When the UE under RRC connection status under CCO mode from E-UTRAN systematic evaluation to GERAN system time, UE sets up from re-starting business after connection status becomes idle condition again, thus business can be caused to occur flash, and then affects user awareness.
When the UE under RRC idle condition under Reselection mode from E-UTRAN systematic evaluation to UTRAN system or GERAN system time, the UE under the RRC idle condition of E-UTRAN system can be regarded as following two kinds of situations:
1, UE only starts shooting and has residently arrived E-UTRAN network, does not initiate business.Now Reselection to other system on business and QoS without any impact;
2, the RRC connection of UE is set up, and is in connection status, when UE initiates in business procedure, and for a certain reason will by its Reselection to other system according to certain criterion eNB.Now need first by RRC Connection Release, UE is in RRC_IDLE state, and user can perceive the change of network, and the interrupt procedure of business, QoS is affected.
As can be seen here, in current practical application, when the UE of E-UTRAN is switched to different system cell under CCO mode and Reselection mode, the business caused due to the change of state can be there is and occur the situation that flash is broken even completely, thus increase cutting off rate, affect user awareness.
Summary of the invention
In view of this, main purpose of the present invention is the acquisition methods providing a kind of RIM information, and the UE that the method can reduce E-UTRAN is switched to conversation loss rate during different system cell.
In order to achieve the above object, the technical scheme that the present invention proposes is:
An acquisition methods for radio access network information management information, the method comprises the following steps:
A, in E_UTRAN system, Operation and Maintenance network element open preset RAN information management RIM acquisition of information switch;
