A wireless telecommunications method, a computer program product and network nodes are disclosed. The wireless telecommunications network node method comprises on a failure to establish a connection after initiating a RACH procedure, repeatedly transmitting a RACH preamble signature using a defined set of resource blocks of an uplink channel. In this way, when a conventional RACH procedure fails to establish a connection with the network, a modified RACH procedure is instead initiated. This modified RACH procedure transmits a RACH preamble signature repeatedly using a repeating set of resource blocks which are repeatedly allocated from the uplink channel. This enables the RACH preamble signature to be repeatedly transmitted so that the energy from these repeated transmissions may be combined by the network in order to detect the presence of the RACH preamble signature transmitted by network nodes in a poor coverage area such as, for example, an MTC device located in a basement.

A resonator assembly is disclosed. The resonator assembly comprises a resonator having a first resonance post coaxially surrounded by a conductive enclosure defining a cavity, the first resonance post being operable to filter a signal at a first frequency and a second resonance post located within the cavity, the second resonance post being operable to filter a signal at a second frequency. Through this approach it is possible to provide a single device which implements more than one independent resonance within the same cavity volume, allowing to build significantly smaller cavity filters, which avoids the need to provide separate devices, one for each frequency.

A user equipment method, user equipment, a base station method, a base station and computer program products. The user equipment method, comprises: on reception of a trigger instructing modification of an access stratum radio bearer, preventing release of an associated non-access stratum bearer. In this way, when an access stratum or data radio bearer is instructed to be modified (as may occur when security credentials for that bearer need to be updated), the associated non-access stratum bearer may be retained in order to allow a update in security credentials to occur without disrupting communication or losing data.

A user equipment method, user equipment, a base station method, a base station and computer program products are disclosed. The user equipment method, comprises in response to a radio resource control connection re-establishment procedure being initiated when operating in a dual-connectivity mode, retaining configuration information of at least one data bearer utilised in the dual-connectivity mode for subsequent re-use. In this way, rather than losing all the data radio bearer configuration during the RRC connection re-establishment procedure, some of this bearer configuration is retained so that it may be subsequently re-used, thereby improving the speed and efficiency of the RRC connection re-establishment procedure.

A network node method, a network node and a computer program product are disclosed. The network node method is for determining cell identifiers for small cell base stations within a wireless telecommunications network and comprises determining a cell identifier to be allocated to each of a plurality of small cell base stations which minimises reuse of cell identifiers between each small cell base station based on neighbour information obtained by each of the plurality of small cell base stations. In this way, a centralized approach is provided where a network node determines the cell identifiers using neighbour information received from the small cell base stations themselves. This helps to ensure that cell identifiers are allocated based on a more complete understanding of the small cell base stations within the wireless telecommunications network and avoids individual vendors allocating cell identifiers themselves.
