Problems solved by technology

However, in a multi-access system, multiple bearers of the UE will have different RAT types. The current gateway cannot know the RAT type of the bearer during the bearer management process such as establishment and modification of the bearer, and thus cannot accurately identify the UE. Differential billing, inaccurate billing

Embodiment 1

[0056] This embodiment is based on figure 1 In the system architecture shown, the SGW is used as an anchor point to implement a bearer management method supporting multiple access, such as Figure 5 As shown, the method includes the following steps:

[0057] Step 501, the PGW sends a bearer establishment request message to the SGW, and the message carries the PGW's uplink user plane IP address and a tunnel endpoint identifier (TEID, Tunnel Endpoint Identifier);

[0058] Step 502, the SGW receives the bearer establishment request message, and determines that the RAT type of the bearer establishment is the LTE system according to the local policy, then the SGW sends the bearer establishment request message to the MME, and carries the PGW's uplink user plane IP address and TEID, and the SGW's uplink IP address. User plane IP address and TEID;

[0059] Step 503, the MME receives the bearer establishment request message of the SGW, establishes the bearer and distributes the EPS b...

Embodiment 2

[0071] This embodiment is based on figure 1 In the system architecture shown, the SGW is used as an anchor point to implement a bearer management method supporting multiple access, such as Figure 6 As shown, the method includes the following steps:

[0072] Step 601, the PGW sends a bearer update request to the SGW;

[0073] Step 602, the SGW receives the bearer update request, determines the RAT type of the bearer update to be the LTE system according to the local policy, and is about to migrate the bearer from the UTRAN system or the GERAN system to the LTE system, then the SGW sends a bearer establishment request message to the MME, and the message carries PGW's uplink user plane IP address and TEID, SGW's uplink user plane IP address and TEID;

[0074] Step 603, MME receives the bearer establishment request message from the SGW, establishes the bearer and allocates EBI, MME establishes a session management request message, which carries EBI, bearer QoS, MME and sends a ...

Embodiment 3

[0093] This embodiment is based on figure 2 In the system architecture shown, the RNC is used as an anchor point to implement a bearer management method supporting multiple access, such as Figure 7 As shown, the method includes the following steps:

[0094] Step 701, the PGW sends a bearer establishment request message to the SGW, and the message carries the uplink user plane IP address and TEID of the PGW;

[0095]Step 702, the SGW receives the bearer establishment request message, and sends a bearer establishment request message to the SGSN, the message carrying the PGW's uplink user plane IP address and TEID, and the SGW's uplink user plane IP address and TEID;

[0096] Step 703, after receiving the bearer establishment request message, the SGSN sends a RAB assignment request message to the RNC, and the message carries the uplink user plane IP address and TEID of the SGSN;

[0097] Step 704, after the RNC receives the bearer establishment request message from the SGSN, ...

Abstract

The invention discloses a bearer management method supporting multiple access. During the bearer management process, the anchor point determines the radio access technology (RAT) type for bearer establishment or update, and during the bearer establishment or update process, the RAT The type notifies the core network gateway; the invention also discloses a bearer management system supporting multiple accesses. Through the solution of the present invention, the core network gateway can know the RAT type of the bearer, and can perform accurate differential charging according to the RAT type, avoiding the problem of inaccurate charging.

Description

technical field [0001] The invention relates to bearer management technology in the field of mobile communication, in particular to a bearer management method and system supporting multiple access. Background technique [0002] In the field of mobile communication, Evolved Packet System (EPS, Evolved Packet System) and General Packet Radio Service (GPRS, General Packet Radio Service) networks are gradually developing. The EPS mainly includes two parts: Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) and Evolved Packet Core Network (EPC, Evolved Packet Core). The EPC of the system can support user access from a GSM EDGE radio access network (GERAN, GSM EDGE radio access network) and a universal terrestrial radio access network (UTRAN, Universal Terrestrial Radio Access Network). [0003] In the EPC packet core network, it includes a home subscriber data server (HSS, Home Subscriber Server), a mobility managemen...
