Description
METHODS AND ARRANGEMENTS IN A COMMUNICATION NETWORK SYSTEM
TECHNICAL FIELD
The present invention relates to methods, a communication node and a user equipment in a communication network system and, more particular, to a communication network node and a user equipment allowing for minimizing signalling between two communication network nodes as well as methods for such minimization.
BACKGROUND In a communication network system, such as the evolved Universal Terrestrial Radio Access Network (eUTRAN) system, specified by the 3rd Generation Partnership Project (3GPP), different users have different services, having different requirements on delay, bitrate, packet loss etc. Therefore, a number of bearers are set up for a user equipment accessing a network, bearers providing different quality of service (QoS)1 e.g. one for voice, one for video and one for other services. The latter could provide best effort QoS to other services. Maybe the user equipment (UE) only uses one of the bearers which have been set up. The bearers having no traffic for a predefined time, is timed out and the eUTRAN radio base station (the eNodeB) will initiate a release of the bearer, by requesting bearer release from a Mobility Management Entity (MME). This is done per timed-out bearer.
When the UE has several bearers active it is often likely that more than one of them will timed out at about the same time, e.g. within a few seconds. This can occur e.g. for standard bearers that are set up when connecting to the network. If the connection to the network is made to e.g. perform a signalling procedure only, the bearers will not be used and they will all time out at about the same time.
The prior art solution, having one signalling procedure for each bearer release, is shown in fig. 2, in which B1 indicates the time-out for bearer 1 , B2 the time-out for bearer 2 and B3 the time-out for bearer 3. When the time-out for bearer 1 B1 occurs, the eNodeB 15 sends a bearer release request 21 to the MME 10 and the MME 10 sends a bearer release command 22 back to the eNodeB 15, which forwards the bearer release command 23 to the UE 18. The UE 18 sends a bearer release complete message 24
back to the eNodeB 15, which sends a bearer release complete message 25 to the MME 10. Each bearer time out will result in a bearer release procedure involving the eNodeB 15, the MME 10 and the UE 18 and result in a lot of signalling in the network costing radio and wire transport resources.
SUMMARY
Accordingly, it is an objective with the present invention to provide an improved method in a communication network node of minimizing signalling in a communication network system in which a number of bearers are set up between a user equipment and said communication network node, whereby unused bearers are to be released after a timeout occurrence.
According to a first aspect of the present invention this objective is achieved through a method as defined in the characterising portion of claim 1 , which specifies that signalling in a communication network system is minimized by a method in which a pre-determined period of time is set up when a first time-out occurs among said unused bearers. When said pre-determined period of time has ended, release of bearers which have been timed out during said pre-determined period of time is initiated.
Another objective with the present invention is to provide an improved method in a user equipment of minimizing signalling in a communication network system in which a number of bearers are set up between the user equipment and a communication network node, whereby unused bearers are to be released after a time-out occurrence.
According to a second aspect of the present invention this other objective is achieved through a method according to the characterising portion of claim 7, which specifies that signalling in a communication network system is minimized by a method in which a bearer release command is received from said communication network node for releasing bearers which have been timed out during a pre-determined period of time set by said communication network node when a first time-out occurs among said unused bearers.
A further objective with the present invention is to provide an improved communication network node of minimizing signalling in a communication network system in which a number of bearers are set up between a user equipment and said communication network node, whereby unused bearers are to be released after a time-out occurrence.
According to a third aspect of the present invention this further objective is achieved through a communication network entity according to the characterising portion of claim 9, which specifies that signalling in a communication network system is minimized by a communication network node comprising means for setting a pre-determined period of time when a first time-out occurs among said unused bearers and means for initiating release of bearers which have been timed out during said pre-determined period of time, when said pre-determined period of time has ended.
A still further objective with the present invention is to provide an improved user equipment of minimizing signalling in a communication network system in which a number of bearers are set up between the user equipment and a communication network node, whereby unused bearers are to be released after a time-out occurrence.
According to a fourth aspect of the present invention this further objective is achieved through a user equipment according to the characterising portion of claim 15, which specifies that signalling in a communication network system is minimized by a user equipment comprising means for receiving a bearer release command from said communication network node for releasing bearers which have been timed out during a pre-determined period of time set by said communication network node when a first timeout occurs among said unused bearers.
Further embodiments are listed in the dependent claims.
Thanks to the provision of methods and arrangements, which provide a delayed bearer release procedure in which only one signalling procedure is needed, signalling load on nodes and transport network will be saved.
Still other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures and procedures described herein.
BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows a simplified view of an eUTRAN communication system;
Figure 2 shows a prior art bearer release procedure;
Figure 3 shows a bearer release procedure according to the present invention;

DETAILED DESCRIPTION A communication system, such as an eUTRAN system is shown in fig. 1 , including a Radio Access Network (RAN), comprising at least one Radio Base Station (RBS) (or eNode B) 15a and 15b. The RAN is connected over an interface such as the S1 -interface to an Evolved Packet Core (EPC) 10 comprising e.g. a Mobility Management Entity (MME) which handles control signalling for instance for mobility.
The RAN and the mobile core provide communication and control for a plurality of user equipments (UE) 18 (only one shown in fig. 1 ). The UEs each uses downlink (DL) channels and uplink (UL) channels to communicate with one RBS at a time over a radio or air interface.
According to a preferred embodiment of the present invention, the communication system is herein described as an eUTRAN system. The skilled person, however, realizes that the inventive method and arrangement works very well on other communications systems as well and may be applied in WiMAX. The user equipments may be mobile stations such as
mobile telephones ("cellular" telephones) and laptops with mobile termination and thus can be, for example, portable, pocket, hand-held, computer-included or car-mounted mobile devices which communicate voice and/or data with the RAN.
In the present invention the signalling in the communication network system is minimized by delaying the release of the first bearer a pre-determined period of time, up to T seconds, in order to catch possible more bearer releases in the same signalling procedure. This is illustrated in fig. 3, in which the time-outs for three bearers B1 , B2, B3 have occurred before the eNodeB 15 sends a bearer release request 21 for all three bearers B1, B2 and B3 to the MME 10 when the pre-determined period of time T has ended. The MME 10 sends a bearer release command 22 back to the eNodeB 15, which forwards the bearer release command 23 to the UE 18. The UE 18 sends a bearer release complete message 24 back to the eNodeB 15, which sends a bearer release complete message 25 for all three bearers B1 , B2 and B3 to the MME 10. The pre- determined period of time, T, can be set different for different services and different systems. E.g. release of a service subject to debiting per time cannot be delayed so that extra cost is applied to the user, while a service subject to debiting per transferred byte may be delayed some longer.
Thus, the procedure in a communication network node, such as eNodeB, for minimizing signalling in a communication network system in which a number of bearers are set up between a user equipment and said communication network node, whereby unused bearers are to be released after a time-out, as shown in fig. 4, is as follows:
• when a first time-out occurs among said unused bearers, setting a pre-determined period of time T (step 41 );
• when said pre-determined period of time T has ended, initiating release of bearers which have been timed out during said pre-determined period of time T (step 42), by sending a bearer release request to a second communication network node, such as a MME; • receiving bearer release command from said second communication network node (step 43);
• sending a bearer release command for said timed-out bearers to said user equipment (step 44);
• receiving from said user equipment a bearer release complete message when said timed-out bearers have been released (step 45).
• sending a bearer release complete for said timed-out bearers to said second communication network node (step 46).
Corresponding procedure in a user equipment for minimizing signalling in a communication network system in which a number of bearers are set up between said user equipment and a communication network node, whereby unused bearers are to be released after a time-out, as shown in fig. 5, is as follows:
• receiving a bearer release command (step 51 ) from said communication network node for releasing bearers which have been timed out during a pre-determined period of time T set by said communication network node when a first time-out occurs among said unused bearers;
• sending a bearer release complete message back to the communication network node (step 52).
Figure 6 is a block diagram showing a user equipment 18 and a communication network node 15, such as the eNodeB, for minimizing signalling in a communication network system in which a number of bearers are set up between the user equipment and the communication network node, whereby unused bearers are released after a time-out. The communication network node 15 comprises a radio transmitter 62 and a receiver 61. The transmitter 62 is transmitting data to a receiver 67 of the user equipment 18 over the radio interface on a downlink channel 17. The receiver 61 is receiving data from the transmitter 66 of user equipment 18 on an uplink channel 16. The communication network node further comprises means 63 for setting a pre-determined period of time T when a first time-out occurs among the unused bearers and means 64 for initiating a release of bearers which have been timed out during said pre-determined period of time T, by sending a bearer release request to a second communication network node, such as a MME (not shown in fig. 6). This is explained in more detail above in conjunction with fig. 3.
The user equipment 18 comprises a radio transmitter 66 arranged to transmit data packets to the receiver 61 of the communication network node 15 over the radio interface on the uplink channel 16 and a receiver 67 arranged to receive data packets transmitted from the transmitter 62 of the communication network node 15 on the downlink channel 17. The receiver 67 of the user equipment 18 is further arranged to receive a bearer release command for bearers that has been timed-out during a pre-determined period of time set by the communication network node 15 when a first bearer time-out occurs. And,
the transmitter 66 of the user equipment 18 is further arranged to send a bearer release complete message when the timed-out bearers have been released. The user equipment 18 further comprises means 68 for controlling the release of the bearers, i.e. releasing bearers when the bearer release command has been received in the receiver 67 and being responsible for the bearer release complete message sent by the transmitter 66.
Thus, while there have been shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
