高通NV6876的配置问题

NV Item NV Name NV Value UE Behavior
6876 Dual standby config items 0x00 dedicated_voice_subs
0x00 dedicated_data_subs
0x00 active_subs
0x00 priority_subs
0x05 1. Single_standby_pref
2. dual_standby-pref
3. x
4. x
5. DSDS -> WCDMA/GSM to GSM Tune away
6. DSDS -> No Tune away

以上是我查到的6876的NV的定义，哪位帮忙讲讲具体的含义，谢谢 了

NV 6878 –This NV controls the TA feature. If this octet is set to 1 TA feature ON. If this octet is set to 0 –tune-away feature OFF.

cm_ph_cmd_dual_standby_pref() with value of ‘standby_pref’ being SYS_MODEM_DS_PREF_DUAL_STANDBY (with TA) or SYS_MODEM_DS_PREF_DUAL_STANDBY_NO_TUNEAWAY (without TA)

兄弟啊，是NV6876，不是6878.
能讲讲6876吗

自己顶，有谁能帮忙讲讲这个NV的含义及配置方法?！
