Method and Device for Dynamically Constructing Virtual Cell

A method for dynamically constructing a virtual cell, applied to an ultra-dense network, comprising:

• User Equipment, UE, selecting a serving cell, using the selected serving cell as a master station and establishing a service on the master station;
• the UE receiving an event A4 from the master station and performing measurement on neighboring cells of the master station;
• when it is judged that there is a cell which satisfies the event A4 in the neighboring cells of the master station, the UE sending an A4 measurement report to the master station;
• and
• the UE receiving a first Radio Resource Control, RRC, connection reconfiguration message from the master station, generating a first encryption key according to the first RRC connection reconfiguration message, performing reestablishment by using the generated first encryption key, sending a first RRC connection reconfiguration completion message to the master station and initiating a random access process to a slave station.

A method for dynamically constructing a virtual cell, applied to an ultra-dense network, comprising:

• a slave station receiving a first adding request message or a second adding request message from a master station, generating a first encryption key according to the first adding request message or the second adding request message, and performing configuration by using the generated first encryption key;
• and
• the slave station sending a first adding command message or a second adding command message to the master station,
• wherein the first adding command message comprises a first encryption algorithm.

A device for dynamically constructing a virtual cell, comprising:

• a first sending module arranged to send an event A4 to User Equipment, UE;
• a first receiving module arranged to receive an A4 measurement report from the UE;
• and
• an adding module arranged to add a cell corresponding to a cell identity carried in the A4 measurement report as a slave station,
• wherein a master station and slave stations form a first virtual cell.

A device for dynamically constructing a virtual cell, comprising:

• a selection module arranged to select a serving cell, use the selected serving cell as a master station and establish a service on the master station;
• a second receiving module arranged to receive an event A4 from the master station and perform measurement on neighboring cells of the master station;
• and receive a first Radio Resource Control, RRC, connection reconfiguration message from the master station, generate a first encryption key according to the first RRC connection reconfiguration message and perform reestablishment by using the generated first encryption key;
• and
• a second sending module arranged to, when it is judged that there is a cell which satisfies the event A4 in the neighboring cells of the master station, send an A4 measurement report to the master station;
• and send a first RRC connection reconfiguration completion message to the master station and initiate a random access process to a slave station.

A device for dynamically constructing a virtual cell, comprising:

• a third receiving module arranged to:
• receive a first adding request message or a second adding request message from a master station, generate a first encryption key according to the first adding request message or the second adding request message and perform configuration by using the generated first encryption key;
• and
• a third sending module arranged to:
• send a first adding command message or a second adding command message to the master station, wherein the first adding command message comprises a first encryption algorithm.
