AI Technical Summary

Benefits of technology

The technology described in this patented method helps reduce mobile device's power consumption while reducing its battery life time during different states like FACH (Forward Access Channel) or IDLE mode. This results in better performance at both high-speed moving objects such as cars on streets with many people waiting).

Problems solved by technology

This patented technical problem addressed in the patents relates to improving mobile device's ability to switch connections during Long Term Evolved ("LTE") or New Carrier Type Wireless access," particularly with regards to reducing power consumption caused by unnecessary signaling exchange processes at both ends of the call set up period.

Embodiment 1

[0077] see figure 1 As shown, this embodiment provides a method for controlling cross-system handover of a UE in an enhanced CELL_FACH state, including:

[0078] The network sends interRAT measurement-related parameters to the UE, and the interRAT measurement-related parameters may include parameters such as measurement report trigger criteria and measurement quantities. For example, the network may configure interRAT measurement-related parameters for the UE through a SystemInformation message or an RRC dedicated signaling message (such as Measurement Control).

[0079] According to the received interRAT measurement-related parameters, the UE performs interRAT measurement. When the interRAT measurement report trigger criterion is met, the UE sends an uplink radio resource control message to the network, for example, a cell update Cell Update message, which contains interRAT measurement information, etc. . For example, as shown in Table 1, the interRAT measurement information m

Embodiment 2

[0086] see figure 2 As shown, this embodiment provides a method for controlling cross-system handover of a UE in an enhanced CELL_FACH state, including:

[0087] The network sends the interRAT measurement-related parameters to the UE, and the measurement-related parameters may include parameters such as measurement report trigger criteria and measurement quantities. For example, the network may configure interRAT measurement-related parameters for the UE through a System Information message or an RRC dedicated signaling message (such as Measurement Control).

[0088] According to the received interRAT measurement-related parameters, the UE performs interRAT measurement. When the interRAT measurement report trigger criterion is met, the UE sends an uplink radio resource control message to the network, for example, a Measurement Report message, which contains interRAT measurement information, etc. .

[0089] After receiving the Measurement Report message, the network determines

Embodiment 3

[0092] see image 3 As shown, this embodiment provides a method for controlling cross-system handover of a UE in an enhanced CELL_FACH state, including:

[0093] The network sends interRAT measurement related parameters and traffic measurement related parameters to the UE. The interRAT measurement-related parameters may include parameters such as a measurement report trigger criterion and a measurement amount, and the traffic measurement-related parameters may include an uplink traffic trigger threshold. For example, the network can configure interRAT measurement related parameters for the UE through SystemInformation or RRC dedicated signaling messages (such as Measurement Control); the network can also configure traffic measurement related parameters for the UE through System Information or RRC dedicated signaling messages; the network can also The parameters related to the interRAT measurement and the parameters related to the traffic measurement can be sent to the UE at the

Abstract

The invention discloses a switching control method and a system for a user device, which comprises directly switching the user device under a CELL_FACH state to a RRC_CONNECTED state in LTE, or at first immigrating the user device under the CELL_FACH state to a CELL_DCH state, and then switching the user device from the CELL_DCH state to the RRC_CONNECTED state in the LTE, thus effectively reducing data loss.
