Description

Paging processing method and device

Technical Field

The embodiment of the invention relates to the technical field of wireless communication, in particular to a paging processing method and equipment.

Background

In the 5G system, system paging introduces a new Network-initiated page (i.e., Radio Access Network (RAN) page) in addition to a core Network-initiated page (i.e., CN page). Besides, the UE states in the 5G system include an inactive state, which has similarities with a sub-state of the connected state (i.e., a light connected state), in addition to an idle state and a connected state, and the UE in the inactive state can perform corresponding processing on the received system page.

After receiving RAN paging, the light connection state UE completes an RRC connection recovery process through signaling interaction with a base station; after receiving the CN paging, the light connection state UE locally enters an idle state and does not perform signaling interaction with the base station; and after receiving the CN paging, the idle-state UE completes the RRC connection establishment process by carrying out signaling interaction with the base station.

However, when the UE and the base station understand the current UE state to be inconsistent, for example, the UE considers that the UE is in a light connection state, and the base station releases the access network context of the UE and does not establish a connection with the core network, the base station considers that the UE is in an idle state, and sends a CN page to the UE. At this time, if the UE is performing a Radio Resource Control (RRC) connection recovery procedure, the UE may not know how to handle the CN page.

s401, the network equipment sends RAN paging information to the UE.

S402, the UE receives RAN paging information sent by the network equipment and sends a random access leader sequence to the network equipment.

The random access preamble sequence is used for instructing the network device to complete the timing design of the uplink.

S403, the network equipment receives the random access leader sequence sent by the UE and sends a random access response to the UE.

The random access response is used for indicating the UE to acquire a time advance command sent by the network equipment and indicating the UE to send time-frequency resources of an RRC connection recovery request.

S404, the UE receives the random access response sent by the network equipment and sends an RRC connection recovery request to the network equipment.

Wherein, the UE may receive a CN paging message sent by the network device through the communication interface 12.

Exemplarily, as shown in fig. 4, a schematic network architecture diagram of a UE according to an embodiment of the present invention is provided. The network architecture may include: a physical layer, a Media Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, an RRC layer, and a Non-Access Stratum (NAS) layer.

The physical layer is at the bottom layer of the network architecture, and can provide a transmission medium and interconnection equipment for data communication between the equipment, and provide a reliable environment for data transmission. The MAC layer is mainly responsible for controlling and interfacing with the physical medium of the physical layer. The RLC layer provides segmentation and retransmission services for user and control data. The PDCP layer may process RRC messages on the control plane and internet protocol packets on the user plane. The RRC layer is responsible for broadcasting system information and transmitting dedicated control information. The NAS layer is a non-access layer, is an upper layer in a network architecture, and is responsible for related functions and procedures independent of a radio access technology.

Illustratively, after receiving the CN paging message, the physical layer of the UE transmits the CN paging message to the MAC layer or the RRC layer of the UE, so that the MAC layer or the RRC layer performs corresponding operation processing according to a relevant protocol of the RRC layer.

S303, the UE performs target operation according to the receiving time of the CN paging message.

For example, in a first application scenario of the embodiment of the present invention, when the timing of receiving the CN paging message is a first timing, the target operation is: and continuing to execute the RRC connection recovery process or stopping executing the RRC connection recovery process, and executing the RRC connection establishment process. The first opportunity is after the random access preamble sequence is sent in the RRC connection recovery process and before the random access response is received.

The RRC connection request includes an RRC connection recovery back-off indication, where the RRC connection recovery back-off indication is used to instruct the UE to perform an RRC connection establishment procedure.

For example, the RRC connection recovery fallback indication in the embodiment of the present invention may be 1 bit of an establishment cause field extension in the RRC connection request, where the 1 bit is used to indicate that the UE backs to the RRC connection establishment procedure.

S303c1, the UE performs: and receiving an RRC connection establishment response sent by the network equipment, and sending an RRC connection establishment success message to the network equipment.

The second opportunity is after receiving the random access response in the RRC connection recovery process and before sending the RRC connection recovery request.

It can be understood that, in the second application scenario of the embodiment of the present invention, the "UE receives the CN paging message sent by the network device" is between S403 and S404.

For example, in a third application scenario of the embodiment of the present invention, when the CN paging message reception timing is a third timing, the target operation is: and stopping executing the RRC connection recovery process, and switching the UE from the inactive state to the idle state. The third opportunity is after the RRC connection recovery request is sent in the RRC connection recovery process and before the RRC connection recovery response, the RRC connection establishment response, or the RRC connection rejection response is received.

It can be understood that, in the third application scenario of the embodiment of the present invention, the "UE receives the CN paging message sent by the network device" is between S404 and S405.

Optionally, in a third application scenario of the embodiment of the present invention, with reference to fig. 3, as shown in fig. 11, the step S303 may be specifically implemented by the steps S303e (or S303f) and S303 g:

s303e, the UE performs: and stopping receiving the RRC connection recovery response or the RRC connection establishment response sent by the network equipment, and stopping sending the RRC connection recovery success message or the RRC connection establishment success message to the network equipment.

S303f, the UE performs: and stopping receiving the RRC connection rejection response sent by the network equipment.

S303g, the UE performs: and sending an RRC connection release message to the NAS layer, releasing the access network context and the network configuration parameters of the UE according to the indication of the NAS layer, and switching the UE from the inactive state to the idle state.

Illustratively, the UE sends an RRC connection release message to the NAS layer, and the RRC connection release message includes a reason indicating connection release, such as failure of an RRC connection recovery procedure. In the embodiment of the invention, the indication of the NAS layer can be triggered locally by the UE to realize the RRC connection local release of the UE; and the RRC layer of the UE actively releases the RRC connection according to the indication of the NAS layer and actively enters an idle state without informing the network equipment.

The embodiment of the invention provides a paging processing method, which defines the behavior of UE, so that the UE can perform corresponding operation according to the receiving time of CN paging messages in the process of executing RRC connection recovery, and the problem that the UE cannot correctly process CN paging is solved, thereby ensuring the correctness of the behavior of the UE.
