- the above information can be obtained from the system message or from the MeasConfig cell in the RRC Reconfiguration (RRCConnectionReconfiguration) message.
- the valid time of the variable VarMeasConfigForFR can be set.
- the valid time of the variable VarMeasConfigForFR can be set to 8 hours. If the UE does not return to the LTE system within 8 hours, the UE will clear this variable. If the UE returns to the LTE system within 8 hours, the UE will update this variable according to the system message.
- the RRCConnectionRelease message may also carry a list of frequency points, indicating that those frequency points need to be measured in the target system. The UE will update the variable V ar M eaS C 0n figF 0 rFR in conjunction with the frequency information obtained from the system message or from the RRCConnectionReconfiguration message.
- FIG. 11 is a flowchart of a UE handover from an LTE system to a GSM system according to an embodiment of the present invention, where the process describes that the UE performs reselection from the LTE cell to the GSM.
- the signaling flow chart of the autonomous measurement as shown in FIG.
- Step S1102 The UE first camps on the LTE network, and the UE receives the system message from the cell, and obtains the system of the UE in the cell. Internal co-frequency, inter-frequency neighbor information. The UE saves this information in the variable VarMeasConfigForFR.
- Step S1104 The UE initiates an RRC establishment process in the camped cell to establish an RRC connection.
- Step S1106 The LTE system sends a MobilityFromEUTRACommand message to the UE to switch the UE to the GSM system due to a voice call or the like. At the same time, the message also carries a FastRetumlndication indication, indicating that the UE needs to perform the frequency of the LTE system in the GSM system.
- Step S1108 The UE performs voice service after moving to the GSM network, and according to the variable
- VarMeasConfigForFR Information such as LTE frequency points stored in VarMeasConfigForFR is measured. After the UE completes the call in the GSM network, the service is released, and after entering the idle state. Cell reselection is performed using the measurement result of the LTE network, and is reselected back to the LTE system.
- the MobilityFromEUTRACommand message can also carry a list of frequency points, indicating which frequency points need to be measured in the target system. The UE will update the variable VarMeasConfigForFR in conjunction with the frequency information obtained from the system message or from the RRCConnectionReconfiguration message.
- the network side may also carry information such as Q-RxLevMin, threshX-High threshX-Low CellReselectionPriority corresponding to the frequency point.
- the MobilityFromEUTRACommand message may also carry the valid time of the variable VarMeasConfigForFR, and the effective time may be expressed as the number of times the UE changes in the GSM system. For example, it is stipulated that the VarMeasConfigForFR is valid for the time change of the cell in the GSM system 8 times, and the Bay U UE will clear this variable after 8 cell changes in GSM.
- Embodiment 3 (the UE quickly reselects from the LTE system to the GSM system): The flowchart of the embodiment is similar to that shown in FIG. 10, and the following is described in the following: 1. The UE first resides in the LTE network, and the UE The system receives the system message, and obtains the intra-frequency and inter-frequency neighbor information of the UE in the cell.
- the system message also carries a FastRetumlndication indication, which indicates that the UE needs to measure the frequency and/or the cell of the LTE system according to the LTE frequency point and/or the cell information broadcasted in the system message in the GSM system.
- the UE saves the frequency and/or cell information of these LTE systems in the variable VarMeasConfigForFR.
- the priority of the LTE frequency point is higher than the GSM frequency point priority.
- the FastRetumlndication may be instructed by the system to indicate whether the UE needs to measure the LTE system in different systems such as GSM ⁇ UMTS ⁇ CDMA.
- the UE initiates an RRC establishment procedure in the camped cell to establish an RRC connection.
- the LTE system sends a MobilityFromEUTRACommand message to the UE to switch the UE to the GSM system due to a voice call or the like.
- the UE performs voice service after moving to the GSM network, and performs measurement according to information such as the LTE frequency point saved in the variable VarMeasConfigForFR. After the UE completes the call in the GSM network, the service is released, and after entering the idle state. Cell reselection is performed using the measurement result of the LTE network, and is reselected back to the LTE system.
- the system message and the MobilityFromEUTRACommand message may also carry a list of frequency points, indicating that those frequency points need to be measured in the target system.
- the UE will combine from system messages or from The frequency information obtained in the RRCConnectionReconfiguration message is used to update the variable VarMeasConfigForFR. If a certain frequency point has not appeared before in the system message or RRCConnectionReconfiguration, the network side may also carry information such as Q-RxLevMin, threshX-High threshX-Low CellReselectionPriority corresponding to the frequency point. Among them, system messages or MobilityFromEUTRACommand messages can also carry variables
- the effective time of VarMeasConfigForFR can be expressed as the number of times the UE changes the cell in the GSM system. For example, if VarMeasConfigForFR is specified to be a time change of 8 times in the GSM system, the UE will clear this variable after 8 cell changes in GSM. If the UE returns to the LTE system before completing the cell update in the GSM system, the UE will update the variable VarMeasConfigForFR ⁇ according to the system message or the RRCConnectionReconfiguration.
- modules or steps of the present invention can be Implemented by a general-purpose computing device, which may be centralized on a single computing device or distributed over a network of computing devices, optionally, they may be implemented by program code executable by the computing device, such that They may be stored in a storage device by a computing device, and in some cases, the steps shown or described may be performed in an order different than that herein, or they may be separately fabricated into individual integrated circuit modules, or Implementing multiple modules or steps in them as a single integrated circuit module.
