US 2020/0029375 A1 · SESSION CONNECTION ESTABLISHMENT METHOD AND CONTROL PLANE NETWORK ELEMENT

Abstract

Embodiments of the application disclose a session connection establishment method and a control plane network element, to select a proper user plane network element from a plurality of distributed user plane network elements for a terminal device that requests a service. In one embodiment, the control plane network element may determine a first user plane network element set from a plurality of distributed user plane network elements based on a service, to select, from the first user plane network element set, a first target user plane network element that supports the service, and establish a session connection of a terminal device. According to the embodiment, a proper user plane network element can be selected from a plurality of distributed user plane network elements for a terminal device that requests a service, thereby improving working efficiency when the control plane network element establishes a session connection of the terminal device.

Dependent claims

A session connection establishment method that is applied to a mobile communications network that comprises a core network, the method comprising the operations of:

determining, by a control plane network element in the core network, a first user plane network element set from a plurality of preset user plane network element sets of the core network of the communications network based on a service requested by a terminal device, wherein the first user plane network element set comprises a plurality of first user plane network elements;
selecting, by the control plane network element from the first user plane network element set, a first target user plane network element that supports the service;
and
establishing, by the control plane network, a session connection of the terminal device based on the first target user plane network element.

1 more element

A control plane network element, comprising:

at least one processor;
and
a computer readable medium in communication with the at least one processor, the computer readable medium storing computer readable instructions stored thereon that, when executed by the at least one processor, cause the control plane network element to:
determine a first user plane network element set from a plurality of preset user plane network element sets in the core network based on a service requested by a terminal device, wherein the first user plane network element set comprises a plurality of first user plane network elements;
select, from the first user plane network element set, a first target user plane network element that supports the service;
and
establish a session connection of the terminal device based on the first target user plane network element;
wherein the control plane network element is applied to a mobile communications network, and is located in a core network comprised in the mobile communications network.

5 more elements

A session connection establishment system, comprising:

a control plane network element in a core network;
and
a first target user plane network element;
wherein the control plane network element is configured to:
determine a first user plane network element set from a plurality of preset user plane network element sets in the core network based on a service requested by a terminal device, wherein the first user plane network element set comprises a plurality of first user plane network elements;
select, from the first user plane network element set, a first target user plane network element that supports the service;
and
establish the session connection of the terminal device based on the first target user plane network element.
