Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 2 is a schematic flow chart of a method according to an embodiment of the present invention, and as shown in fig. 2, the group establishment method under the wideband-narrowband fusion implemented in the embodiment mainly includes:
In this step, the network support capability of the terminal and the actual overhead condition of the air interface resources of the wide and narrow band networks are considered, and the network for establishing the corresponding group resources is determined, so that the service requirement of the terminal can be ensured within the range of the terminal capability, and the appropriate network for establishing the group resources can be selected by combining the use condition of the network resources, thereby avoiding that the group service cannot be normally performed due to the absence of the air interface resources, and ensuring the overall performance of the wide and narrow band fusion system.
In practical applications, the broadband network may be an LTE network, and the narrowband network may be a PDT network, but is not limited thereto.
The group establishment request may be initiated by a terminal or a dispatcher station.
In practical application, the core network may determine the network mode support capability of the group member when the terminal performs network registration, and specifically may be implemented by the following method:
when network registration (terminal startup or network switching) is carried out, the terminal with dual-mode capability simultaneously carries dual-mode capability information to a core network. Therefore, when the core network registers the terminal, whether the terminal carries dual-mode capability information or not can be judged, if so, the terminal can be identified as a dual-mode single-standby terminal or a dual-mode dual-standby terminal according to the dual-mode capability information, otherwise, the terminal is identified as a single-mode terminal supporting the registered network.
The dual-mode capability information is capability information carried during dual-mode terminal registration, and the dual-mode capability types indicated by the dual-mode capability information include dual-mode single-standby single-pass, dual-mode dual-standby single-pass and dual-mode dual-standby double-pass.
The dual-mode single-standby single-pass mode means that the terminal in an idle state resides (registers) in only one network and uses services;
the dual-mode dual-standby single-pass means that the terminal resides (registers) in both networks and can only use services in one network at one moment;
the dual-mode dual-standby dual-call means that the terminal resides (registers) in both networks and supports concurrent service in both networks at one moment.
And if the terminal does not carry the capability in the terminal registration process, the terminal is considered to be a narrowband single-mode terminal or a broadband single-mode terminal.
Preferably, the radio resource occupation state is reported to the core network by the corresponding network according to a preset reporting period, the radio resource occupation state includes a current air interface resource occupancy rate of the network and an air interface resource occupancy rate allowed by the network, and the core network can determine whether the network has spare resources according to the two indexes.
The network configuration information of the group service priority establishment is used to indicate which network the group service is preferentially established in, and the information belongs to information that can be configured selectively, and can be specifically set by a person skilled in the art according to actual needs.
Preferably, in order to better guarantee the overall performance of the wide-narrow convergence system, the core network determines to establish a network of corresponding group resources according to a preset group establishment principle.
Specifically, the group establishment principle may include: a first principle, a second principle and a third principle. Wherein the content of the first and second substances,
the first principle is as follows: if the group has a narrow-band single-mode terminal or a wide-band single-mode terminal and the corresponding network has resources currently, establishing group resources in the corresponding network to ensure normal operation of the group service of the single-mode terminal as much as possible;
the second principle is as follows: the group resources are avoided to be established in the narrow-band network and the broadband network as much as possible, so that the overall resource overhead of the system during group establishment is reduced, and the overall performance of the system is improved.
The third principle is as follows: and preferentially establishing the group resources in the network indicated by the network configuration information preferentially established by the group service.
In order to meet the group service requirement of the terminal to the greatest extent, in the above three principles, the priority of the first principle is higher than that of the second principle, and the priority of the second principle is higher than that of the third principle.
In practical application, when a network of corresponding group resources is determined to be established in concrete time, firstly, whether each of the current broadband network and the current narrowband network has spare resources is determined according to the occupation state of the wireless resources; then, according to the specific situation of the network mode support capability of the group members, the spare resource condition of the network and the network configuration information established by the group service in priority, the network establishing the corresponding group resource is determined.
In practical application, when the broadband network is an LTE network and the narrowband network is a PDT network, the specific scenarios of the network mode support capability of the group members can be divided into four scenarios:
scenario 1): there are both broadband single mode terminals and narrow single mode terminals in the group members.
Scenario 2): there are narrowband single mode terminals and no wideband single mode terminals in the group members.
Scenario 3): the group members are provided with broadband single-mode terminals and no narrowband single-mode terminals;
scenario 4): there are neither narrowband single mode terminals nor wideband single mode terminals in the group.

Under the situation 2, namely when a narrow-band single-mode terminal exists in the group members and no wide-band single-mode terminal exists, if the current wide-band network and the narrow-band network both have spare resources, the group resources are determined to be established in the narrow-band network; if the current broadband network has spare resources and the narrowband network has no spare resources, determining to establish group resources in the broadband network; if the current broadband network has no spare resources and the narrowband network has spare resources, determining to establish group resources in the narrowband network; if the current broadband network and the current narrowband network have no vacant resources, the group is established unsuccessfully, and the method is exited;

under the situation 4, that is, when neither a narrowband single-mode terminal nor a broadband single-mode terminal exists in the group, if both a current broadband network and a current narrowband network have spare resources, determining that a group resource is established in a network indicated by network configuration information preferentially established by the group service; if the current broadband network has spare resources and the narrowband network has no spare resources, determining to establish group resources in the broadband network; if the current broadband network has no spare resources and the narrowband network has spare resources, determining to establish group resources in the narrowband network; and if the current broadband network and the current narrowband network have no vacant resources, the group is established in failure, and the method is exited.
