Description

一种系统消息接收的方法和终端设备 技术领域
本发明涉及无线通信领域， 尤其涉及长期演进 ( LTE , Long Term Evolution )和蓝牙（ Bluetooth )这两种无线电技术共存于同一终端设备（ UE, User Equipment ) 内时， 一种系统消息接收的方法和终端设备。 背景技术
随着无线电技术的发展， 越来越多的无线电技术开始被广泛应用， 尤 其为了满足终端客户的多种通信技术需求， 在同一个智能终端内， 将同时 使用多种无线电技术， 例如 LTE/Bluetooth (蓝牙）。 如图 1所示， 是一种同 时使用多种无线电技术的终端设备的示意图， 在该终端设备 100 中， 设计 使用了多种无线电技术， 分别是模块 101使用 LTE技术， 模块 102使用无 线局域网客户端（WLAN-STA, Wireless Local Area Network-station )技术， 模块 103使用 Bluetooth技术。 终端设备 100的三个模块分别与各自无线电 技术所对应的对端设备进行无线通信， 其中， 模块 101与 LTE-eNB (演进 型基站， E-UTRAN NodeB ) 104通过空中接口进行无线通信； 模块 102与 另一个 WLAN-STA设备 105通过空中接口进行无线通信；模块 103与另一 个 Bluetooth设备 106通过空中接口进行无线通信。 101和 102这两个模块 之间通过无线电技术之间的接口 （inter-radio interface )相连， 比如 101与 102 之间通过接口 L101 相连； 或者两个模块受控于一个公共的控制设备 107。
同一个终端设备内具备多种无线电技术， 然而鉴于终端设备的体积太 时， 这两种或两种以上的无线电技术所在的模块之间的空间距离会相隔很 近， 口相隔几个厘米， ^L^ ^ I^ ^f ^ l^ ^f ^
端口之间的空间隔离度无法设计的足够大， 从而会导致以下情况的出现： 如果同一个终端设备内的各无线电技术使用相邻的频带， 那么由于带外泄 露 ( Out of band emission )、 杂散发射 ( Spurious emissions )等原因, 当其中 一个无线电技术模块进行发射时， 将干扰另一个无线电技术模块的接收， 反之亦然， 而且这种干扰又无法通过现有滤波器消除， 从而会影响各无线 电技术模块的通信质量。 上述干扰也称为 "设备内共存干扰"。
以图 1所示的终端设备 100为例， Bluetooth使用工业、科学及医疗（ ISM, Industrial Scientific and Medical ) 频带 （ 即 2.4GHz~2.5GHz ) 中的 2.4GHz~2.497GHz频段， 而 ISM 频带正好与 LTE 的频带 40 ( Band40: 2.3GHz~2.4GHz )和频带 7的上行频带 （ Band7 UP: 2.5GHz~2.57GHz )相 邻， 如图 2所示。 因此， 如果模块 101使用时分双工（TDD, Time Division Duplex )模式且正好使用 Band40, 或者模块 101 使用频分双工 （FDD , Frequency Division Duplex )模式且上行正好使用了 Band7, 那么模块 101 与 102之间将会相互干扰， 具体干扰情况如下表 1所示：
LTE Band 40与 ISM频带之间的干扰情况
ISM干 ISM频带低频段（比 干扰整个 LTE Band 40,且干扰很强（大 扰 LTE 如低 20MHz频段） 于 50dB )
ISM其余频段 干扰 LTE Band 40的高频段（比如高
20MHz频段）
LTE干 Band 40高频段（比 干扰整个 ISM频带
扰 ISM 如高 30MHz频段）
Band 40其余频段 干扰 ISM低频段（比如低 20MHz频段）， 且干扰很强 （大于 50dB )
LTE Band 7上行与 ISM频带之间的干扰情况 LTE干 Band 7低频段（比如 干扰整个 ISM频段且干扰很强 （大于 扰 ISM 氐 10MHz频段 ) 50dB )
Band 7其余频段 干扰 ISM高频带（比如高 30MHz频段） 如图 2所示， 由于 LTE Band 7与 ISM频带相隔很远， 因此 ISM不干扰
LTE Band 7的下行
表 1
从上述表 1中可以看出， 当 LTE工作在 Band 40时 , 将被 ISM设备干 扰， 从而会降低通信质量， 影响用户的通信体验。 对于 LTE技术， UE在开 机后会进入空闲 （IDLE )状态， 在这个状态下 UE没有业务数据产生， 而 eNB会周期性的发送寻呼（ paging ) /主系统信息块（ MIB , Master Information Block ) /系统信息块 1 ( SIBl , System Information Block 1 ) /系统消息 （ SI message , System Information message ) , UE 周期性接收这些消息。 对于 Bluetooth技术，其工作在 ISM频带， UE的 Bluetooth模块开始数据传输后， 进行周期性的发送 /接收，但与 LTE paging/MIB/SIB 1/SI message具有不同的 周期。如果 UE内 Bluetooth发送数据时正好是 LTE接收 paging/MIB/SIB 1/SI message的时机， 则所述 paging/MIB/SIB 1/SI message将被干扰而导致 UE 无法正确接收到所述 paging/MIB/SIB 1/SI message, 从而影响 UE接收或者 更新系统消息的时间， 导致一段时间内 UE 内的系统消息配置信息与 eNB 的配置不匹配，进而影响 UE在该段时间内发起业务时的成功概率，严重情 况下甚至会导致 UE无法找到合适的小区驻留最终影响用户体验。 发明内容
有鉴于此， 本发明的主要目的在于提供一种系统消息接收的方法和 UE, 以解决 LTE与 Bluetooth共存于同一 UE内时， 由于 Bluetooth对 LTE 的干扰导致 UE无法接收或无法及时接收到系统消息，而影响用户体验的问 题。 为达到上述目的， 本发明的技术方案是这样实现的：

所述 LTE系统消息包括以下至少之一：寻呼消息、主系统信息块（ MIB )、 系统信息块 1 ( SIB1 )和系统消息 ( SI message )。
本发明还提供了一种 UE, 包括：

下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 如图 3 所示， 是 Bluetooth扩展同步面向连接方式（eSCO , extended Synchronous Connection Oriented ) 下釆用单时隙数据包时的帧结构示意图。 其中， Bluetooth的每一帧由 6个 0.625ms的时隙 （slot )构成， 每一帧的总 长度为 3.75ms。 其中， 前两个 slot为预留 slot, master-to-slave (简称 M ) 时隙预留用于主蓝牙设备 ( master ) 向从蓝牙设备 （slave ) 发送数据， slave-to-master (简称 N )时隙预留用于 slave向 master发送数据。 其余的四 个 slot构成重传窗口 （ Retransmission window ), 用于进行数据重传， 即当 Bluetooth在预留的两个时隙内传输数据不成功时， Bluetooth会使用重传窗 口内的时隙进行数据重传。
再如图 4所示， 是 LTE与 Bluetooth帧边界之间的偏移差 （offset )示 意图， 其中：
T1表示 LTE paging/MIB/SIBl的周期或 SI— window的长度；
T2表示 Bluetooth的帧长度（ 3.75ms );
a表示 LTE子帧的长度（ 1ms );
b表示 Bluetooth时隙的长度（ 0.625ms );
offset表示 LTE与 Bluetooth帧边界之间的偏移量， 由于 Bluetooth的帧 长度为 3.75ms, 以 3.75ms为周期进行重复， 那么 offset的取值范围为 [0, 3.75]ms。
如果 Bluetooth的 master-to-slave时隙与 LTE的下行子帧有时域上的重 叠，该下行子帧将被 Bluetooth干扰。具体的，如果 LTE的 paging/MIB/SIBl/SI message在时 i或上与 Bluetooth的 master-to-slave时隙发生重叠， 则 LTE的 paging/MIB/SIBl/SI message接收将被干扰。
经过遍历 offset在 [0, 3.75]之间的不同取值以及不同的 T1周期，发现， 当 LTE 与 Bluetooth 帧边界之间的 offset 取不同参数时， LTE 的 paging/MIB/SIBl/SI message接收时机被干扰的情况有所不同。 干扰情况如 下：
对于 paging消息， 当 offset取特定值 X时， X为 [0.625 , 1]范围之间的 值、 或者 [1.875 , 2.25]范围之间的值、 或者 [3.125 , 3.5]范围之间的值， 无论 paging周期（ T1 )怎样取值，UE都将有连续两个接收 paging消息的时机（ PO, Paging Occasion )被 Bluetooth干扰； 而在 offset取特定值 Y值时， Υ为除 上述所列 X值范围之外且满足 [0, 3.75]的其他值， UE接收 paging消息的 时机 PO被干扰的概率将大大减少，比如每两个 PO中只有一个 PO被干扰。 此外， 对 paging周期 T1进行不同的取值遍历时， 还发现， eNB所配置的 paging周期 T1越大， UE的 PO被干扰的概率越小， 比如： 当 offset取特定 值 Y, paging周期为 2560ms时 PO被干扰的概率， 远小于 paging周期为 320ms时 PO被干扰的概率。 所以， eNB 可以为所控制的小区配置较大的 paging周期 ( defaultPagingCycle )参数， 以减小 paging消息被干扰的 4既率。
LTE系统中， 当 UE驻留到一个小区后， 需要定期检查本小区的系统消 息是否已经修改， 具体的更新检查方法如图 5所示， eNB为 UE配置系统 消息更新周期因子 （ modificationPeriodCoeff ) 以 及 paging 周期 ( defaultPagingCycle )等参数， 具体的：
系统消息更新周期 = modificationPeriodCoeff x defaultPagingCycle 当 eNB需要更新系统消息时， eNB提前一个系统消息更新周期 （如图 5所示的系统消息更新周期 n )向 UE发送 paging消息， 该 paging消息指示 UE系统消息发生改变。 UE根据 paging接收算法， 在系统消息更新周期 n 中该 UE对应的各 PO接收 paging消息， 直到接收成功为止。 UE在系统消 息更新周期 n中最多有 modificationPeriodCoeff次 PO,即 UE在系统消息更 新周期 n中最多有 modificationPeriodCoeff次机会接收 paging消息。
根据上述 Bluetooth对 paging 的干扰分析， 发现， 当 eNB 所配置的 modificationPeriodCoeff为 2时， 而 LTE与 Bluetooth帧边界之间的偏移量 ( offset )取特定值 X时， UE在系统消息更新周期 n内很有可能将无法接 收到 paging 消息， 从而导致 UE 无法获知系统消息更新的信息。 而如果 modificationPeriodCoeff取值大于 2,则 UE在系统消息更新周期 n内至少可 以接收到一次 paging消息。 与 paging消息的干扰情况类似，对于 MIB, SIB1和 SI message,当 offset 取特定值 X时， X为 [0.625 , 1]范围之间的值、 或者 [1.875 , 2.25]范围之间 的值、 或者 [3.125 , 3.5]范围之间的值， MIB/SIB1/SI message被干扰的概率 最大； 而当 offset取特定值 Y时， Y为除上述所列 X值范围之外且满足 [0, 3.75]的其他值时， MIB/SIB1/SI message被干扰的概率较小， 可以保证 UE 在较短的时间内读取到 MIB/SIB1/SI message,保证 UE及时更新系统消息。
基于以上的发现和分析， 为了解决 LTE与 Bluetooth共存于同一 UE内 时， 由于 Bluetooth对 LTE的干扰导致 UE无法接收或者无法及时接收到系 统消息， 而影响用户体验的问题， 本发明提出一种系统消息的接收方法， 主要包括以下两种方案：
方案一： UE调整 LTE与 Bluetooth的帧边界偏移量（ offset )为特定值 Y, 或者 UE调整 LTE与 Bluetooth的帧边界 offset不为特定值 X； 其中， 特定值 X为 [0.625 , 1 ]范围之间的值、或 [ 1.875 , 2.25]范围之间的值、或 [3.125 , 3.5]范围之间的值， 特定值 Y为 [0, 3.75]范围内除 X值范围的其他值。
调整所述 offset值后，使得 UE可以在系统消息更新周期内接收到 LTE paging消息； 且调整所述 offset值后， 使得 UE可以及时更新系统消息（包 括读取 MIB、 SIB1、 SI message )„
进一步的， UE可以首先判断自身 LTE的工作频带是否在在 Band 40, 如果在在 Band 40, 则确定 LTE会受到 Bluetooth的干扰， 需要进行 offset 的调整； 否则， 确定 LTE不会受到 Bluetooth的干扰， 不需要进行 offset的 调整。
方案二： 网络侧 ( eNB )判断其所控制的小区工作在特定频带 ( Band 40 ) 上时， eNB 为该小区配置的较大或最大的 modificationPeriodCoeff ( modificationPeriodCoeff 的 允许取值 是 2/4/8/16 ) , 其 中 ， modificationPeriodCoeff的配置大于 2 , 即可以取值为 4/8/16。 在所述参数的配置下， UE 可以在系统消息更新周期内接收到 LTE paging消息， 及时获取系统消息更新的通知以更新系统消息。
需要说明的是， 上述两方案既可以分别独立使用， 也可以结合共同使 用。 下面结合具体实施例， 对上述两方案分别详细阐述。
如图 6所示， 为本发明方案一系统消息的接收方法示意图。 具体方案 下：
当 LTE工作在 Band 40时， 即工作在 2.3GHz-2.4GHz频段， 如果 UE 内的另外一个模块 Bluetooth开启， Bluetooth发送数据时有可能干扰 LTE , UE可以通过调整 LTE与 Bluetooth之间的帧边界差 offset, 减少 Bluetooth 对 LTE paging/MIB/SIBl/SI message的干扰概率。而如果 LTE工作在其它频 段， 不会受到 Bluetooth的干扰， 则不需进行任何操作。 以下实施步骤均基 于此说明：
步骤 601 , UE判断 Bluetooth启动。
如图 1 所示， 使用不同无线电技术的各个模块之间通过 inter-radio-interface相连， 或者各个使用不同无线电技术的各个模块同时受 控于一个公共的控制设备， 因此 UE内 LTE模块可以通过上述两种方式中 的任意一种， 获知 UE内 Bluetooth的开启 /关闭的状态。
步骤 602 , UE判断 LTE与 Bluetooth之间的帧边界差是否为特定值 Y; 或者判断 LTE与 Bluetooth之间的帧边界差是否为特定值 X。如果为特定值 Y、 或者不为特定值 X, 则执行步骤 606; 否则， 执行步骤 603。
步骤 603 , UE判断 UE内的 Bluetooth模块是否为通信双方的 master, 如果是， 则执行步骤 605; 否则， 执行步骤 604。
步骤 604, UE通过与通信对端 Bluetooth进行交互通信， 改变设备内的 Bluetooth模块为 master。
Bluetooth模块，可能处于 master/slave两种角色，只有 master才能调整 其帧边界。
步骤 605 , UE调整 LTE和 Bluetooth之间的帧边界差 offset为特定值 Y (即不为特定值 X )。
具体的， X值可以为 [0.625 , 1]范围内，或 [1.875 , 2.25]范围内，或 [3.125 , 3.5]范围内的任意值； Y为除上述 X值范围之外的 [0, 3.75]范围内的任意值。
步骤 606, UE接收系统消息， 即 UE在 PO处接收 paging消息， 如果 paging消息指示 UE系统消息改变， 则 UE接收系统消息。
对于方案二， 根据表 1可知， 当 LTE工作在 Band 40上时， UE内的 Bluetooth模块开启将有可能干扰 LTE, 尤其是当 LTE工作在 Band 40的高 频段（比如高 20MHz频段） 时， 无论 UE内的 Bluetooth工作在 ISM频段 的任意子频段， LTE都将被 Bluetooth干扰。 因此， 网络侧 （eNB )判断所 控制的小区工作在 Band 40或者 Band 40的高频段时（比如高 20MHz频段）， eNB为所述小区配置的较大或最大的 modificationPeriodCoeff, 进一步的， eNB为所述小区配置较大或最大的 defaultPagingCycle ( defaultPagingCycle 的允许取值是 32/64/128/256 )，其中所述 modificationPeriodCoeff配置大于 2。
对应上述系统消息接收的方法， 本发明还提供了一种 UE, 包括： 偏移 量调整模块和消息接收模块。 其中， 偏移量调整模块， 用于调整 UE内 LTE 与 Bluetooth的帧边界 offset为特定值 Y,或者调整 LTE与 Bluetooth的帧边 界 offset不为特定值 X；其中，特定值 X为 [0.625 , 1 ]范围之间的值、或 [ 1.875 , 2.25]范围之间的值、 或 [3.125 , 3.5]范围之间的值， 特定值 Y为 [0, 3.75]范 围内除 X值范围的其他值。 消息接收模块， 用于根据调整后的 offset进行 Bluetooth的无线传输和 LTE系统消息的接收。
进一步的， UE还包括： 工作频带判断模块， 用于判断 UE自身 LTE的 工作频带是否在 Band 40, 如果在 Band 40, 则确定 LTE会受到 Bluetooth 的干扰， 需要进行 offset的调整， 并通知偏移量调整模块； 否则， 确定 LTE 不会受到 Bluetooth的干扰， 不需要进行 offset的调整。
较佳的， 偏移量调整模块进一步用于， 在 Bluetooth启动时， 判断 LTE 与 Bluetooth的帧边界 offset是否为特定值 Y;
在判断不是特定值 Y时，继续判断 Bluetooth是否为通信双方的 master, 如果是，则直接调整 UE自身 LTE与 Bluetooth的帧边界 offset为特定值 Y; 如果不是， 则通过与通信对端 Bluetooth的交互， 改变 UE内的 Bluetooth为 master, 并调整 UE自身 LTE与 Bluetooth的帧边界 offset为特定值 Y。
综上所述，通过本发明，解决了 LTE与 Bluetooth共存于同一 UE内时， 由于 Bluetooth对 LTE的干扰导致 UE无法接收或者无法及时接收到系统消 息， 而影响用户体验的问题； 在进行上述参数配置和调整后， 使得 UE可以 在系统消息更新周期内接收到 LTE paging消息，并可以及时更新系统消息。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
