摘要:
A telecommunication system including a mobile station, and means for a mobile station to receive voice-over Internet Protocol (VoIP) calls when it is roaming away from a home network, comprising: means for informing a serving GGSN of the International Mobile subscriber Identity (IMSI) of the called mobile station, and means for enabling a local VoIP control server to map a called MSISDN number to the IMSI number.

In the GPRS when a MS moves from a former routing area to a new routing area, a method of supporting mobile Internet protocol characterized in that on receipt of a routing area update message from the MS, a mobile Internet protocol agent advertisement is sent only to that MS. The move may be inter-SGN or intra-SGN or may involve a change of RNC. The method allows efficient use of radio resources.

A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

In handover in a wireless telecommunications network, dummy packets, or data packets with an indicator bit, are transmitted from a gateway node MME/SAE GW 4 to a source node eNB 2 when there is no more data being sent to the source node 2. The source node 2 forwards them to a target node eNB 3. When the target node eNB 3 detects the indictors, it knows that there is no more data awaiting to be received from the source node 2 and it can continue with data sent from the SAE GW to it instead.

In a telecommunications system, such as E-UTRAN, a User Equipment 6 is connected to a base station eNB 8 by an early radio bearer, which is established using preset values stored at the UE 6 and at the eNB 8. This enables data to be transferred over the radio link prior to formal establishment of a radio bearer between the UE 6 and the eNB 8.

An example of the present invention is a method of transmitting encrypted user data to a mobile terminal in a wireless telecommunications network. The method comprises sending to the mobile terminal a data packet. The data packet comprises both an identifier of encryption information to used in recovering encrypted user data, and user data encrypted using said encryption information.

In handover in a wireless telecommunications network, dummy packets, or data packets with a last used sequence number indicator are transmitted from a source node eNB 2 to a target node 3. When the target node eNB 3 detects the information, it knows the sequence of data packets being received from the source node eNB 2 and which is the last one and its sequence number. Thus, data packets may be suitable ordered for delivery to a mobile terminal UE 1.
摘要:
According to an aspect of the invention, a method for handover of a mobile terminal from a source node to a target node in a wireless telecommunications network includes the steps of making data forwarding of fresh data optional irrespective of the RLC mode, which may involve RLC-UM or RLC-AM bearers.The method may include providing an explicit instruction to the mobile terminal for each bearer on whether a bearer is subject to data forwarding or not. This may then be used by the mobile terminal to handle the buffered packets and PDCP SNs.
摘要:
The present invention provides methods involving at least one mobile unit configured to receive wireless connectivity using first and second wireless communication systems that operate according to first and second radio interface technologies, respectively. The first and second radio interface technologies are different. The method may include determining, in response to the mobile unit handing off from the first to the second wireless communication system, session establishment information for the second wireless communication system based on session establishment information associated with the first wireless communication system.
