另外, 长期演进( Long Term Evolution; 以下简称: LTE )技术被认为是 4G 移动通信系统的主流技术。 LTE系统采用正交频分多址(Orthogonal Frequency Division Multiple Access; 简称: OFDMA )和多方式输入多方式输出 (Multiple Input Multiple Output; 筒称: MIMO )技术, 能够大大提高通信系统的频谱利用 率和容量。 除此之外, LTE技术能够更好的支持诸如 VoIP或视频通话等大数据 下载业务。 作为下一代主流技术, 目前一些全球领先的 CDMA/HRPD运营商决 定从现有的 HRPD网络逐步升级到 LTE。 在网络升级的过程中, 由于同时存在 HRPD和 LTE两种网络, 其中 LTE部分覆盖, HRPD完全覆盖, 一些用户需要 使用 HRPD-LTE双模终端来进行全网络的漫游。
现有技术中, 数据封装(Encapsulation )是指将来自上层的一个或多个数据 分组进行组合, 并添加包头 ( Header )或包尾( Trailer )及填充位( Pad )等, 构成一个或多个本层数据分组的过程, 一个或多个本层数据分组构成一个分组 包嚢。
控制信道 MAC协议封装一个或多个安全层数据分组,并以数据分组或分组 包囊的形式发送控制信道信息。控制信道 MAC层数据封装的过程如下:发送时, 控制信道 MAC协议先在每个安全层分组前添加 MAC层包头, 组合多个安全层 分组, 并添加控制信道包头( Control Channel Header ) 、 填充位和保留位, 构造 MAC层分组。 接收时, 控制信道 MAC协议在确认该消息的归属后, 将属于自 身的数据分组的包头、 填充位和保留位剥离, 然后将分组净荷(Payload )提交 给安全层。
控制信道消息在控制信道周期内以同步包囊( Synchronous Capsule, SC )或 异步包嚢 (Asynchronous Capsule, AC ) 的形式发送, 如图 1所示, SC只能在 特定时间传送, AC可以在控制信道周期内发送 SC以外的任何时间发送。 控制 信道周期等于 256个时隙, 在一个控制信道周期内只能发送一个 SC, 但可以发 送多个 AC。 一个 SC可以包含一个或多个控制信道 MAC层分组; 一个 AC通 常包含一个控制信道 MAC层分組, 特殊情况下可以组合多个控制信道 MAC层 分组得到扩展的 AC。 终端开机后, 通常先读取 SC。
控制信道还有一种子同步包(SSC? ) , 该包在控制信道周期中定期发送, 用于传送寻呼消息, 子同步包的发送周期较短(一般设为 64个时隙) 。 在每个 控制信道周期, 接入网 AN的每个扇区从控制信道上传输一个或多个子同步包, 每个子同步包包含一个控制信道 MAC层分组。 AN在时隙 T传输子同步包的控 制信道 MAC层分组 , T应满足如下公式: T mod 4 Offset,但 T mod 256≠ Offset, 即传送同步包时不能传送子同步包。 这里, T为以时隙为单位的系统时间。控制 信道的各种包的相对位置如图 1所示。
同步包嚢是每个控制信道周期中发送的第一个包, 同步包又分为同步休眠 包和非休眠包。 休眠包中传送最重要的系统配置方面的信息以及其它次开销消 息的签名字段, 其它开销消息都放在非休眠包中, 因此每次处于空闲的终端从 休眠状态醒来时可以只监听休眠包, 再根据休眠包中签名字段的信息确定是否 要收取非休眠包。 休眠包中传送寻呼消息和快速配置消息, 而非休眠包中携带 同步和扇区参数消息以及其它一些消息, 包括接入参数消息、 异系统邻区信息 等广播消息。 在每个控制信道周期中, AN的每个肩区在控制信道上发送一个同 步包囊,每个同步包嚢可以包含多个控制信道 MAC层分组。 同步包囊中的第一 个 MAC层分組的开始传送时间 T应满足下面的等式: T mod 256=Offset。 而该 同步包囊中的所有其它 MAC层分組在前一个分组传输结束后的最早 T, 时间开 始传输, Τ, 应满足 T' mod 4=Offset, 即至少间隔 3个时隙。 这里, T和 T' 是以时隙为单位的 CDMA 系统时间, Offset是在同步包嚢的第一个控制信道 MAC层分组的控制信道包头中规定的时隙偏移字段的值, 取值范围为 0-3个时 隙。
另外, 每个控制信道的同步包嚢的内容可能不同。 快速配置消息在每个控 制信道的同步休眠包中都要发送, 但在非休眠包中发送的消息并非在每个控制 信道周期中都需要发送, 比如扇区参数消息至少在每 4个控制信道周期中发送 一次, 接入参数消息至少在每 3个控制信道周期中发送一次, 而异系统的邻区 信息可能以更低的频率发送, 因此每个控制信道的同步包嚢的内容可能仅有同 步休眠包, 可能由单独的 MAC层分组或多个 MAC层分组构成; 同步包嚢的内 容还可能由同步休眠包与非休眠包构成, 其中非休眠包可能是单个或多个 MAC 层分组。 其中快速配置消息中带有最新的扇区参数消息和异系统邻区消息的消 息标签。这样的设置使得空闲状态的移动终端 AT可以常处于休眠状态,只需要 定时醒来去监听一下有无寻呼、 查一下快速配置消息中的消息标签有无变化, 如有则需要监听该消息标签相应的消息。
在发送控制信道 MAC层同步包囊时, 系统在每个 MAC层分组前加上包头 信 息 , 头 由 SyncCapsule 、 FirstPacket 、 LastPacket 、 Offset 和 SleepStateCapsuleDone组成。 具体而言, 对于 SyncCapsule字段, 在发送 SC的 第一个 MAC层分组时将其设为 ' Γ ,在发送 AC时将其设为 '0,;对于 FirstPacket 字段, 在发送第一个数据分組时将其设为 '1' , 在发送其余数据分组时将其设 为 '0' ; 对于 LastPacket字段, 在发送最后一个数据分组时将其设为 'Γ , 在 发送其余数据分组时将其设为 '0' ; Offset字段用于确定 SC的起始发送时间 Τ, T是以时隙为单位表示的系统时间,它满足关系式 T mod 256=Offset;由于当 SC 中同时有同步休眠包与非休眠包时, 同步休眠包放在前面, 非休眠包放在后面, 层分组的分界, 其中休眠状态 MAC层分組除最后一个分组而外, 其它的分组的 该字段都置为 0, 最后一个休眠状态 MAC层分组的该字段置为 1 , 非休眠状态 MAC层分组的该字段也置为 1。 如图 2所示。
在 HRPD网络与异系统互操作时, 比如与 LTE或 Wimax等,为了使移动终 端 AT在 HRPD网时先获得异系统的邻区信息以便辅助 AT快速扫描异系统, AN会发送异系统邻区消息, 该消息在控制信道上传送。 该消息可在非休眠包中 传送, 一般不会在休眠包中传送, 也可在异步包 AC中传送。 发明人在实现本发明的过程中发现现有技术至少存在如下问题:
异系统邻区消息在非休眠包中传送的情况下, 第一, 当 AT需要接收异系统 邻区消息或从快速配置消息中发现需要更新异系统邻区消息时, 需要监听整个 SC包嚢, 并需要在 MAC层解包将净荷提交给上层协议并由上层协议解析后才 能获知该 SC包嚢中有无异系统邻区消息,造成处理资源浪费,比较费电;第二, 当 AT从快速配置消息中获知仅需要更新扇区参数消息时, 由于不能识別 SC包 嚢中是否含有异系统邻区消息, 而不得不把无需更新的异系统消息也接收下来, 并在送至上层解析后发现不用更新再丢弃, 造成处理资源浪费, 比较费电; 第 三, 当从快速配置消息中获知仅需要更新异系统邻区消息时, 需要将净荷提交 至上层, 并由上层解析后将其它无需更新的消息丢弃, 造成处理资源浪费, 比 较费电。

具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。 实施例一:
如图 3所示, 为本发明实施例方法流程图:
S301、 在控制信道同步包嚢的同步休眠包包头中标识出该同步包嚢是否包 含异系统邻区消息;
具体的, 本发明实施例可以将 MAC层分组包(休眠包也是一种 MAC层分 組包) 包头中 2bit的保留字段拿出 lbit来标识异系统邻区信息, 如表一所示, 同时可以规定在同步休眠包的包头中设置本同步包囊中是否含有异系统邻区消 息的信息, 比如该字段置 0表示本包嚢中没有异系统邻区消息, 置 1则表示有。 示意图如图 4所示。 本实施例不涉及对非休眠包本 bit位的设置, 设为 0或 1都 可以, 为了方法的简便, 可以也规定为与同步休眠包的设置一致, 本发明实施 例在此不做限制。
、 本发明实施例定义的 MAC层分组包头的格式
Figure imgf000011_0001
对于同步包嚢中仅有单独的同步休眠包的情况 (即 FirstPacket=l , LastPacket=l ) , 该 bit位置 0或置 1都没有关系, 因为单包只可能是同步休眠 包, 而异系统消息包一般位于非休眠包中。 为了具体实施的简便, 可以规定此 种情况下, 都置为 0, 即与表示后面没有异系统邻区消息。
对本实施例还可以变形为仅规定同步休眠包的第一个 MAC层分组包头中 相应比特位表示为该同步包嚢中有无异系统邻区消息, 当然还可以变形为规定 同步休眠包的最后一个 MAC层分组包头中相应比特位表示为该同步包嚢中有 无异系统邻区消息。在这种方法下,其它没有表示含义的 MAC层分组包头中的 相应比特位置 0或置 1都没有关系, 为了方法的简便, 可以规定此种情况下, 与表示含义的 MAC层分组的设置一致。
S302、 将所述经过 MAC协议封装后的控制信道同步包嚢发送给移动终端。 移动终端收到所述控制信道同步包嚢后, 就可以在 MAC层识别该 SC包嚢 中是否包含异系统邻区消息。
通过本发明实施例,可以使终端从 MAC层获知同步包囊中是否包含异系统 邻区消息,避免需要提交到上层协议并由上层协议解析后才能获知该 SC包囊中 是否有异系统邻区消息, 从而提高终端效率, 节省终端耗电量。
实施例二:
如图 5所示, 为本发明实施例方法流程图,
本发明实施例二是针对 SC包囊中的同步非休眠包的包头进行定义。将异系 统邻区消息包放在非休眠包的最后, 并对与其相邻的包作标识, AT可从与异系 统邻区消息包相邻的那个非休眠包获知有无异系统邻区消息, 如果确定有异系 统邻区消息, 还可确定所述异系统邻区消息包的具体位置。
具体步骤可以如下:
S501、 将异系统邻区消息包放置在控制信道同步包嚢非休眠包的最后位置; 由于异系统邻区消息放在同步包囊中, 一般是放在非休眠包中, 这样, 它 既可能单独与休眠包放在一起, 也可能是与休眠包以及其它非休眠包一起, 无 论哪种情况都不会出现异系统邻区消息包单独构成同步包嚢, 因此可规定将异 系统邻区消息包放在同步包嚢中的最后的控制信道 MAC分组中。
S502、 将与前述异系统邻区消息包相邻的非休眠包标识为异系统邻区消息 包; 与前述实施例一中的方法类似, 通过利用 MAC层分组包包头的保留字段, 新增标识信息, 例如 "OtherRATNeighborList相关信息"字段来标识出异系统邻 区消息包, 并同时利用其来确定非休眠包中其它非休眠包与异系统邻区消息包 的分界, 具体的, 可以将非休眠包中除异系统邻区消息包以外的其它非休眠包 的该字段都置为 0 (表示不是异系统邻区消息包, 当然也可以作其他标识, 本发 明实施例不做限制) , 但是, 上述其它非休眠包的最后一个分组若其后有异系 统邻区消息包, 则将该包的该字段置 1。 而异系统邻区消息包的该字段也置 1 , 示意图如图 6所示。 通过这种方式, 可以标识出其他非休眠包和异系统邻区信 息包的分界(如附图 6 中的其他非休眠包和异系统邻区信息包中间的虚线) , 从而定位出异系统邻区信息包的位置。
S502,、 (图中未示出)如果非休眠包中仅有异系统邻区消息包, 则可以在 休眠包中的最后一个包的包头将该包标识为异系统邻区消息包, 即可以将该字 段置 1。 而异系统邻区消息包的该字段也置 1 , 示意图如图 7所示。
S503、 将所述经过 MAC协议封装后的控制信道同步包囊发送给移动终端。 移动终端收到所述控制信道同步包嚢后, 就可以在 MAC层识别该 SC包嚢 中是否包含异系统邻区消息, 并且可以进一步确定异系统邻区消息包的位置。
通过本发明实施例,可以使终端从 MAC层获知同步包嚢中是否包含异系统 邻区消息, 并能进一步确定其位置, 避免需要提交到上层协议并由上层协议解 析后才能获知该 SC包嚢中是否有异系统邻区消息, 从而提高终端效率, 节省终 端耗电量。
本实施例还可以变形为将异系统邻区消息包插入在非休眠包的头部, 即紧 接在休眠包的后面。 此时可规定从异系统邻区消息包的包头获知后面有无其它 的非休眠包。 即与前述图 5中的实施方式的设置恰相反, 在此不再赘述。 通过变形后的实施例,可以使终端从 MAC层同步包嚢中获知是否包含其它 除了异系统邻区消息以外的非休眠包, 在仅需要更新异系统邻区消息的情况下, 就可以不用接收后续的其它非休眠包, 达到省电的目的。
本实施例还可以变形为将异系统邻区消息包插入在非休眠包的头部, 即紧 接在休眠包的后面。 此时可规定 MAC层分组包头的 "OtherRATNeighborList相 关信息" 表示本包是否为异系统邻区消息包, 对于 AN 而言, 若本包的内容是 异系统邻区消息, 则该比特位置 1 , 若不是则置 0。 当然也可以规定为 MAC层 分组包头的 "OtherRATNeighborList相关信息"表示本包是否为异系统邻区消息 且将且异 系 统邻 区 消 息 包的前一 包的 MAC 层分组 包头 的 "OtherRATNeighborList相关信息" 表示下一包是否为异系统邻区消息。
通过变形后的实施例,可以使终端从 MAC层同步包嚢中获知是否包含异系 统邻区消息,在无需更新异系统邻区消息的情况下, 在 MAC层就能获知是否含 有异系统邻区消息, 避免提交到上层解析而费电。
实施例三:
本发明实施例三可以充分利用 MAC层分组包包头中 2bit的保留字段, 即, 与实施例一中的方法类似, 利用 1个 bit来标识出该同步包囊是否包含异系统邻 区消息, 利用另外一个 bit来标识出非休眠包中异系统邻区信息包位置。 具体设 置方法与前面实施例的描述类似, 在此不再赘述。
通过本发明实施例, 可以充分利用保留字段, 在不增加开销的前提下, 使 得是解析更方便。
实施例四:
本发明实施例还可以通过选择某一空闲的子同步包来传送所述异系统邻区 消息。 由于子同步包是 HRPD协议中增加 MAC协议为了支持 PTT( Push To Talk ) 組呼对讲业务进行快速寻呼而定义的, 因此一般把寻呼周期设为 64时隙, 寻呼 周期的理论值可设为 4/8/16/32/64/128Z256等时隙, 每时隙的时长为 5/3毫秒。
子同步包的资源有很多 , 满足 T mod 4 = offset且 T mod 256≠ offset的时隙 均可, 即除了 SC而外每 4个时隙就有一个子同步包的资源, 但是由于寻呼常用 周期为 64个时隙, 即以 Offset = 2为例, 即只有编号为 66、 130、 194的时隙, 因此有很多子同步包的资源未发送子同步包, 鉴于此可以利用空闲的子同步包 的资源发送异系统邻区消息, 并在确定的位置发送,便于 AT在需要接收和更新 时仅接收该子同步包位置的 MAC层分组即可,可以节省因误接收其它数据包而 造成的电力耗费。
可以规定在控制信道中的 [T + 16] mod 256 = offset的 T时隙发送异系统邻区 消息, 其中 Τ是以时隙为单位的 CDMA系统时间。 这里选取 16是因为控制信 道 MAC层分組根据协议中的包格式在物理层最少都需要 4个时隙才能传完,而 物理层规定每 4个时隙调度一次, 因此需要 4*4=16个时隙, 当然这是较佳的实 施例, 还可以选择 20\24\28\32...60都可以; 当然也可以取 12, 但必须规定 AN 的物理层只传 3个时隙; 同理也可以取 8,但需要规定 AN的物理层只传 2个时 隙。
通过本发明实施例, 可以实现通过子同步包传送异系统邻区消息给终端, 并在确定的位置发送, 便于 AT在需要接收和更新时仅接收该子同步包位置的 MAC层分组即可, 从而可以节省因误接收其它数据包而造成的电力耗费。
实施例五:
本发明实施例还可以通过异步包 AC传送异系统邻区消息。具体的,可以规 定在控制信道中的 [T + 15] mod 256 = offset的 T时隙发送异系统邻区消息,其中 T是以时隙为单位的 CDMA系统时间。 这里选取 15是考虑了物理层 16个时隙 传完和避开子同步的位置这两个因素。 当然这是较佳的实施例, 还可以选择 17/18/ 19/21/22/23/25/26/27...63都可以; 当然可以取 14\13 , 但必须规定 AN的 物理层只传 3个时隙; 同理也可以取 7\6\5, 但需要规定 AN的物理层只传 2个 时隙。
通过本发明实施例, 可以实现通过确定位置的异步包传送异系统邻区消息 给终端,便于 AT在需要接收和更新时仅接收该异步包位置的 MAC层分组即可, 从而可以节省因误接收其它数据包而造成的电力耗费。 本发明实施例还提供了相应的指示异系统邻区信息的装置。
