Definitions
- the present invention relates to telecommunications and, more particularly, to mobile telecommunications terminals and utilization of network services.
- Multimode terminals are getting more and more popular. Multimode terminals are capable of operating on different system modes (using different radio access technologies and/or able to attach to different core networks). Examples of different system modes are GERAN, WCDMA, TDMA, AMPS, CDMA 2000, WLAN, Bluetooth etc. Multimode networks may support different types of interworking between the system modes supported by the terminal.
- the terminal already provides some information about its capability in different system modes, making the network aware which services the terminal can support in different system modes.
- An example is a GERAN terminal indicating its capabilities; in addition to the capabilities for GERAN access technology, also if it supports WCDMA and/or CDMA 2000 radio access technologies.
- the terminal may have quite different support for services depending on the serving system mode. For example, simultaneous packet and circuit switched service is only possible if both the GERAN network and terminal support dual transfer mode (DTM) while this service is always supported by a GERAN/UTRAN dual mode terminal when served by UTRAN.
- DTM dual transfer mode
- the circuit switched data rate is limited to 9.6 kbit/s for GERAN access while a higher data rate is likely available through WCDMA and an even higher data rate through WLAN.
- GERAN again might support a location service when any of the other modes supported by the multimode terminal do not support this service.
- the terminal requests a service the request is limited to the services supported by the terminal in the currently serving system mode, additional restrictions may be set if the network indicates non-support for some specific network capabilities.
- 3 GPP standardisation different vendors are proposing different ways to solve specific problems where GERAN capabilities are not enough to support a service and thus inter-system change from GERAN to UTRAN is proposed.
- 3GPP TSG-SA WG1 #21 proposes to allow a UE that has CS multimedia capability and that is camping on a GERAN cell but is also within UTRAN coverage to setup a CS multimedia service using a UDI 64 kbit/s bearer in UTRAN.
- 3GPP TSG-SA2 #33 (also June 7-11, 2003) which introduces a proposal for a new procedure for dual CN connection where a UMTS/GSM terminal roaming in GSM in the neighbourhood of UTRAN coverage is allowed to request a dual CN connection to the BSS, even if the MS is not Class A or if DTM is not supported by the MS and/or the BSS, in order to indicate that a handover or a cell change order to UTRAN should be favoured by the BSS.
- Still another example is given in the Finnish patent FI 105309B where the mobile station is aware of the different services supported by different available PLMNs and where the mobile stations selects the PLMN according to the requested service.
- the disadvantage of these solutions is that the mobile station awareness of the services available from different PLMNs cannot be easily arranged. Also the support of services by different PLMNs may not only depend on the capabilities of the PLMN but also e.g. on the load of the networks and then the support of a specific service may be time dependent. Also the service availability may be location dependent e.g. as a function of the capabilities of the serving cell. Also the disadvantage is the need to have service/content based preference lists either in terminal or in network.
- the optimum PLMN cannot be selected for mobile terminated services in which case the mobile station would not be aware of the service in advance and then cannot select the appropriate PLMN in advance and the service request would be rejected already by the PLMN where the mobile station is attached at the time of the service establishment attempt.
- the prior art does not provide a solution for a fully flexible service request in respect to the terminal and the network capabilities in different modes.
- Figure 1 shows a multimode system consisting of a multimode terminal, a number of multimode radio access networks and at least one core network.
- Figure 2 shows a flow diagram where the multimode terminal is attached to access network A and the service X is requested.
- the generic problem solved is the generic case where a multimode terminal is served by one system and the terminal supports a service that is not supported by the serving system, but likely would be supported by another system (supported by the multimode terminal with the other system's coverage available).
- a GERAN/UTRAN dual mode terminal cannot request a specific service that it supports only in the UTRAN mode, when it is served by a GERAN network.
- the invention is that a generic service request signalling is defined where a multimode terminal is allowed to request any service that it supports in any of the modes (e.g., access technology like GERAN / UTRAN / CDMA2000 / BlueTooth / WLAN / ...) supported by the terminal.
- the network may then decide to move the terminal to other system if possible and necessary in order to establish the service.
- the terminal capability indication for each system mode mostly exists already.
- the advantages of the invention are that terminal could start the service regardless the serving system capabilities and the full control is left to the network.
- the terminal would not need to scan the available modes and reselect the system that supports requested service.
- a multimode terminal may support a wide range of services where some specific services are not supported by the mobile in all system modes and some specific services may not be requested from the serving system, it is possible that the terminal (user) does not reach the service it would be able to support, and a service that would be available at the current terminal location through other system modes.
- This problem can be solved by a generic service request procedure that allows the terminal to request any of the services it supports, in any of the system modes it supports, through the current serving system.
- This generic service request can be implemented in several different ways. Normally the network should indicate support for generic service requests in order to avoid compatibility problems for new terminals in legacy networks.
- the terminal may: - Use existing signalling messages defined for the serving system, but with service request parameters that exceed the terminal capabilities in the serving system mode.
- An example being 64 kbit/s circuit switched data that is supported by GERAN but may not be supported by the terminal in GERAN mode.
- the network may then decide to hand over the dual mode terminal to be served by the UTRAN system (when UTRAN coverage and capacity is available locally), and the requested service may then be established through UTRAN.
- the network may deny this service and the network may then negotiate a service on the currently service system that would be supported both by the terminal and network and would be considered acceptable by the terminal.
- a specific signalling container may be built allowing the serving network to direct the terminal service request to one or more other systems.
- an identifier is added to each service request so that the serving system is able to direct each particular service request container only to the corresponding system.
- all parallel service request containers are sent to each other systems and the other systems identify which container carries a service request for itself.
- the terminal builds the service request in a way that is understood by each of the other systems for which the request shall be intended.
- the serving system then does not need to understand in detail any of the terminal capabilities on other systems, it is sufficient that the service request is transferred to the other system and interpreted locally. If the other system is able to serve terminal with the requested service, the terminal would be moved to be served by this system and the requested service would be established there.
- the target system responds with a handover command or a network controlled cell reselection order that makes the terminal to move to the desired system.
- the serving system capability may be extended so that it is able to decode also service requests for services that are not supported by it (not supported at all by the system mode of the serving system or just not implemented by the serving system). This allows a first decision locally by the serving system on the terminal service request.
- the serving system may initiate a handover request (or similar) towards another system or it may directly decide to offer an alternative service that is supported both by the terminal and the current serving system and which it expects to be adequate for the concerned terminal.
- a terminal based system mode selection has several serious disadvantages. Examples of the disadvantages are that: The terminal is not in advance aware which service is best supported by each alternative system. - The terminal is not aware of the load of the alternative system, and then it may be that the alternative system is not at all able to serve the terminal, even with a lower quality of service, while the original system could have been able to serve the terminal with a compromise on quality of service. - System mode changes generate normally significant signalling load that should be avoided when possible. System mode changes normally result to short gaps where the MS is unreachable from any of the locally available systems.
- the terminal operates on the system where a multimode network has put the terminal with different network and cell reselection parameters.
- the terminal should continue signalling through the serving system as normally and the control for system selection should be left for the multimode network.
- the solution to maintain full control at the multimode network while still making it possible for the terminal to be served with a service it wants and which it only supports on a non-serving system mode, or that is only supported by a non- serving system can be reached by a generic service request procedure that allows the terminal to request a service that it supports under any of the supported system modes, and the generic service request can be sent to the serving network, at lest if indicated being allowed by the serving network.
- Figure 1 is an example of a possible multimode system; this invention is not limited to this example case only.
- the multimode terminal supports all the access networks but is attached to one of the access networks based on cell selection criteria. Different access networks may have different set of services supported as well as the multimode terminal may support different set of services which may not be aligned with supported services in the access networks.
- possible access networks could be GSM/EDGE, WCDMA, CDMA2000, WLAN, BT, etc.
- the flow diagram of figure 2 shows that the requested service is established in the current access network or in alternative access network based on the multimode terminal and the access network capabilities in different modes. Similar flow diagrams are valid if the multimode terminal is attached to other access networks.
- the multimode terminal is first switched on (1).
- the multimode terminal selects (2) and attaches (3) to one of multiple available access networks, in this example the multimode terminal selects access network A.
- Service X is then requested on access network A (4), where the service X is supported by the multimode terminal in at least one of the multiple modes supported by the multimode terminal and where the service is requested independently of the support for that service by access network A or the multimode terminal in the mode supported by access network A.
- the serving network decides (5) either to establish the service in the current mode (6) or decides to move the multimode terminal to another access network. If the service can be established at access network B (7), the serving network requests a handover to access network B (8), the terminal is handed over to access network B (9) and the service is established (10).
