Description

A kind of radio data cut-in method and equipment

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.

To sum up, honeycomb mobile operator need find out low cost, and high power capacity is fit to the solution that the indoor wireless data insert.2 kinds of main solutions are at present:

1, in recent years, increasing operation has been adopted WLAN based on unauthorized frequency range (WLAN has also been claimed WiFi; WiFi:Wireless Fidelity, adopting wireless fidelity technology) system carries out the professional method of focus streamed data.Fig. 3 is WLAN+3G solution sketch map, and is as shown in the figure, and its major programme is the scheme of wlan system and the loose coupling of 3G system, is implemented in net authentication of the 3G system core and charging, and its enforcement frequency range and personal WiFi are in same frequency range.

Adopt WiFi to carry out hot zones and cover, can play data service shunting action preferably.

Adopts WiFi to carry out the hot zones data distribution, can play certain data service shunting action, but owing to be different standards system and the systems of two covers, its deficiency is:

Poor user experience, the network that generally needs the manual selection of user to insert is difficult to realize professional taking over seamlessly between two Access Networks.

Link-quality can not be guaranteed, and what WiFi adopted is unauthorized ISM (Industrial ScientificMedical, industry, science, medical treatment) frequency range, has as personal WiFi the interference between the various devices such as microwave oven.

Multi-operator networking simultaneously difficulty, because its working frequency range is unauthorized frequency range, a plurality of operators are when the same area networking, if there is not good coordinating and unifying planning, with causing mutual interference.

2, Home eNodeB (Femto; Femtocell formula base station) as solving other a solution indoor and hot zones data service flow demand, indoor distances is shorter according to covering, the characteristics that number of users is less; Reduce the capacity requirement and the merit emissivity at single station; Usually number of users is at 8-20, and power and mobile phone terminal are suitable, generally below 23dBm.Fig. 4 is LTE (Long Term Evolution, a Long Term Evolution) Femto network architecture sketch map, and the framework of employing Femto scheme can be referring to shown in Figure 4.

The relative indoor covering system of Home eNodeB and little base station, cost is lower, dispose more flexible, the effect of business experience of having played certain indoor data.

But its deficiency be not optimized to indoor data service characteristics with: Home eNodeB Femto; With LTE is example; LTE Femto system has adopted complete protocol infrastructure of LTE and Interface design basically; So the complicacy of realization, just base station capacity and power reduce, so cost is high always;

In addition; Femto is IMT (International Mobile Telecommunications; International mobile telecommunication) equipment in the system; Its frequency that can work is appointed the right mandate frequency range of the operator in the IMT that is, the bandwidth that relative WiFi can use is less, can't satisfy operator's data service shunting demand fully.

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.

IP layer processing module under family's scene also need realize routing function, realizes the directly function through equipment such as cable data transmission network or ADSL and the interconnected transmission of Internet of IP packet.

In the enforcement, radio-frequency module can also be further used for UE when eating dishes without rice or wine to transmit data, use lower transmitting power to send data to UE, use lower sensitivity to receive the data that UE sends.

Concrete, the function of radio-frequency module is the emission of realization base station equipment downlink data signal and the receiving function of upstream data. signals.Because in the main covering chamber of NDA equipment and hot zones, so it is lower to possess the descending power requirement, last line sensitivity requirement is lower, radio-frequency filter and out-of-band radiation requirement such as suitably loosen at characteristics, are beneficial to reduce equipment cost.In the enforcement, lower transmitting power can be 20dBm or 23dBm, the i.e. low-power close with the transmitting power of existing mobile phone terminal, and this is low for the traditional base station.

Configuration reference symbol still less.

Concrete; The physical layer process module can adopt the coding and decoding of LTE OFDM physical layer key technologies such as (Orthogonal FrquencyDivision Multiplexing, OFDMs) realization data-signal, modulation; Multi-antenna transmitting is defeated, functions such as link circuit self-adapting and re-transmission.Under be about to be transferred to radio frequency after MAC layer data bag is handled through a series of signal, on be about to radiofrequency signal and receive the back and form MAC layer data bag.In order to reduce equipment cost, improve efficiency of transmission, be fit to indoor transfer of data, the LTE physical layer can reduce the defeated pattern of multi-antenna transmitting relatively, disposes the more measurement and the feedback of large period, configuration control channel and reference symbol still less.

Because traditional GSM is to more than 3 kilometers/hour, the translational speed design below 250 kilometers/hour, its channel fading is very fast, and therefore measuring the level and smooth cycle is tens～hundreds of millisecond; In the enforcement, to the Terminal Design that low speed under the indoor focus scene moves, measuring the level and smooth cycle can be several seconds even longer cycle.

The control channel number is relatively more responsive to the number of users that system supports, in therefore implementing, the number of users in the system can reduce at least one one magnitude than traditional LTE system, so control channel can adopt minimum or near the configuration of minimum.

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.

Signaling control module 705, be used for UE when eating dishes without rice or wine to transmit data, when carrying out Radio Link control, by perhaps its combined treatment of one of following mode with RRM control:

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;

Simplify existing RRC to ambulant management;

Simplify existing RRC to connecting the management of setting up;

Simplify the management of existing RRC to measuring.

Concrete; The signaling control module realizes the control of Radio Link and the functions such as management control of Radio Resource; Specifically comprise the random access procedure and the access control that realize reducing step; The system information broadcast of simplifying (comprising parameters such as NDAP Radio Access Network sign, pilot tone and main channel configuration), to the simple transmission mode configuration in terminal, function such as configuration is measured and reported to necessary adjacent area and terminal signaling.Owing to some are arranged about the cell scenario parameter relevant in the existing broadcast message, and the parameter channel configuration of bringing thus with mobility; Consider characteristics, therefore can simplify, remove certain applications scene and mobile relevant parameter system information to indoor focus scene and Hypomobility.In addition; Original RRC (Radio ResourceControl; Radio Resource control) relevant signaling plane control can realize that processes such as the measurement that RRC mainly solves, mobility, connection foundation can be simplified, and also are in the signaling control module; The management that the existing RRC of simplification sets up and measures mobility, connection etc.; Such as reducing to real-time Testing requirement (comprising cycle, thresholding etc.), reduce the measurement triggering incident, simplify mobile management (low speed moves to trigger under the scene and switches lessly, also can adopt spaced antenna to reduce the handover trigger number of times consciously, and the channel that replaces in each sub-district of uniformity is reshuffled).

Data transmission interface 706 is used to NDA base station equipment and Internet or NDA gateway, and the physical link transmission is provided during the communication of LTE core net, is the final gateway of various logic interface and data channel.

In the enforcement, radio-frequency module can also be further used for sending broadcast message, will after being packaged into IP protocol data bag, be sent to internet and/or core net in order to the designation data business.

Concrete, radio-frequency module can be broadcasted the broadcast message by the indication of signaling control module.

Based on same inventive concept; A kind of radio data cut-in method also is provided in the embodiment of the invention; Because the principle that this method is dealt with problems is similar with wireless access network equipment, so the enforcement of this method can repeat part and repeat no more referring to the enforcement of wireless access network equipment.
