Method for state transition and network device


A method for a state transition includes determining whether a user equipment (UE) is a UE frequently performing state transitions. When the state of the UE is required to be transitioned to the idle state, a state of the UE is transitioned to a paging channel (PCH) state if the UE is a UE frequently performing state transitions. If the UE is a UE infrequently performing state transitions, the state of the UE is transitioned to the idle state.

This application is a continuation of co-pending International Application Ser. No. PCT/CN2011/072004, filed Mar. 21, 2011, which claims priority to Chinese Patent Application No. 201010129163.1, filed Mar. 22, 2010, both of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of communications, and in particular, to a method for a state transition and a network device.

BACKGROUND

In order to achieve the aims of intelligence, electricity saving and communication resource saving, currently, some User Equipments (UEs) may automatically perform a state transition between a connected state and an idle state as required.

For example, when an intelligent mobile phone is in an idle state, if service data to be sent exists, the intelligent mobile phone automatically sends a Radio Resource Control (RRC) signaling connection request to an access network side device (such as a base station controller), so that the access network side device sets up a radio access bearer for the intelligent mobile phone according to the RRC signaling connection request and transits the intelligent mobile phone from the idle state to a connected state; when the intelligent mobile phone is in the connected state, if no service data to be sent exists, the intelligent mobile phone automatically sends a Signaling Connection Release Indication to the access network side device, so that the access network side device releases the radio access bearer set up for the intelligent mobile phone according to the Signaling Connection Release Indication and transits the intelligent mobile phone from the connected state to the idle state.

However, when the state of the UE is frequently transitioned, the access network side device has to frequently set up/release the radio access bearer for the UE, resulting in a heavy workload.

SUMMARY

OF THE INVENTION

Embodiments of the present disclosure provide a method for a state transition and a network device, which are capable of lightening the workload of an access network side device during a state transition process of a UE.

In one aspect, an embodiment of the present disclosure provides a method for a state transition, which includes: judging whether a UE is a UE frequently performing state transitions; transitioning a state of the UE to a Paging Channel (PCH) state if the UE is a UE frequently performing state transitions and when the state of the UE is required to be transitioned to an idle state; and transitioning the state of the UE to the idle state if the UE is a UE infrequently performing state transitions and when the state of the UE is required to be transitioned to the idle state.

In another aspect, an embodiment of the present disclosure further provides a network device, including 1 a judging module, configured to judge whether a UE is a UE frequently performing state transitions and a state transition module, configured to transit a state of the UE to a PCH state if the judging module judges that the UE is a UE frequently performing state transitions and when the state of the UE is required to be transitioned to an idle state, and transit the state of the UE to the idle state if the judging module judges that the UE is a UE infrequently performing state transitions and when the state of the UE is required to be transitioned to the idle state.

For the method for a state transition and the network device provided in the embodiments of the present disclosure, the UE frequently performing state transitions is transitioned to the PCH state when the state of the UE is required to be transitioned to the idle state, so that an access network side device does not need to frequently set up/release a radio access bearer for the UE, thereby lightening the workload of the access network side device during a state transition process of the UE frequently performing state transitions; and the UE infrequently performing state transitions is transitioned to the idle state when the state of the UE is required to be transitioned to the idle state, so that the access network side device does not need to maintain the PCH state of the UE infrequently performing state transitions, thereby lightening the workload of the access network side device during a state transition process of the UE infrequently performing state transitions.
