Abstract

Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

Claims

1. A method for setting up a bearer, the method comprising:

setting up, by a serving general packet radio service support node (SGSN), a bearer between the SGSN and a packet data network gateway (PGW) through a serving gateway (SGW) according to first quality of service (QoS) information, wherein the bearer between the SGSN and the PGW is associated with a first bearer ID; and

setting up, by the SGSN, a bearer between the SGSN and a radio access network (RAN) according to second QoS information which is mapped from the first QoS information according to a mapping relationship between the first Qos information and the second QoS information, wherein the bearer between the SGSN and the RAN is associated with a second bearer ID which is mapped from the first bearer ID according to a mapping relationship between the first bearer ID and the second bearer ID;

wherein the setting up, by the SGSN, the bearer between the SGSN and the RAN comprises;

sending, by the SGSN, a request message for a radio access bearer (RAB) assignment to the RAN for the RAN to set up a radio bear with a user equipment (UE),

receiving, by the SGSN, a response message for the RAB assignment from the RAN.

2. A serving general packet radio service support node (SGSN), comprising:

a first unit, configured to set up a bearer between the SGSN and a packet data network gateway (PGW) through a serving gateway (SGW) according to first quality of service (QoS) information, wherein the bearer between the SGSN and the PGW is associated with a first bearer ID; and

a second unit, configured to set up a bearer between the SGSN and a radio access network (RAN) according to second QoS information which is mapped from the first QoS information according to a mapping relationship between the first Qos information and the second QoS information, wherein the bearer between the SGSN and the RAN is associated with a second bearer ID which is mapped from the first bearer ID according to a mapping relationship between the first bearer ID and the second bearer ID,

wherein in a process of setting up the bearer between the SGSN and the RAN, the second unit is configured to send a request message for a radio access bearer (RAB) assignment to the RAN for the RAN to set up a radio bear with a user equipment (UE), and receive a response message for the RAB assignment from the RAN.

3. A communication network comprising:

a serving general packet radio service support node (SGSN) communicatively connected to a packet data network gateway (PGW), a serving gateway (SGW), and a radio access network (RAN),

wherein the SGSN is configured to;

set up a bearer between the SGSN and the PGW through the SGW according to first quality of service (QoS) information, wherein the bearer between the SGSN and the PGW is associated with a first bearer ID; and

set up a bearer between the SGSN and the RAN according to second QoS information which is mapped from the first QoS information according to a mapping relationship between the first Qos information and the second QoS information, wherein the bearer between the SGSN and the RAN is associated with a second bearer ID which is mapped from the first bearer ID according to a mapping relationship between the first bearer ID and the second bearer ID;

wherein in a process of setting up a bearer between the SGSN and the RAN, the SGSN is configured to send a request message for a radio access bearer (RAB) assignment to the RAN for the RAN to set up a radio bear with a user equipment (UE), and receive a response message for the RAB assignment from the RAN.
