In addition, for the message relating that will transmit on the Traffic Channel to node (its frequency is corresponding to the frequency of Traffic Channel), need construct the 3rd key assignments according to the channel number and the 3rd frequency point number of the Traffic Channel of carrying in the message of transmitting on the Traffic Channel.
By above-mentioned processing, the node of the signaling on the Abis interface and current calling (comprising business such as caller, called, note) can be associated, from can easily obtaining all relevant Abis interface information of this business.
Below in conjunction with the process prescription of caller processing procedure of the present invention.
The present invention proposes the method for on the Abis interface of GSM, obtaining signaling and synthetic signaling process.By this method, RSL, the DTAP message (comprising RR, MM, CC message) of MS on Abis interface can be associated, form complete signaling process.
Fig. 4 is the signaling process schematic diagram on the Abis interface in the caller process of stipulating in the relevant criterion, there is shown the process of RR layer, MM layer, CC layer connection foundation.
Based on signaling process shown in Figure 4, it is as follows that the present invention carries out the synthetic processing procedure of signaling:
At first, BTS receives (1) the Channel RQD from MS;
The first step: when receiving (2) Channel RQD message shown in Figure 4, set up host node, the ChannelNumber type of this message is Common Control Channel (Common ControlChannel, abbreviate CCCH as), and wherein have and insert (Random Access at random, abbreviate RA as) field, utilize terminal endpoint identifier (Terminal Endpoint Identifier, abbreviate TEI as)+ChanNum+RA constitutes key assignments, wherein, TEI represents the numbering of carrier frequency, and ChanNum represents channel number (channel number of CCCH);
Second step: next receive (3) Channel ACT message and (4) Channel ACTACK message, the ChannelNumber type of these two message is Separate Dedicated Control Channel (Stand-alone Dedicated Control Channel, abbreviate SDCCH as), this channel number is distributed by BSC and needs BTS specifically to support.Because it is different with the channel type of article one message (ChannelRQD message), so can't be to the host node of this calling with these two message relatings, have only etc. receive (5) Imm Ass Cmd message after, could from Imm Ass Cmd message, obtain to be the SDCCH channel number of this call distribution, and Random Access (RA) parameter, and then these two message signalings (3) and signaling (4) and current call flow associated.When receiving these two message,,, carry out association according to these two message again after waiting on the message of Imm Ass Cmd so these two message need be kept among the Map table Channel_Map because can't find the node of this calling.
Preferably, in the time of in these two message being saved in the Map table, need with ChanNum key assignments.Because Channel RQD and Imm Ass Cmd message are on the CCCH channel, and Channel ACT message and Channel ACT ACK message are on the SDCCH channel, so the frequency at signaling place might change (here, TEI can be used for identifying different frequencies), channel need be activated the frequency sign of message (above-mentioned signaling (3) and signaling (4)) preserves, and, be that key assignments is kept in the another one Map table (Freq_Map table) so this frequency is identified with ChanNum with frequency of TEI unique identification.
After the 3rd step: BSC receives (5) Imm Ass Cmd message (immediate assignment command messages, this message are channel activation confirmation message) from BTS, under the situation that the channel that distributed can be used, the channel information that distributes need be informed MS before confirming.The ChannelNumber of signaling (5) is CCCH, and has Random Access (RA).Constitute key assignments by (TEI+ChanNum+RA), Imm Ass Cmd message and Channel RQD message relating can be got up.
Then, need before Channel ACT message and Channel ACT ACK message relating are got up.As key assignments, in preserving the Channel_Map table that channel activates message before, search signaling (3) and (4) two channels activation of signaling message by the SDCCH channel number ChanNum that will carry in the Imm Ass Cmd message with this key assignments.
Preferably, because signaling after this will operate on the newly assigned SDCCH channel, and frequency may change, so key assignments need be made amendment, new key assignments is made of following mode: TEI+ChanNum, wherein ChannNum is newly assigned SDCCH channel number, and TEI is to be the new frequency sign that key assignments finds in Freq_Map with the SDCCH channel number.
After this, MS can send (6) SABM message to BTS; BTS returns (7) UA message (this message is acknowledgement frame) to MS; BTS sends (8) to BSC and sets up indication (EST IND (CM Service REQ)) message; BSC sends (9) connection request (CR (CMP L3 information)) message to MSC; MSC returns (10) to BSC and connects affirmation (CC) message, and returns professional (CM ServiceAccepted) message of accepting of (11) CM to MS; MS sends (12) to MSC and sets up (Setup) message;
The 4th step: receive signaling (13) (message (Call Proceeding message) is carried out in calling), the channel number ChannelNumber of Jie Shouing is the SDCCH channel number that distributes before before this, each all construct key assignments (in the mode of TEI+ChanNum) when receiving message, thus with these message relatings to host node.
Afterwards, MSC sends (14) assignment request (ASS REQ) message to BSC;
The 5th step: when receiving signaling (15) Channel ACT message, need be call flow distribution service channel (Traffic Channel, TCH) so that converse, signaling (15) and (16) Channel ACTACK message temporarily can't be associated with signaling before, therefore can earlier these two message be saved in ChanNum is among the Map table Channel_Map of key assignments, the frequency sign that needs simultaneously channel to be activated message (signaling (15) and (16)) is preserved, because the TEI of these two message can frequency of unique identification, so be that key assignments is kept among the Map table Freq_Map with ChanNum with this frequency sign.
The 6th step: after receiving (17) assignment messages (Ass Cmd message), because newly assigned channel also is not notified to MS, and the ChannelNumber field of Ass Cmd message itself still is original SDCCH, therefore need constitute key assignments by TEI+ChanNum, make this message signalling correlated with before.Simultaneously, the relevant information of having carried newly assigned TCH channel in this signaling,, in preserving the Map table Channel_Map that channel activates message before, search channel with this key assignments and activate message (signaling (15) and signaling (16)) as key assignments by the TCH channel number ChanNum that will carry in this message.
Preferably, because signaling after this will operate on the newly assigned TCH channel, and frequency may change, so key assignments need be made amendment, new key assignments is made of TEI+ChanNum, wherein ChannNum is newly assigned TCH channel number, and TEI is with the TCH channel number ChanNum new frequency sign that to be key assignments find in Map table Freq_Map.Simultaneously because after Ass Cmd message, have the dispose procedure of an original SDCCH channel, signaling in this process is still on the SDCCH channel, so for these message relatings, need the corresponding relation between acquisition SDCCH and the TCH, the information of having preserved SDCCH and TCH in Ass Cmd message is the node key assignments on the TCH channel that key assignments is kept in the Map table SDCCH2TCH_Map table with the node key assignments on the SDCCH channel.
The 7th step: after the TCH Channel Assignment, need SDCCH channel is before discharged, do not provide among the last figure of the release message of SDCCH channel.The ChannelNumber field of the release message of SDCCH channel still is the SDCCH channel number, so also will utilize TCH in the AssCmd message and the corresponding relation of SDCCH, channel release message is done association.With SDCCH node key assignments is that key assignments finds corresponding TCH node key assignments in SDCCH2TCH_Map, and the release message of SDCCH channel is associated with host node.
The 8th step: message after this all is to operate on the TCH channel, constitutes key assignments by ChanNum+TEI, just can with before signalling correlated.
The transmission course of message is as follows after the 8th step: MS can send (18) SABM message to BTS; BTS returns (19) UA message to MS; BTS sends (20) to BSC and sets up indication (EST IND) message; MS sends (21) appointment to BSC and finishes (ASSCMP) message; BSC sends (22) appointment to MSC and finishes (ASS CMP) message; (23) beginning ring (Alerting); MSC sends (24) to MS and connects (Connection) message; MS sends (25) to MSC and connects affirmation (Connection ACK) message; (26) (Talking) converses; MS sends (27) disconnection to MSC and (also can be described as on-hook, DISC) message; MSC sends (28) to MS and discharges (REL) message; MS sends (29) release to MSC and finishes (REL CMP) message; MSC sends (30) clear command (Clear CMD) to BSC; BSC sends (31) channel to MS and discharges (Channel REL) message; MS sends (32) disc message to BTS; BTS returns (33) UA message to MS; BSC sends (34) deactivation SACCH (Deactive SACCH) message to BTS; BTS sends (35) to BSC and discharges indication (RELIND) message; BSC sends (36) wireless channel to BTS and discharges (RF Channel REL) message; BTS sends (37) wireless channel to BSC and discharges affirmation (RF Channel RELACK) message; BSC sends (38) clear command (Clear CMD) to MSC; MSC sends (39) RLSD message to BSC; BSC sends (40) RLSD to MSC and finishes (RLSD CMP) message.
Wherein, the transmission course of the process of transmitting of message (31) to (37) and message (38) to (40) can executed in parallel.
What describe with top is the signaling synthesis mode of calling procedure, and in called flow, signaling synthesis mode and calling procedure are basic identical, and just many one goes on foot related beep-page message (Paging Cmd).When receiving beep-page message (Paging Cmd), owing to do not know that this beep-page message is relevant with which flow process, so take out Subscriber Number entrained in the current message (this number may be the IMSI number, TMSI), with this number is key assignments, and this message buffering is got up.When receiving EST IND (Paging RESP), confirm that current flow process is a called flow (comprises receive note), so according in this message with Subscriber Number, just can be associated with the beep-page message of this flow process.Other position is upgraded, and the interrelational form of the switching on and shutting down and the flow process of sending short messages is all identical with calling procedure.
To be example below with the calling procedure and describe processing procedure according to Abis mouth incident composition algorithm in the Abis interface signal processing method of present embodiment in conjunction with Fig. 5.
As shown in Figure 5, when receiving the signaling message of Abis mouth, at first judge the type of message of this message, and handle accordingly respectively according to type of message.As shown in Figure 5, the process of handling according to the type of message is as follows:
(1) Chan RQD Message Processing, when receiving Chan RQD message, a newly-built node, follow-up message need be associated with this node.
(2) Chan ACT/Chan ACT ACK Message Processing because these two message on SDCCH, are called out on the node so temporarily can't be associated with, is saved in these two message in the buffering area, and the frequency at these two message places is represented to be kept in the Map table.
(3) Imm Ass Cmd Message Processing, according to the SDCCH channel massage that distributes in this message, the channel before obtaining in buffering area activates message and channel activation confirmation message.And according to the frequency sign at these two message places, and newly assigned SDCCH channel number, construct new key assignments.
(4) Paging Cmd Message Processing, when receiving paging command message, because temporarily can't it is related with host node, be that key assignments is saved in buffering area with the Subscriber Number with paging command earlier.
(5) Paging Resp Message Processing when receiving page-response message, shows that this is a called process, then searches out corresponding Paging Cmd order according to the Subscriber Number that carries in this message in the buffering area of before preservation Paging Cmd message.
(6) Ass Cmd Message Processing, according to the TCH channel massage that distributes in this message, the channel before obtaining in buffering area activates message and channel activation confirmation message.And according to the frequency sign at these two message places, and newly assigned TCH channel number, construct new key assignments.Need simultaneously the corresponding relation of SDCCH channel and TCH interchannel is saved in the Map table.
(7) processing of Hand Det message when receiving this message, needs newly-built node, and will before be kept at Chan ACT in the buffering area and Chan ACT ACK message relating to host node.
(8) processing of RF Chan Rel Ack message, this message are that wireless channel discharges acknowledge message, if this message relating in call flow, and this message is the release message of SDCCH channel, do not need to close current node so; If this message relating in call flow, and is the release of TCH channel, need so node is closed, call flow finishes; If be associated with other flow processs, and be the release of SDCCH channel, need closed node equally.
(9) processing of other message when other message of receiving beyond the above message, at first according to the channel type and the channel number structure key assignments of this message, is sought interdependent node.If do not find interdependent node, and the channel type of this message is the SDCCH channel, then finds relevant TCH channel according to the SDCCH channel, re-constructs key assignments, seeks node once more.
By above-mentioned processing, the node of the signaling on the Abis interface and current calling (comprising business such as caller, called, note) can be associated, from can easily obtaining all relevant Abis interface information of this business.
