Network access method and communication apparatus

A communication apparatus, wherein the apparatus comprises:

• at least one processor;
• and
• at least one memory storing computer instructions, which when executed by the at least one processor, cause the communication apparatus to:
• obtain an access request, wherein the access request comprises access location information of a first terminal device;
• obtain subscription information of the first terminal device, wherein the subscription information comprises subscription location information;
• obtain allowed information from a second network element in a case that the apparatus determines that the access location information of the first terminal device does not belong to the subscription location information, wherein the allowed information is information indicating whether to allow the first terminal device to access a network at an access location corresponding to the access location information;
• send second indication information to the first terminal device, wherein the second indication information indicates to the first terminal device to establish a session used to communicate with the second network element, the session is used by the first terminal device to send at least one of an identifier of the first terminal device, the access location information of the first terminal device, or third indication information to the second network element, and wherein the third indication information indicates to the second network element to obtain the allowed information;
• and
• allow, based on the allowed information, the first terminal device to access the network at the access location corresponding to the access location information.

A non-transitory computer-readable storage medium, storing computer instructions, wherein when executed by at least one processor, cause an apparatus comprising the at least one processor to:

• obtain an access request, wherein the access request comprises access location information of a first terminal device;
• obtain subscription information of the first terminal device, wherein the subscription information comprises subscription location information;
• obtain allowed information from a second network element in a case that the apparatus determines that the access location information of the first terminal device does not belong to the subscription location information, wherein the allowed information is information indicating whether to allow the first terminal device to access a network at an access location corresponding to the access location information;
• send second indication information to the first terminal device, wherein the second indication information indicates to the first terminal device to establish a session used to communicate with the second network element, the session is used by the first terminal device to send at least one of an identifier of the first terminal device, the access location information of the first terminal device, or third indication information to the second network element, and wherein the third indication information indicates to the second network element to obtain the allowed information;
• and
• allow, based on the allowed information, the first terminal device to access the network at the access location corresponding to the access location information.
