A method for cell selection and/or cell reselection handling includes: performing, by a user equipment, a cell selection and/or cell reselection procedure wherein both a first radio cell and a second radio cell fulfill a cell selection criterion with the first radio cell being prioritized relative to the second radio cell; attempting, by the user equipment, to connect to a public land mobile network using a random access channel of a first base station entity, and failing to connect to the public land mobile network using the random access channel of the first base station entity; and performing, by the user equipment, a modified cell selection and/or cell reselection procedure, under unchanged radio conditions, whereby the user equipment attempts to connect to the public land mobile network using a random access channel of the second base station entity.

A method for communication between network nodes of a mobile communication network includes: transmitting, by a first base station, a first message to a specific network node using a first indirect communication interface; and transmitting, by the specific network node, a second message to a second base station entity using the second indirect communication interface. Via the first and second messages, information related to configuration information content is transparently transmitted from the first base station entity to the second base station entity, via the specific network node of the mobile communication network, using the first and second indirect communication interfaces.

A method for improving overall network performance and/or overall quality of service of a mobile communication network by assigning physical cell identifier information to a plurality of radio cells includes: in a first step and for each of a plurality of coverage area elements of a common radio coverage area, generating a set of handover likelihood information; in a second step, calculating, based on elements of the sets of handover likelihood information, an overlap score value indicative of the overlap between at least one source radio cell and at least one target radio cell; and in a third step, assigning the physical cell identifier information to the at least one source radio cell and/or the at least one target radio cell dependent on the overlap score value.

Overall network performance and/or overall quality of service of a mobile communication network by assigning a physical cell identifier information to a plurality of radio cells

A method for improving overall network performance and/or overall quality of service of user equipments in a mobile communication network includes in a first step, a base station entity, prior to executing a requested handover procedure, requests a user equipment to decode a cell global identifier of the target radio cell; in a second step, subsequent to the first step, the base station entity receives the decoded cell global identifier reported by the user equipment; and in a third step, subsequent to the second step, the base station entity determines which of further radio cells having the target physical cell identifier information and the target center frequency corresponds to the target radio cell, and initiates the handover procedure towards the target radio cell.

Improving overall network performance and/or overall quality of service of user equipments in a mobile communication network

A method for improved communication between network nodes of a mobile communication network includes: establishing a communication interface between first and second base station entities by generating a first instance of the communication interface at the first base station entity and generating a second instance of the communication interface at the second base station; transmitting, from a removal initiating base station entity, a first removal message to a removal responding base station entity, wherein the removal initiating base station entity is one of the first and second base station entities and the removal responding base station entity is the other of the first and second base station entities; receiving, at the removal initiating base station entity, a second removal message from the removal responding base station entity; and disabling the communication interface, wherein disabling the communication interface comprises removing the first and second instances of the communication interface.

A method for transmission of environment-related information between a user equipment and a mobile communication network includes: transmitting measurement configuration information from a mobile communication network to a user equipment; obtaining local network information by conducting a requested measurement; and transmitting the local network information together with at least one other uplink transmission performed by the user equipment to the base station entity by using at least one radio interface of the user equipment.

Enhancing the usage of resources related to the transmission of environment-related information between a user equipment and a mobile communication network

A method for operation of a cellular telecommunications network in an edge region of the radio coverage area of the cellular telecommunications network includes: in a first step, a user equipment receives from the further base station entity information comprising the specific cell identifier, wherein the specific cell identifier as well as additional information related to the further base station entity are transmitted by the user equipment to the serving base station entity; and in a second step, subsequent to the first step, the user equipment, upon reception from the further base station entity of identifier information comprising the specific cell identifier, and based on blacklist information received by the user equipment referring at least to the specific cell identifier, avoids transmitting additional information regarding the further base station entity to the serving base station entity and/or avoids consideration of the further base station entity in a cell-reselection procedure.

A method for improved measurement handling by a user equipment in a multi-Radio Access Technology (RAT) and/or multi-frequency and/or single-frequency radio environment of a public land mobile network includes: transmitting a measurement activation/deactivation information from a serving cell base station to the user equipment, the measurement activation/deactivation information being related to future inter-frequency and/or inter-RAT and/or intra-frequency measurements towards a neighbor cell base station entity to be either activated or set to a non-permanent state.
