METHOD AND SYSTEM FOR SETTING UP A BEARER
First Claim
Patent Images
1. A method for setting up a bearer, comprising:
- obtaining, by a packet data network gateway (PGW), first quality of service (QoS) information and a first bearer identifier (ID), and setting up a bearer between the PGW and a radio access network (RAN) according to the first QoS information; and
setting up, by the RAN, a radio bearer (RB) between the RAN and a user equipment (UE) according to second QoS information, wherein the RB is associated with a second bearer ID;
the second QoS information is associated with the first QoS information; and
the second bearer ID is associated with the first bearer ID;
wherein the setting up a bearer between the PGW and a radio access network (RAN) according to the first QoS information comprises;
setting up, by the PGW, a first bearer between the PGW and a serving gateway (SGW) according to the first QoS information, wherein the first bearer is associated with the first bearer ID;
setting up, by the SGW, a second bearer between a serving general packet radio service support node (SGSN) and the SGW according to the first QoS information, wherein the second bearer is associated with the first bearer ID; and
setting up, by the SGSN, a third bearer between the SGSN and the RAN according to the second QoS information, wherein the third bearer is associated with 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.
