Problems solved by technology

According to the current agreement, BNG cannot perform unified control and management of resources, and the PCRF that formulates policies, because there are different access devices and access scenarios, multiple PCRFs may exist at the same time (such as PCRF in the H(e)NB scenario) , the PCRF of WLAN-EPC-routed may not be the same), multiple PCRFs control the resources of this line, and there will be double calculation (that is, the same resource may be allocated to different devices at the same time), resulting in resource allocation errors
[0025] In view of the fact that fixed network gateways (such as BNG) in different scenarios of multiple access devices and multiple access modes in related technologies cannot perform unified control and management of resources, resource allocation errors are prone to occur when multiple PCRFs control line resources, No effective solution has been proposed so far

Embodiment 1

[0100] Figure 5 It is a flow chart of admission control according to preferred embodiment 1 of the present invention. It should be noted that in this embodiment 1, it is assumed that the identification information of PCRF+ has been pre-configured on the BNG, and PCRF+ does not need to pass through a third-party device DRA (Diameterroute Agent, Diameter routing agent). ) as a Proxy (proxy), for example, by configuring the IP address or FQDN of PCRF+ on the BNG.

[0101] Such as Figure 5 As shown, the process mainly includes the following steps:

[0102] Step S501: The BNG is triggered, and the trigger condition is that a terminal is connected to the corresponding fixed line, or a mobile terminal, or a fixed terminal, or the H(e)NB is powered on.

[0103] Step S502: The BNG initiates to the PCRF+ an establishment operation of a Gxd policy session (1) corresponding to the fixed network line, and establishes a Gxd session (1) with the PCRF+. The BNG stores the fixed network l...

Embodiment 2

[0122] Figure 6 It is the admission control flow chart according to the preferred embodiment 2 of the present invention. In this embodiment 2, it is assumed that the BNG does not necessarily have PCRF+ identification information pre-configured (to avoid exposing the network topology), and the BNG needs to use the third-party device DRA to find PCRF+ It can only be found by acting as a proxy. Of course, PCRF also needs to use DRA to find PCRF+.

[0123] Such as Figure 6 As shown, the process mainly includes the following steps:

[0124] Step S601: The BNG is triggered, and the trigger condition is that a terminal is connected to the corresponding fixed line, or a mobile terminal, or a fixed terminal, or the H(e)NB is powered on.

[0125] Step S602a: BNG initiates to PCRF+ a Gxd strategy session (1) establishment operation corresponding to the fixed network line, and the session request is first sent to the DRA in the PCRF domain, and the session request carries at least the...

Embodiment 3

[0145] Figure 7 It is a flow chart of admission control according to the third preferred embodiment of the present invention. In this third embodiment, it is assumed that the third-party device DRA has a redirection (redirect) function. Both BNG and PCRF need to use DRA when looking for PCRF+.

[0146] Such as Figure 7 As shown, the process mainly includes the following steps:

[0147] Step S701: The BNG is triggered, and the trigger condition is that a terminal is connected to the corresponding fixed line, or a mobile terminal, or a fixed terminal, or the H(e)NB is powered on.

[0148] Step S702a: BNG initiates to PCRF+ a Gxd policy session (1) establishment operation corresponding to the fixed network line, and the session request is first sent to the DRA in the PCRF domain, and the session request carries at least the line identifier of the fixed network.

[0149] The BNG stores the fixed network line ID, the IP address assigned by the BNG to the mobile terminal / fixed ...

Abstract

The invention discloses an admission control method and system. Wherein, the method includes: a first Policy and Charging Rules Function (PCRF) entity establishes a first policy session with a fixed network gateway; the second PCRF entity obtains the entity location information of the first PCRF entity through the fixed network gateway, and according to After the entity location information establishes an interworking policy session with the first PCRF entity, the first PCRF entity performs an admission control operation on the service. Through the present invention, the effect of enabling the fixed network gateway and PCRF to effectively control and manage line resources is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an admission control method and system. Background technique [0002] 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) EPS (Evolved Packet System, evolved packet system), please refer to figure 1 , figure 1 It is a schematic diagram of the overall network architecture of UE accessing from H(e)NB, WLAN-EPC-routed, WLAN-NSWO and fixed equipment under the same fixed network line according to the related technology. exist figure 1 In the network architecture diagram shown, there are 3GPP access network, that is, E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Mobile Communication System Terrestrial Radio Access Network), and MME (Mobility Management Entity, mobile management unit), S-GW (Serving Gateway, service gateway), P-GW or PDN GW (Packet Data Network Gateway, packet data network gateway), HSS (Home Subscriber Ser...
