Description

A kind of method of call treatment, equipment and mobility management entity

Technical field

The present invention relates to wireless communication field more particularly to a kind of method of the call treatment based on circuit domain, equipment and Mobility management entity.

Background technique

Growth and LTE(Long Term Evolution with wireless data service demand, long term evolution) flattening net The maturation of network system commercialization condition, operator is in existing GERAN/UTRAN(GSM EDGE Radio Access Network/ UMTS Territorial Radio Access Network, GSM EDGE Radio Access Network/UMTS Terrestrial radio access network) On the basis of network, meet the wireless data service demand of people's rapid growth by LTE network is gradually introducing, but how For user voice traffic services are provided while introducing LTE network, become that operator's introducing LTE network has to face asks Topic.

Based on CSFB(Circuit Switched Fallback, circuit domain voice fallback) voice service of technology is one Kind is not introducing IMS(IP Multimedia Subsystem IP multimedia subsystem) in the case where, utilization is existing The scheme of GERAN/UTRAN network implementations voice communication.The program is when user terminal initiates voice service, by EPS (Evolved Packet System, evolution packet grouping system) network indicating user terminal fall back to objective circuit domain network it Afterwards, audio call is initiated.

Specifically, CS Fallback is to realize voice fallback, i.e. MME by reusing the method for Gs interface (Mobility Management Entity, mobility management entity) and MSC(Mobile Switching Center, it is mobile Switching centre) between there are a SGs interface, the function and SGSN(Serving GPRS Support Node of the SGs interface, Serving GPRS Support Node) and MSC between Gs interface function it is similar.

When user terminal is calling terminal, calling terminal is after initiating caller voice service, the MME of calling terminal attachment Indicate that the eNodeB that is currently accessed of calling terminal service falls calling terminal into objective circuit domain network after rise, the eNodeB according to The ability of calling terminal falls calling terminal into objective circuit domain network after rise, is sent out in the network of objective circuit domain by calling terminal Play caller voice service.

But when user terminal is called terminal, there are called services by the MME that MSC notifies terminal to adhere to, and by terminal The eNodeB that the MME instruction terminal service of attachment is currently accessed falls terminal into objective circuit domain network after rise, the eNodeB root Terminal is fallen after rise into objective circuit domain network according to the ability of terminal, establishes circuit domain company in the network of objective circuit domain by terminal It connects, completes the voice calling service with calling terminal.

Terminal fall after rise to objective circuit domain network this during, terminal attachment MME not only send response message to MSC, but also transmitting line domain dropping message waits the response message of the circuit domain dropping message of terminal, works as terminal to terminal Entering signal blind area, can not reflex circuit domain dropping message in time response message to MME when, or when terminal is in reflex circuit Before the response message of domain dropping message is to MME, the eNodeB of terminal access is not due to having data transmission release between terminal S1 is linked so that UE is in idle condition, and MME could not receive the response message of the circuit domain dropping message of terminal replies, cause It is constantly in wait state, and causes call failure；Meanwhile MSC, after the response message for receiving MME transmission, forward is extremely Iu/A interface waits the response of terminal, when terminal occurs abnormal, can not obtain the exception information in time, be constantly in forward shape State cannot initiate new voice service in time, cause the success rate of audio call low.

Specific embodiment

For the purposes of the present invention, the embodiment of the invention provides a kind of method of call treatment, equipment and mobility pipes Entity is managed, it is additional to increase once to the paging operation of terminal when the CS paging described in the non-normal response of the terminal notifies, It can be improved terminal voice call success rate.

The each embodiment of the present invention is described in detail with reference to the accompanying drawings of the specification.

Embodiment one:

As shown in Figure 1, the flow diagram of the method for a kind of call treatment of the embodiment of the present invention one, the method packet It includes:

Step 101: mobile management entity MME receives the terminal that is used to indicate that moving exchanging center MSC is sent and falls back to electricity First CS paging in road domain is requested.

When MSC receives the voice call request for carrying terminal iidentification, the corresponding terminal of the terminal iidentification is determined For attachment (Attached) state, and determine by existing SGs interface the MME of the terminal attachment.

The MSC sends to be used to indicate the terminal and fall back to the first CS paging of circuit domain to determining MME and ask It asks.

For example, first CS paging request can be CS Paging Request message.

Step 102: the MME determines that the terminal is in connected state, is requested according to first CS paging, described MME is to terminal transmitting line domain page notification.

The MME can inquire the state of the terminal when receiving the request of the first CS paging, be tied according to inquiry Fruit determines that the terminal is in connected state.

For example, the MME inquires presently described terminal according to the terminal iidentification for including in first CS paging request Identify the status information of the corresponding terminal；

When the status information for inquiring the terminal is in connection status, determine that the terminal is currently at connection shape State；

When the status information for inquiring the terminal is to be in idle condition, determine that the terminal is currently at idle shape State.

The MME can be sent out on existing signaling link to the terminal when determining that the terminal is in connected state Circuit domain page notification (CS Paging Notification) is sent, circuit domain business notice (CS Service is also possible to Notification).

Meanwhile the MME can send call answering message to the MSC, and the MSC is notified to lead to CS paging Know that message is sent to the terminal, is waiting the page-response message of terminal.

For example, the call answering message can be service request (Service Request) message.

The MSC, can be described in forward to Iu/A interface waiting when receiving the call answering message that the MME is sent The call of terminal.

Step 103: the MME determines that CS paging described in the non-normal response of the terminal notifies.

The MME determines that the mode of the notice of CS paging described in the non-normal response of the terminal includes but is not limited to following Mode:

First way:

For example, the MME can star first timer to after the page notification of terminal transmitting line domain, it is described MME judges that whether receiving the terminal in first timer timing arrival setting this time interval of the first duration returns The CS paging push-notification-answer message returned.

Since the first duration of the setting can refer to the timing opening first timer, and timing numerical value reaches setting numerical value This duration terminated.

The first duration of the setting can be set to 8 seconds, can also be set as needed as other times length, here Without limitation.

The MME to after the page notification of terminal transmitting line domain, in etc. described in the terminal to be received returns The state of CS paging push-notification-answer message.

Due to being requested in the MME according to first CS paging, Xiang Suoshu terminal transmitting line domain page notification During this signalling, the connection status of terminal can change at any time, i.e., be converted by normal connection status For connection abnormality (such as: the terminal enters the blind area of communication network, can not communicate etc. between MME), or Connection idle state is converted into (between the i.e. described terminal and the evolution base station eNodeB being currently accessed by normal connection status There is no data transmission etc.) so that the MME will persistently wait the terminal to return to the CS paging push-notification-answer message, The MME is caused to wait the CS paging push-notification-answer message time-out, therefore, the MME is logical in the paging of transmitting line domain Know to after the terminal, OnNow first timer, monitoring the first timer timing reach the first duration of setting this The CS paging push-notification-answer message that the terminal returns whether is received in one time interval, determines the end in real time The connection status of end in a communication network.

The second way:

The MME receives institute according to the MME within the first time period after sending the CS paging and notifying The connection context release request for stating the terminal of eNodeB transmission, determines that circuit domain described in the non-normal response of the terminal is sought It calls through and knows.

Wherein, the connection context release request of the terminal can be terminal contexts release request (UE Context Release Request) message.

The MME starts first timer to after the page notification of terminal transmitting line domain, and the MME judges The first timer timing reaches the institute that the eNodeB is sent whether is received in setting this time interval of the first duration State the connection context release request of terminal.

Since the first duration of the setting refer to the timing opening first timer, and timing numerical value, which reaches setting numerical value, to be terminated This duration.

Described in being received in first timer timing arrival setting this time interval of the first duration as the MME The connection context release request for the terminal that eNodeB is sent, determines CS paging described in the non-normal response of the terminal Notice.

It should be noted that the terminal to be received such as setting MME responds the circuit domain and seeks when starting first timer The time known is called through, such as: Start T1_MME, CS Paging Notification=the first duration=8S；It can also be arranged When the first timer timing reaches first duration, the operation of execution is jumped, such as: in the first timer meter When reaching first duration, triggering executes step 104(Trigger104When expires).

It can be seen that the MME send within the first time period after CS paging notice occur with down toward When a kind of few situation, determine that CS paging described in the non-normal response of the terminal notifies:

The terminal is not received after sending the first time period after the CS paging notice to seek the circuit domain Call through the response message known；

The eNodeB transmission is received sending the MME within the first time period after the CS paging notice The terminal connection context release request.

It should be noted that the first time period can be preset, can also be by Timer Controlling, here Without limitation.

It should be noted that it can be the request (Extend that activates business that the terminal, which responds the CS paging notice, Service Request) message.

Step 104: the MME determine CS paging described in the non-normal response of the terminal notice when, by with drill Communicating into base station eNodeB by the status change of the terminal is Idle state.

Specifically, at step 104, the MME is become the state of the terminal by communicating with evolution base station eNodeB It moves and is included, but are not limited to, the following ways for the mode of Idle state:

Firstly, the MME sends the connection context release command of the terminal to the eNodeB.

For example, the connection context release command of the terminal can be terminal contexts release command (UE Context Release Command) message.

Secondly, the connection context that the MME receives the terminal that the eNodeB is sent completes message.

The eNodeB discharges the eNodeB and the end when receiving the connection context release command of the terminal S1 connection between end, and the connection context for sending the terminal completes message to the MME.

For example, the connection context of the terminal, which completes message, can complete (UE Context for terminal contexts release Release Complete) message.

The status change of the terminal is Idle state by third, the MME.

Step 105: the MME is requested according to first CS paging, and Xiang Suoshu terminal sends second circuit domain and seeks It calls for asking.

Specifically, in step 105, the MME is become the state of the terminal by communicating with evolution base station eNodeB The CS paging push-notification-answer message that the terminal returns can not be received for Idle state by moving, according to first electricity Road domain paging request initiates second circuit domain paging request to the terminal in time, additional in this way to increase primary paging, increases The success rate of audio call between terminal and terminal.

Step 106: the MME according to the terminal to the response condition of second circuit domain paging request, after execution Continuous operation.

For example, the MME is after initiating second circuit domain paging request to the terminal, when receiving within the set duration The terminal is to the response message that receives of second circuit domain paging request, and the MME is to eNodeB transmission for referring to Show the instruction message that circuit domain dropping is carried out to the terminal.

The instruction message indicates that the terminal is fallen after rise to target network, establishes circuit domain connection and completes voice communication.

For example, the response message that receives can be Extended Service Request message, the MME is in determination When the terminal response is from the calling in the domain CS, UE Radio Capabilities is contained to eNodeB transmission The Initial Context Setup Request message of parameter and CS Fallback Indicator parameter, described in instruction The terminal is fallen back to objective circuit domain network by eNodeB, and receives the Initial Context that the eNodeB is returned Setup Request message.

As it can be seen that mobility management entity is in the non-normal response CS paging notice of terminal, it is additional to increase once to end The paging operation at end can be improved terminal voice call success rate.

Disappear alternatively, the terminal ought not received within the set duration to the response of second circuit domain paging request Breath, the MME send paging failure message to moving exchanging center MSC belonging to the terminal；It can also notify the MSC, So that it is suspended forward and waits operation.

May include failure cause in the paging failure message sent to the MSC is the unreachable (UE of UE Unreachable).

As it can be seen that the MME is timely when not receiving the page-response message that the terminal returns in the duration in setting It notifies MSC belonging to the terminal, enables the MSC to suspend forward and wait operation, save Internet resources.

Alternatively, the MME receives the terminal to the refusal of second circuit domain paging request within the set duration Response message, the MME send paging failure message to MSC belonging to the terminal.It may include losing in paging failure message Losing reason is that user refuses CS calling.

For example, the message that refuses to respond can be Extended Service Request message, when the MME is received To Extended Service Request message in carry and refuse to respond instruction (such as: Paging Reject instruction).

One scheme through the embodiment of the present invention, mobility management entity MME circuit domain described in the non-normal response of terminal It is additional to increase once to the paging operation of terminal when page notification, it can be improved terminal voice call success rate.When in setting When not receiving the page-response message that the terminal returns in duration, moving exchanging center MSC is notified in time, so that described MSC suspends forward and waits operation, saves Internet resources.

Embodiment two:

As shown in Fig. 2, the flow diagram of the method for a kind of call treatment of the embodiment of the present invention two.The present invention is implemented Example is second is that detailed description to the embodiment of the present invention one, which comprises

Step 201: mobile management entity MME receives the terminal that is used to indicate that moving exchanging center MSC is sent and falls back to electricity First CS paging in road domain is requested.

When MSC receives the voice call request for carrying terminal iidentification, the corresponding terminal of the terminal iidentification is determined Attached state, and determine by existing SGs interface the MME of terminal attachment.

The MSC sends to be used to indicate the terminal and fall back to the first CS paging of circuit domain to determining MME and ask It asks, the MME is notified to there is the calling instruction for calling the corresponding terminal of the terminal iidentification.

Specifically, the first CS paging request can be calling indication message, can also be CS Paging Request message.

The MME inquires the network state that the terminal is presently in when receiving the request of the first CS paging, is to connect Connect state or idle state.

Such as: the MME receive mobile switching centre transmission contain the first CS paging of terminal iidentification When request, the status information of the corresponding terminal of presently described terminal iidentification is inquired；

When the status information for inquiring the terminal is in connection status, it is determined that the terminal is currently at connection State；

When the status information for inquiring the terminal is to be in idle condition, it is determined that the terminal is currently at the free time State.

And the MME executes following operation when inquiry determines that the terminal is currently at connection status.

Step 202: the MME determines that the terminal is in connected state, is requested according to first CS paging, described MME is to terminal transmitting line domain page notification.

In step 202, it when the MME determines that the terminal is in connected state, is asked according to first CS paging It asks, circuit domain business notice can be also possible on existing signaling link to terminal transmitting line domain page notification.

For example, the CS paging notice can be CS Paging Notification message, the circuit domain industry Business notice can be CS Service Notification message.

Step 203: the MME starts first timer to when the page notification of terminal transmitting line domain.

Step 204: the MME judges to reach in setting this time interval of the first duration in the first timer timing Whether the CS paging push-notification-answer message that the terminal return is received, if it is not, thening follow the steps 205；If so, Execute step 213.

Wherein, since the first duration of the setting can refer to the timing opening first timer, and timing numerical value, which reaches, to be set This duration that fixed number value terminates.

The MME is being returned to the terminal to be received such as after the page notification of terminal transmitting line domain, being constantly in The state of the CS paging push-notification-answer message.

Step 205: the MME is reached in setting this time interval of the first duration according in the first timer timing The CS paging push-notification-answer message that the terminal returns is not received, determines electricity described in the non-normal response of the terminal Road domain page notification.

Step 206: the MME determine CS paging described in the non-normal response of the terminal notice when, by with drill Communicating into base station eNodeB by the status change of the terminal is Idle state.

In step 206, firstly, the MME sends the connection context release command of the terminal to the eNodeB.

Wherein, the connection context of the terminal, which completes message, can complete (UE Context for terminal contexts release Release Complete) message bearing transmission.

The status change of the terminal is Idle state by third, the MME.

Step 207: the MME is requested according to first CS paging, and Xiang Suoshu terminal sends second circuit domain and seeks It calls for asking.

Specifically, in step 207, the MME is become the state of the terminal by communicating with evolution base station eNodeB The CS paging push-notification-answer message that the terminal returns can not be received for Idle state by moving, according to first electricity Road domain paging request initiates second circuit domain paging request to the terminal in time, additional in this way to increase primary paging, increases The success rate of audio call between terminal and terminal.

Step 208: the MME judges whether connect sending in the second time period after the paging request of the second circuit domain The terminal is received to the response message of second circuit domain paging request, if receiving, thens follow the steps 209~211；It is no Then, step 212 is executed.

Step 209: the MME receives the terminal to the sound of second circuit domain paging request within the set duration Message is answered, judges whether contain the finger of calling of the refusal from the domain CS in the response message of second circuit domain paging request It enables, if containing refusal instruction, thens follow the steps 210；If not thening follow the steps 211 comprising refusal instruction.

Specifically, the response message of second circuit domain paging request can be Extended Service Request Message.

The terminal is circuit domain according to the core network domain type carried in the second circuit domain paging request received, is sentenced It is disconnected whether to respond the calling from the domain CS, and the response message of second circuit domain paging request is sent to the MME.

Step 210: when the response for the second circuit domain paging request that the terminal that the MME is received is sent disappears When containing refusal instruction in breath, MME transmission refuse to respond message (such as: SGsAP-PAGING-REJECT message) to The MSC terminates the domain CS call operation.

It wherein, may include that failure cause calls for user's refusal CS in paging failure message.

For the MSC when receiving the refusal speech call information that the MME is sent, pause forward waits operation, forward The voice call service to the terminal is initiated to Iu/A interface.

Step 211: when the response for the second circuit domain paging request that the terminal that the MME is received is sent disappears When in breath not comprising refusal instruction, the MME determines the calling of the terminal response from the domain CS, and Xiang Suoshu eNodeB, which is sent, to be used The instruction message of circuit domain dropping is carried out to the terminal in instruction.

Specifically, in step 211, the MME is when determining the terminal response from the calling in the domain CS, Xiang Suoshu ENodeB transmission contains terminal wireless transmitting-receiving ability UE Radio Capabilities parameter and the domain CS voice fallback instruction CS The initial context of Fallback Indicator parameter establishes request Initial Context Setup Request message, It indicates that the terminal is fallen back to objective circuit domain network by the eNodeB, and receives the initial context that the eNodeB is returned It establishes and replys Initial Context Setup Response message.

Step 212: the MME does not receive the terminal to second circuit domain paging request within the set duration Response message, Xiang Suoshu MSC send paging failure message.

Specifically, in the step 212, the MME does not receive the terminal to the second circuit within the set duration The response message of domain paging request determines that the terminal is in abnormal connection status, this paging can not be responded, to the end Moving exchanging center MSC belonging to end sends paging failure message, can also notify the MSC, so that it is suspended forward and waits behaviour Make.

Step 213: the MME is reached in setting this time interval of the first duration according in the first timer timing The CS paging push-notification-answer message that the terminal returns is received, Xiang Suoshu eNodeB transmission is used to indicate to described The instruction message of terminal progress circuit domain dropping.

In step 213, it is used to indicate in the MME to eNodeB transmission and circuit domain dropping is carried out to the terminal Instruction message before, can also further judge that whether containing refusal in the CS paging push-notification-answer message comes from The operation of the instruction of the calling in the domain CS, subsequent execution is identical as step 209~step 212, is not described herein.

Two scheme through the embodiment of the present invention, mobility management entity MME are determining the non-normal response institute of the terminal When stating CS paging notice, Xiang Suoshu terminal sends second circuit domain paging request, additional to increase once to the paging of terminal Operation, can be improved terminal voice call success rate.It is rung when not receiving the paging that the terminal returns in the duration in setting When answering message, moving exchanging center MSC is notified in time, so that MSC pause forward waits operation, saves Internet resources.

Embodiment three:

As shown in figure 3, the flow diagram of the method for a kind of call treatment of the embodiment of the present invention three, the present invention is implemented Example is third is that invention with the embodiment of the present invention one and the embodiment of the present invention two under same design, which comprises

Step 301: mobile management entity MME receives the terminal that is used to indicate that moving exchanging center MSC is sent and falls back to electricity First CS paging in road domain is requested.

For example, the first CS paging request can be CS Paging Request message, it can also be SGs AP-PAGING-REQUEST message.

The MME inquires the state of the terminal when receiving the request of the first CS paging, according to query result, Determine that the terminal is in connected state.

For example, the MME receive mobile switching centre transmission contain the first CS paging of terminal iidentification When request, the status information of the corresponding terminal of presently described terminal iidentification is inquired；

The MME executes following operation when inquiry determines that the terminal is currently at connection status.

Step 302: the MME determines that the terminal is in connected state, is requested according to first CS paging, described MME is to terminal transmitting line domain page notification.

When the MME determines that the terminal is in connected state, requested according to first CS paging, it can be existing Signaling link on to terminal transmitting line domain page notification (CS Paging Notification), be also possible to circuit Domain service announcements (CS Service Notification).

For example, the call answering message can be service request Service Request message.

Step 303: the MME is according to the MME within the first time period after sending the CS paging and notifying The connection context release request for receiving the terminal that the eNodeB is sent, determines described in the non-normal response of the terminal CS paging notice.

Wherein, the connection context release request of the terminal can disappear for UE Context Release Request Breath.

Specifically, the MME starts first timer, and judge to after the page notification of terminal transmitting line domain Reach in setting this time interval of the first duration whether receive what the eNodeB was sent in the first timer timing The connection context release request of the terminal.

It should be noted that the length value for sending the first time period after CS paging notice can with set The calculation of the first fixed duration is identical, can also be different, here without limitation.

Step 304: the MME determine CS paging described in the non-normal response of the terminal notice when, by with drill Communicating into base station eNodeB by the status change of the terminal is Idle state.

Specifically, in step 304, the MME is become the state of the terminal by communicating with evolution base station eNodeB It moves and is included, but are not limited to, the following ways for the mode of Idle state:

For example, the connection context release command of the terminal can disappear for UE Context Release Command Breath.

Wherein, the connection context of the terminal completes message can disappear for UE Context Release Complete Breath.

The status change of the terminal is Idle state by third, the MME.

Step 305: the MME is requested according to first CS paging, and Xiang Suoshu terminal sends second circuit domain and seeks It calls for asking.

Specifically, in step 305, the MME is become the state of the terminal by communicating with evolution base station eNodeB The CS paging push-notification-answer message that the terminal returns can not be received for Idle state by moving, according to first electricity Road domain paging request initiates second circuit domain paging request to the terminal in time, additional in this way to increase primary paging, increases The success rate of audio call between terminal and terminal.

Step 306: the MME judges whether receive after sending the second time period after the paging request of the second circuit domain To the terminal to the response message of second circuit domain paging request, if so, thening follow the steps 307 or step 307/；If It is no, then follow the steps 308.

For example, the MME starts second timer, and sentence when initiating second circuit domain paging request to the terminal Break and reaches in setting this time interval of the second duration whether receive what the terminal returned in the second timer timing The response message of second circuit domain paging request thens follow the steps 307 or step 307/ if receiving；Otherwise, step is executed 308。

Since the second duration of the setting can refer to the timing opening second timer, and count value reaches setting numerical value This section of duration terminated, second duration are less than first duration.

For example, described first when is 8 seconds a length of, described second when, is 6 seconds a length of, here without limitation.

It should be noted that within step 306, the second time period sent after the paging request of the second circuit domain It can be realized, can also be realized by other means, here without limitation by second timer timing.

Specifically, within step 306, the MME to the terminal after initiating second to page, when needing to wait one section Between receive the response message (such as: Extend Service Request message) of the terminal, start second timer at this time, The MME can detect the time for the response message for receiving the terminal, avoid waiting-timeout, moreover it is possible to determine in time Whether the terminal is in abnormality.

Step 307: the MME receives the end sending in the second time period after the paging request of the second circuit domain Hold to the response message that receives of second circuit domain paging request, Xiang Suoshu eNodeB transmission be used to indicate to the terminal into The instruction message of row circuit domain dropping.

Step 307/: the MME receives the terminal to second circuit domain paging request within the set duration Message is refused to respond, the MME sends paging failure message to MSC belonging to the terminal.It can wrap in paging failure message Including failure cause is that user refuses CS calling.

Optionally, before executing step 307 or step 307/, institute can also can be further judged with the MME It states and whether contains the instruction of calling of the refusal from the domain CS in CS paging push-notification-answer message, refer to if containing refusal It enables, thens follow the steps 307/；Otherwise, step 307, step 209~step 211 in concrete mode and present example two are executed Mode is identical, is not described herein.

Step 308: the MME send do not received in the second time period after the paging request of the second circuit domain it is described Terminal to the response message of second circuit domain paging request, seek by moving exchanging center MSC transmission belonging to Xiang Suoshu terminal Exhale failed message.

In step 308, the MME is not received described when the second timer timing reaches the second duration of setting The response message for the second circuit domain paging request that terminal returns, the hair of moving exchanging center MSC belonging to Xiang Suoshu terminal Send paging failure message.

For the MSC when receiving the paging failure message that the MME is sent, pause forward waits operation, forward to Iu/ A interface initiates the voice call service to the terminal.

The MSC can also re-initiate the voice call service to the terminal.

Three scheme through the embodiment of the present invention, mobility management entity MME receive the use that moving exchanging center MSC is sent The first CS paging request of circuit domain is fallen back in instruction terminal, the MME determines that the terminal is in connected state, according to The first CS paging request, the MME determine the end to terminal transmitting line domain page notification, the MME The notice of CS paging described in non-normal response is held, the MME with evolution base station eNodeB by communicating the shape of the terminal State transition are Idle state, and the MME is requested according to first CS paging, and Xiang Suoshu terminal sends the paging of second circuit domain Request, and judge not receiving the terminal to described sending in the second time period after the paging request of the second circuit domain The response message of second circuit domain paging request, moving exchanging center MSC belonging to Xiang Suoshu terminal send paging failure message, So that the MSC pause forward waits operation；And it is sending in the second time period after the paging request of the second circuit domain The terminal is received to the response message that receives of second circuit domain paging request, Xiang Suoshu eNodeB transmission is used to indicate The instruction message of circuit domain dropping is carried out to the terminal, so that the terminal is fallen after rise to target network, realizes audio call, volume Outer increase once to the paging operation of terminal, can not only make terminal notify the MSC pause forward when occurring abnormal in time Operation is waited, Internet resources are saved；And increase the chance that a terminal is paged, improve terminal voice call at Power.
