Abstract: Disclosed is a group trigger method, apparatus, and system. In embodiments of the present invention, the group trigger system includes: an interworking function (IWF) entity, configured to send a trigger delivery request to an entity that has a trigger function; and the entity that has a trigger function, configured to, after receiving the trigger delivery request sent by the IWF entity, return a trigger delivery acknowledgement message to the IWF entity, and delivers, according to the trigger delivery request, an acquired group trigger payload to a user equipment UE. The entity that has a group trigger function delivers the group trigger payload to the UE, so as to effectively implement group trigger, avoid point-to-point trigger, and save system resources.

Abstract: Embodiments of the present application provide a coverage enhancement (CE) function implementation method and a device. The method may include obtaining, by a first radio access network node, CE authorization information of a terminal. The CE authorization information may include at least one of the following: CE indication information and an authorized CE level range. Further, the method may include determining, by the first radio access network node based on the CE authorization information, whether a CE level of the terminal meets an authorization requirement, and controlling, based on an authorization result, use of a CE function by the terminal. It can be learned that, not all terminals can use the CE function, but only an authorized terminal can use the CE function, to ensure that the terminal can use the CE function properly within an authorized range and to improve radio channel resource use efficiency.

Abstract: A data communication method, a communication system, and related devices are configured to establish a transaction identifier (TI) in a user equipment (UE). The data communication method includes the following steps. A mobility management entity (MME) receives a request message and obtains ability information of the UE. If the UE has an ability to access a Universal Terrestrial Radio Access Network/GSM/EDGE Radio Access Network (UTRAN/GERAN), the MME generates the TI. A communication system and related devices are also provided. Thus, the TI is effectively established in the UE, so as to ensure normal processing of the UE.
