Embodiment
Below describe embodiments of the invention in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label means same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
The present invention mainly is how to make access network equipment can obtain the characteristic information of MTC equipment, in order to solve this purpose, the present invention proposes various embodiments makes access network equipment can obtain the characteristic information of MTC equipment, it should be noted that these embodiment are not only applicable to the 3G system, also be applicable to the LTE(Long Term Evolution) system, and other communication systems of Future Development.In one embodiment of the invention, wherein the MTC characteristic information comprises: Hypomobility, the time controllability, the time tolerance, only support the PS territory, online transmitting small data packets, the off-line transmitting small data packets, the group of take manages as unit, safety connects, initiating communication, exhaled on a small quantity, the MTC monitoring, the off-line indication, disturb indication, the high priority alarm, position informing etc., certainly the characteristic information of MTC equipment is not limited to above-mentioned listed, do not get rid of the new characteristic information of follow-up increase, within the characteristic information newly increased also should be included in protection scope of the present invention.
Below just in the mode of specific embodiment, the present invention is introduced; but these embodiment realize preferred version of the present invention; but be not that the present invention only can realize by following examples; those skilled in the art can make modification or the variation be equal to following examples of the present invention, within the modification that these are equal to or variation all should be included in protection scope of the present invention.
Embodiment mono-,
As shown in Figure 1, determine and comprise the following steps the flow chart of method for the characteristic information of the MTC equipment of the embodiment of the present invention one:
Step S101, MTC equipment is in access network, by RRC message, the characteristic information of MTC equipment is sent to access network equipment (as RNC or eNB), wherein, RRC message can comprise: request message, RRC connection setup complete message, ability Indication message are set up in the RRC connection, or other MTC equipment are to the RRC message of network side transmission.
In one embodiment of the invention, the multiple mode that how to adopt message to carry the characteristic information of MTC equipment has been proposed, these modes not only go for carrying in the RRC message of the present embodiment, also can be applied in following embodiment, for example also can carry by NAS message, or other networks
Mode one: provide a bit to be indicated for each characteristic, have how many characteristics how many bits are just arranged, and do expansion for the more reserved bits of follow-up characteristic and use.
Mode two: the multiple characteristic that may simultaneously support can be combined, form a plurality of feature collections, and feature collection is numbered, the numbering of the feature collection that this MTC equipment of transmission is supported in message gets final product.
Mode three: the characteristic with correlation can be bound to a characteristic group, after all characteristics are divided into groups, for each group provides the information of 1 bit, be used to indicate the characteristic whether this MTC equipment supports this group.The indication bit of transmission characteristic group in message.
Mode four: the characteristic indicating mode that adopts implicit expression.As: report some attributes relevant to characteristic, just know the corresponding MTC characteristic that terminal has when network side receives the attribute of terminal to report.Be exemplified below: when terminal has the Information Transmission Properties of small data quantity, can report to the networking side the needed resource size information of communication (as: concrete bit value) of small data quantity, when network side receives resource size information, just think that MTC equipment has the Information Transmission Properties of small data quantity.Similarly, to the indication with other MTC characteristics, also can adopt same way as, as: can report the translational speed relevant parameter for the terminal with Hypomobility characteristic; For the MTC equipment with time tolerance, can report the maximum tolerable time etc.
It should be noted that, these four kinds of modes can be applied to, in all methods that this patent protects, can be carried by the RRC signaling, also can be carried by the NAS signaling, and other network entity interface signalings are carried.And do not get rid of other modes.
