Definitions
- the present invention relates to signaling a second radio network controller a measurement made in a first radio network controller and, more particularly, to a problem relating to interpretation of such signaling.
- Each controller that receives this generic value can interpret this information in different ways, depending on the maker. For example, 40% could mean congestion in one controller while for a connected controller from another vendor this might not be considered congested. In addition, a generic value cannot report what type of congestion has occurred. It would be useful to know if it is interference, transport overload, or processing overload so that the receiving controller can better decide what it should do to solve the congestion situation. But in a multi- vendor environment, each vendor can define the value in a different way and each controller can analyze the value in a different way. This is fine for communicating between controllers made by the same vendor, but this doesn't work properly in a multi-vendor environment.
- An object of the present invention is to provide a way for a second controller to interpret a report from a first radio network controller concerning congestion conditions in the first controller so that the second radio network controller can be placed in a position to alleviate the congestion.
- method and apparatus are provided for determining in a first controller that an overload condition exists, signaling a second controller that the overload condition exists and a proposed action to alleviate the overload condition.
- the signaling can be done in a same message or in separate messages.
- the proposal could be to restrict data flow, carry out an interf equency handover, carry out an intersystem handover, release one or more radio bearers, or the like.
- the second controller can receive the signaling from the first controller and carry out the proposed action to alleviate the overload condition.
- the alleviation of the overload condition can be carried out in various ways including the above mentioned restriction of data flow, interfrequency or intersystem handover, or releasing of one or more radio bearers.
- the present invention adds an additional parameter, by which a first controller
- controller which performs the measurement suggests a desirable reaction for a second controller (controller which receives the suggested action), in addition to the generic "load" value (which is current solution). Because the second controller receives a proposed action, it can take appropriate responsive action in order to solve the congestion situation in the first controller especially in a multi- vendor environment.
- This invention can be used by the third generation partnership project (3 GPP) universal terrestrial radio access network (UTRAN).
- 3 GPP third generation partnership project
- UTRAN universal terrestrial radio access network
- RNC-RNC 3GPP inter radio network controller
- Such others could include an inter base station controller (BSC-BSC) interface, or an inter base transceiver station (BTS-BTS) interface in which one controller can provide an action proposal to the other controller to solve a congestion situation.
- BSC-BSC inter base station controller
- BTS-BTS inter base transceiver station
- Fig. 1 shows the known 3GPP architecture.
- Fig. 2 shows details of the UTRAN of Fig. 1.
- Fig. 3 shows measurement reports or generic load measurements between RNCs, according to a proposal of the prior art.
- Fig. 4 shows a generic load measurement reported on the Iur interface, according to a proposal of the prior art.
- Fig. 5 shows a difficulty of the prior art proposal of Figs. 3 and 4 in a multi- vendor environment.
- Fig. 6 shows an example of a procedure according to the present invention in which a proposed action to alleviate congestion is proposed in addition to the generic load report from a first RNC of vendor X to a second RNC of vendor Y.
- Fig. 7 shows a second example, according to the present invention, of a proposed corrective action reported from a first controller to a second controller in a multi- vendor environment.
- Fig. 8 shows details of an exemplary means for carrying out the present invention.
- Fig. 1 shows the known 3 GPP architecture 10 with a core network (CN) 12 connected to a UTRAN 14 by an lu interface.
- the UTRAN 14 is connected to user equipment (UE) 16 via a Uu interface which is a radio interface.
- Fig. 2 shows some details of the UTRAN connected to the CN 12 including a pair of radio network servers (RNSs) 18, 20.
- RNSs radio network servers
- Each RNC is connected to a plurality of Node Bs 26, 28, 30, 32 by corresponding Iub interfaces.
- the Node Bs correspond to the base transceiver stations of the global system for mobile communications (GSM).
- GSM global system for mobile communications
- a 3GPP release 4 work item "RRM Optimization on Iur” was started to solve this problem.
- a common measurement procedure was proposed in the above mentioned Change Request 323 to TS 25.423 v 3.4.0 so as to allow a first RNC to request a neighboring, second RNC to report common measurements over the Iur.
- the proposed common measurement procedure there are four common measurement types defined: (1) "load”, (2) “transmitted carrier power”, (3) “received total wide band power”, and (4) "UL timeslot ISCP” (see Table 9.2.1.x at page 122 of CR 323 titled “Common Measurement Type”).
- the present invention improves the type (1) common measurement, i.e., the "load” type.
- an additional information element which allows the first RNC source to suggest a possible reaction for the second, receiving RNC.
- This IE can be used as a flag to signal a meaning in parallel with the generic load parameter.
- the IE can, for example, have following values: - Not loaded
- the receiving second RNC can consider this information in order to alleviate the congestion situation.
- the receiving RNC could be made to reply back to the first (source) RNC. This is of course not exhaustive of the possibilities. More congestion alleviation actions could be added.
- a time element could be added for the execution of the proposed action.
- Fig. 6 shows an example of an RNC from vendor X signaling an RNC from vendor Y of a high load situation and that it will not admit new radio bearers with a priority larger than 4 with the smaller numbers having the highest priority, i.e., with 1 being the highest priority. It is up to the receiver RNC what action to take.
- Fig. 7 shows another example of the RNC from vendor X signaling a very high load with a proposed congestion action.
- RNC X signals RNC Y that it will not admit new radio bearers with a priority larger than 2.
- RNC X also proposes for RNC Y that radio bearers A and B be handed over.
- Fig. 8 shows an exemplary first RNC that includes means for carrying out the improved signaling of the present invention.
- a first (source) RNC 22a means 80 are provided for determining an overload condition exists and for signaling on a line 82 of the existence of the overload condition.
- Means 84 are provided for signaling the overload on a line 86 on the Iur interface to a second (receiving) RNC 24a with a generic load value IE, according to the prior art.
- the means 84 also signals on a line 88 to a means 90 for deciding upon a proposed action and signaling same on a line 92 within a new IE to the second RNC 24a.
- such an IE could include a proposed congestion action such as (1) restriction of data flow, (2) interfrequency handover, (3) intersystem handover, (4) release radio bearer, or the like.
- the means 80 can also include means for determining the nature of the overload and conveying that information on the lines 82, 88 to the means 90. Alternatively, this information can be provided on the line 92 to the second RNC. It should be realized that instead of separately, the signals on the lines 86, 92 may be transmitted in the same message on a same signaling line Iur. Likewise, the means 84, 90 can be combined into a single means for carrying out both functions.
- means 94 are provided for receiving the signaling on the Iur interface for interpreting both the generic value on the line 86 and the information element on the line 92 with the proposed action.
- an instruction signal is provided on a line 96 to means 98 for carrying out any action proposed by the IE signal from the first RNC, if the second RNC decides to carry out the proposed action or carry out some other action.
- a response is not shown in Fig. 8, such would normally be provided back to the first RNC from the second RNC if the elementary procedure (EP) adopted according to this invention is of the class 1 type with a response (success or failure) contemplated.
