Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and 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, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a network connection method and related equipment, which are used for accessing a mobile network by terminal equipment when the terminal equipment is out of the coverage range of the mobile network. The following are detailed below.

In a conventional mobile network, communication between terminal devices needs to pass through a core network entity, such as a Serving Gateway (SEW), a Packet Data network Gateway (PGW), and so on. When two terminal devices which are relatively close to each other need to communicate, the communication efficiency is reduced because the communication needs to be realized through a core network entity. Therefore, in order to improve the communication efficiency between two terminals located close to each other, a Proximity Services (ProSe) problem has been proposed in the art, in which two terminals located close to each other can directly communicate with each other. When the terminal device is out of the coverage area of the mobile network, the terminal device cannot access the mobile network, and because the ProSe issue can provide a direct communication function for the two terminal devices, the terminal device out of the coverage area of the mobile network can access the mobile network through the terminal device in the coverage area of the mobile network, but the two terminal devices are required to have the same access point accessing the same mobile network. The mobile network in the embodiment of the present invention refers to an operator network, and the terminal device is outside the coverage of the mobile network, which indicates that the terminal device is outside the coverage of all operator networks at this time and that there is no available non-operator network currently.

When the home mobile network of the first terminal device within the coverage of the mobile network and the home mobile network of the second terminal device outside the coverage of the mobile network are both target mobile networks, the server corresponding to the target mobile network may set access points for accessing the target mobile network for the two terminal devices in advance, when the second terminal device needs to access the target mobile network, the second terminal device will receive access point information corresponding to the access point, which is broadcasted by the first terminal device and used for accessing the target mobile network, of the first terminal device, and then the second terminal device will determine access point information from the access point information belonging to both the access point corresponding to the access point, which is used for accessing the target mobile network, of the first terminal device and the access point information corresponding to the access point, which is used for accessing the target mobile network, of the second terminal device, and sending the access point information to the first terminal device, and the first terminal device accessing the target mobile network through the access point corresponding to the access point information, so that the second terminal device can access the target mobile network through the first terminal device. However, in the above-mentioned method, the server is required to set access points for the managed terminal devices in advance, but the terminal devices do not use these access points to access the mobile network all the time, which causes resource waste; furthermore, it is required that the home mobile network of the terminal device which is out of the coverage of the mobile network is the same mobile network as the home mobile network of the terminal device which is in the coverage of the mobile network, and the currently available mobile network of the terminal device which is in the coverage of the mobile network must include the home mobile network of the terminal device. Therefore, when the server does not provide the terminal device with an access point for accessing the mobile network in advance, or the home mobile network of the terminal device out of the coverage of the mobile network and the home mobile network of the terminal device in the coverage of the mobile network are different mobile networks, or the currently available mobile network of the terminal device in the coverage of the mobile network does not include the home mobile network of the terminal device, the terminal device out of the coverage of the mobile network cannot access the mobile network through the terminal device in the coverage of the mobile network.

Referring to fig. 1, fig. 1 is a flowchart illustrating a network connection method according to an embodiment of the present invention. The network connection method shown in fig. 1 is described from the perspective of a terminal device within the coverage of a mobile network. As shown in fig. 1, the network connection method may include the following steps.

S101, a first terminal device sends an identifier of a first mobile network to a server, wherein the first terminal device is within the coverage range of the first mobile network, and the server is a server corresponding to a home mobile network of the first terminal device.

In this embodiment, the first terminal device may access the mobile network through the access point, and therefore, in order to access the mobile network, the first terminal device needs to send an identifier of the mobile network currently available to the first terminal device, that is, an identifier of the first mobile network, to the server. The first terminal equipment is located in the coverage range of the first mobile network, and the server is a server corresponding to the home mobile network of the first terminal equipment. The first mobile network may be a home mobile network of the first terminal device, or may be another mobile network, which is not limited in this embodiment. For example, when the SIM card used by the first terminal device is a china unicom card, the home mobile network of the first terminal device is a china unicom network, the server is a server corresponding to the china unicom network, and when the first terminal device is currently only located in the coverage area of the china telecommunication network, the identifier of the first mobile network is an identifier of the china telecommunication network. The first terminal device is any terminal device within the coverage range of the mobile network.

S102, the first terminal device receives first access point information sent by the server, wherein the first access point information comprises access point information obtained by the server according to the identification of the first mobile network.

In this embodiment, after sending the identifier of the first mobile network to the server, the first terminal device receives first access point information sent by the server, where the first access point information includes access point information obtained by the server according to the identifier of the first mobile network. Wherein. When the first terminal device is in the coverage area of the first mobile network, the first terminal device may directly access the first mobile network through the access point corresponding to the access point information obtained by the server according to the identifier of the first mobile network.

S103, the first terminal device sends second access point information to the second terminal device, wherein the second terminal device is out of the coverage area of the mobile network, and the second access point information is part or all of the first access point information.

In this embodiment, after receiving the first access point information sent by the server, the first terminal device may send part or all of the access point information in the first access point information to the second terminal device. The second terminal device is located outside the coverage of the mobile network, and the second terminal device is any terminal device located outside the coverage of the mobile network.

S104, the first terminal equipment receives a network connection request which is sent by the second terminal equipment and carries third access point information, wherein the third access point information belongs to one of the second access point information and the access point information which can be used by the second terminal equipment.

In this embodiment, the third access point information is one access point information determined by the second terminal device from access point information belonging to both the second access point information and the second terminal device usable access point information. When the first access point information only includes access point information obtained by the server according to the identifier of the first mobile network, the second terminal device may use the access point information as access point information corresponding to an access point which the second terminal device may use for accessing the first mobile network, that is, when the second terminal device is within the coverage of the first mobile network, the second terminal device may directly access the first mobile network through the access points corresponding to the access point information.

And S105, the first terminal equipment accesses the first mobile network through the access point corresponding to the third access point information.

In this embodiment, after receiving a network connection request carrying third access point information sent by a second terminal device, a first terminal device accesses to a first mobile network through an access point corresponding to the third access point information, and then the second terminal device accesses to the first mobile network through the first terminal device.

In one embodiment, the first terminal device receives first access point information sent by a server, and also receives an identifier of a second mobile network equivalent to the first mobile network, where the identifier of the second mobile network is sent by the server, and the first access point information further includes access point information obtained by the server according to the identifier of the second mobile network;

after the first terminal device receives the first access point information sent by the server and before the second terminal device sends the second access point information, the network connection method may further include the steps of:
