Control channel

transports control information used to control the function of the network element. ("signalling channel", e.g. paging channel, broadcast channel, pilot channel).

Core network, CN

3GPP standard terminology. PLMN architecture is divided into Core Network (CN) and Access Network (AN). Whereas Access Network comprises GERAN (BSS for GSM), UTRAN (RNS) and E-UTRAN, Core Network is logically subdivided into a Circuit Switched (CS) domain, a Packet Switched (PS) domain and an IP Multimedia (IM) subsystem.

Correspondent node

Data network PoA [Point of Attachment]

entity within wireless network or mobility management infrastructure providing access to a data network for a wireless user.

Direct mode

Domain;CS domain, PS domain

3GPP standard terminology. Circuit Switched domain (CS domain) refers to the set of all core network entities offering "circuit switched type of connection" for user traffic and for the related signalling. Dedicated network resources are allocated at connection establishment and released at connection release. Entities specific to the CS domain are: MSC, GMSC, VLR. The Packet Switched domain (PS domain, Packet domain) refers to the set of all core network entities offering "packet switched type of connection" for user traffic and for supporting the related signalling. Transports user information using autonomous concatenation of bits called packets: each packet can be routed independently from the previous one. PS domain includes General Packet Radio Service (GPRS) and Evolved Packet Core (EPC). Entities specific to the PS domain are: SGSN, GGSN, PDN GW, S-GW, MME, SGSN. CS and PS domains also have common network entities: e.g, HSS, HLR

Wireless resource allocation
Definition statement

This place covers:

Allocation of wireless resources or adaptation of assigned wireless resources of an access point or of a regulating authority of a self-organizing network for the purpose of communication with user or terminal; (Semi-) persistent scheduling; Allocation of channels to users.

Semi-persistent scheduling is understood as resource allocation, because the allocation of resources is not changed every transmission frame or slot. Re-allocation, i.e. a modification of an existing allocation plan is included, in case it does not involve handover signalling procedures.

Definition statement

This place covers:

  • User-based networks without hierarchical organisation.
  • Users define network(s), affiliation(s), can elect a regulating authority (master), can act as relaying device on behalf of other users.
  • Affiliation of users to network(s) and user's roles in the network(s) can be dynamically changed.
  • Creation and termination of user-defined networks.
  • Single-hop or multi-hop networks for communication between network nodes having no predetermined connectivity and no pre-defined central control.
  • Responsibilities for establishing, maintaining and controlling the network's organisation are distributed among the nodes dynamically.
  • The nodes are either capable of relaying messages between pairs of nodes not having a direct communication link (multi-hop networks) or they communicate directly without having a specific pre-defined association (single hop).
  • Membership in the ad-hoc network may be dynamic.
  • Interrogation networks are considered self-organizing networks.
  • Master-slave aspects as part of the ad-hoc network.
