Embodiment Construction
[0060] method embodiment
[0061] In this embodiment, a method for notifying a user equipment access protocol is provided, which is applied to a system including a policy control and charging rule functional entity, a packet data network gateway, an access gateway, and a home user server / authentication, authorization and charging server Evolved packet system.
[0062] Such as Figure 4 As shown, the method for notifying the user equipment access protocol according to this embodiment includes: step S402, when it is determined that the user equipment accesses the network through a specific protocol, the access gateway assigns a care-of address to the user equipment, and in the first session request A specific attribute-value pair is set in the message to represent the care-of address, and the first session request message is sent to the policy and charging rule functional entity; step S404, the packet data network gateway assigns a home address to the user equipment, and the us...

Abstract
The invention discloses a notification method of a user equipment access protocol. The method comprises the following steps: step S402: when user equipment accesses to a network by a specific protocol, an access gateway assigns a care-of address to the user equipment, a specific attribute value pair is set in a first session request message to represent the care-of address, and the first session request message is sent to a policy and charging rule function entity; step S404: a packet data network gateway assigns a home address to the user equipment, and the user equipment sends the care-of address and the home address to the packet data network gateway; and S406: the packet data network gateway sets a specific attribute value pair in the second session request message to represent the care-of address, and a preset attribute value pair represents the home address, and the session request message is sent to the policy and charging rule function entity. Additionally, the invention further discloses a notification system of the user equipment access protocol.
Description
technical field [0001] The present invention relates to the field of communications, and in particular, to a method and system for notifying user equipment access protocols. Background technique [0002] Such as figure 1 As shown, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) evolved packet system (Evolved Packet System, EPS) includes: evolved UTRAN (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), mobility management unit (Mobility Management Entity, MME), Serving Gateway (Serving Gateway, S-GW), Data Network Gateway (PacketData Network Gateway, PDN GW, that is, P-GW), Home Subscriber Server (Home Subscriber Server, HSS), 3GPP authentication authorization accounting A server (3GPP AAA server), a policy and charging rules function (Policy and Charging Rules Function, PCRF), and other supporting nodes. [0003] Among them, MME is responsible for mobility management, non-access stratum signaling processing, user mobility manag...
