Problems solved by technology

[0007] It can be seen that through the existing process, the MS can only obtain one of IPv4 or IPv6 addresses each time, and usually, the MS cannot predict in advance whether the application service it wants to access is an IPv4 network or an IPv6 network, so when the MS allocates After obtaining the IPv4 address, if the accessed service is IPv6, there will be problems with direct intercommunication, and vice versa
Therefore, the application of different networks requires frequent switching between different networks, which is not only cumbersome but also inefficient.
The current MS cannot obtain IPv4 and IPv6 addresses at the same time, and the dual-stack capability of the dual-stack MS has not been fully utilized

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0040] An embodiment of the present invention provides a method for obtaining an address, the process of which is as follows figure 2 shown, including:

[0041] Step 201: The MS initiates two activation PDP context requests to the network side at the same time through the preset dual-stack APN, one of which specifies the PDP type as IPv4, and the other specifies the PDP type as IPv6;

[0042] When the MS accesses the packet domain service, it must first obtain an IP address, and the MS often cannot predetermine the IP type (IPv4 or IPv6) of the accessed service when accessing the service, so the MS does not know what type it should apply to the GGSN for IP address. In the prior art, it is usually to specify the IP address type that the APN can obtain...

Abstract

The invention discloses a method for accessing addresses, comprising the following steps: a mobile terminal (MS) simultaneously launches two activation packet data protocol (PDP) context requests to a network side through a preset dual-stack access point name (APN) in advance, wherein the PDP type specified in one request is IPv4, and the PDP type specified in the other request is IPv6; the network side respectively responds to the two activation PDP context requests to finish the address allocation flows corresponding to the requests; and the MS receives the responses of the network side to the requests to access the an IPv4 address and an IPv6 address allocated by the network side. The invention also provides the MS and an application method thereof. According to the method and system for accessing addresses in the embodiment of the invention, two activation PDP context requests are simultaneously launched to the network side, and the network side respectively responds to the two activation PDP context requests to finish the address allocation flows, thereby simultaneously accessing the IPv4 address and the IPv6 address.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for address acquisition, and also to a mobile terminal and its application method. Background technique [0002] With the rapid development of the Internet Protocol (Internet Protocol, IP) version number v4 network, the allocation of IP address space, Quality of Service (QoS) and security issues have gradually become important factors affecting network development. In order to solve the above problems, the Internet Engineering Task Force (IETF) further proposed the RFC1883 standard protocol document, which was further updated and improved, and finally formed a complete protocol system RFC2460. The network defined by this protocol system is usually called IPv6 network. IPv6 fundamentally solves the problem of exhaustion of IP addresses, and optimizes the protocol in many aspects such as address classification, header format, security, QoS, plug and pl...
