Description

A service access method in packet domain

technical field

The invention relates to the mobile network field of the packet domain, in particular to a service access method of the packet domain.

Background technique

Currently, for mobile networks in the packet domain, each mobile network includes a radio access network and a core network. The core network mainly includes: Serving General Packet Radio Service Support Node (SGSN, ServingGPRS Support Node), Gateway GPRS Support Node (GGSN, Gateway GPRS SupportNode), Home Location Register (HLR, Home Location Register), Short Message Service Center (SMSC, Short Message Service Centre), service control point (SCP, Service ControlPoint), etc., different mobile networks design and realize their own operation modes through their respective bearer service platforms, such as GGSN, HLR, SMSC, SCP, etc., to provide users with Business with its own characteristics. The above-mentioned different mobile networks generally refer to mobile networks operated by different operators.

The coverage of different mobile networks may be different. When a user belonging to a certain mobile network goes beyond the coverage of its own network and enters the coverage of other mobile networks and initiates an access request, the SGSN of the network receives the received After entering the request, it will find that the user does not belong to the network, and thus reject the user's access request, so that the user cannot perform services in other networks except the network to which the user belongs.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a service access method in the packet domain, so that users can enjoy services not only within the coverage of their own mobile network, but also within the coverage of other mobile networks.

In order to achieve the above object, technical solution of the present invention is achieved in that way:

A service access method in a packet domain, the method comprising:

After signing a contract with the shared network, the mobile network becomes the contracted network of the shared network, the shared network records the network identification of the contracted network, and configures the number of resources occupied by each contracted network on the shared network;

The user moves to the shared network and initiates a service request. After the shared network receives the service request, it judges whether the mobile network to which the user belongs is a contracted network according to the recorded contracted network identifier and the network identifier carried in the service request message. If so, judges whether the user belongs to Whether the number of resources occupied by the contracted network of the shared network is greater than the number of resources configured at the time of signing, if not, access the user; otherwise, deny access.

The number of resources occupied by the shared network configured by the contracted network on the shared network is: configured on the general packet radio service support node SGSN of the shared network.

The number of resources configured on the shared network is: the number of simultaneously accessed users, the number of simultaneously activated packet data protocols, the number of simultaneously accessed prepaid users, traffic, or any combination of the above.

When the number of resources configured on the shared network is more than one, the specific process of the shared network judging whether the number of resources of the shared network occupied by the subscription network to which the user belongs is greater than the number of resources configured at the time of signing is: Whether the number of various resources occupied by the contracted network is greater than the corresponding number of resources configured at the time of signing, as long as one judgment result is yes, the access will be rejected; if all judgment results are no, the user will be connected.

After the sharing network receives the service request and before judging whether the mobile network to which the user belongs is a contracted network, the sharing network further includes: the sharing network judges whether the mobile network to which the user belongs is the own network, and if so, accesses the user, and this process ends, otherwise, Continue to judge whether the mobile network to which the user belongs is its own contracted network;

Alternatively, after the sharing network determines that the mobile network to which the user belongs is not its own contracted network, the sharing network further includes: the sharing network determines whether the mobile network to which the user belongs is the own network, and if so, accesses the user; otherwise, denies access.

The signing of the mobile network with the shared network is: the mobile network signs with the SGSN of the shared network, and,

The judging whether the mobile network to which the user belongs is a subscribed network is performed by the SGSN of the shared network.

The access user is completed by the wireless access network of the shared network, or part of the core network, or a combination of the two; and, the part of the core network is an SGSN, or a gateway GPRS support node GGSN, or a combination of the two .

Compared with the prior art, the method provided by the present invention becomes the contracted network of the shared network after signing a contract with the shared network through the mobile network. Users of the network can access not only within the coverage of their own network, but also within the coverage of the contracted shared network, which expands the area where contracted network users enjoy services and facilitates users. In addition, according to the method proposed by the present invention, when a small operator builds a network, it can also only build a bearer service platform, without building access network equipment and some core network equipment, and realize access by means of the shared network equipment of a large operator. to reduce costs.

Detailed ways

Since the wireless access network and part of the core network of the mobile network are only responsible for user access and have nothing to do with the specific realization of services, the specific realization of services is completed by the bearer service platform. Therefore, the present invention proposes a method of sharing the network equipment that is only responsible for access with other mobile networks, for example: after mobile network A shares its wireless access network and part of the core network with other mobile networks, other mobile networks such as mobile The network B can use the mobile network A to realize the access of the users belonging to the mobile network B, and then the bearer service platform of the mobile network B can realize the specific services required by the users. Here, a mobile network that can share part of its own network equipment with other mobile networks is called a shared network.

The shared network equipment can be the radio access network, part of the core network or both. The wireless access network mainly refers to base stations and wireless controllers, and part of the core network mainly refers to SGSN, GGSN, etc.

The core idea of the present invention is: after signing a contract with the shared network, the mobile network becomes the contracted network of the shared network; the user moves to the shared network and initiates a service request; after the shared network receives the user's service request, it Determine whether the mobile network to which the user belongs is the contracted network of the user, if so, access the user; otherwise, reject the access.

It can be seen from the above that the contracted network is the mobile network of the shareable equipment that subscribes to the shared network so as to use the shared network. The shared network can not only be responsible for accessing users who subscribe to the network, but also be responsible for accessing users belonging to its own network.

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is the flow chart of the specific embodiment 1 of the service access method of the packet domain provided by the present invention, as shown in Fig. 1, its specific steps are as follows:

Step 101: The mobile network becomes a contracted network of the shared network after signing a contract with the shared network.

Here, the shared network needs to record the network identifier of the contracted network.

Step 102: The user moves to the shared network and initiates a service request.

The service request message carries the network identifier.

Step 103: The shared network receives the user's service request, and judges whether the mobile network to which the user belongs is its own contracted network according to the network identifier carried in the service request message, and if so, accesses the user; otherwise, rejects the user's access.

After the shared network accesses the user of the contracted network, according to the network identifier, the user's service request is sent to the corresponding contracted network, and the contracted network completes the corresponding service.

Since the resources of the shared network are limited, it may simultaneously access users belonging to multiple contracted networks, and may also access its own network users at the same time. For the access of other contracted network users or its own network users, the shared network can limit the resources occupied by the contracted network. The restrictions can be: the number of users of the contracted network simultaneously accessing itself, and the packet data protocol of the contracted network activated by itself at the same time (PDP, PacketData Protocol) number, the number of prepaid users who are simultaneously connected to the contracted network, the traffic occupied by the contracted network, etc. As shown in Figure 2, the specific steps are as follows:

Step 201: After the mobile network signs a contract with the SGSN of the shared network, it becomes the contracted network of the shared network, and at the same time configures the number of resources occupied by the shared network on the SGSN of the shared network. The number of resources can be configured through negotiation between the subscription network and the sharing network, or can be configured by the subscription network in the sharing network, or can be configured by the sharing network according to the subscription status of the subscription network.

Similarly, the SGSN of the shared network shall record the network identification of the contracted network.

The resources referred to here can be one or a combination of the number of simultaneously accessed users, the number of simultaneously activated PDPs, the number of simultaneously accessed prepaid users, and traffic.

Step 202: The user moves to the shared network and initiates a service request.

The service request message carries the user ID, and the user ID includes the network ID.

Step 203: The SGSN of the shared network receives the service request, and judges whether the mobile network to which the user belongs is its own contracted network according to the user identifier carried in the service request message, and if so, executes step 204; otherwise, sends an access rejection message to the user, This process ends.

The user identification carried in the service request message usually refers to the International Mobile Subscriber Identity (IMSI, International Mobile Subscriber Identity), and the front part of the IMSI is identified by the network, namely the mobile country code (MCC, Mobile Country Code) and the mobile network code (MNC, MobileNetwork Code) composition. The SGSN of the shared network compares the network identifier carried in the service request message with the saved subscribed network identifier, and can know whether the mobile network to which the user belongs is its own subscribed network according to the comparison result. The shared network can also determine whether the mobile network to which the user belongs is its own contracted network by checking whether the network identifier carried in the service request message is found in the subscribed network identifier recorded by the shared network.

Step 204: The SGSN of the shared network counts the resource value of the shared network occupied by the contracted network, and sets the obtained statistical value to m.

Step 205: The SGSN of the shared network judges whether m is greater than the number of corresponding resources occupied by the shared network configured in step 201, and if so, sends an access rejection message to the user; otherwise, accesses the user.

From the above, there should be a one-to-one correspondence between the resources of the shared network occupied by the contracted networks that need to be counted and the resources configured in step 201, which may be one type of resource or a combination of more than one type of resources. If it is a combination of resources, multiple statistical values are obtained. If there are multiple statistical values, compare each statistical value with the corresponding configuration value, and as long as one of them exceeds the range, the access will be rejected; only when each statistical value is within the range of the corresponding resource number configured, the user will be allowed access.

When the shared network sends a request rejection message to the user, it may also notify the mobile network to which the user belongs that the shared resource applied for is insufficient and needs to apply for more resources. The shared network can determine the network usage fee charged for it according to the number of resources applied for by the contracted network.

In addition, in the specific embodiments 1 and 2, if the shared network is also responsible for accessing its own network users, then after the shared network receives the service request, before step 103 or step 203, the shared network can first determine the mobile network to which the user belongs. Whether the network is the own network, and if so, access the user, and the process ends; otherwise, judge whether the mobile network to which the user belongs is the contracted network of the user, that is, execute step 103 or step 203. Or, after step 103 or step 203, that is, after the shared network determines that the mobile network to which the user belongs is not its own contracted network, it further judges whether the mobile network to which the user belongs is its own network, and if so, accesses the user; otherwise, rejects the connection. enter.

The above descriptions are only process and method embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
