释放IP地址的方法、装置、网络设备及系统
Abstract:
(EN)
The present application relates to the technical field of communications. Disclosed are a method and apparatus for releasing an IP address, a network device, and a system, for solving the problem of inaccuracy in a release time of an IP address. The method comprises: a first network device determines that a PDU session anchor needs to be repositioned from a first user plane functional entity, wherein the first user plane functional entity is a PDU session anchor of a first PDU session of a terminal; the first network device determines that a first IP address of the terminal is no longer used, wherein the first IP address is an IP address used in the first PDU session; and the first network device releases the first IP address.
(FR)
La présente invention se rapporte au domaine technique des communications. L'invention concerne un procédé et un appareil de libération d'une adresse IP, un dispositif de réseau, et un système, destinés à résoudre le problème du manque de précision dans un instant de libération d'une adresse IP. Le procédé comporte les étapes suivantes: un premier dispositif de réseau détermine qu'une ancre de session de PDU doit être repositionnée à partir d'une première entité fonctionnelle de plan d'utilisateur, la première entité fonctionnelle de plan d'utilisateur étant une ancre de session de PDU d'une première session de PDU d'un terminal; le premier dispositif de réseau détermine qu'une première adresse IP du terminal n'est plus utilisée, la première adresse IP étant une adresse IP utilisée dans la première session de PDU; et le premier dispositif de réseau libère la première adresse IP.
