Problems solved by technology
However, when the base station broadcasts service data, the terminal access to the broadcast occurs randomly. After the terminal accesses the broadcast, it receives the service data broadcast by the base station after the access broadcast time. Accessing the broadcast, but accessing the broadcast after the start of the broadcast, will miss the service data broadcast by the base station during the period from the start of the broadcast to the moment of its own access to the broadcast. Therefore, when the base station broadcasts service data, the terminal will not Degraded experience for users who access the broadcast in a timely manner

Embodiment Construction
[0027] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0028] The term "and / or" in this article is only an association relationship to describe the associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, it can mean that A exists alone, A and B exist at the same time, and A and B exist independently B these three cases.
[0029] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different processes for the same object, rather than to describe a specific sequence of objects.
[0030] In addition, the terms "including" and "having" mentioned in the description of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is n...

Embodiments of the present application provide a service data transmission method and device, which relate to the communication field. The method includes the following steps: receiving a service request sent by a terminal, the service request carrying an identifier of target service data; determining a target broadcast data stream that currently has target service data; sending the target broadcast data stream after the current moment to the terminal; The base station sends a request for assistance in transmission, and the request for assistance in transmission is used to instruct the micro base station to send to the terminal the target service data transmitted from the start time of the transmission of the target broadcast data stream to the current moment in the target broadcast data stream. The method can transmit the service data broadcast by the macro base station within a period of time from the beginning of accessing the broadcasting to the terminals that do not access the broadcasting in time. Therefore, no matter when the terminal accesses the broadcast, it can completely receive service data and improve user experience.
Description
technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a method and device for transmitting service data. Background technique [0002] With the rapid development of the mobile Internet scale, more and more users watch high-definition video, online video-on-demand and other types of services through terminals (mobile phones, tablet computers, etc.) and mobile networks, which makes the network's demand for carrying capacity more and more . On the other hand, in some typical scenarios, there is a requirement that a large number of terminals request the same service at the same time. In the existing mobile communication network, when multiple terminal devices request the same service data successively, the base station equipment needs to allocate independent transmission resources for each terminal device, and send service data to each terminal device separately, that is, unicast way, resulting in a large amo...
