Allocation of user equipment identifier
First Claim
1. A method, comprisingmaintaining in a base station a set of identifiers, each identifier of the set being at least temporarily allocatable to a user equipment for identifying the user equipment when the user equipment resides in a cell of the base station;
- connecting a substation to the base station;
extracting from the set of identifiers at least one subset of identifiers;
assigning the subset of identifiers to the substation; and
configuring the substation to respond to a connection establishment request of the user equipment by providing the user equipment with an identifier from the subset of identifiers assigned to the substation and to transmit to the base station information on the connection establishment request and on the identifier provided to the user equipment.

Abstract
A communication system that comprises a base station and a substation connected to the base station. The base station maintains a set of identifiers, each identifier of the set being at least temporarily allocatable to a user equipment for identifying the user equipment when it resides in a cell of the base station. From the set of identifiers of the base station at least one subset of identifiers is extracted, and assigned to the substation. The substation may then respond to a connection establishment request of user equipment by providing it with an identifier from the subset of identifiers assigned to it. The substation also transmits to the base station information on the connection establishment request and on the identifier provided to the user equipment.
