Description
What is a 4G Antenna Extension Cable Ipex Antenna?
The 4G Antenna Extension Cable Ipex Antenna Item CTRF-ANTENNA-FPC-7027-4338-IPEX is an Ipex antenna u, FL antenna flexible PCB antenna with cable extension mount 4G LTE antenna manufactured by C&T RF Antennas Inc.
The 4G Antenna Extension Cable Ipex Antenna Built-in Antenna comes with a 43x38mm FPCB board size, 3/5dbi gain, RG 1.13 extension cable 100mm, connector U.FL Ipex, omnidirectional vertical polarization.
When a terminal initiates an attach request or a TAU update request, it carries the ue_usage_setting parameter, indicating whether the terminal is DATA-centric or voice-centric.
What is DATA centric and what is voice-centric?
3GPP 23.221 defines it as follows
To allow for appropriate domain selection for originating voice calls, a CSFB and/or IMS/CS-voice capable UE is set to behave as “Voice-centric” or “Data-centric” in E-UTRAN:
A UE set to “Voice centric” shall always try to ensure that Voice service is possible. A CSFB and an IMS/CS-voice capable UE set to “Voice centric” is unable to obtain voice service in E-UTRAN.
(e.g. CSFB and IMS voice are not supported or the configured preferences on how to handle voice services prevent usage of any available voice services), shall disable the E-UTRAN capability, which results in re-selecting GERAN or UTRAN. The E-UTRAN capability is re-enabled by the UE under the conditions described in TS 24.301.
A voice-centric CSFB capable UE that receives “CSFB Not Preferred” or “SMS-only” indication as a result of combined EPS/IMSI attach or combined TA/LA Update procedures and is unable to obtain voice services over IMS shall disable the E-UTRAN capability, which results in re-selecting GERAN or UTRAN.
A UE set to “Data-centric” does not disable the E-UTRAN capability if voice services cannot be obtained. Upon receiving combined EPS/IMSI attach accept or combined TA/LA Update accept with “SMS-only” indication, a data-centric UE stays in the current RAT and is not allowed to use CSFB.
Upon receiving combined EPS/IMSI attach accept or combined TA/LA Update accept with “CSFB Not Preferred” indication, a data-centric UE stays in the current RAT and is allowed to use CSFB.
In other words
If the registered LTE network does not support CSFB and IMS voice services, the terminal should turn off the LTE function and reselect back to 3G/2G to ensure the use of voice services. If the LTE network supports CSFB/IMS voice services, then the terminal can remain on the LTE network.
The data-centric terminal can stay on the LTE network if it is registered to the LTE network, which neither supports CSFB nor IMS service.
The definition of 3gpp 24.008 on voice domain pre and sausage setting is as follows
9.4.1.11 Voice domain preference and UE’s usage setting
This IE shall be included:
- if the MS supports CS fallback and SMS over SGs or the MS is configured to support IMS voice or both; and
- if the MS is E-UTRAN capable.
