为使本发明的目的、技术方案和优点更加清楚明白,下文中将结合附图对本发明的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

如图1所示,是本发明小区的测量方法实施例的流程图,该方法包括:As shown in Figure 1, it is a flow chart of a measurement method embodiment of a cell of the present invention, the method includes:

步骤11、用户设备(UE)接收基站下发的系统信息广播,根据所述系统信息广播获得UE所在小区的半径和所述UE的寻呼时机;Step 11, the user equipment (UE) receives the system information broadcast issued by the base station, and obtains the radius of the cell where the UE is located and the paging opportunity of the UE according to the system information broadcast;

该步骤具体为:UE根据所述系统信息广播中携带的随机接入前缀的发送配置索引以及该发送配置索引与随机接入前导类型的映射关系获得所述随机接入前导类型,根据所述随机接入前导类型以及所述随机接入前导类型与小区半径的对应关系,获得UE所在的服务小区、同频邻区或异频邻区的半径,具体流程可参见图2;This step is specifically: the UE obtains the random access preamble type according to the transmission configuration index of the random access prefix carried in the system information broadcast and the mapping relationship between the transmission configuration index and the random access preamble type, and according to the random access preamble The access preamble type and the corresponding relationship between the random access preamble type and the cell radius, obtain the radius of the serving cell, the same-frequency adjacent cell or the different-frequency adjacent cell where the UE is located, and the specific process can be referred to in Figure 2;

表1给出3GPP协议定义的随机接入前导类型(Preamble Format)和小区半径的关系;随机接入前导类型与随机接入前缀的发送配置索引(PRACH Configuration Index)的映射关系在36211协议中定义如表2和表3所示,PRACH Configuration Index在系统信息广播中的系统信息块2(System Information Block 2,SIB2)中下发,如图2所示;Table 1 shows the relationship between the random access preamble type (Preamble Format) and the cell radius defined by the 3GPP protocol; the mapping relationship between the random access preamble type and the transmission configuration index (PRACH Configuration Index) of the random access prefix is defined in the 36211 protocol As shown in Table 2 and Table 3, the PRACH Configuration Index is issued in the System Information Block 2 (System Information Block 2, SIB2) in the system information broadcast, as shown in Figure 2;

表1Preamble Format和小区半径的关系Table 1 Relationship between Preamble Format and cell radius

表2Preamble Format与PRACH Configuration Index的映射关系Table 2 Mapping relationship between Preamble Format and PRACH Configuration Index

表3Preamble Format与PRACH Configuration Index的映射关系Table 3 Mapping relationship between Preamble Format and PRACH Configuration Index

步骤12、该UE估算出空闲态下自身的速度;Step 12, the UE estimates its own speed in the idle state;

LTE协议定义了三种UE速度状态:低速、中速、高速,它适用于UE空闲态和连接态;The LTE protocol defines three UE speed states: low speed, medium speed, and high speed, which are applicable to UE idle state and connected state;

空闲态下,协议规定UE根据单位时间段内小区重选的次数来判断自身是处于低速、中速或高速状态,UE速度状态门限(即单位时间内的小区重选次数)在系统信息广播中下发,UE驻留到小区之前会从系统信息广播中读取。单位时间内小区重选的次数越多,则UE认为自身速度越高,反之则速度越低,空闲态下UE速度的判定方法是协议规定的,本文不再累述;In the idle state, the protocol stipulates that the UE judges whether it is in a low-speed, medium-speed or high-speed state according to the number of cell reselections within a unit time period. The UE speed state threshold (that is, the number of cell reselections per unit time) is included in the system information broadcast issued, the UE will read from the system information broadcast before camping on the cell. The more times the cell is reselected per unit time, the UE thinks its own speed is higher, otherwise the speed is lower. The UE speed determination method in the idle state is stipulated by the protocol, and this article will not repeat it;

步骤13、UE根据所述半径、所述速度和所述寻呼时机打开接收机进行小区测量,延长所述接收机的关闭时间。Step 13, the UE turns on the receiver to perform cell measurement according to the radius, the speed and the paging occasion, and prolongs the shutdown time of the receiver.

LTE系统要求能灵活、有效地支持各种覆盖场景,在各种覆盖场景中,其性能应满足如下协议要求:The LTE system is required to flexibly and effectively support various coverage scenarios. In various coverage scenarios, its performance should meet the following protocol requirements:

小区覆盖半径在5公里范围内,用户吞吐量和频谱效率和移动性满足协议定义的理论最大值;The cell coverage radius is within 5 kilometers, and the user throughput, spectrum efficiency and mobility meet the theoretical maximum values defined by the agreement;

小区覆盖半径在30公里范围内,移动性需求完全满足,用户吞吐量需求略微下降,而频谱效率允许明显下降;The cell coverage radius is within 30 kilometers, the mobility requirements are fully met, the user throughput requirements are slightly reduced, and the spectral efficiency is allowed to drop significantly;

能够支持100公里半径的小区覆盖;Capable of supporting cell coverage with a radius of 100 kilometers;

由此可看出,当小区覆盖半径较大时,例如小区半径为30公里,UE即便移动100米的距离,小区的参考信号接收功率(Reference Signal Receiving Power,RSRP)和参考信号接收质量(Reference Signal Receiving Quality,RSRQ)变化会非常小,当UE满足进行测量(同频测量、异频测量、异系统测量)的条件后,如果处于低速,UE没有必要一直进行测量,而可以依据自身的速度状态、测量到的服务小区RSRP、RSRQ和小区半径来调整测量的频率,延长接收机关闭时间,达到节电目的。It can be seen from this that when the cell coverage radius is relatively large, for example, the cell radius is 30 kilometers, even if the UE moves a distance of 100 meters, the reference signal receiving power (RSRP) and reference signal receiving quality (Reference Signal Receiving Power) of the cell Signal Receiving Quality (RSRQ) will change very little. When the UE meets the conditions for measurement (same frequency measurement, different frequency measurement, different system measurement), if it is at a low speed, the UE does not need to keep measuring, but can rely on its own speed. Status, measured serving cell RSRP, RSRQ and cell radius to adjust the frequency of measurement, prolong the shutdown time of the receiver, and achieve the purpose of power saving.

需要说明的是,上述实施例中接收机关闭时机不能和寻呼(Paging)时间重合;其中,UE的Paging时间36304协议已明确定义,本文不再累述;而空闲(Idle)态下UE主要做两件事情:保证UE移动性,对服务小区和邻区做测量;寻呼时机时读取Paging,保证自身能够被呼起;总之,接收机的关闭时机需要保证UE的移动性和寻呼,因此关闭接收机需要避开对服务小区、邻区的测量时机、读取Paging的时机。It should be noted that in the above-mentioned embodiments, the timing of shutting down the receiver cannot coincide with the paging (Paging) time; among them, the Paging time of the UE has been clearly defined in the 36304 protocol, and this article will not repeat it; while in the idle (Idle) state, the UE mainly Do two things: ensure UE mobility, measure the serving cell and neighboring cells; read Paging at the time of paging to ensure that it can be called; in short, the timing of closing the receiver needs to ensure UE mobility and paging , so turning off the receiver needs to avoid the timing of measuring the serving cell and neighboring cells, and the timing of reading Paging.

采用本发明,通过延长接收机的关闭时间的方式,可以在保证UE移动性和被呼叫的前提下,延长终端待机时间。By adopting the present invention, by extending the closing time of the receiver, the standby time of the terminal can be prolonged under the premise of ensuring the UE's mobility and being called.
