Abstract

An IP address allocation method and a device are provided, so as to resolve a technical problem that an IP address conflict occurs when a control plane device and a user plane device allocate an IP address for one UE at the same time. When receiving a session establishment request message, a control plane network device may determine whether a first user plane network device is capable of allocating an IP address for a terminal device. If the first user plane network device is capable of allocating the IP address for the terminal device, the control plane network device may send an address allocation indication to the first user plane network device.

Claims8

Dependent claims

An Internet Protocol (IP) address allocation method, comprising:

receiving, by a control plane network device, a session establishment request message for establishing a session connection for a terminal device, wherein the control plane network device is a control plane network gateway device;
determining, by the control plane network device based on service information carried in the session establishment request message and based on service capability information of a first user plane network device, whether the first user plane network device is capable of allocating an IP address for the terminal device, wherein the first user plane network device is a user plane network gateway device;
and
after determining the first user plane network device is capable of allocating the IP address for the terminal device, sending, by the control plane network device, an address allocation indication to the first user plane network device.

1 more element

A control plane network device, comprising:

a receiver, configured to receive a session establishment request message for establishing a session connection for a terminal device;
and
a processor, configured to:
determine, based on service information requested by the terminal device carried in the session establishment request message and based on service capability information that a first user plane network device is able to provide, whether the first user plane network device is capable of allocating an internet protocol (IP) address for the terminal device, wherein the first user plane network device is a user plane network gateway device and the control plane network device is a control plane network gateway device;
and
after determining the first user plane network device is capable of allocating the IP address for the terminal device, send an address allocation indication to the first user plane network device.
