Embodiment Construction

[0019] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0020] figure 1 Schematic diagram of a mobile communication network acquired for SI supporting reduced signaling costs according to a novel aspect. The mobile communication network 100 includes a user equipment UE 101 , a first base station eNB 102 , a second base station eNB 103 , and a packet core network (Core Network, CN) 105 . Multiple base stations communicate with each other through the X2 interface, and eNB 102 / 103 communicate with the CN 105 through the S1 interface. UE 101 can access application server and Internet 106 via wireless link 104 with eNB 102 / 103 and CN 105 . These eNBs may be implemented as eNB 102 in a conventional manner, or as eNB 103 including multiple transmission points (Transmission Points, TRPs). The wireless link 104 may specifically be a cell, a cell portion, a TRP, a side link or a beam in a hi...

Abstract

The present application provides a method for acquiring user equipment and system information, which can reduce signaling costs. In order to reduce the cost of system information broadcasting, it is necessary to reduce the total amount of periodic system information broadcasting and the frequency of on-demand system information acquisition. To reduce the total amount of periodic system information broadcasts, on-demand system information delivery is enabled. With on-demand system information broadcasting, the signaling cost is proportional to the acquisition frequency of system information. On the network side, the base station actively provides system information delivery options and delivers system information on unicast or scheduled broadcast. On the user equipment side, the user equipment determines how to acquire the system information, ie, via listening to broadcasts or via an existing operation such as a random access operation on a random access channel to send an on-demand request.

Description

technical field [0001] Embodiments of the present invention relate to network entry in a mobile communication network, and in particular to functions for processing system and configuration information. Background technique [0002] In the 3GPP Long Term Evolution (LTE) network, the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) includes multiple base stations (BaseStations, BSs), for example, with multiple mobile stations (Mobile Stations, MSs) communicate with evolved Node-Bs (Evolved Node-Bs, eNBs), where the MS is also called User Equipment (User Equipment, UE). The serving base station can communicate with multiple UEs in the serving cell by broadcasting, for example, when the multiple UEs are in idle mode, or by dedicated unicasting Communicating with multiple UEs in a serving cell, eg, when the multiple UEs are in connected mode. In a cellular (cellular) network, each serving cell periodically broadca...
