Abstract

Embodiments of the present invention relate to a method for establishing a bearer for a machine to machine service and a network transmission device, where the method includes: receiving a user plane resource establishment request message sent by an MTC device, where the user plane resource establishment request message includes at least one of MTC features, QoS requirements, a service indication request and a group identity; determining negotiated QoS parameters according to the user plane resource establishment request message; and establishing a transmission bearer with the MTC device according to the negotiated QoS parameters. The present invention provides a method for establishing a transmission bearer between a network and an MTC device.

First claim

What is claimed is:

1. A method for establishing a bearer for a machine to machine (M2M) service, comprising:
receiving, by a network transmission device, a packet data protocol (PDP) activation request message sent by a machine type communication (MTC) terminal requesting initiation of the M2M service, wherein the PDP activation request message has content including a group identity of a group of MTC terminals, and wherein the MTC terminal belongs to the group of MTC terminals that share common service features identified by the group identity;
determining, by the network transmission device, negotiated quality of service (QoS) parameters for the MTC terminal according to the group identity, an internet protocol (IP) address being allocated to the MTC terminal according to the received PDP activation request message;
sending, by the network transmission device, the negotiated QoS parameters and the IP address to the MTC terminal, so that a transmission bearer is established with the MTC terminal;
receiving, by the network transmission device, a protocol data unit (PDU) data packet from a MTC server, wherein the PDU data packet comprises indication information other than auxiliary information, and wherein the indication information is used to indicate that a service is a network-assisted mobile originated (MO) service; and
notifying, by the network transmission device, the indication information to the MTC terminal, wherein the indication information is used for the MTC terminal to establish a dedicated bearer based on initiative of the MTC terminal to obtain the auxiliary information from the MTC server,
wherein the auxiliary information comprises service trigger conditions, and the service trigger conditions are used for the MTC terminal to perform the M2M service initiation requesting when the MTC terminal judges that service trigger conditions are satisfied.

2. The method according to claim 1 ,
wherein the PDU data packet received from the MTC server includes the auxiliary information, and the auxiliary information includes the service trigger conditions; and
the method includes notifying, by the network transmission device, the MTC terminal of the auxiliary information so that the service trigger conditions included in the auxiliary information are used for the MTC terminal to perform the M2M service initiation requesting when the MTC terminal judges that service trigger conditions are satisfied.

3. The method according to claim 2 , wherein the notifying, by the network transmission device, the auxiliary information to the MTC terminal comprises:
sending, by the network transmission device, a paging message to the MTC terminal, wherein the paging message carries channel notification information indicating a downlink channel from which the MTC terminal is to read the auxiliary information.

4. The method according to claim 3 , wherein the PDU data packet further comprises the group identity, and
the sending, by the network transmission device, of the paging message to the MTC terminal comprises:
obtaining, by the network transmission device, a network group identity according to the group identity;
initiating, by the network transmission device, the paging message according to the network group identity; and
sending, by the network transmission device, the paging message to the MTC terminal.

5. The method according to claim 2 , wherein the service trigger conditions comprise a time window allowing service initiation and a location area allowing service initiation.

6. The method according to claim 1 , wherein the notifying, by the network transmission device, the indication information to the MTC terminal comprises:
sending, by the network transmission device, a paging message to the MTC terminal, wherein the paging message carries the indication information.

7. The method according to claim 6 , wherein the PDU data packet further comprises the group identity; and
the sending, by the network transmission device, a paging message to the MTC terminal comprises:
obtaining, by the network transmission device, a network group identity according to the group identity;
initiating, by the network transmission device, the paging message according to the network group identity; and
sending, by the network transmission device, the paging message to the MTC terminal.

8. The method according to claim 1 , wherein the service trigger conditions comprise a time window allowing service initiation and a location area allowing service initiation.

9. A network transmission device, comprising:
a memory;
a processor coupled to the memory, the processor configured to:
receive a packet data protocol (PDP) activation request message sent by a machine type communication (MTC) terminal requesting initiation of the M2M service, wherein the PDP activation request message has content including a group identity of a group of MTC terminals, and wherein the MTC terminal belongs to the group of MTC terminals that share common service features identified by the group identity;
determine negotiated QoS parameters for the MTC terminal according to the group identity; and

wherein an internet protocol (IP) address being allocated to the MTC terminal according to the received PDP activation request message, and the negotiated QoS parameters and the IP address are provided to the MTC terminal so that a transmission bearer is established with the MTC terminal,
a protocol data unit (PDU) data packet is received from a MTC server, the PDU data packet comprises indication information other than auxiliary information, and the indication information is used to indicate that a service is a network-assisted mobile originated (MO) service,
the MTC terminal is notified of the indication information, and the indication information is used for the MTC terminal to establish a dedicated bearer based on initiative of the MTC terminal to obtain the auxiliary information from the MTC server, and
the auxiliary information comprises service trigger conditions, and the service trigger conditions are used for the MTC terminal to perform the M2M service initiation requesting when the MTC terminal judges that service trigger conditions are satisfied.

10. The network transmission device according to claim 9 , wherein the PDU data packet received from the MTC server includes the auxiliary information, and the auxiliary information includes the service trigger conditions, and
the MTC terminal is notified of the auxiliary information, and the service trigger conditions included in the auxiliary information are used for the MTC terminal to perform the M2M service initiation requesting when the MTC terminal judges that service trigger conditions are satisfied.

11. The network transmission device according to claim 10 , wherein the notification of the auxiliary information to the MTC terminal comprises:
sending, by the network transmission device, a paging message to the MTC terminal, wherein the paging message carries channel notification information indicating a downlink channel from which the MTC terminal is to read the auxiliary information.

12. The network transmission device according to claim 11 , wherein the PDU data packet further comprises the group identity, and
the sending, by the network transmission device, of the paging message to the MTC terminal comprises:
obtaining, by the network transmission device, a network group identity according to the group identity;
initiating, by the network transmission device, the paging message according to the network group identity; and
sending, by the network transmission device, the paging message to the MTC terminal.
