Processing apparatus and method for network indication and communications system
A processing apparatus and method for network indication and a communications system in a procedure of RC-IWK. The processing method includes: a base station determines whether UE context release indication contains information on a cause of release indicating that a traffic of a UE is steered from the LTE to the WLAN, when the UE context release indication transmitted by an MME; and initiates a connection reconfiguration procedure to the UE so that the UE is kept in a connected state, in a case where the UE context release indication contains the information on the cause of release indicating that the traffic of the UE is steered from the LTE to the WLAN. Hence, a case, for example, where the UE not expecting to use the LTE is steered to the LTE system again, will not occur.
