RF capabilities information.
Base station includes attach request Attach Request according to RRC Connect Complete signalings and selects network section
Point MME (Mobility Management Entity), then send initial mobile communication terminal message to network node MME
Initial UE massage include non-access NAS layers of Attach request message.Network node MME is sent just to base station
Beginning context sets request message Initial Context Setup Request, and default bearing is established in request, wherein, initially
Context sets request message Initial Context Setup Request to include NAS layers of attachment and receives request Attach
Accept, activation default EPS bearing context request message Activate default EPS bearer context
request。
Base station receives initial context and sets request message Initial Context Setup Request, if do not wrapped
Information containing RF capabilities, then base station send RF capabilities information to mobile communication terminal and send RF capabilities inquiry request, inquiry
Mobile communication terminal carrier aggregation capacity.Then mobile communication terminal sends RF capabilities according to RF capabilities inquiry request to base station
Information reports mobile communication terminal carrier polymerization capability information.
In the present embodiment, base station sends the network node MME that initial mobile communication terminal message accesses network to LTE,
Middle network node MME has the function of access control, mobile management and attachment and attachment removal etc., and network node MME is fed back to
Base station requests establish default bearing, and base station can judge whether according to the network node MME results fed back comprising mobile communication end
The RF capabilities information at end so ensures that mobile communication terminal can be by the carrier aggregation capacity signals base of itself, and base station is known
Successfully the mobile communication terminal of CA (i.e. 4G+) could be supported subsequently to use LTE- after the carrier aggregation capacity of mobile communication terminal
A networks are had laid a good foundation.
