Description
Technical field
The present invention relates to wireless communication technology, particularly a kind of radio data cut-in method and equipment.
Background technology
In recent years, along with popularizing of mobile Internet (Mobile Internet) and smart mobile phone, the mobile data traffic demand rapidly increases.Fig. 1 is the global data flow sketch map that predicts the outcome, and company of Cisco (Cisco) finds that as shown in Figure 1, from 09 year to 14 years, traffic growth reached 40 times after to the volume forecasting of 2009-2014 mobile data services, annually basically increases by 1 times.
Fig. 2 increases and operator's income increase trend sketch map for data service; At present, the data service ratio increases gradually in the carrier network, and it is professional to have influenced the conventional telecommunications level; But; As shown in Figure 2, because data service is according to charge on traffic, its profit growth rate and flow load are not directly proportional.
Indoor and hot spot data service feature for the user be generally fixing perhaps very low speed move, less demanding to mobility; On the other hand, data service is mainly based on the Internet of IP (Internet Protocol, Internet Protocol) professional, and is more single to the requirement of QoS (Quality of Service, service quality), and well below the requirement of carrier class business to QoS.Traditional cell mobile communication systems mainly towards be high-speed mobile, the professional design of the carrier class of seamless switching, when it carried big flow low speed IP data packet traffic, efficient was on the low side, cost is too high.

Fig. 7 is the wireless access network equipment structural representation, and is as shown in the figure, and wireless access network equipment also is can comprise in the NDA base station:
Radio-frequency module 701 is used for after the data service request of accepting the UE initiation, receives UE according to the data of 3GPPLTE agreement through eating dishes without rice or wine to send;
IP layer processing module 702 is sent to internet and/or core net through data transmission interface after being used for the data encapsulation that receives become IP protocol data bag.
In the enforcement, IP layer processing module is sent to internet and/or core net through data transmission interface through gateway after can also being further used for the data encapsulation that receives become IP protocol data bag; Or, directly be sent to internet and/or core net through data transmission interface.
In the enforcement, IP layer processing module can also be further used for UE when eating dishes without rice or wine to transmit data, compare with the requirement of LTE RLC (Radio Link Control, Radio Link control) layer standard, by one of following mode or its combined treatment:
Reduce the re-transmission pattern;
Reduce the head compression of PDCP (Packet Data Convergence Protocol, packet data polymerized agreement) layer;
Reducing packet encrypts.
Concrete, descending realizations of IP layer processing module IP packet segmentation, and the affirmation of packet retransmits pattern, the cascade and the reorganization of up realization MAC (Media Access Control, medium access control) packet, and function such as affirmation re-transmission pattern.Since only support the QoS transfer of data of simplification, relative LTE, and the rlc layer of NDA system has reduced the re-transmission pattern, and has reduced the compression of PDCP layer head, the function of aspects such as packet encryption.

Concrete, scheduling and the transmission and the re-transmission etc. of the descending realization rlc layer of MAC layer processing module packet, up realization user scheduling, MAC decoded packet data and re-transmission etc.Traditional relatively LTE system, the MAC layer has been simplified control and the scheduling of QoS, has reduced the number of users requirement that system call is supported, has simplified relevant protection and the operation in the transmission of data packets, thereby has improved the efficient of transmission, reduces the equipment cost requirement.
Reduce the number of users requirement that system call is supported; Usually the capacity of the design of LTE base station all is to support hundreds of even thousands of user simultaneously, considers indoor focus distribution scene, and area coverage is little; Number of users is less; 4~20 users possibly be typical scenes, even the enterprise-level scene at most also just supports tens users simultaneously online, therefore can reduce the number of users requirement that system call is supported.
In the enforcement, when the control of simplifying QoS and scheduling, for example can remove TTI Boundling.
In the enforcement, can further include in the wireless access network equipment:
Reduce the step in the random access procedure;
Reduce the step in the access control process;
The system information that broadcasting is simplified;
The simple configuration traffic pattern;
