Communication control method and device

Abstract

The embodiment of the invention provides a communication control method and a device. The method comprises the following steps: after receiving a first request message sent by target user equipment, a target base station interacts with a source base station to obtain context information of the target user equipment; under the condition that the first frequency band does not conform to the frequency band filtering principle of the target base station, interacting with the target user equipment, so that the target user equipment is switched to an activated state; and interacting with the target user equipment in the activated state to obtain second capability information, the second capability information being capability information of the target user equipment on a second frequency band, and the second frequency band being a frequency band conforming to the frequency band filtering principle of the target base station. Therefore, according to the scheme of the invention, the problem in the prior art that the service recovery time delay is relatively long because the resident base station needs to acquire the UE capability of the frequency band concerned by the base station from the UE side when the UE recovers the service after the RNA is updated is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a communication control method and device. Background technique [0002] The 5G StandAlone (SA) system introduces the user's inactive state and its behavior, which involves the Radio Access Network Notification Area (RNA). Wherein, RNA is a subset of the registration area of ​​the core network, and may include one or more cells. When an inactive user moves into a new RNA, it needs to trigger an RNA update process (finally return to the Inactive state) to determine the user's context anchor cell in the new RNA. Subsequently, if there is signaling or data from the core network, the radio access network (RNA) paging within the new RNA range will be triggered through the context anchor cell, and the inactive user will be called up and restored to the active state to continue processing. [0003] In addition, the user equipment (UE) capability reporting mechanis...

Problems solved by technology

[0006] Embodiments of the present invention provide a communication control method and device to solve the problem that in the prior art, after the RNA is updated, when the UE resumes services, the base station that resides this time needs to obtain the UE capabilities of the frequency band it cares about from the UE side. As a result, the problem of long service recovery delay
