Method for bearer establishment in a radio access network
First Claim
1. A method for bearer establishment in a radio access network (120), the method comprising:
- at a system element (108) having an application function;
determining pre-allocation information used to select at least one cell (140) in the radio access network to which a set of user equipment (132, 134, 136) will connect for exchanging data;
sending, to an evolved packet core (110), a request (216) to establish a bearer (220) for at least one user equipment in the set, wherein the request includes the pre-allocation information, wherein the determining and the sending are performed prior to the at least one user equipment in the set coming within a geographic serving area of the at least one cell identified by the pre-allocation information; and
receiving a response (224) from the evolved packet core (110) indicating that the bearer was established in the at least one cell;
wherein;
the request to establish the bearer comprises a first message sent on a policy definition interface (111) between the system element and a Policy Definition Function (112); and
the first message initiates generation of a second message sent on a policy enforcement interface (113) between the Policy Definition Function and a Policy Enforcement Function (114), wherein the second message includes the pre-allocation information or a translation of the pre-allocation information.

Abstract
Generally speaking, pursuant to the various embodiments, pre-allocation of resources in a RAN of a communication system is performed. A system element having an application function determines, for a set of user equipment (UE), pre-allocation information used to select a set of cells in the RAN to which the set of UE will connect for exchanging data. The element sends a request to establish a bearer to an evolved packet core (EPC), wherein the request includes the pre-allocation information. The determining and sending actions are performed prior to one or more of the UE in the set of UE connecting to the set of cells. The EPC processes the request and returns a response to the system element, which identifies that a bearer for unicast and/or group communications has been established.

14. A method for bearer establishment in a radio access network (120), the method comprising:
-
at an evolved packet core (110); receiving, from a system element (108) having an application function, a request (216) that includes pre-allocation information used to select a set of cells in the radio access network to which at least one user equipment in a set of user equipment will connect for exchanging data, wherein the request is for establishing a bearer (220), wherein the request is received prior to the at least one user equipment (132, 134, 136) in the set of user equipment coming within a geographic serving area of the set of cells; processing the request to establish the bearer in the set of cells; and providing, to the system element, a response (224) to the request, wherein the response indicates that the bearer was established; wherein the request to establish the bearer comprises a request to establish a bearer for group communications, which initiates sianalina between a Policy Enforcement Function in the evolved packet core and a set of eNodeB to establish a group session and to pre-allocate the bearer for aroup communications prior to the at least one user equipment in the set of user equipment coming within the geographic area of the set of eNodeBs, wherein the signaling comprises at least one of a list of cell identifiers, mapping coordinates, location coordinates, an area or location identification, or a route indication for the set of user equipment. - View Dependent Claims (15, 16, 17)

18. An apparatus for bearer establishment in a radio access network comprising:
-
an application server that is configured to; determine pre-allocation information used to select at least one cell in the radio access network to which a set of user equipment will connect for exchanging data; send, to an evolved packet core, a request to establish a bearer for at least one user equipment in the set, wherein the request includes the pre-allocation information, wherein the determining and the sending are performed prior to the at least one user equipment in the set coming within a geographic serving area of the at least one cell identified by the pre-allocation information; and receive a response from the evolved packet core indicating that the bearer was established in the at least one cell; wherein;
the request to establish the bearer comprises a first message sent on a policy definition interface between the system element and a Policy Definition Function; andthe first message initiates generation of a second message sent on a policy enforcement interface between the Policy Definition Function and a Policy Enforcement Function, wherein the second message includes the pre-allocation information or a translation of the pre-allocation information.
