Description

RELATED APPLICATIONS

The subject patent application is a continuation of, and claims priority to each of, U.S. patent application Ser. No. 16/782,123, filed Feb. 5, 2020, and entitled “AUTONOMOUS TOPOLOGY MANAGEMENT FOR WIRELESS RADIO USER EQUIPMENT,” which is a continuation of U.S. patent application Ser. No. 15/977,513 (now U.S. Pat. No. 10,595,363), filed May 11, 2018, and entitled “AUTONOMOUS TOPOLOGY MANAGEMENT FOR WIRELESS RADIO USER EQUIPMENT,” the entireties of which priority applications are hereby incorporated by reference herein.

TECHNICAL FIELD

The subject application is related to wireless communication systems, and, for example, to a vehicle-to-everything (V2X) communications.

BACKGROUND

In LTE wireless communication systems, vehicle-to-everything (V2X) generally utilizes the Sidelink interface, alternatively referred to as PC5, to enable V2X communications, including V2V (vehicle-to-vehicle) communications, V21 (vehicle-to-infrastructure) communications, V2P (vehicle-to-pedestrian) communications and V2N (vehicle-to-network) communications. The PC5 interface is built based on a mesh architecture of peer-to-peer device communication. LTE V2X also supports Uu interface (the radio interface between the mobile device and the radio access network) enhancement to assist the PC5 communications.
Existing (e.g., PC5-based) interfaces assume a mesh architecture in which every node is a peer to each other. This approach does not rely on any network infrastructure. However, spectrum efficiency cannot be very high because of the peer-to-peer structure. Another drawback of this mesh architecture is that it is not compatible with infrastructure-based cellular networks that utilize a hierarchical architecture. As a result, a separate spectrum needs to be obtained to deploy a V2X service based on a peer-to-peer mesh network architecture, which is very costly.

DETAILED DESCRIPTION

One or more aspects of the technology described herein are generally directed towards an autonomous topology management scheme that operates to establish a hierarchical structure that includes a local manager within a user equipment network that is part of a wireless network. In general, “autonomous” refers to the ability of a peer-to-peer network to establish the hierarchical structure independent of needing any assistance from the wireless network. In one or more implementations, a group of V2X traffic user equipment (UEs, including vehicle and/or pedestrian terminals and the like) form a group, and negotiate with each other to elect a local manager of the group, wherein the local manager, for example, can communicate information with a wireless network device on behalf the UEs of the group.
In one or more aspects, a voting scheme is described, which in one or more implementations elects a single local manage for the group. In general, if a user equipment of the group is capable of being a local manager based on one or more various criteria, the user equipment nominates itself to be the local manager, via a broadcast self-candidacy notification. If not capable, the user equipment selects (e.g., based on signal strength) and votes for another nominated candidate, e.g., by sending voting data comprising an acknowledgment to that neighbor candidate's candidacy notification, and sending a negative acknowledgment to any other candidate. If two or more UEs in the group are candidates, the voting data (acknowledgment(s) and negative acknowledgment(s)) from other user equipment(s) of the group generally determine the local manager.
It should be understood that any of the examples and terms used herein are non-limiting. For instance, the examples are based on New Radio (NR, sometimes referred to as 5G) communications between a user equipment exemplified as a smartphone or the like and network device; however virtually any communications devices may benefit from the technology described herein, and/or their use in different spectrums may likewise benefit. Notwithstanding, these are non-limiting examples, and any of the embodiments, aspects, concepts, structures, functionalities or examples described herein are non-limiting, and the technology may be used in various ways that provide benefits and advantages in radio communications in general.
In some embodiments the non-limiting term “radio network node” or simply “network node,” “radio network device or simply “network device” is used herein. These terms may be used interchangeably, and refer to any type of network node that serves user equipment and/or connected to other network node or network element or any radio node from where user equipment receives signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, gNodeB, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.
In some embodiments the non-limiting term user equipment (UE) is used. It refers to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of user equipment are target device, device to device (D2D) user equipment, machine type user equipment or user equipment capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc.
Some embodiments are described in particular for 5G new radio systems. The embodiments are however applicable to any radio access technology (RAT) or multi-RAT system where the user equipment operates using multiple carriers, e.g., LTE FDD/TDD, WCMDA/HSPA, GSM/GERAN, Wi Fi, WLAN, WiMax, CDMA2000, etc.
The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the user equipment. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.
Note that the solutions outlined equally applies for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).
FIG. 1 illustrates a wireless communication system 100 comprising one or more UEs 102(1)-102(n) and a network 104 (e.g., representing any network device or set of devices). In order to form a group, in one or more aspects, a user equipment, e.g., 102(1), broadcasts a discovery signal to one or more neighboring UEs, e.g., 102(2)-102(5), so that the user equipment 102(1) can be discovered. At generally the same time, the user equipment 102(1) and the other neighboring UEs 102(2)-102(5) are monitoring for such discovery signals. Note that the other neighboring UEs 102(2)-102(5) may or may not have discovered each other yet, although one or more may have discovered one or more others beforehand, and indeed, a prior group may already exist.
Once discovered, a user equipment, e.g., 102(1), and at least one other user equipment may form a group or join an existing group, which forms a new group. In one or more implementations, for example, the PC5 interface (Sidelink) defined in LTE has standardized discovery signals and a suitable corresponding procedure for broadcasting and discovery, and may be leveraged to form the group. Notwithstanding, any suitable broadcast/discovery technology may be used.
Thus, in the example of FIG. 1, a group 106 is formed, comprising the UEs 102(2)-102(5). In FIG. 1, the user equipment 102(n) is not part of the group, such as because it was not in range of the discovery signals, did not want to participate, and so on. As can be readily appreciated, although the example group 106 comprises the UEs 102(2)-102(5), any practical number (at least two) of UEs can form a group.
Unlike conventional peer-to-peer structures, the group 106 as described herein is formed with the intention of having one user equipment operate as a local manager, and communicate with the network device 104 on behalf of the group, e.g., to relay communications to and from the network device 104. To this end, as further represented in FIG. 1, aspects of the technology described herein include broadcasting candidacy notifications, in which any user equipment can seek to become a local manager of the group 106. In the example of FIG. 1, the user equipment 102(3) and the user equipment 102(5) are broadcasting candidacy notifications to the group.
In general, to determine candidacy qualifications, any user equipment monitors the synchronization signal from any existing local manager, or from the network device 104. If the RSRP (Reference Signal Received Power) that is received is less than a threshold value, the user equipment may volunteer itself to be local manager, although this is likely to be dependent on one or more other criteria, such as battery capabilities, traffic type, hardware capability, or service capability (e.g., environmental sensors fusion capability or platoon navigation).
If a user equipment decides to become a candidate for the local manager, the user equipment notifies the other, neighbor UEs in the group about its candidacy for local manager. Note that the user equipment autonomously selects the radio resource for broadcasting the self-candidacy notification, which is received by other UEs in the group as a “neighbor-candidacy notification.”
As an alternative to an explicit “self-candidacy nomination,” a message may be sent from a user equipment to nominate another, neighbor user equipment to be a local manager. For example, in a situation in which a user equipment cannot itself act as a local manager on its own (e.g., due to limited capabilities), the user can request (by sending an indirect “neighbor-candidacy notification”) for a nearby vehicle (or other user equipment) to become a candidate for local manager, even if the other user equipment is already connected to a different local manager. It is feasible for a user equipment to nominate more than one other user equipment to become candidates.
Regardless of the source of a received neighbor-candidacy notification, the user equipment has a time duration to decide how to respond. In one or more implementations the time duration is an absolute time, such as where the synchronization is achieved by GNSS (Global Navigation Satellite System). This supports a principle in one or more implementations, which is that any user equipment can connect to only one local manager. Within the time duration, a user equipment may ignore any neighbor-candidacy notification, or broadcast its decision on each, e.g., send voting data (e.g., an acknowledgement or negative acknowledgement) in response to the neighbor-candidacy notification.
FIG. 2 represents voting data being sent by in response to the neighbor-candidacy notifications received as a result of the candidacy notifications broadcast in FIG. 1, which made the user equipment 102(3) a candidate for local manager and made the user equipment 102(5) another candidate for local manager. The user equipment 102(1) votes for (sends an acknowledgement identifying) the user equipment 102(3), and votes against (sends a negative acknowledgement identifying) the user equipment 102(5). The user equipment 102(4) votes for (sends an acknowledgement identifying) the user equipment 102(5), and votes against (sends a negative acknowledgement identifying) the user equipment 102(3). The user equipment 102(2) votes for (sends an acknowledgement identifying) the user equipment 102(3), and does not respond to the candidacy notification from the user equipment 102(5), such as because it chose not to, or did not receive the broadcast candidacy notification.
Various rules/criteria evaluation can be used to make a voting decision. Note that the following rules/criteria are only non-limiting examples for one possible voting scheme, and that only some, all, or other/more additional rules/criteria can be used.
For example, the decision whether to ignore can be based on the receiving signal strength of the candidacy notification. If the candidacy notification signal strength is too low, then a negative acknowledgement is sent.
Further, a user equipment can estimate the relative velocity between the candidate and itself (e.g., through Doppler shift estimation). When the relative velocity is larger than a threshold, the user equipment can ignore the candidacy notification (although in an alternative implementation, a negative acknowledgement can be sent).
If a user equipment is already connected to a local manager, then the user equipment can compare the received signal strength from new candidate for local manager. If the new candidate local manager's RSRP is stronger than the existing local manager, (possibly with some margin), then the user equipment sends a negative acknowledgement, with a time indicator on the valid term period of the current local manager, to the new candidate local manager, so that the new candidate local manager can know when the current local manager's term expires. Otherwise, the user equipment sends a negative acknowledgement to the new candidate.
If the user equipment receives multiple neighbor-candidacy notifications, the user equipment can compare the RSRP of each candidate, and only send an acknowledgement to the candidate with the strongest RSRP (and negative acknowledgements to the rest of the candidates). If the user equipment received a candidacy notification (within a time window) after the user equipment had sent acknowledgement to an earlier candidacy notification from another candidate, the user equipment sends a negative acknowledgement to the later candidacy notification.
In another alternative, when sending an acknowledgement/negative acknowledgement vote to a candidate local manager, the user equipment may additionally send an indication of other candidate local managers from which the user equipment has received candidacy notifications, as well as the most recently reported acknowledgement/negative acknowledgement status or total number of “votes” reported to other candidates. This can help distribute voting data knowledge throughout the group, such as when a user equipment cannot communicate with every member of the group. Such knowledge can be used as a tie-breaker/conflict resolution; e.g., when no one user equipment receives enough votes to become a local manager. Example tie-breakers can be to split the group, have a random or pseudo-random selection, have a step-up/back-off selection procedure (e.g., based on relative capabilities) and so on.
With respect to a user equipment that wants to become the local manager, after sending out its self-candidacy notification, the user equipment monitors the voting data (acknowledgement(s)/negative acknowledgement(s)) received from the neighbor UEs for a period of time. If the ratio of acknowledgement over negative acknowledgement is higher than a threshold, the user equipment is elected as new candidate manager for one term (term is defined as a period of time). Otherwise, the user equipment continues to behave as regular user equipment (e.g., the user equipment may connect to an elected local manager), and refrains from sending another candidacy notification for a period of time.
In another alternative, if a candidate receives a local manager nomination request, or indication from a regular user equipment that the candidate is a unique local manager candidate, the candidate may choose to become a local manager even if the received acknowledgement/negative acknowledgement ratio is below the threshold configured limit, to avoid stranding regular UEs without any local manager connectivity. As can be readily appreciated, this can split the group if another local manager has been elected.
In the example of FIG. 3, the group 106 has elected the user equipment 102(3) as the local manager, based on the voting data represented in the example of FIG. 2. Once elected, in general the local manager 102(3) operates as a base-station including, but not limited to, transmitting periodic synchronization signals to surrounding/nearby neighboring UEs, monitoring RACH (random access channel) signals from UEs for access, and so on. For a connected user equipment, the local manager 102(3) schedules radio resources for the user equipment to transmit uplink data or receive unicast downlink data, and for all connected user equipment, schedules radio resources for broadcasting information.
After the term expires, the local manager can broadcast its self-candidacy notification again, (subject to still meeting current capabilities/current state versus self-nomination decision criteria). The connected UEs are able to receive the new candidacy notification and re-vote (send acknowledgements/negative acknowledgements) to the new candidacy notification. Other user equipment, e.g., not in the previous group, may also receive this new candidacy notification and vote with an acknowledgement/negative acknowledgement.
Depending on the votes and the voting scheme, e.g., the ratio of acknowledgements/negative acknowledgements, the previous term-expired local manager may go back to regular user equipment or continue serve as local manager. Additional metrics such as RRM/CSI/CLI measurements may be used to determine whether a local manager should continue in that role, based on interference to other groups or coverage limitations, and so on.
To summarize, FIGS. 4-6 comprise a flow diagram showing some example operations that a user equipment 102 may perform with respect to determining a local manager. Operation 402 represents a user equipment device broadcasting a discovery signal. Operation 404 represents a user equipment device discovering one or more other UEs; note that if none are discovered, the discovery process ends and can be re-tried.
Operation 406 represents a user equipment device forming a group, e.g., a first time group, or a new group formed by joining an existing group. Operation 408 represents monitoring the synchronization signal from any local manager (if a group previously existed) or the network device, as described above.
As also described above, operation 410 represents the user equipment evaluating its own capabilities with respect to its current state versus one or more criteria to determine whether the user equipment is to nominate itself as a candidate for local manager. If not, operation 412 branches to FIG. 5, operation 502 to in general vote and then behave as a regular user equipment; if so, operation 412 branches to operation 602 of FIG. 6. Note that if operating as a regular user equipment, one alternative (operation 414) is to nominate another user equipment as a candidate for local manager.
If not volunteering as a candidate for local manager, operation 502 of FIG. 5 represents waiting for and receiving neighbor candidacy nomination notifications. When the waiting time is done, operation 504 represents evaluating the signal strength of the candidates and selecting the local manager candidate with the best signal strength; note that other selection criteria may be used, e.g., as described above, an existing local manager may be given some margin by which a challenger needs to exceed the existing local manager's signal strength.
Operation 506 represents voting, which as described above can be sending an acknowledgment for the selected candidate and a negative acknowledgment for each other candidate. There may be only one candidate.
Operation 508 represents the user equipment behaving as a regular user equipment, which may include initially connecting to an elected local manager, as well as sending and receiving data communications. The user equipment may continue to monitor the synchronization signal (operation 510), e.g., to decide whether to remain in the group (operation 512). If in the group as managed by the local manager, operation 514 continues the regular user equipment operation by returning to operation 508 until the term expires and the example operations of FIG. 4, from operation 408, are again performed.
If instead the user equipment volunteers as a candidate for local manager, operation 602 of FIG. 6 is performed, which represents notifying (broadcasting to) neighbor UEs in the group about the user equipment's candidacy for local manager. Operation 604 represents waiting for the appropriate duration for the neighbor UEs to vote. Note that in one voting scheme, the self-candidacy notification can be considered a vote for the user equipment that nominated itself.
When the waiting time is done, operation 606 represents evaluating whether the voting data indicates that the user equipment has won the vote and is the local manager. If not, the user equipment returns to FIG. 5, operation 508, to behave as a regular user equipment as described above.
If operation 606 determines that the voting data indicates that the user equipment has won the vote and is the local manager, operation 608 represents operating as the local manager, e.g., acting as a base station, including relaying communications to the network device, broadcasting information to other UEs, and so on, or in other words, act in a relay mode or a local breakout mode, depending on traffic type information. As part of operating as a local manager, the local manager can communicate with the network node to establish the list of user equipment assigned to this local manager, receive the assigned radio resource pool for scheduling the user equipment, schedule the assigned user equipment and so on.
In this example, the local manager operation continues until the term expires (operation 612), at which time the process returns to FIG. 4, operation 410 to (possibly) volunteer again to be the local manager. Note that it is feasible for a local manager to end the term early, such as if conditions change, e.g., as based on evaluation of a metric, in which event the manager can resign and a new local manager can be elected. A local manager also can stop functioning, upon which a new local manager can be elected.
FIG. 7 represents general, example operations of a user equipment 102. Operation 702 represents broadcasting, by a first radio user equipment comprising a processor, first discovery signal data for detection by a second radio user equipment. Operation 704 represents discovering, by the first radio user equipment, second radio user equipment based on second discovery signal data detected from the second radio user equipment. Operation 706 represents communicating, by the first radio user equipment, with the second radio user equipment, to form a group. Operation 708 represents determining, by the first radio user equipment, a local manager of the group, the determining comprising communicating within the group.
Determining the local manager of the group can comprise receiving a neighbor-candidacy notification that nominates a neighboring radio user equipment of the group as a candidate to be the local manager of the group, and sending, within a time duration, voting data in response to the receiving the neighbor-candidacy notification. Sending the voting data can comprise sending an acknowledgement or a negative acknowledgement in response to the neighbor-candidacy notification.

Sending the voting data can comprise sending, in response to the receiving the at least two neighbor-candidacy notifications, an acknowledgement identifying the selected candidate, and respective negative acknowledgements with respect to other neighbor-candidacy notifications relating to ones of the at least two corresponding radio UEs other than the selected candidate.
Communicating within the group can comprise broadcasting a self-candidacy notification that volunteers the first radio user equipment as a candidate to be the local manager of the group. Determining the local manager of the group further can comprise monitoring, within a time duration, voting data received from the second radio user equipment in response to the broadcasting the self-candidacy notification, determining, based on the voting data, that the group elects the first radio user equipment to be the local manager of the group, and operating the first radio user equipment as the local manager, comprising relaying information received from the group to a radio network device.

Determining the local manager of the group can comprise receiving candidate nomination data corresponding to at least two UEs of the group, and selecting a selected candidate from the at least two UEs, and communicating the voting data can comprise sending a vote in favor of the selected candidate.
Determining the local manager of the group can comprise broadcasting a self-candidacy notification that volunteers the radio user equipment device as a candidate to be the local manager of the group, evaluating voting data communicated within the group, determining, based on the voting data, that the group elects the radio user equipment device to be the local manager of the group, and operating the radio user equipment device as the local manager for a term, which can comprise relaying information received from the group to a radio network device. The self-candidacy notification can be a first self-candidacy notification, and the operations can comprise, upon expiration of the term, broadcasting a second self-candidacy notification that volunteers the radio user equipment device as the candidate to again be the local manager of the group.
The operations can comprise, within the term, evaluating a metric to determine whether to resign as the local manager prior to expiration of the term.

FIG. 8 represents general, example operations such as corresponding to executable instructions in a machine-readable storage medium, that, when executed by a processor of a radio user equipment, facilitate performance of the operations. The operations can comprise communicating with neighboring radio UEs to form a group comprising the radio user equipment and the neighboring radio UEs (operation 902), and broadcasting a self-candidacy notification that volunteers the radio user equipment as a candidate to be a local manager of the group (operation 904). Further operations can comprise receiving voting data corresponding to the self-candidacy notification (operation 906) and evaluating whether the voting data has elected the radio user equipment to be the local manager of the group (operation 908).
Aspects can comprise, receiving a neighbor-candidacy notification that nominates a neighboring radio user equipment of the neighboring radio UEs as a candidate to be the local manager of the group, and sending, within a time duration, the voting data in response to the receiving the neighbor-candidacy notification.
Evaluating whether the voting data has elected the radio user equipment to be the local manager of the group can comprise comparing a ratio of positive votes of the voting data to negative votes of the voting data with a threshold ratio, and in response to the ratio of the positive votes to the negative votes being determined to exceed the threshold ratio, operating the radio user equipment as the local manager for a term, which can comprise relaying information received from the group to a radio network device relating to the radio user equipment operating as the local manager.
The self-candidacy notification can be first self-candidacy notification, and evaluating whether the voting data has elected the radio user equipment to be the local manager of the group can comprise comparing a ratio of positive votes of the voting data to negative votes of the voting data with a threshold ratio, and in response to the ratio of the positive votes to the negative votes being determined to be below the threshold ratio, refraining from sending a second self-candidacy notification for a period of time.
As can be seen, a user equipment can be autonomously elected by other UEs in a group to be a local manager, achieving various advantages. Advantages include allowing hardware sharing between a regular cellular network and the V2X or D2D (device-to-device) network. The same node can serve as a relay node for a cellular network as well as a V2X local manager. Further, by having a UE elected to operate as a local manager, the peer-to-peer mesh network is in general converted to a hierarchical architecture, because local manager can schedule resources for UEs that are served by it under a standalone or non-standalone network deployment. The spectral efficiency is much better than that of a fully mesh network, and allows greater network control of licensed spectrum. Still further, the technology described herein allows the introduction of mobile relays with existing infrastructure-based IAB nodes under a common architecture and resource allocation framework. The technology allows spectrum sharing between regular cellular networks and V2X services; the same spectrum band may be reused by V2X service or regular cellular traffic. The technology thus provides for an autonomous spectrum utilization technology.

A processor may also be implemented as a combination of computing processing units.
In the subject specification, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory.
As used in this application, the terms “component,” “system,” “platform,” “layer,” “selector,” “interface,” and the like are intended to refer to a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution. As an example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration and not limitation, both an application running on a server and the server can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media, device readable storage devices, or machine readable media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that confers at least in part the functionality of the electronic components.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
Moreover, terms like “user equipment (UE),” “mobile station,” “mobile,” subscriber station,” “subscriber equipment,” “access terminal,” “terminal,” “handset,” and similar terminology, refer to a wireless device utilized by a subscriber or user of a wireless communication service to receive or convey data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream.

Additionally, the terms “core-network”, “core”, “core carrier network”, “carrier-side”, or similar terms can refer to components of a telecommunications network that typically provides some or all of aggregation, authentication, call control and switching, charging, service invocation, or gateways. Aggregation can refer to the highest level of aggregation in a service provider network wherein the next level in the hierarchy under the core nodes is the distribution networks and then the edge networks. UEs do not normally connect directly to the core networks of a large service provider but can be routed to the core by way of a switch or radio area network. Authentication can refer to determinations regarding whether the user requesting a service from the telecom network is authorized to do so within this network or not. Call control and switching can refer determinations related to the future course of a call stream across carrier equipment based on the call signal processing. Charging can be related to the collation and processing of charging data generated by various network nodes. Two common types of charging mechanisms found in present day networks can be prepaid charging and postpaid charging. Service invocation can occur based on some explicit action (e.g., call transfer) or implicitly (e.g., call waiting). It is to be noted that service “execution” may or may not be a core network functionality as third party network/nodes may take part in actual service execution. A gateway can be present in the core network to access other networks. Gateway functionality can be dependent on the type of the interface with another network.
Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” “prosumer,” “agent,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities or automated components (e.g., supported through artificial intelligence, as through a capacity to make inferences based on complex mathematical formalisms), that can provide simulated vision, sound recognition and so forth.
Aspects, features, or advantages of the subject matter can be exploited in substantially any, or any, wired, broadcast, wireless telecommunication, radio technology or network, or combinations thereof.
