Description

补充业务的实现方法、 LTE网络***、 移动终端 技术领域
本发明涉及通信技术领域,特别涉及补充业务的实现方法、 LTE网络***、 移动终端。
背景技术
LTE ( Long Term Evolution, 长期演进)技术是从 3G ( 3rd-Generation, 第 三代移动通信技术)向 4G ( 4th-Generation, ***移动通信技术)演进的主 流技术,它改进并增强了 3G通信技术的空中接入技术,采用 OFDM( Orthogonal Frequency Division Multiplexing , 正交频分复用 ) 和 MIMO ( Multiple- Input Multiple-Output, 多入多出)作为其无线网络演进的唯一标准。 在 20MHz频谱 带宽下能够提供下行 100Mbit/s与上行 50Mbit/s的峰值速率, 改善了小区边缘 用户的性能, 提高小区容量和降低***延迟。
LTE网络是全分组交换网络, 由于目前 LTE终端以及网络部署初期网络 性能等因素的影响, 当用户在使用 LTE 网络发生语音业务请求的时候, 需要 将话路由 LTE网络切换到 2G/3G网络实现语音业务请求, LTE网络本身无法 提供 CS ( Circuit Switch, 电路交换)域业务, LTE PS ( Packet Switch, 分组交 换)域可以提供短信等数据业务。 所述由 LTE网络切换到 3G/2G网络可采用 CSFB ( Circuit Switched Fallback, 电路域回落)或 SRVCC(Single Radio Voice Call Continuity, 单无线模式语音呼叫连续性)方案来提供语音业务。
补充业务分为与呼叫相关的补充业务以及与呼叫无关的补充业务。所述与 呼叫相关的补充业务是指必须在通话过程中进行的业务,如呼叫保持、 多方通 话等业务; 所述与呼叫无关的业务是指可以不在通话过程中进行的业务, 如 USSD ( Unstructured Supplementary Service Data, 非结构 4匕补充数据业务)、 呼 叫转移查询、 呼叫转移设置、 呼叫等待设置等业务。
目前 LTE 网络制式下无法直接支持 CISS ( Call Independent Supplement Service, 与呼叫无关的补充业务)业务, 但是用户在使用过程中会经常使用这 些业务, 而如果在使用 CISS时通过 CSFB回落到 3G/2G网络进行, 制式间的 切换会给终端以及网络性能带来^艮大开销。
例如, 如果通过 CSFB从 LTE网络回落到 3G/2G网络, 具体回落过程是 UE ( User Equipment, 用户设备)先向 LTE网络发起扩展业务请求, 然后网络 响应请求后触发回落流程, 在上述消息交互过程中存在一些不确定性, 例如 LTE网络链路质量差或者网络响应太慢等, 都可能导致 CISS业务延时太长, 甚至引起 CISS业务失败, 同时还需要对 UE设备正在 LTE网络中进行的 PS 域的数据业务进行处理, 可以将所述 PS域的数据业务暂时挂起, 或者切换到 3G/2G网络进行。
由于 CISS业务一般都是短暂的、 非连续性的业务, 通过 CSFB来实现, 代价比较大, 而且会影响其它 PS域的业务, 降低了终端本身的性能, 而呼叫 转移设置、 呼叫等待设置、 USSD等 CISS业务都是用户经常用到的功能, 不 能不加以支持。 目前对于 LTE终端的 CISS业务的实现, 并没有明确的方法。
上述现有技术的方法中存在的不足之处在于: 由于 LTE网络无法提供 CS 域业务, LTE终端在 LTE网络无法支持 CISS业务, 通过 CSFB回落到 3G/2G 下来进行 CISS, 由于制式之间的切换会带来 4艮大的开销, 影响网络、 终端的 性能。
相关现有技术还可参考公开号为 US2012064884 (A1)的美国专利申请, 该专利申请公开了一种终端由 LTE网络通过 CSFB方法回落到其它网络, 完 成 CS域业务的方法。

具体实施方式
为使本发明的上述目的、特征和优点能够更为明显易懂, 下面结合附图对 本发明的具体实施方式做详细的说明。在以下描述中阐述了具体细节以便于充 分理解本发明。但是本发明能够以多种不同于在此描述的其它方式来实施, 本 领域技术人员可以在不违背本发明内涵的情况下做类似推广。因此本发明不受 下面公开的具体实施方式的限制。
图 1是本发明实施例提供的一种补充业务的实现流程示意图。
如图 1所示, 所述补充业务的实现方法包括:
步骤 S110, 接收来自移动终端的 Uplink NAS Transport (上行 NAS传输 ) 消息。
在本发明的实施例中, 当移动终端 Combined Attach (联合附着)到 LTE网 络后, 向网络发送 CISS业务请求, 终端与网络建立 PS域信令连接, 终端向 网络发送 Uplink NAS Transport消息。 网络侧接收来自移动终端的所述 Uplink NAS Transport消息。 步骤 S120, 解析所述 Uplink NAS Transport消息。
在本发明的实施例中, 可以根据其中的 NAS Message Container中消息的 PD ( Protocol Discriminator, 协议鉴别器状态) 字段判断所述 Uplink NAS Transport所携带消息是否为 SS ( Supplement Service, 补充业务 ) 消息。
步骤 S130 , 在基于所述 Uplink NAS Transport 消息的 NAS Message Container ( NAS消息容器)确定所述 Uplink NAS Transport所携带消息为 SS 消息时, 进行补充业务的处理。
在本发明的实施例中, 如果由解析的 NAS Message Container所携带消息 中的 PD值, 判断出所述消息是 SS消息时, 则进行相应的 CISS业务的处理。
具体地, 所述 SS消息为与呼叫无关的 CISS业务, 如呼叫转移设置、 呼 叫转移等待设置、 USSD业务等。
本领域的技术人员理解, LTE终端在 LTE网络下实现 CISS功能, 需要实 现 SS消息在 LTE网络的空口消息中的封装和解析。本发明的发明人发现, LTE 协议中 Uplink NAS Transport消息和 Downlink NAS Transport (下行 NAS传 输 ) 消息中的 NAS Message Container可以用来进行 SS消息的传递。
NAS( Non-Access Stratum,非接入层)协议处理 UE和 CN( Core Network , 核心网)之间信息的传输, 传输的内容可以是用户信息或控制信息, 如业务的 建立、 释放或者移动性管理信息。 NAS 消息的传输基于底层的 AS ( Access Stratum, #A2¾ F j¾* liI^\/i^ gg (^^^翁^ ¾下面的 AS协议结构, 与无线接.
代合作伙伴计划)协
Figure imgf000010_0001
如表 1所示, NAS Message Container消息中, 第一个八位字节 octetl中 存放的是 NAS Message Container的标示;第二个八位字节 octet2中存放的 NAS Message Container消息体的长度;后面的所有八位字节用来存放 NAS Message Container消息的内容。 目前 LTE协议中的 NAS Message Container主要携带 SMS( Short Messaging Service, 短消息业务) 消息。
m M^m^ w^编码方式是类似的, 消息的第一个字节都是由半 个字
Figure imgf000011_0001
由于 PD可以用来区分不同的协议模块,例如 SS消息的 PD值是 11 , SMS 消息的 PD值是 9 , 通过解析 PD就能判断出当前 NAS Message Container中携 带的是 SS 消息或者是 SMS 消息。 由此发送端就能将 SS 消息封装在 NAS Message Container消息中, 接收端通过解析 NAS Message Container所携带消 息中的 PD字段来识别当前携带的消息是 SS消息还是 SMS消息。
因此可以通过 LTE 网络下消息的封装和解析、 终端与网络的消息交互来 实现 LTE的 PS域的 CISS功能。
具体地, LTE网络下 SS消息的封装和解析包括: 终端和网络交互 SS消 息时, 终端可以将 SS消息封装在 Uplink NAS Transport消息的 NAS Message Container 中, 网络收到 Uplink NAS Transport 消息后解析 NAS Message Container内容, 判断如果是 SS消息就发送到 SS模块进行后续处理; 网络可 以将 SS消息封装在 Downlink NAS Transport消息的 NAS Message Container 中, 终端收到 Downlink NAS Transport消息后解析 NAS Message Container内 容, 判断如果是 SS消息就发送到终端 SS模块进行后续处理。
LTE网络下终端与网络的 SS消息交互过程包括: 终端发送 SS消息时, 终端通过 Uplink NAS Transport 消息将 SS 消息发送给 MME ( Mobile Managenment Entity , 移动管理实体), MME 通过 Uplink Unitdata (上行 Unitdata ) 消息将所述 SS消息发送给 MSC ( Mobile Switching Center, 移动交 换中心 ), MSC将所述 SS消息交给对应 SS模块进行处理; 网络发送 SS消息 时, SS模块将消息交给 MSC, MSC通过 Downlink Unitdata (下行 Unitdata ) 消息将所述 SS消息发给 MME, 终端收到 MME通过 Downlink NAS Transport 消息发送的所述 SS消息后, 将所述 SS消息后交由终端 SS模块进行处理。 本领域的技术人员理解,所述 SS消息也可以采用其他上行的 NAS传输消 息或下行的 NAS 传输消息进行封装和解析。 例如, 可以扩展为使用 Uplink Generic NAS Transport (上行通用 NAS传输 ) 消息和 Downlink Generic NAS Transport (下行通用 NAS传输 ) 消息进行封装和解析。

HLR/HSS 240中 HLR ( Home Location Register , 归属位置寄存器)是 GSM ( Global System of Mobile communication, 全球移动通讯***) ***的中 央数据库, 存放着所有归属用户的信息, 如用户的有关号码、 用户类别、 漫游 能力、 签约业务和补充业务等。 此外, HLR还存储着每个归属用户有关的动 态数据信息, 如用户当前漫游所在的 MSC/VLR地址(即位置信息 )和分配给 用户的补充业务。 HSS ( Home Subscriber Server, 归属用户服务器)是支持用 于处理调用、 会话的网络实体的主要用户数据库。 它包含用户配置文件、执行 用户的身份验证和授权、 并可提供有关用户物理位置的信息。
