Problems solved by technology

However, since the granularity of the current local network coverage area is not defined, it may be Cell granularity or tracking area (Tracking Area, TA) granularity, and there may also be multiple types of location types in the local network area, such as 3GPP type or Non- 3GPP type, which in turn causes the UE to understand different location granularities and types when judging the local network coverage area, which increases the complexity of UE processing
[0006] In addition, due to the rise of MEC, there will be many local networks in the future, so UE needs to save a large number of local networks and the corresponding local network coverage area information, but actually when the UE judges whether its current location is in the local network coverage area, it only needs to The local network information supported by the current location is sufficient, so UE saves a large amount of local network related information and occupies a large amount of storage resources

Embodiment 1

[0062] Such as figure 2 As shown, it is a signaling flowchart of a method for establishing a local network connection provided by this embodiment. Taking UE, base station and network equipment, such as control plane nodes as examples, the steps of this method are described, specifically, the following steps are included:

[0063] Step 201: the base station obtains a first local data network (local datanetwork, LDN) list supported by its location area, the location area is the coverage area of ​​the local network where the base station is located, and the LDN list is composed of at least one local network identifier .

[0064]The local network identifier can also be called a network identifier (data network name, DNN), which refers to a network deployed locally. In order to distinguish a normal network, it is called a local network identifier, which is similar to the access point name in 4G ( access point name, APN).

[0065] When the base station is in the coverage area of...

Embodiment 2

[0077] Such as image 3 As shown, the method provided in this embodiment includes the following steps:

[0078] Step 301 and step 302 are the same as step 201 and step 202 in the first embodiment, refer to the description of the process in the first embodiment, and will not repeat them here.

[0079] Between step 301 and step 302, step 3011 is also included: a step in which the UE registers with the network.

[0080] Specifically, it includes: the UE sends a registration request message to the control plane node on the network side, and the registration request message includes an initial registration process and a re-registration process for location update. The initial registration process is the first registration after the terminal is powered on. The re-registration process of location update refers to other registration processes except the initial registration process, such as the re-registration process including the registration timer timeout, or the UE location chang...

Abstract

The invention discloses a method for establishing local network connection, a terminal and network equipment. The method comprises the steps that the terminal obtains broadcast information sent by a base station; determining a target local network identity according to a first local data network (LDN) list if the broadcast information comprises the first LDN list, wherein the first LDN list is composed of at least one local network identity; and the terminal establishes session connection through utilization of the target local network identity. According to the method, a great deal of relatedinformation of a local network coverage area is prevented from being stored in the terminal, storage resources of the terminal side are saved, the processing complexity when the terminal judges the local network coverage area is also reduced, and the local network connection efficiency is improved.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710257325.1 and the title of the invention "a method, terminal and network equipment for establishing a local network connection" submitted to the China Patent Office on April 19, 2017, the entire content of which is passed References are incorporated in this application. technical field [0002] The present application relates to the technical field of wireless communication, and in particular to a method for establishing a local network connection, a terminal and a network device. Background technique [0003] A local network refers to a network that covers a specific local area, such as a network that covers a corporate campus, campus, airport, train station, shopping mall, or stadium. The user equipment (User Equipment, UE) accesses the local gateway through the wireless access network, thereby directly accessing the corresponding local network, avoiding the detou...
