Problems solved by technology

[0003] However, LTE does not support circuit domain (Circuit Switch, referred to as CS for short) services, therefore, the terminal cannot directly establish a CS call in the LTE cell
If a terminal resides in an LTE cell and the terminal is called by a CS domain service, the LTE system cannot handle the CS domain service call, resulting in call failure

Embodiment 1

[0023] figure 1 It is a flow chart of a terminal called processing method according to Embodiment 1 of the present invention, and the process includes the following steps:

[0024] Step S102, the terminal residing in the LTE cell is called by the circuit domain service;

[0025] Step S104, the network side establishes a radio resource control (Radio Resource Control, RRC for short) connection with the terminal;

[0026] Step S106, the terminal sends a message for requesting establishment of a circuit domain service to the network side;

[0027] Step S108, the network side sends to the terminal the carrier frequency information of the Global system for Mobile Communication (GSM for short) network cell to which the terminal needs to be redirected;

[0028] Step S110, the terminal establishes a CS domain service in the GSM cell, wherein the terminal establishes the CS domain service in the GSM cell, including the following steps: the terminal sends a radio resource control conn...

Embodiment 2

[0047] In this embodiment, a test scheme for the scheme provided in Embodiment 1 is provided. It should be noted that any message involved in Implementation 1 can be detected to detect whether the message is sent and / or received Success, and feedback the detection result. The test method provided in this embodiment detects relatively important messages, so that the normal operation of the network can be guaranteed with the least test procedures. The test method provided in this embodiment can be applied to an actual network, and at the same time, can also be applied to a simulated system. When applied to a simulated system, the terminal is connected to the system simulator through a GSM or LTE wireless interface; the system simulator Simulate LTE cells and GSM cells, and verify terminal capabilities based on received terminal messages.

Abstract

A terminal called processing method, terminal called test method and Long Term Evolution (LTE) system are provided. The terminal called processing method includes the following steps: a network side of the LTE system sends a paging message to the terminal which is called by a circuit switch service and resident in the LTE cell (S102); the terminal establishes a radio resource control (RRC) link with the network side (S104); the terminal sends the network side the message for requesting to establish the circuit switch service (S106); the network side sends the terminal the carrier frequency information of the Global System for Mobile Communication (GSM) cell where the terminal needs to be redirected (S108); the terminal sends a RRC connection request message to the GSM cell; the GSM cell establishes a call bearer with the terminal; and the terminal establishes the circuit switch service in the GSM cell (S110). By applying the invention, when called by the circuit switch service, the terminal resident in the LTE cell can fallback to the corresponding network cell to establish the circuit switch service.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a terminal call processing and testing method and a long-term evolution system (Long Time Evolution, referred to as LTE). Background technique [0002] As a research project of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short), the LTE has formed a complete wireless communication standard and is gradually being promoted around the world. [0003] However, LTE does not support a circuit domain (Circuit Switch, CS for short) service, therefore, a terminal cannot directly establish a CS call in an LTE cell. If a terminal resides in an LTE cell and the terminal is called by a CS domain service, the LTE system cannot handle the CS domain service call, resulting in call failure. Contents of the invention [0004] The main purpose of the present invention is to provide a terminal called processing solution to at least solve the above pr...
