Embodiment 1

[0051] A method for processing a downlink signaling message process disclosed in an embodiment of the present invention is introduced in detail.

[0052] refer to figure 2 , shows a flow chart of a downlink signaling message process processing method disclosed in Embodiment 1 of the present invention.

[0053] In step S11, the packet data gateway sends a downlink signaling request message to the service gateway after receiving the IP connection access network session modification request message sent by the policy and charging rule function network element.

[0054] The PCRF network element sends an IP-CAN session modification request message to the PGW, and carries the PCC rule to the above-mentioned PGW, and the above-mentioned PGW saves the above-mentioned PCC rule and sends a downlink signaling request message to the SGW, and sets the state machine to wait for the above-mentioned SGW to send a downlink signaling response information.

[0055] Step S12, after the serving...

Embodiment 2

[0063] A method for processing a downlink signaling message process disclosed in an embodiment of the present invention is introduced in detail.

[0064] refer to image 3 , shows a flow chart of a downlink signaling message process processing method disclosed in Embodiment 2 of the present invention.

[0065] The downlink signaling request message may specifically include:

[0066] Create, update or delete dedicated bearer request messages.

[0067] A dedicated bearer is a type of bearer. The bearer refers to providing a quality of service (Qualirt of Service, QoS) transmission guarantee with certain characteristics between the UE and the packet data network (Packet Data Network, PDN), and is divided into a default bearer and a dedicated bearer.

[0068] 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 requirem...

Embodiment 3

[0095] A method for processing a downlink signaling message process disclosed in an embodiment of the present invention is introduced in detail.

[0096] refer to Figure 4 , which shows a schematic diagram of a downlink signaling message flow processing method disclosed in Embodiment 3 of the present invention.

[0097] In step S31, the PCRF network element initiates an IP-CAN session mod request to the PGW.

[0098] Step S32, the above-mentioned PGW sends a Creat Bearer Req message to the SGW according to the above-mentioned IP-CAN session mod request.

[0099] In step S33, the SGW sends a Creat Bearer Rsp message carrying UE location information to the PGW.

[0100] Before the above step S33, the above SGW may also receive a Modify Bearer Req message sent by the MME or SGSN, and respond to a Modify Bearer Rsp message to the MME or SGSN.

[0101] In step S34, the PGW responds to the PCRF network element with the IP-CAN session mod request according to the Creat Bearer Rsp...

Abstract

The invention discloses a downlink signaling message flow processing method and a system, so that the problems that in the prior art, packet gate way (PGW) is large in flow processing difficulty, signaling interaction between network elements is frequent, and information processing flows are complex are solved. The method comprises the following steps: after the PGW receives internet protocol (IP) connecting visit network conversation modification request messages sent by a policy and charging rules function (PCRF) network element, and sends downlink signaling request messages to a signal gate way (SGW); after the SGW receives the downlink signaling request messages, and when user experience (UE) position information changes, the SGW stores the current UE position information and sends downlink signaling response massages carrying with the current UE position information to the PGW; after the PGW receives the downlink signaling response massages, the PGW sends IP connecting visit network conversation modification response messages not carrying with the current UE position information to the PCRF network element; and the PGW sends the current UE position information to the PCRF network element. According to the downlink signaling message flow processing method and the system, PGW processing difficulty is reduced, and downlink signaling massage flow processing is simplified.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and system for processing a downlink signaling message flow. Background technique [0002] In the 3GPP 23401 protocol, the service request process triggered by the network side is: the Serving Gateway (SGW) receives the downlink signaling request message sent by the Packet Data Network Gateway (PGW), such as creating a dedicated bearer request message or modify the dedicated bearer request message, etc., the SGW will notify the mobility management entity (Mobility Management Entity, MME) or GPRS serving support node (Serving GPRS Support Node, SGSN) to send a downlink signaling request to the user equipment (User Equipment, UE) information. If the UE is in the Evolved Packet System Connectivity Management (ECM) idle state, the MME or SGSN will trigger paging to the UE, and then the UE initiates a service request process to modify th...
