[0019] Due to the problem of PDT / LTE air interface resources, the group can only be established under the LTE network, so that the terminal currently on the PDT network cannot monitor the group that needs to be monitored, or it can only be established under the PDT network. Terminals on the LTE network cannot monitor groups that need to be monitored

Embodiment 1
[0087] Embodiment 1: PDT side process description
[0088] Figure 4 In the first embodiment of the present application, a schematic flow diagram of a group can only be established on a PDT network, and the flow includes the following steps:
[0089] Step 1: When the dual-mode single-standby terminal in the PDT network is powered on or network switched, it initiates registration with the PDT base station through C_RAND, carrying the capability indication, as shown in Table 1, where the gray part is the addition of the PDT standard.

[0091]
[0092] Step 2: The LTE single-mode terminal initiates joint group establishment to the PDT / LTE converged core network.
[0093] Step 3: Since there are LTE single-mode terminals in the group, the PDT / LTE converged core network determines that the group can only be established on the LTE network.
[0094] Step 4: The PDT / LTE converged core network notifies the PDT base station, and paging on the PDT air interface ind...

[0107] Embodiment 2: LTE side process description
[0108] Figure 5 In the second embodiment of the present application, a schematic flowchart of a group that can only be established on a PDT network includes the following steps:
[0109] Step 1: When the dual-mode single-standby terminal on the LTE network is powered on or the network is switched and registered, the PDT / LTE capability indication is carried through MS Radio Accesscapability: PDT / LTE dual-mode single-standby, PDT / LTE dual-mode dual-standby single-pass or PDT / LTE LTE dual-mode dual-standby dual-pass.
[0110] Step 2: The PDT single-mode terminal initiates joint group establishment to the PDT / LTE converged core network.
[0111] Step 3: Since there are PDT single-mode terminals in the group, the PDT / LTE converged core network determines that the group can only be established on the PDT network.
[0112] Step 4: The PDT / LTE converged core network notifies the LTE base station, and paging on the LTE air interfa...

Abstract
The present application discloses a PDT and LTE cluster paging mutual assistance method in a broadband-narrow integration system, including: a core network receiving a terminal capability report; The ability and status of the corresponding group establishment process. The present application also provides a core network device. By applying the technical solutions disclosed in the present application, no matter which network the dual-mode single-standby terminal currently resides on, the group can be monitored.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and device for paging mutual assistance in a PDT and LTE cluster under a broadband-narrow convergence system. Background technique [0002] With the continuous development of wireless communication technology, trunking communication technology has developed from an analog system to a narrowband digital trunking system. At the same time, with the increasing demand for wireless broadband by industry users, it has developed from simple voice services to multimedia represented by LTE. Business digital trunking communication system. [0003] At present, the police use the police digital trunking system (PDT). Due to the narrow bandwidth of the PDT system, it only supports voice services, short messages, GIS information and a small amount of packet data, so it has been unable to meet the increasingly urgent broadband service requirements of the police. ...
