And receiving data and/or control information of the user equipment on the uplink. Similarly, the UE transmits data and/or control information for the base station on the uplink and receives data and/or control information transmitted by the base station on the downlink.

In the prior art, the base station can perform access control on the UE in the idle state, where the UE will allocate an access level (English full name: Access Class, abbreviated as AC), and the level can be 0 to Any of the 9 levels, for some special users, will also be assigned one or more ACs with access levels 11 to 15, which are stored in the UE's customer identification module (English full name: Subscriber Identity Module, The abbreviation is: SIM), the base station can use the AC of the UE in the idle state to perform access control on the UE, and the access control mechanism of the UE currently in the idle state is mainly the access control prohibition (English full name: Access Control Barring) , abbreviated as: ACB) mechanism, under the ACB mechanism, the base station can broadcast ACB parameters by broadcast, as follows:

AC-BarringConfig :: = SEQUENCE!

ac-BarringFactor ENUMERATED {

OO, p05, lO, pl5, p20, p25, p30, p40 P50, p60, p70, p75, p80, p85, p90, p95 } ac-BarringTime ENUMERATED {s4, s8, sl6, s32, s64, sl28, s256, s512}

ac-BarringForSpecial AC BIT STRING ( SIZE ( 5 ) ) }

The above is the structure of the ACB parameter, where the ac-BarringFactor parameter is applicable to the UE with the AC being 0 to 9. For the UE with the AC of 11 to 15, it is necessary to see whether the bit corresponding to the ac-BarringForSpecial parameter is set to 1, and If the corresponding bit is set to 1, it is necessary to further determine whether to prohibit access of the UE. Specifically, for a UE with an access level of 0-9, or an AC with a corresponding bit set to 1 is 11 to 15. UE, this type of UE will generate a random number in the range of 0 to 1, and compare it with the corresponding value in the ac-BarringFactor parameter in the ACB parameter broadcast by the base station, if the generated random number is higher than the ac-BarringFactor parameter If the corresponding value is in the middle, it is considered that the access request of the UE is forbidden, and the time is waited according to the time in the ac-BarringTime parameter in the ACB parameter, and the UE tries again after the end of the waiting; if the generated random number is less than or If the value is equal to the corresponding value in the ac-B arringFactor parameter, the UE is considered to be not prohibited from accessing.

However, in the prior art, only the access control mechanism for the UE in the idle state, specifically the access control mechanism described above, does not have an effective access control mechanism for the UE in the connected state. , affecting the performance of the system.

Management Entity, abbreviated as: MME) AC, which refers to the AC of the UE that has accessed the cell under the jurisdiction of the base station. Specifically, in the process of the UE attaching to the network side, the UE sends all the ACs of the UE. After the MME is established, and the UE establishes an RRC connection, the MME sends the AC of the UE to the base station. Alternatively, the UE may also directly feed back the AC of the UE to the base station in the RRC connection establishment process.

In the embodiment of the present invention, the base station may obtain the AC of the UE that has accessed the cell under the jurisdiction of the base station by using any one of the foregoing two manners.

When the base station performs access control on the UE in the connected state, the UE sends a release notification according to the AC in the connected state, so that the UE in the connected state can determine according to the received release notification. Whether to release the RRC connection of the UE in the connected state.
