By above-mentioned processing, the node of the signaling on the Abis interface and current calling (comprising the 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 obtaining signaling and synthetic signaling process at the Abis interface of GSM.By the 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, referred to as CCCH), and wherein with accessing at random (Random Access, referred to as RA) field, utilize terminal endpoint identifier (Terminal Endpoint Identifier, referred to as TEI)+ChanNum+RA consists of 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, referred to as SDCCH), this channel number is distributed by BSC and needs BTS specifically to support.Because different from the channel type of article one message (ChannelRQD message), so can't be with these two message relatings to the host node of this calling, only have 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 this two message, because can't find the node of this calling, so these two message need to be kept among the Map table Channel_Map, carry out association according to these two message again after waiting on the message of Imm Ass Cmd.
Preferably, in the time of in these two message being saved in the Map table, need to be take ChanNum as 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), the frequency sign that channel need to be activated message (above-mentioned signaling (3) and signaling (4)) preserves, and with frequency of TEI unique identification, so this frequency sign is kept at take ChanNum as key assignments in the another one Map table (Freq_Map table).
The 3rd step: BSC receives (5) Imm Ass Cmd message (the immediate assignment command messages from BTS, this message is channel activation confirmation message) after, in the situation that the channel that distributed can be used, the channel information that distributes need to be informed MS before confirming.The ChannelNumber of signaling (5) is CCCH, and with Random Access (RA).Consist of 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 before channel and activate the Channel_Map table of message, search signaling (3) and (4) two channels activation of signaling message with this key assignments by the SDCCH channel number ChanNum that will carry in the Imm Ass Cmd message.
Preferably, because signaling after this will operate on the newly assigned SDCCH channel, and frequency may change, so key assignments need to be made amendment, new key assignments is made of following mode: TEI+ChanNum, wherein ChannNum is newly assigned SDCCH channel number, and TEI is the new frequency sign that finds in Freq_Map take the SDCCH channel number as key assignments.
After this, MS can send to BTS (6) SABM message; 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 SDCCH channel number that the channel number ChannelNumber that receives before this distributes before being, all construct key assignments (in the mode of TEI+ChanNum) during each receipt 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 to be call flow distribution service channel (Traffic Channel, TCH) in order to converse, signaling (15) and (16) Channel ACTACK message temporarily can't be associated with signaling before, therefore can first these two message be saved among the Map table Channel_Map take ChanNum as key assignments, the frequency sign that needs simultaneously channel to be activated message (signaling (15) and (16)) preserves, because the TEI of these two message can frequency of unique identification, so this frequency sign is kept at take ChanNum as key assignments among the Map table Freq_Map.
The 6th step: after receiving (17) assignment messages (Ass Cmd message), because newly assigned channel is not also notified to MS, and the Channel Number field of Ass Cmd message itself or original SDCCH, therefore need to consist of key assignments by TEI+ChanNum, make signalling correlated with before of this message.Simultaneously, the relevant information of having carried newly assigned TCH channel in this signaling,, in preserving before channel and activate the Map table Channel_Map of message, 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 to be made amendment, new key assignments is made of TEI+ChanNum, wherein ChannNum is newly assigned TCH channel number, and TEI is the new frequency sign that finds in Map table Freq_Map take TCH channel number ChanNum as key assignments.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 shown the node key assignments on the TCH channel in the SDCCH2 TCH_Map table as key assignments is kept at Map take 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 upper figure of the release message of SDCCH channel.The ChannelNumber field of the release message of SDCCH channel or SDCCH channel number so also will utilize TCH in the AssCmd message and the corresponding relation of SDCCH, are done association with channel release message.Take SDCCH node key assignments as key assignments finds in SDCCH2TCH_Map corresponding TCH node key assignments, 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, consists of 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 to BTS (18) SABM message; 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 (ASS CMP) 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 (3 5) 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 above part was described 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, take out entrained Subscriber Number (this number may be the IMSI number, TMSI) in the current message, take this number as key assignments, 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 switching on and shutting down and the flow process of sending short messages is all identical with calling procedure.
The below will be as an example of calling procedure example and in conjunction with the processing procedure of Fig. 5 description according to Abis mouth event composition algorithm in the Abis interface signal processing method of present embodiment.
As shown in Figure 5, when receiving the signaling message of Abis mouth, at first judge the type of message of this message, and process accordingly respectively according to type of message.As shown in Figure 5, the process of processing 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 to 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, first paging command is saved in buffering area take Subscriber Number as key assignments.
(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 so to close current node; 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 equally closed node.
(9) processing of other message when other message of receiving beyond the above message, at first according to 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, again seeks node.
By above-mentioned processing, the node of the signaling on the Abis interface and current calling (comprising the business such as caller, called, note) can be associated, from can easily obtaining all relevant Abis interface information of this business.
