Abstract

The invention proposes a method and device for aggregating a plurality of service data from a terminal equipment. A first network device in a radio access network encapsulates a plurality of service data from a machine terminal equipment into a non-access stratum data packet, performs a transmission process on the non-access stratum data packet to generate a processed signal and transmits the processed signal. The signal is forwarded by a base station to a second network device in a core network. The second network device recovers the data packet from the signal, extracts the plurality of service data from the data packet and then transmits the plurality of service data respectively to a corresponding destination server. A signaling overhead and thus radio resources in a radio access network can be saved, and preferably a period of time for a terminal equipment to wait for a feedback can also be shortened.
