Abstract

Embodiments of the present invention provide a method and device for transmitting data. The method includes: determining, after receiving a first message sent by a user equipment, whether first indication information is set, where the first indication information indicates that a server buffers downlink data to be sent to the user equipment; and when determining that the first indication information is set, retaining a signaling connection to the user equipment, and triggering the server that buffers the downlink data to send the downlink data to the user equipment. The method and device for transmitting data according to the embodiments of the present invention can save power of a user equipment.

Claims

1. A method for transmitting data, comprising:

determining, by a core network control entity, after receiving a first message sent by a user equipment, whether first indication information is set, wherein the first indication information indicates that a server buffers downlink data to be sent to the user equipment, the first indication is associated with a validity period of the downlink data, wherein the first message is a Tracking Area Update (TAU) message or a Routing Area Update (RAU) message; and

when the first indication information is determined to be set in the core network control entity, establishing a user plane bearer or a Packet Data Protocol (PDP) context, and triggering the server that buffers the downlink data to send the downlink data to the user equipment through the user plane bearer or the PDP context.

2. The method according to claim 1, wherein the establishing the user plane bearer comprises:

establishing of radio bearers that are between the user equipment and an eNodeB and are corresponding to all activated bearers of the user equipment, and establishing of S1 user plane connections between the eNodeB and a serving gateway and are corresponding to all activated bearers of the user equipment.

3. The method according to claim 1, wherein establishing the PDP context comprises:

establishing of radio bearers that are between the user equipment and an Radio Network Controller (RNC) and are corresponding to all activated PDP contexts of the user equipment, and establishing of Iu user plane connections between the RNC and an Serving General Packet Radio Service Support Node (SGSN) and are corresponding to all activated PDP contexts of the user equipment.

4. The method according to claim 1, wherein before the determining whether first indication information is set, the method further comprises:

receiving a context response message sent by a source core network control entity serving the user equipment; and

when the context response message comprises the first indication information, setting the first indication information.

5. The method according to claim 2, wherein before the determining whether first indication information is set, the method further comprises:

receiving a context response message sent by a source core network control entity serving the user equipment; and

when the context response message comprises the first indication information, setting the first indication information.

6. The method according to claim 1, the method further comprises:

When the validity period of the downlink data expires, deletes the first indication.

7. The method according to claim 1, the core network control entity comprises:

a Serving General Packet Radio Service Support Node (SGSN) or a Mobility Management Entity (MME).

8. A core network control entity comprising:

a processor; and

a memory coupled to the processor, the memory having processor-executable instructions stored thereon, which when executed causes the processor to implement operations including;

after receiving a first message sent by a user equipment, determining whether first indication information is set, wherein the first indication information indicates that a server buffers downlink data to be sent to the user equipment, the first indication is associated with a validity period of the downlink data, wherein the first message is a Tracking Area Update (TAU) message or a Routing Area Update (RAU) message;

when the first indication information is determined to be set in the core network control entity, establishing a user plane bearer or a Packet Data Protocol (PDP) context; and

triggering the server that buffers the downlink data to send the downlink data to the user equipment through the user plane bearer or the PDP context.

9. The core network control entity according to claim 8, wherein the establishing the user plane bearer comprises:

establishing of radio bearers that are between the user equipment and an eNodeB and are corresponding to all activated bearers of the user equipment, and establishing of S1 user plane connections between the eNodeB and a serving gateway and are corresponding to all activated bearers of the user equipment.

10. The core network control entity according to claim 8,

wherein establishing the PDP context comprises:

establishing of radio bearers that are between the user equipment and an Radio Network Controller (RNC) and are corresponding to all activated PDP contexts of the user equipment, and establishing of Iu user plane connections between the RNC and an Serving General Packet Radio Service Support Node (SGSN) and are corresponding to all activated PDP contexts of the user equipment.

11. The core network control entity according to claim 8, wherein the operations further include:

wherein before the determining whether first indication information is set,

receiving a context response message sent by a source core network control entity serving the user equipment; and

when the context response message comprises the first indication information, setting the first indication information.

12. The core network control entity according to claim 9, wherein the operations further include:

wherein before the determining whether first indication information is set,

receiving a context response message sent by a source core network control entity serving the user equipment; and

when the context response message comprises the first indication information, setting the first indication information.

13. The core network control entity according to claim 10,

When the validity period of the downlink data expires, deletes the first indication.

14. The core network control entity according to claim 8, the core network control entity comprises:

a Serving General Packet Radio Service Support Node (SGSN) or a Mobility Management Entity (MME).

15. A non-transitory computer readable storage medium storing one or more programs, wherein the one or more programs comprise an instruction, wherein when executed by a core network control entity, the instruction enables the core network control entity to implement the following operations:

after receiving a first message sent by a user equipment, determining whether first indication information is set, wherein the first indication information indicates that a server buffers downlink data to be sent to the user equipment, the first indication is associated with a validity period of the downlink data, wherein the first message is a Tracking Area Update (TAU) message or a Routing Area Update (RAU) message;

when the first indication information is determined to be set in the core network control entity, establishing a user plane bearer or a Packet Data Protocol (PDP) context; and

triggering the server that buffers the downlink data to send the downlink data to the user equipment through the user plane bearer or the PDP context.

16. The non-transitory computer readable medium according to claim 15, wherein the establishing the user plane bearer comprises:
