Abstract
Methods and apparatuses for activating a vehicular-capable terminal to connect to a base station and/or road side unit. Accordingly a vehicular-capable terminal which would otherwise be in idle mode can then participate in vehicular communications, if appropriate.
Claims19
1:
- Circuitry for a vehicular-capable terminal for use in a mobile telecommunications system, the mobile telecommunications system comprising a plurality of base stations operable to communicate with the vehicular-capable terminal and wherein at least one base station of the plurality of base stations is configured to operate as a road side unit, wherein the circuitry comprises a controller element and a transceiver element configured to operate together to:
- receive a list of one or more base stations selected from the plurality of base stations;
- upon detection that the vehicular-capable terminal is within range of a first base station, determine based on the list of base stations whether to activate a connection with the first base station;
- and
- upon determining to activate a connection with the first base station, activate the connection with the first base station.
2 more elements
2:
- A base station for use in a mobile telecommunications system, the mobile telecommunications system comprising a plurality of base stations operable to communicate with the vehicular-capable terminal and a vehicular-capable terminal, wherein the base station is one of the plurality of base stations and is configured to operate as a road side unit, the base station comprising a transmitter, a receiver and a controller, wherein the controller is configured to:
- transmit, via the transmitter, a list of one or more base stations selected from the plurality of base stations to the vehicular-capable terminal, wherein the list is for use by the vehicular-capable terminal to determine based on the list of base stations whether to activate a connection with a first base station of the plurality of base stations, upon detection that the vehicular-capable terminal is within range of a first base station.
3:
- Circuitry for a base station for use in a mobile telecommunications system, the mobile telecommunications system comprising a plurality of base stations operable to communicate with the vehicular-capable terminal and a vehicular-capable terminal wherein the base station is one of the plurality of base stations and wherein the circuitry comprises a controller element and a transceiver element configured to operate together to:
- transmit, via the transmitter, a list of one or more base stations selected from the plurality of base stations to the vehicular-capable terminal, wherein the list is for use by the vehicular-capable terminal to determine based on the list of base stations whether to activate a connection with a first base station of the plurality of base stations, upon detection that the vehicular-capable terminal is within range of a first base station.
4:
- The circuitry of claim 1, wherein determining whether to activate a connection with the first base station comprises identifying that the first base station is not on the list of one or more base stations.
5:
- The circuitry of claim 1, wherein
- the determining whether to activate the connection with the first base station comprises identifying that the first base station is on the list of one or more base stations, and
- the one or more base stations are further selected from the at least one base station.
6:
- The circuitry of claim 1, wherein, upon activation of the connection with the first base station, the circuitry is configured to exchange vehicular related data with the first base station.
7:
- The circuitry of claim 1, wherein the vehicular-capable terminal is a vulnerable road user (VRU) terminal.
8:
- The circuitry of claim 1, wherein the circuitry is configured not to activate a connection with a core network portion of the mobile telecommunications system.
9:
- The circuitry of claim 8, wherein upon activation of the connection with the first base station, the circuitry is configured to exchange vehicular related data with the first base station while the terminal is not connected to the core network portion of the mobile telecommunications system.
10:
- The circuitry of claim 1, wherein
- the terminal, upon activation of the connection with the base station, is configured not to activate a connection with an anchor element of a core network portion of the mobile telecommunications system, and
- the anchor element is a mobility manager entity (MME).
11:
- The circuitry of claim 1, wherein,
- upon detection that the vehicular-capable terminal is no longer within range of the first base station, the circuitry is configured to de-activate the connection to the first base station and the vehicular-capable terminal switching to an idle connection mode, and
- the idle connection mode is an idle Radio Resources Control (RRC) mode.
12:
- The circuitry of claim 1, wherein the circuitry is configured to switch to a connected mode, the connected mode being a connected Radio Resources Control (RRC) mode.
13:
- The circuitry of claim 1, wherein the vehicle is configured to receive a list of road side units from one of the plurality of base stations.
14:
- The circuitry of claim 1, wherein, upon activating the connection with the first base station, the first base station is configured to transmit an updated list of one or more base stations.
15:
- The circuitry of claim 1, wherein the list of base stations is comprised in a tracking area list communicated by the mobile telecommunications system to the vehicular-capable terminal.
16:
- The circuitry of claim 1, wherein the list of base stations is comprised in a tracking area list communicated by the mobile telecommunications system to the vehicular-capable terminal.
17:
- The circuitry of claim 1, wherein
- the circuitry is configured to notify a presence of the vehicular-capable terminal to the road side unit,
- in response to being notified of the presence of the vehicular-capable terminal, the road side unit is configured to report the presence of the vehicular-capable terminal to at least another of the plurality of base stations, and
- in response to being reported the presence of the vehicular-capable terminal, the at least another of the plurality of base stations, which has been notified of the presence of the vehicular-capable terminal, is configured to alert the vehicular-capable terminal to wake up.
1 more element
18:
- The circuitry of claim 1, wherein the list includes one or more base stations which the vehicular-capable terminal should not connect to.
19:
- The circuitry of claim 1, wherein the circuitry is configured to determine whether the vehicular-capable terminal is within the range of the first base station.
