The present invention proposes a new method, a network device, and a terminal device of paging a terminal device in a communication system. The receiving a paging initiation present invention determines the paged object based on the group ID and/or the device ID of the paged terminal device, further, defines a specific paging occasion for the terminal device having group function; at the specific paging occasion paging message comprising the group ID and/or the device ID of the paged terminal device is sent; further, paging reason is inserted into the paging message; wherein the terminal device receives the paging message at the specific paging occasion defined by the system; and further reads the paging reason and responds accordingly to complete the paging procedure after the group ID and/or the device ID of its own is read. This paging mechanism of this invention solves the problem of paging determining a paging a group of terminal devices. It can meet the requirement of paging a specific or a group of terminal devices. The paging efficiency is thereby improved, and no negative impact on the paging of the current network terminal device is introduced.

Discloses is a gateway, base station, communication network and synchronization method thereof. The method comprises: at time T1, sending from the gateway to the base stations a synchronization request signal; at time T2, receiving by the base stations the synchronization request signal; at time T3, sending from the base stations to the gateway the synchronization response comprising the times T2 and T3; at time T4, receiving by the gateway the synchronization response signals; and calculating for the base stations a mapping relationship between the time system of the gateway and the time system of the base station is calculated based on the times T1, T2, T3 and T4. With the configuration and method proposed in present invention, it can be avoided the problem that accurate synchronization between the gateway and the base stations can not be reached for MBMS data packets in LTE because of path delay and jitter error, so that every base station can specify the same transmitting time for MBMS data packets to guarantee that UE could implement correct RF combining.

The present invention is related to integrated multi-datastream transmission technology, more particularly, to integrated multi-datastream modulation technology. According to one aspect of the present invention, there is provided a modulation equipment (10), including: a symbol integration means (101), configured to combine a first bit stream with a second bit stream to form a symbol to be modulated; a symbol mapping means (102), configured to map the symbol to be modulated into a QAM modulation symbol according to a set of predetermined mapping rules; wherein, in the set of predetermined mapping rules, multiple constellations corresponding to any first bit stream are located in at least two quadrants in the constellation diagram, while multiple constellations corresponding to any second bit stream are located in at least two quadrants in the constellation diagram. The integrated transmission of a first service data and a second service data (e.g., unicast service data and MBMS data) may be supported and has a better performance than the prior art especially in single cell scenario by using the method, equipment and device in the present invention.
