Embodiment 1

[0147] Not all 5G base stations or all cells corresponding to (or including) a 5G base station, or all 4.5G base stations (eLTE eNB) or all cells corresponding to (or including) a 4.5G base station support Inactive state, so the base stations (and / or cells) need to interact with each other whether to support the Inactive state. The interaction can be during the interface establishment process, such as Xn interface establishment (that is, the establishment of an interface between two 5G base stations), the establishment of an X2 interface (that is, the establishment of an interface between two 4.5G base stations), the establishment of an Xx interface (that is, the establishment of an interface between a 5G base station and a 4.5 G base stations) can also interact during the base station update process, for example, 5G base station (gNB) configuration update. The following takes the establishment of the Xn interface as an example to introduce how base stations (and / or cells) int...

Embodiment 2

[0158] Base stations need to exchange RPA information, so that RNA can be more accurately allocated to terminals when needed. Similar to whether the interaction supports the Inactive state, the exchanged RPA information can be exchanged during the interface establishment process between base stations or during the base station update process. For details, refer to the above description of whether the interaction supports the Inactive state, and will not be repeated here. The following takes the establishment of the Xn interface as an example to introduce how to exchange RPA information between base stations. It can be understood that how to exchange cell identities between base stations is similar to how to exchange RPA information, and will not be repeated here.

Embodiment 3

[0178] Image 6 is a schematic diagram of an RNA update process provided by this application, such as Image 6 Shown:

[0179] S1301: The terminal sends an RRC connection resume request (RRC connection resume request) to the new (new) gNB, and the request includes terminal identification information (such as Resume ID information) and terminal recently accessed RNA information. This RNA information can enable the new gNB to more accurately assign RNA to terminals. Optionally, the RRC connection recovery request also carries the residence time of the terminal, and the residence time is the residence time of at least one cell or at least one network device indicated by the RNA information recently visited by the terminal.

[0180] Optionally, S1302: The new gNB judges whether it supports the Inactive state or whether the cell where the terminal is currently located supports the Inactive state, or whether the PLMN corresponding to the cell where the terminal is currently locate...

Abstract

The present application provides a method for allocating RNA, network equipment, and terminals, so that when RNA needs to be reassigned to terminals in the Inactive state (or connected state), according to the recently accessed RNA information of the terminal (also can be understood as terminal mobile trajectory) and / or whether to support the inactive state, allocate RNA to the terminal device to make the allocation of RNA more reasonable, reduce aperiodic RNA update, and save signaling overhead and power consumption. At the same time, this application can further enrich the mobile trajectory of the terminal by carrying this message according to the residence time of the terminal, so as to give the network side a more accurate judgment, so that the network side can allocate new RNA more accurately.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method for distributing RNA, network equipment and terminals. Background technique [0002] The radio resource control (Radio Resource Control, RRC) deactivated state, also known as the Inactive state, is a newly defined terminal communication state in 5G. In the Inactive state, the core network, network devices, and terminals all retain corresponding context information, but the terminal moves within the notification area (RAN based Notification Area, RNA) of the Radio Access Network (RAN) in the Inactive state , the network may not be notified, but the network needs to be notified after the RNA allocated by the network side for the terminal in the inactive state is removed. When a terminal moves from an old network device to a new network device, in some cases, the new network device may reassign RNA to the terminal. These situations may include that th...
