Abstract

A small data sending method and system and User Equipment (UE) are provided. The method includes that a server sends small data for a group of UE to an interworking gateway; the interworking gateway determines a broadcasting mode of sending the small data, and sends the small data to a target UE group by using the broadcasting mode; UE which received the small data in the target UE group returns a response message. By determining the sending mode of the received small data through the interworking gateway, small data can be simultaneously sent to multiple UE in a 3GPP network, thereby optimizing a sending process and reducing network resources used in the sending process.

Claims

1. A small data sending method, comprising:

sending, by a server, small data for a target User Equipment (UE) group to an interworking gateway;

determining, by the interworking gateway, a broadcasting mode of sending the small data, and sending the small data to the target UE group using the broadcasting mode; and

returning, by UE which received the small data in the target UE group, a response message.

2. The method according to claim 1, wherein the small data is data which has a data size not more than 1K bytes, and the small data comprises one or more of followings:

a group Identifier (ID) of the target UE group, a target area ID and a data type ID;

wherein the target area ID is for indicating an area where the target UE group is, and the data type ID is for indicating that the data is the small data.

3. The method according to claim 1, wherein determining, by the interworking gateway, the broadcasting mode of sending the small data comprises:

determining, by the interworking gateway, to send the small data by broadcasting through a Multimedia Broadcast Multicast Service (MBMS), a Cell Broadcast Service (CBS) or System Information (SI) according to one or more of following information;

network deployment, subscription information, server indication, and local policy information.

4. The method according to claim 1, wherein when the interworking gateway sends the small data to the target UE group through an MBMS, sending, by the interworking gateway, the small data to the target UE group using the broadcasting mode comprises:

sending, by the interworking gateway, the small data to the UE in the target UE group through a Broadcast Multimedia-Service Centre (BM-SC) via an MBMS process.

5. The method according to claim 1, wherein when the interworking gateway sends the small data to the target UE group through a CBS, sending, by the interworking gateway, the small data to the target UE group using the broadcasting mode comprises:

sending, by the interworking gateway, the small data to an area where the target UE group is through a Cell Broadcast Centre (CBC).

6. The method according to claim 1, wherein when the interworking gateway sends the small data to the target UE group through SI, sending, by the interworking gateway, the small data to the target UE group using the broadcasting mode comprises:

sending, by the interworking gateway. the small data to a base station through a Mobility Management Entity (MME) or a Service GPRS Support Node (SGSN); and

sending, by the base station, the small data through broadcasting to the UE in the target UE group.

7. The method according to claim 1, wherein returning, by the UE which received the small data in the target UE group, the response message comprises:

returning, by the UE, the response message to a base station after the UE which received the small data in the target UE group determines that the small data is data needed by the UE itself.

17. The method according to claim 2, wherein returning, by the UE which received the small data in the target UE group, the response message comprises:

returning, by the UE, the response message to a base station after the UE which received the small data in the target UE group determines that the small data is data needed by the UE itself.

18. The method according to claim 3, wherein returning, by the UE which received the small data in the target UE group, the response message comprises:

returning, by the UE, the response message to a base station after the UE which received the small data in the target UE group determines that the small data is data needed by the UE itself.

19. The method according to claim 4, wherein returning, by the UE which received the small data in the target UE group, the response message comprises:

returning, by the UE, the response message to a base station after the UE which received the small data in the target UE group determines that the small data is data needed by the UE itself.

20. The method according to claim 5, wherein returning, by the UE which received the small data in the target UE group, the response message comprises:

returning, by the UE, the response message to a base station after the UE which received the small data in the target UE group determines that the small data is data needed by the UE itself.

8. A small data sending system, comprising a server, an interworking gateway and User Equipment (UE);

wherein,

the server is configured to send small data for a target UE group to the interworking gateway;

the interworking gateway is configured to determine a broadcasting mode of sending the small data, and send the small data to the target UE group using the broadcasting mode;

the UE is one in the target UE group and is configured to return a response message after receiving the small data.

9. The system according to claim 8, wherein the small data is data which has a data size not more than 1K bytes, and the small data comprises one or more of followings:

a group ID of the target UE group, a target area ID and a data type ID;

wherein the target area ID is for indicating an area where the target UE group is, and the data type ID is for indicating that the data is the small data.

10. The system according to claim 8, wherein the interworking gateway is configured to determine that the small data is sent by broadcasting through a Multimedia Broadcast Multicast Service (MBMS), a Cell Broadcast Service (CBS) or System Information (SI), according to one or more of following information:

network deployment, subscription information, server indication, and local policy information.

11. The system according to claim 8, wherein the interworking gateway is configured to send the small data to the UE in the target UE group through a Broadcast Multimedia-Service Centre (BM-SC) via an MBMS process.

12. The system according to claim 8, wherein the interworking gateway is configured to send the small data to an area where the target UE group is through a Cell Broadcast Centre (CBC).

13. The system according to claim 8, further comprising a Mobility Management Entity (MME)/Service GPRS Support Node (SGSN) and a base station;

wherein,

the interworking gateway is configured to send the small data to the base station through the MME/SGSN;
