Abstract

A method and apparatus for providing connectivity with a public communication services network (204) for a mobile terminal (200). A temporary connectivity identity and associated security parameters are obtained from the network (2:1) and loaded into the mobile terminal from a connectivity providing unit (202) over a local communication link (2:2). When the mobile terminal (2:3) later sends an access request to the network including the temporary connectivity identity, the mobile terminal is registered with the network based on the temporary connectivity identity and associated security parameters. If the network can validate the temporary connectivity identity by means of the associated security parameters (2:5), a connection can be set up with the mobile terminal (2:6) for communication services in the network.

Claims

1. A method of providing connectivity with a public communication services network for a mobile terminal, comprising the following steps:

obtaining, at a connectivity providing unit, a temporary connectivity identity and associated security parameters from the network, wherein the temporary connectivity identity and associated security parameters are unknown to the mobile terminal; and

loading the temporary connectivity identity and associated security parameters into the mobile terminal from the connectivity providing unit over a local communication link, thereby enabling the mobile terminal to register with the network based on said temporary connectivity identity and associated security parameters, in order to set up a connection with the network for communication services,

wherein loading the temporary connectivity identity and associated security parameters further enables the mobile terminal to transfer a remaining connectivity amount from said terminal to another mobile terminal.

2. A method according to claim 1, wherein the local communication link is any one of:

a wireless Infrared link, a wireless Bluetooth link, a wireless near field communication (NFC) link, or a wired link.

3. A method according to claim 1, wherein the temporary connectivity identity is validated at the network during said registration by receiving at least a part of the associated security parameters from the terminal and comparing them with corresponding security parameters stored in the network.

4. A method according to claim 3, wherein the temporary connectivity identity is validated when the received parameters and the stored parameters are equal or correspond otherwise in a predetermined manner.

5. A method according to claim 1, wherein the temporary connectivity identity is valid for a predetermined amount of connectivity including at least one of:

call/session time, connectivity lifetime, and amount of data/bandwidth.

6. A method according to claim 1, wherein the mobile terminal is an M2M module receiving the temporary connectivity identity and associated security parameters over the local communication link from an enterprise server, wherein the temporary connectivity identity and associated security parameters are unknown to the M2M module.

7. A method according to claim 1, wherein one or more protection keys are also loaded into the mobile terminal over the local communication link, to be used by the terminal to protect the communication when a connection has been established with the network, wherein the one or more protection keys are unknown to the mobile terminal.

8. A method of providing connectivity with a public communication services network for a mobile terminal, comprising the following steps:

obtaining, at a connectivity providing unit, a temporary connectivity identity and associated security parameters from the network, wherein the temporary connectivity identity and associated security parameters are unknown to the mobile terminal; and

loading the temporary connectivity identity and associated security parameters into the mobile terminal from the connectivity providing unit over a local communication link, thereby enabling the mobile terminal to register with the network based on said temporary connectivity identity and associated security parameters, in order to set up a connection with the network for communication services,

wherein the connectivity can be renewed by loading an updated temporary connectivity identity and associated security parameters into the terminal over the network, wherein the updated temporary connectivity identity and associated security parameters are unknown to the mobile terminal.

9. A mobile terminal adapted to obtain connectivity with a public communication services network comprising:

a data transfer unit adapted to receive a temporary connectivity identity and associated security parameters from a connectivity providing unit over a local communication link, wherein the temporary connectivity identity and associated security parameters are unknown to the mobile terminal and the connectivity providing unit obtained the temporary connectivity identity and associated security parameters from the network, and

a mobile access unit adapted to register with the network based on said temporary connectivity identity and associated security parameters, in order to set up a connection with the network for communication services,

wherein the data transfer unit is further adapted to transfer a remaining connectivity amount to another mobile terminal.

10. A mobile terminal according to claim 9, wherein the local communication link is any one of:

a wireless Infrared link, a wireless Bluetooth link, a wireless near field communication (NFC) link, or a wired link.

11. A mobile terminal according to claim 9 adapted to use said temporary, connectivity identity and associated, security parameters to obtain connectivity with at least one of:

a mobile access network, a wireless local area network (WLAN) and an Internet Protocol Multimedia Subsystem (IMS) network.

12. A mobile terminal according to claim 9, being an M2M module adapted to receive the temporary connectivity identity and associated security parameters over the local communication link from an enterprise server acting as said connectivity providing unit, wherein the temporary connectivity identity and associated security parameters are unknown to the M2M module.
