And so on, but due to factors such as limited frequency resources of the wireless communication system and poor transmission environment, it is impossible to provide a high access rate. With the development of communication technologies, the emerging broadband wireless access technology has made up for the above shortcomings. The broadband wireless access technology represented by WLAN (Wireless Local Area Network) and WiMAX (Worldwide Interoperabiation for Microwave Access) can provide high-speed broadband wireless access services. It also supports nomadic and mobile applications, greatly improving the accessibility of wireless communications. After the network is evolved, the terminal can obtain the required service by accessing any one of the evolved network structures.

The S101 interface between the broadband radio access network and the mobility management entity is a transmission interface between different evolved networks, and the interface communicates through a tunnel protocol, through which the communication between the terminal and the target network is for the source network. It is transparent, thereby reducing the impact of handover on the source network, and minimizing the coupling between the evolved evolved networks; and the S103 interface between the broadband radio access network and the local service gateway is different from the evolved network. The interface for data forwarding is to ensure that the data sent to the source network can be correctly forwarded to the target network to ensure data loss.

The failure information may be a value of the cause of the failure or a mapping value obtained by mapping the cause value, or a first indication or a second indication sent by the network side. Referring to Figure 3, taking the failure information as a specific example, in the process of network switching, the method is as follows:

Referring to FIG. 4, the first indication or the second indication sent by the network side is specifically taken as an example. In the process of changing, the method is as follows:

D1: The mobility management entity learns that the pre-registration failure or the network handover fails, obtains the cause value that causes the failure, and sends the cause value to the base station;

In summary, the method provided by the embodiment of the present invention can ensure that the pre-registration failure or the handover failure is correctly notified in the scenario of pre-registration failure or network handover failure in the pre-registration and handover process, and the correct Control the behavior of the terminal to reduce the waste of air interface resources and the impact on the current service of the network.

In order to describe the method provided by the foregoing embodiments of the present invention in detail, refer to the following embodiments: Embodiment 1

For example, FIG. 5 is a schematic diagram of a scenario architecture provided by an embodiment of the present invention, including: a terminal UE, a base station eNB, and an MME (Mobility Management Entity). , mobility management entity) and HRPD AN (Access Net, access network). It can be known by those skilled in the art that in the process of pre-registration or handover of the terminal, the S101 interface or interface communication between the MME and the HRPD AN may cause an error, which may cause the pre-registration process initiated by the terminal to fail.

Therefore, when an error occurs in the S101 interface, in order to notify the terminal in time, thereby controlling the subsequent behavior of the terminal, to reduce the waste of the air interface resources and the impact on the current service of the LTE network, the embodiment of the present invention provides a method for failure notification, which is performed by the terminal. The pre-registration process is described as an example. Referring to Figure 6, the method is as follows:

Step 101: The terminal initiates a pre-registration process. The detailed process of the terminal initiating the pre-registration process in the step 101 may be described in detail in the LTE-to-HRPD handover provided by the prior art, which is not in the prior art.

Step 102: In the pre-registration process, the MME determines whether an error occurs in the S101 interface or the S101 interface communication; if yes, executing step 103; otherwise, performing the pre-registered stalk subsequent flow stalk in the prior art, the embodiment of the present invention No longer;

For example, in FIG. 6, the MME determines whether an error occurs on the S101 interface as an example.

In this embodiment, the mobility management entity MME and the mobility management entity of the target network transmit an S101 interface or the S101 interface communication error causes the pre-registration process to fail as an example, causing the pre-registration process to fail and further including the mobility management entity. For the reasons such as the fault, the embodiment does not limit this.

The MME determines whether the S101 message transmission error occurs, and the control mechanism of the S101 interface cannot be resolved in time, which may result in the pre-registration process being incomplete.

Step 103: The MME determines a cause value that causes a communication error of the S101 interface or the S101 interface.

Refer to Table 1, which is a schematic table of the cause values of the S101 interface error provided in this embodiment.

Table 1

Among them, as shown in Table 1. The S101 interface or S101 interface communication may be incorrect, including at least the following types:

(1) System Failure, indicating a permanent error, which is difficult to eliminate in the short term;

(2) If the transmission fails, the MME or HRPD AN sends the S101 message to the peer, and no response is received. Until the Timer times out and retransmits, if the retransmission reaches the maximum number of retransmissions, it still does not receive. If the peer end responds, the transmission fails; or when the MME and the HRPD AN are based on the Echo Request/Response, when the link detection is performed based on the Response response detection mechanism, if the Response is not detected, It is considered that the link between the MME and the ΗΚΡϋ AN is incorrect, and the transmission is considered to be failed.

(3) NO Memory Available, indicating that the peer MME or HRPD AN does not have enough memory to use;

(4) Protocol Error, necessary cell error, necessary cell loss, and optional cell error to indicate protocol error;

(5) Version Not Supported, indicating that the peer cannot recognize the version number in the request message. Those skilled in the art will appreciate that the above-described S101 interface or S101 interface communication may exhibit an error type and an example of the error type does not limit the present invention.

Step 416: The MME directly sends the cause value of the S101 interface or the S101 interface communication error to the eNB. The specific implementation may be: the MME sends the downlink SI CDMA2000 tunnel (DL (DownLink) SI CDMA2000 Timneling) to the eNB. Message, which carries the cause value of the S101 interface error. The cause value may be a cause value returned according to an error in the connection establishment process during the connection establishment process of the S101, or may be a cause value mapped by the MME according to the rule described in step 103.

Step 105: The eNB receives the cause value of the S101 interface or the S101 interface communication error sent by the MME, and determines whether the cause of the S101 interface error is a long-term error according to the received cause value. If yes, step 106 is performed; otherwise, the step is performed. 108;

The eNB determines according to the received cause value to determine a subsequent message sent to the terminal, thereby controlling the behavior of the terminal, and the judgment basis may be as follows:

According to the cause of the S101 interface error, whether it can be recovered in a short period of time can be divided into: long-term error (that is, long-term failure, which may not be recovered in a short period of time) and short-term error (recoverable in a short period), where The cause value shown in 1 is, accordingly,

Long-term errors include system errors, transmission failures, etc.

Short-term errors include insufficient memory, protocol errors, version not supported, and so on.

Step 106: The eNB determines that the received cause value of the communication error of the S101 interface or the S101 interface is a long-term error, and the eNB sends a notification message to the terminal, where the notification message carries the pre-registration indication.

The pre-registration indication included in the notification message that is sent by the eNB to the terminal that does not allow the pre-registration indication is used to indicate that the terminal does not initiate the pre-registration process, and instead performs non-optimization handover. Optionally, the indication that can be carried in the notification message is to give up the re-initiation of the pre-registration, and is used to instruct the terminal to re-initiate the pre-registration, which is not limited in this embodiment. The specific implementation of the notification message may be implemented by using a downlink radio resource control protocol connection reconfiguration (ie, RRC (Radio Resource Control) Connection Reconfiguration message) that does not allow pre-registration indication to the terminal.

Step 107: The terminal receives the notification message sent by the eNB, and determines that the pre-registration process fails according to the pre-registration indication that is not carried in the notification message, and may initiate a process of performing a non-optimized handover.

Step 108: The eNB determines that the received cause value of the communication error of the S101 interface or the S101 interface indicates a short-term error, and the eNB sends a notification message to the terminal, where the notification message carries a failure indication.

And the eNB sends a notification message carrying the failure indication to the terminal, where the failure indication is used to notify the terminal that the pre-registration process fails. Wherein, when the notification message is specifically implemented, downlink information may be used to transmit DL Information. The Transfer message is implemented, and the DL Information Transfer message carries the above failure indication Failure Indicatiori.

Step 109: The terminal receives the notification message sent by the eNB, and determines that the pre-registration fails according to the failure indication Failure Indication carried in the notification message, and re-initiates the pre-registration stalk according to the local policy.

The local policy applied by the terminal may be: the terminal determines a Timer whose duration is continuously extended, and if the Timer expires, initiates a pre-registration process until the specified maximum number of re-initiation registrations is reached, thereby stopping the pre-registration process. The subsequent terminal can perform a non-optimized handover.

In addition, when the terminal determines that the pre-registration fails, the pre-registration process may also be abandoned according to the local policy. This embodiment does not impose any restrictions on the formulation of the local policy.

In addition, the failure indication sent by the network side may also be used to indicate that the terminal relinquishes the re-initiation of the pre-registration process or the re-initiation of the network handover procedure;

After the terminal receives the failure indication, if the terminal performs the pre-registration process, the terminal relinquishes the re-initiation registration process according to the received failure indication. After the terminal abandons the re-initiation of the pre-registration process, optionally, the terminal may not perform the process. The action is re-initiated. After a period of time, the terminal is disconnected from the link on the network side, which can reduce the waste of air interface resources and the impact on the current service of the LTE network.

If the terminal performs the network switching process, the terminal relinquishes the network switching process according to the received failure indication.

Through the foregoing steps 101 to 109, the method provided by the embodiment of the present invention is used as an example for the terminal to initiate the pre-registration process. The method provided by the embodiment of the present invention can ensure that the S101 occurs during the LTE and HRPD handover process. The interface or the S101 interface communicates incorrectly, correctly notifies the terminal of the switchover failure, and correctly controls the behavior of the terminal to reduce the waste of the air interface resources and the impact on the current service of the LTE network. For details, refer to the information exchange diagram provided in Figure 7: 1. UE Initiating a pre-registration process; 2. The MME determines whether the S101 interface or the S101 interface is in communication error; 3. The MME sends a cause value of the error to the eNB through the downlink S1 CDMA2000 tunnel message; 4. The eNB determines the cause of the error according to the cause value. If the error is a long-term error, the eNB sends an RRC connection reconfiguration to the UE. 6. If the error is a short-term error, the eNB sends a downlink information transmission message to the UE. Those skilled in the art will appreciate that the specific steps in steps 101 through 109 above may be combined or broken down into the steps of information interaction and processing described in FIG.

In summary, the method provided by the embodiment of the present invention, after the MME causes the cause value of the S101 interface or the S101 interface communication error to be sent to the eNB, the eNB determines a long-term error or a short-term error according to the received cause value, according to the determined error. If the type is different, a different notification message is sent to the terminal, so that if the S101 interface error occurs, the correct notification terminal fails to register in advance or the handover fails, and the behavior of the terminal is correctly controlled to reduce the waste of the air interface resources and the current service for the LTE network. Impact. Example 2

The scenario structure diagram provided in FIG. 5 is taken as an example for description. The difference from the first embodiment is that, after determining the cause value of the S101 interface or the S101 interface communication error, the MME determines the cause value directly. The mapping of the long-term and short-term errors, and then the mapping value is sent to the eNB, so that the eNB can directly send different notification messages to the terminal according to the received information, which greatly reduces the workload and working pressure of the eNB. The method is described in detail, please refer to Figure 8, which reads as follows:

Step 201: The terminal initiates a pre-registration process.

The detailed process of the terminal initiating the pre-registration process in the step 201 may be described in detail in the LTE-to-HRPD handover provided by the prior art, which is not in the prior art.

Step 202: In the pre-registration process, the MME determines whether an error occurs in the S101 interface or the S101 interface communication; if yes, step 203 is performed; otherwise, the subsequent process of the pre-registration process is performed.

For example, in FIG. 8, the MME determines whether an error occurs on the S101 interface as an example.

In this embodiment, the description that the communication failure between the mobility management entity MME and the mobility interface S101 or S101 of the mobility management entity of the target network causes the pre-registration process to fail, and the pre-registration process fails, further includes the mobility management entity. For the reasons such as the fault, the embodiment does not limit this.

Step 203: After the MME determines that an error occurs in the S101 interface or the S101 interface communication, the MME determines a cause value that causes the S101 interface or the S101 interface communication error.

As shown in Table 1, the schematic table for causing the communication error of the S101 interface or the S101 interface is provided in this embodiment. The S101 interface or S101 interface communication error includes system error, transmission failure, insufficient memory, protocol error, and version not supported.

Step 204: The MME maps the determined cause value according to the long-term and short-term error mapping relationship to obtain a mapped value. The long-term and short-term error mapping relationship includes: whether the recovery may be performed in a short period according to the cause of the communication error of the S101 interface or the S101 interface, and may be classified into a long-term error and a short-term error, where the cause value shown in Table 1 above is , Correspondingly,

Long-term errors: such as system errors, transmission failures, etc.

Short-term errors: such as insufficient memory, protocol errors, version not supported, etc.

For example, it is assumed that the cause value of the S101 interface or the S101 interface communication error determined by the MME in step 203 is represented as a system error, and in step 204, the MME maps the determined cause value to obtain a long-term error mapping. Value.

Step 205: The MME sends the obtained mapping value to the eNB.

When the step is specifically implemented, the MME may send a downlink S 1 CDMA2000 tunnel (DL S 1 CDMA2000 Tunneling) message to the eNB, where the message carries the mapping value generated by the MME.

Step 206: The eNB determines, according to the received mapping value, whether the cause of the S101 interface error is a long-term error. If yes, step 207 is performed; otherwise, step 209 is performed.

Step 207: The eNB sends a notification message to the terminal, where the notification message carries the pre-registration indication.

If the mapping value received by the eNB indicates that the error is a long-term error, the notification message carrying the pre-registration indication is not sent to the terminal, where the pre-registration indication is not allowed to be used to indicate that the terminal does not initiate the pre-registration process. Perform a non-optimized switch. Optionally, the disallowing pre-registration indication may also be used to instruct the terminal to abandon re-initiation of the pre-registration process. When the notification message is specifically implemented, the downlink RRC Connection Reconfiguration message carrying the indication that the pre-registration is not allowed may be implemented.

Step 208: The terminal receives the notification message sent by the eNB, and initiates a process of performing a non-optimized handover according to the pre-registration indication carried in the notification message.

Step 209: The eNB sends a notification message to the terminal, where the notification message carries a failure indication.

If the mapping value received by the eNB indicates that the error is a short-term error, the terminal sends a notification message carrying the failure indication, where the failure indication is used to notify the terminal that the pre-registration process fails. When the notification message is specifically implemented, the downlink information transmission DL Information Transfer message may be used, where the DL Information Transfer message carries the foregoing failure indication Failure Indication

Step 210: The terminal receives the notification message sent by the eNB, according to the failure indication carried in the notification message.

Indication, if it is determined that the pre-registration fails, the pre-registration process is re-initiated according to the local policy.

The local policy applied by the terminal may be: the terminal determines a timer that is continuously extended, and if the timer expires, initiates a pre-registration process until the specified maximum number of re-initiation registrations is reached.

Through the foregoing steps 201 to 210, the method provided by the embodiment of the present invention is used as an example for the terminal to initiate the pre-registration process. The method provided by the embodiment of the present invention can ensure that the S101 occurs during the LTE and HRPD handover process. The interface or the S101 interface communicates incorrectly, correctly notifies the terminal of the switchover failure, and correctly controls the behavior of the terminal to reduce the waste of the air interface resources and the impact on the current service of the LTE network. For details, refer to the information exchange diagram provided in Figure 9: 1. UE Initiating a pre-registration process; 2. The MME determines whether the S101 interface or the S101 interface communication error, and determines the cause value of the error; 3. The long-term and short-term error mapping of the cause value to obtain a mapping value; 4. Passing the S1CDMA2000 tunnel The message is sent to the eNB to send the mapping value; 5. The eNB determines the mapping value; 6. If the mapping value indicates that the error is a long-term error, the eNB sends an RRC connection reconfiguration to the UE; 7. If the mapping value If the error is a short-term error, the eNB sends a downlink information transmission message carrying the failure indication to the UE.

In summary, in the method provided by the embodiment of the present invention, the MME maps the cause value of the S101 interface error to the eNB, and the eNB sends a different notification message to the terminal according to the received mapping value. If the S101 interface is faulty, it can correctly notify the terminal that the pre-registration fails or the handover fails, and correctly controls the behavior of the terminal to reduce the waste of air interface resources and the impact on the current service of the LTE network. In summary, both Embodiment 1 and Embodiment 2 are solutions for performing control by the network side. Unlike Embodiment 1 and Embodiment 2, in order to reduce the working pressure and workload on the network side, the following Embodiment 3 and implementation Example 4 is a solution for performing control by the terminal side. Example 3

The scenario architecture diagram provided in Figure 5 is taken as an example for illustration. The embodiment of the present invention provides a method for failure notification. The difference from the foregoing embodiment 1 is that the terminal directly receives the cause value of the S101 interface error sent by the MME through the eNB, and the terminal performs the local policy according to the local policy. For the subsequent operations, this embodiment is still described by taking the pre-registration process of the terminal as an example. Referring to FIG. 10, the method is as follows:

Step 301: The terminal initiates a pre-registration process.

Step 302: In the pre-registration process, the MME determines whether an error occurs in the S101 interface or the S101 interface communication; if yes, executing step 303; otherwise, performing the subsequent process of the pre-registration process in the prior art, the embodiment of the present invention is no longer Narrative

In FIG. 10, an example in which the MME determines whether an error occurs on the S101 interface is taken as an example.

The MME determines whether the communication of the S101 interface or the S101 interface is incorrect. The control mechanism of the S101 interface cannot be resolved in time, and the pre-registration process cannot be completed. In this embodiment, the description of the failure of the pre-registration process by the error of the transmission interface S101 of the mobility management entity MME and the mobility management entity of the target network causes the failure of the pre-registration process to include the failure of the mobility management entity. This embodiment does not limit this.

Step 303: The MME determines a cause value that causes an S101 interface error.

For details, refer to Table 1. The causes of communication errors on the S101 interface or S101 interface include: system error, transmission failure, insufficient memory, protocol error, version not supported, etc. The cause of the error has a corresponding cause value.

Step 314: The MME directly sends the cause value of the S101 interface or the S101 interface communication error to the eNB. The specific implementation of the step may be: the MME sends the downlink SI CDMA2000 tunnel to the eNB (DL (DownLink) SI CDMA2000 Tunnel ing) message, which carries the cause value of the communication error of the S101 interface or S101 interface.

Step 305: The eNB receives the cause value of the communication error caused by the S101 interface or the S101 interface sent by the MME, and forwards the received cause value to the terminal.

The specific implementation of the step may be: the eNB receives the cause value of the communication error caused by the S101 interface or the S101 interface sent by the MME by using the downlink S1 CDMA2000 tunnel message, and then forwards the received cause value to the terminal through the DL Information Transfer. .

Step 306: The terminal receives the cause value of the S101 interface or the S101 interface communication error sent by the eNB, and determines whether the communication error of the S101 interface or the S101 interface is a long-term error according to the received cause value. If yes, step 307 is performed; otherwise, Go to step 308;

Among them, depending on whether the communication error of S101 interface or S101 interface is available, whether it can be recovered in a short period of time, it can be divided into: long-term error (that is, long-term failure, which may not be recovered in a short period of time) and short-term error (recoverable in a short period) , wherein, for the cause value shown in Table 1 above, correspondingly,

Long-term errors include system errors, transmission failures, etc.

Step 307: The terminal initiates a process of performing a non-optimized handover when the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error.

If the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error, the pre-registration is not re-triggered, and the process of performing the non-optimized handover may be initiated. Optionally, after the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error, the re-initiation of the pre-registration process is abandoned. Alternatively, the terminal may not perform the process of non-optimized handover, but does not perform any action. After a period of time, the terminal is disconnected from the link on the network side, so that the waste of air interface resources and the impact on the current service of the LTE network can be reduced.

Step 308: The terminal determines that the communication error of the S101 interface or the S101 interface is a short-term error, and then re-initiates the pre-registration process according to the local policy.

In addition, after the terminal learns that the S101 interface or the S101 interface communication error is a short-term error, it is determined that the pre-registration fails, and the pre-registration process may also be abandoned according to the local policy. This embodiment does not impose any restrictions on the local policy.

Through the foregoing steps 301 to 308, the method provided by the embodiment of the present invention is used as an example for the terminal to initiate the pre-registration process. The method provided by the embodiment of the present invention can ensure that the S101 occurs during the LTE and HRPD handover process. The interface or the S101 interface communicates incorrectly, correctly notifies the terminal that the handover fails, and correctly controls the behavior of the terminal. To reduce the waste of air interface resources and the impact on the current services of the LTE network, see the information exchange diagram provided in Figure 11: 1. The UE initiates a pre-registration process (or handover procedure); 2. The MME determines whether the S101 interface or the S101 interface is in communication error. 3. The MME sends a cause value of the error to the eNB by using the downlink S1 CDMA2000 tunnel message; 4. The eNB sends a downlink information transmission message carrying the cause value to the UE, so that the terminal performs the subsequent steps according to the received cause value and the local policy. . Those skilled in the art may know that the specific steps in the foregoing steps 301 to 308 may be combined or decomposed into the information interaction and processing steps described in FIG. In summary, the method provided by the embodiment of the present invention, after the MME causes the cause value of the S101 interface or the S101 interface communication error to be sent to the eNB, the eNB determines a long-term error or a short-term error according to the received cause value, according to the determined error. Different types of different notification messages are sent to the terminal, so that when the S101 interface or the S101 interface communication error occurs, the correct notification terminal fails to register in advance or the handover fails, and the behavior of the terminal is correctly controlled to reduce the waste of the air interface resources. And the impact on the current business of the LTE network. In the above-mentioned Embodiment 3, the network side directly sends a cause of the communication error of the S101 interface or the S101 interface to the terminal, and further, the network may further directly map the long-term and short-term errors to the determined cause value. The mapping value is sent to the terminal, and the terminal directly performs different operation processing according to the mapping value, thereby reducing the working pressure of the terminal and improving the working efficiency of the terminal side. For details, see the following:

The scenario structure diagram provided in FIG. 5 is taken as an example for description. The difference from the embodiment 3 is that, after the MME determines the cause value of the communication error of the S101 interface or the S101 interface, the determined cause value is directly performed. The mapping of the short-term and the short-term error, and then the mapping value is sent to the terminal through the eNB, and the terminal only needs to perform corresponding operations according to the mapping value, thereby greatly reducing the workload and working pressure of the terminal side, in order to explain the method provided in this embodiment in detail. , See Figure 12, the content is as follows:

Step 401: The terminal initiates a pre-registration process.

Step 402: In the pre-registration process, the MME determines whether an error occurs in the S101 interface or the S101 interface communication; if yes, step 403 is performed; otherwise, the subsequent process of the pre-registration process is performed;

For example, in FIG. 12, the MME determines whether an error occurs on the S101 interface as an example.

In this embodiment, the communication management entity MME communicates with the transmission interface S101 or S101 of the mobility management entity of the 0-label network, and the pre-registration process fails as an example. The reason why the pre-registration process fails also includes moving. For the reason of the failure of the sexual management entity, etc., this embodiment does not limit this. Step 403: After the MME determines that an error occurs in the S101 interface or the S101 interface communication, the MME determines a cause value that causes the S101 interface error.

Step 404: The MME maps the determined cause value to obtain a mapping value according to the long-term and short-term error mapping relationship. The long-term and short-term error mapping relationship includes: whether the recovery may be performed in a short period according to the cause of the communication error of the S101 interface or the S101 interface. It can be divided into two types: long-term error and short-term error, in which, for the cause value shown in Table 1 above, correspondingly,

Long-term errors: such as system errors, transmission failures, etc.

For example, if the cause value of the S101 interface or the S101 interface communication error determined by the MME in step 403 is represented as a system error, then in step 404, the MME maps the determined cause value to obtain a long-term error mapping value.

Step 405: The MME sends the obtained mapping value to the eNB.

When the step is specifically implemented, the MME may send a downlink S 1 CDMA2000 tunnel (DL S 1 CDMA2000 Timing) message to the eNB, where the message carries the mapping value generated by the MME.

Step 406: The eNB receives the mapping value sent by the MME, and forwards the received mapping value to the terminal.

The eNB may send the mapping value to the MME through the downlink S1 CDMA2000 tunnel message, and forward the received mapping value to the terminal through the DL Information Transfer message.

Step 407: The terminal receives the mapping value sent by the eNB, and determines whether the communication error of the S101 interface or the S101 interface is a long-term error according to the received mapping value. If yes, step 408 is performed; otherwise, step 409 is performed;

Step 408: The terminal initiates a process of performing a non-optimized handover, if the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error.

If the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error, the terminal does not perform pre-registration, and then determines the process of initiating the non-optimized handover. . Optionally, after the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error, the terminal re-initiates the pre-registration process. Optionally, the terminal may not perform the process of the non-optimized handover, but does not perform any action. After a period of time, the terminal is disconnected from the link on the network side, so that the waste of air interface resources and the impact on the current service of the LTE network can be reduced.

Step 409: The terminal determines that the communication error of the S101 interface or the S101 interface is a short-term error, and then re-initiates the pre-registration process according to the local policy. In addition, when the terminal determines that the S101 interface or the S101 interface communication error is a short-term error, it is determined that the pre-registration fails, and the pre-registration process may also be abandoned according to the local policy. This embodiment does not impose any restrictions on the local policy.

Through the foregoing steps 401 to 409, the method provided by the embodiment of the present invention is used as an example for the terminal to initiate the pre-registration process, and the method provided by the embodiment of the present invention can ensure that the LTE and HRPD are switched over in the stalk. The S101 interface or the S101 interface communicates incorrectly, correctly notifies the terminal of the switchover failure, and correctly controls the behavior of the terminal to reduce the waste of the air interface resources and the impact on the current service of the LTE network. For details, see the information exchange diagram provided in Figure 13. 1. The UE initiates a pre-registration process (or a handover procedure). 2. The MME determines whether the S101 interface or the S101 interface is in communication error, and determines the cause value of the error. 3. The MME performs long-term and short-term error mapping on the cause value to obtain a mapped value. The eNB sends the mapping value to the eNB through the S1 CDMA2000 tunnel message. The eNB sends a downlink information transmission message carrying the mapping value to the UE, so that the terminal performs the subsequent steps according to the received mapping value and the local policy.

Further, the method provided in this embodiment is that the MME directly maps the cause value of the S101 interface or the S101 interface communication error to obtain a mapping value, and then forwards the mapped value to the terminal through the eNB. Similarly, the network side of the method provided in this embodiment may also send the cause value of the S101 interface or the S101 interface communication error to the eNB, and the eNB maps the received cause value to obtain the mapping value, and then obtains the mapping. The value is sent to the terminal. This embodiment does not impose any restrictions on this.

In summary, in the method provided by the embodiment of the present invention, the MME maps the cause value of the communication error of the S101 interface or the S101 interface to the eNB, and the eNB forwards the mapping value to the terminal, so that the S101 interface or the S101 interface is implemented. When the communication is incorrect, the terminal is correctly notified that the pre-registration fails or the handover fails, and the behavior of the terminal is correctly controlled to reduce the waste of the air interface resources and the impact on the current service of the LTE network.

Example 5

The scenario structure diagram provided in FIG. 5 is taken as an example for description. The difference from the above embodiment is that the terminal performs the handover process as an example. After the MME determines the communication error of the S101 interface or the S101 interface, the failure indication is directly generated. The eNB forwards the failure indication to the terminal, and after receiving the failure indication, the terminal performs the subsequent action according to the local policy, thereby greatly reducing the workload and working pressure of the network side E and the eNB. The method is described in detail, please refer to Figure 14, which reads as follows:

Step 501: The terminal initiates a handover process.

The detailed process of the handover process initiated by the terminal involved in the step can be seen in the LTE to HRPD handover process provided by the prior art, and is not in the prior art.

Step 502: During the handover process, the MME determines whether an error occurs in the S101 interface or the S101 interface communication; if yes, Then, step 503 is performed; otherwise, the subsequent process of the switching process is performed.

In this embodiment, the mobility management entity MME and the mobility management entity of the target network transmit an S101 interface or the S101 interface communication error causes the pre-registration process to fail as an example, causing the pre-registration process to fail and further including the mobile device management entity. For the reasons such as the fault, the embodiment does not limit this.

Step 503: After the MME learns that the S101 interface or the S101 interface communication error occurs, the MME generates a failure indication, and sends the generated failure indication to the eNB.

In the specific implementation, when the MME learns that the S101 interface or the S101 interface communication has an error, the MME generates a failure indication, and sends a downlink SI CDMA2000 Tunnel (DL SI CDMA2000 Tunneling) message to the eNB, where the message carries the message. A failure indication, where the failure indication is used to notify the terminal that the handover process fails.

Step 504: The eNB receives the failure indication sent by the MME, and forwards the failure indication to the terminal.

The eNB can determine that the handover failure of the terminal is based on the received failure indication. And the eNB sends a downlink data transmission (DL Information Transfer) message to the terminal, where the message carries the failure indication.

Step 505: After receiving the failure indication sent by the eNB, the terminal performs subsequent actions according to the local policy.

After receiving the failure indication Failure Indication sent by the eNB, the terminal controls the subsequent behavior according to the local policy. Specifically, after receiving the failure indication, the terminal controls the pre-registration or the handover re-initiation through the timer that is continuously extended until the maximum number of re-registration times (Counter) is reached; or, after receiving the failure indication, the terminal does not initiate the handover. , Stop the triggering of the subsequent switching process.

In this embodiment, an S101 interface error occurs in the handover process as an example. If the S101 interface is incorrect in the pre-registration process, the terminal may directly enter the non-optimized handover state after receiving the failure indication. Optionally, after the terminal determines that the communication error of the S101 interface or the S101 interface is a long-term error, the re-initiation of the pre-registration process is abandoned. Alternatively, the terminal may not perform the process of non-optimized handover, but does not perform any action. After a period of time, the terminal is disconnected from the link on the network side, which can reduce the waste of air interface resources and the impact on the current service of the LTE network.

Further, the foregoing failure indication is further used to indicate that the terminal relinquishes the re-initiation of the pre-registration process or abandons the re-initiation of the network handover procedure;

The terminal determines, according to the received failure indication, that the pre-registration failure or the network handover failure is specifically:

If the terminal performs a pre-registration process, the terminal relinquishes the re-initiation of the pre-registration process according to the received failure indication;

In summary, FIG. 15 is a schematic diagram of information interaction provided by an embodiment of the present invention. 1. UE initiates pre-registration The MME determines whether the S101 interface or the S101 interface is in communication error. 3. The MME sends a failure indication to the eNB through the S1 CDMA2000 tunnel message. 4. The eNB sends a downlink information transmission message carrying the failure indication to the UE. So that the terminal performs the subsequent steps according to the received failure indication and the local policy.

After the MME obtains the communication error of the S101 interface or the S101 interface, the MME generates a failure indication, and the failure indication is forwarded to the terminal by the eNB, and the terminal performs a subsequent processing action according to its own policy, so as to implement The communication on the S101 interface or the S101 interface is incorrect. The terminal is notified that the terminal fails to register in advance or fails to be switched. The behavior of the terminal is correctly controlled to reduce the waste of air interface resources and the impact on the current service of the LTE network. Example 6
