Method and system for negotiating device information, and device thereof

A method for negotiating device information, comprising:

• setting, at a device, a device information network entity for storing device information of devices and a corresponding relation between the device information and identifiers identifying the device information of the devices, the device information being used for a content adaptation during synchronization, the device information network entity being configured to provide stored device information of a given device by using the stored corresponding relation according to a identifier identifying the device information of the given device;
• sending, over a network and by an initiating network entity initiating a data synchronization process, a data synchronization initialization request carrying a first identifier identifying the initiating network entity to a destination network entity of the data synchronization process;
• accessing, by the destination network entity, the device information network entity with the first identifier, and acquiring the device information of the initiating network entity, using the first identifier, from the device information network entity;
• sending, by the destination network entity, a data synchronization initialization response to the initiating network entity;
• wherein the data synchronization initialization response comprises a second identifier identifying the device information of the destination network entity;
• and
• the method further comprises:
• accessing, by the initiating network entity, the device information network entity with the second identifier;
• and
• acquiring the device information of the destination network entity, using the second identifier, from the device information network entity.

A synchronization client for negotiating device information, comprising:

• a data synchronization initialization request sending hardware module, configured to send, over a network, a data synchronization initialization request carrying a first identifier identifying device information of the synchronization client to a synchronization server to initiate a data synchronization process;
• a device information acquiring hardware module, configured to acquire device information, using a second identifier identifying device information of the synchronization server carried in a data synchronization initialization response sent by the synchronization server from a device information server, according to the second identifier carried in the response, and send the acquired device information to a receiving/sending module;
• and
• the receiving/sending hardware module, configured to perform information interaction with the synchronization server based on the acquired device information, wherein the device information is used for a content adaptation during synchronization.

A synchronization server for negotiating device information, comprising:

• a device information acquiring hardware module, configured to
• access a device information server storing device information and acquire device information of a synchronization client, from the device information server, with a first identifier identifying device information of the synchronization client, the first identifier being carried in a data synchronization initialization request sent by the synchronization client to the synchronization server, and
• send the acquired device information to a receiving/sending module;
• the receiving/sending hardware module, configured to perform information interaction with the synchronization client based on the acquired device information;
• a response sending hardware module, configured to send a data synchronization initialization response carrying a second identifier identifying device information of the synchronization server to the synchronization client, wherein the device information is used for a content adaptation during synchronization.
