detailed description

FIG. 1 is a flow chart of Embodiment 1 of a method for processing a network access of a mobile terminal according to the present invention. FIG. 2 is a signaling flowchart of Embodiment 1 of a method for processing a network access of a mobile terminal according to the present invention. The executor of this embodiment is the access server of the first type network. As shown in Figures 1 and 2, the method of this embodiment may include:

Step 101, the access server of the first type of network receives the access request of the mobile terminal, the access request carries the International Mobile Subscriber Identity IMSI corresponding to the mobile terminal, and identifies the mobile network number MNC included in the IMSI to obtain The first recognition result.

Specifically, the first type of network is, for example, an LTE network. The scenario of this embodiment is, for example, that a mobile terminal user of operator A with LTE function roams to another country or region, and operator B is a member of the above-mentioned country or region. An operator, A and B have not signed an LTE roaming agreement.

When an LTE mobile terminal enters the LTE network of operator B, it searches for LTE signals preferentially by default. An access server of the LTE network of the first type of network, such as a Mobility Management Entity (MME for short), receives the access request of the mobile terminal, and receives the access request of the mobile terminal. The access request carries an International Mobile Subscriber Identity (IMSI) corresponding to the mobile terminal, and the LTE network identifies the MNC included in the IMSI in the access request of the mobile terminal to obtain a first identification result.

International Mobile Subscriber Identification Number (IMSI for short) is a sign to distinguish mobile terminal users, stored in the mobile terminal's Subscriber Identity Module (SIM) card, and can be used to distinguish valid information of mobile terminal users . Its total length does not exceed 15 digits, and each digit uses a number from 0 to 9. Among them, the Mobile Country Code (MCC) is the code of the country to which the mobile terminal user belongs, which occupies 3 digits, and the MNC occupies 2 digits, and is used to identify the mobile communication network to which the mobile terminal user belongs. The network judges whether the mobile terminal user is a roaming user according to the mobile network number MNC in the IMSI, and uses the MNC as one of the important parameters for addressing the user's Home Location Register (HLR). Different operators have different MNCs. Therefore, the MNC can be used to determine whether operators have signed an international roaming agreement. Since there is no LTE roaming agreement signed between the visited operator B and the operator A to which the mobile terminal belongs, the LTE network cannot recognize the MNC, that is, the first identification result is identification failure, and the mobile terminal will be refused to access the MNC. LTE network.

Step 102, if the first identification result is identification failure, forward the access request to the access server of the second type of network, so that the access server of the second type of network can identify the MNC and receive the access request of the second type of network Enter the second identification result returned by the server; the network of the first category and the network of the second category belong to the same operator.

Specifically, if the first identification result of the LTE network identifying the MNC is identification failure, the LTE network will search for a second type of network of the same operator such as a 3G network, and the access server MME of the LTE network will send the access request to The access server of the 3G network, such as the Mobile Switching Center (MSC for short), performs MNC identification. For example, the access request can be forwarded through the Gateway Mobile Switching Center (GMSC for short), and the 3G network returns the The second identification result, when the 3G network recognizes the MNC of the mobile terminal, the second identification result is successful identification, indicating that the operator to which the mobile terminal belongs has signed a 3G agreement with the operator in the roaming area, and the mobile terminal can choose this operator 3G network access. When the mobile terminal selects the first category network LTE network to access, each LTE network of different operators will inquire whether the corresponding second category network 3G network can allow the mobile terminal to access when rejecting the mobile terminal access. , the mobile terminal writes all operators that refuse access to both the LTE network and the 3G network (the identification result is failure) into the forbidden list, and takes the successfully identified 3G network as the preferred access network.

Step 103, the access server of the first type of network returns the first identification result and the second identification result to the mobile terminal for the mobile terminal to access the network.

Specifically, the access server MME of the LTE network returns the first identification result of the LTE network and the second identification result of the 3G network to the mobile terminal, and the mobile terminal selects a network to access according to the first identification result and the second identification result. If the second identification result is successful identification, the 3G network with successful identification is preferentially selected for access.

In this embodiment, the access server of the first type of network receives the access request of the mobile terminal, the access request carries the International Mobile Subscriber Identity IMSI corresponding to the mobile terminal, and the IMSI included in the Identifying the mobile network number MNC to obtain a first identification result, if the first identification result is identification failure, forwarding the access request to the access server of the second type of network for use by the access server of the second type of network The access server identifies the MNC, and receives a second identification result returned by the access server of the second type of network; the first type of network and the second type of network belong to the same operator; the The access server of the first type of network returns the first identification result and the second identification result to the mobile terminal for the mobile terminal to perform network access, and the mobile terminal is in the process of network access , preferentially select the access server of the second type of network whose second recognition result is a successful recognition, which reduces the access time of the mobile terminal when performing network access, and improves the access success rate, and solves the problem of In the prior art, after the LTE mobile terminal fails to access the LTE network during international roaming, it chooses to authenticate again to a 3G network that has not signed a roaming agreement, and the network access time is long.

In the second embodiment of the method for processing the network access of the mobile terminal of the present invention, on the basis of the embodiment shown in FIG. :

During the access process of the second type of network, the mobile terminal preferentially selects the access server of the second type of network that has been successfully identified for access.

Optionally, if the second identification result is identification failure, performing network access by the mobile terminal includes:

The mobile terminal stores the first identification result and the second identification result indicating that the identification fails in the forbidden list, and during the access process of the second type of network, stops accessing the access server of the second type of network whose identification fails. enter.

Specifically, after the LTE network sends the first identification result and the second identification result to the mobile terminal, the mobile terminal may record the first identification result and the second identification result, and if the second identification result indicates that the identification is successful, the mobile terminal may, for example, The second identification result is the information of the operator of the successfully identified network to form a list, and when the mobile terminal performs a 3G network signal search, compare the successfully identified operator network in the list, for example, the successfully identified network can be preferentially selected according to the signal strength to access. If the second identification result is identification failure, then the mobile terminal stores the first identification result and the second identification result indicating the identification failure in the prohibition list, and the first identification result and the second identification result may also include the operator's identification, And during the access process of the 3G network, stop sending the access request to the access server MSC of the 3G network that fails to be identified.

Access; if the second identification result is identification failure, the mobile terminal's network access includes: the mobile terminal stores the first identification result and the second identification result indicating that the identification failed in the forbidden list, and performs the second type of network access. During the access process, the access to the access server of the second type of network that fails to be identified is stopped, which reduces the access time of the mobile terminal when accessing the network, and improves the access success rate, which solves the existing problem In the technology, after the LTE mobile terminal fails to access the LTE network during international roaming, it chooses to authenticate again to a 3G network that has not signed a roaming agreement, and the network access takes a long time.

Different operators have different MNCs. Therefore, the MNC can be used to determine whether operators have signed an international roaming agreement. Since there is no LTE roaming agreement signed between the visited operator B and the operator A to which the mobile terminal belongs, the LTE network cannot recognize the MNC, that is, the first identification result is identification failure, and the mobile terminal will be refused to access the MNC.

Specifically, if the first identification result of the LTE network identifying the MNC is identification failure, the LTE network will search for a second type of network of the same operator such as a 3G network, and the access server MME of the LTE network will send the access request to The access server of the 3G network, such as the Mobile Switching Center (MSC for short), performs MNC identification. For example, the access request can be forwarded through the Gateway Mobile Switching Center (GMSC for short), and the 3G network returns the The second identification result, when the 3G network recognizes the MNC of the mobile terminal, the second identification result is successful identification, indicating that the operator to which the mobile terminal belongs has signed a 3G agreement with the operator in the roaming area, and the mobile terminal can choose this operator 3G network access. When the mobile terminal selects the first type of network LTE network to access, each LTE network of different operators will inquire whether the corresponding 3G network can allow the mobile terminal to access when the LTE network of different operators rejects the mobile terminal's access, and the mobile terminal will All LTE networks and 3G networks refuse to access (recognition result is failure), the operator writes into the forbidden list, and takes the successfully identified 3G network as the preferred access network.

Step 303, the mobile terminal performs network access according to the first identification result and the second identification result.

Specifically, if the second identification result is that the identification is successful, the mobile terminal preferentially selects the successfully identified 3G network to access.

Optionally, the mobile terminal performs network access according to the first identification result and the second identification result, including:

If the second identification result is that the identification is successful, the mobile terminal preferentially selects an access server of the second type network whose identification is successful during the access process of the second type network;

If the second identification result is identification failure, the mobile terminal stores the first identification result and the second identification result indicating identification failure in the prohibition list, and stops sending information to the identification failure during the access process of the second type of network. The access server of the second type network performs access.

Specifically, if the second identification result is a successful identification, the mobile terminal records the operators of the network whose second identification result is a successful identification, for example, a list can be formed, and when the mobile terminal performs a 3G network signal search, it compares the operators identified in the list. A successful operator network, for example, may preferentially select and access a successfully identified network according to signal strength. If the second identification result is identification failure, then the mobile terminal stores the first identification result and the second identification result indicating the identification failure in the prohibition list, and the first identification result and the second identification result may also include the operator's identification, And during the access process of the 3G network, stop sending the access request to the access server MSC of the 3G network that fails to be identified.
