标题[问题] 802.16 admitted QoS Parameter Set 看不懂解释
时间Wed Jul 26 04:06:26 2006
老实说小弟的英文不是很溜,
但自觉还可以懂规格书上说的意思,
就算不完全正确也不会差太多,
前几天meeting时老师指着规格书中的一段说:
"我觉的这和你说的感觉怪怪的",
顿时害我不知如何是好,
因此想烦请各位先进们帮我看看到底是怎样,
在802.16-2004规格书第224页中admitted service flows中提到:
A service flow that has resources assigned to its AdmittedQoSParamSet, but
whose resources are not yet completely activated, is in a transient state. It
is possible in some applications that a long-term reservation of resources is
necessary or desirable. For example, placing a telephone call on hold should
allow any resources in use for the call to be temporarily allocated to other
purposes, but these resources shall be available for resumption of the call
later. The AdmittedQoSParamSet is maintained as “soft state” in the BS;
this state shall be maintained without releasing the nonactivated resources.
Changes may be signaled with a DSC-REQ message.
我大概的解释如下:
某些上层应用须要经由一段时间後才开使启用,
举例来说一通电话被暂停住时,
其资源可以被挪为它用,
但之後又开始要讲电话时这些资源便须立即要回来,
因此AdmittedQoSParamSet就像一个BS的"软状态"(本人把它当成是逻辑状态),
此状态将维护非启用但不释放的资源,
若要更动须使用DSC-REQ讯息。
想请教各位先进,
不知小弟这样翻有无问题?
还有文中提到其资源可以被挪为它用不知是何意思,
亦烦请指点,
感谢。
