Abstract
A first base station receives an application protocol message from a second base station. The second base station communicates employing at least one backward compatible carrier and at least one non-backward compatible carrier. The application protocol message comprises a identifier of the second base station, cell identifiers, and information identifying a carrier type. The base station operates a wireless device handover based, at least in part, on information in the second application protocol message.
Claims20
A method comprising:
- a) transmitting, by a first base station, a first message to initiate an association between said first base station and a second base station, said first message comprising a first initiation tag;
- b) receiving, by said first base station, a second message from said second base station, said second message comprising:
- i) a second verification tag, said second verification tag equal to said first initiation tag;
- ii) a second initiation tag;
- iii) a first state parameter comprising:
- (1) at least one parameter related to operational information of said association;
- and
- (2) a message authentication code generated as a function of a private key;
- c) transmitting, by said first base station, at least one third message to said second base station;
- said at least one third message comprising:
- i) a first verification tag, said first verification tag equal to said second initiation tag;
- and
- ii) a parameter comprising said first state parameter;
- d) receiving, by said first base station, at least one fourth message from said second base station, said at least one fourth message comprising:
- i) an acknowledgement for the receipt of said parameter;
- and
- ii) a second application protocol message, comprising:
- (1) a identifier of said second base station, said second base station comprising a plurality of carriers comprising:
- (a) at least one backward compatible carrier;
- and
- (b) at least one non-backward compatible carrier, a first common reference signal overhead of each of said at least one non-backward compatible carrier being substantially lower than a second common reference signal overhead of each of said at least one backward compatible carrier;
- (2) at least one mobility management entity group identifier;
- (3) a cell identifier for each of said at least one backward compatible carrier;
- and
- (4) information identifying a carrier type for each of said plurality of carriers, said carrier type being one of at least a backward compatible type and a non-backward compatible type;
- and
- e) operating, by said first base station, a wireless device handover employing said association and based, at least in part, on information in said at least one fourth message.
