摘要:
A method and apparatus for redirecting a wireless communication unit (113) from a LTE cell to a neighboring 3G or 2G cell for the purposes of performing a procedure which is available in the 2G or 3G cell but not available in the LTE cell includes the provision of an additional LTE access point (109) within the coverage area of an LTE macrocell. The additional LTE access point (109) is arranged to capture a wireless communication unit (113) which is camped onto the LTE macrocell and redirect it to a 3G/2G cell irrespective of whether or not a better service may be provided in the 2G/3G cell. The invention has application to presence detection where collection of wireless communication units' and subscribers' IDs for such a purpose is possible in 3G and 2G cells but not in LTE cells.
摘要:
“Spoof” paging messages including the TMSI of a user equipment (129) known to be a vicinity are transmitted with a relatively high periodicity in an indoor cluster of presence nodes (113-121) and the node which receives the paging response from the user equipment is recorded, thus giving an indication of presence (and location) with a fine granularity. An additional presence node (125) having a different LAC from the macrolayer (123) is located at the entrance to the indoor cluster so that the TMSI and IMSI of the user equipment can be obtained. The invention can advantageously be employed in a retail store where a fine granularity in tracking subscriber movements around the store is desired. To conserve the user equipment's battery life, spoof paging messages are not sent to those user equipments which enter the vicinity on a regular basis, such as employees of the retail store.
摘要:
An Access Point (105) serving a small cell (202) in a cellular communication system (100) uses the User Equipment intra-frequency Primary Scrambling Code detection mode to detect neighbors inter-frequency by switching its carrier frequency to a frequency on which it is desired to check for neighbors (for a period long enough and/or often enough for it UE to have a reasonable chance of detecting such a neighbor). Received measurements on such neighbor cells (202, 203) may be used to compile a neighbor cell list if no such list has been preconfigured in the Access Point or if network listen results have provided only a limited number of detected neighbor cells.

A method and apparatus for periodically assigning new, unique Location Area Codes to each cell comprising a femto-cell network (100-111) permits a user equipment to perform a re-registration attempt with the same cell after a short period of time has elapsed in cases where an initial attempt to register was rejected. The invention is particularly useful for location presence services as a location presence signal may be generated every time a User Equipment (113) attempts to register on a cell (100) whether or not the attempt was successful.
摘要:
A radio access network element (101) obtains a permanent subscriber identity (IMSI) of a User Equipment (103) in an LTE wireless communication system (100) by sending a “fake” service reject message to a User Equipment which has attempted to attach to a cell (102) in a request for services message which includes its S-TMSI. The reject message may include a cause code which results in the UE attempting to attach again, this time using its IMSI. The fake service reject message may be generated in a an eNode B serving one or more macrocells or a evolved Home Node B serving a small cell.

A network element comprises a signal processor supporting communications between a subscriber unit (UE) and a core network (CN). The signal processor is arranged to: receive a first update request message (location or routing area) from the subscriber unit; forward the first update request message to the core network; receive from the CN a first update accept (or response) message; store at least a part of the accept message content; forward the first update response message to the subscriber unit; receive a second update request from the subscriber unit; create a second update accept (or response) message using the at least part of the stored content; and respond to the subscriber unit second update accept (or response) message direct.

摘要:
A network management system for managing communications in a cellular communication network comprising an access point operably coupled to an access controller. The network management system comprises an access controller configuration logic module arranged to configure the access controller with configuration information. The network management system further comprises an access point configuration logic module arranged to configure the access point with configuration information comprising, at least in part, configuration information intended for the access controller.

A network element (130, 330), for providing access control to a core network (120) of a cellular communication network (100) for a wireless communication unit (150) operating within a communication cell supported by the network element (130, 330), comprises a receiver for receiving a message (425) from the wireless communication unit (150) comprising identity information. The network element further comprises logic (160), operably coupled to the receiver, for determining whether to permit the mobile communication unit (150) access to the core network (120), based at least in part on the received identity information.
