Problems solved by technology

[0015] 1. In the roaming scenario, the SGSN user plane function of the visited network needs to be used;
[0016] 2. In some cases, for users who realize the customized application (Customized Applications for Mobile network Enhanced Logic, CAMEL) service on the SGSN, the SGSN needs to obtain it from the Home Location Register (HLR) User's CAMEL subscription information, but SGSN cannot collect user traffic in One Tunnel mode;
[0017] 3. In some cases, the One Tunnel function cannot be used when the SGSN is activated for lawful interception and the SGSN needs to monitor Communication Content (CC) information.
In the era of mobile broadband, for Internet services with low tariffs, the resources of traditional network elements RNC, SGSN, and GGSN still need to be consumed, and the capacity bottleneck problem of these network elements has not been solved

Embodiment 1

[0035] Embodiment 1 of the present invention provides a communication network and an application method thereof. Such as image 3 As shown, the communication network includes NodeB, integrated service gateway, SGSN, fixed broadband bearer network and PDN. The NodeB is connected to the integrated service gateway through a TDM backhaul, one end of the fixed broadband bearer network is connected to the PDN through an IP backbone network, and the other end is connected to the NodeB. The integrated service gateway integrates the RNC and the GGSN, that is, integrates the RNC and the GGSN belonging to the service convergence gateway into one integrated service gateway, and the integrated service gateway includes an RNC functional module and a GGSN functional module. The integrated service gateway provided by this embodiment has the following advantages:

[0036] 1. It has no impact on massive Node Bs and does not affect the cost structure of Node Bs;

[0037] 2. Does not change th...

Embodiment 2

[0042] Such as Figure 4 As shown, after the integrated service gateway is started, the BOSS sends the PS service branching strategy to the integrated service gateway (401) through the management plane channel. The branching strategy, for example, can be based on APN (such as Internet service), user IMSI , Device IMEI (for example, only shunt USB), location Cell or SAI formulation. When the user PDP is activated, the integrated service gateway determines whether NodeB branching is required according to the pre-configured branching strategy. If NodeB branching is required, it interacts with NodeB and controls NodeB to perform branching (402); Path transfer (403); NodeB reports user data traffic to the integrated service gateway (404); the integrated service gateway generates a bill to the CG (405).

Embodiment 3

[0044] Such as Figure 5 As shown, when the user activates the PDP, the integrated service gateway interacts with the policy server, and the policy server decides whether the PDP activation is branched from the NodeB (501); if the NodeB branch is required, interact with the NodeB and control the NodeB to perform the branch ( 502); the user plane data is transmitted through the split path (503); the NodeB reports the user data flow to the integrated service gateway (504); the integrated service gateway generates a bill to the CG (505).

[0045] In the embodiment provided by the present invention, through the Gi interface of the integrated service gateway, the shared data network is directly connected to the shared data network, which saves the cost of the SGSN / GGSN. The transmission efficiency of mobile packet data; through the combination of 2-layer flat architecture (Node B-integrated service gateway) and 1-layer flat architecture, the performance and efficiency of IP data tran...

Abstract

The embodiment of the present invention discloses a communication network and a communication method, including an integrated service gateway, which is used for the user to interact with the policy server when the packet data protocol PDP is activated, and the policy server determines whether the current PDP activation is branched from the base station ; The policy server is used to determine whether this PDP activation is to be branched from the base station; if the policy server decides that it needs to be branched from the base station, the integrated service gateway is also used to interact with the base station to control the base station to perform branching, according to The user data flow reported by the base station generates a bill and sends it to the CG; the base station is used to directly access the user plane data to the PDN through the split fixed broadband bearer network, and report the user data flow to the integrated service gateway. The embodiments of the present invention can improve the transmission efficiency of PS services.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication network and a communication method. Background technique [0002] With the development of communication technology, the urgency of operators to develop Internet services is getting stronger and stronger. However, because the Wideband Code Division Multiple Access (WCDMA) packet network architecture basically inherits the general packet wireless service ( General Packet Radio Service, GPRS), so that the cost per MB of data cannot be reduced quickly even after the evolution of High-Speed ​​Packet Access (HSPA) air interface. [0003] The 3GPP R7 version proposes a One tunnel packet network architecture solution, such as figure 1 As shown, including network elements: [0004] Node B (101); [0005] Mobile Iub interface transmission network (Mobile backhaul) (102); [0006] Radio Network Controller (RNC) (103); [0007] Serving GPRS Support Node (Se...
