本发明的较佳实施方式 为了便于本领域技术人员的理解, 下面结合附图对本发明作进一步的描 述, 并不能用来限制本发明的保护范围。 Preferred embodiment of the invention In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings, and is not intended to limit the scope of the present invention.
图 1为本发明实施例小区重选方法的流程图, 如图 1所示, 本发明实施 例的方法包括:  FIG. 1 is a flowchart of a cell reselection method according to an embodiment of the present invention. As shown in FIG. 1, the method in the embodiment of the present invention includes:
步骤 100、 获取移动终端的能力;  Step 100: Acquire a capability of the mobile terminal.
步骤 101、 对当前小区发起重选请求, 并对当前小区的邻小区发起测量; 步骤 102、 判断所获取的移动终端的能力是以数据为中心还是以语音为 中心;  Step 101: Initiate a reselection request for the current cell, and initiate a measurement to the neighboring cell of the current cell. Step 102: Determine whether the acquired mobile terminal is centered on data or voice;
步骤 103、 根据移动终端的能力和邻小区的测量结果进行小区重选。 具 体实现如下文步骤 205 210所述。  Step 103: Perform cell reselection according to the capability of the mobile terminal and the measurement result of the neighboring cell. The specific implementation is as described in step 205 210 below.
图 2为本发明实施例小区重选方法的实施例的流程图, 如图 2所示, 包 括:  2 is a flowchart of an embodiment of a cell reselection method according to an embodiment of the present invention. As shown in FIG. 2, the method includes:
步骤 201、 移动终端开机启动, 读取非易失存储器 (NV, Nonvolatile Memory ) 中终端能力的配置信息, 获取当前终端的能力;  Step 201: The mobile terminal starts up, reads configuration information of the terminal capability in the non-volatile memory (NV, Nonvolatile Memory), and acquires the capability of the current terminal;
步骤 202、移动终端进行正常网络注册,公共陆地移动网络( PLMN, Public Step 202: The mobile terminal performs normal network registration, and the public land mobile network (PLMN, Public
Land Mobile Network )选择、 小区选择、 位置更新、 路由更新操作, 获取正 常网络服务。 Land Mobile Network) Select, Cell Select, Location Update, Route Update Operation, Get Normal Network Service.
步骤 203、 当前小区的网络服务质量较差时, 移动终端向当前小区发起 小区重选请求, 并根据测量条件对邻小区发起测量;  Step 203: When the network service quality of the current cell is poor, the mobile terminal initiates a cell reselection request to the current cell, and initiates measurement on the neighboring cell according to the measurement condition.
移动终端具有实时检测当前小区的网络服务质量的功能, 当当前小区的 网络服务质量较差时, 如移动终端发生掉线或者网速较慢时, 移动终端会自 动对当前小区发起重选请求, 并根据测量条件对邻小区发起测量, 之后当前 小区不再为移动终端服务。 具体实现属于本领域技术人员的惯用手段, 这里 不再赘述。  The mobile terminal has the function of detecting the network service quality of the current cell in real time. When the network service quality of the current cell is poor, such as when the mobile terminal is disconnected or the network speed is slow, the mobile terminal automatically initiates a reselection request for the current cell. And the measurement is initiated on the neighboring cell according to the measurement condition, and then the current cell no longer serves the mobile terminal. The specific implementation is a conventional means by those skilled in the art, and will not be described here.
步骤 204、 判断当前终端的能力, 如果当前终端的能力是以语音为中心, 则执行步骤 205 , 否则执行步骤 206。  Step 204: Determine the capability of the current terminal. If the capability of the current terminal is voice-centric, perform step 205, otherwise perform step 206.
移动终端的能力主要分为以数据为中心和以语音为中心, 以数据为中心 是指移动终端的业务以数据为主, 如移动终端一般用于上网, 而很少用于打 电话; 以语音为中心是指移动终端的业务以语音为主, 如移动终端一般用于 打电话, 而很少用于上网。 本步骤中根据移动终端的配置信息有关移动终端 能力的取值进行判断, 具体的判断方法属于本领域技术人员的惯用手段, 其 具体实现并不用于限定本发明实施例的保护范围, 这里不再赘述。 例如, 当 移动终端能力的取值为 0时, 则表示移动终端的能力为以语音为中心, 当移 动终端能力的取值为 1时, 则表示移动终端的能力以数据为中心。 The capabilities of mobile terminals are mainly divided into data-centric and voice-centric. Data-centric refers to the mobile terminal's services are mainly data, such as mobile terminals are generally used for Internet access, and rarely used for making calls; For the center, the mobile terminal's services are mainly voice, such as mobile terminals are generally used for Calling, and rarely used to go online. In this step, the value of the mobile terminal is determined according to the configuration information of the mobile terminal. The specific determination method is a conventional method of the person skilled in the art, and the specific implementation is not used to limit the protection scope of the embodiment of the present invention. Narration. For example, when the value of the mobile terminal capability is 0, it indicates that the capability of the mobile terminal is centered on voice, and when the value of the mobile terminal capability is 1, it indicates that the capability of the mobile terminal is data-centric.
步骤 205、 当前终端的能力是以语音为中心, 也就是以语音业务为主, 则按照测量到的邻小区的测量信息, 如时延、 抖动、 丟包率、 回声, 根据公 式: (时延 X 0.4+抖动 X 0.1+丟包率 X 0.4+回声 0.1 ) 的计算结果将邻小区 按照从小到大的顺序排列, 排序之后, 优先选择计算结果最小的邻小区。 之 后结束本流程。  Step 205: The capability of the current terminal is voice-centric, that is, the voice service is mainly, according to the measured measurement information of the neighboring cell, such as delay, jitter, packet loss rate, and echo, according to the formula: (delay) The calculation result of X 0.4+ jitter X 0.1+ packet loss rate X 0.4 + echo 0.1 ) ranks the neighboring cells in order from small to large, and after sorting, the neighbor cells with the smallest calculation result are preferentially selected. Then the process ends.
本步骤中, 移动终端的能力是以语音为中心, 那么主要考虑与语音服务 相关的参数进行小区重选, 而不需要考虑与数据服务相关的参数, 那么重选 的小区必然能够满足移动终端的语音需求, 而不会发生再次进行小区重选的 情况, 因此重选效率高。  In this step, the capability of the mobile terminal is centered on voice, and then the cell reselection is mainly considered in consideration of the parameters related to the voice service, and the parameters related to the data service need not be considered, so the reselected cell must be able to satisfy the mobile terminal. The voice demand is not repeated for cell reselection, so the reselection efficiency is high.
步骤 206、 当前的终端能力是以数据为中心, 也就是以数据交互为主, 则根据测量到的测量信息, 判断邻小区的接入制式是否相同, 如果相同则进 入步骤 208 , 否则执行步骤 207。  Step 206: The current terminal capability is data-centric, that is, data interaction is dominant, and according to the measured measurement information, it is determined whether the access system of the neighboring cell is the same. If the same, the process proceeds to step 208, otherwise, step 207 is performed. .
邻小区的接入制式指邻小区所在的网络是 2G、 3G还是 4G。 具体的判断 方法属于本领域技术人员的惯用手段, 其具体实现并不用于限定本发明的保 护范围, 这里不再赘述。  The access system of the neighboring cell refers to whether the network where the neighboring cell is located is 2G, 3G or 4G. The specific method of the present invention is not intended to limit the scope of protection of the present invention, and details are not described herein.
步骤 207、 根据邻小区所在无线网络的能力对小区进行排序, 顺序依次 是 4G, 3G, 接下来是 2G。 即优先选择 4G, 其次是 3G, 最后才是 2G。 之后 结束本流程。  Step 207: Sort the cells according to the capabilities of the wireless network where the neighboring cell is located, and the order is 4G, 3G, and then 2G. That is, 4G is preferred, followed by 3G, and finally 2G. Then end this process.
步骤 208、 根据测量到的测量信息, 判断测量的邻小区的能力是否相同, 如果相同则执行步骤 209, 否则执行步骤 210;  Step 208: Determine, according to the measured measurement information, whether the measured neighboring cells have the same capability, if yes, perform step 209, otherwise perform step 210;
例如, 对于 3G小区, 如果邻小区的能力均是 DC-HSPA+, 或者 HSPA+, 或者 HSDPA, 或者 UMTS, 则小区能力相同, 否则不同。 对于 2G小区如果 邻小区能力均是 EDGE, 或者 GPRS, 或者 GSM则小区能力相同, 否则则不 相同。 本步骤的具体的判断方法属于本领域技术人员的惯用手段, 其具体实 现并不用于限定本发明实施例的保护范围, 这里不再赘述。 步骤 209、 按照邻小区信号强度对邻小区进行排序, 优先选择信号最强 的小区为重选小区; 之后结束本流程。 For example, for a 3G cell, if the capabilities of the neighboring cells are both DC-HSPA+, or HSPA+, or HSDPA, or UMTS, the cell capabilities are the same, otherwise different. For a 2G cell, if the neighboring cell capabilities are all EDGE, or GPRS, or GSM, the cell capabilities are the same, otherwise they are different. The specific method of the present invention is not limited to the scope of protection of the embodiments of the present invention, and is not described herein. Step 209: Sort the neighboring cells according to the signal strength of the neighboring cell, and select the cell with the strongest signal as the reselected cell; and then end the process.
按照 3GPP协议 TS25.304对于 FDD或者 TDD小区可以按照码片能量 / 干扰功率密度(Ec/Io )或者接收信号码功率(RSCP, Received Signal Code Power )进行排序, 优先选择 Ec/Io或者 RSCP最大的小区; 对于 GSM小区 可以按照接收的信号强度指示(RSSI, Received Signal Strength Indication )进 行小区排序, 优先选择 RSSI最大的小区; 对于 LTE小区按照参考信号接收 功率 (RSRP , Reference Signal Receiving Power ) 或者参考信号接收质量 ( RSRQ, Reference Signal Receiving Quality )进行排序, 优先选择 RSRP或 者 RSRQ最大的小区。 具体的排序方法属于现有技术, 其具体实现并不用于 限定本发明实施例的保护范围, 这里不再赘述。  According to the 3GPP protocol TS25.304, the FDD or TDD cell can be sorted according to chip energy/interference power density (Ec/Io) or received signal code power (RSCP, Received Signal Code Power), and the Ec/Io or RSCP is the largest. For the GSM cell, the cell may be sorted according to the Received Signal Strength Indication (RSSI), and the cell with the largest RSSI is preferentially selected; for the LTE cell, the reference signal receiving power (RSRP, Reference Signal Receiving Power) or the reference signal is used. Receive quality (RSRQ, Reference Signal Receiving Quality) is sorted to preferentially select the cell with the largest RSRP or RSRQ. The specific method of the present invention is not limited to the scope of protection of the embodiments of the present invention, and details are not described herein again.
步骤 210、 测量邻小区能力不相同时, 按照邻小区的能力进行排序; 优 先选择能力最强的小区为重选小区;  Step 210: When the capabilities of the neighboring cells are different, the resources are sorted according to the capabilities of the neighboring cells; the cell with the strongest selection capability is the reselected cell;
对于 3G小区, DC-HSPA+小区能力强于 HSPA+小区, HSPA+小区能力 强于 HSDPA, HSDPA的小区能力强于 UMTS的小区; 对于 2G小区, 支持 EDGE的小区性能优于 GPRS小区,支持 GPRS的小区能力优于支持 GSM的 小区。  For a 3G cell, the DC-HSPA+ cell capability is stronger than the HSPA+ cell, the HSPA+ cell capability is stronger than the HSDPA, and the HSDPA cell capability is stronger than the UMTS cell; for the 2G cell, the EDGE-enabled cell performance is better than the GPRS cell, and the GPRS-capable cell capability is supported. Better than a cell that supports GSM.
步骤 206-210 中, 移动终端的能力是以数据为中心, 那么主要考虑与数 据服务相关的参数进行小区重选, 而不需要考虑与语音服务相关的参数, 那 么重选的小区必然能够满足移动终端的数据需求, 而不会发生再次进行小区 重选的情况, 因此重选效率高。  In steps 206-210, the capability of the mobile terminal is data-centric, and then the cell reselection is mainly considered in consideration of parameters related to the data service, and the parameters related to the voice service need not be considered, so the reselected cell must be able to satisfy the mobile. The data demand of the terminal does not occur in the case of cell reselection again, so the reselection efficiency is high.
