Description

Method and device for indicating paging message, electronic device

Technical field

The present disclosure relates to the field of wireless communication systems, for example, to a method and apparatus for indicating a paging message, and an electronic device.

Background technique

As the user equipment (UE) and services grow, the signaling load between the UE and the network is large. In order to reduce the air interface signaling overhead and delay between the user and the base station, based on long-term evolution (Long Term Evolution) The LTE system proposes a new mode, which can be called a light connection mode. In the light connection mode, in order to hide the mobility and state transition of the UE that has no data transmission for a long time in the core network, the connection of the S1 port is maintained and activated, and these UEs can be associated with an evolved Node B (eNB). Stay connected. For UEs in light-connect mode, eNB-based paging is feasible and advantageous in reducing signaling load and latency.

In the LTE system, the network may send a paging message to the UE in the idle state and the connected state, and the paging process may be triggered by the Mobility Management Entity (MME) to notify a certain UE to receive the paging request, or The eNB triggers to notify the UE to receive system information update, information of various early warning systems, and the like. Early warning systems include Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert Service (CMAS).

When the eNB and the UE are in the light connection mode, the S1 port is also in a connected state. In the case that the MME is in an idle state, if the eNB is still in the light connection mode, the eNB sends the paging message to the UE when the MME sends a paging message to the eNB. After receiving the paging message, the UE in the light connection mode does not know that the MME is in an idle state, and does not distinguish whether the paging is from the MME or the eNB, and therefore considers the paging message as a paging from the eNB. The UE initiates a Radio Resource Control (RRC) resume procedure to enter an RRC connected state.

detailed description

The embodiment of the invention provides a method for indicating a paging message, so that the UE can distinguish whether the paging message is from the core network element or from the eNB. In the embodiment of the present invention, the core network element is an MME.

In the first case, when the MME pages a certain UE, a paging message is sent to the eNB. After receiving the paging message from the MME, the eNB adds an indication bit to the paging message to indicate that the paging message is from the MME. The eNB sends a paging message with the indicated bit to the UE through the air interface. After receiving the paging message, the UE may determine that the paging message is initiated by the MME according to the paging message indication bit, and perform an operation corresponding to the paging message initiated by the MME.

In the second case, when the eNB initiates paging in the light connection mode to the UE connected in the light connection mode with the eNB, an indication bit is added in the paging message to indicate that the paging message is from the eNB. The eNB sends a paging message with the indicated bit to the UE through the air interface. After receiving the paging message, the UE may determine that the paging message is initiated by the eNB according to the paging message indication bit, and the UE may perform subsequent corresponding operations.

eNB side processing:

In the first case, after receiving the paging message initiated by the MME, the eNB adds an indication bit to the paging message to indicate that the paging message is from the MME, so that the UE that receives the paging message can indicate the bit according to the paging message. It is determined that the paging message it receives is sent by the MME. If the MME sends the paging message to the eNB in the idle state, if the eNB receives the paging message sent by the MME, it can determine that the connection with the MME has been released, and the eNB and the UE are still in the light connection mode. . In order to keep the state consistent with the MME, the eNB needs to release the UE context, so that the eNB enters the RRC idle state.

In the second case, an indication bit is added to the paging message to indicate that the paging message is from the eNB, so that the UE receiving the paging message can determine that the received paging message is sent by the eNB according to the paging message indication bit. .

UE side processing:

In the first case, after receiving the paging message from the eNB, the bit is indicated according to the paging message. It is determined that the paging message is from the MME. Since the MME sends a paging message to the UE through the eNB in the idle state, the UE may determine that the MME has an abnormality and enter an idle state. In order to maintain the state consistent with the MME, the UE releases the UE context and enters the RRC idle state.

In the second case, after receiving the paging message from the eNB, it is determined that the paging message is from the eNB according to the paging message indication bit, and the UE can perform subsequent corresponding operations.
