Embodiment 1

[0068] Figure 7 It is a schematic diagram of the APN correspondence relationship between the global resource processing unit and the PGW resource processing unit in Embodiment 1. The APN correspondence relationship is shown in the figure. APN1 and APN2 are configured in the same group, and the resource processing unit 1 obtains from the corresponding APN respectively. To the IP sub-pool, if the IP segment corresponding to APN1 is relatively small and the IP segment corresponding to APN2 is relatively large, when all the resources under APN1 are assigned to resource processing unit 1, when resource processing unit 2 requests the IP sub-pool, the global resource The processing unit searches for other APNs under the ID according to the group ID where APN1 is located, such as APN2, and allocates the IP segment under APN2 to the resource processing unit 2 carrying APN1. While solving the problem of idleness, operators need to share IP resources under different APNs, making IP allo...

Embodiment 2

[0070] Figure 8 It is a schematic diagram of the APN corresponding relationship between the global resource processing unit and the PGW resource processing unit in the second embodiment. The APN corresponding relationship is shown in the figure. APN1 and APN2 are configured in the same group ID1, and APN1 and APN3 are configured in the group ID2. Resource processing Unit 1 obtains the IP sub-pool from the corresponding APN respectively. When the resource processing unit 2 requests the IP sub-pool, the global resource processing unit allocates the IP segment under APN1 from the group ID2. Therefore, while solving the problem of APN3 resource shortage and avoiding the problem of idle IP resources under APN1, operators need to share IP resources under different APNs, so that IP allocation The way is more flexible.

[0071] Based on the same inventive concept, an IP address allocation device is also provided in the embodiment of the present invention. Since the problem-solving p...

Abstract

The invention discloses an IP address assignment method and equipment. The method comprises the steps as follows: determining IP address fields corresponding to all access point names and grouping all the access point names; after receiving an IP address assignment request message from a resource processing unit of a group data gateway, determining the access point name in the request message from the resource processing unit of the group data gateway and the group that the access point name belongs; determining IP address fields belonging to the group; and assigning the IP address fields for the resource processing unit of the group data gateway, wherein the assigned IP address fields belong to the IP address field of the group. The invention solves the problem of IP resource sharing under different access point names, provides a flexible and efficient IP assignment scheme for mobile terminals, enhances the flexibility in IP assignment of user equipment, and satisfies different requirements of different operators.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an IP address allocation method and equipment. Background technique [0002] UE (User Equipment, User Equipment) IP (Internet Protocol, Internet Protocol) address allocation methods include DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol), DIAMETER, RADIUS (Remote Authentication Dial In User Service, dial-up user remote authentication service system ; Diameter (diameter) protocol is an upgraded version of RADIUS (radius), address pool mode, etc. The allocation method of the address pool is described below. [0003] 1) The logical relationship between the global resource processing unit and the PGW (PDN Gateway, packet data gateway, PDN: PacketData Network, packet data network) resource processing unit. [0004] figure 1 It is a schematic diagram of the relationship between the global resource processing unit and the PGW resource processing unit....
