RanListManager

type RanListManager struct {
	rnibDataService services.RNibDataService
	mux sync.Mutex
	nbIdentityList []*NbIdentity
}

type IRanListManager interface {
	InitNbIdentityList() error
	AddNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
	UpdateNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
	DeleteNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
	GetNbIdentityList() []*entities.NbIdentity
}

InitNbIdentityList

• Triggered on application init, fetches nb identity list from DB and set it on data member.
• rnib error → os.Exit(1)

AddNbIdentity

- saveNodeb calls:
- add_end_request_handler
- e2_setup_request_handler
- every saveNodeb Call will be followed by ranListManager.AddNbIdentity(nodeType, nbIdentity) call

UpdateNbIdentity

DeleteNbIdentity

- removeEnb calls:
- delete_enb_request_handler
- every removeEnb Call will be followed by ranListManager.DeleteNbIdentity(nodeType, nbIdentity) call
- currently, there is no removeGnb call (there's only removeServedNrCells)

GetNbIdentityList

• Returns the in-memory nbIdentity list
• Affected flows: Get Nodeb Ids REST API & Red Button

Get Nodeb States REST API

• Change url from /v1/nodeb/ids to /v1/nodeb/states
• Add ConnectionStatus property to NbIdentity proto (already pushed)
• Get nbIdentity list from memory instead of DB

Red Button REST API

• Similarly, get nbIdentity list from memory instead of DB

RnibWriter Changes

Modify

We shall modify the following methods:

• SaveNodeb(nbIdentity *entities.NbIdentity, nodebInfo *entities.NodebInfo) error
  • Change signature to: SaveNodeb(nbIdentity *entities.NbIdentity, nodebInfo *entities.NodebInfo) error
  • Modify implementation:
    • Remove UNKNOWN nodeType handling (reason: setup is now deterministic)
    • Remove save nbIdentity code - it would be called sequentially externally
      
      
• RemoveEnb(nodebInfo *entities.NodebInfo) error
  • Modify implementation:
    • Delete remove nbIdentity code - it would be called sequentially externally

Add

AddNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
UpdateNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
RemoveNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error

RnibReader Changes

Modify

We shall modify the following methods:

• GetListNodebIds() ([]*entities.NbIdentity, error)
  • Remove UNKNOWN nodeType handling (reason: setup is now deterministic)
