Description

Processing method, network equipment, device and storage medium for NG link broken link

Technical Field

The present application relates to the field of communications technologies, and in particular, to a processing method, a network device, an apparatus, and a storage medium for NG link dropping.

Background

In SA & NSA (standard & Not standard), when an endec (LTE-NR Dual connectivity) link is broken, the cell is switched from the SA & NSA state to the SA (standard) state, and when an NG (link between NG-RAN and 5G core network 5 GC) link is broken, the cell is switched from the SA & NSA state to the NSA state.

When the cell is switched from the SA & NSA state to the NSA state, the RRC (radio resource control) procedure involved is as follows: informing a MIB (master information block) message of a physical layer to set to a cell barring status, informing a MAC (media access control) to broadcast a SIB (system information block) not to be sent, informing a Radio Resource Management (RRM) to change a cell status to a cell barring status, and not initiating access after a terminal searches for a cell. For SA users: considering that NG link flash is more and consistent with SCTP (stream control transmission protocol) link, users are not deleted and wait for survival detection and then release users.

The existing two cell judgment logics of OM (Operation Maintenance) during NG link chain breaking are as follows: 1) When the NG link and the SCTP link are all failed, the NR (New Radio) side deactivates the SA cell and the composite cell; 2) Reporting the fault of the last NG link, and if the original state of the cell is the 'supporting SA/NSA state', the state needs to be transferred to the 'supporting NSA state'; if the original state is the 'SA supporting state', the ENDC link is completely disconnected, and the NR side also deactivates the SA cell.

The processing logic in the NG link chain breaking process has the following problems: after the NG link is broken, the SA user in the cell cannot perform the service, but since the OM does not delete the cell, the SA user still resides in the cell, so that the SA user cannot perform the service for a long time in the cell, and the user perception is very poor.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

First, terms referred to in the embodiments of the present application will be described.

Deployment of a 5G (the 5th Generation, fifth Generation communication technology) network may include two parts: NG-RAN (Next Generation Radio Access Network) and 5GC (the 5th Generation Core Network). The wireless access network mainly comprises a base station and provides a wireless access function for users. The core network mainly provides internet access service and corresponding management function for users. Since the investment for deploying a new network is huge and the two parts are to be deployed separately, the 3GPP (3 rd generation partnership project) is divided into two ways to deploy: SA (stand alone) and NSA (non-stand alone). The SA mode is to newly build an existing network including a new base station, a backhaul link, and a core network, and the NSA mode is to use the existing 4G (the 4th Generation, fourth Generation communication technology) infrastructure to deploy a 5G network. In the initial stage of 5G networking, the NSA can utilize the resources of the existing 4G network to the maximum extent, and the purpose of rapidly deploying 5G is achieved.

There are also a plurality of different types of NSA modes, such as an endec (LTE-NR Dual Connectivity) type, an NGEN-DC (Next Generation EN-DC) type, an NE-DC (NR EUTRA-Dual Connectivity) type, and an NR-DC (NR Dual Connectivity) type. Currently, the development of the ENDC form is the main direction. The present application is also described taking the endec mode as an example, but the present application is not limited to the endec mode and can be applied to other modes.

At present, when NSA & SA (independent & non-independent composite networking) co-cell configuration is carried out, when an NG link of an SA cell is broken, in order to ensure that an SA user cannot repeatedly initiate access in the broken link cell and ensure that the user of an adjacent cell cannot initiate switching to the cell due to signal intensity change, the cell can be deactivated, the SA user in the cell cannot carry out service, and because OM does not delete the cell, the SA user still resides in the cell, so that the SA user cannot carry out service in the cell for a long time, and user perception is extremely poor.

In order to solve the above problem, embodiments of the present application provide a processing method, a network device, an apparatus, and a storage medium when an NG link is broken. It should be noted that the technical solution provided in the embodiments of the present application can be applied to various systems, especially 5G systems. For example, the applicable system may be a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a long term evolution (long term evolution, LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an LTE-a (long term evolution) system, a universal mobile system (universal mobile telecommunications system, UMTS), a universal internet Access (WiMAX) system, a New Radio Network (NR) system, etc. These various systems include terminal devices and network devices. The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5 GS), and the like.

Fig. 1 is a schematic flowchart of a processing method for NG link dropping according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 100, under the condition that the networking mode of the current cell is an independent and non-independent composite networking SA & NSA mode, if the NG link of the link between the 5G wireless access network and the 5G core network is interrupted, inquiring whether other available NG links exist;

specifically, the execution subject of the embodiment of the present application is a network device.

The network device according to the embodiment of the present application may be a base station, and the base station may include a plurality of cells for providing services to a terminal. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to exchange received air frames and Internet Protocol (IP) packets with one another as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communications network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), a network device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB) or an e-NodeB) in a Long Term Evolution (LTE) System, a 5G Base Station (gNB) in a 5G network architecture (next generation System), a Home evolved Node B (HeNB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico), and the like, which are not limited in the embodiments of the present application. In some network architectures, a network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

For convenience of description, the method provided by the embodiment of the present application is described below by taking a base station as an example. As communication technology evolves, the name "base station" may change. It is worth pointing out that the embodiments of the present application only use 4G networks and 5G networks as examples, but should not be taken as a scenario limitation of the embodiments of the present invention.

Under the condition that the networking mode of the current cell is an independent and non-independent combined networking SA & NSA mode, if the base station corresponding to the current cell learns that the NG link of the link between the base station and the 5G core network is interrupted, whether other available NG links exist is inquired to judge whether the interrupted NG link is the last NG link between the base station corresponding to the current cell and the core network.

Step 101, if there are no other available NG links, setting the networking mode of the current cell to a non-independent networking NSA mode;

specifically, if the base station learns that there are no other available NG links, it is determined that the NG link with the interruption is the last NG link with the core network, and at this time, the networking mode of the current cell is set to the dependent networking NSA mode.

When the networking mode of the current cell is set to the non-independent networking NSA mode, the related RRC flows are as follows: the method comprises the steps of setting a master information block MIB message of a physical layer to be informed to be in a cell forbidden CELLBAR state, informing a Media Access Control (MAC) layer to broadcast a System Information Block (SIB) message and informing a Radio Resource Management (RRM) layer of changing the cell state to the CELLBAR state, so that the UE cannot initiate access after searching the cell.

It should be noted that, if the base station acquires that there are other available NG links, the process is terminated.

Step 102, judging whether an Xn link exists, if so, notifying an adjacent base station that the current cell is unavailable through the Xn link, and deleting the adjacent cell relation;

specifically, the base station and the neighboring base station communicate with each other through an Xn interface, and a communication link between the base station and the neighboring base station is an Xn link.

The base station judges whether an Xn link exists, if the Xn link exists, the adjacent base station is informed that the current cell is unavailable through the Xn link, and the adjacent cell relation is deleted, so that the user of the adjacent cell cannot be switched to the current cell.

Step 103, redirecting the users of the independent networking SA of the current cell to a completely same coverage cell or a partially same coverage cell.

Specifically, the cell completely covered refers to a cell which shares a station address with the current cell and has the same coverage area; the partial same-coverage cell refers to a cell which shares a station with the current cell and has the same coverage area.

The SA user refers to a user terminal residing in an SA cell of the independent networking mode. Under the condition that the networking mode of the current cell is an independent and non-independent composite networking SA & NSA mode, SA users and NSA users exist in the current cell.

The base station redirects the independent networking SA users of the current cell to a completely same-coverage cell or a partially same-coverage cell, namely, the base station transfers the SA users to the completely same-coverage cell or the partially same-coverage cell, so that the SA users can normally perform service processing.

It should be noted that, if there is no SA user in the current cell, step 103 does not need to be executed.

According to the processing method for NG link chain breakage provided by the embodiment of the application, under the mode that the cell is configured to be in the SA & NSA mode, in order to ensure that the NSA user perception is not influenced and the cell is not deleted when the NG link chain breakage, the adjacent cell deleting relation is notified through the Xn link, the SA user is redirected to the completely same coverage cell or the partially same coverage cell, the SA user can normally perform service processing, and the user perception of the SA user in the cell when the NG link chain breakage is improved.

In an embodiment, the redirecting the independent networking SA user of the current cell to the fully or partially co-covering neighboring cell includes:

Specifically, the base station redirects the independent networking SA user of the current cell to a completely same-coverage neighboring cell or a partially same-coverage neighboring cell by sending an RRC release message to the SA user.

And the RRC release message carries a target frequency point, wherein the target frequency point is a frequency point which is completely same as a coverage cell or a frequency point which is partially same as the coverage cell.

It should be noted that, the base station acquires a frequency point of the current cell, which is completely or partially identical to the frequency point of the coverage cell, as a target frequency point, and sends the target frequency point to the SA user through an RRC release message, so that the SA user can redirect to a completely or partially identical coverage neighboring cell according to the target frequency point.

According to the processing method for NG link chain breakage provided by the embodiment of the application, the independent networking SA user of the current cell is redirected to the completely same-coverage adjacent cell or the partially same-coverage adjacent cell by adopting the RRC release message, so that the purpose of improving the perception of the SA user in the cell is achieved, and the implementation mode is simple.

In another embodiment of the present invention, on the basis of the above embodiment, after the determining whether the Xn link exists, the method further includes:

Specifically, if the base station determines that the Xn link does not exist, the SA user of the current cell is directly redirected to a completely same coverage cell or a partially same coverage cell.

The independent networking SA user of the current cell can be redirected to a completely same-coverage neighboring cell or a partially same-coverage neighboring cell by sending an RRC release message to the SA user, wherein the RRC release message carries a target frequency point, and the target frequency point is a frequency point of the completely same-coverage cell or a frequency point of the partially same-coverage cell.

According to the processing method for NG link chain breakage provided by the embodiment of the application, under the condition that an Xn link does not exist, the base station directly redirects the SA users of the current cell to the completely same-coverage cell or the partially same-coverage cell, and the perception of the SA users in the cell can also be improved.

Specifically, under the condition that the networking mode of the current cell is the independent networking SA mode, if the NG link is known to be interrupted, whether other available NG links exist is queried to determine whether the NG link interrupted is the last NG link between the base station corresponding to the current cell and the core network.

And if the base station knows that no other NG link is available, determining the broken NG link as the last NG link between the broken NG link and the core network, and redirecting the independent networking SA user of the current cell to a completely same coverage cell or a partially same coverage cell.

The base station can redirect the independent networking SA user of the current cell to a completely same-coverage neighboring cell or a partially same-coverage neighboring cell by sending an RRC release message to the SA user. And the RRC release message carries a target frequency point, wherein the target frequency point is a frequency point which is completely same as a coverage cell or a frequency point which is partially same as the coverage cell.

According to the processing method for NG link chain breakage provided by the embodiment of the application, in the SA mode of the cell, in order to guarantee that the SA user can continue service processing when the NG link chain breakage occurs, the SA user is redirected to the cell which completely covers the same cell or a cell which partially covers the same cell, and user perception of the SA user in the cell when the NG link chain breakage occurs is improved.
