请问GMMSM中的PS Handover Capability是什么意思呢？

爱卫生

根据TS24.008的说明如下：

PS Handover Capability (1 bit field) This field indicates whether the mobile station supports the PS Handover. The PS Handover Capability applies to all RATs and modes indicated as supported in this information element.

Bit 0 The mobile station does not support the PS Handover.

1 The mobile station supports the PS Handover。

也就是说这个字段是指示MS是否支持PS Handover这个信令流程。该流程在TS43.129中定义。

PS Handover这个信令流程在TS23.060里是这么说的：The PS Handover procedure is used to handover an MS with one or more packet flows from a source cell to a target cell. The source and target cells can be located within either the same BSS (Intra BSS HO), different BSSs within the same SGSN (Intra SGSN HO) or belonging to different SGSNs (Inter SGSN HO), or systems with different radio access types (Inter RAT HO, Inter mode HO).

也就是带业务情况下在两个BSC负责的两个小区间做切换。不涉及到3G。如果是2G到3G的切换，规范里不叫PS Handover，而是叫做Inter-RAT(Radio Access Technology)。但PS Handover这个流程现网是不支持的。
