DETAILED DESCRIPTION
The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. Also, the following detailed description does not limit the invention.
In order to enhance performance, among other things, multi-access edge computing (MEC) (also known as mobile edge computing (MEC)) is being explored in which core network capabilities (e.g., computational, storage, communication links, etc.) are situated at the network edge. MEC networks or other types of end device application or service layer networks (referred to as “application service layer network”) provide an application and/or a service (referred to as an “application service”). The application service may include a monolithic application, a microservice, or another type of configurable architecture of an application service.
With the advent of Fifth Generation (5G) networks and beyond, operators and/or other entities may wish to deploy an anchor node to permit local edge computing, such as a MEC network or another type of application layer network to communicate with a RAN. With limited space to add equipment and complexities associated with how a single data network communicates with multiple operator core networks, there are challenges in creating these connections efficiently.
According to exemplary embodiments, a multi-operator anchor service is described. According to an exemplary embodiment, the multi-operator anchor service may be implemented by a core network device. For example, the core network device may include a user plane function (UPF), a packet date network gateway (PGW), and/or another type of Internet Protocol (IP) or Layer 3 anchor device, as described herein. According to an exemplary embodiment, the core network device may provide connectivity between end devices and application service layer networks of a multi-operator environment. According to an exemplary embodiment, the core network device may monitor and generate charging information pertaining to application service sessions and users associated with different network operators.
In view of the foregoing, the multi-operator anchor service may simplify the development and gain efficiencies in deployments to access application services for users in a multi-operator environment. For example, the core network device that provides the multi-operator anchor service may eliminate each operator deploying their own anchor device and connectivity thereof with radio access networks and other networks, such as core networks and application layer networks.

Multi-operator anchor device 125 may include a network device that provides the multi-operator anchor service, as described herein. Multi-operator anchor device 125 provides a user plane anchor for data sessions between end devices 130 and external network 115/external devices 117 via a multi-operator network, such as access network 105 and/or core network 120/core devices 122. According to an exemplary embodiment, the multi-operator anchor service may provide a registration and attachment service, as described herein. For example, end devices 130 may register and attach to core networks 120 associated with different network operators via multi-operator anchor device 125. According to an exemplary embodiment, the multi-operator anchor service may include a virtual routing and forwarding (VRF) service. For example, multi-operator anchor device 125 may provide virtual routing and forwarding in support of the multi-operator network and messages exchanged among end devices 130, access networks 105, core networks 120, and external networks 115. According to an exemplary embodiment, the multi-operator anchor service includes a charging service for data sessions, as described herein.

According to some exemplary embodiments, end device 130 may include logic that provides the multi-operator anchor service. For example, end device 130 may make determinations as to the transmission of messages to a core network 120 associated with one of the multiple operators or multi-operator anchor device 125. According to some exemplary embodiments, end device 130 may make these determinations based on a type of procedure associated with a message (e.g., an attachment procedure, a handover procedure, a registration procedure, or another type of network procedure) and/or a type of application service being requested, as described herein.
FIG. 2 is a diagram illustrating another exemplary environment 200 in which an exemplary embodiment of the multi-operator anchor service may be implemented. Environment 200 may include a multi-operator environment that includes multiple operator networks.
As illustrated, environment 200 includes end devices 130-1 and 130-2, an operator A RAN 105-1 including access devices 107-1 and an operator B RAN 105-2 including access devices 107-2. As further illustrated, environment 200 includes a MEC network 115 including MEC servers 117, an operator A core network 120-1 including core devices 122-1, an operator B core network 120-2 including core devices 122-2, and an MO anchor device 125.
The number and arrangement of networks and network devices illustrated and described are exemplary. Additionally, the number, arrangement, and type of connections between the devices and between networks are exemplary. Operator A RAN 105-1 and operator B RAN 105-2 may each include an exemplary implementation of access network 105 and access devices 107, as described herein, and be associated with a distinct network operator (e.g., wireless network operator). Similarly, operator A core network 120-1 and operator B core network 120-2 may each include an exemplary implementation of core network 120 and core devices 122, as described herein, and be associated with a distinct network operator or other type of entity. MEC network 115 and MEC servers 117 are exemplary implementations of external network 115 and external devices 117, as describe herein. According to an exemplary embodiment, multi-operator anchor device 125 may implemented be as a UPF and/or a PGW that provides a multi-operator anchor service (illustrated as multi-operator UPF/PGW 125).
FIGS. 3A-3E are diagrams illustrating exemplary processes of exemplary embodiments of the multi-operator anchor service, as described herein. Referring to FIG. 3A, assume end device 130-1 invokes an attachment and/or registration procedure with core network 120-1 via multi-operator UPF/PGW 125. For example, end device 130-1 may transmit an attachment/registration request 302 to multi-operator UPF/PGW 125. In response to receiving the request, multi-operator UPF/PGW 125 may provide a registration and attachment service in conjunction with a virtual routing and forwarding service of the multi-operator anchor service. For example, multi-operator UPF/PGW 125 may read and interpret the message as an attachment/registration request relative to core network 120.
Based on the interpretation of attachment/registration request 302, for example, multi-operator UPF/PGW 125 may select and route attachment/registration request 302 to the appropriate core network 120 among multiple operator core networks (e.g., 120-1, 120-2, etc.). According to an exemplary embodiment, multi-operator UPF/PGW 125 may select the appropriate core network 120 based on an identifier of end device 130 (e.g., a Mobile Station International Subscriber Directory Number (MSISDN), an International Mobile Subscriber Identity (IMSI), a UE identifier, a Subscription Permanent Identifier (SUPI), an International Mobile Equipment Identity (IMEI), a Mobile Equipment Identifier (MEID), a permanent equipment identifier (PEI), a globally unique identifier (GUI), a temporary identifier, or another suitable user and/or end device identifier), a Public Land Mobile Network (PLMN) identifier, a closed subscriber group identifier, and/or a network address (e.g., a Medium Access Control (MAC) address, an Internet Protocol (IP) address, or another type of network address). Additionally, or alternatively, multi-operator UPF/PGW 125 may select the appropriate core network 120 based on a communication link, a communication interface, and/or a port via which attachment/registration request 302 was received. Additionally, or alternatively, multi-operator UPF/PGW 125 may select the appropriate core network 120 based on an identifier and/or a network address associated with access device 105, for example. In this way, multi-operator UPF/PGW 125 may correlate an identifier or another type of data, as described herein, to the appropriate core network 120.
Multi-operator UPF/PGW 125 may include logic that provides routing in a multi-operator environment. For example, multi-operator UPF/PGW 125 may provide virtual routing and forwarding such that traffic of each operator's network may be separated and isolated. Multi-operator UPF/PGW 125 may include one or multiple logical and/or physical interfaces and multiple routing instances which may operate separately. For example, as illustrated, based on the selection, multi-operator UPF/PGW 125 may route 305 attachment/registration request 302 to operator A core network 120-1. Operator A core network 120-1 may perform an attachment/registration procedure 307. As part of the procedure, operator A core network 120-1 may transmit an attachment/registration response 310 to end device 130-1 via multi-operator UPF/PGW 125. According to some exemplary embodiments, although not illustrated, operator A core network 120-1 may provide policy and charging rules to multi-operator UPF/PGW 125 that pertain to end device 130-1.
Referring to FIG. 3B, subsequent to registration with and/or attachment to operator A core network 120-1, end device 130-1 may generate and transmit an application service request 315. For example, application service request 315 may be a request for an application service from MEC network 115. According to other examples, application service request 315 may be a request for an application service hosted by another type of external network 115, as described herein. Multi-operator UPF/PGW 125 may receive application service request 315 via access device 107 of operator A RAN 105-1. Multi-operator UPF/PGW 125 may read and interpret application service request 315. Based on the interpretation, according to an exemplary embodiment, multi-operator UPF/PGW 125 may provide a charging service 320.
As previously mentioned, according to some exemplary embodiments, multi-operator UPF/PGW 125 may obtain policy and charging rules for end device 130-1 prior to receiving application service request 315. However, according to other exemplary embodiments, multi-operator UPF/PGW 125 may invoke a charging service procedure to obtain policy and/or charging rules/information in response to receiving application service request 315. Multi-operator UPF/PGW 125 may determine operator A core network 120-1 to be associated with end device 130-1 based on the virtual forwarding and routing service, as described herein. Based on the determination, the charging service procedure may include generating and transmitting a charging request 322 to operator A core network 120-1. Based on receiving charging request 322, operator A core network 120-1 may perform a charging procedure 324. For example, the charging procedure may include a policy control function (PCF) receiving charging request 322 and identifying policy and/or charging rules pertaining to end device 130-1. The charging procedure may include communication with other core devices 122-1, such as an HSS, a UDM, or the like, which may store subscription information pertaining to end device 130-1. As further illustrated, the charging procedure may include generating and transmitting a charging response 325 to multi-operator UPF/PGW 125. Charging response 325 may include a policy, a rule, and/or a monitoring parameter (e.g., a key performance indicator (KPI), amount of data, duration of session, and/or other data session parameters) pertaining to charging and monitoring of a data session, for example.
According to some exemplary scenarios, as a part of performing charging procedure 324, operator A core network 120-1 may provide end device 130-1 with a portal, graphical user interface, or other mechanism for establishing a charging plan, payment (e.g., using credit card), or another type of subscription and/or charging arrangement. For example, when a current subscription or plan associated with end device 130-1, when present, does not cover or permit access and/or use of the requested application service, operator A core network 120-1 may perform these exemplary steps. In some cases, operator A core network 120-1 may deny access to end device 130-1, and may communicate such denial to multi-operator UPF/PGW 125. According to such case, multi-operator UPF/PGW 125 may deny application service request 315. Otherwise, charging response 325 may include information pertaining to the charging arrangement.
Referring to FIG. 3C, multi-operator UPF/PGW 125 may communicate with MEC network 115 to establish an application service session 330 between end device 130-1 and MEC server 117. Multi-operator UPF/PGW 125 may enforce charging 340 pertaining to the application service session 335. Multi-operator UPF/PGW 125 may monitor and collect data pertaining to the application service session (e.g., KPI, performance metric, quality of service (QoS), amount of data, time period of data session, etc.) based on a requirement from operator A core network 120-1, for example. Multi-operator UPF/PGW 125 may generate charging information (e.g., a charging record) or charging and session information based on the monitoring.
Referring to FIG. 3D, multi-operator UPF/PGW 125 may manage the application service session 345, such as satisfying a performance metric (e.g., latency, bit rate, throughput, error rate, reliability, or other performance indicator) associated with user plane traffic and managing control signaling pertaining to the application service session. As further illustrated, multi-operator UPF/PGW 125 may transmit charging information or charging and session information 350 to operator A core network 120-1.
