Example
[0080] Example 1
[0081] In this example, the type of APN information is specifically NI information, and its content is A, and the type of QoS information is specifically ARP information, and its content is ARP-1.
[0082] meets the figure 2 requirements of the first item.
[0083] In this case, the specific content of the TFT rule selected by the PGW in step S302 is:
[0084] The source IP is IP-1 and the destination port is port 1.
[0085] That is, on the default bearer, filter the service flows that do not meet any of the conditions.
Example
[0086] Example 2
[0087] In this example, the type of APN information is specifically NI information, and its content is A, and the type of QoS information is specifically QCI information, and its content is QCI-2.
[0088] meets the figure 2 the third requirement in which, although figure 2 The content of QoS shown in is two items (ARP information content and QCI information content), but the QoS information received in step S301 only includes QCI information without ARP information. Therefore, as long as the requirements of QCI information content are met, it will be regarded to meet the requirements of this option.
[0089] In this case, the specific content of the TFT rule selected by the PGW in step S302 is:
[0090] The source port is port 2, and the destination port range is port 7~8.
[0091] That is, on the default bearer, filter the service flows that do not meet any of the conditions.
Example
[0092] Example three
[0093] In this example, the type of APN information is specifically OI information, and its content is B, and the type of QoS information is specifically ARP information, and its content is ARP-3.
[0094] meets the figure 2 the fourth requirement.
[0095] In this case, the specific content of the TFT rule selected by the PGW in step S302 is:
[0096] The destination port is port 0.
[0097] That is, on the default bearer, the service flows that do not meet this condition are filtered.
