Preprocessing method for distributing address and mobile performance management entity

Abstract

The invention discloses a method for preprocessing an allocated address, which comprises the following steps: the corresponding relation between an external data network accessed in an LBO area at a visiting place of a terminal and a data gateway is determined; the data gateway corresponding to the external data network accessed into the terminal is taken as an LBO data gateway; and whether the terminal has an address allocated by the LBO data gateway is judged, and no address is allocated to the terminal when the terminal has the address allocated by the LBO data gateway. The embodiment of the invention also discloses a mobility performance management entity for preprocessing the allocated address, the mobility performance management entity comprises a corresponding relation determination module, an LBO data gateway determination module and a judgment module, and the application of the method can avoid the repeated allocation of new addresses to the terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for address preprocessing and a mobility management entity. Background technique [0002] A mobile communication network is usually divided into two parts: an access network and a core network, where the access network is responsible for the establishment of wireless resources for terminals (UE, User Equipment) and the core network, and the core network usually includes mobile performance management nodes, data gateways, Logical nodes such as terminal subscription data server, such as figure 1 shown. figure 1 It is a schematic diagram of a mobile communication network in the prior art. [0003] Among them, the mobility management node is mainly responsible for the mobility management of the control plane, including the management of terminal context and mobility status, and the allocation of terminal temporary identities. In the MobileTelecommunication System), the...

Problems solved by technology

[0009] In the application scenarios of Intra-PLMN LBO and Inter-PLMN LBO, when the terminal arrives at the current visited location, the IP address of the visited location will be allocated, and at the same time, the IP address of the previous visited location needs to be reserved due to the requirement of business continuity. , so there will be a scenario where the UE has multiple IP addresses for the same PDN at the same time, and if the location of the UE returns to the previous visited place at this time, a new IP address will be assigned, so it will be repeated for the same PDN and the same region Allocate new IP addresses, resulting in waste of resources
