Step 101: The LTE network side receives the carrier resource information of the eHRPD carrier transmitted by the eHRPD access network through the interface between the LTE network and the LTE network side.

Step 102: The LTE network side converts the eHRPD carrier into an LTE carrier according to the carrier resource information and activates.

Specifically, the LTE network side converts the corresponding eHRPD carrier into an LTE carrier according to the pre-configuration of the LTE network and the frequency band of the carrier resource information, and notifies the terminal in the LTE system parameter message, so that the The LTE carrier operates. After the corresponding eHRPD carrier is converted into the LTE carrier, the LTE network side may further determine the LTE cell and the LTE cell in the overlapping coverage area of the eHRPD network according to the sector identification information in the carrier resource information. The parameter message of the LTE cell is also notified to the terminal.

In the foregoing aggregation method, the process of the aggregation may be initiated by the eHRPD access network or may be initiated by the LTE network side. Specifically, when the LTE network side initiates, the aggregation method may further include the following steps: The LTE network side sends a request message to the eHRPD access network through an interface with the eHRPD access network, requesting available carrier resources of the eHRPD network, The eHRPD access network receives the request message, determines that there is an idle eHRPD carrier or has a releasable eHRPD carrier, and transmits carrier resource information of the idle or releasable eHRPD carrier to the LTE network side.

In addition, the embodiment of the present invention further provides a method for de-aggregating a carrier resource between different systems. As shown in FIG. 2, the method may include the following steps:

Step 201: The LTE network side returns a confirmation message that the corresponding LTE carrier is closed to the eHRPD access network, where the corresponding LTE carrier is an LTE carrier converted by the eHRPD carrier.

Here, if the corresponding LTE carrier is being used, the LTE network side needs to deactivate the corresponding LTE carrier according to the carrier resource information, and then returns the confirmation message; if the corresponding LTE carrier is not Alternatively, the confirmation message can be returned directly to the eHRPD access network. Specifically, the LTE network side deactivating the corresponding LTE carrier according to the carrier resource information may include: the LTE network side, according to the frequency band information and/or the frequency point information in the carrier resource information, the corresponding frequency band and/or frequency point The user on the LTE carrier switches to other available LTE carriers, and deletes the carrier information of the LTE carrier in the LTE system parameter message.

When the eHRPD network load increases and the eHRPD carrier needs to be restored, the above-mentioned carrier resources are de-aggregated, so that the eHRPD network can recover its own carrier resources in time.

Step 301: The eHRPD access network encapsulates the carrier resource information of the eHRPD carrier into a first interface message (such as a RIM message) that interacts with the LTE network side MME, and passes the first interface message to the LTE network side. The interface between the MMEs is sent to the MME of the LTE network;

Here, the interface is preferably a SON function interface between LTE-eHRPDs. The first interface message may specifically be a RIM message or the like.

Step 302: The LTE network side MME receives the first interface message, acquires carrier resource information therein, and encapsulates the carrier resource information into a second interface message that is exchanged between the MME and the evolved base station (eNB, evolved Node B). Transmitting the second interface message to the eNB through an interface with the eNB;

Step 303: The eNB receives the second interface message, obtains carrier resource information from the second interface message, and returns a response message to the MME.

Step 304: The MME receives the response message returned by the eNB, and returns a response message to the eHRPD access network. At this point, the process of transmitting the carrier resource information of the eHRPD carrier to the LTE network by the eHRPD access network ends.
