The disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of 5G communications technologies and IoT-related technologies. A method for operating relay UE in a mobile communication system includes transmitting, to a network node connected to the relay UE, a remote UE report message including remote UE information about a remote UE accessing a network via the relay UE, wherein the remote UE information includes IP address information allocated to the remote UE; starting a timer upon transmitting the remote UE report message to the network node; receiving, from the network node, a response message in reply to the remote UE report message; and stopping the timer upon receipt of the response message from the network node. the IP address information includes an IP address and port information of the remote UE in case that IPv4 is used as an address type.

A method for providing individualized communication service includes (1) recognizing a first client being communicatively coupled to a first local communication network, (2) determining an identity of the first client, (3) transporting first data between the first client and a first operator communication network, using the first local communication network in accordance with a first service profile associated with the first client, and (4) transporting the first data using the first operator communication network in accordance with the first service profile.

Systems may establish a Session Initiated Protocol (SIP) session during a Home Subscriber Server (HSS) outage. The systems may include Network Functions (NF) that perform steps for establishing the SIP session and/or bypassing the HSS experiencing the outage. For instance, an Interrogating (I)-Call Session Control Function (CSCF) may modify a terminating message received from a User Equipment (UE) to generate a modified terminating message, and send one or more instances (e.g., forks) of the modified terminating message to one or more candidate Serving (S)-CSCFs. A particular S-CSCF of the candidate S-CSCFs may comprise the registered S-CSCF and may respond to an instance of the modified terminating message. In some embodiments, the I-CSCF may establish the SIP session by sending an instance of the modified terminating message to a designated S-CSCF. The designated S-CSCF may determine which candidate S-CSCF comprises the registered S-CSCF, for instance, by querying the candidate S-CSCFs.

Methods, systems, and devices are described for wireless communication. A wireless device such as an in-vehicle system (IVS) may transmit an emergency call (eCall) message to a third party eCall server using a communication session which may be packet based or circuit based. The eCall message may include session information and telematics data. The third party eCall server may relay the session information and telematics data to a public safety answering point (PSAP). For example, the third party eCall server may generate an automatic text-to-speech message that is transmitted to the PSAP over a public communications network. In some cases, the third party eCall server may transmit a response to the wireless device including metadata based on the telematics data transmitted in the eCall message. The eCall message may also include a call-back number, and the PSAP may contact the wireless device directly using the call-back number.

Systems, methods, and software that perform offline charging. One embodiment comprises a Charging Data Function (CDF) of an Offline Charging System (OFCS). The CDF receives accounting requests for a session from a Charging Trigger Function (CTF), and generates an incomplete Charging Data Record (CDR) for the session based on the accounting requests. The CDF identifies request identifiers (ID) assigned to the accounting requests used to generate the first incomplete CDR, and inserts the request IDs in the incomplete CDR. The CDF determines whether one or more of the accounting requests used to generate the incomplete CDR were indicated as a re-transmitted accounting request by the CTF, and inserts content information for the re-transmitted accounting request(s) in the incomplete CDR.

The invention relates, in particular, to a method for registering at least one public address in an IMS network including a terminal that interacts with a security element. According to the invention, the security element includes an application that invites the user of the terminal, upon the occurrence of an event, to enter a public address, selected by the user, via the man/machine interface of the terminal, the application transmitting the public address, accompanied by at least one identifier of the security element, to a remote network via the terminal such that the remote network associates the public address with the identifier.

A mobile device includes a processor, a transceiver, and a storage maintaining vehicle associations including phone numbers of telematics control units of vehicles. The device is programmed to identify a change in network address of the transceiver; encrypt the changed network address; and send the encrypted network address to the telematics control units using short message service messages addressed to the phone numbers of the telematics control units. A vehicle includes a storage including paired device data having phone numbers and network addresses of mobile devices and a telematics control unit including a firewall and web server. The firewall is programmed to, in response to receipt of a message from one of the phone numbers including a network address of the mobile device, update the storage to indicate the network address as an originating address authorized to use the web server.

Aspects of the subject disclosure may include, for example, a system that manages utilization of mobile subscriber identity information including enabling use of such information by different communication devices. The use of the same mobile subscriber identity information by multiple devices can be based on locations and registration error messages, and other mobile subscriber identity information can be assigned to devices based on the locations. Other embodiments are disclosed.

Systems and methods for verified messaging through the interaction involving a short-range transceiver, such as a contactless card, a client device and a server are presented. Verified messaging may be provided in the context of using a client device to receive a user identifier from the user's short-range transceiver, such as a contactless card, and sending a messaging request with the user identifier to a server, which may look up client device information and compare with data about the client device accompanying the request. Matching received client device information to stored client device data based on a user identifier obtained from a short-range transceiver provides an enhanced ability to verify that the client device corresponds to the user associated with the short-range transceiver.

In a method for accessing a legacy wireless network, a radio access network (RAN) node in the legacy wireless network receives an access message sent by a User Equipment (UE) attempting to access the legacy wireless network. The access message includes mobility management entity (MME) information identifying an MME accessed by the UE in an evolved network. The MME information is added by the UE from a temporary identity (ID) allocated by the MME to a first P-Temporary Mobile Station Identity (P-TMSI) in the access message. The RAN node selects a corresponding Serving GPRS Support Node (SGSN) in the legacy wireless network for the UE according to the first P-TMSI in the access message.
