IP address allocation method and device, equipment and medium

Abstract

The invention relates to an IP address allocation method and device, equipment and a medium. The method comprises the following steps: receiving a session establishment request sent by first user equipment; the session establishment request comprises subscription information of the first user equipment; judging whether the subscription information contains a static address or not; if the first user equipment contains the static address, allocating the static address to the first user equipment under the condition that the static address belongs to a pre-planned address range; if the first user equipment does not contain the static address, selecting a target address attribute according to the session establishment request or subscription information, and performing dynamic address allocation on the first user equipment based on the target address attribute and a first address pool; wherein the first address pool is a pre-configured address pool matched with the target address attribute. According to the invention, the signaling overhead can be reduced, and the address allocation efficiency and stability can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to an IP address allocation method, device, equipment and medium. Background technique [0002] In the field of mobile communication technology, the network architecture of 5G wireless communication system mainly includes: user equipment (UE, User Equipment), access network (NG-RAN, Next Generation Radio Access Network) and 5G core network (5GC, 5G Core Network). [0003] The IP (Internet Protocol, Internet Protocol) address of the user equipment is allocated by the 5GC during the session establishment process. At present, most address allocation schemes in 5G systems rely on multiple network element resources such as DHCP (Dynamic Host Configuration Protocol), AF (Application Function, application function) and UPF (User plane Function, user plane function) for address allocation. , the core of which is to obtain addresses through signaling interactions w...

Problems solved by technology

At present, most address allocation schemes in 5G systems rely on multiple network element resources such as DHCP (Dynamic Host Configuration Protocol), AF (Application Function, application function) and UPF (User plane Function, user plane function) for address allocation. , its core is to obtain addresses through signaling interaction with the above-mentioned multiple network elements, and assign them to corresponding user equipment; however, this solution has the problems of heavily relying on network element resources and high signaling interaction overhead

Or, there are some solutions suitable for 4G systems. However, 5G system technology has changed greatly compared with 4G system technology, and the address allocation scheme suitable for 4G systems has very large limitations in 5G systems.
