Abstract

A method, a machine to machine (M2M) terminal, an access point (AP), and a system for achieving a machine to machine service are provided. The method includes: determining an AP that supports the M2M service; establishing a communication connection to the AP; receiving service configuration information sent by the AP; and sending a service data report message to the AP according to the service configuration information, where the service data report message includes service data corresponding to the M2M service. The M2M terminal includes a determining module, a connection module, a first receiving module, and a first sending module. The AP includes a first determining module, a connection module, a first sending module, and a first receiving module. The system includes the M2M terminal, the AP, and the M2M server according to embodiments of the present invention.

First claim

What is claimed is:

1. A method for achieving a machine to machine (M2M) service, comprising:
determining a wireless access point (AP) that supports the M2M service by determining that a first service identifier that corresponds to the M2M service supported by an M2M terminal matches a second service identifier that corresponds to the M2M service supported by the AP when the second service identifier is received from the AP in a broadcast frame;
determining the AP that supports the M2M service by determining that the first service identifier matches the second service identifier when the second service identifier is received from the AP in response to a probe request message;
establishing a communication connection to the AP when the AP supports the M2M service;
receiving service configuration information sent by the AP; and
sending a service data report message to the AP according to the service configuration information,
wherein the service data report message comprises service data corresponding to the M2M service,
wherein after receiving the service configuration information sent by the AP, the method further comprises negotiating a data transmission mechanism with the AP according to the service configuration information, and
wherein sending the service data report message to the AP according to the service configuration information comprises sending the service data report message to the AP according to the service configuration information and the result of the negotiation with the AP about the data transmission mechanism.

2. The method according to claim 1 , wherein negotiating the data transmission mechanism with the AP according to the service configuration information comprises:
sending a resource request message to the AP, wherein the resource request message comprises initial service time and a service duration that are determined by the M2M terminal according to the service information in the service configuration information; and
receiving a resource response message sent by the AP in response to the resource request message, wherein the resource response message comprises initial service time and a service duration that are allocated by the AP for the M2M terminal according to the service information and the resource request message.

3. A method for achieving a machine to machine (M2M) service, comprising:
determining a wireless access point (AP) that supports the M2M service when the AP transmits a second service identifier that corresponds to the M2M service supported by the AP to an M2M terminal as a part of a broadcast frame and the second service identifier matches a first service identifier on the M2M terminal that corresponds to the M2M service supported by the M2M terminal;
determining the AP that supports the M2M service when the AP receives a probe request message comprising the first service identifier from the M2M terminal that matches the second service identifier;
establishing a communication connection to the M2M terminal that supports the M2M service;
sending service configuration information to the M2M terminal;
receiving a service data report message that is sent by the M2M terminal according to the service configuration information, wherein the service data report message comprises service data corresponding to the M2M service; and
receiving service information from an M2M server that supports the M2M service,
wherein the service configuration information sent to the M2M terminal comprises the service information,
wherein after sending the service configuration information to the M2M terminal, the method further comprises negotiating a data transmission mechanism with the M2M terminal according to the service information, and
wherein receiving the service data report message that is sent by the M2M terminal according to the service configuration information comprises receiving the service data report message that is sent by the M2M terminal according to the service configuration information and the result of the negotiation with the M2M terminal about the data transmission mechanism.

4. The method according to claim 3 , wherein negotiating the data transmission mechanism with the M2M terminal according to the service information comprises:
receiving a resource request message sent by the M2M terminal, wherein the resource request message comprises initial service time and a service duration that are determined by the M2M terminal according to the service information; and
sending a resource response message to the M2M terminal, wherein the resource response message comprises initial service time and a service duration that are allocated by the AP for the M2M terminal according to the resource request message and the service information such that the M2M terminal sends the service data report message according to the service information, the initial service time, and the service duration.

5. A method for achieving a machine to machine (M2M) service, comprising:
determining a wireless access point (AP) that supports the M2M service when the AP transmits a second service identifier that corresponds to the M2M service supported by the AP to an M2M terminal as a part of a broadcast frame and the second service identifier matches a first service identifier on the M2M terminal that corresponds to the M2M service supported by the M2M terminal;
determining the AP that supports the M2M service when the AP receives a probe request message comprising the first service identifier from the M2M terminal that matches the second service identifier;
establishing a communication connection to the M2M terminal that supports the M2M service;
sending service configuration information to the M2M terminal;
receiving a service data report message that is sent by the M2M terminal according to the service configuration information, wherein the service data report message comprises service data corresponding to the M2M service;
receiving service information from an M2M server that supports the M2M service, wherein the service configuration information sent to the M2M terminal comprises the service information;
receiving an association request message sent by the M2M terminal, wherein the association request message comprises the first service identifier that corresponds to the M2M service supported by the M2M terminal, and registration request indication information;
determining, according to the first service identifier, the M2M server that supports the M2M service; and
sending a registration request message to the M2M server according to the registration request indication information,
wherein the registration request message comprises the M2M terminal identifier,
wherein receiving the service information from the M2M server that supports the M2M service comprises receiving a registration response message sent by the M2M server, and
wherein the registration response message comprises the service information.

6. A method for achieving a machine to machine (M2M) service, comprising:
determining a wireless access point (AP) that supports the M2M service when the AP transmits a second service identifier that corresponds to the M2M service supported by the AP to an M2M terminal as a part of a broadcast frame and the second service identifier matches a first service identifier on the M2M terminal that corresponds to the M2M service supported by the M2M terminal;
determining the AP that supports the M2M service when the AP receives a probe request message comprising the first service identifier from the M2M terminal that aches the second service identifier;
