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.

Measurement reports from only those wireless communication units (109, 110) included in a preferred user list (107) are used to automatically configure cell parameters such as a pilot channel transmission power level in an open access cell served by an access point (103). The preferred user list (107) may be created by monitoring wireless communication unit behaviour and assigning to the list those units which remain attached to the access point (103) for long periods of time.

A communication system comprising a core network operably coupled to a small base station (HNB) arranged to support wireless communications to a user equipment UE is described. The HNB comprises a control processor being arranged in a first embodiment to: support setting up of an air interface connection with the UE to allow the UE and the core network to exchange messages, e.g. for a Location Update procedure and to receive an instruction from the core network via a core network connection to release the connection to the core network; usually, the HNB would transmit a RRC Connection Release message to the UE; however, the UE utilizes this situation to request and receive UE measurements by using RRC Measurement Control/Report messages and thus delays the initiation of the RRC Connection Release procedure towards the UE; in a second embodiment, the control processor is arranged to autonomously page the UE: thus, the UE establishes a RRC connection for responding to the paging message and the HNB may request receive UE measurements
摘要:
A method for at least one service provider to collect wireless communication unit location related data for multiple mobile network operators, MNOs. The method comprises, at a base station supporting multiple MNOs: broadcasting on a first frequency only a first public land mobile network identifier, PLMN-ID, of a first MNO at a first instant in time for detection by first wireless communication units associated with the first MNO; receiving location related information from the first wireless communication units associated with the first MNO in response to the broadcast first PLMN-ID; broadcasting on a second frequency only a second PLMN-ID of a second MNO, at a second instant in time for detection by second wireless communication units associated with the second MNO; and receiving location related information from the second wireless communication units associated with the second MNO in response to the broadcast second PLMN-ID.
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.

A TAI (Tracking Area Identifier) assigned to a small, ‘presence’ cell (106), which is different from that assigned to a neighbouring cell (101), forces a User Equipment (105) entering the presence cell's coverage area to attempt to register with the presence cell. The presence cell forwards the registration request (which includes the UE's temporary subscriber identity and the identity of the most recently serving Mobility Management Entity) to an additional network node (107) that appears as a Mobility Management Entity to other MMEs in the network. The network node then generates a request for the permanent subscriber identity of the UE and sends it to the most recently serving MME (103). The received permanent identity can be forwarded to a presence analytics server (108) for presence purposes. In some examples, use is made of the relevant ‘Context Request’ or ‘Identification Request’ message and ‘Tracking Area Update’ message or ‘Attach Request’ message to obtain details of the UE despite the fact that it has not completed authentication with the presence cell.
摘要:
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.

The invention facilitates the implementation of clusters of small cells or radio heads or Home Node Bs (HNB) (102, 103, 104) managed by a local standard-Iuh enterprise gateway, connected to a standard release 8/9 HNB-GW. The enterprise gateway sends an HNB Registration Request corresponding to each small cell or radio head that it manages to a Home Node B Gateway over the standard Iuh interface, thereby presenting a single logical interface to the Home Node B Gateway (HNB-GW) that appears to the HNB-GW as a collection of Iuh-standard HNBs. This provides the enterprise gateway with a set of call processing and radio resources that it can implement as it wishes, but using standard messaging to control the HNBGW's view of those resources. A further advantage of the invention is the ability to permit hand-in of a user equipment from a macrocell to a small cell.
