Problems solved by technology

However, the communication between things is not always the way of pursuing high-speed broadband like people and people. After a large number of devices are connected to the network, only a small amount of data transmission is required or the frequency of data transmission is very low; Frequent charging can be performed during communication. Due to the particularity of the environment and the huge quantity of many devices, the power consumption required to support their communication is extremely low.
For example, a large number of water meters, fire extinguishers, sprinkler irrigation switches in 10,000 mu of fertile land, weather stations in harsh environments, etc., after they are connected to the Internet, they only need data transmission with very low frequency and very little capacity, and relying on external power supply is very time-consuming and labor-intensive. 4G and 5G cellular networks cannot meet their needs, and a network with low bandwidth, low power consumption and wide coverage is the best choice

Embodiment 1

[0039] In this embodiment, the DECOR technology is used to realize the selection of the NB-IOT user core network. In the network architecture of this embodiment, the home base station gateway acts as an interface agent between the home base station and the core network, and connects the home base station and the core network respectively.

[0040] Such as figure 1 As shown, the method for selecting the NB-IOT user core network in this embodiment includes:

[0041] Step 110, after receiving the relocation message sent by the core network device, the home base station gateway sends a core network relocation indication message to the home base station;

[0042] After a UE that supports NB-IOT accesses the core network for the first time, the core network equipment obtains the special-purpose attribute information of the UE and decides to select a core network suitable for serving NB-IOT users for the UE. In order to relocate the UE to a dedicated core network , the core network d...

example 1

[0090] In this example, the femtocell gateway acts as the interface agent between the femtocell and the core network, connecting the femtocell and the core network respectively. The network structure diagram of the femtocell is as follows Figure 5 shown.

[0091] In this example, after receiving the relocation message, the home base station gateway performs core network selection locally, and does not notify the home base station of the core network selection result. Such as Figure 6 As shown, the specific steps in this example are as follows:

[0092] Step 1: The UE type information acquired by the core network equipment is NB-IOT user, and it is decided to select a core network equipment supporting NB-IOT for the UE. The core network device sends a relocation message to the home base station gateway; the message contains one or more of the following information: the S1 interface uniquely identifies the UE's flag information, the UE's first UE initial direct transmission ...

example 2

[0099] In this example, the home base station gateway performs core network selection locally after receiving the relocation message, and notifies the home base station of the core network selection result. Such as Figure 8 As shown, the steps for this example include:

[0100] Step 1: The UE type information acquired by the core network equipment is NB-IOT user, and it is decided to select a core network equipment supporting NB-IOT for the UE. The core network device sends a relocation message to the home base station gateway, which contains one or more of the following information: the S1 interface uniquely identifies the UE's flag information, the UE's first UE initial direct transmission message, and the core network relocation information (C-SGN group flag, or designate one or more C-SGN flag information such as C-SGN ID or name), UE GUTI information;

[0101] Step 2: After the home base station gateway receives the relocation message, it implements the NNSF function l...

Abstract

The invention discloses a narrow band Internet of things user core network selection method and a communication device. After a home eNB gateway or a donor eNB receives a reroute message sent by a core network device, a core network reroute indication message is sent to a home eNB or a relay node; after the home eNB gateway or the donor eNB receives a user equipment UE initial direct transfer message sent by the home eNB or the relay node, the UE initial direct transfer message is routed to the core network device in support of an NB-IOT (Narrow Band Internet Of Things); and the core network device in support of the NB-IOT is the new core network device selected for an NB-IOT user by the home eNB gateway or the donor eNB. According to the scheme of the invention, under the home eNB gateway, an NB-IOT user core network selection function is realized; the application of the narrow band Internet of things technology to a home eNB gateway scene can be satisfied; the network efficiency is improved; and influences of a great deal of specially-purposed user equipment existing in a network on general users can be avoided.

Description

technical field [0001] The present invention relates to mobile communication, and more specifically, to a method for selecting a core network of a narrowband Internet of Things (NB-IOT: NarrowBand Internet Of Things) user and a corresponding communication device. Background technique [0002] In order to provide users with a higher service rate and reduce the cost of using high-speed services, and to make up for the lack of coverage of users' homes or offices by existing distributed cellular wireless communication systems, wireless communication network operators can use home base stations It is converted into a wireless broadband access device that is easy to carry and install, and is provided for users to place in their homes or offices. A femtocell is a small, low-power femtocell, mainly used in small-scale indoor places such as homes and offices. The femtocell is connected to the core network of the mobile operator through wired access equipment such as indoor cables, D...
