Method and equipment for accessing mobile communication system

Abstract

The invention provides a method for accessing a mobile communication system. The method includes steps of enabling 3GPP UE (3rd generation partnership project user equipment) connected with non-3GPP user equipment to initiate an attach request containing a specified APN (access point name) value; establishing a carrying link between the 3GPP UE and a PGW (packet data gateway) after authentication is successfully carried out and transmitting uplink and downlink data of Ethernet data packets of the non-3GPP user equipment via the carrying link. The method has the advantages that relevant 3GPP protocols are extended, so that business for enabling non-3GPP users to access the mobile communication system via a 3GPP network can be supported, a network arrangement scheme of operators can be flexible and convenient, user groups of the operators can be expanded, the non-3GPP users and LTE (long term evolution) users can be managed by the operators in a unified manner, and billing and refined business service can be provided for the non-3GPP users and the LTE users by the operators.

Description

technical field [0001] The present invention relates to the field of mobile communication, specifically, the present invention relates to a method and equipment for accessing a mobile communication system. Background technique [0002] Modern mobile communication tends to provide high-speed multimedia services more and more, and 3G technology has become the main research field of modern mobile communication. The 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is committed to using the LTE (Long Term Evolution, Long Term Evolution) system as the evolution of the 3G system. [0003] The existing LTE network is used to bear the IP service flow of LTE UE, and its network reference model can be found in figure 2 , mainly involving network elements including: [0004] 1) LTE user terminal (LTE UE): a mobile device capable of transmitting and receiving wireless signals, baseband processing and high-level application operation, responsible for interco...

AI Technical Summary

Problems solved by technology

[0022] 1) The LTE network only provides an IP-based network path for non-3GPP users, and non-3GPP user data cannot be transparently transmitted to the existing broadband access network through the LTE network;

[0023] 2) When using the LTE network to build an enterprise-level IP virtual network, the VLAN information of the second layer cannot be transmitted;

[0024] 3) The LTE network cannot distinguish the QoS requirements of the accessed non-3GPP user service flow, and cannot perform QoS management;

[0025] 4) When non-3GPP hotspots are accessed through LTE terminals, LTE operators cannot effectively manage non-3GPP users
