Embodiment
The embodiment of the invention provides a kind of method for holding business and communication system and relevant device, is used to improve user experience.
At first the communication process in the embodiment of the invention is described:
See also Fig. 1, the communication process in the embodiment of the invention comprises:
The data of signaling plane are passed through BSC, MGW, and MSC server and PSTN transmit between mobile subscriber and fixed-line subscriber, and then by BSC, MGW and PSTN transmit between mobile subscriber and fixed-line subscriber user side data.
Below the method for holding business in the embodiment of the invention is described in detail, the method for holding business in the embodiment of the invention can specifically be divided into following two classes:
One, send the 2nd IT message by signaling transfer network element simulation chain of command network element to access network element:
At first need to prove, in present embodiment and subsequent embodiment, all with the example of MGW as signaling transfer network element, with the example of MSC server,, be understandable that with the example of BSC as access network element as the chain of command network element, in actual applications, along with the difference of application network, each concrete network element can also be other alternative network element, does not do qualification herein.
In the present embodiment, when the MSC server breaks down, replace the MSC server to send the 2nd IT message to BSC by MGW, then from the angle of BSC, the MSC server does not break down, thereby can keep the user side data communication.
Specifically see also Fig. 2, method for holding business first embodiment comprises in the embodiment of the invention:
201, signaling transfer network element receives the IT message that access network element sends;
For ease of understanding, at first need IT message is described:
With mobile soft switchcall server is example, when the user enters talking state, can set up one between MSC server and the BSC and be connected with this user-dependent signaling, the Signalling exchange between this moment MSC server and the BSC has only this signaling connection status to detect, and it is two-way that the signaling connection status detects:
The detection that the MSC server is initiated: the MSC server periodically sends out connection status detect-message (IT message) for BSC, and start a timer, before timer expiry, receive the connection status detect-message (IT message) of BSC, then think and detect successfully, and stop timer.If timer expiry then detects failure.After continuous failure N time, the MSC server enters signaling and connects Interrupt Process, discharges the calling with this join dependency.N is for can join numerical value, and minimum can be once.
The detection that BSC initiates: BSC periodically sends out connection status detect-message (IT message) for the MSC server, and start a timer, before timer expiry, receive the connection status detect-message (IT message) of MSC, then think and detect successfully, and stop timer.If timer expiry then detects failure.After continuous failure N time, BSC enters signaling and connects Interrupt Process, discharges the calling with this join dependency.N is for can join numerical value, and minimum can be once.
Signaling described in the above-mentioned flow process connects Interrupt Process and is meant, after IT message detection failure several times between MSC server and the BSC, then can disconnect data link with the opposite end, discharge the calling on this data link, for example BSC transmission IT message detection is failed after N time, confirm that then the communication between current BSC and the MSC server goes wrong (for example may cause because of the MSC server failure), then disconnect and the MSC server between data link, and discharge calling (be terminated call, and discharge the bearing resource that this calling originally took) on this data link.
In the present embodiment, BSC sends an IT message in order to detect signaling status to the MSC server, and this message need be forwarded to the MSC server by MGW, and then MGW receives the IT message that BSC sends.
202, judge whether the chain of command network element breaks down, if then execution in step 204, if not, then execution in step 203;
MGW is after an IT message that receives the BSC transmission, can determine the MSC server that an IT message should be sent to according to the target routing iinformation that is comprised in the IT message, then MGW judges whether this MSC server breaks down, concrete judgment mode can for:
(1), set up the testing mechanism of shaking hands between MSC server and the MGW, when shaking hands failure between MGW and the MSC server, then the MSC server is set is the signaling inaccessible state to MGW, and promptly definite MSC server breaks down;
(2), MGW receives Operation and Maintenance (OM, Operation and Maintenance) message of system's transmission includes an indication information in this message, and MGW judges this indication information, and whether instruct MS C server breaks down, if determine that then the MSC server breaks down;
Need to prove that the current state of MSC server can be known in the OM system, so it can send the message of instruct MS C server current state to MGW, concrete OM system knows that the process of MSC server current state is a prior art, does not do qualification herein.
(3), adopt statistical probability to judge: in normal business procedure, have interacting message between MSC server and the MGW, MGW can judge and the MSC server between continuously the failure number whether reach the thresholding that presets, be that N bar message is failed continuously, if, determine that then the MSC server breaks down, the numerical value of concrete N for disposing.
203, transmit an IT message to the chain of command network element, and finish the present embodiment flow process;
Server does not break down if MGW judges MSC, and then MGW the one IT forwards that will receive from BSC is carried out follow-up handling process to the MSC server by the MSC server.
204, generate the 2nd corresponding IT message according to an IT message;
If MGW judges the MSC server and breaks down, then MGW generates the 2nd IT message according to Local Reference Number field parameter in the IT message and Destination Reference Number field parameter, promptly generate the 2nd IT message by MGW simulation MSC, specifically MSC is consistent according to the process that Local Reference Number field parameter and Destination Reference Number field parameter generate the 2nd IT message in the process that generates the 2nd IT message by Local Reference Number field parameter and Destination Reference Number field parameter and the prior art, repeats no more herein.
Need to prove, in present embodiment and subsequent embodiment, the 2nd IT message can receiveing the response for an IT message, in addition owing to can periodically sending out IT message mutually between MSC server and the BSC in actual applications, and replace MSC server by MGW this moment, so the 2nd IT message can also initiatively be issued the IT message of BSC for MGW.
205, send the 2nd IT message to access network element.
In the present embodiment, MGW is a controlled process to the process that BSC sends the 2nd IT message, i.e. controllability and reliability in order to guarantee transfer of data, after the MSC server breaks down, in general user face data should not disconnect always, thus MGW to BSC send the 2nd IT message process can for:
(1), is found to MSC server signaling when unreachable as MGW, start a timer, before this timer expiry, MGW simulated failure MSC server is sent out the 2nd IT message to BSC, behind timer expiry, MGW no longer simulates the MSC server and sends out the 2nd IT message to BSC;
This timer can be provided with a threshold value that presets, and the size of threshold value is determined by practical application, does not do qualification herein.
(2), MGW sends the 2nd IT message and is controlled by switch, when switch opens, MGW simulated failure MSC server is sent out the 2nd IT message to BSC, when switch cuts out, MGW no longer simulates the MSC server and sends out the 2nd IT message to BSC, this switch is by the control of OM system, and the O﹠M personnel can place the state of opening or closing to switch as required;
Need to prove that this switch is a parameter, indicate whether in this parameter to allow to send, send if allow, then MGW simulated failure MSC server is sent out the 2nd IT message to BSC, if do not allow to send, then MGW no longer simulated failure MSC server send out the 2nd IT message to BSC.
Above-mentioned MGW, user's veil unit and the core network element (for example this core network element is the PSTN network element) that links to each other with the MSC server also need after satisfying release conditions, discharge and this MSC server between the resource that takies with conserve network resources, need to prove, before discharging resource, also need to determine that the MSC server breaks down, concrete basis for estimation can for:
(1), access network element or core network element and MSC server and between set up the testing mechanism of shaking hands, when shaking hands failure, then access network element or core network element, it is the signaling inaccessible state that the MSC server is set, and determines that promptly the MSC server breaks down;
(2) access network element or core network element receive the message that the OM system sends;
Judge whether described message indicates described MSC server to break down, if determine that then described MSC server breaks down;
Need to prove, the current state of MSC server can be known in the OM system, so it can be to the message of access network element or core network element transmission instruct MS C server current state, concrete OM system knows that the process of MSC server current state is a prior art, does not do qualification herein.
(3) adopt statistical probability to judge: in normal business procedure, have interacting message between access network element or core network element and the MSC server, access network element or core network element can judge and the MSC server between continuously the failure number whether reach the thresholding that presets, be that N bar message is failed continuously, if, determine that then the MSC server breaks down, the numerical value of concrete N for disposing.
After having determined that the MSC server breaks down, the condition of concrete release resource can for:
(1), works as MGW, user's veil unit or PSTN NE Discovery are to MSC server signaling when unreachable, start a timer, before this timer expiry, MGW, user's veil unit or PSTN network element do not discharge and fault MSC server between the resource that takies, behind timer expiry, discharge and fault MSC server between the resource that takies.
This resource is meant when calling out that the user who sets up between MGW or user's veil unit or PSTN network element and the MSC server is carried the resource of this calling, after timer expiry, then need turn-off data to connect, and call release, i.e. terminated call flow process, and discharge the resource that this calling takies.
Call out after occupied resource discharges when this, this part resource promptly becomes available resources, can be used by other business, therefore when timer expiry after, discharges the resource that this calling takies and can make that resource is repeated to utilize, the raising resource utilization.
(2), control by switch: when switch opens, MGW, user's veil unit or PSTN network element do not discharge and fault MSC server between the resource that takies, when switch cuts out, MGW, the resource that takies between user's veil unit or release of PSTN network element and the fault MSC server, switch is controlled by OM, the O﹠M personnel can place the opening and closing state to switch as required, and in fact this switch and aforesaid Switch can be parameters that is used to indicate whether to discharge resource seemingly.
Need to prove, if the signaling between MSC server and the PSTN network element is by Signalling Transfer Point (STP, Signaling Transfer Point) transmits, then when the MSC server breaks down, the STP unreachable information of signalling point state that overseas broadcast immediately is not relevant with fault MSC server, but will satisfy the broadcast conditional that presets by the time the time, just can send the unreachable information of this signalling point state, concrete judge satisfy broadcast conditional mode can for:
(1), timer mode: when judging that the chain of command network element breaks down, STP starts timer, judges whether described timer reaches to preset thresholding, if reach, then determines the satisfied broadcast conditional that presets;
(2), on-off mode: when switch opens, STP is the unreachable information of broadcast signaling dotted state not, when switch cuts out, STP just understands the unreachable information of broadcast signaling dotted state, switch is controlled by OM, the O﹠M personnel can place the opening and closing state to switch as required, and in fact this switch and aforesaid Switch seemingly can be one and be used to indicate whether the parameter broadcasted.
Need to prove, in the prior art, when the MSC server breaks down, if adopt STP, then STP can determine at first that broadcasting area is all network elements that link to each other with this STP, in this scope, broadcast the unreachable information of MSC server signalling point state afterwards, these network elements are after the unreachable information of signalling point state of receiving STP broadcasting, then can disconnect with the MSC server between be connected, so can interrupt the signaling plane data, thereby interruption user face data, but in the present embodiment, when the MSC server breaks down, STP can not broadcast this information immediately, therefore make the network element that links to each other with STP can not disconnect immediately with fault MSC server between be connected, thereby can be so that break down at the chain of command network element, under the situation of signaling plane data interruption, the business datum of other types still can be kept, so can improve user experience.
In the above-mentioned flow process, because BSC can receive the IT message that MGW simulation MSC server sends from MGW, so BSC thinks that this connection is normal, do not do abnormality processing, user's conversation can continue to keep, and therefore can improve user experience.
Two, by the resource that takies between access network element delay release and the chain of command network element:
In the present embodiment, when BSC perceives the MSC server when breaking down, BSC do not discharge immediately with this MSC server between the resource that takies, just discharge this resource afterwards but satisfy the release conditions that presets, thereby can keep the user side data communication.
Specifically see also Fig. 3, method for holding business second embodiment comprises in the embodiment of the invention:
301, transmission data;
In the present embodiment, the data between BSC transmission mobile subscriber and the fixed-line subscriber comprise signaling plane data and user face data, and concrete transmission course is not done qualification herein.
302, judge whether the chain of command network element breaks down, if then execution in step 303, if not, then execution in step 301;
BSC judges whether the MSC server breaks down, if do not break down, then continues the transmission data, if break down, then execution in step 303, the concrete process of judging can for:
(1), set up the testing mechanism of shaking hands between MSC server and the BSC, when shaking hands failure between BSC and the MSC server, then the MSC server is set is the signaling inaccessible state to BSC, and promptly definite MSC server breaks down;
(2), BSC receives the message that the OM system sends, and includes an indication information in this message, BSC judges this indication information, and whether instruct MS C server breaks down, if determine that then the MSC server breaks down;
Need to prove that the current state of MSC server can be known in the OM system, so it can send the message of instruct MS C server current state to BSC, concrete OM system knows that the process of MSC server current state is a prior art, does not do qualification herein.
(3), adopt statistical probability to judge: in normal business procedure, have interacting message between MSC server and the BSC, BSC can judge and the MSC server between continuously the failure number whether reach the thresholding that presets, be that N bar message is failed continuously, if, determine that then the MSC server breaks down, the numerical value of concrete N for disposing.
303, judge whether to satisfy the release conditions that presets, if then execution in step 305, if not, then execution in step 304;
When BSC judges that the MSC server breaks down, then judge the current release conditions that presets that whether satisfies, if satisfy, then execution in step 305, if do not satisfy, then execution in step 304.
Concrete deterministic process can for:
(1), when BSC is found to MSC server signaling when unreachable, start a timer, before this timer expiry, do not discharge the resource with fault MSC server, behind timer expiry, discharge resource with fault MSC server.
Need to prove that if before timer expiry, BSC is found to MSC server signalling point and can have reached again, then stops this timer.
(2), control by switch, when switch opens, do not discharge resource with fault MSC server, when cutting out, switch discharges resource with fault MSC server, switch is controlled by OM, the O﹠M personnel can place the opening and closing state to switch as required, and this switch can be a parameter, be used to indicate BSC whether to discharge and the MSC server between the resource that takies.
304, the resource that takies between reservation and the chain of command network element, and repeated execution of steps 303;
If BSC judges the current above-mentioned release conditions that presets that do not satisfy, then keep and this MSC server between the resource that takies, then can be so that customer service temporarily is not interrupted.
Need to prove, in the BSC reservation of resource, also need to continue detection and whether satisfy the release conditions that presets.
305, the resource that takies between release and this chain of command network element.
If BSC judges the current above-mentioned release conditions that presets that satisfies, the then resource that takies between release and this MSC server, and process ends.
Need to prove that in the present embodiment, user's veil unit and core network element can postpone to discharge resource equally, the mode among concrete delayed mode and aforementioned first embodiment is similar;
In the present embodiment, if adopt the mode of STP to transmit data between chain of command network element and the core network element, then STP can postpone the unreachable information of broadcast signaling dotted state equally, and the mode among concrete mode and aforementioned first embodiment is similar.
In the present embodiment, BSC after knowing that the MSC server breaks down, can't discharge immediately and this MSC server between the resource that takies, so can temporarily keep customer service, i.e. user's conversation can continue to keep, and therefore can improve user experience.
