Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of system access method, communication system, user terminal and network equipment.
Background technology
Carrier aggregation, i.e. carrier aggregation, its basic principle is to make the work that condenses together of two or more main carrier, thereby satisfies higher bandwidth demand.
At 3GPP Long Term Evolution (LTE, Long Term Evolution) (later release of LTE is also referred to as LTE-Advanced to the later release of technology, as LTE R10 etc.) in, carrier aggregation is as supporting that more the key technology of high bandwidth transmission is introduced into, as shown in Figure 1a, do not use the scene schematic diagram of carrier aggregation for user terminal in the LTE-Advanced system only uses carrier wave 1, Fig. 1 b uses carrier wave 1 and carrier wave 2 to carry out the scene schematic diagram of carrier aggregation for user terminal in the LTE-Advanced system.
According to prior art, when user terminal was in the residential quarter that has simultaneously a plurality of carrier waves, the process that this user terminal is linked into the LTE-Advanced system mainly comprised following three steps:
At first, user terminal was searched for the main and auxiliary synchronizing signal in the residential quarter take the scouting interval of 100kHz as synchronizing signal is searched for, and after user terminal successfully searches out synchronizing signal, had just realized synchronizeing of user terminal and cell downlink signal frequency;
then, user terminal is from broadcast channel (BCH, Broadcast CHannel) the upper cell broadcast information that receives, particularly, user terminal first receives Master Information Block (Master Information Block) from BCH, generally comprise downlink bandwidth information in this host system message block, number of transmit antennas information, PHICH channel architecture information etc., after receiving Master Information Block, further receive again other system information (SI, SystemInformation), such as, as the LTE-Advanced employing Frequency Division Duplexing (FDD) (FDD of system, (adopt the LTE-Advanced system of FDD communication pattern also referred to as FDD LTE system) during Frequency Division Dual) communication pattern, user terminal can also further receive FDD LTE system information SI, and as the LTE-Advanced employing time division duplex (TDD of system, (adopt the LTE-Advanced system of TDD communication pattern also referred to as TDD LTE system) during Time Division Dual) communication pattern, user terminal can also further receive TDD LTE system information SI,
At last, the carrier wave of the cell broadcast information that the user terminal utilization receives from BCH is linked in the LTE-Advanced system.Such as, for TDD LTE system, because the uplink and downlink signals in TDD LTE system is operated on same carrier wave, so user terminal can directly utilize the carrier wave corresponding to the TDDLTE system information that receives, and is linked in TDD LTE system; And for FDD LTE system, although the uplink and downlink signals in FDD LTE system is operated on different carrier, but the pair relationhip between the carrier wave that is operated in respectively due to the uplink and downlink signals in FDD LTE system is known, therefore user terminal also can directly utilize the carrier wave with the carrier wave pairing of the FDD LTE system information that receives, and is linked in FDD LTE system.
In the prior art, when adopting above-mentioned user terminal to be linked into method in the LTE-Advanced system, user terminal can only utilize current search to signal carrier wave or be linked in the LTE-Advanced system with the carrier wave of this carrier wave pairing, this is in blindly uncontrollable state when just making the user terminal access communication system.
