IP (internet protocol) address allocation method and device

Abstract

The invention discloses an IP (internet protocol) address allocation method and an address allocation device, which are used for reducing business surface processing load during IP address allocation for an MUE (multiple user equipment) terminal user. The method comprises the following steps that a GGSN (gateway general packet radio service support node) receives PDP (packet data protocol) creation context request information, wherein the information comprises a user identification corresponding to the current user; the GGSN judges the terminal type of the current user attribution according to the user identification, and the current user attribution terminal is determined; when the current user attribution terminal type is the MUE type, whether an IP address is allocated to the user with the same terminal as the current user or not is judged; when the IP address is allocated to the user with the same terminal as the current user, the GGSN inquires the IP address allocated to the user with the same terminal as the current user and determines that the IP address is the current IP address; and the GGSN allocates the determined IP address of the current user to the current user requesting to access the network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Internet Protocol (IP, Internet Protocol) address allocation method and device. Background technique [0002] In a 3G network, a packet data protocol (Packet Data Protocol, PDP) address is used to provide services for user equipment (User Equipment, UE) to correctly perform packet data services. The GGSN allocates a PDP address for the user equipment through the PDP context activation process. The PDP address generally adopts the IP address format, so the IP address mentioned in this article is also the PDP address. [0003] An existing terminal may have one single-carrier data card or multiple independent single-carrier data cards (that is, multiple UE chips) bundled at the same time. A terminal with a single-carrier data card is an ordinary terminal, and a terminal with multiple independent single-carrier data cards is a multi-user terminal. For a multiple user term...

AI Technical Summary

Problems solved by technology

[0010] 1. The replacement of IP addresses by RNC increases the service processing delay, affects user experience, increases the service processing load of RNC equipment, and reduces the performance of RNC equipment

[0011] 2. Each UE in the terminal of the MUE type will be assigned an IP address, resulting in a waste of IP address resources on the network side

[0013] Therefore, the prior art method for allocating IP addresses to end users of the MUE type increases the service processing delay, increases the processing load of the RNC, and wastes IP address resources
