Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a 5G-based Internet of things communication system, method and device.
Background
Compared with the 4G network technology, the 5G network technology has the obvious characteristic of convenience, and can provide characteristics of enhanced mobile bandwidth, ultra-reliable low-delay communication, mass machine type communication and the like. The deployment and implementation of the 5G communication network are mainly in medium-low frequency and high-frequency bands, so as to realize higher data transmission rate and allocation optimization of frequency band resources compared with the 4G network technology, wherein the medium-low frequency meets the requirements of coverage and capacity, and the high frequency band aims at supporting the requirement of capacity improvement in a hot spot area.
In 5G communication systems, a telecommunications carrier assigns each User Equipment (UE) a unique identifier, which in 4G and prior art is referred to as an International Mobile Subscriber Identity (IMSI), and in 5G communication systems is referred to as a user permanent identifier (SUPI). These permanent identifiers can be used by telecommunication operators to identify, locate and track UEs (user equipments). To avoid plaintext transmission of IMSI/SUPI, the user permanent identifier is encrypted as a hidden user identifier (SUCI) at the time of initial registration of the user equipment in the 5G communication system. In order to reduce the permanent identification of UE (user equipment) used in communication to improve security, 5G global unique temporary identification (5G-GUTI) is used in 5G communication system and is distributed by core network access mobile management function (AMF), when it receives periodic registration update request or service request message, the access mobile function sends new 5G-GUTI (5G global unique temporary identification) to UE (user equipment).
The internet of things (IoT) has gradually emerged in recent years as various applications, mainly applied to application scenarios such as smart home, smart manufacturing, and car networking, and establishes a network for exchanging and processing information of distributed entities such as objects. The implementation of IoT requires various communication technologies, such as wired/wireless communication networks, sensing technologies, security technologies, etc., based on which relevant data of various entities can be provided, and new application scenarios and values are created by collecting and analyzing the acquired data and controlling the data. Through the converged application of existing information technology and various industries, IoT can be utilized in a variety of fields such as smart home, smart manufacturing, car networking, and smart grid. Currently, with the development and progress of wireless communication technology, the growth of devices accessing to a wireless communication network is rapid, and the development of 5G network technology also enables more and more devices under smart home and smart manufacturing scenes to access to the 5G network, and the growth also brings the requirements on resources and optimization of the 5G network and user equipment.
At present, in order to ensure security, the use of a permanent identifier of a UE (user equipment) and then a 5G unique temporary identifier is reduced, and although the risk that the permanent identifier is illegally obtained and cracked is reduced to a great extent, the AMF (access mobility management function block) periodically updates the 5G-GUTI (5G global unique temporary identifier) to the device, which increases the energy consumption of the device side. Meanwhile, when only one AMF (access mobility management function) identifies the UE (user equipment), although the field length of the transmission message is reduced by using the 5G-TMSI as the unique identifier of the UE (user equipment), the temporary identifier still needs to be periodically updated to obtain the temporary identifier, which reduces the efficiency of an air interface in the process of multiple exchanges, and if the UE is located in an area with high user equipment concentration and limited capacity, the user experience is poor.

the local area ID synchronizer 2 can modify the first terminal identification in the first message into a second terminal identification to form a second message, and sends the second message to the server 3 through a 5G core network; in different time periods, the second terminal identifications are different;
the server 3 is able to receive a second message.
In this embodiment, the first terminal identifier is a terminal identifier allocated by the local ID synchronizer 2, and the first terminal identifier corresponds to the internet of things terminal 1 in a one-to-one manner within the range of the local ID synchronizer 2; the second terminal identification is a terminal identification distributed by a 5G core network; and in a set time period, the second terminal identification corresponds to the internet of things terminal 1 one to one.
Specifically, in this embodiment, the second terminal identifier is a 5G globally unique temporary identifier (5G-GUTI) used in the 5G communication system, and is allocated by the core network access mobility management function AMF, and when the AMF receives a periodic registration update request or a service request message, the access mobility function sends a new 5G-GUTI to the UE (user equipment, that is, the internet of things terminal 1).
In the solution of this embodiment, the second terminal identifier may also be 5G-TMSI allocated by the AMF under the condition that only a single AMF exists.
Before the system of this embodiment performs signal transmission, a communication path of a signal may be confirmed through a registration step, that is, the internet of things terminal 1 sends a registration message to the local ID synchronizer 2, and the local ID synchronizer 2 receives registration information of the internet of things terminal 1 and allocates a unique first terminal identifier within a range of the local ID synchronizer 2 to the internet of things terminal 1. After registration, signal communication of the registered internet of things terminal 1 is realized through the local ID synchronizer 2.
The registered internet of things terminal 1 may, if necessary, send a termination request message such that the subsequent communication session is no longer effected via the local ID synchronizer 2, but directly via the 5G core network.

The beneficial effect of this embodiment lies in:
the local area ID synchronizer 2 is used for providing a first terminal identification for the Internet of things terminal 1 for communication so as to replace a second terminal identification which is distributed by an access mobile management function (AMF) in a 5G core network and is continuously updated, so that the Internet of things terminal 1 has lower equipment energy consumption and higher air interface efficiency, and the user experience is improved.

According to any of the embodiments described above, in this embodiment:
the embodiment provides a method for optimizing UE (user equipment) identification of a fifth generation communication system and an Internet of things technology. The present embodiments may be applied to intelligent services based on 5G communication technology and IoT related technology, such as smart home, smart building, smart manufacturing. The present embodiment encompasses a method for performing UE local area identifier synchronization (LIDS) in a communication system, the method comprising: acquiring the allocated temporary identifier (5G-GUTI) from a core network Access Management Function (AMF); the temporary identifier is synchronized to a local area identifier (LID) assigned by the LIDS (local area ID synchronizer 2).
Specifically, the present embodiment aims at:
the equipment and the method mainly aim at the situation that the long-term moving range of intelligent household user equipment is small, the LIDS (local ID synchronizer 2) is deployed between a base station and the equipment without frequently updating the temporary identifier of the UE (user equipment), so that a plurality of UE (user equipment) IDs allocated by an AMF (access mobility management function block) are updated to the LIDS (local ID synchronizer 2), the IDS updates a stored ID form to be synchronized to the Local Identifier (LID) allocated by the IDS to the UE (user equipment), the 5G-GUTI (5G global unique temporary identifier) and the 5G-TMSI are not required to be directly updated to the UE (user equipment), and the energy consumption of the equipment is reduced and the air interface efficiency is improved.
More specifically, the technical solution of the present embodiment is as follows.
By adding LIDS equipment between equipment and a base station in a 5G communication system according to the method, the intelligent home user equipment can synchronize 5G-GUTI and 5G-TMSI allocated by AMF (advanced metering infrastructure) by using LUID and a core network without periodic updating, and the functions of reducing equipment energy consumption and improving air interface efficiency are realized.
The method specifically comprises the following steps:
the method comprises the steps that the intelligent home user equipment UE can send a registration request message to the LIDS, when the LIDS receives the registration request message, an LID is allocated to the UE equipment, and the ID is unique within the range of the current LIDS and is stored in the LIDS;
LIDS is a registration request message or a periodic registration update request message sent by UE to a core network, and is sent to a base station after being attached with a field of identification access management of the local IDS;
the base station may select an AMF to which the registration request message is delivered, and the base station transmits the received registration request message to the AMF;
when receiving the registration request message, the AMF allocates or reallocates a 5G-GUTI for the UE and sends the 5G-GUTI to the LIDS according to the LSID;
and the LIDS updates the received 5G-GUTI in a storage and synchronizes the mapping relation with the LIDS.
In the method, once the registration of the UE in the LIDS is successful, all message requests of the UE are sent to the base station through the LIDS;
in the method, once a plurality of UE successfully register in the LIDS, the issued messages are all subjected to ID synchronization through the LIDS and then are distributed through the LID;
in the method, when the UE does not need to perform the communication session through the LIDS any more, the LIDS and the 5G-GUTI of the UE stored in the memory are deleted by sending the termination request message and receiving the termination request message. When the UE needs to access LIDS again, the registration request message needs to be sent to IDS again
In the method, the entities of the LIDS may include a transceiver and a memory storing an ID mapping form. Further, the transceiver may include a transmitter and a receiver.
The transceiver may transmit signals to and receive signals from other network entities.
The memory may perform add, modify, and delete operations on the storage and mapping of IDs.
When the LIDS receives a registration request message of the UE, adding a group of stored data for the UE;
when the LIDS receives 5G-GUTI newly allocated by AMF for the existing UE, the change operation is carried out on the existing UE ID data;
when the LIDS receives a termination request message sent by the UE, the data of the UE is deleted.
The beneficial effect of this embodiment lies in:
the embodiment can provide the periodically updated 5G-GUTI and 5G-TMSI for the intelligent home equipment by replacing the LID, and realizes that the equipment side communicates with the LIDS by using the LID and the LIDS updates the stored global temporary identifier form to synchronize the identifier. Based on the function, the equipment can reduce the signaling messages sent and received, reduce the energy consumption of the equipment, improve the air interface efficiency and improve the user experience.
