Method and system for setting up a bearer
First Claim
1. A serving general packet radio service support node (SGSN), comprising:
- a QoS information obtaining unit, adapted to obtain first QoS information;
a downlink bearer resource (DBR) allocating unit, adapted to allocate a second DBR for a second bearer according to the first QoS information;
a DBR information sending unit, adapted to send the first QoS information and information about the second DBR;
an uplink bearer resource (UBR) information receiving unit, adapted to receive the first QoS information, information about a second UBR, and a first bearer ID;
a UBR information storing unit, adapted to store the first QoS information, the information about the second UBR, and the first bearer ID;
a UBR allocating unit, adapted to allocate a third UBR for the second bearer according to second QoS information associated with the first QoS information;
a UBR information sending unit, adapted to send the second QoS information and information about the third UBR;
a DBR information receiving unit, adapted to receive the second QoS information, information about a third DBR, and a second bearer ID associated with the first bearer ID; and
a DBR information storing unit, adapted to store the second QoS information, the information about the third DBR, and the second bearer ID.

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. According to the technical solution of the present invention, when the UE is connected to a serving gateway (SGW) through a serving general packet radio service support node (SGSN), the SGSN and the SGW set up a bearer between the UE and the PGW. Thus, resources of each network entity in a network are fully utilized.
