Abstract

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.

Claims

1. A method of paging a terminal device in a communication system comprising network devices and terminal devices, wherein, the method comprises:

receiving, by the network device, a paging initiation message;

determining, by the network device, a paged terminal device;

determining, by the network device, a paging occasion;

sending, by the network device, a physical layer paging indication and a paging message at a time corresponding to the paging occasion, detecting, by the terminal device, the physical layer paging indication at the paging occasion;

receiving the paging message, by the terminal device, which detects the physical layer paging indication at the corresponding paging occasion.

2. A method according to claim 1, wherein the paging initiation message comprises the group ID and/or device ID of the paged terminal device, which is identified by its group ID or device ID;

the paging occasion is determined by the group ID of the terminal device;

the network device sends the group ID and/or device ID of the paged terminal device to the terminal device using the paging message;

the terminal device which receives the paging message checks if the paging message comprises its group ID and/or device ID.

3. A method according to claim 2, wherein the paging initiation message further comprises an area information of the paged terminal device;

and the network device determines a paging area in which the paging message is sent according to the area information of the paged terminal device; and

sends the physical layer paging indication and the paging message to the paging area only.

4. A method according to claim 1, wherein the paging initiation message further comprises a paging reason;

and based on the paging reason comprised in the paging initiation message, the network device further inserts the corresponding paging reason into the paging message, and informs the paged terminal device of the required operations; and

the terminal device, which detects its group ID or device ID in the paging message, further acquires the paging reason indicated in the paging message, and then performs required procedures based on the paging reason.

5. A method according to claim 4, wherein the paging initiation message is originated from upstream network devices;

the paging reason being call setup or uplink report;

if the paging reason is call setup, the terminal device initiating a procedure to set up connection with the network for call;

if the paging reason is uplink report, the terminal device feedbacking a uplink report.

6. A method according to claim 4, wherein the paging initiation message is originated from the operation and administration devices of the communication system;

wherein the paging reason is system information acquisition, the corresponding operation of the terminal device according to the paging reason being reading the system information.

7. (canceled)

8. A network device which sends paging message in the communication system, wherein the communication system comprises at least one terminal device with a group ID and a device ID, the network device comprises:

a receiver, for receiving a paging initiation message, which comprises the group ID and/or device ID of the paged terminal device;

an apparatus for determining paged terminal device, configured to determine a paged terminal device based on the paging initiation message, the paged terminal device being determined by its group ID or device ID;

an apparatus for calculating paging occasion, configured to calculate a paging occasion based on the group ID of the paged terminal device;

an apparatus for generating physical layer data, configured to generate a physical layer control message which comprises a physical layer paging indication;

an apparatus for generating paging message, configured to generate a paging message which comprises the group ID and/or device ID of the paged terminal device;

a transmitter, for sending the physical layer information and the paging message at a time corresponding to the paging occasion.

9. A network device according to claim 8, wherein, the paging initiation message received by the receiver further comprises a paging reason, and the apparatus for generating paging message further inserts the paging reason into the paging message.

10. A network device according to claim 9, wherein the paging initiation message received by the receiver is originated from an network device that locates upper level of the network device;

wherein the paging reason is setup call or uplink report.

11. A network device according to claim 9, wherein the paging initiation message received by the receiver is originated from the operation and administration devices of the communication system;

wherein the paging reason is system information acquisition.

12. A network device according to claim 8, wherein, the paging initiation message received by the network device further comprises an area information of the paged terminal device;

and the network device also comprises a paging area determing apparatus, which is configured to determine a paging area, in which the paging message is sent, according to the area information of the paged terminal device; and

according to the paging area exported by the paging area determing apparatus, the transmitter sends the physical layer information and the paging message to the paging area only.

13. (canceled)

14. A terminal device which comprises:

an apparatus for calculating paging occasion, configured to calculate a paging occasion;

a first receiver, for receiving a physical layer paging indication from a network device at the paging occasion;

a second receiver, for receiving a paging message after the first receiver receives the physical layer paging indication.

15. A terminal device according to claim 14, comprising:

an apparatus for identifying device identity, configured to identify the ID of the terminal device, including group ID and device ID;

an apparatus for detecting device identity, configured to detect if the paging message comprises the group ID and/or the device ID of the terminal device;

further, the apparatus for calculating paging occasion is for calculating the paging occasion based on the group ID of the terminal device.

16. A terminal device according to claim 14, comprising:

an apparatus for reading paging reason, configured to read the paging reason comprised in the paging message, when the apparatus for detecting device identity detects the group ID and/or the device ID of the terminal device;
