example 1

[0173] See Figure 5 .

[0174] 1. During the attachment process of the terminal device or the PDN connection process requested by the terminal device, the terminal device sends an attach request or a PDN connection establishment request message to the access network device (such as a base station), and the access network device sends the attach request or PDN connection establishment request message The request message is sent to the MME, and the MME can authenticate the terminal device. If the authentication passes, the MME can initiate a session establishment process to the core network device. For example, the MME can send a session establishment request message to the CGW ( Figure 5 In this process, only one arrow is used to indicate that the CGW receives the session establishment request message, and the access network equipment and MME and other equipment are not shown), and the session establishment request message can carry APN and protocol configuration items (Proto...

example 2

[0203] See Figure 6 , focusing on the situation where the DGW allocates an IP address for the terminal device, and the value of the Address AllocationPreference is IPv4 address allocation via DHCPv4.

[0204] Wherein, steps 1-5 of Example 2 may refer to Example 1, and the steps different from Example 1 are introduced below.

[0205] 6. After the default bearer is established, the DGW receives the request message ( Figure 6 The terminal equipment is also not shown, only arrows are used to illustrate the request message).

[0206] If the value of Address Allocation Preference is IPv4 address allocation viaDHCPv4, the DGW does not allocate an IP address for the terminal device temporarily, and the Sx request message sent by the DGW to the CGW carries an empty field for carrying the IP address. In this case, the terminal device needs to send a request message again to request an IP address (the request message may be, for example, a DHCP request message, or other possible requ...

Abstract

An IP address allocation method and device, used to solve the technical problem of IP address conflict caused when a control plane device and a user plane device assign an IP address to a UE at the same time; when the control plane network device receives a session establishment request message, it can determine the first Whether a user plane network device is capable of allocating an IP address for a terminal device, and if the first user plane network device is capable of allocating an IP address for a terminal device, the control plane network device may send an address allocation instruction to the first user plane network device, so that It can be clear which device is to allocate the IP address, avoiding two devices to allocate an IP address to a terminal device at the same time, thereby avoiding the situation of IP address conflict.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an IP address allocation method and equipment. Background technique [0002] In the prior art, when the user equipment (User Equipment, UE) is in the process of attaching to the network or in the process of establishing a packet data network (Packet Data Network, PDN) connection requested by the UE, the network device establishes a default bearer for the UE, and this At the same time, the network device will allocate a corresponding Internet Protocol (Internet Protocol, IP) address to the UE. Currently, generally speaking, a packet data network gateway (PDN GateWay, P-GW) allocates an IP address for the UE. [0003] With the evolution of the network architecture to the 4.5th generation mobile communication system (4.5G) / 5th generation mobile communication system (5G), the separation of the control plane and the user plane of network functions is the main tre...
