Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The core idea of ​​the present invention is: configure a broadband SIM card and a narrowband SIM card with the same user number in the dual-mode single-standby terminal of the broadband-narrowband converged trunking communication system, and when the core network processes the service request of the dual-mode single-standby terminal , it is not necessary to distinguish whether the relevant user number is a broadband SIM card or a narrowband SIM card, but to determine whether to select a broadband or narrowband related processing process according to the registration status of the called number on the network side. In this way, on the one hand, when a user uses a dual-mode single-standby terminal for communication, he does not need t...

Abstract

The invention discloses a communication method and system of a dual-mode single-standby terminal. The method comprises the following steps: configuring a broadband SIM card and a narrowband SIM card with the same user number in the dual-mode single-standby terminal of a broadband and narrowband converged trunking communication system in advance; when the first core network receives a call requestof the dual-mode single-standby terminal, judging whether a corresponding called number is registered on a network side with the same bandwidth type as the first core network or not, and if so, executing a corresponding single call establishment process according to a network standard with the same bandwidth type as the first core network; otherwise, the first core network sends the call request message to a second core network, the second core network is triggered to execute a broadband and narrowband single call establishment process, and when the first core network is a broadband core network, the second core network is a narrowband core network; and when the first core network is the narrowband core network, the second core network is the broadband core network. By adopting the methodand the system, the communication complexity of the dual-mode single-standby terminal can be effectively reduced, and the method and the system are easy to implement.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a communication method and system for a dual-mode single-standby terminal in a broadband and narrowband fusion cluster communication system. Background technique [0002] Broadband and narrowband integrated trunking communication system is a hot topic in the domestic communication industry and its application field recently. The system integrates the narrowband trunking communication system represented by TeTRA and PDT and the B-TrunC broadband trunking communication system, supports unified signing, unified scheduling, and unified application. Relying on the interworking gateway, the service integration capability is improved and the call service delay is reduced. [0003] The dual-mode single-standby terminal means that the terminal can insert a broadband SIM card and a narrowband SIM card at the same time, and decide which SIM card to use for attachment and standby according...
