- a scheduling request In a Long Term Evolution (LTE) network, after a user equipment (UE), that is, a terminal accessing a network system, to initiate data transmission, a scheduling request (SR) needs to be sent to the base station first, and the terminal can use the uplink control channel.
- the sending scheduling request requests the base station to allocate the uplink shared channel resource.
- the base station After receiving the scheduling request, the base station allocates the uplink shared channel resource to the terminal for uplink data transmission when the uplink data is to be sent.
- the base station Before the base station allocates resources to the terminal for uplink data transmission, the base station also sends a radio allocation message (RRC) to the terminal, where the radio allocation message carries scheduling request resource configuration information and measurement gap (GAP) resource configuration information, which are respectively used for The sending location of the scheduling request resource and the location of the measurement gap resource are determined.

Description
LTE网络中的数据传输恢复方法、 终端及系统 技术领域
本发明涉及通信技术领域， 尤其涉及一种 LTE网络中的数据传输恢复 方法、 终端及系统。 背景技术
在长期演进 ( Long Term Evolution, LTE ) 网络中， 用户设备（ UE ) 即 终端接入网络系统后， 若要发起数据传输， 需要首先向基站发送一个调度 请求（ SR )， 终端可利用上行控制信道发送调度请求向基站请求分配上行共 享信道资源， 基站接收到该调度请求后， 当有上行数据待发时， 分配上行 共享信道资源给终端， 供终端进行上行数据传输。
基站在分配资源给终端进行上行数据传输前， 还会向终端发送无线分 配消息（RRC )， 所述无线分配消息中携带有调度请求资源配置信息及测量 间隙 （GAP ) 资源配置信息， 分别用于确定调度请求资源的发送位置及测 量间隙资源的位置。
所述调度请求资源配置信息包括调度请求配置索引 ^， 调度请求发送 周期及其子帧位置均由配置索引 确定， 具体计算公式如下：
(10 X SFN + subframe - N0FFSET SR )mod SRPenodlclty = 0其中， SFN为调度请求发送 的系统帧号， subframe为调度请求发送子帧号， NOFFSET, SR为调度请求 子帧偏移， S^„w, ^为调度请求发送周期， 可由如下表 1中的配置索引 得
表 1
资源。 终端一旦进入测量间隙资源时间， 将不允许任何上下行信道传输。 测量间隙资源有两种周期模式， 周期分别为 40ms和 80ms， 由基站下发的 测量间隙资源配置信息决定釆用何种模式。 测量间隙资源时长不论何种周 期模式都固定为 6ms。 测量间隙资源配置信息主要包括测量间隙资源周期、 测量间隙资源子帧偏移 gapoffset等， 测量间隙资源的起始位置是根据测量 间隙资源配置信息中的测量间隙资源周期、测量间隙资源子帧偏移 gapoffset 计算得出， 具体计算公式如下：
SFN mod T = FLOO (gapoffset/10);
subframe = gapoffset mod 10;
其中， T 为测量间隙资源周期的十分之一， SFN 为测量间隙资源起始 系统帧号， subframe为测量间隙资源起始子帧号。 SFN和 subframe共同决 定测量间隙资源的起始位置。
基站向终端发送的调度请求资源与测量间隙资源之间不可避免的会存 在出现冲突的情况， 如当测量间隙资源周期为 80ms， 测量间隙资源子帧偏 移 gapoffset=0， 调度请求配置索引 =78 时， 根据上述公式计算得到测量 间隙资源的系统帧号 SFN mod 8 =0， 测量间隙资源起始子帧为子帧 0， 又
由于测量间隙资源时长不论何种周期模式都固定为 6ms， 则测量间隙资源 共占用子帧 0〜子帧 5这 6个子帧。
而通过对照表 1， 调度请求的发送周期也为 80ms， 再根据计算公式， 调度请求发送的系统帧号 SFN mod 8 =0， 调度请求子帧偏移 NOFFSET,S =7^-75=3 , 则调度请求发送子帧是第 3子帧也即子帧 3。
由上可知， 调度请求的系统帧号与测量间隙资源的系统帧号完全相同 (均为 0 )， 且调度请求的发送子帧为子帧 3， 落在测量间隙资源占用的子 帧 0〜子帧 5的范围内， 则调度请求资源的发送位置与测量间隙资源的位置 重合。
终端一旦进入测量间隙资源时间， 将不允许任何上下行信道传输， 而 由于调度请求资源的发送位置与测量间隙资源的位置重合， 导致终端无法 利用上行控制信道发送调度请求， 也就无法利用上行共享信道进行任何数 据的传输， 进而无法在服务小区所处载频接收数据， 导致数据传输中断。 发明内容
