Description

A method and device for determining the capability of a mobile terminal

technical field

The invention relates to mobile communication technology, in particular to a method and device for determining the capability of a mobile terminal.

Background technique

The Long Term Evolution (LTE) system introduces key transmission technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multi-antenna Multiple-Input Multiple-Output (MIMO), which significantly improves spectrum efficiency and data transmission rate (the peak rate can reach up to 50Mbit/s , downlink 100Mbit/s); and support 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz and other bandwidth allocation. While spectrum allocation is more flexible, system capacity and coverage have also been significantly improved. The LTE wireless network architecture is flatter, which reduces system delay, network construction costs and maintenance costs; moreover, the LTE system supports interoperability with other 3GPP systems. Frequency Division Duplex (FDD)-LTE has become a 4G standard that is widely used in countries and regions in the world and has the most abundant types of terminals. At present, 2G and 3G networks have achieved coverage in most communication areas; if LTE network construction is carried out, 2G, 3G and 4G networks will face long-term coexistence.

Figure 1 is a schematic diagram of the network structure of the existing 2G/3G packet domain, as shown in Figure 1, including: Short Message Service-Mobile Switching Center Gateway (SMS-GMSC), Mobile Switching Center/Visitor Location Register (MSC/VLR), Home Location Register (HLR), Base Station Subsystem (BSS), GPRS Service Support Node (SGSN), GPRS Gateway Support Node (GGSN), Radio Network Controller (RNC), Public Data Network (PDN). Among them, the interface between SGSN and BSS is Gb interface; the interface between RNC and SGSN/GGSN is IuPS interface. The Gb interface protocol is used to transmit signaling and data information, that is, the interface not only transmits signaling but also transmits Internet access data of mobile terminals.

With the continuous development of communication technology, terminals with LTE capabilities have been promoted. Due to certain limitations in time, technology and cost for large-scale network coverage, LTE networks have not achieved complete coverage. Based on network coverage issues, many LTE Terminal users can still only access 2G/3G network services. In order to provide more scientific LTE network coverage and gradually expand LTE network coverage, it is necessary to use LTE capabilities in the existing 2G/3G network environment. The terminal performs statistics, and based on the statistical data, further analyzes the activation status of the LTE service. Through service guidance and service usage analysis, mobile operators improve service content and realize LTE service promotion. To determine the application status of the LTE network and in which areas need to further strengthen the LTE coverage, it is necessary to detect the LTE capability of the mobile terminal and conduct statistical analysis on the detection results.
