Description

基于MAP层协议的短消息单向提取方法 Extraction unidirectional short message based on MAP layer protocol

技术领域 FIELD

本发明涉及的是第二代移动通信网(GSM/GPRS)和第三代移动通信网(WCDMA/TD"SCDMA)中基于MAP协议的短消息(短信)传ilUa程中的的第三方采用非正常业务流程的单向提取方法。 背景技术 The present invention relates to a second generation mobile communication network (GSM / GPRS) and third generation mobile communication network (WCDMA / TD "SCDMA) in the third-party message-based non-MAP protocol (SMS) transmission process of ilUa extraction unidirectional normal business process. bACKGROUND oF tHE INVENTION

随着GSM/GPRS移动通信絲的发展,短信业务正在为用户提供越細多的服务。 With the development of GSM / GPRS mobile communications wire, SMS business is to provide users with finer and more services. 对于短信信息的非正常业务繊下提取的要求也相应的出现。 For non-normal business requirements of the extracted message information in Xian correspondingly appears.

现有的短消息的第三方单向提取^是针对的是互连网络协议承载下的短消息,对于其他方式下短消息的第三方单向提取方法还没有涉及。 Third party conventional way to extract the short message is directed ^ is a short message protocol carries the interconnection network, for other ways to third unidirectional extraction method involves a short message yet. 短消息作为基本的增皿务汇聚于移动核心网络的交换设备上和网关交换设备并通过移动应用层协议(MAP)负载,在核心网设备间的信皿上传递。 As a short message on a switching device substantially increase traffic aggregation cuvette in a mobile gateway switching core network and mobile equipment and the application layer protocol (MAP) load on the transmission channel between the core network device dish. (参考相^bl^准:3GPPTS 23.040 3GPPTS 29.002 3GPP TS 24.011 , 3G TS 29.060)在不影响正常的业务,、以第三方的身份从信4^&上单向提取基于MAP协议的短消息在S^上是一种可行的方法。 (Reference phase quasi ^ ^ BL: 3GPPTS 23.040 3GPPTS 29.002 3GPP TS 24.011, 3G TS 29.060) does not affect the normal traffic to third unidirectional ,, identity extracted from the channel 4 ^ MAP protocol message based on S It is a feasible method on ^.

在正常短消息交互和传递皿下,提取设备是网络中具有信令点的设备,需要维护多层的协议状态机,并和源方或目标方在短消息承,议的M^层上交互信息, 这个a^严谨、复杂。 Under normal delivery and short message interaction dish, the extraction device is a network device having a signaling point, the need to maintain a multilayer protocol state machines, and a source or target and a short message in the bearing, the proposed interactive layer M ^ information that a ^ rigorous, complicated. 并不适合不参与业务目和信令交换的单向的短消息提取。 Not suitable way not involved in projects and short message service signaling exchange extraction.

虽然目前,移动网執GSM/GPRS /UMTS)中信4^&的协im测设絲术可以提供 Although, mobile network executive GSM / GPRS / UMTS) & CITIC 4 ^ im determination for co operation wires may be provided

对主要网络设备的有效性测im务,并不适合移动^ffl层协议(MAP)的短信的提取 Im measuring the effectiveness of the primary network traffic equipment is not suitable for extracting a mobile SMS ^ ffl layer protocol (MAP) of

需要。 need. 针对移动JSffl层协议(MAP)的短消息的提取方法还未出现,本发明的出现满足了短消息业务相关管理单颇于短消息的提取方法的需求。 Extraction method for a mobile JSffl layer protocol (MAP) of the short message is yet to come, the present invention satisfies the occurrence of short message service management unit related to the extraction method is quite short message needs.
