Example 2

 Referring to FIG. 3, a method for obtaining pre-registration information is provided in this embodiment. In this embodiment, a base station may be a base station in an LTE network, and a current cell where the UE is located may be a cell controlled by the base station, and the target cell may be It is a cell in a CDMA2000 network. It should be noted that this embodiment can be applied to the following two situations:

 First, this scheme can be used when configuring pre-registration information in the base station for the first time.

 Second, if the pre-registration information has been configured in the base station, but the pre-registration information is invalid (invalid due to expiration, etc.), and the pre-registration information needs to be updated, the scheme can be used.

 A method for obtaining pre-registration information provided in this embodiment includes:

 301: When the base station detects the physical cell identifier of the target cell that the UE wants to switch, the UE sends a measurement message to the UE, where the measurement message indicates that the UE reads the identifier of the target cell.

 For example, the identifier of the target cell may be a cell global identity (CGI).

 In this embodiment, the physical cell identifier PCI (physical cell ID) and CGI are different in:

PCI is a basic parameter of wireless network configuration. It is used to distinguish wireless signals of different cells. For example, the number can be 0-503. The physical cell identifier can distinguish wireless signals. No. different cell;

 CGI is used to uniquely identify a cell on a global scale.

 It should be noted that the manner in which the base station detects the physical cell identifier of the target cell belongs to the prior art, and details are not described herein again.

 302: The UE reads the identifier of the target cell.

 303: The UE sends the identifier of the target cell to the base station.

 The base station detects, according to the identifier of the target cell and the identifier of the current cell where the UE is located, whether the local pre-registration information corresponding to the identifier of the current cell where the UE is located and the identifier of the target cell are stored.

 In this embodiment, in the process of providing a service for the UE, the base station saves the identifier of the current cell where the UE is located.

 The pre-registration information is only related to the current cell and the target cell where the UE is located, that is, the pre-registration information has a unique correspondence with the identifier of the current cell where the UE is located and the identifier of the target cell, so the base station can be based on the current cell where the UE is located. The identifier and the identifier of the target cell find pre-registration information corresponding to the identifier of the current cell where the UE is located and the identifier of the target cell.

 It should be noted that each pre-registration information saved by the base station has an expiration date, and the pre-registration information is unavailable after being expired. After the base station obtains the pre-registration information, an expiration date may be set for each pre-registration information obtained. The pre-registration information is valid pre-registration information during the validity period.

 305: When the base station detects that the local pre-registration information corresponding to the identifier of the current cell and the identifier of the target cell where the UE is located is not stored, the first message is sent to the MME (Mobility Management Entity).

 The first message includes the identifier of the current cell where the UE is located and the identifier of the target cell. The current cell where the UE is located is a cell in the LTE network, and the first message is used to instruct the HRPD AN to generate pre-registration information.

 In this embodiment, the base station detects that the local pre-registration information corresponding to the identifier of the current cell and the identifier of the target cell where the UE is located is not stored in the following two types;

First, the base station does not find the identity and target cell of the current cell where the UE is located. Pre-registration information corresponding to the identifier;

 Second, the base station finds pre-registration information corresponding to the identity of the current cell where the UE is located and the identity of the target cell, but the found pre-registration information has expired.

 306: After receiving the first message, the MME adds the tracking area identifier of the MME to the first message.

 The tracking area identifier of the MME is used to uniquely identify the MME that sends the first message.

 Optionally, the MME may add the tracking area identifier to the head or the tail of the first message.

 307: The MME sends the first message after adding the tracking area identifier to the HRPD AN.

308: After receiving the first message after adding the tracking area identifier sent by the MME, the HRPD AN generates pre-registration information according to the identifier of the current cell in which the UE is located in the first message after adding the tracking area identifier and the identifier of the target cell.

 Specifically, the HRPD AN is pre-stored with a pre-registration information list corresponding to the identifier of the current cell where the UE is located and the identifier of the target cell, where the HRPD AN is based on the identifier of the current cell where the UE is located and the identifier of the target cell. The corresponding pre-registration information is found in the list.

 For example, as shown in the following table, it is the corresponding list of the identity of the current cell where the UE is located, the identification of the target cell, and the pre-registration information:

 For example, in this embodiment, the current cell where the UE is located is the current cell 1 and the target cell is the target cell 2, and the HRPD AN searches for the list of the current cell 1 and the identifier of the target cell 2, and the obtained pre-registration information is the second. Pre-registration information.

 The pre-registration information in this embodiment is used to identify the pre-registration area and to indicate whether the UE is allowed to pre-register in the pre-registration area, including:

Pre-registration permission indication: Indicate whether to allow the UE to initiate a pre-registration operation; Pre-registration area identifier: Color code of CDMA2000 reference cell (HRPD reference cell);

 Secondary pre-registration area identifier: Secondary color code of the CDMA2000 reference cell (HRPD reference cell).

 309: The HRPD AN sends the second message to the MME corresponding to the tracking area i or the identifier according to the tracking area identifier.

 The second message includes pre-registration information, an identifier of a current cell where the UE is located, and an identifier of the target cell.

 After receiving the second message, the MME sends the second message to the base station corresponding to the identifier of the current cell where the UE is located, according to the identifier of the current cell where the UE is located in the second message.

 The identifier of the current cell where the UE is located includes the information about the base station corresponding to the current cell where the UE is located. Therefore, the MME can obtain the base station corresponding to the current cell where the UE is located according to the identifier of the current cell where the UE is located.

 311: After receiving the second message sent by the HRPD AN, the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell.

 The base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, where the base station establishes pre-registration information, the correspondence between the identifier of the current cell where the UE is located, and the identifier of the target cell, and The pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell are stored.

 It should be noted that, when the current cell where different UEs are located and the target cell to be switched to are the same, the pre-registration information used by different UEs in performing the pre-registration operation is the same pre-registration information. Therefore, the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, so that different UEs (the current cell where the different UE is located and the target cell to be switched to are the same) are executed. Before the pre-registration operation, the base station may obtain the pre-registration information required by the UE according to the identifier of the current cell where the UE is located and the identifier of the target cell.

Therefore, for different UEs, when the current cell in which the different UEs are located and the target cell to be handed over are the same, the pre-registration information used by different UEs in performing the pre-registration operation is the same pre-registration information. It should be noted that, after the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, the base station sends the pre-registration information to the UE, so that the UE initiates the pre-registration operation.

 With the method for obtaining the pre-registration information provided by the embodiment, when the base station acquires the pre-registration information for the first time or needs to obtain the updated pre-registration information, the base station can automatically send the first message to the HRPD AN, where the first message includes the UE. The identifier of the current cell and the identifier of the target cell; the HRPD AN generates the pre-registration information according to the first message after receiving the first message, and sends the second message to the base station, where the second message includes the pre-registration information and the current cell where the UE is located. The identifier and the identifier of the target cell, the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell. Compared with the prior art, in the method provided by the embodiment, when the base station acquires the pre-registration information for the first time or needs to obtain the updated pre-registration information, the HRPD AN can generate the pre-registration information and send it to the base station, and does not need to be artificially at the base station. The pre-registration information is configured on the network, thereby simplifying the process of the base station acquiring the pre-registration information. Example 3

 Referring to FIG. 4, a method for obtaining pre-registration information is provided in this embodiment. In this embodiment, a base station is a base station in an LTE network, a current cell where the UE is located is a cell under the base station, and a target cell is a CDMA2000 network. It should be noted that the present embodiment can be applied to the case where the base station acquires the pre-registration information again after the UE fails to perform the pre-registration operation.

 A method for obtaining pre-registration information provided in this embodiment includes:

 401: The UE sends a pre-registration failure indication, a pre-registration failure reason, and an identifier of the target cell that the UE switches to the base station.

 The reason for the pre-registration failure is that the pre-registration area is unavailable or the pre-registration area is unsuccessful.

 It should be noted that the identifier of the cell in this embodiment may be the cell identifier.

CGI.

402: The base station generates a first message according to the pre-registration failure indication, the pre-registration failure reason, the identifier of the current cell where the UE is located, and the identifier of the target cell. In this embodiment, in the process of providing a service for the UE, the base station saves the identifier of the current cell where the UE is located.

 The first message includes an identifier of the current cell where the UE is located, an identifier of the target cell, a pre-registration failure indication, and a pre-registration failure reason. The first message is used to instruct the HRPD AN to generate pre-registration information.

 403: The base station sends a first message to the MME.

 404: After receiving the first message, the MME adds the tracking area identifier of the MME to the first message.

 The tracking area identifier of the MME is used to uniquely identify the MME that sends the first message.

 Optionally, the MME may add the tracking area identifier to the head or the tail of the first message.

 405: The MME sends a first message after adding the tracking area identifier to the HRPD AN. 406: After receiving the first message after adding the tracking area identifier sent by the MME, the HRPD AN, according to the identifier of the current cell where the UE is located in the first message after adding the tracking area identifier, the identifier of the target cell, the pre-registration failure indication, and Pre-registration failure reason generates pre-registration information.

 Specifically, the HRPD AN learns that the base station needs to re-acquire the pre-registration information according to the pre-registration failure indication and the pre-registration failure reason, and then the HRPD AN is again in the above list according to the identifier of the current cell where the received UE is located and the identifier of the target cell. Find the corresponding pre-registration information. The pre-registration information list corresponding to the identifier of the current cell where the UE is located and the identifier of the target cell is pre-stored in the HRPD AN.

 It should be noted that, in the foregoing method, the foregoing HRPD AN finds the corresponding pre-registration information in the foregoing list according to the identifier of the current cell where the UE is located and the identifier of the target cell, and the HRPD AN receives the method according to the step 308 in the second embodiment. The method of finding the corresponding pre-registration information in the above list is the same as the method of the current cell identifier of the UE to which the UE is located and the identifier of the target cell, and is not specifically described herein.

 The pre-registration information in this embodiment is used to identify the pre-registration area and to indicate whether the UE is allowed to pre-register in the pre-registration area, including:

Pre-registration permission indication: Indicate whether to allow the UE to initiate a pre-registration operation; Pre-registration area identifier: the color code of the CDMA2000 reference cell (HRPD reference cell);

 Secondary pre-registration area identifier: Secondary color code of the CDMA2000 reference cell (HRPD reference cell).

 407: The HRPD AN sends a second message according to the tracking area identifier to the MME corresponding to the tracking area i or the identifier.

 The second message includes pre-registration information, an identifier of a current cell where the UE is located, and an identifier of the target cell.

 408: After receiving the foregoing second message, the MME sends the second message directly to the base station corresponding to the identifier of the current cell where the UE is located, according to the identifier of the current cell where the UE is located in the second message.

 The identifier of the current cell where the UE is located includes the information of the base station corresponding to the current cell in which the UE is located. Therefore, the MME can obtain the base station corresponding to the identifier of the current cell where the UE is located according to the identifier of the current cell where the UE is located.

 409: After receiving the second message sent by the HRPD AN, the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell.

 The base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, where the base station establishes pre-registration information, the correspondence between the identifier of the current cell where the UE is located, and the identifier of the target cell, and The pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell are stored.

 It should be noted that, when the current cell where different UEs are located and the target cell to be switched to are the same, the pre-registration information used by different UEs in performing the pre-registration operation is the same pre-registration information. Therefore, the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, so that different UEs (the current cell where the different UE is located and the target cell to be switched to are the same) are executed. Before the pre-registration operation, the base station may obtain the pre-registration information required by the UE according to the identifier of the current cell where the UE is located and the identifier of the target cell to which the UE is to be handed over.

Therefore, after the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell, the base station sends the pre-registration information to the UE, so that the UE initiates the pre-registration operation. With the method for obtaining pre-registration information provided by the embodiment, after the base station obtains the pre-registration information again, the base station can obtain the pre-registration failure indication and the pre-registration failure reason sent by the UE, Generating a first message, and sending a first message to the HRPD AN. After receiving the first message, the HRPD AN generates pre-registration information according to the first message, and sends the second message to the base station, where the second message includes pre-registration information, where the UE is located. The identifier of the current cell and the identifier of the target cell, and the base station associates and stores the pre-registration information, the identifier of the current cell where the UE is located, and the identifier of the target cell. Compared with the prior art, when the UE fails to reacquire the pre-registration information after the UE performs the pre-registration operation, the embodiment can implement the HRPD AN according to the base station after the UE fails to perform the pre-registration operation. A message regenerates the pre-registration information and sends the information to the base station, so that the base station can re-acquire the pre-registration information. When the base station obtains the pre-registration information, the base station does not need to manually configure the pre-registration information on the base station, which simplifies the base station acquiring the pre-registration information. process.
