METHOD FOR BEARER ESTABLISHMENT IN A RADIO ACCESS NETWORK
First Claim
1. A method for bearer establishment in a radio access network, the method comprising:
- at a system element having an application function;
determining 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;
sending, to an evolved packet core, a request to establish a bearer, wherein the request includes the pre-allocation information, wherein the determining and the sending are performed prior to at least one user equipment in the set of user equipment connecting to the at least one cell identified by the pre-allocation information; and
receiving a response indicating that the bearer was established in the at least one cell.

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.

15. A method for bearer establishment in a radio access network, the method comprising:
-
at an evolved packet core; receiving, from a system element having an application function, a request that includes pre-allocation information used to select a set of cells in the radio access network to which a set of user equipment will connect for exchanging data, wherein the request is for establishing a bearer, wherein the request is received prior to at least one of the user equipment in the set of user equipment connecting to the set of cells; processing the request to establish the bearer in the set of cells; and providing, to the system element, a response to the request, wherein the response indicates that the bearer was established. - View Dependent Claims (16, 17, 18, 19)
