Problems solved by technology

[0004] However, due to the different paging transmission times of different base stations and the different access delays of UEs of different classes, the UE may access neighboring base stations after the timer expires.
At this time, the neighboring base station will request UE data from the anchor base station, but the anchor base station has deleted the UE context, which makes the UE access process abnormal

Embodiment 1

[0152] After the anchor base station fails to page the UE on the RAN side, it sends a UE unreachable message to the neighbor base station, such as Figure 8 As shown, the paging failure processing method in this embodiment includes:

[0153] The core network sends downlink data to the anchor base station;

[0154] After paging the UE fails, the anchor base station deletes the UE context, notifies the CN, and deletes the UE's core network connection at the same time;

[0155] The anchor base station notifies the adjacent base stations in the UE paging area that the UE is unreachable, and specifically can send a UE unreachable message to the adjacent base stations;

[0156] If the neighboring base station receives the connection request from the UE, the neighboring base station sends a UE connection rejection message to reject the UE's access, or the neighboring base station sends a UE connection establishment message to notify the UE to perform an idle state connection establi...

Embodiment 2

[0158] After receiving the UE data acquisition request from the neighboring base station, the anchor base station notifies the neighboring base station that the UE is unreachable, such as Figure 9 As shown, the paging failure processing method in this embodiment includes:

[0159] The core network sends downlink data to the anchor base station;

[0160] After paging the UE fails, the anchor base station deletes the UE context, notifies the CN, and deletes the UE's core network connection at the same time;

[0161] If the neighboring base station receives the UE's connection request, the neighboring base station requests the anchor base station to obtain UE data, for example, sends a UE data obtaining request message, which carries the UE identifier;

[0162] The anchor base station rejects the request, such as sending a UE connection rejection message, which carries a cause value indicating that the UE is unreachable, or sends a UE unreachable message to a neighboring base s...

Embodiment 3

[0165] The anchor base station carries a timer in the paging message sent to the neighbor base station, such as Figure 10 As shown, the paging failure processing method in this embodiment includes:

[0166] The core network sends downlink data to the anchor base station;

[0167] The anchor base station sends a paging message to the neighboring base stations in the UE paging area, and the paging message carries a timer;

[0168] The neighboring base station sends a paging message and starts the timer;

[0169] If the neighboring base station receives the UE's connection request after the timer expires, the neighboring base station sends a UE connection rejection message to reject the UE's access, or the neighboring base station sends a UE connection establishment message to inform the UE to perform an idle state connection establishment process.

Abstract

The invention provides a paging failure processing method and a base station, and belongs to the technical field of wireless communication. The paging failure processing method applied to the base station comprises the following steps: after the paging of user equipment fails or when a request message sent by an adjacent base station and used for requesting to obtain information of the user equipment, the adjacent base station is informed that the user equipment is unreachable. The paging failure processing method applied to the adjacent base station in a user equipment paging area comprises the steps of receiving user equipment unreachable information sent by the base station, and refusing a deactivation-state or light-connection-state connection request of the user equipment. According to the technical scheme, the base station can inform the adjacent base station after the paging of the user equipment (UE) fails on a wireless side, so that the access process of the UE is guaranteed not to be abnormal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a paging failure processing method and a base station. Background technique [0002] 5G (fifth generation mobile communication technology) introduces a new deactivation state. When the UE (user terminal) is in the deactivation state, there is no RRC (radio resource control) connection between the UE and the base station, but the anchor base station is still The UE context is reserved and the core network connection of the UE is maintained. The behavior of the RAN (Radio Access Network) side of the UE is similar to the idle state, while the core network is still in the connected state. At this time, if figure 1 As shown, if downlink data arrives, the core network will not trigger the paging process, but will continue to send data to the anchor base station, and the anchor base station will trigger the paging process to search for the UE in the paging area on the RA...
