Embodiment 1

[0034] In the embodiment, a solution for implementing flow-level IP data offloading in a 3G network is provided. see figure 1 As shown, it is a flow chart of an embodiment of a method for realizing business data stream distribution in the present invention, including the following steps:

[0035] Step 101: When establishing or modifying the IP connection to access the network IP-CAN bearer, the mobile network gateway obtains the access type of each service data flow, wherein the access type includes split access and non-distributed access;

[0036] Among them, IP-CAN (IP-Connectivity Access Network Bearer, IP connection access network) is a collection of network entities and interfaces that realize the connection between UE and IMS (IP Multimedia Subsystem, IP Multimedia System) entities through IP. Typical An example is GPRS (General Packet Radio Service, General Packet Radio Service). The term is usually used in the cellular context to refer to 3GPP access networks such as...

Embodiment 2

[0054] In the EPS network architecture of this embodiment, the offload strategy is obtained from the PCRF by the PGW (PDN GateWay, packet data network gateway), and the offload strategy indicates the access types of various service data flows, and the access type includes offload access And non-distribution access, after the PGW obtains the access types of various service data flows according to the distribution policy, and then in the process of establishing the bearer, it indicates to the base station the access type of the service data flow transmitted on a certain bearer. see figure 2 , which is a flow chart of another embodiment of a method for realizing business data stream distribution in the present invention, including the following steps:

[0055] Step 201: The PGW learns the access type of each service data flow according to the offload strategy, and when it is determined that the access type of the service data flow transmitted on any IP-CAN bearer is offload acce...

Embodiment 3

[0079] Taking the terminal stationed in a new cell as an example, and each base station in the system has different offloading capabilities (some base stations can realize data offloading, and some base stations cannot realize data offloading) as an example, the whole The process of data shunting. Wherein, the PGW obtains the distribution policy from the PCRF. see image 3 , which is a signaling flow chart of an embodiment of a method for realizing service data flow offloading in the present invention, and specifically includes the following steps:

[0080] Step 301: the terminal sends an attach request message to the current base station;

[0081] Step 302: the current base station sends an attach request message to the MME;

[0082] Step 303: MME sends a session creation request message to SGW;

[0083] Preferably, the MME can know whether the current base station has the offload capability according to the local configuration or the information on whether each base stat...

Abstract

A method, system and related device for implementing service data stream offload are disclosed. The offload method includes: when IP-Connectivity Access Network (IP-CAN) bearers are established or modified, a mobile network management entity receives a bearer massage including an offload flag from a mobile network gateway, which obtains the access type of each service data stream, wherein the access types include offload access and non-offload access; when the access type of the service data stream transmitted on any IP-CAN bearer is determined to be the offload access according to the access type of each service data stream, the offload flag is used for indicating that the access type of the service data stream transmitted on the bearer is the offload access; the mobile network management entity transmits an bearer message including the offload flag to a base station so that the base station can implement offload for service data streams transmitted on the bearer according to the indication of the offload flag. An IP data stream offload solution based on stream level can be provided according to embodiments of the present invention.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and related device for realizing business data stream distribution. Background technique [0002] Local IP Access (LIPA) technology and IP data offload (Selected IP Traffic Offload, SIPTO) technology were originally proposed based on the Home Base Station (Home enhanced NodeB, HeNB) network, which means that the user's business data flow directly Access to the packet data network from HeNB does not go through the core network of the operator. Compared with the core network of the operator, since this part of the service data flow is directly offloaded from the HeNB, the load on the core network and transmission costs. [0003] With the development of wireless access technology, data transmission is transmitted at a higher rate, and the increase in the number of users and the increase in user data transmission rate have put forward higher req...
