Problems solved by technology

[0027] The main purpose of the present invention is to provide a service data flow processing method and device to at least solve the problem that the service data flow without admission control in the above-mentioned related technologies will seize the resources of other service data flows that have undergone admission control, resulting in the current FMC strategy The problem of failure of the control mechanism

Embodiment 1

[0080] Figure 5 It is a flow chart of attachment in the roaming scenario of home routing in which the UE accesses the 3GPP core network through the H(e)NB in ​​the present invention. Figure 5 The GTP protocol is adopted between the S-GW and the P-GW. The home network supports policy-controlled interworking with the fixed broadband access network.

[0081] Step S502: the HeNB is powered on and connected to the fixed broadband access network. The fixed broadband access network allocates a local IP address for the HeNB. The HeNB and the SeGW establish an IPSec tunnel. During this process, it is detected that there is a Network Address Translation (Network Address Translation, NAT) between the HeNB and the SeGW. If it exists, the SeGW will pass through the local IP address of the HeNB after the NAT and the source user datagram protocol. (User Datagram Protocol, UDP for short) port number is sent to the HeNB. The HeNB interacts with the HeMS to obtain configuration informatio...

[0112] Figure 6 It is a flow chart of a PDN connection request in a roaming scenario of a home route in which a UE accesses a 3GPP core network through an H(e)NB in ​​the present invention. Figure 6 The GTP protocol is adopted between the S-GW and the P-GW. The home network supports policy-controlled interworking with the fixed broadband access network.

[0113] Step S602: UE sends a PDN connection request message to MME, and H(e)NB adds H(e)NB local IP address and optional UPD port number to the message.

[0114] Step S604: The MME sends a session creation request message to the S-GW, carrying the user identifier, PDN identifier, HeNB local IP address, and optionally, the source UDP port number (if NAT is detected);

[0115] Step S606: The S-GW creates a session request message to the P-GW, carrying the user identifier, the PDN label, the network label of the visited network where the S-GW is located, the local IP address of the HeNB, and optionally, the source UDP port n...

Abstract

The invention discloses a business data stream processing method and device. The business data stream processing method comprises the following steps of: judging whether admission control is performed on a business data stream or not by a fixed broadband access network; and performing different DSCP (differentiated services code point) marking on an IP (internet protocol) packet of the business data stream according to the judgment result. By adopting the business data stream processing method and device disclosed by the invention, the problem that a whole FMC (fixed mobile convergence) strategy control mechanism fails due to the situation that the business data stream of UE (user equipment) after admission control can seize resources of other business data streams after admission control in the prior art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing service data streams. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) consists of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network for short). -UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW for short), home user server (Home Subscriber Server, HSS for short). figure 1 It is a schematic diagram of an architecture of a home base station (Home evolved NodeB, HeNB for short) accessing an EPS in a non-roaming scenario according to the related art. Combine below figure 1 The structure of the EPS will be described. [0003] exist figure 1 Among them, MME is ...
