Embodiment 2
In order to realize Abis interface IP transmission, improve efficiency of transmission, solve QoS transmission problem, cost saving, the embodiment of the invention provides a kind of method that realizes interface IP transmission, and this method thes contents are as follows:
Referring to Fig. 2, a kind of employing LAPD Over UDP/IP that provides for the embodiment of the invention realizes Abis interface IP signaling transmission method schematic flow sheet, referring to Fig. 3, and the mutual schematic diagram of initialization procedure of the BTS of the Abis IPization that provides for the embodiment of the invention.As shown in Figures 2 and 3, this employing LAPD Over UDP/IP realizes that the method for Abis interface IP signaling transmission comprises three processes:
At first, carry out the dhcp process between BTS and the BSC, this process realizes that mainly BSC area divides BTS, and promptly BTS is self assign logical addresses to the BSC request.Secondly, carry out the LAPD process between BTS and the BSC, this process mainly realizes setting up between BTS and the BSC LAPD link.Once more, carry out the IWF layoutprocedure between BTS and the BSC, this process mainly realizes the IWF configuration of BTS.See following explanation for details:
Wherein, because under Abis IP mode, can't distinguish BTS by physical connection, need to realize distinguishing by the electronic tag (Electronic Serial Number) of the PTU veneer among the BTS, the inventor is by using DHCP (Dynamic Host Configuration Protocol, dynamic host allocation protocol) flow process realizes that BSC area divides BTS, and promptly DHCP is used for BSC and gives BTS with information distribution such as IP address and port numbers.
Step 201:BSC carries out preprocessing process.
Wherein, this preprocessing process comprises: BSC side OMU (Operation ﹠amp; Maintenance Unit, Operation and Maintenance Unit) veneer issues the configure order of finishing BSC, BTS, sub-district and Abis link, the XPU of BSC side (X Process Unit, the signaling process veneer) after veneer is received this order, this order is forwarded to PIU (Plug in Unit, insert veneer), after the PIU veneer is received this order, (the Transfer Operation ﹠amp of the TRANOM in the PIU veneer; Maintenance) transmission Operation and Maintenance) finish ME (Micro Engine, microcode engine) IWF (Interactive Website Framework, the framework of webpage alternately) table, the DHCP Relay configuration of transmitting, and the configuration of LAPD link IWF, and return cooperation to the XPU veneer and confirm.
Wherein, the Interworking interconnection IWF table of the configuration in the PIU veneer, the data transaction that is used for transmitting on HDLC (High level Data Link Control, the High-Level Data Link Control) passage with BTS inside connects the transmission data to the UDP/IP on the AbisIP interface;
Step 202:BTS sends the DHCP request to BSC, carries the electronic tag of the PTU veneer of this BTS in this request.
Wherein, as mentioned before, because under Abis IP mode, can't distinguish BTS by physical connection, need by PTU (the Packet Transfer Unit among the BTS, the transmitted in packets veneer) electronic tag of veneer (Electronic Serial Number) realize to be distinguished, and therefore, the electronic tag that carries self PTU veneer by the DHCP request reports BSC and realizes.
Step 203:BSC receives the DHCP request, returns dhcp response to BTS, carries logic IP addresses, physical IP address, OML (the Operation ﹠amp of the PTU that distributes into BTS in this response; Maintenance Link, Operation and maintenance link) port numbers and ESL port numbers.
Wherein, at first the PIU veneer among the BSC is received the DHCP request that BTS sends, after IP protocol module in the PIU veneer carries out DHCP Relay to this DHCP request, the DHCP request is forwarded to the XPU veneer, and the operating maintenance module BTSM in the XPU veneer (BTS Maintainence, BTS maintenance module) adds DHCP Server function, at this moment, BSC serves as the DHCPServer server, and the XPU veneer returns dhcp response to the PIU veneer, and the PIU veneer is transmitted to BTS with this dhcp response.
After step 204:BTS receives dhcp response,, the PTU IP address of BTS is set, route is set, creates self inner HDLC link, and the IWF that is provided with among the PTU veneer ME shows according to the information of carrying in this dhcp response.
So far, finished the dhcp process of carrying out between BTS and the BSC.
Step 205:BTS sends LAPD ID request according to the OML passage of OML port numbers correspondence to BSC.
Wherein, because in the step 104, BTS receives and carries logic IP addresses, physical IP address, OML port numbers and ESL (the Extend Signal Link that BSC is the PTU of BTS distribution in the dhcp response, Extend Signaling Link) port numbers, so, the OML passage of the OML port numbers correspondence that this BTS distributes for self according to BSC sends Link Access Procedure on D channel sign LAPD ID request to BSC.
Step 206; After BSC receives this LAPD ID request,, fill in release type and Linktype, and return LAPD ID response, carried terminal sign TEI, release type and Linktype in this response to BTS for this BTS distributing terminals sign TEI.
Wherein, PIU veneer among the BSC receives that BTS passes through the LAPD ID request of the OML passage transmission of OML port numbers correspondence, ME in the PIU veneer carries out route querying to UoIP (Universal Over IP by IWF, unified protocols over IP, be used for the inner communication between plates of controller) sign (corresponding) with the mapping of OML channel number, and the LAPD ID request that will carry the UoIP sign is forwarded to the XPU veneer among the BSC, at this moment, based on LAPD, BSC can identify according to UoIP, search corresponding BTS, be this BTS distributing terminals sign TEI, fill in release type and Linktype, the XPU veneer among the BSC returns LAPD ID response, carried terminal sign TEI in this response, fill in release type and Linktype, the PIU veneer is forwarded to BTS with this response after receiving this LAPD ID response.
Further, according to system's needs, BTS can also send the LAPDID request to BSC according to the ESL passage of ESL port numbers correspondence; And receive the LAPD ID response that BSC returns by the ESL passage, processing procedure and above-mentioned OML channel types seemingly, present embodiment is for convenience of explanation, be that example is carried out only with the OML passage, those skilled in the art can know that the disposition of ESL passage and OML channel types seemingly repeat no more.
So far, finished the LAPD process of carrying out between BTS and the BSC.
The OML passage of step 207:BSC by distributing for this BTS sends the request of the inner HDLC link establishment of BTS to BTS.
Wherein, the XPU veneer among the BSC issues HDLC link establishment request (order), and this HDLC link establishment request is forwarded to BTS through the PIU veneer by the OML passage for the OML port numbers correspondence of BTS distribution before.
After step 208:BTS receives this HDLC link establishment request by the OML passage of OML port numbers correspondence, finish the establishment of the HDLC link of self inside, and return the response of HDLC link establishment to BSC by the OML passage.
Wherein, the PTU veneer of BTS is finished the establishment of inner HDLC link between this PTU veneer and the BTMU veneer after receiving this HDLC link establishment request.And return HDLC link establishment response to BSC by the OML passage, this response is used to confirm BTS side HDLC link establishment.
After step 209:BSC receives the response of HDLC link establishment,,, carry LAPD and UDP/IP mapping relations in this request to the configuring request that BTS sends the IWF table by the ESL passage that distributes for this BTS.
Wherein, the configuration of so-called IWF table is meant the LAPD and the UDP/IP mapping relations of above-mentioned foundation. can be in order to realize BSC according to the UDP/IP five-tuple (agreement in the UDP/IP message packet that receives, local address, local port number, way address far away, port numbers far away) inquiry obtains specific LAPD link, has defined following LAPD and UDP/IP mapping relations:
(1) for speech business, to UDP/IP connection of each channel creation of speech business, wherein, channel comprises full speed channel or half-rate channel; Wherein, when the channel of speech business is full speed channel, creates a UDP/IP for this full speed channel and connect; When the channel of speech business is half-rate channel, creates a UDP/IP for this half-rate channel and connect;
For example, creating a UDP/IP for each half-rate channel of each carrier frequency in BTS calling access procedure connects, BSC sends configuration messages (comprising the UDP/IP five-tuple that distributes for this half-rate channel in advance) and gives BTS, the foundation that BTS finishes the inner passage returns to BSC afterwards and with the UDP/IP five-tuple, and BSC finishes the mapping table of UDP/IP five-tuple and half-rate channel.
(2) for Packet Service, each carrier frequency of this Packet Service is created a UDP/IP connect, be used to carry the grouped data on the whole carrier frequency.
For example, creating a UDP/IP for the carrier frequency that comprises packet traffic channel connects, BSC sends configuration messages (comprising the UDP/IP five-tuple of giving this carrier frequency distribution) and gives BTS, BTS finishes the foundation of inner passage and the UDP/IP five-tuple is returned to BSC, and BSC finishes the configuration of inner UDP/IP and LAPD mapping table.
Step 210:BTS receives the configuring request of IWF table, finishes the configuration of IWF table, and returns the configuration response of IWF table to BSC by the ESL passage.
So far, finished the layoutprocedure of the IWF table of carrying out between BTS and the BSC.
Step 211:BTS carries out initialization procedure.
Wherein, after adopting LAPD Over UDP/IP to realize the transmission of Abis interface IP signaling, initialization procedure and prior art that BTS carried out are similar, repeat no more.
Step 212:BSC initiates the foundation of EML passage according to the indication of BTS ability, and sends LAPD SABME (Set Asynchronous Balanced Mode Extended is provided with Asynchronous Balanced Mode expansion frame) frame by the EML passage to BTS.
Wherein, because when setting up the LAPD connection, LAPD SABME frame is first frame that is sent out normally, after transmission finishes this SABME frame, the beginning multiframe confirms pattern, after receiving terminal is received this LAPD SABME frame, does not have confirmed frame to be left in the basket in the past.
Step 213:BTS receives LAPD SABME frame, returns LAPD UA (Unnumbered acknowl edgement, unnumbered is confirmed) frame by EML (Extend Maintainence Link, the maintenance link of expansion) passage to BSC.
Wherein, because when setting up the LAPD connection, this LAPD UA frame is used for BTS is successfully received the information announcement of this LAPD SABME frame to BSC as the response of LAPD SABME frame.
To sum up, by foregoing, finished the foundation (the LAPD link is the OML passage, has promptly finished the foundation of OML passage) of LAPD link, this OML passage has following effect: (1) obtains the configuration parameter of service operation; (2) obtain the version updating of BTS; (3) transmit OAM (Operation Administration Maintenance, operation management maintain) order.TMU veneer among the BTS (Timing/Transmission and Management Unit, regularly/Transmission and Management Unit) behind normal the startup, can attempt setting up OML passage (being the LAPD link) always, after OML passage overlap joint is finished, the TMU veneer gets access to the service operation configuration parameter, and this moment, the TMU veneer just can make the TRU single board starting.
Referring to Fig. 4, the OML access diagram that provides for the embodiment of the invention.After the establishment of OML passage finishes, BSC can send to TMU veneer among the BTS by the OML passage with configuration informations such as base station, sub-district, carrier frequency, links, the TMU veneer receives that the BTSM veneer of giving among the BTS after these message handles, and finishes the configuration of base station initialization, cell initialization, carrier frequency initialization and link.
Referring to Fig. 5, the RSL access diagram that provides for the embodiment of the invention, after having set up the OML passage, need set up the RSL link when carrying out the IP transmission, the process of setting up and the OML link establishment process of this RSL passage are similar, repeat no more, but since IP tunnel set up in the process and finished at the OML passage, so in RSL link establishment process, then do not need above-mentioned meeting that configuration informations such as base station, sub-district, carrier frequency, link are sent to TMU veneer process among the BTS by passage.
In sum, after realizing the transmission of Abis interface IP signaling by above-mentioned employing LAPD Over UDP/IP, after base station BTS is finished initialization, just can realize BSC and BTS based on this Abis interface IP transmission, as the edition upgrading software loading that realizes Abis interface IP transmission BTS down/or the daily record warning information of BTS transmit.
Further, in order to make BSC can support the compatibility of various BTS versions, require BSC still to use LAPD SAMBE frame to carry out link setup, after starting, BTS use TEI ID Req frame to survey, inform the protocol type of BTS by BSC, if BTS supports LAPD to optimize then uses SM to finish the link link setup, and request also is set to supported protocol optimization type with other LAPD such as RSL, thereby guarantee that method that the embodiment of the invention provides can realize the compatibility of BSC and BTS, reduces and safeguards and upgrade cost.
Further, because the IP transmission network, except packet loss, time delay, shake, under scenes such as link switchover, also out of order situation can appear, and out of order in order effectively to avoid transmitting, following method has been proposed, referring to as follows:
Mode one, improve retransmission efficiency by increasing the selective repeat srej frame.Guarantee normal transmission.
Wherein, at reducing the bottom error rate, proposed to improve retransmission efficiency by increasing the selective repeat srej frame to the influence of LAPD efficiency of transmission.
Mode two, by add one deck buffering adaptation layer at the LAPD bottom, the buffering adaptation layer that this increases newly is used for the out of order bag that receives is increased suitable time delay, and then gives the LAPD protocol module and handle.
Wherein, for example, current time is received packet N, the next packet N-1 that constantly receives, by the buffering adaptation layer that the embodiment of the invention provides this packet N that receives is carried out time delay processing, after waiting for that packet N-1 disposes, give the LAPD protocol module by this buffering adaptation layer with packet N again and handle.
Mode three, the GTPU agreement of passing through to add on UDP on the interface single plate, it is that the UDP/IP packet adds the GTPU sequence number that this GTPU agreement is passed through, thereby eliminates the out of order situation that UDP/IP may bring.
If it is not under the very high application scenario that mode four requires for data packet disorder, can also adopt the mode that out of order packet is abandoned re-transmission.
By said method,, effectively avoid transmitting out of order when out of order situation occurring.
Further, in based on this Abis interface IP transmission course, delay variation may change, and need detect parameters such as time delay automatically and be used to then adjust the transmission receive window of LAPD so that keep certain transmission bandwidth.In order to support to detect loopback time-delay and shake automatically, control the out of order frame number of LAPD link, the inventor has also proposed according to loopback delay, adjusts the method for send window, and referring to Fig. 6, this method thes contents are as follows:
Step 601:BTS and BSC safeguard a time sequence number LAPD_TSN.
Wherein, BTS and BSC safeguard sequence LAPD_TSN at the same time as the LAPD entity, and this LAPD_TSN is approximately 32bit, are used for express time information (precision can be 1ms);
Step 602:BSC regularly sends synchronization frame TIME_SYN to BTS, and wherein, this TIME_SYN clock has comprised 3 time T 1, T2 and DeltaT, wherein DeltaT=T3-T2;
Wherein, the LAPD transmitting terminal (BSC) that provides referring to Fig. 7 and the mutual schematic diagram of LAPD receiving terminal (BTS) are supposed regularly (for example can be set at every 5s and send once) as the transmitting terminal of LAPD, send synchronization frame TIME_SYN.Wherein, T1 is the time that BSC sends TIME_SYN, and T2 is the time that BTS receives the TIME_SYN of BSC transmission, and T3 is BTS returns time from the TIME_SYN response to BSC.
After step 603:BTS receives synchronization frame TIME_SYN, return the TIME_SYN response to BSC.
After step 604:BSC receives the TIME_SYN response that BTS returns, computational scheme loopback delay, descending shift time, up shift time.
Wherein, receive the time T 4 of TIME_SYN response, the time T 1 that BSC sends synchronization frame TIME_SYN according to BSC, and DeltaT, calculate the line loopback time delay, with reference to as follows:
Line loopback time delay Tr=T4-T1-DeltaT;
Wherein, send the time T 1 of TIME_SYN, the time T 2 that BTS receives TIME_SYN, calculate descending shift time according to BSC, with reference to as follows:
Descending shift time Tod=T2-T1;
Wherein, receive the time T 4 of TIME_SYN response, the time T 3 that BTS sends the TIME_SYN response, calculate up shift time according to BSC, with reference to as follows:
Up shift time Tou=T4-T3;
Step 605: mutual according to double TIME_SYN, detect the up-downgoing shake.
Wherein, up shake Tju=ABS ((T1 '-T1)-(T2 '-T2)); Descending shake Tjd=ABS ((T4 '-T4)-(T3 '-T3)).When actual count is shaken,, need repeatedly ask average treatment in order to improve the precision of calculating.
Step 606:BSC adjusts send window, and informs the BTS receive window according to loopback delay.
Wherein, LAPD adjusts send window according to loopback delay, the receive window of informing BTS by the affirmation Config frame of BSC.
By said method, when in Abis interface IP transmission course, delay variation occurring, effectively guaranteed certain transmission bandwidth by the transmission receive window of adjusting LAPD.
In sum, the method of the realization Abis interface IP transmission that the embodiment of the invention provides, after adopting LAPD Over UDP/IP to solve the transmission of Abis interface signaling, realize Abis interface IP transmission, improve efficiency of transmission, solve QoS transmission problem, cost saving, and solved the problem that LAPD optimization back Abis interface BTS starts, also solved when carrying out the IP transmission after LAPD optimizes, prevent the problem of data packet disorder, realized that also LAPD optimizes the back and adjusts send window according to loopback delay.
