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] conform to figure 2 The requirements of the first item in .
[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, the service flow that does not meet any of the conditions is filtered.
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] conform to figure 2 The requirements of the third item, which, while 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, but not ARP information, therefore, as long as the requirements of QCI information content are met, it is regarded as 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, the service flow that does not meet any of the conditions is filtered.
example 3
[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] conform to figure 2 The requirements of the fourth item.
[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 flow that does not meet this condition is filtered.

Abstract
The embodiment of the invention discloses a service filtering method and device based on a default bearer. By applying the technical scheme of the embodiment of the invention, a PGW (packet data network gateway) is used for configuring the corresponding TFT (traffic flow template) rules for the default bearer according to APN (access point name) information, and services on the default bearer are filtered according to the TFT rules, so that the corresponding service flows, such as the service flow of the services with the lower added value, can be filtered out according to the corresponding rules, the management, the control and the optimization of the services on the default bearer can be realized, an operator can perform the flexible management and the control on the services of different users, which are connected into a PDN (packet data network) and the controllability of the PGW to the network as a core network interface can be improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a service filtering method and equipment based on a default bearer. Background technique [0002] In the existing communication network, in order to provide certain characteristics of QoS (Quality of Service, quality of service) transmission between UE (User Equipment, user equipment, that is, terminal equipment) and PDN (Packet Data Network, packet data network) Guaranteed bearers fall into two categories: default bearers and dedicated bearers. [0003] Among them, the dedicated bearer is established on the basis of the establishment of the PDN link, and is established to provide a specific QoS transmission requirement (the default bearer cannot meet it). Generally, the QoS requirements for dedicated bearers are higher than those for default bearers. The dedicated bearer is associated with a UL (Uplink, uplink) TFT (Traffic Flow Template, service flow template) in the UE...
