Abstract

The invention discloses a method, a gateway, a PCRF network element and a system for dynamically assigning an IP address pool. The method includes: when receiving a network attachment request of a user terminal, sending an assignment request to a PCRF network element, wherein the assignment request includes user identification and user location information, so that the PCRF network element is based on the user identification and user location information. The user terminal allocates an IP address pool and returns the allocated IP address pool; allocates an IP address for the user terminal in the IP address pool allocated by the PCRF network element. The present invention performs dynamic authorization management on the PGW address pool through the PCRF network element, solves the problem that the address pool can only be allocated singlely according to the APN or IMSI number segment, and realizes dynamic address pool allocation to users based on strategies such as location.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for dynamically assigning an IP address pool, a gateway, a PCRF network element and a system. Background technique [0002] Ordinary users in any location (such as controlled and non-controlled areas) are assigned IP addresses by PGW (PDN GateWay, public data network gateway) according to ANP (access point) and IMSI (International Mobile Subscriber Identity) number segments, and PCRF Network elements (Policy and Charging Rules Function, policy and charging rule function) network elements do not participate in the allocation of IP addresses, so the network cannot allocate address pools according to the user's credit level, user location, and PGW status. Contents of the invention [0003] In view of the above technical problems, the present invention provides a method, gateway, PCRF network element and system for dynamically assigning an IP address pool, which solves ...
