AI Technical Summary

Problems solved by technology

Since the discovery service of the UE is still going on, the network will not be able to confirm which UEs occupy the radio resources of the discovery service after losing the UE context. For these radio resources, the network cannot determine whether they can be allocated to other UEs or other services.
It can be seen from the above that it is unreasonable to directly apply the existing 3GPP radio resource release and UE context release in the proximity service

Embodiment 1

[0096] In this embodiment, the UE requests the radio network node to release radio resources, and the radio network node is the eNB serving the UE. image 3 It is a schematic diagram of Embodiment 1 of a method for maintaining and releasing UE resources in the present invention, and the method includes the following steps:

[0097] In step 301, the ProSe service is established, and the network allocates radio resources required by the ProSe service to the UE authorized to transmit signals.

[0098] In the subsequent process, if the transmitting signal UE decides to end the proximity service or release wireless service resources, it can implement the processing of requesting network release and network release resources in three ways, namely steps 302-305, steps 306-310, and steps 311-316 ; No matter which one of the above three ways is executed, continue to execute step 317 for processing.

[0099] In step 302, the transmitting signal UE sends a ProSe radio resource release r...

Embodiment 3

[0144] In this embodiment, the UE is handed over from the source eNB to the target eNB through the X2 interface, and the target eNB triggers the source eNB to release radio resources. Figure 5 It is a schematic diagram of Embodiment 3 of a method for maintaining and releasing UE resources in the present invention. In this embodiment, radio resource release required for the proximity service of the UE that transmits a signal is implemented through the X2 interface.

[0145] When the transmitting signal UE moves to the coverage area of ​​a neighboring eNB during the use of the proximity service, resource changes can be realized in two ways, respectively triggering the handover process for the source eNB and the UE, corresponding to the processing of steps 501-507 and steps 508-513; For any of the above processes, step 514 is directly executed after the corresponding steps are executed.

[0146] Step 501 , the transmitting UE is in the RRC connection state, and the source eNB d...

Embodiment 4

[0168] Figure 6 It is a schematic diagram of Embodiment 4 of a method for maintaining and releasing UE resources in the present invention. In this embodiment, radio resource release required for the proximity service of the UE that transmits a signal is realized through the S1 interface.

[0169] When the transmitting signal UE moves to the coverage of a neighboring eNB during the use of proximity services, resource changes can be realized in three ways, namely steps 601-609, steps 610-615, and steps 616-622; no matter which way is executed, After finishing the processing of the corresponding steps, directly turn to step 623 to update the monitoring configuration.

[0170] In step 601, the transmitting UE is in the RRC connection state, and the source eNB decides to handover the transmitting UE to the target cell according to the measurement report. The source eNB sends a handover request to the MME. The wireless resource required by the proximity service of the transmitti...

Abstract

The invention provides a UE resource maintenance and release method. Signal-emitting UE requests for releasing radio resources distributed for the UE; and a wireless network node releases the radio resources distributed for the signal-emitting UE in an approach service.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and equipment for UE resource maintenance and release. Background technique [0002] Modern mobile communication tends to provide diversified services to users more and more. At present, the public safety department of the United States has adopted the LTE network as the basic communication network of its public safety communication service. Proximity service between UEs is an important part of public safety communication requirements, including proximity discovery between UEs and proximity communication between UEs. Proximity discovery between UEs is the basis of direct communication between UEs. It can sense whether there is a friend user nearby, and prompt the user to perform the next operation. In the field of public security, it is helpful for members of the public security executive department to conduct task command and cooperate with each other in a ...
