It should be noted that, the home subscription network element is further configured to, in a case that the terminal is within the target area, reject to respond to the acquisition request from the roaming-site session control network element, and generate the prompt information, where the prompt information is used to prompt that the terminal is in the home.
The technical solution of the present application will now be further explained with reference to an alternative roaming place usage scenario.
Fig. 3 is a schematic diagram of a home-subscribed single stack IPv6 terminal in a roaming area where the single stack network does not support IPv6, as shown in fig. 3, in a roaming area network environment where the single stack network does not support IPv6 (i.e., there is no DNS64 and NAT64), the terminal can normally access IPv4 network resources only through an IPv4 address, and access IPv6 network resources through an IPv6 address. The terminal should be assigned an IPv4/IPv6 dual stack address in this scenario.
Fig. 4 is a schematic flowchart of a process for a terminal to obtain an IP address, as shown in fig. 4, a mobile terminal accesses from a roaming network, initiates a session establishment request, and requests the network to allocate an IP address and DNS information to the terminal; after receiving the terminal request, the session control network element of the roaming place firstly initiates a request for acquiring the terminal number subscription information to the signing network element of the attribution place; after the home signing network element receives the request, judging that the terminal is not in the home network, defaulting that the roaming network does not support the IPv6 single stack, and returning signing information to the roaming session control network element as an IPv4/IPv6 double stack; after the session control network element at the roaming place acquires the subscription information, if only the DNS of IPv6 is configured locally and the address pools are all IPv6, the single stack address of IPv6 is allocated to the terminal, and otherwise, the double stack address of IPv4/IPv6 is allocated to the terminal.
Taking 5GC as an example, after IPv6 single stack modification is performed on the home network, the number is signed as an IPv6 single stack in the UDM. When the terminal moves to the roaming place network, the IP address of the terminal is allocated by the roaming place SMF according to the attribution UDM subscription information. The SMF of the roaming place inquires terminal subscription information from the UDM of the home place; if the home UDM finds that the terminal is in a roaming area network, the subscription attribute returned to the SMF of the roaming area is IPv4/IPv6 double stack; after acquiring the subscription information, the SMF of the roaming place firstly judges the local DNS and IPPOOL configuration, if only the DNS of IPv6 and the address pool of IPv6 are configured, an IPv6 single stack address is allocated to the terminal, and if the DNS of IPv4 and IPv6 are configured, an IPv4/IPv6 double stack address is allocated to the terminal.
It is easy to note that when a mobile terminal subscribed to IPv6 single stack accesses the network at a roaming place without DNS64 and NAT64, the roaming place session control network element first receives an IP session establishment request initiated by the mobile terminal; then, the session control network element of the roaming place inquires the signing network element of the home location of the number, and the signing network element of the home location can acquire the session control network element information of the roaming place in the inquiring process; then the home location signed network element judges the session control network element information as a non-home location session control network element, the default roaming location does not support the IPv6 single stack network, and the user signed attribute returned to the roaming location session control network element is modified from the signed IPv6 single stack to an IPv4/IPv6 double stack; and finally, judging by the session control network element at the roaming place according to the attribute of an IP protocol stack returned by the contract, if the local network supports an IPv6 single stack, namely only the DNS address of IPv6 is configured on the session control network element and only the address segment of IPv6 is configured in the address pool, allocating an IPv6 single stack address to the terminal, and if the local network does not support the IPv6 single stack, namely the DNS addresses of IPv4 and IPv6 are simultaneously configured on the session control network element and the address segment of IPv4 and IPv6 are simultaneously configured in the address pool, allocating an IPv4/IPv6 double stack address to the terminal. Thereby ensuring normal use of mobile terminal services.
It can be understood that, in the present application, according to the location information (in the home network or the roaming network) of the mobile terminal, the home signing network element modifies the IP address protocol type field issued to the roaming session control network element, and at the same time, the roaming session control network element determines the method of allocating the correct IP protocol stack address to the terminal according to the local configuration, which has the advantages that the mobile terminal signing the IPv6 single stack can normally acquire the IP address matched with the network capability of the roaming network in the roaming capability, thereby ensuring the good service perception and reducing the pressure of the traffic between the roaming location and the home location in the home traffic grooming mode; meanwhile, the application of an IPv6 single stack technology can be promoted, and the traffic ratio of IPv6 is improved.

s506, receiving the target stack address returned by the session control network element of the roaming place.
In the method, a terminal detects position information of the terminal, wherein the position information is used for determining that the terminal is in a home location or a roaming location; under the condition that the position information is determined to be in the roaming place, initiating a session establishment request to a session control network element of the roaming place corresponding to the roaming place; the roaming place session control network element is used for generating an acquisition request of first telephone number subscription information of the terminal according to the session establishment request, sending the acquisition request to a home location subscription network element corresponding to the terminal, and generating a target stack address according to second telephone number subscription information provided by the home location subscription network element, wherein the second telephone number subscription information is used for indicating that the subscription attribute of the terminal at the home location corresponding to the terminal is an IPv4/IPv6 dual stack; the method and the device receive the target stack address returned by the session control network element at the roaming place, achieve the purpose that the session control network element at the roaming place issues the target stack address based on the modified signing attribute, thereby achieving the technical effects of avoiding using the IP address allocated by the home location for outgoing, reducing the data processing amount at the home location and avoiding the data flow blockage, and simultaneously, also ensuring the technical purpose that the mobile terminal with the signing attribute of single stack IPv6 can still continue to access the network resources in the roaming place network which does not support IPv6 single stack under the flow grooming mode of the home location for outgoing, thereby solving the technical problems that the data processing is easy to block, the communication instantaneity is poor, the actual service requirements cannot be met and the like due to the mode of allocating the IP address based on the home location for outgoing in the related technology.
