Enhanced paging for an LTE mobile satellite system (MSS-LTE) network, including determining that a user terminal (UT) is in a second state in which the UT has established a Non-Access Stratum (NAS) protocol signaling connection with the network and an active Radio Resource Control protocol (RRC) connection with the network; determining, as a result of the UT being inactive while the UT is in the second state, that the UT is in a third state in which the UT maintains the NAS connection and releases or suspends the RRC connection; receiving a request to establish a multimedia session with the UT; transmitting, in response to receiving the request and the UT being in the third state, an E-RAB SETUP REQUEST including a priority value indicating the session is suitable for a high penetration alerting procedure; receiving the E-RAB SETUP REQUEST; and in response to receiving the E-RAB SETUP REQUEST, transmitting a high penetration alert signal to the UT.

A method of operating a Long-Term Evolution (LTE) mobile satellite system (MSS-LTE) communication network, the method comprising: determining that a first user terminal (UT) is in a first state;determining, as a result of an attach procedure for the first UT to the MSS-LTE while the first UT is in the first state, that the first UT is in a second state in which the first UT has established a Non-Access Stratum protocol (NAS) signaling connection with the MSS-LTE network and an active Radio Resource Control protocol (RRC) connection with the MSS-LTE network;determining, as a result of the first UT being inactive while the first UT is in the second state, that the first UT is in a third state in which the first UT maintains the NAS signaling connection and releases or suspends the RRC connection;receiving a first request to establish a first multimedia session with the first UT;transmitting, in response to receiving the first request and the first UT being in the third state, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) Radio Access Bearer (E-RAB) SETUP REQUEST including a first quality of service (QoS) parameter value indicating the first multimedia session is suitable for a high penetration alerting procedure;receiving the E-RAB SETUP REQUEST; andin response to receiving the E-RAB SETUP REQUEST, and based at least on the first QoS parameter value included in the received E-RAB SETUP REQUEST, transmitting a high penetration alert signal to the first UT. 2. The method of claim 1, further comprising: in response to receiving the E-RAB SETUP REQUEST and before transmitting the high penetration alert signal, transmitting an ordinary paging signal to the first UT. 3. The method of claim 1, wherein the first QoS parameter value is QoS class indicator value or an Allocation and Retention Policy (ARP) value. 4. The method of claim 1, further comprising: determining that a second UT is in the second state;determining, as a result of the second UT being inactive while the second UT is in the second state, that the second UT is in the third state;determining, as a result of the second UT being inactive while the second UT is in the third state, that the second UT is in a fourth state;receiving a first request to establish a second multimedia session with the second UT;transmitting, in response to receiving the first request and the second UT being in the fourth state, a S1AP Paging request including a Paging Priority value indicating the second multimedia session is suitable for a high penetration alerting procedure;receiving the S1AP Paging request; andin response to receiving the S1AP Paging request, and based on at least the Paging Priority value included in the received S1AP Paging request, transmitting a high penetration alert signal to the second UT. 5. The method of claim 1, further comprising: generating, by a PCRF, a Policy and Charging Control (PCC) rule including a QoS parameter value indicating the first multimedia session is suitable for the high penetration alerting procedure,wherein the transmitting a high penetration alert signal to the first UT is further in response to the PCC rule indicating that the first multimedia session is suitable for the high penetration alerting procedure. 6. The method of claim 1, further comprising: retrieving, in response to receiving the first request, user profile data for a user of the first UT; anddetermining that the first multimedia session is suitable for the high penetration alerting procedure based at least on the retrieved user profile data. 7. The method of claim 1, further comprising: selecting one of a plurality of degrees or levels of increased amplitude for the high penetration alert signal relative to an ordinary paging signal;including a second QoS parameter value in the transmitted E-RAB SETUP REQUEST, the second QoS parameter value indicating the selected degree or level; andadjusting an amplitude of the transmitted high penetration alert signal based at least on the second QoS parameter value included in the received E-RAB SETUP REQUEST. 8. The method of claim 1, further comprising: determining, based at least on the first request, that the first multimedia session is for an emergency,wherein the first QoS parameter value included in the transmitted E-RAB SETUP REQUEST is selected in response to the determination that the first multimedia session is for an emergency. 9. The method of claim 1, further comprising: determining that the first UT has frequently required use of high penetration alerting for the first UT to receive paging; andreducing, based on the determination that the first UT has frequently required use of high penetration alerting for the first UT to receive paging, a number of transmissions of ordinary paging signals transmitted to the first UT in response to receiving the E-RAB SETUP REQUEST prior to the transmission of the high penetration alert signal. 10. A Long-Term Evolution (LTE) mobile satellite system (MSS-LTE) communication network comprising: a plurality of processors; anda plurality of non-transitory machine-readable media including instructions which, when executed by the processors, cause the processors to:determine that a first user terminal (UT) is in a first state;determine, as a result of an attach procedure for the first UT to the MSS-LTE while the first UT is in the first state, that the first UT is in a second state in which the first UT has established a Non-Access Stratum protocol (NAS) signaling connection with the MSS-LTE network and an active Radio Resource Control protocol (RRC) connection with the MSS-LTE network;determine, as a result of the first UT being inactive while the first UT is in the second state, that the first UT is in a third state in which the first UT maintains the NAS signaling connection and releases or suspends the RRC connection;receive a first request to establish a first multimedia session with the first UT;transmit, in response to receiving the first request and the first UT being in the third state, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) Radio Access Bearer (E-RAB) SETUP REQUEST including a first quality of service (QoS) parameter value indicating the first multimedia session is suitable for a high penetration alerting procedure;receive the E-RAB SETUP REQUEST; andin response to receiving the E-RAB SETUP REQUEST, and based at least on the first QoS parameter value included in the received E-RAB SETUP REQUEST, transmit a high penetration alert signal to the first UT. 11.
