Abstract

One aspect of the disclosure relates to a method for handling a service request from a requesting entity in a telecommunications network. A first service request for a particular service is received from the requesting entity. A sequence identifier is assigned to the requesting entity from which the first service request is received. The first service request is rejected by sending a reject message to the requesting entity and the assigned sequence identifier is also communicated to the requesting entity. At some later time, the sequence identifier is transmitted (e.g. broadcasted) in the telecommunications network in order. A second service request for the particular service is then received from the requesting entity and the serving entity now allows the request for the service.

First claim

The invention claimed is:

1. A method for handling a service request from a requesting entity in a telecommunications network, said method comprising:
receiving, from said requesting entity, a first service request requesting a particular service from a serving entity;
assigning a sequence identifier to said requesting entity from which said first service request is received;
rejecting said first service request by sending a reject message to said requesting entity;
informing said requesting entity of said sequence identifier;
transmitting said sequence identifier in said telecommunications network to said requesting entity after informing said requesting entity of said sequence identifier;
receiving a second service request for said particular service from said requesting entity in response to transmitting said sequence identifier in said telecommunications network; and
allowing said second service request from said requesting entity for said particular service.

2. The method according to claim 1 , further comprising:
detecting congestion in said telecommunications network; and
assigning said sequence identifier and rejecting said first service request in response to detecting congestion in said telecommunications network.

3. The method according to claim 1 , wherein said assigned sequence identifier is included in said reject message.

4. The method according to claim 1 , wherein transmitting said sequence identifier comprises broadcasting said sequence identifier in said telecommunications network.

5. The method according to claim 1 , further comprising:
receiving said sequence identifier in said second service request; and
verifying whether said sequence identifier corresponds to said requesting entity.

6. The method according to claim 1 , further comprising linking said sequence identifier to at least one of said requesting entity or said particular service.

7. The method according to claim 1 , further comprising:
starting a timer after informing said requesting entity of said sequence identifier; and
transmitting at least one further sequence identifier assigned to a further requesting entity after expiry of said timer.

8. The method according to claim 1 , further comprising:
defining a plurality of queues, each queue comprising one or more requesting entities; and
assigning said sequence identifier of said requesting entity to one of said plurality of queues.

9. The method according to claim 1 , further comprising:
transmitting a plurality or range of sequence identifiers assigned to a plurality of requesting entities in said telecommunications network;
receiving one or more second service requests for said particular service from at least one of said plurality of requesting entities; and
allowing said one or more second service requests from said at least one of said plurality of requesting entities for said particular service.

10. The method according to claim 1 , further comprising communicating sequence information of said requesting entity from a previous serving entity to a next serving entity.

11. A system for handling a service request in a telecommunications network, said system comprising:
a serving GPRS support node (SGSN), wherein the SGSN is configured to:
receive, from a requesting entity, a first service request requesting a particular service from said SGSN;
assign a sequence identifier to said requesting entity from which said first service request is received;
reject said first service request by sending a reject message to said requesting entity;
inform said requesting entity of said assigned sequence identifier;
transmit said sequence identifier in said telecommunications network to said requesting entity after informing said requesting entity of said assigned sequence identifier;
receive a second service request for said particular service from said requesting entity in response to transmitting said sequence identifier in said telecommunications network; and
allow said second service request from said requesting entity for said particular service.

12. A method for requesting a service from a service entity in a telecommunications network, said method comprising:
transmitting a first service request to said telecommunications network for a particular service;
receiving a reject message in response to transmitting said first service request;
receiving and storing a sequence identifier;
receiving, after storing said sequence identifier, said sequence identifier;
transmitting a second service request to said telecommunications network; and
using said particular service triggered by said second service request.

13. The method according to claim 12 , wherein said assigned sequence identifier is included in said reject message.

14. The method according to claim 12 , wherein receiving, after storing said sequence identifier, said sequence identifier comprises receiving said sequence identifier on a broadcast channel in said telecommunications network.

15. The method according to claim 12 , further comprising transmitting said assigned sequence identifier in said second service request.

16. The method according to claim 12 , further comprising:
detecting a change regarding requesting services from a previous serving entity to a next serving entity, wherein said sequence identifier relates to said previous serving entity;
disregarding said sequence identifier and transmitting said first service request to said next serving entity; and
receiving and storing a new sequence identifier assigned by said next serving entity.

17. A system for requesting a service to a serving entity in a telecommunications network, said system comprising:
a mobile station, wherein the mobile station is configured to:
transmit a first service request to said telecommunications network for a particular service;
receive a reject message in response to transmitting said first service request;
receive and store a sequence identifier;
receive, after storing said sequence identifier, said sequence identifier;
transmit a second service request to said telecommunications network; and
use said particular service triggered by said second service request.

18. The system according to claim 17 , wherein said mobile station is further configured to facilitate linking said sequence identifier to at least one of said mobile station and said particular service in said telecommunications network.

19. A system for requesting a service to a serving entity in a telecommunications network, said system comprising:
a network element, wherein the network element is configured to:
transmit a first service request to said telecommunications network for a particular service;
receive a reject message in response to transmitting said first service request;
receive and store a sequence identifier;
receive, after storing said sequence identifier, said sequence identifier;
transmit a second service request to said telecommunications network; and
use said particular service triggered by said second service request.

20. The system of claim 19 , wherein the network element is selected from the group consisting of a base station, an (e)NodeB, a remote network controller (RNC), a serving General Packet Radio Service (GPRS) support node (SGSN), and a mobility management entity (MME).

21. A system for handling a service request in a telecommunications network, said system comprising:
a network element, wherein the network element is configured to:
receive, from a
