Embodiment 1
[0061] 1. The rules 1 and 2 of the original TFT installed by PCRF include the following content:
[0062] TFT1 of Rule 1: Content 1 / Downstream; Priority 1;
[0063] TFT2 of rule 2: content 1 / uplink; priority 2;
[0064] Priority 1 is higher than priority 2.
[0065] At this time, the create bearer request message carries two TFTs, namely TFT1 and TFT2.
[0066] 2. PCRF updates TFT rule 1 to include the following content (rule 2 remains unchanged):
[0067] TFT3 of rule 1: content 1 / downstream;
[0068] TFT4 of rule 1: content 2 / downstream;
[0069] The priority is priority 3, and priority 3 is higher than priority 2.
[0070] In Embodiment 1, compared with the old rule, the content of TFT3 of rule 1 is the same as that of TFT1 of old rule 1, and the content of TFT4 of new rule 1 is new, and priority 1 becomes priority 3. However, priority 3 is still higher priority than 2. At this time, there is no need to update the content of TFT3 in the new rule 1. Although the prior...
Embodiment 2
[0072] 1. The rules 1 and 2 of the original TFT installed by PCRF include the following content:
[0073] TFT1 of Rule 1: Content 1 / Downstream; Priority 1;
[0074] TFT2 of rule 2: content 1 / uplink; priority 2;
[0075] Priority 1 is higher than priority 2.
[0076] At this time, the create bearer request message carries two TFTs, namely TFT1 and TFT2.
[0077] 2. PCRF updates TFT rule 1 to include the following content (rule 2 remains unchanged):
[0078] TFT3 of rule 1: content 1 / downstream;
[0079] TFT4 of rule 1: content 2 / downstream;
[0080] The priority is priority 3, and priority 3 is lower than priority 2.
[0081] The difference between example 2 and example 1 is that the priority in new rule 1 is lower than priority 2. Although the contents of TFT3 and TFT1 are the same, the levels of rule 1 and rule 2 have changed, and the priority of TFT1 needs to be replaced. As the priority of TFT3, trigger an update bearer request process of replace TFT, and then trigger...
Embodiment 3
[0083] 1. The rules 1 and 2 of the original TFT installed by PCRF include the following content:
[0084] TFT1 of Rule 1: Content 1 / Downstream; Priority 1;
[0085] TFT2 of rule 2: content 1 / uplink; priority 2;
[0086] Priority 1 is higher than priority 2.
[0087] At this time, the create bearer request message carries two TFTs, namely TFT1 and TFT2.
[0088] 2. PCRF updates TFT rule 1 to include the following content (rule 2 remains unchanged):
[0089] TFT3 of rule 1: content 1 / downstream;
[0090] TFT4 of rule 1: content 2 / downstream;
[0091] The priority is priority 3, and priority 3 is equal to priority 2.
[0092] The difference in example 3 is: the priority in the new rule 1 is equal to the priority 2. At this time, the priority of TFT3 and TFT1 is reasonable, and the content of TFT3 and TFT1 is the same, so there is no need to trigger on TFT3 To update the bearer, you only need to trigger the update bearerrequest process of add TFT once for TFT4.
[0093] The...
