Techniques for packet core network (PCN) gateway selection of collocated gateways are disclosed herein. A mobility management entity (MME) can retrieve charging characteristics (CC) information to determine whether collocated gateway selection is applicable for a UE. When collocated gateways are to be selected, the MME can configure domain name server (DNS) queries in a manner which is adapted for collocated gateway identification. Upon receipt of the DNS query, the DNS can be configured to identify collocated serving gateways (SGWs) which are each collocated with a packet gateway (PGW). The DNS can return identifications of the collocated SGWs to the MME, and the MME can use the identifications of the collocated SGWs to select a collocated SGW and a corresponding collocated PGW for use in connection with the network access for the user equipment.

Systems, methods, and devices are disclosed for reducing the number of emergency call failures in wireless communication networks. More specifically, the present technology includes systems and methods for detecting emergency call failures and identifying packet core network functions (NFs) causing failures in near real-time. A method of operating a wireless communication network includes monitoring data associated with one or more emergency call functions to detect abnormalities in the data indicative of emergency call failures; in response to detecting an abnormality in the data, processing other data associated with one or more other network functions to determine whether one or more corresponding abnormalities are present in the other data; and, in response to determining that at least one corresponding abnormality is present in the other data, generating an alert to indicate that the abnormality exists. The method may be performed, at least in part, by one or more machine learning models.

This facilitates security handling when switching from 5GS to an Advanced Packet Core (EPC). [Solution] In a communication system, the method by the UE encodes a first tracking area update (TAU) request using a first security context associated with a first radio access technology (RAT), the first TAU ​​request includes a first set of information including identifiers mapped to a second RAT associated with a first network entity, which are integrity protected using a first uplink count based on the first security context. A second TAU request includes a first set of information which are integrity protected using a second uplink count. The method also communicates based on the mapped security context, which is based on the first security context and at least one of the first uplink count or the second uplink count.

A device, method and software are presented for a 5G OpenRAN controller. In one embodiment the 5G OpenRAN controller includes an interface for an EPC virtualization stack; an interface for a radio virtualization stack; a software suite executing on the 5G OpenRAN controller; and wherein the 5G OpenRAN controller virtualizes existing cells into a pool of virtualized resources that can be allocated dynamically and virtualizes multiple cores into a pool of resources for multi-technology RANs and presents them as standard interfaces to a packet core.

A spectrum access system (SAS) includes a transceiver that receives information indicating a path loss from an interior location to an exterior location in response to a base station being installed at the interior location. The SAS also includes a processor to determine an aggregate interference level for an incumbent proximate the exterior location based on the path loss. An edge router executes instances of a packet core network. The edge router instantiates containers for a connectivity or digital automation enabler and routes customer network traffic without leaving the customer network. A domain proxy receives a request to allocate carriers to a base station and determines whether a frequency separation between the carriers is larger than a bandwidth allocated to an incumbent. The request is rejected if the frequency separation is less than the bandwidth and granted if the frequency separation is greater than or equal to the bandwidth.

Apparatuses, methods, and systems are disclosed for establishing a connection with a dual registered device. One method includes receiving a first request to establish an internet protocol multimedia subsystem session with a first device, wherein the first device is dual registered to: a first network access supporting 5G core network connectivity; and a second network access supporting evolved packet core network connectivity and circuit switched network connectivity, wherein the first device has connectivity to an internet protocol multimedia subsystem via either the first network access or the second network access. The method includes determining first information corresponding to a network access connectivity selected from the first network access and the second network access through which the first device has internet protocol connectivity with the internet protocol multimedia subsystem. The method includes transmitting a second request to a first network function to retrieve second information.

Technology embodied in a method that includes receiving a first data packet associated with a first IMS session or transaction between a first UE and an IMS over an IP network, and determining, based on information included in the first data packet, that an IP address of the first UE is included in a list of IP addresses stored at the IMS module. The IMS module is configured with the list that represents UEs deemed to receive priority service, and the IP addresses are assigned by a Packet Core Network, to the UEs during set-up of corresponding IMS PDU sessions. The method further includes responsive to determining that the IP address of the first UE is included in the list of IP addresses stored at the IMS module, routing and processing the first data packet over a first set of network resources configured to provide the priority service.

An embodiment of the present invention provides a method, apparatus, and network device for obtaining terminal capabilities. The method includes: obtaining first terminal capability information of a target terminal; performing a merging process on the first terminal capability information and second terminal capability information of the target terminal stored in a storage to obtain merged first target terminal capability information; and sending the first target terminal capability information to an evolved packet core network EPC. In the above solution, the obtained terminal capability information is merged with the stored terminal capability information and then sent to the EPC, so that the query results of terminal capabilities of the same system can be merged and updated, reducing the amount of transmitted information and reducing the transmission delay.

The application belongs to the field of location tracing in wireless communication, and relates to a method and system for tracing the location of voice wireless network in public area wireless network, which comprises the following steps: S1: a user initiates the attachment of an evolved packet core network, a gateway extracts the local domain name, a port number and the physical address of a wireless access point of the user; S2: the user successfully passes the voice wireless network service authentication, the gateway and a fixed network AAA fixed network interact, and the local domain name and the port number are transmitted to the fixed network AAA system; S3: the fixed network AAA system extracts a service port in a line information, and queries the physical address and an installation address through the service port; and S4: the fixed network AAA system returns the physical address and the installation address to the gateway. The application realizes the high-precision positioning of the intelligent terminal user through the above technical scheme.
