Device and Method of Aggregating LTE System and WLAN
First Claim
1. A communication device for handling long-term evolution (LTE)-wireless local area network (WLAN) aggregation, comprising:
- a storage unit, for storing instructions of;
connecting to a base station (BS) via LTE communication;
detecting a radio link failure on the LTE communication;
stopping transmission/reception of at least one first LTE protocol data unit (PDU) via a WLAN in response to the radio link failure, if the WLAN is configured by the BS for the transmission/reception of the at least one first LTE PDU with the BS via the WLAN; and
keeping transmission/reception of at least one non-LTE PDU via the WLAN in response to the radio link failure, if the WLAN is not configured by the BS for the transmission/reception of the at least one first LTE PDU with the BS via the WLAN; and
a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
