Aspects of the subject disclosure may include, for example, embodiments that include accessing a group of user controlled mobile equipment access point names in response to the device detecting a user controlled mobile equipment access point name elementary file (EF_UMEAPN) stored in a memory of a universal integrated circuit card (UICC). An operator stores access point name information and the access point name information comprises the EF_UMEAPN. Further embodiments include configuring the device according to the group of user controlled mobile equipment access point names. Other embodiments are disclosed.

Systems, devices and methods for managing access point name information by operators and users on the SIM

The described technology is generally directed towards transferring coverage enhancement information from a terminal adapter to a terminal equipment. In one aspect, a terminal equipment can send a communication command to a terminal adapter requesting return of coverage enhancement information, and receive the coverage enhancement information from the terminal adapter. The terminal equipment provides access to the coverage enhancement information to a program running on the terminal equipment. In another aspect, a terminal adapter activates coverage enhancement information reporting, and sends coverage enhancement information to a terminal equipment. The terminal adapter monitors for a coverage enhancement state change.

Transferring coverage enhancement information from terminal adapter to terminal equipment

Communication systems can enhance customer experience by quickly and efficiently associating and disassociating radio access technologies (RATs) from available networks in a deployment. In one aspect, a user equipment (UE) can optimize usage of a PLMN selector file (e.g., HPLMNwACT) stored within the subscriber identity module (SIM) that comprises a combination of mobile country code/mobile network code (MCC/MNC) data and RAT data (e.g., customized based on mobile network operator (MNO) requirements and/or deployments). Moreover, during PLMN selection, the UE can only search for a RAT that is associated with a MCC/MNC combination, resulting in faster PLMN selection and reduced UE resource consumption. Further, the PLMN selector file can be modified based on MNO preferences via an over-the-air update.

Optimization of access technology search in multiple equivalent home public land mobile network (EHPLMN) deployments

A system that incorporates the subject disclosure may include, for example, responsive to a determination that a number of failed service requests directed to a first access technology exceeds a threshold for a maximum number of failed service requests, performing cell selection associated with a second radio access technology during an overload mitigation time duration; and responsive to a determination of an expiration of the overload mitigation time duration, transmitting additional service requests associated with the first radio access technology. Other embodiments are disclosed.

Apparatus and method for management of service requests in an overload environment

A system for efficiently transmitting requests for data access from a wireless communications device to a radio access network. Requests for data access may be aggregated to more efficiently use radio resources. Aggregated requests may not be transmitted until a total number of requests or size of aggregated requests exceeds a threshold. Regardless of aggregation, requests may be stored until a timer expires, and then transmitted to the radio access network. Request priority, environmental data, and device data may be taken into account in determining when to transmit requests for data access.

Efficient processing of radio resource requests

A system that incorporates the subject disclosure may include, for example, responsive to a determination that a first communication session is in a first state and a first sub-state, monitoring for an active timer associated with the first sub-state, where the first state and the first sub-state are defined by a communications protocol. The system can, responsive to a detection of the active timer, monitor for a packet switching service initiation request generated by the applications processor. The system can, responsive to detecting the packet switching service initiation request, temporarily prevent the packet switching service initiation request from being transmitted by the transceiver. Other embodiments are disclosed.

Apparatus and method for managing requests for service

A system that incorporates the subject disclosure may include, for example, accessing configuration information, monitoring for radio resource control connection requests being transmitted from the wireless communication device to a first server of a first cell of a network, determining whether failed radio resource control connection requests satisfy a cell barring threshold based on the monitoring and based on the configuration information, and responsive to a determination that the cell barring threshold has been satisfied, causing the wireless communication device to perform cell selection for a second cell of the network and to perform cell barring of the first cell. Other embodiments are disclosed.
