一种发送短消息的方法 51*置
技术领域
本发明涉及通信技术领域， 尤其涉及发送短消息的方法及装置。 背景技术
SMS(Short Message Service, 短消息业务)成为一些无线手持设备的必备 功能， 目前， GSM 网络和 WCDMA网络支持短消息通过移动网 CS(Circuit Switch, 电路交换） 域或 PS(Packet Switch, 分组交换） 域发送或接收， 即分 别通过 CS域的 MSC(Mobile Switching Center, 移动交换中心)或 PS域的 SGSN(Serving GPRS Support Node, 服务 GPRS支持节点)承载。 发送短消息 时， 无线手持设备通过 CS或 PS域发送短消息， 然后通过不同的消息与网 络的相应实体进行交互， RNC(Radio Network Controller, 无线网络控制器） 根据从无线手持设备收到的消息， 将短消息发送到 MSC或者 SGSN， 然后 MSC或者 SGSN将短消息发送到短消息中心 SMC。 当无线手持设备的 CS 域或 PS域正在进行业务时， 即无线手持设备被分配了业务信道， 则无线手 持设备发送的短消息通过业务信道发送； 当无线手持设备的 CS域或 PS域没 有进行业务时， 即无线手持设备没有被分配业务信道时， 则无线手持设备通 过信令信道发送的短消息。当某个无线手持设备的 CS域或 PS域开始进行业 务时， RNC与 MSC或 SGSN之间需要建立相应的 Iu-CS或 Iu-PS接口连接； 当某个无线手持设备的 CS域或 PS域业务结束并延迟一定时间后， RNC与 MSC或 SGSN之间相应的 Iu-CS或 Iu-PS接口需要释放。
无线手持设备发送短消息时， 可能 Iu-PS接口已经存在， 但短消息发送 缺省通过 CS域， 导致 RNC与 MSC之间为发送短消息要频繁建立和释放 Iu-CS接口连接， 而不能利用已有的 Iu-PS接口连接， 导致浪费网络资源。 发明内容
