection process of the main carrier frequency can be:
当 UE的上行或下行链路只使用一个载频时， 选择该使用的载频 为主载频； 或者，  When the uplink or downlink of the UE uses only one carrier frequency, the carrier frequency used is selected as the primary carrier frequency; or
当 UE的上行或下行链路上存在承载在 DCH上的业务时， 选择 DCH所在的载频为主载频； 或者，  When there is a service carried on the DCH on the uplink or downlink of the UE, the carrier frequency where the DCH is located is selected as the primary carrier frequency; or
当 UE的上行和下行链路同时使用多个载频且不存在承载在 DCH 上的业务时， 选择多个载频中信号质量最好的载频为主载频， 多个载 频中除主载频之外的载频为辅载频， 且网络侧根据 UE上报的 2a事件， 决定主载频的变更。  When the uplink and downlink of the UE use multiple carrier frequencies at the same time and there is no service carried on the DCH, the carrier frequency with the best signal quality among the multiple carrier frequencies is selected as the primary carrier frequency, and the carrier frequency is divided into multiple carriers. The carrier frequency other than the carrier frequency is the secondary carrier frequency, and the network side determines the change of the primary carrier frequency according to the 2a event reported by the UE.
网络侧通过测量控制消息通知 UE在主载频和辅载频上进行测 量， UE上报的测量报告包括但不限于主载频和辅载频的信号质量。  The network side notifies the UE to measure on the primary carrier frequency and the secondary carrier frequency by using the measurement control message, and the measurement report reported by the UE includes but is not limited to the signal quality of the primary carrier frequency and the secondary carrier frequency.
5102, 接收 UE上报的测量报告， 根据该测量报告维护激活集， 并更新 UE的服务小区。  S102: Receive a measurement report reported by the UE, maintain an activation set according to the measurement report, and update a serving cell of the UE.
通过 S 102 , 可以使 UE可以在多载波系统中进行小区间切换处理。 根据测量报告维护激活集可以为：  Through S 102 , the UE can be made to perform inter-cell handover processing in the multi-carrier system. Maintaining an activation set based on a measurement report can be:
当 UE的上行和下行链路同时使用多个载频时， 维护主载频和辅 载频的激活集， 使辅载频的激活集是主载频的激活集的子集， 主载频 的服务小区和辅载频的服务小区保持一致。 具体为： 主载频和辅载频 的服务小区是同一个小区， 或者， 主载频和辅载频的服务小区属于同 一个多载波小区。  When the uplink and downlink of the UE use multiple carrier frequencies simultaneously, the active set of the primary carrier frequency and the secondary carrier frequency are maintained, so that the active set of the secondary carrier frequency is a subset of the active set of the primary carrier frequency, and the primary carrier frequency The serving cell and the serving cell with the secondary carrier frequency are consistent. Specifically, the serving cell of the primary carrier frequency and the secondary carrier frequency is the same cell, or the primary carrier frequency and the secondary carrier frequency serving cell belong to the same multi-carrier cell.
其中， 维护主载频的激活集可以为： 网络侧根据 UE上报的 lx事件决定是否将一个小区加入主载频的 激活集， 或者是否将一个小区从主载频的激活集中删除。 上述小区可 以为一个多载波小区，也可以为一个多载波小区集合中使用主载频的 单载波小区。其中， lx事件是协议规定的一类同频测量事件， 包括 la、 lb或 lc事件等， la事件指一个不在激活集中的小区的信号质量已经变 得比较好， 高于上 范围， 例如它和激活集中的最好小区相比， 信号 质量的差值小于预定的门限， 网络侧收到 UE上报的 la事件后会把这 个小区加入主载频的激活集； lb事件指激活集中某个小区的质量变得 较差， 网络侧收到 UE上报的 lb事件后会删除和这个小区建立的连接， 即网络侧将该小区从主载频的激活集中删除； lc事件指激活集外的一 个小区的信号质量高于激活集内的最差小区的信号质量，网络侧收到 lc事件后会用这个小区替换主载频的激活集内的最差小区。 The active set for maintaining the primary carrier frequency can be: The network side determines whether to add a cell to the active set of the primary carrier frequency according to the lx event reported by the UE, or whether to delete a cell from the active set of the primary carrier frequency. The above cell may be a multi-carrier cell, or may be a single-carrier cell using a primary carrier frequency in a multi-carrier cell set. The lx event is a type of intra-frequency measurement event specified by the protocol, including la, lb or lc events. The la event refers to a signal quality of a cell that is not in the active set has become better, higher than the upper range, for example, and Compared with the best cell in the active set, the difference in signal quality is less than a predetermined threshold, and the network side adds the cell to the active set of the primary carrier frequency after receiving the la event reported by the UE; The quality becomes poor. The network side deletes the connection established with the cell after receiving the lb event reported by the UE, that is, the network side deletes the cell from the active set of the primary carrier frequency; the lc event refers to a cell outside the active set. The signal quality is higher than the signal quality of the worst cell in the active set. After receiving the lc event, the network side replaces the worst cell in the active set of the primary carrier frequency with this cell.
此外， 维护辅载频的激活集可以为：  In addition, the active set that maintains the secondary carrier frequency can be:
当 UE上报的测量报告中指示多载波小区的辅载频信号质量高于 预定门限时， 将该多载波小区加入辅载频的激活集；  When the quality of the secondary carrier frequency signal of the multi-carrier cell is higher than the predetermined threshold in the measurement report reported by the UE, the multi-carrier cell is added to the active set of the secondary carrier frequency;
当 UE上报的测量报告中指示该多载波小区的辅载频信号质量低 于预定门限时， 将该多载波小区从辅载频的激活集中删除；  When the measurement report reported by the UE indicates that the quality of the secondary carrier frequency signal of the multi-carrier cell is lower than a predetermined threshold, the multi-carrier cell is deleted from the active set of the secondary carrier frequency;
维护辅载频的激活集还可以为：  The active set that maintains the secondary carrier frequency can also be:
当 UE上报的测量报告中指示多载波小区集合中使用辅载频的小 区的信号质量高于预定门限时，将该使用辅载频的小区加入辅载频的 激活集；  When the signal quality of the cell using the secondary carrier frequency in the multi-carrier cell set is higher than the predetermined threshold in the measurement report reported by the UE, the cell using the secondary carrier frequency is added to the active set of the secondary carrier frequency;
当 UE上报的测量报告中指示该多载波小区集合中使用辅载频的 小区的信号质量低于预定门限时，将该使用辅载频的小区从辅载频的 激活集中删除。  When the measurement report reported by the UE indicates that the signal quality of the cell using the secondary carrier frequency in the multi-carrier cell set is lower than a predetermined threshold, the cell using the secondary carrier frequency is deleted from the active carrier of the secondary carrier frequency.
另外， 根据测量报告维护激活集还可以为：  In addition, maintaining the activation set based on the measurement report can also be:
根据测量报告维护主载频和辅载频的激活集，使该辅载频的服务 小区与主载频的激活集中信号质量最好的小区保持一致。如果主载频 的激活集中信号质量最好的小区发生改变且信号质量最好的小区不 在辅载频的激活集中，则将主载频信号质量最好的小区对应的辅载频 小区加入辅载频的激活集，并以该主载频信号质量最好的小区对应的 辅载频作为辅载频的服务小区。 The active set of the primary carrier frequency and the secondary carrier frequency is maintained according to the measurement report, so that the serving cell of the secondary carrier frequency is consistent with the cell with the best active signal quality of the primary carrier frequency. If the cell with the best signal quality in the active carrier of the primary carrier frequency changes and the cell with the best signal quality is not in the active set of the secondary carrier frequency, the secondary carrier frequency corresponding to the cell with the best quality of the primary carrier frequency signal is used. The cell joins the active set of the secondary carrier frequency, and uses the secondary carrier frequency corresponding to the cell with the best quality of the primary carrier frequency signal as the serving cell of the secondary carrier frequency.
另外，本发明实施例还可以根据测量报告上报的主载频和辅载频 的信号质量， 以及主载频和辅载频的信号质量最好的小区的负载情 况， 更新 UE的服务小区。  In addition, the embodiment of the present invention may further update the serving cell of the UE according to the signal quality of the primary carrier frequency and the secondary carrier frequency reported by the measurement report, and the load condition of the cell with the best signal quality of the primary carrier frequency and the secondary carrier frequency.
另外，本发明实施例还可以根据测量报告上报的主载频和辅载频 的信号质量， 维护主载频和辅载频的激活集以及 务小区， 这时主载 频和辅载频的服务小区也可以不一致。  In addition, the embodiment of the present invention can also maintain the active set of the primary carrier frequency and the secondary carrier frequency and the service cell according to the signal quality of the primary carrier frequency and the secondary carrier frequency reported by the measurement report, and the services of the primary carrier frequency and the secondary carrier frequency. The cells can also be inconsistent.
本发明实施例提出的切换处理的方法适用于 UE的上行或下行链 路使用一个或多个载频的场景， 但本发明实施例以 UE的上行或下行 链路使用一个或两个载频为例进行说明。下面结合多载波通信系统的 几种不同的组网场景， 对本发明实施例作进一步详细描述：  The method for the handover process in the embodiment of the present invention is applicable to a scenario in which one or more carrier frequencies are used in the uplink or downlink of the UE, but the embodiment of the present invention uses one or two carrier frequencies in the uplink or downlink of the UE. The example is explained. The embodiments of the present invention are further described in detail below in combination with several different networking scenarios of the multi-carrier communication system:
一、 当上、 下行配置一个成对载频 fl , 下行额外配置一个不成对 的下行载频 f2时，  1. When a pair of carrier frequency fl is configured for uplink and downlink, and an unpaired downlink carrier frequency f2 is additionally configured for downlink,
选择成对载频 fl作为主载频。 网络侧在下发的测量控制消息中指 示 UE根据 fl的信号质量来决定测量事件的触发和上报， 网络侧收到 UE的测量报告后可以根据 UE在载频 f 1上的测量结果进行激活集的维 护。  The paired carrier frequency fl is selected as the primary carrier frequency. The network side in the measurement control message that is sent by the network indicates that the UE determines the triggering and reporting of the measurement event according to the signal quality of the fl. After receiving the measurement report of the UE, the network side may perform the activation set according to the measurement result of the UE on the carrier frequency f 1 . maintain.
在这种场景下，UE根据辅载频的信号质量决定是否与载频 f2建立 连接。其中， UE与载频 f2建立连接可以为： UE在载频 f2上只和 HSDPA ( High Speed Downlink Packet Access, 高速下行分组接入 )服务小区 建立连接。  In this scenario, the UE determines whether to establish a connection with the carrier frequency f2 according to the signal quality of the secondary carrier frequency. The UE may establish a connection with the carrier frequency f2. The UE may only establish a connection with the HSDPA (High Speed Downlink Packet Access) serving cell on the carrier frequency f2.
当 UE上报的测量报告中指示多载波小区的载频 f2的信号质量高 于预定门限时， 将该多载波小区加入辅载频的激活集；  When the signal quality of the carrier frequency f2 of the multi-carrier cell is higher than the predetermined threshold in the measurement report reported by the UE, the multi-carrier cell is added to the active set of the secondary carrier frequency;
当 UE上报的测量报告中指示该多载波小区的载频 f2的信号质量 低于预定门限时， 将该多载波小区从辅载频的激活集中删除。 或者， 当 UE上报的测量报告中指示多载波小区集合中使用 f2的小区的 信号质量高于预定门限时， 将该使用 f2的小区加入辅载频的激活集； 当 UE上报的测量报告中指示该多载波小区集合中使用 f 2的小区 的信号质量低于预定门限时， 将该使用 f2的小区从辅载频的激活集中 删除； When the signal quality of the carrier frequency f2 of the multi-carrier cell is lower than the predetermined threshold in the measurement report reported by the UE, the multi-carrier cell is deleted from the active set of the secondary carrier frequency. Or, when the signal quality of the cell using the f2 in the multi-carrier cell set is higher than the predetermined threshold, the cell using the f2 is added to the active set of the secondary carrier frequency; when the measurement report reported by the UE indicates a cell using f 2 in the multi-carrier cell set When the signal quality is lower than the predetermined threshold, the cell using f2 is deleted from the active set of the secondary carrier frequency;
二、 当网络上、 下行同时配置了两个成对的载频时，  2. When two pairs of carrier frequencies are configured on the network and downlink,
UE根据业务承载在 R99还是 HSPA上决定上、 下行链路具体使用 几个载频， 因此 UE的上、 下行链路可能都使用两个载频， 也可能只 有上行或只有下行使用两个载频。  The UE determines whether the uplink and downlink use several carrier frequencies according to the service bearer on the R99 or the HSPA. Therefore, the uplink and downlink of the UE may use two carrier frequencies, and only two uplink or only downlink carriers may be used. .
当上、 下行链路同时使用了两个载频时， 如果上、 下行都没有业 务承载在 DCH上， 则网络侧会发送测量控制消息要求 UE根据使用的 两个载频的信号质量上报 2a事件， 然后网络侧根据 2a事件决定主载频 的变更， 以最好载频作为主载频。 如果上行或下行链路有业务承载在 DCH上， 则以 DCH所在载频为主载频。  When the uplink and downlink use two carrier frequencies at the same time, if no traffic is carried on the DCH, the network side sends a measurement control message requesting the UE to report the 2a event according to the signal quality of the two carrier frequencies used. Then, the network side determines the change of the main carrier frequency according to the 2a event, and uses the best carrier frequency as the main carrier frequency. If the uplink or downlink has traffic carried on the DCH, the carrier frequency of the DCH is the primary carrier frequency.
当上行或下行链路由于业务承载类型的原因当前只使用了一个 载频时， 则以该使用的载频作为主载频。 当业务承载类型改变后可以 同时使用两个载频时， 网络侧下发测量控制消息要求 UE测量当前未 使用的载频判断是否满足 2c事件的触发条件， 如果满足， 则将这个载 频上的小区加入激活集。  When the uplink or downlink currently uses only one carrier frequency due to the type of service bearer, the carrier frequency used is used as the primary carrier frequency. When two carrier frequencies can be used simultaneously when the service bearer type is changed, the network side sends a measurement control message requesting the UE to measure whether the currently unused carrier frequency determines whether the trigger condition of the 2c event is met, and if it is satisfied, the carrier frequency is The cell joins the active set.
当上行或下行链路支持使用两个载频，但由于信号质量原因当前 只使用了一个载频时， 则以当前使用的载频作为主载频。 当前没使用 的载频上的小区可以通过 2c事件的触发被加入激活集， 加入后， 网络 侧根据两个载频的信号质量决定主载频是否需要改变。  When the uplink or downlink supports the use of two carrier frequencies, but only one carrier frequency is currently used for signal quality reasons, the currently used carrier frequency is used as the primary carrier frequency. The cell on the currently unused carrier frequency can be added to the active set by the trigger of the 2c event. After joining, the network side determines whether the primary carrier frequency needs to be changed according to the signal quality of the two carrier frequencies.
每次主载频改变后， 网络侧下发新的测量控制消息告知 UE用于 小区间同频、 异频或异系统切换测量的载频。  After each change of the primary carrier frequency, the network side sends a new measurement control message to inform the UE of the carrier frequency used for the small-band co-frequency, inter-frequency or inter-system handover measurement.
网络侧可以分别维护主载频和辅载频的激活集， 例如：  The network side can maintain the active set of the primary carrier frequency and the secondary carrier frequency separately, for example:
( 1 )只有当 UE可以同时使用两个载频时， 才维护辅载频的激活 集。  (1) The active set of the secondary carrier frequency is maintained only when the UE can use two carrier frequencies simultaneously.
( 2 )由于 DCH只会承载在主载频上， 因此辅载频只需要对 HSPA 业务维护激活集。 也就是说， 如果上行有 HSUPA业务， 网络侧需要 对辅载频维护 E-DCH ( Enhanced Dedicated Channel, 增强专用信道） 激活集； 如果上行没有 HSUPA业务， 网络侧只需要对辅载频维护 HSDPA服务小区。 (2) Since the DCH is only carried on the primary carrier frequency, the secondary carrier frequency only needs to maintain the active set for the HSPA service. That is, if there is an HSUPA service on the uplink, the network side needs to maintain the E-DCH (Enhanced Dedicated Channel) activation set for the secondary carrier frequency. If the uplink does not have the HSUPA service, the network side only needs to maintain the secondary carrier frequency. HSDPA service cell.
( 3 ) 当 UE和两个载频都建立连接时， 保证两个载频的服务小区 一致。  (3) When the UE and the two carrier frequencies are connected, the serving cells of the two carrier frequencies are guaranteed to be the same.
( 4 )辅载频的激活集是主载频激活集的子集。 也就是说， UE上 报信号质量变化时， 需要同时上报多载波小区内两个载频的信号质 量。 只有当主载频上的多载波小区被加入激活集时， 辅载频上的多载 波小区才会被加入激活集； 当主载频上的多载波小区被从激活集中删 除时， 辅载频上的多载波小区也要被从激活集中删除。 或者，  (4) The active set of the secondary carrier frequency is a subset of the primary carrier frequency active set. That is to say, when the UE reports a signal quality change, it is required to simultaneously report the signal quality of the two carrier frequencies in the multi-carrier cell. Only when the multi-carrier cell on the primary carrier frequency is added to the active set, the multi-carrier cell on the secondary carrier frequency is added to the active set; when the multi-carrier cell on the primary carrier frequency is deleted from the active set, the secondary carrier frequency Multi-carrier cells are also removed from the active set. Or,
当主载频上的小区加入激活集时，才考虑将该小区所在的多载波 小区集合中使用辅载频的小区加入激活集。 当主载频上的小区被从激 活集中删除时，该小区所在的多载波小区集合中使用辅载频的小区也 要从激活集中删除。  When the cell on the primary carrier frequency is added to the active set, the cell using the secondary carrier frequency in the set of multi-carrier cells in which the cell is located is considered to be added to the active set. When the cell on the primary carrier frequency is deleted from the active set, the cell using the secondary carrier frequency in the set of multi-carrier cells in which the cell is located is also deleted from the active set.
( 5 )在把使用辅载频的小区加入辅载频的激活集时， 该小区的 信号质量还需要高于预设的门限； 当使用辅载频的某个小区的信号质 量低于预设的门限时， 需要将 UE与这个小区在辅载频上建立的连接 删除；  (5) When the cell using the secondary carrier frequency is added to the active set of the secondary carrier frequency, the signal quality of the cell needs to be higher than the preset threshold; when the signal quality of a cell using the secondary carrier frequency is lower than the preset At the threshold, the connection established between the UE and the cell on the secondary carrier frequency needs to be deleted;
对主载频， UE上报 lx事件供网络侧决定是否将一个小区加入主 载频的激活集， 或者是否将一个小区从主载频的激活集中删除。 上述 小区可以为一个多载波小区，也可以为一个多载波小区集合中使用主 载频的单载波小区。 其中， lx事件是协议规定的一类同频测量事件， 包括 la、 lb或 lc事件等， la事件指一个不在激活集中的小区的信号 质量已经变得比较好， 高于上 范围， 例如它和激活集中的最好小区 相比， 信号质量的差值小于一个门限， 网络侧收到 UE上报的 la事件 后会^ 这个小区加入激活集； lb事件指激活集中某个小区的质量变得 较差， 网络侧收到 UE上报的 lb事件后会删除和这个小区建立的连接； lc事件指激活集外的一个小区的信号质量高于激活集内的最差小区 的信号质量， 网络侧收到 lc事件后会用这个小区替换激活集内的最差 小区。  For the primary carrier frequency, the UE reports an lx event for the network side to decide whether to add a cell to the active set of the primary carrier frequency, or whether to delete a cell from the active set of the primary carrier frequency. The above cell may be a multi-carrier cell or a single-carrier cell using a primary carrier frequency in a multi-carrier cell set. The lx event is a type of intra-frequency measurement event specified by the protocol, including la, lb or lc events. The la event refers to a signal quality of a cell that is not in the active set has become better, higher than the upper range, for example, and Compared with the best cell in the active set, the difference in signal quality is less than a threshold. After the network side receives the la event reported by the UE, the cell joins the active set. The lb event indicates that the quality of a cell in the active set becomes poor. After receiving the lb event reported by the UE, the network side deletes the connection established with the cell; the lc event indicates that the signal quality of one cell outside the active set is higher than the signal quality of the worst cell in the active set, and the network side receives the lc. This cell is used to replace the worst cell in the active set after the event.
对辅载频， UE要上报测量报告， 网络侧在主载频激活集子集的 范围内根据上报的事件决定 UE和辅载频小区的连接的建立和删除。 具体可以为： For the secondary carrier frequency, the UE shall report the measurement report, and the network side is in the subset of the primary carrier frequency activation set. The establishment and deletion of the connection between the UE and the secondary carrier frequency cell are determined according to the reported event in the range. Specifically, it can be:
当 UE上报的测量报告中指示多载波小区的辅载频信号质量高于 预定门限时， 将该多载波小区加入辅载频的激活集；  When the quality of the secondary carrier frequency signal of the multi-carrier cell is higher than the predetermined threshold in the measurement report reported by the UE, the multi-carrier cell is added to the active set of the secondary carrier frequency;
当 UE上报的测量报告中指示该多载波小区的辅载频信号质量低 于预定门限时， 将该多载波小区从辅载频的激活集中删除；  When the measurement report reported by the UE indicates that the quality of the secondary carrier frequency signal of the multi-carrier cell is lower than a predetermined threshold, the multi-carrier cell is deleted from the active set of the secondary carrier frequency;
维护辅载频的激活集还可以为：  The active set that maintains the secondary carrier frequency can also be:
当 UE上报的测量报告中指示多载波小区集合中使用辅载频的小 区的信号质量高于预定门限时，将该使用辅载频的小区加入辅载频的 激活集；  When the signal quality of the cell using the secondary carrier frequency in the multi-carrier cell set is higher than the predetermined threshold in the measurement report reported by the UE, the cell using the secondary carrier frequency is added to the active set of the secondary carrier frequency;
当 UE上报的测量报告中指示该多载波小区集合中使用辅载频的 小区的信号质量低于预定门限时，将该使用辅载频的小区从辅载频的 激活集中删除。  When the measurement report reported by the UE indicates that the signal quality of the cell using the secondary carrier frequency in the multi-carrier cell set is lower than a predetermined threshold, the cell using the secondary carrier frequency is deleted from the active carrier of the secondary carrier frequency.
三、 当下行采用 K1/K3组网结构时，  3. When the downlink adopts the K1/K3 networking structure,
下行同时使用两个载频， 其中一个载频对所有扇区都是相同的， 另一个载频对基站的 3个扇区是不同的， 采用 K3复用方式以减小小区 间的干 4尤， 此时组网形式如图 2所示。  The downlink uses two carrier frequencies at the same time, one carrier frequency is the same for all sectors, and the other carrier frequency is different for the three sectors of the base station, and the K3 multiplexing method is adopted to reduce the inter-cell dry 4 At this time, the networking form is shown in Figure 2.
对于 K1/K3组网场景， 网络侧可以通过以下方法维护激活集： ( 1 )如果下行只有 DCH, 那么它只能在 DL1上传输， 如果上行 业务也只使用一个载频， 那么， 它的切换判决和单载波系统相同。 如 果上行业务同时使用两个载频，由于不能获得 UL2的信号质量，因此， UL2的 E-DCH激活集和 UL1相同。  For the K1/K3 networking scenario, the network side can maintain the active set by the following methods: (1) If the downlink only has DCH, then it can only transmit on DL1. If the uplink service uses only one carrier frequency, then its switching The decision is the same as for a single carrier system. If the uplink service uses two carrier frequencies at the same time, the UL-E-DCH active set is the same as UL1 because the signal quality of UL2 cannot be obtained.
( 2 )如果下行有 HSDPA同时使用两个载频， 但上行只使用一个 载频， 上行使用的这个载频与下行使用的两个载频中的一个相同（是 指相互配对， WCDMA中的下行和上行的频点是配对的）， 这时当在 下行使用的另一个载频上触发 UE上报测量报告指示信号质量高于预 设门限时， UE在下行使用的另一个载频上与 HSDPA服务小区建立连 接；  (2) If HSDPA is used at the same time, but two carrier frequencies are used at the same time, but only one carrier frequency is used for the uplink, the carrier frequency used in the uplink is the same as one of the two carrier frequencies used in the downlink (refers to mutual pairing, downlink in WCDMA) And the uplink frequency point is paired. When the UE reports the measurement report indicating that the signal quality is higher than the preset threshold on another carrier frequency used in the downlink, the UE uses the HSDPA service on another carrier frequency used in the downlink. The cell establishes a connection;
当在下行使用的另一个载频上触发 UE上报测量报告指示信号质 量低于预设门限事件时， UE在下行使用的另一个载频上与 HSDPA服 务小区的连接被拆除。 Triggering the UE to report the measurement report indicating the signal quality on another carrier frequency used in the downlink When the amount is lower than the preset threshold event, the UE's connection with the HSDPA serving cell on the other carrier frequency used in the downlink is removed.
( 3 )如果下行有 HSDPA同时使用两个载频， 上行也同时使用两 个载频， 这种场景也只能以 DL1作为主载频， UL2的 E-DCH激活集和 UL1相同。 是否和 DL2、 DL3或 DL4建立连接由 UE上报的测量报告决 定。  (3) If there are two carrier frequencies for HSDPA in the downlink and two carrier frequencies for the uplink, this scenario can only use DL1 as the primary carrier frequency. The E-DCH active set of UL2 is the same as UL1. Whether the connection with DL2, DL3 or DL4 is established is determined by the measurement report reported by the UE.
上述切换处理的方法， 也可以适用于包括 3个以上扇区的基站， 即下行同时使用两个载频， 其中一个载频对所有扇区都是相同的， 另 一个载频对基站的 3个以上的扇区是不同的。  The foregoing handover processing method may also be applied to a base station including three or more sectors, that is, two carrier frequencies are simultaneously used in downlink, one carrier frequency is the same for all sectors, and the other carrier frequency is three for the base station. The above sectors are different.
上述切换处理的方法， 是以 UE的上行或下行链路同时使用一个 或两个载频为例进行说明的， 但是该切换处理的方法同样适用于 UE 的上行或下行链路使用一个或多个载频的场景， 在此不再赘述。  The method for the handover process is described by using one or two carrier frequencies simultaneously in the uplink or downlink of the UE, but the method of the handover process is also applicable to one or more uplink or downlink use of the UE. The carrier frequency scenario will not be described here.
本发明实施例根据 UE上报的测量报告维护激活集， 更新 UE的服 务小区， 可以在多载波 CDMA通信系统中， 进行用户移动时的小区间 切换， 提高了用户的服务体验。 进一步地， 通过限制辅载频激活集为 主载频激活集的子集， 可以筒化激活集的维护操作； 通过限制主载频 和辅载频的服务小区保持一致， 便于两载波之间的联合调度， 有利于 调度算法的性能提升。  The embodiment of the present invention maintains an active set according to the measurement report reported by the UE, and updates the serving cell of the UE, and can perform inter-cell handover when the user moves in the multi-carrier CDMA communication system, thereby improving the service experience of the user. Further, by limiting the secondary carrier frequency activation set as a subset of the primary carrier frequency activation set, the maintenance operation of the active set can be centralized; the serving cell that restricts the primary carrier frequency and the secondary carrier frequency is consistent, and is convenient between the two carriers. Joint scheduling is beneficial to the performance improvement of the scheduling algorithm.
本发明实施例二提供了另一种切换处理的方法，其选择主载频的 方法与本发明实施例一选择主载频的方法基本相同。主要区别在于本 发明实施例二在上、下行同时使用多个载频时对辅载频的激活集单独 维护， 例如：  The second embodiment of the present invention provides another method for switching processing. The method for selecting the primary carrier frequency is substantially the same as the method for selecting the primary carrier frequency according to the first embodiment of the present invention. The main difference is that in the second embodiment of the present invention, when a plurality of carrier frequencies are simultaneously used in uplink and downlink, the activation set of the secondary carrier frequency is separately maintained, for example:
( 1 ) 当上、 下行同时使用多个载频时， 对多个载频分别配置同 频测量， UE根据网络侧下发的测量控制消息对辅载频进行测量， 决 定是否触发信号质量变化的上报。 网络侧对辅载频根据 UE上报的信 号质量变化的事件维护激活集， 决定链路的建立和删除。  (1) When multiple carriers are used in the uplink and downlink, the same frequency measurement is configured for multiple carrier frequencies. The UE measures the secondary carrier frequency according to the measurement control message sent by the network to determine whether to trigger the signal quality change. Reported. The network side maintains an active set for the event that the secondary carrier frequency changes according to the quality of the signal reported by the UE, and determines the establishment and deletion of the link.
( 2 ) 由于主载频和辅载频的激活集都根据各自的信号质量变化 事件维护， 因此， 主载频和辅载频激活集中的信号质量最好的小区可 能不一致。 但 HSPA的服务小区要尽可能和主载频激活集中的最好小 区保持一致。 因此， 当 HSPA的服务小区不在辅载频激活集中时， 需 要将它加入辅载频激活集中。 如果此时辅载频的激活集已满， 则用它 替换辅载频激活集中信号质量最差的小区。 (2) Since the active sets of the primary carrier frequency and the secondary carrier frequency are all maintained according to their respective signal quality change events, the cells with the best signal quality in the primary carrier frequency and the secondary carrier frequency activation set may be inconsistent. However, the HSPA service area should be as small as possible and the best of the main carrier frequency activation set. The district remains consistent. Therefore, when the serving cell of the HSPA is not in the secondary carrier frequency activation set, it needs to be added to the secondary carrier frequency activation set. If the active set of the secondary carrier frequency is full at this time, it is used to replace the cell with the worst signal quality in the secondary carrier frequency active set.
本发明实施例通过对辅载频的激活集的单独维护， 有利于 UE在 主载频和辅载频上都尽量和信号质量最好的链路保持连接， 可以为 UE提供更好的服务。  In the embodiment of the present invention, by separately maintaining the active set of the secondary carrier frequency, the UE can be connected to the link with the best signal quality on the primary carrier frequency and the secondary carrier frequency, and can provide better service for the UE.
本发明实施例三还提供了另外一种切换处理的方法，其与实施例 二的主要区别在于：本发明实施例三中的切换处理方法可以根据多个 载频的信号质量和负载情况决定服务小区。 当某个小区的某个载频触 发 Id事件上报时， UE会同时上报激活集、 监视集和检测集内所有小 区的所有载频的信号质量。 如果主载频和辅载频的最好小区不一致 (一般来说， 即使不一致， 信号质量也不会相差很多 ) , 则优先选择 下行负载较低的小区作为服务小区。  The third embodiment of the present invention further provides another method for switching processing, and the main difference from the second embodiment is that the switching processing method in the third embodiment of the present invention can determine the service according to the signal quality and load conditions of multiple carrier frequencies. Community. When a certain carrier frequency triggering Id event is reported in a cell, the UE reports the signal quality of all carrier frequencies of the active set, the monitoring set, and all the cells in the detection set. If the best cell of the primary carrier frequency and the secondary carrier frequency are inconsistent (generally, even if the signal quality does not differ much if it is inconsistent), the cell with the lower downlink load is preferentially selected as the serving cell.
本发明实施例根据多个载频的信号质量和负载情况决定服务小 区， 有利于将负载较低的小区作为用户的 HSDPA服务小区， 有助于 提升用户的下行吞吐率。  The embodiment of the present invention determines the service area according to the signal quality and the load condition of multiple carrier frequencies, and is beneficial to the lower load cell as the user's HSDPA serving cell, which helps to improve the downlink throughput rate of the user.
本发明实施例四还提供了另外一种切换处理的方法，其与实施例 二的主要区别在于： 根据 UE上报的测量报告维护主载频和辅载频的 激活集， 主载频和辅载频的激活集可以不一致， 主载频和辅载频的信 号质量最好的小区， 以及服务小区也可以不一致。 此时主载频和辅载 频的激活集可以没有关系。  The fourth embodiment of the present invention further provides another method for handover processing, and the main difference from the second embodiment is: maintaining an active set of the primary carrier frequency and the secondary carrier frequency according to the measurement report reported by the UE, the primary carrier frequency and the secondary carrier. The frequency activation set may be inconsistent, and the cell with the best signal quality of the primary carrier frequency and the secondary carrier frequency, and the serving cell may also be inconsistent. At this time, the active set of the primary carrier frequency and the secondary carrier frequency can be irrelevant.
本发明实施例不限定主载频和辅载频的激活集之间的关系，有利 于在主载频和辅载频上都以各自信号质量最好的小区作为服务小区， 为 UE提供更好的服务。  The embodiment of the present invention does not limit the relationship between the active set of the primary carrier frequency and the secondary carrier frequency, and is beneficial to the cell with the best signal quality as the serving cell on both the primary carrier frequency and the secondary carrier frequency, thereby providing better UEs. Service.
