Embodiment Construction

[0046] In order to solve the existing difficulties in assigning addresses to user equipment in the 3GPP long-term evolution system LTE / SAE system in the prior art, resulting in inconvenience in IP address management and even address conflicts, the present invention allocates addresses for UEs in the address space managed by IASA. An IP address, where the IP address is used in subsequent multiple service connections between the UE and different packet data networks (PDNs).

[0047] Further, in order to solve 3GPP LTE / SAE system and 3GPP UTRAN (Universal Mobile Telecommunications System Terrestrial Radio Access Network), 3GPP GERAN (Global System for Mobile Communications / Global System Evolved Enhanced Data Rate Radio Access Network) system, non- For the mobility between 3GPP IP access (non 3GPP IP Access) systems and WLAN (Wireless Local Area Network) 3GPP IP access systems, in the present invention, IASA is still in its own address space for UEs accessing these access systems ...

Abstract

The invention discloses a method of user equipment address distribution in 3GPP long term evolution system LTE/SAE, which can solve the problem of the user equipment address distribution, IP address management complexity and the address conflict in the prior technical proposal of 3GPP long term evolution system LTE/SAE system. In the method, the user equipment is distributed with IP address in the address space of self management by different anchor points access to system in the course of user equipment attached to LTE/SAE system and establishing basic bearing connection. The distributed IP address will be applied to the business connection of the user equipment and different packet data network in the future. The invention also discloses a method and a communication system of user utilization of packet data network business in long term evolution system.

Description

technical field [0001] The present invention relates to the long-term evolution system LTE / SAE (Long-Term Evolution / System Architecture Evolution) of the third generation partner 3GPP in the communication field and a method for allocating addresses for user equipment. Background technique [0002] Since the current long-term evolution (Long Term Evolution, LTE) / system architecture evolution (System Architecture Evolution, SAE) network system researched by the third-generation partner 3GPP is an all-IP-based packet data network, user equipment (User Equipment, UE) The business with the network needs to use the IP address to identify the destination address and source address of the data packet, so an IP address must be allocated to the UE. The Long Term Evolution LTE / SAE system is shown in Figure 1. According to the existing technology, the IPv4 address-based network and the IPv6-based network cannot interact directly with each other. In order to enable the UE to interact wit...
