 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. Embodiment 1

 An embodiment of the present invention provides a method for a micro base station to access a network. As shown in FIG. 1, the method includes the following steps:

 Step 101: The micro base station receives a message from the macro base station or the user equipment, and obtains a public land mobile network identifier PLMN ID in the message.

 Step 102: The micro base station queries, according to the PLMN ID, a carrier network URL address or an IP address corresponding to the PLMN ID.

 The above-mentioned micro base station may query a carrier network URL address or an IP address corresponding to the PLMN ID in a database, and the database may be located inside the micro base station or in a third-party network entity, for example, in a server.

The following is a specific example to illustrate the structure of the database. As shown in Table 1, the database stores the correspondence between the PLMN ID and the corresponding carrier network URL address or IP address. The PLMN ID can be queried to the corresponding carrier network URL address or IP address. Since each operator may have multiple PLMN IDs, each PLMN ID in the table will have a corresponding URL address or IP address. Through this database, after the micro base station obtains the PLMN ID, it can be based on the PLMN ID. Obtain the corresponding carrier network URL address or IP address to ensure that the micro base station can successfully access the carrier's network.

Figure imgf000005_0001
Optionally, when the PLMN ID obtained by the micro base station from the macro base station or the user equipment message cannot be queried in the database, the micro base station automatically adds the PLMN ID to the database, thereby updating the record of the database.

 Step 103: The micro base station accesses the operator network corresponding to the URL address or the IP address.

 Optionally, before the micro base station accesses the operator network corresponding to the URL address or the IP address, the method further includes:

 The micro base station receives the identity verification of the micro base station by the operator network corresponding to the URL address or the IP address, so as to access the carrier network after the identity verification by the carrier network.

 After obtaining the carrier network URL address or IP address, the micro base station initiates a request to access the operator network. Optionally, the micro base station obtains the carrier network URL address or IP address, and before accessing the carrier network. The operator will authenticate the micro base station that requires access to the carrier network. Only the micro base station through which the identity authentication passes can access the operator's network to ensure network security. The specific steps of the identity verification are as follows:

The micro base station sends an identity verification message to the operator network, so that the operator network confirms whether the micro base station can be verified by the operator network according to the identity verification message; Receiving, by the micro base station, an identity verification response message sent by the operator network, where the identity verification response message includes information about whether the micro base station is verified by the operator network;

 After the micro base station is authenticated by the operator network, the micro base station can access the operator network. When the micro base station requests access from the operator network, the operator network authenticates the micro base station to ensure the security of the network, and prevents other unauthenticated micro base stations from accessing the network of the operator. After the micro base station obtains the PLMN ID and queries the corresponding operator's URL address and IP address according to the PLMN ID, if the operator network is accessed without authentication, the operator network may be brought a security risk.

 Optionally, the micro base station stores a correspondence between the PLMN ID and the URL address or an IP address; the micro base station periodically updates a correspondence between the PLMN ID and the URL address or an IP address. .

 In the following, for the case where the micro base station obtains the PLMN ID from the macro network or the client device, a more specific example will be described separately.

 Optionally, before the micro base station receives the message sent by the macro base station through the broadcast control channel BCCH, the micro base station obtains the frequency point of the macro base station by scanning within the frequency range supported by the micro base station, and then uses the same frequency as the macro base station. Point, establish a connection with the macro base station.

 Optionally, when the macro base station is more than one, the micro base station needs to acquire the PLMN ID in the message sent by each macro base station, and the micro base station may obtain the carrier network URL address or IP corresponding to the first acquired PLMN ID. The address is connected to the carrier network.

 As shown in Figure 2, the above complete implementation steps can be described as follows:

 Step 201: The micro base station scans and obtains the working frequency of the macro base station in the frequency range supported by the micro base station, and then uses the same frequency point as the macro base station to establish a connection with the macro base station.

Step 202: The micro base station receives a message sent by the macro base station by using the BCCH. Step 203: The micro base station parses the message to obtain a PLMN ID in the message.

 Step 204: The micro base station queries whether there is a URL address and an IP address of the carrier network corresponding to the PLMN ID, if yes, step 205 is performed;

 Step 205: The micro base station accesses the network of the operator according to the URL address and the IP address.

Optionally, in step 204, if the micro base station cannot query the URL address and the IP address of the carrier network corresponding to the PLMN ID, the micro base station replaces a frequency point in the frequency range supported by the micro base station.

Figure imgf000007_0001

When the micro base station receives the message from the UE, acquiring the PLMN ID in the message includes: receiving, by the micro base station, a location update request message of the UE; the micro base station receiving the identity response message replied by the UE, and obtaining the identifier response message The PLMN is optional. Before the micro base station receives the location update request message of the UE, a wireless connection must be established between the micro base station and the UE.

 The micro base station may establish a wireless connection with multiple UEs, and the micro base station needs to obtain the PLMN ID sent by some or all UEs.

 The user equipment in this example is described by taking the UE as an example. In other systems, the user equipment may also be an MS or the like.

 As shown in Figure 3, the above complete implementation steps can be described as follows:

 Step 301: The micro base station selects a working frequency point in a frequency range supported by the micro base station. Step 303: The micro base station receives a location update request message of the UE.

Step 304: The micro base station sends an identifier request message to the UE. Step 305: The micro base station receives the identifier response message replied by the UE, and obtains the PLMN ID in the identifier response message.

 Step 306: The micro base station queries whether there is a URL address and an IP address of the carrier network corresponding to the PLMN ID, if yes, step 307 is performed;

 Step 307: The micro base station accesses the network of the operator according to the URL address and the IP address.

 Optionally, the micro base station can establish a wireless connection with more than one user equipment, and the micro base station obtains the PLMN ID sent by all the user equipments. The micro base station is obtained according to the first

The carrier network URL address or IP address corresponding to the PLMN ID is connected to the carrier network.

Optionally, in step 306, if the micro base station cannot query the URL address and the IP address of the carrier network corresponding to the PLMN ID, the micro base station can replace the frequency in the frequency range supported by the micro base station.

Figure imgf000008_0001

 Optionally, in step 305, if the micro base station cannot parse the PLMN ID from the message, the micro base station may also replace a frequency point in the frequency range supported by the micro base station, and perform step 301-step 307 again. .

 In practical applications, the first five digits of the IMSI are the PLMN ID of the operator. Because the identifier response message includes the IMSI, the micro base station can obtain the PLMN ID by using the identifier response message.

 According to the method of the first embodiment of the present invention, the micro base station can obtain the PLMN ID (Public Land Mobile Network Identity) of the operator network that needs to be accessed from the surrounding macro base station or the user equipment, and according to The PLMN ID queries the carrier network URL address or IP address corresponding to the PLMN ID, and accesses the carrier network corresponding to the URL address or the IP address.
