Problems solved by technology

However, with the continuous emergence of new services, the problem that the scheduling-based access mechanism has a long access delay and cannot be reduced will become more and more obvious.
For example, from a business point of view, a large number of cloud services will be developed in the future, and the processing delay caused by the additional processing in the cloud and the increase in data transmission delay will make users more sensitive to end-to-end delay

Embodiment Construction

[0046] As mentioned above, with the emergence of new services, users will be more sensitive to the end-to-end delay of new services. Therefore, if the access delay of the UE can be reduced, the processing delay of the equipment can be compensated to a large extent. And the data transmission delay.

[0047] In addition, from the perspective of the network topology, in order to expand the system capacity in the future, more and more small cells will be added to the original macro base station. Under this topology structure, the number of UEs under the micro base station corresponding to each small cell will be much smaller than the original macro base station. If the UE access scheme based on contention (CB) is introduced on the micro base station side, the contention conflict problem will not be too obvious and will greatly reduce the UE's access delay in many cases. However, at certain times, such as when the number of UEs in a cell is large or the total traffic volume in the ce...

Abstract

The present invention discloses a user equipment (UE) accessing method comprising: receiving access mode auxiliary information (AMAI) sent from a base station; receiving a competition-based resource informed by the base station; determining an access mode of data in a cache of the UE according to the AMAI; and if it is determined that a competition-based access mode is used, sending the data in the cache of the UE by using the competition-based resource informed by the base station. Corresponding to the aforementioned method, the present invention further discloses UE and an internal structure of the base station.

Description

Technical field [0001] This application relates to the field of mobile communication technology, and in particular to a user equipment (UE) access method, UE and base station in a cellular network. Background technique [0002] The traditional cellular network is a scheduling-based system. In a traditional cellular network, when the UE has data to send, the UE needs to send a scheduling request to the base station (eNB) first; after receiving the scheduling request, the eNB allocates uplink transmission resources for the UE and uses a dedicated control channel ( PDCCH) Notify the allocated resources of the UE. The UE can send data only after being notified of resource allocation. The foregoing interactive process of sending a scheduling request-allocating resources-notifying the result of resource allocation results in a UE access delay of at least 11 milliseconds in a scheduling-based system, and cannot be further reduced. Such a long access delay can meet the requirements of...
