Embodiment Construction

[0046] The present invention improves the existing point-to-point call release process by improving the message processing flow of the LTE core network. After the point-to-point call is established, the calling UE conducts a point-to-point call with the called UE. When the call needs to be ended, the LTE core network is used to realize the release of the point-to-point call. The following is an introduction through the first embodiment of the present invention to the fifth embodiment of the present invention.

[0047] figure 1 It is a flowchart of a method for releasing a point-to-point call in a TD-LTE digital trunking system according to Embodiment 1 of the present invention. Such as figure 1 As shown, the method at least includes the following processes.

[0048] Step 101: The LTE core network device sends a point-to-point release message to the first UE and the second UE performing point-to-point communication, respectively.

[0049] Step 102: The LTE core network devic...

Abstract

The invention provides a point-to-point call release method and device in a time division-long term evolution (TD-LTE) digital trunked communication system. An LTE core network device respectively sends point-to-point release messages to first user equipment (UE) and second UE which carry out point-to-point communication, the LTE core network device obtains point-to-point release completion messages respectively from the first UE and the second UE, and wireless load bearing resource release is carried out on the first UE and the second UE according to the point-to-point release completion messages. Through the adoption of the point-to-point call release method and device in the TD-LTE digital trunked communication system, communication time delay and network architecture complexity can be reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for releasing a point-to-point call in a Time Division Long Term Evolution (TD-LTE) digital trunking system. Background technique [0002] At present, in the digital trunking communication system using TD-LTE technology, three schemes can be used to provide voice services when making point-to-point calls, including: Single Radio Voice Call Continuity (SRVCC for short), Circuit Switch Fallback (CircuitSwitchFallBack) , CSFB for short) and Voice over Long Term Evolution (VoLTE for short). [0003] The above three existing solutions all need the support of the Circuit Switching (Circuit Switch, CS for short) domain or the Internet Protocol Multimedia Subsystem (Internet Protocol Multimedia Subsystem, IMS for short) domain. During the point-to-point call release process, the CS domain device or the IMS domain device controls the release of resources, and the LTE...
