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.
Claims19
A communication method, comprising:
- receiving, by a serving general packet radio service support node (SGSN), a packet data protocol (PDP) context activation request from a user equipment;
- sending, by the SGSN, a second bearer setup request to a serving gateway (SGW);
- sending, by the SGW, a first bearer setup request to a packet data network gateway (PGW);
- receiving, by the SGW, a first bearer setup response from the PGW;
- receiving, by the SGSN, a second bearer setup response from the SGW;
- sending, by the SGSN, a radio access bearer (RAB) assignment request to a radio access network (RAN);
- setting up, by the RAN, a radio bearer with the user equipment;
- receiving, by the SGSN, an RAB assignment response from the RAN;
- and
- returning, by the SGSN, a PDP context activation response to the user equipment.
A communication system, comprising:
- a serving general packet radio service support node (SGSN), a serving gateway (SGW) and a packet data network gateway (PGW);
- wherein:
- the SGSN is configured to receive a packet data protocol (PDP) context activation request from a user equipment and to send a second bearer setup request to the SGW;
- the SGW is configured to send a first bearer setup request to the PGW;
- the PGW is configured to send a first bearer setup response to the SGW;
- the SGW is further configured to return a second bearer setup response;
- the SGSN is further configured to send a radio access bearer (RAB) assignment request to a radio access network (RAN) for the RAN to set up a radio bearer with the user equipment;
- and
- the SGSN is further configured to receive an RAB assignment response from the RAN and to return a PDP context activation response to the user equipment.
