METHOD, APPARATUS AND SYSTEM FOR SERVICE ESTABLISHMENT FOR MULTI-MODE USER EQUIPMENT

摘要

The embodiments of the present invention provide a method, an apparatus and a system for service establishment for a multi-mode user equipment. In an embodiments of the present invention, a centralized control entity (Controller) may obtain the base station information of the respective base stations in the multi-RAT network in real time and select proper RAT base station information in accordance with service demand of the user equipment, so as to initiate bearer establishment for the service. Compared with the prior art which only aims at a particular service and handover can only be performed in particular RAT networks, the present solution does not has particular limitation on a service, and moreover, a proper RAT network may be selected from multiple RAT networks more flexibly for each service without increasing power consumption of the user equipment.

主权项

1. A method for service establishment for a multi-mode user equipment, comprising:
receiving a service request sent by a first multi-mode user equipment, wherein the service request carries an identity of the first multi-mode user equipment, a service type and information about quality of service required by a service; obtaining base station information of respective base stations in a multi-radio access technology network, wherein the base station information comprises information on load of a base station and information on quality of service of a service that the base station can provide; determining target base station information according to the service request and the base station information; and performing one of: initiating bearer establishment for the service according to the target base station information, and sending the target base station information to the first multi-mode user equipment, such that the first multi-mode user equipment initiates bearer establishment for the service according to the target base station information.
