To receive E-UTRAN pagination, UEs in idle mode for monitoring PDCCH for the channel value used to indicate the pagination RNTI: RNTI-P. The EU needs only to monitor the PDCCH channel at certain specific times (i.e. the subframes are specified for individual radio frames introduction to the framework structure of the LTE radio.). At other … Read more

The UE carried out a restriction of access check during connection establishment. This function provides a means of controlling traffic load from the EU. There are separate facilities for control of Mobile originated (MO) calls and signaling. On top of regular class, parental control, specific Access Control Services (SSAC) can be applied. SSAC facilitates separate … Read more

Closed Subscriber Group LTE supports the existence of cells which are only available for a limited set of EEC- A closed Subscriber Group (CSG). In order to prevent attempts to register on the UES CSG cells on which they do not have access to, up to the CSG supports white list, that is, a list … Read more

UE Accessibility Verification If the best cell on the LTE frequency have banned or are protected, up to exclude This cell from cell selection list. In that case may consider UE the cell on the same frequency, if banned cell indicates (by using fields ‘ intraFreqReselection ‘ in SIB1), intra-frequency selection is not allowed for … Read more

E-UTRAN configures a priority for all applicable frequencies for each RAT. In addition to the priorities of specific cells that are optionally provided by SI, E-UTRAN can assign specific EU priorities through dedicated signaling. Since frequencies are indicated in the information system, the EU is expected to take into account only the cell reselection which … Read more

Cell selection consists of the UE seeking stronger cell on all supported frequencies of each transport supported rat until it finds a suitable cell. The main requirement for cell selection is that it should not take too much time that becomes more difficult with the growing number of frequencies and rats to be searched. The … Read more

How UE select suitable cell in LTE Here write in simple words how UE select suitable cell in LTE. After the UE has selected a PLMN, is a done selecting cell – in other words, looking for an appropriate cell camp. While camping on the cell, and that is the UE acquires broadcast. Subsequently, the … Read more

Means for transmitting UE In order to avoid signaling of the radio access capability of the UE via an air interface at each transition from RRC_IDLE to RRC_CONNECTED, the core network stores AS capabilities (such as E-UTRA and the possibility GERAN), while the UE is in the RRC_IDLE / EMM-registered. After the connection S1, the … Read more

Depending on the type of measurement, the UE can measure and report any of the following: serving cell; list of cells (e.g., cells shown as part of the object of measurement); cells are found at the frequency set (ie cells are the cells that are not listed, but found UE). For some rats, the UE … Read more

The E-UTRAN can configure the UE to report measurement information to support the control of UE mobility. The following measurement configuration elements can be signaled via the RRC Connection Reconfiguration message. E-UTRAN may configure the UE to report measurement information to support the control elements mobility. Following measurement configuration message can be supplied via the … Read more
