The present invention is described in further detail below in conjunction with drawings and the specific embodiments:
See also Fig. 1, this figure is depicted as the structure of the device of the realization eNB access core net in the present embodiment, comprising: network operation module, network process module, network transceiving module, Network conf iotag. module.The function of each module and relation each other are as follows:
Network conf iotag. module is used for providing the interface with user interactions, receives the set Network operation mode of user, and this Network operation mode is sent to network operation module; Also being used for carrying out signal according to the warning information that network operation module is sent shows.
Network operation module, main being responsible for communicates with eNB and network process module, the Network operation mode that sends according to Network conf iotag. module is determined the core net access way of current employing, and network process module is set accordingly, enables corresponding protocols processing module in this network process module; At up direction, when receiving the message of eNB with this message transparent transmission to network process module; At down direction, just the message transparent transmission of network process module is to eNB.
Network process module mainly is responsible for signal and is handled, and realizes the mutual conversion of signal, encoding and decoding etc.At up direction, according to the core net access way of current employing the message of eNB is carried out sending to network transceiving module after the corresponding protocol processes; At down direction, send to network operation module after opposite processing of message process with network transceiving module.This module comprises: E1 protocol process module, IP protocol process module, WiMAX protocol process module, WiFi protocol process module are respectively applied to carry out E1 protocol processes, IP protocol processes, WiMAX protocol processes, WiFi protocol processes.
Network transceiving module communicates with core net and network process module, mainly is responsible for transmission and the reception of message.At up direction, according to the Network operation mode of current employing in the future the interface of message by correspondence of automatic network processing module be sent to core net; At down direction, will pass through network process module from the message of core net.
The operation principle of said apparatus is: at first, the user arranges Network operation mode by the interactive interface that Network conf iotag. module provides, Network conf iotag. module sends to network operation module with the Network operation mode that the user arranges, accordingly network processing unit is carried out initialization by it, it is run mode that selected protocol process module is set, and being set to not selected protocol process module is slave state.In the device running, up direction, network operation module is after the message that receives the eNB transmission, according to Network operation mode (the E1 operational mode of user by the Network conf iotag. module setting, wired IP operational mode, WiMAX operational mode or WiFi operational mode) determine mode (the E1 access way of the current access core net that need to adopt, wired IP access way, WiMAX access way or WiFi access way), network process module carries out corresponding protocol processes (E1 protocol processes to above-mentioned message accordingly, the IP protocol processes, WiMAX protocol processes or WiFi protocol processes) after send to core net; When down direction, network transceiving module received the message of core net, to network process module, network process module sent to eNB by network operation module after this message is carried out corresponding protocol processes with its transparent transmission.In above-mentioned running, unusual if the network operation takes place, then network operation module can produce alarm and alarm signal is sent to Network conf iotag. module, and Network conf iotag. module is carried out corresponding signal according to alarm signal by status lamp again and shown.
See also Fig. 2, this figure is depicted as the method flow diagram of the realization eNB access core net in the present embodiment, specifically may further comprise the steps:
Step 201, eNB has message to send, and this message is given pass through network operation module.
Step 202 after network operation module receives the message of eNB, judges that the network insertion frequency of failure whether greater than default N, if greater than N, then forwards step 205 to; Otherwise, as if access failure mistake under the current network operational mode, then select the Network operation mode of acquiescence, if do not fail, then select the Network operation mode of Network conf iotag. module configuration.Judge then can inserting core net under the selected Network operation mode and (send number of times and the frequency of failure is judged according to message under this Network operation mode, equal the frequency of failure if send number of times, then expression can not insert, otherwise expression can insert), if can, then change step 203 over to, otherwise, re-execute step 202 after the current network insertion frequency of failure added 1.
In this step, the span of involved N can be set to [0,16].In actual use, if the Network operation mode that adopts is non-default mode, then N be [0,2), if default mode, then N be [0,1).Wherein, Network conf iotag. module can be come by setting network Configuration Values (four bit, 0000, expression E1 mode according to following table 1; 0001, represent wired IP mode; 0010, expression WiMAX mode; 0011, expression WiFi mode; All the other are reservation mode) Network operation mode is set.
Table 1
Numbering The network configuration value Operational mode Transmission direction Action
1 0000 E1 Up Read
2 0001 Wired IP Up Read
3 0010 WiMAX Up Read
4 0011 WiFi Up Read
5 [0100,1111] Reserve Reserve Reserve
Step 203, network process module are carried out corresponding procotol according to Network operation mode to the message of eNB and are handled.If handle successfully, the message after then will handling is sent to network transceiving module, enters step 204; Otherwise, current network insertion frequency of failure accumulative total is added 1 back execution in step 202.
In this step, when the network configuration value is 0000, indicate to adopt E1 access way (belong to line access mode is arranged), message is carried out the E1 protocol processes; When the network configuration value is 0001, indicate to adopt wired IP access way (belong to line access mode is arranged), message is carried out the IP protocol processes; When the network configuration value is 0010, indicate to adopt WiMAX access way (belonging to wireless access way), message is carried out the WiMAX protocol processes; When the network configuration value is 0011, indicate to adopt WiFi access way (belonging to wireless access way), message is carried out the WiFi protocol processes.
Wherein, be directed to E1 protocol processes and IP protocol processes, two kinds of processing modes are basic identical, E1 protocol process module and IP protocol process module all will be realized the basic function of baseband portion and radio frequency part, comprising the mutual conversion of analog signal to digital signal, the transmission of digital signal on wire transmission medium (E1 line, twisted-pair feeder, coaxial cable etc.).Be directed to the WiMAX protocol processes, the WiMAX protocol process module will be realized the basic function of baseband portion and radio frequency part, comprising analog signal to the synthetic of the transmission of the modulation on wireless carrier of the mutual conversion of digital signal, digital signal, wireless carrier and reception, aerial signal and along separate routes, functions such as the emission of wireless signal and reception.At up direction, after the WiMAX protocol process module receives the message (being baseband signal) of eNB, with this signal encode, modulation, frequency conversion, power amplification, be modulated to 2 to 66GHz frequency ranges and launch again; Wherein modulation system can be used DBPSK (binary system difference phase shift modulation keying), DQPSK (four phase relative phase shift keyings), QAM (quadrature amplitude modulation), OFDM standard modulation techniques such as (OFDMs).Down direction is the inverse process of up direction, repeats no more.The WiFi protocol process module carries out that process and the WiMAX protocol processes process of WiFi protocol processes is roughly the same, and it is different that the main distinction is to transmit and receive frequency, and the WiFi protocol process module mainly is to modulate the signal on the 2.4G frequency range.
After step 204, network transceiving module receive treated message, use corresponding interface to send a message to core net according to current Network operation mode.Judge then whether Network operation mode changes, if then enter step 205; Otherwise finish this flow process.
Step 205 is removed the network insertion frequency of failure, and the informing network configuration module upgrades network operation state.
In addition, if core net sends message to eNB, network process module is according to input, according to corresponding agreement handle (as, if WiFi receives, then carry out the WiFi protocol processes), after the processing, message is submitted to next module, all the other modules are with the message transparent transmission again, and then processing procedure is the inverse process that eNB sends message.
In the said method, can at first carry out initialization to Network operation mode, during initialization, Network operation mode is set to wired working method, namely adopts wired mode to insert core network.In network operation process, can pass through Network conf iotag. module configuration network operational mode, collocation method is as follows:
Steps A, Network conf iotag. module receive user's configuration indication (comprising the network configuration value), and it is legal to check that configuration indicates whether, if legal, then sends configuration messages to network operation module; Otherwise then Network conf iotag. module shows by status lamp, afterwards process ends.
Step B after network operation module receives configuration messages, checks whether configuration messages is legal, if illegal, then sends a warning message to Network conf iotag. module, and Network conf iotag. module shows by status lamp, afterwards process ends; Otherwise, with the value of the maximum network frequency of failure N of permission is set, according to configuration messages network process module is arranged, enable wherein corresponding protocols processing module, and the result will be set return to Network conf iotag. module.
Step C, Network conf iotag. module receives the result that arranges who returns, if success is set, then upgrades by status lamp display network running status.
Step D, in network operation process, when current network operation appearance was unusual, network operation module can send a warning message to Network conf iotag. module, and Network conf iotag. module then shows by status lamp according to the classification of warning information.Wherein, the status lamp of Network conf iotag. module, 1,2,3,4 meanings of representing respectively can reference table 2.
