Method, device and electronic device for indicating paging message

Technical field

[0001] The present invention relates to the field of wireless communication system technologies, and in particular, to a method and an apparatus for indicating a paging message, and an electronic device in a future wireless communication system.

Background technique

[0002] With the growth of user equipment (UE, Equipment) and services, the signaling load between the UE and the network is very large. In order to reduce air interface signaling overhead and delay between the user and the base station, based on the current long-term The Long Term Evolution (LTE) system proposes a new mode that allows some UEs that have no data transmission for a long time to stay in this mode. In this mode, in order to hide the mobility of the UE and the state transition from the core network, the connection of the S1 interface is maintained and activated, and the UE and the evolved Node B (eNB) are in this mode. Conveniently, this mode is called light connection mode. For the UE in the light connection mode, eNB-initiated paging is feasible and advantageous in reducing signaling load and delay.

[0003] In the current LTE system, a network may send a paging message to idle and connected UEs. The paging process may be triggered by a mobility management entity (10)ffi, Mobility Management Entity) to notify a certain UE to receive a paging. The request, or triggered by the eNB, is used to notify the system information update, or to notify the UE to receive information such as earthquake and tsunami warning system (ETWS, Earthquake and Tsunami Warning System) and commercial mobile alerting system (CMAS, Commercial Mobile Alert Service).

[0004] For the new mode light connection, when the eNB and the UE are in the light connection mode, the SI port is in a connected state. If the MME fails to enter the idle state and the eNB does not detect it, the eNB and the UE are still in the light connection mode. When a paging message from the MME is sent to the eNB and the eNB sends the message to the UE, the UE in light connectivity receives a paging message and thinks that it is paging from the eNB and initiates radio resource management (RRC, Radio Resource). The recovery process enters the RRC connection state. At this time, the MME is in the idle state. Therefore, the eNB and the UE E do not match. Therefore, the UE needs to distinguish whether the paging is from the MME or the eNB. Based on this, how the UE distinguishes whether the paging is from the MME or the eNB is a problem to be solved.

detailed description

For a more detailed understanding of the features and technical content of the embodiments of the present invention, the following describes the implementation of the embodiments of the present invention in detail with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the present invention. Examples. [0030] The embodiment of the present invention provides a method for indicating a paging message, which can distinguish whether paging is from a core network. A blank is from an eNB. Taking the core network element as the MME as an example, in the first case, when the MME pages a certain UE, it sends a paging message to the eNB. The NB increases the paging message after receiving the paging message from the MME. The indication bit indicates that the paging message is from the MME. The NB adds the paging message with the indication bit to the UEJE through the air interface. After receiving the paging message, the paging message can be determined by the MME according to the indication bit in the paging message. Initiate and perform the corresponding operation initiated by the MME. In the second case, when the eNB initiates paging in light connection mode, an indication bit is added in the paging message to indicate that the paging message is from the eNB. The NB sends a paging message added with the indication bit to the UE through the air interface. . ! After receiving the paging message, according to the indication bit in the paging message, it can be determined that the paging message is initiated by the eNB, which is regarded as a normal process, and the UE can initiate subsequent normal processes.

[0031] eNB side processing: In the first case, after receiving the paging initiated by the MME, the paging message is filled in. Specifically, the paging message is indicated in the paging message to indicate that the paging is from UE E so that the UE can determine . Since the leg E will send a page to the eNB in ​​the idle state, the eNB may determine that the connection with the MME has been released, and the eNB side is still in the light connection mode. To maintain consistency with the state of the MME, the eNB needs to release the UE context and put the eNB into the RRC idle state. In the second case, paging is indicated in the paging message by the indication bit from the eNB for the UE to judge.

[0032] UE-side processing: In the first case, after receiving the paging from the eNB, the paging from the MME is determined according to the indication bits in the paging message. Since the MME sends a page to the UE in the idle state, the UE can determine that the MME has abnormality and enter the idle state. In order to maintain the same state as the MME, the UE releases the UE context and enters the RRC idle state. In the second case, after receiving the paging from the eNB, the paging from the eNB is determined according to the indication bit in the paging message, which is regarded as a normal flow, and the UE can initiate subsequent normal processes.

[0058] Here, the message IE of the paging message indication bit is defined as shown by a dashed frame in FIG.

[0059] 3) After the eNB completes the filling of the paging message, the eNB sends the paging message to the UE through the air interface.

[0060] 4) After the eNB sends the paging message to the UE, the eNB releases the context information of the held UE to enter the RRC idle state in order to keep the same with the state of the MME.

[0061] 5) After the UE receives the paging message of the eNB, the UE parses the paging message to see that the paging indicator bit is False, and then considers that the paging is from the MME.

[0062] 6) The UE considers the paging from the MME according to the parsed paging message indication bit. To maintain consistency with the MME status, the UE releases the UE context and enters the RRC idle state.
