nullStep S1208: owing to portfolio increases，Base station configures carrier aggregation to terminal 2 according to measurement report，Find that community 3 signal quality is good，And community 3 belongs to frequency band 41，Community 2 belongs to frequency band 38 and 41，Terminal supports the frequency band intercarrier polymerization of frequency band 41，Determine configuration community 3，The band information sent by original cell in broadcasting due to the system message of community 2 is 38，Community 2 service band 38 that terminal 2 is resident，And give tacit consent to terminal and support that the band information in system message comes into force，First can change service band 38 into 41，In order to avoid information revises the impact brought to other-end，Base station sends RRC reallocation message to terminal 2，Namely the system message of amendment community 2 needs to update by the System information block 1 of specific messages notice terminal 2 community 2，Frequency band 41 is sent by original cell，And by other cell instruction terminal，In this special System information block 1, new band information comes into force at once.
Step S1210: terminal 2 receives the dedicated system message arrangement of base station, and comes into force according to instruction, community 2 service band 41 that now terminal 2 is resident.
Step S1212: base station configures community 3 to terminal 2 and carries out carrier aggregation.
Step S1214: terminal 2 receives the configuration of base station, adopts community 2 and community 3 to carry out frequency band intercarrier polymerization, base station carries out data transmit-receive by carrier aggregation.
Wherein, in step S1210, the cell that comes into force at once of new band information in instruction terminal system message, is a newly-increased independent cell, it is possible to identified by a bit, and terminal comes into force after receiving band information new in the system message received.
In order to simplify process, the System information block 1 comprising subdistrict frequency band information can be processed as entirety, namely the ability information of terminal to report comprises the ability whether supporting that System information block 1 comes into force, base station is further processed according to terminal ability information, the cell that instruction terminal system message blocks 1 comes into force at once, being a newly-increased independent cell, it is possible to identified by a bit, terminal comes into force after receiving the System information block 1 received.
Embodiment two
In the present embodiment, terminal can support that the band information in system message comes into force, it is also possible to does not support.
Terminal 2 resides in community 2, and in broadcasting due to the system message of community 2, the band information sent by original cell is 38, community 2 service band 38 that therefore terminal is resident.Figure 13 is the second carrier aggregation flow chart according to embodiments of the present invention, and as shown in figure 13, this flow process comprises the steps:
Step S1302: terminal 2 initiates RRC connection establishment process in community 2, and enters connected state.
