Abstract: An electronic wireless communication device, comprising a memory region, storing a priority ordering of network identifiers, comprising at least a first wireless network identifier and a second wireless network identifier; and a network status indicator, having at least a first value and a second value. The electronic wireless communication device is arranged to carry out a network searching process, in which the electronic wireless communication device searches for available networks in an order defined by the priority ordering of network identifiers until an available network is identified and the electronic wireless communication device successfully connects to the available network. The electronic wireless communication device is arranged to omit at least the first network identifier from the priority ordering of network identifiers used during the network searching process whenever the network status indicator has the first value.

Abstract: A radio device communicates with a 4G or 5G cellular network that comprises one or more cells and supports a 4G LTM PSM or 5G MICO power saving mode for devices registered to the cellular network. When the radio device is registered to the cellular network and has the power saving mode activated, in response to determining that the radio device has data to send to the cellular network, the radio device deactivates the power saving mode and searches for a suitable cell of the cellular network for sending the data. If the radio device is unable to find to any suitable cell of the cellular network for sending the data to the cellular network, it reactivates the power saving mode.

Abstract: The embodiments of the present disclosure provide a method for searching a mobile network, where the method may include: an apparatus, obtaining a set of geographic information indicating a location of the apparatus; obtaining a set of system information corresponding to the set of geographic information, wherein the set of system information comprises at least one system; obtaining at least one band for the at least one system; and searching the at least one band for the at least one system. Besides, the embodiments of the present disclosure further provide an apparatus for searching a mobile network. Accordingly, a scope of a mobile network search may be narrowed, thus searching all systems and all bands may be avoided.

Abstract: The embodiments of the present disclosure provide a method for forming a bank of information, where the method includes: obtaining a set of information; and forming a bank of information based on the set of information, wherein the bank of information at least comprises a first set of geographic information. Furthermore, the embodiments of the present disclosure further provide an apparatus for forming a bank of information. By using the bank of information, a scope of a mobile network search is narrowed because only a part of bands or a part of systems may be searched. Accordingly, forming the bank of information contributes to avoiding searching all systems and all bands so as to save time for the mobile network search.

Abstract: Apparatus, methods, and computer programs are disclosed that include sending an update message to a core network by a voice centric user equipment coupled to a legacy access network supporting circuit switched voice service, receiving an updating accept message containing a status report of possible enhanced network capabilities of a non-legacy access network, and, in response to receiving the status report of possible enhanced network capabilities, determining whether to enable the non-legacy access network.

Abstract: A method including detecting a preference of a user terminal for a predetermined service, detecting that the current RAT does not provide the predetermined service; monitoring whether another PLMN or RAT of the first PLMN is available; upon detecting that no other PLMN or RAT of the first PLMN is available, maintaining connection to the first RAT of the first PLMN until another PLMN or RAT in the first PLMN becomes available; upon detecting that another PLMN or RAT is available, considering the first RAT of the first PLMN as disabled, and generating an information element to a memory according to which the first RAT of the first PLMN has been marked as disabled, wherein the information element is valid until a predetermined criterion is met and at least beyond a point of time when the user terminal switches to another PLMN and/or to another RAT.
