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

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

Error information is sent from a terminal adaptor that accesses a wireless network to terminal equipment coupled to access the wireless network through the terminal adaptor. The error information is sent in response to existence of any one of a plurality of errors conditions with respect to access to the wireless network. The error information includes an error type identifying a domain associated with a source of the error condition being reported and an error code providing a reject error cause for the error condition. One of the error conditions may include an unsolicited error received by the terminal adaptor from the wireless network or when a request by the TA is ignored by the wireless network.

Sending network reject/error codes from a terminal adaptor to terminal equipment through an AT command interface

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.
