Abstract
The embodiment of the invention discloses a method and device for indicating UE network support characteristics. The method comprises the following steps that: when a network side allocates a new TAI LIST for a user terminal through the GUTI REALLOCATION process, the network side sends an indicative GUTI REALLOCATION COMMAND carrying the new TAI LIST and the network support characteristics of TA corresponding to the new TAI LIST to the user terminal; and the network side receives a GUTI REALLOCATION COPPLETE message sent by the user terminal. In the invention, when GUTI REALLOCATION is executed as an independent process, UE can acquire the new TAI LIST allocated in the process and the support condition of the corresponding network support characteristics.
Description
Technical field
The present invention relates to communication field, relate in particular to a kind of method and apparatus of the UE of indication network support characteristic.
Background technology
IMS (IP Multimedia Subsystem, IP multimedia system) is a kind of brand-new multimedia service form, and it can satisfy, and present terminal client is more novel, the demand of more diversified multimedia service.At present, IMS is considered to the core technology of next generation network, also is to solve to move with fixed network to merge, and introduces the important way of differentiation business such as voice, data, the triple fusions of video.
PS (Packet Switching, packet switching) is also referred to as packet switch, and it is that the data that the user transmits are divided into certain length, and each part is called a grouping.Add a packets headers in the front of each grouping, where mail to the location in order to indicate this grouping, by the address mark of switch according to each grouping, they are forwarded to the destination then, this process is called packet switching.
After introducing the IMS business, whether network supports this network characteristic of IMS over PS by ATTACH (adhering to) process and TAU (tracing section updating) process, RAU (position renewal) process indication UE (User Equipment, user terminal) network.
At present, in 3GPP standard TS23.401 and TS24.301, how defined in ATTACH, RAU, TAU process indication network requires to add the indication of whether supporting above-mentioned network characteristic to the support of network characteristics such as IMS over PS, urgent call in ATTACH ACCEPT, TAU ACCEPT, RAU ACCEPT message.
At this network characteristic of IMS over PS, to mention among the TS23.401, this indication is that per TAI LIST is effective.So-called TAI LIST is exactly a tabulation, wherein includes a plurality of TA sign of (Tracking Area is called for short TA).This TAI LIST is used to define one group of tracing area.That is to say that this indication is corresponding to the pairing tracing area of TAI LIST that comprises in ATTACH ACCEPT, TAU ACCEPT.
Above-mentioned ATTACH, RAU, TAU process are the protocol procedures of Non-Access Stratum, i.e. network support characteristic is by the protocol procedures notice UE's of Non-Access Stratum.And in UE, each network characteristic is realized that by upper layer application separately from the protocol hierarchy angle, upper layer application is positioned on the Non-Access Stratum protocol hierarchy, so after the Non-Access Stratum of UE is notified, need be notified to corresponding upper and uses.For example, the upper layer application of this network characteristic of IMS over PS in UE is SIP, and after Non-Access Stratum obtained the whether support of network to this network characteristic of IMS over PS, this application of notice SIP should be used for making follow-up operation by SIP.
In the EPS system, also defined this Non-Access Stratum process of GUTI REALLOCATION (GUTI heavily distributes), this process can be used for distributing new GUI and/or new TAI LIST to UE.When distributing new TAI LIST, the zone of the tracing area of new TAI LIST correspondence and the TAI LIST correspondence of distributing to UE before this may be different to the degree of support of network characteristics such as IMS over PS, illustrate as follows: the old TAI LIST of UE is TAI tabulation 1, and the TAI 1 pairing tracing area of tabulating is supported this network characteristic of IMSover PS.It is TAI tabulation 2 that network is assigned new TAI LIST by GUTI REALLOCATION process to UE, and the pairing tracing area in the tabulation 2 is not supported this network characteristic of IMS over PS.In this process, the TAI LIST of UE tabulation changes and variation has also taken place for the network characteristic supported, but but not notify this TAI LIST of UE be the tabulate support situation of this network characteristic of IMS over PS of tracing area of 2 correspondences of TAI to network.
UE can't know that new TAI LIST is that the tabulate tracing area of 2 correspondences of TAI supports the situation of this network characteristic of IMS over PS, the upper layer application SIP of UE still to think this network characteristic of network support IMS over PS.This makes that network that upper layer application SIP knows is different to the support situation of the support situation of this network characteristic of IMS over PS and real network characteristic, and this will cause SIP to use judgement and operation of making is wrong.
Another example is, old TAI LIST is that the tabulate tracing area of 3 correspondences of TAI is not supported this network characteristic of IMSover PS, and the tracing area of new TAI LIST to be TAI tabulate 4 correspondences is supported this network characteristic of IMSover PS.At this moment, the UE upper layer application thinks that still network do not support this network characteristic of IMS over PS, and this will cause the user can't in time use this network characteristic of IMS over PS.
Therefore, the shortcoming of prior art is:
When GUTI REALLOCATION carries out as separate processes, UE can't be known the situation of the support of network characteristic by the GUTIREALLOCATION process, the upper layer application that causes UE timely and accurately awareness network to the support situation of network characteristic, think mistakenly that perhaps network to the support situation of network characteristic, significantly reduces the satisfaction of user experience.

By the method that adopts embodiments of the invention to provide, network side is that user terminal is when distributing new TAI LIST by the GUTIREALLOCATION process, indication in the network support characteristic of the TA that in the GUTI REALLOCATION COMMAND that user terminal sends, carries new TAI LIST and new TAILIST correspondence, thereby the upper layer application that makes user terminal and user terminal can be accurately or current network network characteristic and/or the unsupported characteristic supported, make the upper layer application of user terminal carry out operation accurately accordingly, strengthen user experience.
Embodiments of the invention two provide a kind of method of the UE of indication network support characteristic, as shown in Figure 2, may further comprise the steps:
Step 201 when network is UE when distributing new TAILIST by GUTI REALLOCATION process, indicates the network support characteristic of the TA of new TAI LIST and this new TAI LIST correspondence to be included among the GUTI REALLCATION COMMAND.
Concrete, the network support characteristic of the TA of the TAI LIST correspondence that this is new can adopt a new information unit (Information Element, i.e. IE) sign, and this paper is called network feature supportIE (indication of network support characteristic).
Concrete, the GUTI REALLCATIONCOMMAND message structure that adds after IE indicates is as shown in table 1:
Table 1
In the middle of the table 1, the content of last column is the new IE instruction content that adds, and when UE received GUTICOMMAND message and this message handled, the particular content when whether UE occurs and occur according to IE was finished mutual with upper layer application.
For example, if this IE does not occur, then UE thinks that network do not support all characteristics.If this IE occurs, then UE resolves this IE and determines network support and/or do not support which network characteristic according to the concrete content of this IE.
For example, at IMS over PS ability, UE knows by the IE in GUTI COMMAND message indication whether network supports this network characteristic of IMS over PS in the zone of new TAI LIST correspondence, and should whether support to indicate and be notified to the SIP application layer.
For example, UE is known this network characteristic of the pairing tracking area support of newly assigned TAI LIST IMS over PS according to the indication networkfeature support IE in the GUTI REALLCATION COMMAND message.
Concrete, represent the field of network characteristic support and be illustrated as example that the 1-8 of first row is used to illustrate the bit order of this field in the table 2 with being used among this IE shown in the table 2, each bit wherein can be used to refer to the degree of support of network to a network characteristic.Be exemplified below: wherein the 1st, 2,3,4 be respectively applied for the degree of support of indication network characteristic A, B, C, D.Residue bit keeps, and is used for the following new network support characteristic that occurs.In the table second row is the actual value of this field, according to each bit explanation.If network support characteristic A, B, when not supporting characteristic C, D, then corresponding the 1st, 2bit is set to 1 respectively, and corresponding the 3rd, 4bit is set to 0 respectively.
Which network characteristic network and UE are used to indicate for each bit, and identical understanding is arranged.
Network and UE also have identical understanding for specifically expressing support for and unsupported bit value (0 or 1).
Table 2
| Bit is along several numbers | ?8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
| The actual value of each bit of field | ?0 | 0 | 0 | 0 | 0 | 0 | 1 | 1 |
After UE searches and comprises the indication IE of network support characteristic in the GUTI REALLCATION COMMAND message, further search the bit of this IE correspondence, know the network characteristic that the pairing tracking area of newly assigned TAI LIST is supported according to the network characteristic of each bit correspondence.
Especially, when the TA of the former TAI LIST of user terminal correspondence had the network characteristic of support, user terminal was judged the network characteristic of the current newly-increased support of network according to the indication of the network characteristic that TA supported of new TAI LIST correspondence, and reports upper layer application flexibly.For example, if the network characteristic that the TA of TAI LIST correspondence before this supports comprises characteristic A, characteristic B, unsupported characteristic comprises characteristic C, characteristic D; The network characteristic that the TA of new TAI LIST correspondence supports comprises characteristic A, characteristic C, and unsupported characteristic comprises characteristic B, characteristic D.Described UE need not the corresponding characteristic A to described user terminal at this moment, the upper layer application of characteristic D is indicated, only need to make indication to the corresponding characteristic C of described user terminal, the upper layer application of characteristic B, promptly indicate the application network of characteristic C correspondence to support characteristic C now, the application network of indication characteristic B correspondence is not supported characteristic B now.
Concrete, when UE is known the indication that does not comprise network characteristic in the GUTI REALLCATION COMMAND message, for example during network feature support IE, UE judges that the pairing tracking area of newly assigned TAILIST will not support all-network characteristic among the network feature support IE, the UE notice realizes the upper layer application of these network characteristics, and current network is not supported these network characteristics.
Concrete, network side can be Mobility Management Entity or other equipment, embodiments of the invention do not limit this.
Especially, in the embodiments of the invention, it with network feature support IE this network characteristic indication of IMS over PS that is not limited in current definition in the indication of network characteristic of example, those of ordinary skill in the art is to be understood that, for the indication of other network support characteristic of redetermination, the method for the network characteristic indication that embodiments of the invention provide stands good.
Especially, in the embodiments of the invention, to search the result who whether carries new TAI LIST among the GUTIREALLCATION COMMAND be after carrying new TAI LIST to user terminal in the step 203, described user terminal can also be with the indication to network characteristic that comprises among the described GUTI REALLCATION COMMAND, directly report application layer, carry out corresponding operation according to the indication of described network characteristic by application layer.
