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： 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 presence service can be provided by an access point 101 serving a small cell 100 by rejecting a request for registration from a user equipment 103 after acquiring its IMSI and sending the IMSI to a presence database 105. The user equipment determines if the cell is a presence cell by comparing the cell's location area code (LAC) with LACs stored in a list and looking for a match. It the cell is a presence cell then the user equipment, rather than placing the LAC in a forbidden list, re-tries registration again but only after a pre-set time period of 5-10 minutes has elapsed. This has the advantage that a presence service can be notified of subscribers who linger in a particular area or return to that area at regular intervals.
