Referring to FIG. 1, the mobile communication terminal 102 supporting CA carrier aggregation establishes a connection with the base station 104 through LTE random access, and then increases the LTE network speed through the CA carrier aggregation process. The base station refers to a public mobile communication base station, and in a certain radio coverage area, information can be transmitted between the mobile communication switching center and the mobile telephone terminal. Long Term Evolution-Advanced (LTE-A) is a Universal Mobile Telecommunications System (UMTS) technology standard customized by the 3rd Generation Partnership Project (3GPP). The evolutionary standard for the next phase of Long Term Evolution.

The CA is a technology for increasing the transmission bandwidth in the LTE-A system. It can aggregate 2 to 5 LTE carrier component (Componet Carriers, CCs) to achieve a transmission bandwidth of up to 100 MHz, which is effective by increasing the bandwidth resources of the physical layer.

In the LTE-A system, the user equipment (UE) needs to perform downlink synchronization before communicating with the Evolved Node B (eNodeB) in the LTE. On this basis, the uplink synchronization is completed, and then the LTE is accessed through the carrier aggregation process. -A network speed.

In an embodiment, as shown in FIG. 2, a method for controlling radio frequency capability reporting in carrier aggregation is provided. The method is applied to the mobile communication terminal shown in FIG.

Step 210: Start a search network sweep and obtain an array of scanned frequency bands.

The mobile communication terminal supporting CA (ie, 4G+) is powered on or plugged in or re-switched, and the modem modem starts the search process. Specifically, the mobile communication terminal first needs physical downlink synchronization, search and measurement for cell selection, and selects a suitable one. After the acceptable cell, the camping process begins and begins to attach. Generally, one base station will cover multiple cells, so the mobile communication terminal finds a suitable cell, that is, obtains a base station corresponding to the cell, and the base station is a base station to which the mobile communication terminal is to be connected; when the modem starts the network search, the mobile communication terminal combines itself. The frequency band support capability obtains a specific frequency band array according to the frequency band searched by the current network, and the frequency band array is an array of frequency bands obtained by the mobile communication terminal searching the network.

Step 220: Query the corresponding carrier aggregation combination information according to the frequency band array.

The mobile communication terminal stores carrier aggregation combination information of all frequency bands supported by each operator of the mobile communication terminal, configuration information of the carrier aggregation combination information, radio access technology of each operator, and sequence of network search by the mobile communication terminal. And generating a band carrier aggregation mapping list of carrier aggregation combination information according to all frequency bands supported by the mobile communication terminal, where the band carrier aggregation mapping list includes a mapping relationship between a frequency band supported by the mobile communication terminal and carrier aggregation combination information, and is obtained according to the mobile communication terminal search network. The frequency band array queries the corresponding carrier aggregation combination information from the frequency band carrier aggregation mapping list.

Step 230: Generate radio frequency capability information according to the frequency band array and the corresponding carrier aggregation combination information.

The mobile communication terminal queries the corresponding carrier aggregation combination information from the frequency band carrier aggregation mapping list according to the frequency band array obtained by the search network, and generates radio frequency capability information, where the radio frequency capability information includes a standard supported by the mobile communication terminal, a supported frequency band, and a supported carrier. Aggregation capability information, the carrier aggregation capability information refers to an array of frequency band components obtained by the mobile communication terminal according to the current network search, and the corresponding carrier aggregation combination information is queried from the frequency band carrier aggregation mapping list.

Step 240: Report radio frequency capability information.

When performing the attach procedure, the mobile communication terminal first needs to initiate a random access procedure, and sends a random access message to the base station. After detecting the random access message, the base station sends a random access response message to the mobile communication terminal, and the mobile communication terminal Receiving a random access response message, adjusting an uplink transmission time according to a Timing Advance (TA) value of the random access response message, and transmitting a random access request signaling RRC Connection Request message to the base station, where the base station sends a random to the mobile communication terminal The access signaling RRC Connection Setup includes the establishment of the SRB1 signaling bearer and the radio resource configuration information. Then, after completing the SRB1 bearer and the radio resource configuration according to the RRC Connection Setup signaling message, the mobile communication terminal sends the random access completion signaling RRC Connect Complete signaling to the base station, and the terminal establishes a connection with the base station. The RRC Connect Complete signaling includes an attach request Attach Request, a Public Data Networks (PDN) connectivity request, that is, a PDN connection request message.

The base station includes an attach request, a network request MME (Mobility Management Entity) according to the RRC Connect Complete signaling, and then sends an initial mobile communication terminal message Initial UE massage to the network node MME, including a non-access (Non-Access Stratum, NAS) layer.

The network node MME sends an initial context setting request message to the base station to request to establish a default bearer, where the initial context setting request message Initial Context Setup Request includes a NAS layer attach receiving request Attach Accept, and a default EPS bearer context request message Activate default EPS bearer context request.

The base station receives the initial context setting request message Initial Context Setup Request. If the radio frequency capability information is not included, the base station sends a radio frequency capability information transmission radio frequency capability query request to the mobile communication terminal to query the mobile communication terminal carrier aggregation capability. Then, the mobile communication terminal sends the radio frequency capability information to the base station according to the radio frequency capability query request, and reports the carrier aggregation capability information of the mobile communication terminal.
