Elementary procedure packet switeched mobility management
主要关注以下几个test case
1、PS attach / rejected / PS services not allowed in this PLMN
由于当前PLMN不允许提供GPRS服务,从而拒绝PS附着请求。MS应该删除RAI, P-TMSI, P-TMSI signature以及GPRS 封装key sequence number,并且设置GPRS更新状态为GU3 ROAMING NOT ALLOWED。并且MS需要存储PLMN ID到FPLMN list中,一个处于MS mode C状态的MS应该执行PLMN选择,而不是cell 选择。一个处于MS mode A或B并且在network operation mode II or III状态的MS仍然在网络中保持IMSI attach。
测试目的是监测UE对于NW拒绝attach的反应行为。
测试步骤共19步。
2、PS detach / rejected / PS services not allowed in this PLMN
如果当前PLMN不允许提供GPRS服务,从而NW发起执行PS detach过程,则UE应该删除所存储的任何 RAI, P-TMSI, P-TMSI signature, and PS ciphering key sequence number 并把PS更新状态设置为 GU3 ROAMING NOT ALLOWED并改变状态为 GMM-DEREGISTERED。同时需要把PLMN ID加入FPLMN列表。
如果UE处于mode A而网络处于mode I,则应该把T3212设置为初始值并重启,如果它不在运行。并且仍然为CS服务保持IMSI的attach。
测试目的:测试网络发起PS detach procedure时UE的行为,Proc2是测试处于mode A的UE和NW operation I下网络发起PS detach procedure时UE的行为。
3、Routing area updating / rejected / PS services not allowed in this PLMN
如果当前PLMN不允许GPRS服务,从而NW发起拒绝RAU过程,则UE应该删除存储的 RAI, P-TMSI, P-TMSI signature, and PS ciphering key sequence number,并设置PS更新状态为 GU3 ROAMING NOT ALLOWED,并在FPLMN中存储 PLMN ID,并且不能删除PLMN表。
UE应该对应更新类型和UE mode,NW mode 执行如下行为,
1) UE is in UE operation mode C
UE shall perform a PLMN selection instead of a cell selection.
2) UE is in UE operation mode A, update type = periodic updating and Network is in network operation mode I
UE shall set the timer T3212 to its initial value and restart it, if it is not already running.
3) UE is in UE operation mode A and Network is in network operation mode II.
UE shall be still IMSI attached for CS services in the network.
测试目的:监测NW因为GPRS服务不允许,拒绝RAU过程之后,UE的行为。也分为test proc1和proc2
4、Combined routing area updating / rejected / PLMN not allowed
如果当前PLMN不允许,NW拒绝一个combined RAU过程,则UE应不执行combined GPRS attach,switched on in the same location area or PLMN, except when the PLMN identity is equal to the HPLMN.并删除存储的RAI, PS-CKSN, P-TMSI, P-TMSI signature, TMSI CKSN和 LAI,并且存储该PLMN到FPLMN。接收到RAUR消息的MS需要停止计时器T3330,进入MM IDLE状态。
问题:UE operation mode和NW operation Mode是什么概念,
UE operation mode分为A、B、C? NW operation Mode分为I,II,III?
