Relationship Between LTE and eLTE

1）         The differences are as follows:

LTE is short for Long Term Evolution. It is the fourth generation of global mobile communication technology defined by 3GPP. eLTE is a brand name of Huawei. It represents the wireless private network solution based on LTE technologies, including broadband multimedia trunking and broadband access solutions. In addition to the basic enterprise (enterprise market), "e" also includes the following two layers:

A.        Enhanced: Based on the existing LTE commercial network technologies, the system architecture, product form, and industry features are enhanced based on the current LTE commercial network technologies.

B.        Embedded: The platform is open and the LTE modular integration enables all industry partners to participate in the joint innovation of eLTE terminals and applications to build a healthy ecological chain for the dedicated network industry.

2）         The differences between the object and market are as follows:

In the early stage of broadband development of key communications, LTE is applied to the industry and requires industry-oriented adaptation. Huawei proposes the eLTE solution. Traditional mobile operators build LTE networks to provide daily voice and data services for more common users from the perspective of coverage and capacity. eLTE is oriented to public security (p*** and interior departments), military, ports, airports, subways, electric power, energy, and mines, and provides trunking dispatch by constructing eLTE networks and matching industry terminals, services with industry attributes, such as video surveillance, can improve the national informatization level, people's livelihood index, and productivity.

The eLTE solution is enhanced in the following aspects:

A.        The E2E industry solution adaptation mainly reflects the professional multimedia dispatching trunking function, industry terminal adaptation and management, unified product capability exposure platform (eSDK), protection level (IP67), and high network flexibility (fault weakening), high reliability (anti-shockproof) and high security (end-to-end encryption)

B.        The E2E industry chain adaptation is mainly reflected in the coordinated frequency application strategy of the private network and the early chip support of the industry chain.

C.        Miniaturization and mobility are mainly reflected in product equipment forms and integration, such as eLTE Rapid system and compact core network.

3） How does eLTE comply with LTE internationalization standards?

A.     eLTE is a solution that complies with the B-TrunC standard in China.

As a member of the B-TrunC Industry Alliance led by the China Communications Standards Association (CCSA) and the Ministry of Industry and Information Technology, Huawei has participated in and contributed a lot of key technologies to B-TrunC. In 2013, B-TrunC released the broadband trunking standard. Currently, eLTE has completed B-TrunC certification.

B.     eLTE is a solution that complies with the PPDR (public safety and disaster relief) standards recommended by the ITU.

As a core member of the international PPDR organization, Huawei is a key member of the PPDR and ETSI TC-RT organizations under the ITU-R. In 2014, the International Telecommunication Union (ITU) ITU-R agreed that B-TrunC (broadband trunking communications) technology standards are one of the PPDR technical standards recommended by ITU-R.

C.     eLTE will comply with 3GPP standards in the future.

eLTE follows the 3GPP key communication standardization process and actively assists TCCA in promoting the standardization of next-generation key communications. TCCA is a key communication user requirement of 3GPP. As an important member of TCCA, Huawei uses its technical advantages in 3GPP and actively promotes the implementation of requirements as technical standards. Currently, eLTE has verified the major technical issues in the 3GPP standardization process of broadband key communications, such as: 1) The voice scheduling is relatively mature, but the multimedia scheduling technology still needs to be defined. 2) Networking mode of interworking and coexistence with existing narrowband networks 3) Network reliability and flexibility

Note: The above focuses on eLTE broadband trunking. Huawei eLTE broadband network access technology is the same as the LTE broadband network access technology of carriers, meeting 3GPP standards.

In summary, a table is used to describe the differences between LTE and eLTE, as shown in the following figure.

The differences include high reliability, low delay, end-to-end encryption, emergency call, harsh environment adaptability, and industry terminal customization.
