Problems solved by technology

In LTE network, compared with 2G and 3G network, the signaling carrying IMSI is encrypted between UE and core, so it cannot be monitored and used as the basis of presence service in RAN

Embodiment Construction

[0031] The concepts of the present invention have particular applicability in cellular communication systems supporting multiple overlapping communication coverage areas, such as communication systems comprising a combination of small cells and macro cells. Furthermore, the inventive concept has applicability in cellular communication systems comprising multiple radio access technologies.

[0032] Those skilled in the art will recognize and appreciate that the details of the described examples are merely illustrative of some embodiments and that the teachings detailed herein are applicable to a variety of alternative arrangements.

[0033] Now refer to figure 1 , Macro-evolved NodeBs (ENodeB or eNodeB or ENB) 101 provide cellular communication services over their respective coverage areas and operate using LTE radio access technology. Macro eNodeBs are a common design. For example, an eNodeB may typically contain information such as operating frequencies and / or identifiers a...

Abstract

A method and apparatus for redirecting a wireless communication unit (113) from a LTE cell to a neighbouring 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.

Description

technical field [0001] The field of the invention relates to network elements, wireless communication systems and methods for operating cellular communication systems, and has particular applicability to providing location presence services in such systems. Background technique [0002] Wireless communication systems such as third generation (3G) mobile telephony standards and technologies are well known. The third generation partnership project (3GPP TM ) (www.3gpp.org) developed Universal Mobile Telecommunications System (UMTS TM ) is an example of such 3G standards and technologies. Third generation wireless communications have been extensively developed to support macro cell mobile phone communications. Such macro cells use high powered base stations (NodeBs in 3GPP parlance) to communicate with wireless communication units within a relatively large geographic coverage area. Typically, a wireless communication unit, or user equipment (UE) as they are often referred t...
